What is a Defra Approved Wood Burning Stove?

If you live in an area where smoke is controlled, it's important to purchase a DEFRA-exempt stove. A DEFRA exempt stove (or SE) allows you to legally burn wood in a smoke controlled area.

The stoves are independently tested for the lowest emissions possible. Stoves with this certification typically have the logo 'Defra-approved' in their name or on their specifications.

Approved for Smoke Controlled Areas

Many people think that living in a Smoke Control Area means you can't have a stove that burns wood however this isn't true. In reality, Defra Legislation Stoves most cities and large towns are in a smoke controlled zone however this doesn't mean that you can't have stoves, it just implies that you have to make use of an exempt appliance and only burn fuels that are approved (usually Briquettes) in your stove. The stove that is Defra-approved is a wood-burning stove that has been rigorously tested to ensure that it is in compliance with certain requirements in terms of the emissions it generates when burning approved materials. It can therefore be legally used in smoke-control zones.

The Defra Logo is widely used in the industry, and a lot of stoves feature the SE after their names to indicate that they are smoke-free. To be SE approved the stove must satisfy strict emission criteria. This means you can be sure that you are purchasing the top wood stove on the market.

When you look for a wood burning stove that is Defra exempt or has SE after its name, you will often find that the manufacturer has done things such as made sure there are enough air inlets on the front of the stove to allow for full combustion of the fuel, and that the chimney outlet size is adequate to stop the build-up of soot. This is crucial because it ensures that the smoke from the wood stove does not escape through the chimney and into your home.

Another benefit of a Defra approved stove is that it generally permits you to use it with 5" chimney liner, which is in compliance with UK building regulations, whereas stoves that aren't Defra-approved will have to be fitted with a bigger 6" liner.

Stovax is proud to offer a variety of fireplaces and stoves that are Defra-approved, as well as our Ecodesign Ready stoves which have been designed keeping future standards for air quality in mind. In fact, a lot of our Defra approved stoves are also suitable for use with a smoke control kit for those properties that are in a Smoke Control Area and so can be used with a range of approved smokeless fuels, including fire logs.

Approved for Smokeless fuels

A DEFRA approved wood burning stove, also known as a DEFRA exempt stove, is the only type of stove that you can put in a smoke control area if you plan to use it to burn solid fuel (wood and preferably well-seasoned). They are inspected by the government to ensure that they don't create excessive levels of smoke. They can be used with 'authorised' fuels (coal only).

The difference between a DEFRA-approved kitchen and one that isn't approved is usually minimal. Modern stoves can be made DEFRA compliant with the kit supplied by the manufacturer and installed in just a few minutes. This is because Defra approved appliances must pass very strict tests and are restricted in the amount of smoke they can produce.

To ensure that these limitations remain in place during the testing process, the stove must be able to limit the combustion air supply to ensure that it doesn't deplete itself of oxygen, which could cause it to smoulder. This is accomplished through the mechanism that allows a small amount air into the firebox when it's burning. It is usually concealed inside the stove or underneath the base of the firebox.

Stove World UK has a wide range of DEFRA approved stoves, from some of the top DEFRA stoves brands in the country including Stovax Arada and Burley. These are available in a huge variety of styles and finishes. Pick from a variety of Ecodesign stoves that are designed to meet future demands for air quality.

Smoke Control Zones are predominantly in large towns and cities. You can visit the website of your local authority to see if you live in one of these. It is important to purchase an approved DEFRA stove if you live in a smoke-controlled area. This will allow you to avoid being fined by the local authority. If you use coal or other solid fuels in a non approved stove, you may be fined up PS300.

Approved for Wood

A DEFRA approved stove, also called a smoke-free wood stove is an appliance which can be used to burn wood in a Smoke Control Area. The stove will be stamped with the Defra approved logo or an 'SE' in its name which means it can be used in smoke-controlled areas when burning approved fuels only that is, in this instance, wood.

Many older wood stoves emit huge amounts of particulate matter. This can cause or worsen respiratory problems, asthma attacks and heart problems. This is why it's crucial to purchase new wood stoves that meets the strict emission standards set by the Environmental Protection Agency (EPA). You should look for the "EPA 2020 Certified" label, which indicates that the stove has met the emissions limits currently in place.

If you purchase an appliance that isn't EPA certified and you live in a smoke-free zone, you will need to be able to get it certified before you can use it. It can be costly and time-consuming, but it is legally required. Additionally homeowners who sell a home with an uncertified wood stove could be subject to clean air tax credits and fines.

Modern stoves can be modified to be Defra approved with an adjustment kit or a kit that the installer offers. The major difference between DEFRA approved stoves and those that aren't combustion air control system, which controls the amount of air that flows through the stove when it's in normal operation. Modifications are typically made to the base or side of the firebox that is underneath the stove.

Certain manufacturers make two types of wood stove, one that is Defra-approved, and the other is not. The reason is that the cost of putting a wood stove through the rigorous Defra testing is expensive. To reduce the costs, they sell the non approved version at a cheaper cost. The DEFRA-approved version will have undergone the combustion air modification in the course of the test procedure.

Approved for Gas

Prior to the Clean Air Acts, residential homes were able to burn any fuel they wanted, leading to excessive smoke emissions. This caused health problems. To stop this, Defra established Smoke Control Areas. This meant that residential homes could not emit any smoke except if their wood burners and multifuel stoves were approved by Defra for burning only approved materials such as manufactured smokeless coke and anthracite.

Defra approved stoves, also referred to as SE (Smoke Exempt) Stoves, have undergone stringent testing to prove that they can cleanly burn authorised fuels within a Smoke Control Zone. They achieve this by utilising the latest combustion technology which continuously delivers a minimum amount of secondary air to the firebox, so that even if the stove is used with fuels that are authorised, such as anthracite or manufactured smokeless coals it can still comply with Defra's rules for DEFRA Legislation Stoves Smoke Control Areas.
