The Most Successful Defra Approved Stove List Experts Have Been Doing Three Things
What is a Defra Approved Wood Burning Stove?

If you reside in a zone of smoke control then you must purchase a DEFRA exempt stove. A DEFRA exempt stove (or SE) permits you to legally burn wood in a smoke-controlled area.

They are independently tested to provide the lowest emissions possible. Stoves that have this status are usually branded with the 'Defra approved logo on their specifications or name.

Approved for Smoke Controlled Areas

Many people believe that living in a smoke controlled area means they can't use a wood burning fireplace. This isn't the case. In reality, many cities and large towns are within a smoke-free zone, however this doesn't mean that you cannot have a stove, it just implies that you have to make use of an exempt device and only use authorised fuels (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 meets certain criteria regarding the emissions it produces when burning authorised materials. It is therefore able to be used legally in areas of smoke control.

The Defra Logo is widely used in the industry, and many stoves have the SE after their names to indicate they are smoke-free. In order for a stove to be SE approved, it must satisfy strict criteria in regards to its emissions and emissions, so you can be certain that if you select a defra exempt stove you will receive the cleanest and most efficient wood stove available.

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

A stove that is Defra-approved permits you to install a 5" liner that is compliant with UK building regulations. Non-Defra-approved stoves require an 6" liner.

Stovax is proud to offer a variety of Defra-approved stoves and fireplaces and Ecodesign Ready stoves which have been designed with future standards for air quality in mind. In fact, many of our Defra approved stoves are capable of being used with smoke control kits for those properties that are in a Smoke Control Area and can therefore be used with a variety of approved smokeless fuels, including fire logs.

Approved for Smokeless Fuels

The only stove that can be installed inside a smoke-control zone is one that is a DEFRA approved wood burner, also referred to by the designation DEFRA exempt. DEFRA stoves price range should be used with a solid fuel, which is wood, and preferably well-seasoned. The government tests these stoves to ensure that they don't release excessive smoke and that they can only be used with 'authorized' fuels.

The difference between the differences between a DEFRA approved stove and one that isn't typically is very small. A lot of modern stoves can be converted to DEFRA certified by a kit that is supplied by the manufacturer and installed in a matter of minutes. This is because the Defra approved stove must undergo rigorous testing and must be restricted to the amount of smoke it is able to produce.


To ensure that these limitations are maintained during testing the stove must be able to limit the combustion air supply to ensure that it does not starve itself of oxygen, which can cause it to smoke. This is done through a mechanism within the stove that allows an air pocket into the firebox during combustion which is usually hidden within the stove and beneath the base of the fire box.

Stove World UK offers a wide range of DEFRA approved stoves from some of the country's best manufacturers including Stovax, Arada and Burley. They are available in a huge variety of styles and finishes. Select from a broad selection of Ecodesign stoves, which are designed to meet the upcoming needs for air quality.

Smoke Control Areas are primarily situated around cities and towns with large populations and you can look up the official website of your local authority to determine if your area is classed as such. It is essential to buy an approved DEFRA-approved stove if reside in a smoke-controlled zone. This will allow you to avoid being fined by your local authority. If you burn coal or other solid fuels using a non approved stove, you could be fined up PS300.

Approved for Wood

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

Many older wood stoves emit lots of particles into the air, which can cause or contribute to respiratory issues, asthma attacks, heart issues and premature death. It is therefore important to buy a wood stove that meets strict emission standards established by the Environmental Protection Agency. Look for the "EPA 2020 Certified Label" which means that the wood stove meets the emission limits currently in place.

If you purchase a stove which is not EPA-certified and you reside in a smoking zone you'll have to get it recertified before you can use the stove. find out here can be time-consuming and expensive, but the law requires it. find out here who decide to sell a property with wood stoves that are not certified may also be liable for tax credits or fines related to clean air.

Modern stoves can be altered to become Defra approved by a kit or an adjustment that the installer provides. This is due to the primary difference between the DEFRA approved stove and those that are not, is the combustion air management system that controls how much air passes through the stove during normal operation. Modifications are usually done to the base or the side of the firebox that is underneath the stove.

Some manufacturers produce two versions of their wood stove, one that is Defra approved and the other that is not. This is due to the process of putting a stove through the strict Defra tests is expensive, so to help recoup some of the costs, they'll offer the non-approved model at a lower price. The DEFRA approved version will have been able to have the modification to the combustion air done as part of the testing process.

Gas Approved

Before the Clean Air Acts were brought in homes for residential use, homeowners could burn any type of fuel they wanted, which resulted in large quantities of smoke emissions and health issues. To stop this, Defra established Smoke Control Areas. This meant that homes could not emit any smoke except if their wood burners and multifuel stoves were approved by Defra for burning only authorised materials such as manufactured smokeless coke and anthracite.

Defra approved stoves, also referred to as SE (Smoke Exempt) Stoves, have undergone rigorous testing to demonstrate that they are able to burn cleanly authorised fuels within a Smoke Control Area. The latest technology for combustion delivers an unabated minimum of secondary air into the firebox. This lets the stove meet Defra standards for Smoke Control Areas even when it is using authorised fuels like anthracite as well as manufactured smokeless coals.

The Stove Yard has a wide range of Defra-approved stoves that are perfect for those who live in a smoke control zone and require a brand new fireplace that burns wood. We have a broad selection of Defra-approved stoves. These include traditional models, modern and inset that are made by top manufacturers such as Stovax. Arada, Burley, and AGA.

The good news is there is no visual difference between a stove approved by Defra and a non-approved model. However the models that are Defra-approved include a few features designed to help them burn more efficiently. They generally have a different grate design as well as air vents. On the gas models they may also feature an outlet for the flue that is different in size.

A Defra Approved Stove will almost always have 5" flue outlet (125mm). This means that you can use a smaller stainless steel twin wall flexible liner that is less expensive than a 6" (150mm). We've used this when customers have an older or non-standard chimney stack that we are installing a Defra approved wood-burning stove in and also saves the expense of relining the chimney with a larger diameter liner.
