Planning permission, building regulations, and finding an installer

You may not need planning permission to install a wood-fuelled boiler, but you should always check - permitted development rights have made installations much simpler. All new wood heating systems have to comply with building regulations, and the best way to ensure this is to use an installer who is a member of a Competent Person Scheme.

Planning permission  

Installing renewable energy technologies, such as biomass boilers, has been made a lot simpler thanks to permitted development rights. Read about these at the government's site for UK legislation:

You must check with your local authority in case other conditions apply, but in general wood-burning boilers and stoves are permitted as long as:

  • flues on the rear or side elevation of the building are no more than a metre above the highest part of the roof
  • in a conservation area or a World Heritage site, the flue is not be fitted on the principal or side elevation if it would be visible from a highway
  • the building is not listed or in a designated area (in which case you may need permission for internal alterations too)
  • in Scotland, the flue is not in an Air Quality Management Area.

If the project also requires an outside building to store fuel or related equipment the same rules apply to that building as for other extensions and garden outbuildings.

The government's Planning Portal has useful information:


Building regulations  

All new wood heating systems have to comply with Building Regulations. The government's planning portal has a PDF of the Domestic Building Compliance Guide 2010 (see section 5).

  However, the simplest way to comply is to use a member of a Competent Person Scheme such as  HETAS.  You can find a list of all the relevant schemes here.  If you use a member of an appropriate scheme your installer will ensure your system is safe and legal, and certify that your system complies, so there will be no need for you to contact the local building control office.


Smokeless zones  

If you live in a smoke control area, you will need to use an exempt appliance. These are available for all types of wood heating system. To find out whether you are in a smoke control area, contact the Environmental Health or Protection department of your Local Authority. Find out your local authority throughout the UK at the DirectGov website.

England: Find out your local authority at the DirectGov website

Scotland: Find out your local authority in Scotland at the DirectGov website

Wales: Find out your local authority in Wales at the DirectGov website

Find an installer  

The Energy Saving Trust recommends that you choose a certified wood fuel system and a certified installer. Both the system and the installer will have to be accredited under the Microgeneration Certification Scheme (MCS) for you to eligible for any support under the Renewable Heat Incentive.

For advice on certified products and installers available in your area:

  • call Home Energy Scotland on 0808 808 2282
  • visit the MCS website 
  • look for an installer or supplier signed up to an industry code of practice
  • speak to people in your area who have had a wood fuel installation and ask if they would recommend their installer.

Check that the installers are members of the Renewable Energy Consumer Code (RECC). Members of the scheme agree to abide by its Consumer Code. The code covers issues such as pre-sales activity, contracts including deposits and payment schedules, completing the order and after-sales activities. In particular, sales staff must not use any high-pressure selling techniques, including:

  • staying in your home for an unreasonably long time
  • offering you a high initial price followed by a discount
  • offering you a discount for signing on the day
  • withholding price information from you until the end of the visit
  • claiming that there is limited availability of a product.

For MCS certification, a company must belong to a consumer code which is backed by the Trading Standards Institute. RECC is currently the only approved code within the industry and sets out high standards in relation to consumer protection, requiring installers to provide protection against excessive deposit payments and workmanship warranties. 

The installer should also be a member of a Competent Person scheme or you will have to get approval from the local Building Control Office for the installed system.


What to look for in an installer

All wood fuel installers should be able to provide a detailed breakdown of the specification and costs of their proposed system. They should also be able to explain how they have calculated the size of the system to be appropriate for your needs, supply good quality user documentation/ operating manual and details of actions you will need to do to maintain your system. Get at least three installers to specify and cost some potential options for you. Use the checklist below to help you choose an installer:

Check any professional credentials being quoted. Ask if they are:

  • a certified installer
  • a member of a trade organisation - if so, find out the association's membership criteria
  • a registered competent person- if not you will need to notify and pay your local council’s building control department to check the installation.

Pick a supplier with experience. Ask how long they have been in business, and how many years they have been installing systems for.

Choose local where possible. Ask for a list of references and local installations and check them. Get lots of information on system options and potential problems. Ask for recent manuals and brochures. Check the time limits of any guarantees and warranties and find out what they cover.

Ask for details of:

  • after-installation services offered
  • warranties - all installers should provide a minimum one year warranty on the installation
  • what the warranties cover and over what time periods.

Do not compare installers on cost alone; the cheapest may not be the most appropriate.

Ask for details of:

  • available options, for example, size, fuel type and availability of hot water storage
  • appliance capacity and how often it would be expected to need refuelling on a typical winter day and during a very cold spell
  • independent testing of appliances to verify any stated efficiencies
  • applicable regulations, for example, smoke free zones, health and safety,  ventilation guidelines and how they will address them.

Check quotations for detail. Ask about:

  • government incentives – will the system be eligible for Renewable Heat Incentive payments?
  • payment options
  • what is included – prices should cover safe removal and disposal of any existing equipment, for example, your old boiler
  • whether they are also able to supply fuel or are able to recommend a supplier.
