Installing a biomass boiler is one way to reduce your long-term energy bills and your environmental impact, as these boilers use non-fossil fuels from sustainable sources in order to heat your home.

In this article, we look at:

  • How much biomass boilers cost
  • What affects the cost of installing a biomass boiler
  • How to save money on your biomass boiler installation
  • The advantages and disadvantages of using a biomass boiler
  • How to find a professional to fit and install one

If you’re wanting to switch your energy type to something more sustainable, keep reading to find out how you can integrate biomass power into your home in the most cost-effective way.

How Much Does a Biomass Boiler Cost?

The cost of installing a biomass boiler depends in part on the type of fuel you plan to use, and how the fuel is fed into the boiler.

The table below explains the estimated cost of different biomass heating systems:

Log Boiler £10,000 to £15,000 1 to 2 days
Wood Chip Boiler (manually-fed) £14,000 to £16,000 1 to 2 days
Wood Chip Boiler (automatically-fed) £10,000 to £25,000 1 to 2 days
Pellet Boiler (manually-fed) £15,000 to £25,000 1 to 2 days
Pellet Boiler (automatically-fed) £20,000 to £35,000 1 to 2 days

Estimates last reviewed in November 2022.

As shown in the table above, biomass log boilers can cost anywhere from £10,000 to £15,000. In most cases, installing a log-fuelled boiler is a straightforward process and should take just one or two days.

If you plan to use wood chips, the cost varies depending on whether you want to feed the woodchips into the boiler, or whether you prefer an automatic system. The cost of manually-fed wood chip boilers ranges from approximately £14,000 to £16,000.

If your budget allows, an automatically-fed wood chip boiler typically costs between £10,000 to £20,000. Both variants take between one and two days to install.

Pellet biomass boilers are a sustainable and efficient way to heat your home. If you don’t mind occasionally topping up an auger or hopper, you can purchase a manually-fed pellet boiler for £15,000 to £25,000.

As you might expect, biomass boilers with an automatic pellet feeder are more expensive and could cost you as much as £20,000 to £35,000.

As with the other types of biomass boilers, the pellet versions usually take between one and two days to install.

What Affects the Cost of a Biomass Boiler?

As we saw above, biomass boiler costs can vary quite considerably. In this section, we take a more detailed look at the factors that influence the overall cost of installing a biomass boiler.

The Size of Your Home

Unsurprisingly, the size of your home has a direct impact on the overall cost of the biomass boiler you need. This is because you’ll need a more powerful boiler to effectively heat your home.

The size of your home can also affect the overall cost of running your biomass boiler. In particular, you may need to run your boiler for slightly longer than average in order for every room in your house to reach the desired temperature.

Boiler Output and Your Choice of Design

Biomass boiler costs also depend on the output and design of the boiler you choose.

If you’re going to invest in a biomass boiler, it makes sense to choose a model that is powerful enough to effectively heat your home⁠—whether it’s a 2-bedroom bungalow or a sprawling estate.

However, the higher the output of your boiler, the more expensive it’s likely to be.

To determine what output you need for your home, you need to consider the size of your home and your energy consumption. Domestic biomass boilers usually range in output from 15 to 56 kilowatts (kW). A 15 kW biomass boiler should comfortably heat a one- or two-bedroom home.

The cost of your biomass boiler also depends on the design.

As shown in the price comparison table above, biomass boilers can be manually fed or automatically fed. Whilst log biomass boilers are always manually fed, wood chip or pellet boilers have both manual and automatic feeding options.

Automatically-fed boilers can be fed through an integrated hopper or auger (which you must top up yourself using bagged pellets or wood chips), or through a separate aboveground or below-ground storage unit (which allows you to buy bulk quantities of pellets or wood chips).

In terms of size, pellet boilers are generally more compact than wood chip boilers. Wood chip boilers are often bigger than pellet boilers due to the bulky auger which feeds the chips into the boiler.

Further to these options, there are also pellet stoves, which are among the more affordable choices for biomass heating, and are especially suited to smaller homes.

Your Choice of Fuel

Before purchasing a biomass boiler, it’s a good idea to consider fuel costs. Below, we look at some of the more common types of biomass fuel, as well as newer fuels such as miscanthus and various grains.

Please note: the current energy crisis has led to a substantial increase in demand for wood fuel in the UK, as homeowners seek out alternative ways of heating their homes through biomass boilers and wood-burning stoves.

In addition, the UK and many other European countries have suspended imports of certain wood fuels from Russia and Belarus due to the conflict in Ukraine. These two factors have led to a substantial increase in biomass fuel costs, with the cost of some fuels rising threefold. The prices given below reflect our best estimates during this period of uncertainty.


Logs are among the most affordable biomass fuels. They have a calorific value of approximately 4.1 kWh per kilogram, which is higher than wood chips but lower than wood pellets. This makes logs a reasonably efficient source of biomass fuel.

Logs are usually sold by the cubic metre, and you should expect to pay between £100 and £300 for a pallet.

The cost varies by supplier and also depends on whether you choose softwood or hardwood logs. Softwood timber burns more quickly and is less efficient, but more affordable.

On the other hand, hardwood species – especially oak, beech, ash, and birch – are denser and therefore burn longer than softwoods like pine.

For more information on how to choose logs for your biomass boiler, see this Forestry Commission guide.

No matter what type of logs you choose, remember to factor in the cost of your time, as logs must be manually fed into the biomass boiler—usually every day.

Wood Chips

Wood chips have a calorific value of 3.5 kWh per kilogram, which means they are less efficient than logs or wood pellets.

However, they are another affordable source of biomass fuel—particularly if you live in a rural area and you can fell your own trees.

To do this, you’ll need a fuel-grade chipper to turn the timber into biomass. Alternatively, hiring a chipper generally costs around £200 per hour, plus travel time.

If you can’t source your own wood chips, buying wood chips could cost you between £80 and £150 per tonne, depending on the supplier and delivery method.

Wood Pellets

Pellets are much denser than logs and wood chips. They have a calorific value of 4.8 kWh per kilogram, which is considerably higher than wood chips or logs.

Whilst pellets are the most efficient fuel choice for biomass boilers, they are also the most expensive type of biomass fuel. Currently, wood pellets cost anywhere from £400 to £700 per tonne.

The cost varies depending on whether the pellets are tipped out onto your property (less expensive), delivered into your storage unit using a blown system, or delivered to you in bags (most expensive).


Miscanthus is a type of grass (sometimes also called elephant grass) that originates in parts of Asia, southeast Africa, and the South Pacific. Currently, it’s most commonly used for animal bedding in the UK.

Miscanthus is a relatively new fuel for biomass boilers. It has a calorific value of roughly 3.6 kWh per kilogram, which makes it about as efficient as wood chips.

Since miscanthus grows so quickly and is a perennial plant, it’s one of the cheapest and most environmentally sustainable sources of biomass fuel.

If you have a large property, you could even consider growing your own. Planting a hectare of miscanthus costs approximately £1,200 to £1,500 and the rhizomes should remain productive for up to 20 years.

However, not all boilers are suitable for burning miscanthus.

This is because miscanthus burns at a lower temperature and produces more ash than other fuels. This can lead to unpleasant residue inside your boiler, and potentially increase your maintenance costs.

However, adding a small quantity of slaked lime to your chopped or pelleted miscanthus can increase the burning temperature and alleviate some of these challenges.

Miscanthus also naturally contains more moisture than wood fuels, so you need to ensure it remains as dry as possible.


Farmers have long known the potential value of grain as biomass fuel, but it remains new to the domestic biomass boiler market.

Multiple types of grain can be used as biomass, including barley, oats, and wheat. Barley has a calorific value of approximately 4.3 kWh per kilogram. Wheat has a calorific value of 4.6 kWh per kilogram, which makes it almost as efficient as wood pellets.

Like miscanthus, grains also burn at a lower temperature than wood and create more sticky ash that can block your boiler and prove hard to remove. Mixing your choice of grain with a small percentage of slaked lime can prevent this from occurring.

The Quantity of Fuel You Need

How much fuel you need depends in part on the size of your home, how much energy your family consumes, and the type of fuel you choose.

As a general guide, you can calculate how much fuel you need by dividing the output of your biomass boiler by 4. If you have a 15kW boiler, you’ll need approximately 3.75 tonnes of fuel per year.

This means that you could spend approximately £300 to £560 per year on wood chips, or £1,500 to £2,625 per year on pellets.

For log boilers, fuel is sold by the cubic metre, not by the tonne. To convert tonnes of fuelwood to cubic metres, simply multiply by 1.38. For a 15kW log boiler, you might spend approximately £520 to £1,550 per year on fuel depending on your choice of timber.

Whichever fuel you choose, you should only purchase biomass fuels through a supplier that is certified by HETAS or Woodsure. This ensures that your fuel is high quality, and doesn’t contain too much ash or harmful contaminants that could gum up your boiler and pollute the air.

To find a reputable supplier, search the government’s Biomass Suppliers List.

The Cost of Storing Your Fuel

In addition to the cost of buying your boiler and fuel, you’ll need to sort out a way to store your fuel.

Biomass fuel must be kept dry and free of dust and pests, so a proper fuel storage system is a worthwhile investment. Fuel that is too damp won’t burn efficiently (if at all) and dust and debris can gum up your boiler, leading to potentially higher maintenance and servicing costs.

Depending on which fuel you use and how much you need to store, you may be able to use an auger, a hopper, or an aboveground or below-ground storage system.

Adapting Your Existing Heating System

If you plan to switch your existing heating system to a biomass boiler, you may need to make certain adjustments.

For example, if you don’t currently have a hot water cylinder, you may need to buy one so you don’t have to wait for hot water. This can cost between £850 and £3,500 depending on brand and size.

It may also be necessary for you to have new radiators and pipework installed—something your heating specialist will be able to advise you on.

Maintenance and Servicing Costs

Burning biomass logs, wood chips, or pellets always creates some ash, which must be emptied every one to four weeks. If you buy high-quality fuel and keep it dry, your boiler should produce less ash.

A biomass boiler service can cost between £180 and £450, depending on the output of your boiler, the type of fuel you use, and your location. At a minimum, biomass boilers need to be serviced at least once a year, and possibly more often depending on how much you use them.

Biomass boilers are undoubtedly an investment, but there are some ways to potentially reduce your costs.

First, do your research to see if you’re eligible for a grant through the Boiler Upgrade Scheme, which replaces the previous Clean Heat Grant. Under this scheme, you could receive a government grant of up to £5,000 towards the cost of a biomass boiler. For full details on who is eligible for a biomass boiler grant, visit the government’s website.

Second, you may want to consider a manually-fed boiler. Though you will need to devote some time and attention to adding more fuel each day, these boilers are more affordable than automatic or vacuum-fed machines.

Third, think carefully about the type of fuel you want. As we saw above, there is always a trade-off between fuel efficiency and cost. Wood chips and logs are reasonably efficient and cost anywhere from £80 to £300 per tonne.

Conversely, wood pellets are currently the most efficient fuel available but they could cost you up to £700 per tonne.

You can also explore biomass boilers that are designed to burn newer types of fuel, such as miscanthus and grain.

Finally, if you are keen to invest in a biomass boiler, it’s worth knowing that homeowners and businesses occasionally decommission their existing biomass boilers and may want to sell them on. Only a small number of retailers offer used biomass boilers, but it could be worth investigating given the upfront costs.

If you’re considering a secondhand biomass boiler, do your research and check the following:

  • How much will it cost to install compared to a new biomass boiler?
  • Is the manufacturer’s warranty still valid? For how long?
  • What grant can I receive from the Boiler Upgrade Scheme?

Can a Biomass Boiler Save Me Money or Reduce My Bills?

Choosing a biomass boiler is an investment, but it’s worth looking at how much you could save by switching to biomass. The table below illustrates how much you could potentially save—and reduce your carbon footprint—in Great Britain and Northern Ireland:

Older Gas Boiler (G-rated) Up to £820 Up to 3,800 kg per year Up to £2,400 Up to 5,500 kg per year
Newer Gas Boiler (A-rated) Up to £90 Up to 2,300 kg per year Up to £940 Up to 3,100 kg per year
Older Electric Storage Heater Up to £2,500 Up to 2,600 kg per year Up to £2,000 Up to 3,600 kg per year
Newer Electric Storage Heater Up to £1,500 Up to 1,600 kg per year Up to £1,200 Up to 2,500 kg per year
Older Oil Boiler (G-rated) Up to £470 Up to 6,500 kg per year Up to £1,700 Up to 8,500 kg per year
Newer Oil Boiler (A-rated) Loss of up to £260 Up to 3,900 kg per year Up to £455 Up to 4,800 kg per year
Older LPG Boiler (G-rated) Up to £1,200 Up to 4,400 kg per year Up to £4,300 Up to 6,500 kg per year
Newer LPG Boiler (A-rated) Up to £325 Up to 2,700 kg per year Up to £2,100 Up to 3,500 kg per year
Coal Up to £630 Up to 11,000 kg per year Up to £430 Up to 11,000 kg per year

Estimates last reviewed in November 2022. The figures above are based on converting an existing heating system to a pellet biomass boiler in a 4-bed detached house with basic insulation. Source: Energy Savings Trust.

As the table above shows, switching to a pellet biomass boiler can substantially reduce your annual energy bills.

For example, if you currently own an old gas boiler with an EPC rating of G, switching to a biomass boiler could save you as much as £820 per year according to the Energy Savings Trust.

If you have an old electric storage heater lurking in your home, your savings could be even higher—up to £2,500 per year. Even homes with newer electric heating systems could benefit from switching to a biomass boiler, with potential savings of up to £1,500.

If your home is off the grid and you’re currently relying on an older G-rated oil-fired boiler, switching to a biomass boiler could leave you with an extra £470 per year. Alternatively, if your home relies on LPG fuel for heating, you could save approximately £325 to £1,200 depending on the age of your boiler.

For homeowners still reliant on coal heating, a biomass boiler could result in savings of up to £630 every year.

However, not all homeowners may see a financial benefit from converting to a biomass boiler. Indeed, the Energy Savings Trust estimates that switching from a newer A-rated gas or oil boiler to a biomass boiler could cost you an extra £260 per year.

Though switching to a biomass boiler can be more expensive in some cases, it’s also worth considering how a biomass boiler can reduce your carbon footprint.

Changing to a biomass boiler substantially reduces the amount of carbon dioxide (CO2) that’s produced as a result of heating your home—especially if you switch from an older gas, oil, or LPG boiler (or from coal).

If reducing your carbon footprint is important to you, switching to a biomass boiler or installing one in your new home is a great way to lower the environmental impact of heating your home.

In Northern Ireland, switching to a biomass boiler can save you between £430 and a massive £4,300 per year. In contrast to Great Britain, every homeowner in Northern Ireland could save money by switching to a pellet biomass boiler—even those who own a newer A-rated oil boiler.

Earning Money Through the Renewable Heat Incentive

As we saw above, most homeowners can save money by switching to a biomass boiler.

In addition to reducing your energy costs, you may be able to further reduce your bills by getting payments through the Renewable Heat Incentive (RHI).

This is a government scheme that aims to encourage homeowners to use renewable energy sources for domestic heating by providing financial incentives.

It’s important to note that the government closed the scheme to new applicants on 31 March, 2022. However, if you’ve purchased a home that already has a biomass boiler, you may be able to receive payments by applying for a change of ownership.

The amount of money (or tariff) you receive from the government depends on the date your biomass boiler was accredited through the RHI.

If your boiler was accredited way back in April 2015, you could receive up to 11.02p per kWh. However, if your boiler was accredited more recently, you should expect a tariff of 7.39p per kWh. The current list of tariffs is available here.

Are Biomass Boilers Expensive to Run?

To give you an idea of biomass boilers and their running costs, below are the price estimates for 2022 as compared to other energy sources:

Biomass Pellets 7.9p 7.3p
Electricity (Standard Rate) 34p 16.4p
Gas 10.3p 12.3p
LPG 12.1p 11.3p
Oil 9.2p 9.3p
Coal 5.2p 6.2p

Estimates last reviewed in November 2022. Your actual costs may vary according to your choice of heating system, your usage, and your tariff. Source: Energy Savings Trust.

In 2021 (the most recent data available at the time of publication), homeowners across Great Britain paid an average of £564 for gas, on top of an average of £769 for electricity.

In Northern Ireland, energy prices vary substantially by supplier. The price of heating oil increased 89 per cent from 2021 to 2022, but it appears that average gas bills have increased even more. For electricity, customers of the largest electricity supplier in Northern Ireland are now paying an average of £944—an increase of 55 per cent from April 2021.

As the table above shows, biomass pellets cost just 7.9p per kWh in Great Britain, or 7.3p per kWh in Northern Ireland.

In contrast, you could pay anywhere from 9.2p per kWh to as much as 34p per kWh for heating in Great Britain, or between 9.3p per kWh and 16.4p per kWh for residents of Northern Ireland.

Though coal is still cheaper than biomass, biomass has a far lower carbon footprint and can be an especially good choice for homeowners living in rural areas.

Despite the large upfront cost, biomass boilers are cheaper to run than most conventional heating systems.

Is a Biomass Boiler Right for Me?

It can be hard to decide whether or not a biomass boiler is right for you—especially when they carry such high purchase and installation fees, and can cause some disruption at home to get going.

Here are the main advantages and disadvantages of these boilers for you to consider.

Environmentally friendly, reducing the amount of carbon dioxide (CO2) that’s produced as a result of heating your home High initial costs for fitting and purchasing the biomass boiler
You can receive a grant of up to £5,000 off the cost and installation of the boiler Only possible for those who own their homes and can change their heating systems
Environmentally-friendly credentials They won’t always save you money if you’re switching from a newly-fitted, A-rated boiler
Can be enticing to future housebuyers for the green credentials You’ll need a lot more space than you will for traditional heating systems

The main advantages of biomass boilers are their green credentials, being enticing to future housebuyers as well as the existing eco values they give the existing homeowner. They’re a great alternative to fossil fuels, making them a popular choice.

For the downsides, the up-front price is something to bear in mind. Some automatically-fed boilers can cost in excess of £25,000, although you can look to cut down costs by opting for a manually-fed boiler instead.

How Can I Apply For a Biomass Boiler Grant?

At the time of writing, the UK government is offering grants to homeowners to encourage them to switch to low-carbon household heating systems, such as biomass boilers and heat pumps, through the Boiler Upgrade Scheme (BUS).

It is one grant per property, and the money can be given as such, according to the .gov website:

This can help to absorb some of the high up-front costs of installation for new heating types in homes. You’ll need to own the property in question, and it must have a valid EPC rating which doesn’t recommend cavity insulation to be eligible for the scheme.

There is also the Energy Companies Obligation (ECO) scheme which can offer a grant towards the installation of low-carbon heating sources. Under the Energy Companies Obligation (ECO) scheme, low-income households can be entitled to upgrade to an energy-efficient boiler, either free of charge or at a sizeable discount.

You must meet the following criteria:

  • You must own your home
  • If you live in council housing, it must have an EPC rating of E, F, or G
  • If you live in rented accommodation, the property must have an EPC rating of A, B, C, D, E, F, or G and you must have permission from the landlord

However, as per Ofgem, under the ECO, grants for biomass boilers are only available for rural properties not connected to the gas network, and even then, only if a heat pump is deemed unsuitable for the property.

Frequently Asked Questions

How Do Biomass Boilers Work?

Simply put, biomass boilers work by burning biological fuel and using that heat to warm your home.

Do I Need Planning Permission for a Biomass Boiler?

For a typical domestic installation, you won’t need planning permission, as long as the work is internal.

If you own a listed building or are in any covenants, you’ll need to check your individual status with your local council.

What Size Biomass Boiler Do I Need?

Choosing the right boiler mainly depends on how much energy you consume and the size of your home. Energy consumption varies from home to home but, as a starting point, check your utility bill to see how many kilowatts (kW) of energy you use each year.

To calculate output based on the size of your home, convert the size of your home into cubic metres, then divide by 30. (If your home is very well insulated, you can divide by 50 instead.) This will give you the boiler output you need in kW.

Do Biomass Boilers Work as Well as Gas Boilers?

Biomass boilers are marginally more efficient than gas boilers.

Whereas gas boilers have a peak efficiency of between 88 and 91 per cent, the efficiency of biomass boilers can range from 89 to 91 per cent.

How Long Do Biomass Boilers Last?

Biomass boilers can last up to 20 years, if they are well-maintained and regularly serviced.

This means that biomass boilers can outlive most conventional boilers, which have a typical lifespan of 10 to 15 years.

How Often Should I Service My Biomass Boiler?

The answer depends in part on how often you use your boiler.

As a general rule, it’s a good idea to book a service every 2,500 running hours or once a year—whichever comes first.

What Can You Burn in a Biomass Boiler?

Different biomass boilers can accommodate various types of fuel, including wood chips, logs, pellets, briquettes as well as newer alternatives such as oats, barley, wheat, and miscanthus.

Be sure to only burn the type of fuel recommended for your particular boiler.

How Many Pellets Does a Biomass Boiler Use?

Biomass pellets have a typical calorific value of 4.8 kWh per kilogram. By contrast, wood chips have a calorific value of 3.5 kWh per kilogram, whilst logs have a calorific value of approximately 4.1 kWh per kilogram.

This means that biomass pellets are more efficient at generating heat than either logs or wood chips.

The quantity of pellets you need to heat your home depends on the size of your home and how much you’re using your boiler. For example, if you wanted to heat a typical 3-bed terraced house throughout the entire day, you’d need approximately 10 to 15 kilograms of pellets per day.

How Long Do Wood Pellets Last?

Wood pellets can last indefinitely if kept in the right environment.

The key to preserving your pellet supply is to ensure they are kept dry and at a consistent temperature. Choosing a good, airtight hopper or silo will protect your pellets from exposure to water and pests. Likewise, try to keep your pellets in a temperature-controlled environment that doesn’t get too hot or too cold throughout the year.

This will help ensure that your pellets continue to burn with maximum efficiency and prevent you from losing your pellets to rot.

Where Can I Buy Fuel for My Biomass Boiler?

The government’s Biomass Suppliers List is an excellent resource for finding a biomass fuel supplier. The site allows you to narrow your search by fuel type, including wood chips, logs, pellets, and briquettes.

To ensure that your fuel is high quality and will burn efficiently without gumming up your boiler, it’s a good idea to buy fuel from HEATAS or Woodsure certified supplier.

Can a Biomass Boiler Be Outside?

Yes, outdoor biomass boilers are available for those who don’t have the space inside their homes. Many outdoor models are still relatively compact, and carry many of the same features as indoor boilers.

Are Biomass Boilers Cheaper to Run Than Gas?

Yes, biomass boilers are currently cheaper to run than gas boilers.

According to the Energy Savings Trust, biomass pellets cost 7.9p per kWh in England, Wales, and Scotland and approximately 7.3p per kWh in Northern Ireland.

On the other hand, gas costs 10.3p per kWh in Great Britain and 12.3p in Northern Ireland.

Are Biomass Boilers Noisy?

Biomass boilers are not known for being noisy. They typically make less noise than a traditional gas boiler, so you may find that your home is quieter after switching to a biomass heating system.
