Smoke control areas and the fuel restriction

If your home is in a smoke control area, you cannot emit smoke from the chimney unless you are burning an authorised fuel or using an appliance exempted for the fuel you want to burn. In England, emitting smoke in breach of that rule is dealt with by a financial penalty imposed by the council rather than by prosecution, following changes made by the Environment Act 2021. The penalty is set within a range, so check the current figure with your local authority.

A smoke control area is declared by the council under the Clean Air Act 1993. It has nothing to do with planning permission, and a stove installed with permission can still be unlawful to use.

What a smoke control area prohibits

An order made under Part III of the Clean Air Act 1993 covers a defined area, which may be the whole district or part of it. Within that area two things are controlled.

Smoke emission from the chimney of a building, unless the fuel burned is an authorised fuel or the appliance is an exempt appliance approved for that fuel. And the acquisition of unauthorised fuel for use in a building in the area, other than in an exempt appliance.

That second control is the one people miss. Buying a bag of ordinary logs for an unexempted open fire in a smoke control area is itself a problem, separately from whether smoke is seen coming out of the chimney.

Authorised fuels and exempt appliances

Two routes exist and they solve the problem in different ways.

Authorised fuels are smokeless fuels that may be burned in any appliance in a smoke control area. Anthracite, semi-anthracite, gas and low volatile steam coals fall into this group along with a list of manufactured smokeless products. Exempt appliances are stoves and boilers tested and approved for use in smoke control areas, each approved for specified fuels and subject to conditions in the approval.

Both lists are published and both change. Check the current lists, and read the conditions attached to the appliance approval, because an exempt stove approved for dry wood is not approved for anything you happen to put in it.

Separately, and everywhere in England rather than only in smoke control areas, the sale of wet wood in small volumes and of traditional house coal for domestic use has been restricted since 2021. Buying seasoned or kiln dried wood with a moisture content at or below 20 per cent is now the normal route whatever your address.

Checking whether your address is inside one

There is no single national map. Smoke control orders are made by individual councils and held by them, and coverage varies enormously between neighbouring authorities.

Ask the council's environmental health or environmental protection team directly and ask for the answer in writing with the order reference. Some councils publish a map or a list of streets. A search result or a neighbour's opinion is not evidence, and the question is worth settling before spending on an appliance and a lined flue, in the same way as the other checks covered when checking a site for constraints.

If you are buying, the local authority search on a conveyancing transaction will usually reveal it, and it is worth asking the question specifically if a stove is part of the attraction.

Flue height and what it does not do

A taller flue does not take you outside a smoke control area. The controls in the Clean Air Act on chimney heights, and the approval process for them, apply to furnaces and industrial plant rather than to a domestic stove, and a domestic chimney gains no exemption from being high.

What flue height does control is whether the installation complies with the Building Regulations and whether the appliance works. Approved Document J sets out where a flue must terminate relative to the roof, ridges, openings and adjoining buildings, and those distances exist to get products of combustion clear of windows and to give the flue a workable draught.

In planning terms, a flue on a house is often permitted development under Class G of Part 1 of Schedule 2 to the General Permitted Development Order, subject to limits including that it must not exceed 1 metre above the highest part of the roof. On article 2(3) land, which includes conservation areas, National Parks, National Landscapes and World Heritage Sites, a flue is not permitted development on a wall or roof slope fronting a highway. On a listed building, internal and external flue works will usually need listed building consent.

An illustrative example shows the sequence people regret. A household in a Victorian terrace installs an open fire in a reinstated fireplace, unaware that the whole borough has been a smoke control area since the 1970s. They burn ordinary logs. A neighbour complains about smoke drifting into a bedroom, the council writes, and the household discovers that an open fire cannot be made compliant except by burning authorised smokeless fuel. The fix is either a fuel change or an exempt appliance with a lined flue, which is a larger job than the original installation. This example is illustrative.

Enforcement and penalties

Since the Environment Act 2021 amendments, emitting smoke in a smoke control area in England is subject to a financial penalty imposed by the local authority rather than a criminal prosecution. Councils set the penalty within the statutory range, and repeated breaches at the same property can be treated more seriously.

Enforcement usually starts with a neighbour complaint about smoke or smell. Councils generally write first, and a household that switches to an authorised fuel at that point rarely hears more. Ignoring the letters is what produces penalties.

Persistent smoke can also be dealt with as a statutory nuisance under the Environmental Protection Act 1990, which is a separate route with different consequences including an abatement notice. That applies whether or not you are in a smoke control area.

What this means for a proposed wood burning stove

Work through it in this order.

1. Confirm in writing whether the property is in a smoke control area.
2. If it is, choose an exempt appliance approved for wood, and read the approval conditions.
3. Buy fuel accordingly: dry wood at or below 20 per cent moisture, or an authorised smokeless fuel.
4. Check the flue route and termination against Approved Document J before ordering anything.
5. Check whether the external flue needs planning permission because of the property's designation or the elevation involved.
6. Use an installer registered with a competent person scheme, or notify building control, and keep the certificate.

The certificate matters more than people expect. It is what a purchaser's solicitor asks for, and an unregistered installation with no paperwork becomes a retention on a sale.

And check the deeds. A restrictive covenant can prohibit solid fuel appliances or external flues independently of anything the council decides, and the planning system has no power over it.

Where the planning system does come in

Most internal stove installations need no planning permission at all. The planning questions arise with the external flue, with any structural opening in a listed building, and occasionally with a chimney reinstated on a building in a conservation area where the appearance matters to the area's character.

If the property is listed or in a conservation area, take that advice before the appliance is ordered. Set out the proposal and its effect on the building in the supporting documents so that the council sees a considered scheme rather than a flue drawn on an elevation.
