What we offer


HETAS Approved Retailers give you confidence in getting a suitable, efficient and safe wood burning or biomass appliance for your home. All approved retailers contain at least one HETAS trained showroom staff member, meaning quality advice can be given to the end-user that meets a good standard of service.


HETAS is the only competent person scheme specialising in the installation of solid fuel and biomass appliances. The HETAS ‘Find Installer’ search makes it easy to find your nearest HETAS Installer of solid fuel, wood and biomass appliances.

Chimney Sweeps

A good chimney is essential to the continuing efficient and safe operation of all solid fuel burning heating and cooking appliances. HETAS recommends that chimney sweeping is best carried out by a HETAS Approved Sweep at least once a year, depending upon the appliance and fuel being used.


Servicing your stove is critically important if you want to keep it operating efficiently and safely. HETAS servicing technicians can give your stove the expert attention it needs to ensure it can perform safely and efficiently. Our search allows you to filter for servicing for stoves, stoves with boilers and biomass systems.

HETAS Governance

HETAS Limited (known as HETAS). The acronym stands for Heating Equipment Testing and Approval Scheme. The Company is a legal entity and operates as a company limited by guarantee; not having any share capital.
Our purpose is: Working together for a cleaner and safer environment.

To achieve this we commit to the following objectives and providing a service to the industry:

As a certification body, we are responsible for all of its certification activities. An agreement between HETAS and its clients takes in to account the responsibilities of each of the certification schemes.

As an industry lead expert, we work closely with government, appliance and chimney manufacturers, installers, fuel producers, distributors and all manner of associated parties from across the biomass sector with the goals of advancing training, raising awareness and improved end-user safety in this exciting, emerging, renewable arena.

As a not for profit organisation the Company is governed by an industry body of Members (previously called “the Council”).  These Members offer general direction and guidance from an independent industry perspective for the on-going activities offered by HETAS. They also have a say in any surplus funds offered to pursue the purpose of HETAS.

Impartiality Committee

An Impartiality Committee is established in order that HETAS has a management commitment to operate openly, objectively and impartially in accordance with the Product Certification Standard BS EN ISO 17065:2012, whilst operating as a certification body for assessing companies to the Microgeneration Certification Scheme product and installer standards, and MHCLG’s competent person authorisation criteria for registrants’ self-certifying work under the Building Regulations.

The Impartiality Committee membership is made up of representatives from relevant stakeholders, with a committee elected Chairperson independent of HETAS. The structure of the committee will have a balance of interest where no one group predominates.

The presence of objectivity is understood to mean that conflicts of interest do not exist, or are resolved so as not to adversely influence the activities of the body. Anyone wishing to raise an objection around the objectivity of the certification process can in the first instance contact the elected Chairperson via the HETAS quality representative.

HETAS Technical Committee

The HETAS Technical Committee: In achieving our objectives we bring together representatives of key stakeholder groups to help voice the views of the industry and to help HETAS maintain a strong safety and technical focus.

HETAS commits to support this committee where views and actions align with the overall objectives of HETAS and support HETAS registrants for the installation of solid fuel burning appliances and associated equipment or services. The output from this committee provides the industry with an opportunity to influence and review industry standards and regulation at a British and European level.

Stakeholders wishing to be considered to join the HETAS Technical Committee can express their interest to the HETAS Technical team.

Complaints about HETAS Staff or Policies/Processes

If your complaint relates to a Registered Business or installation, or you are unhappy with a complaint outcome, please contact the HETAS Compliance Team in the first instance; they will be happy to discuss your concerns and aim for resolution.

There may be times when people or organisations feel dissatisfied with the service provided by HETAS or a member of our staff.

Should this matter arise, we would ask that complaints are made in writing and sent via email or post, addressed to the relevant department.
