DEFRA exempt stoves and smoke control areas: Leeds, York and beyond
In a smoke control area you can only burn wood on a DEFRA-exempt stove. Most of Leeds is covered, York extends its rules city-wide from November 2026, and elsewhere the maps vary street by street. Nearly every stove we fit is exempt, and we check your exact address on the survey.

What a smoke control area actually is
Councils designate smoke control areas under the Clean Air Act, and inside one you may not release smoke from a chimney unless you are burning an authorised fuel or using an exempt appliance. For wood, that means the stove itself must be DEFRA exempt: tested and approved to burn wood cleanly enough for the zone.
The rules attach to the address, not the postcode town, which is why the honest answer to "am I in one?" is a check against the current council map rather than a guess. We do that check as part of every free home survey.
Where Leeds and York stand
Most of Leeds has long been covered by smoke control orders, so for practical purposes a Leeds woodburner should be a DEFRA-exempt one. York is mid-change: parts of the city are covered today, and the council has confirmed the rules extend city-wide from November 2026, so any stove fitted in York now should simply be exempt from day one.
Across the rest of our patch, from Wakefield to the coast, coverage is patchier and set by each council. The same principle holds everywhere: check the address, fit exempt, and the question disappears.
What makes a stove DEFRA exempt
An exempt stove has passed emissions testing that proves it burns wood cleanly enough for smoke control areas, usually through refinements that stop the fire being starved of air into a smoulder. In day-to-day use that engineering is invisible; the stove simply burns well.
Nearly every woodburner we supply carries the exemption, from the ACR cast range through the Fire FX stoves to the Poppy, so choosing an exempt model costs nothing in choice or character.
The fuel half of the equation
The law is only half about the appliance; the other half is what you burn. Dry, seasoned wood or Ready to Burn certified logs keep any stove clean and legal; wet wood makes smoke in any appliance and tars your flue while it does it. Burn dry wood on an exempt stove and you are inside the rules with room to spare, whatever the map says.
Common questions
How do I find out if my house is in a smoke control area?
Your council publishes the current map, and we check it for your exact address as part of the free home survey. The rules attach to addresses, not towns, so a proper check beats a general answer every time.
Can I burn wood in Leeds?
Yes, on a DEFRA-exempt stove, which is how we specify Leeds installations as standard since most of the city is covered by smoke control orders. Nearly every stove we fit carries the exemption.
What changes in York in November 2026?
The council extends smoke control rules city-wide from 1 November 2026, where previously only parts of the city were covered. Any stove fitted in York now should simply be DEFRA exempt, and everything we propose there is.
Are DEFRA-exempt stoves worse to use?
Not at all, and usually the opposite: the same engineering that earns the exemption makes the stove burn wood more cleanly and efficiently. There is no character penalty and no meaningful price penalty across our ranges.
What happens if someone burns wood illegally in a smoke control area?
Councils can issue fines for smoke emissions in the zone. It is an entirely avoidable problem: an exempt stove and dry wood put you inside the rules permanently, which is why we specify that combination as standard.
