Short answer: yes, you can physically do the work in your own home. No, you cannot just do it and say nothing. Installing a solid fuel appliance is building work, so it has to be either carried out by a competent person registered on an approved scheme, such as a HETAS registered installer who self-certifies, or notified to building control before it starts so they can inspect it.
That is the whole legal answer. The rest of this guide covers what the building control route actually involves, what Approved Document J will be measured against, and the honest arithmetic on whether doing it yourself is worth it.
The two routes
Route one: a registered installer. A competent person registered on an approved scheme does the work and certifies it themselves. You get a certificate, the scheme notifies the local authority on your behalf, and there is no separate building control application. This is what most installations use.
Route two: building control. You do the work, but you tell your local authority building control before you start, not after you finish. They inspect at the stages they choose and issue the completion paperwork at the end. There is a fee, and there is a timetable, and the inspection is of your work.
The mistake that costs money is doing the work first and asking afterwards. Regularising unauthorised work generally means opening the installation back up so it can be seen, and it is a slower and more expensive conversation than a building notice would have been.
What gets checked
Approved Document J is the guidance the inspector or the installer works to. For a solid fuel stove up to 50 kW in England, these are the provisions that decide whether the installation passes.
| Provision | What it asks |
|---|---|
| Air supply (Table 1, 2.2) | A permanent air vent of the required equivalent area, sized from the rated output and the airtightness of the dwelling |
| Hearth (2.22 to 2.28, Diagram 24) | Usually a 125 mm constructional hearth, 840 × 840 mm freestanding, with a clear non-combustible surface around the appliance |
| Flue size (Table 2, 2.4 to 2.6) | At least the Table 2 size for the appliance type, never smaller than the appliance’s own flue outlet or the manufacturer’s figure |
| Flue height and outlet (2.8, Diagram 17) | A minimum flue height of 4.5 m can be satisfactory where the outlet provisions are followed, or calculate to BS EN 13384-1 |
| Clearances (Diagram 19, 2.18) | An uninsulated single wall fluepipe stays at least 3 × its diameter from combustible material, or 1.5 × with a shield; masonry chimneys use the 200 mm and 40 mm figures |
| CO alarm (2.34 to 2.36) | An alarm to BS EN 50291-1:2018 in the same room, 1 m to 3 m horizontally from the appliance |
| Notice plate (1.57, 1.58) | A durable plate recording the hearth, flue and appliance details, fixed where it will be found |
Every one of those has caveats, and several of them hand the final say to the manufacturer’s instructions. Stove Toolkit works each of them out for your installation and cites the paragraph behind the answer, which is the same evidence an inspector will want to see.
The notice plate is not optional
Paragraph 1.57 requires a notice plate giving the location of the hearth, fireplace or the beginning of the flue, the flue category and the appliance types it can serve, the flue type and size (or the liner and its manufacturer), and the installation date. Paragraph 1.58 says it must be robust, indelibly marked, and fixed unobtrusively but obviously — next to the consumer unit, the chimney or hearth, or the water stop-cock.
It is the cheapest part of the job and the one most often skipped. The next person who works on that chimney, or buys the house, is the reason it exists.
The chimney is usually the hard part
Most of the questions that stall a DIY installation are not about the stove. They are about what the stove is connected to: whether the existing chimney is sound, whether it needs lining, what its actual flue size is, whether it passes a smoke test, and whether the terminal position works on that roof. A chimney sweep or installer can answer those in an hour with equipment you probably do not own.
The honest arithmetic
Doing it yourself saves the installation labour. Against that:
- The building control fee and the timetable are real costs, and inspections happen when the inspector is available.
- Documentation follows the house. When you sell, the buyer’s solicitor asks for the certificate. A building control completion certificate answers that as well as an installer’s certificate does; nothing at all does not.
- Insurance. Some policies ask whether a solid fuel appliance was professionally installed or signed off. Check yours before you decide, not after.
- The safety margin. An under-ventilated stove puts carbon monoxide in a living room, and an undersized hearth is a fire risk. These are not defects you notice in use.
A reasonable middle path is common: do the preparation, the hearth and the making good yourself, and have a registered installer do and certify the appliance and flue connection. Agree the split before anyone starts, because a scheme installer can only certify their own work.
Before you order the stove
Two decisions are much cheaper before the appliance is bought than after:
- Rated output. It sets the ventilation requirement, and above 5 kW in an older house it is the difference between needing a permanent vent and not. Our guide on log burner air vents works the numbers.
- Hearth. The footprint and 125 mm thickness can mean structural work on the floor. See wood burner hearth rules.
