Selling a House With a Wood Burner: HETAS & Legal Guide

By Lisa Hayes · 14 October 2026

Yes, you can sell a house with a wood-burning stove, and most buyers love one. What decides whether it helps or hurts the sale is paperwork: a HETAS (or equivalent competent-person) certificate or a building control completion certificate, a working carbon monoxide alarm, and proof the stove is legal where you live. Miss those and a stove becomes a conveyancing problem; have them and it's a selling point.

I've watched sales wobble over a £400 stove more often than over a £40,000 roof. Not because the stove is dangerous (usually it isn't) but because nobody can prove it was installed properly, the buyer's solicitor asks for the certificate, and the seller has no idea where it is. This guide covers the whole lot: what the law actually requires, what buyers and lenders ask for, what to do when the certificate has vanished, smoke control areas, open fires, insurance, and how to present a stove so it adds value rather than questions.

Does a wood-burning stove help or hurt a house sale?

It helps, as long as it's legitimate. A working stove sells the idea of a cosy living room better than any staging trick, and buyers viewing in October or November will walk straight to it. Estate agents list them as a headline feature for good reason.

It hurts when it raises questions you can't answer. A stove with no certificate, a chimney nobody has swept in years, or a flue liner of unknown origin tells the buyer's solicitor there is a hole in the file. Solicitors don't shrug at holes. They write them up as enquiries, and lenders' conveyancers can refuse to proceed without a satisfactory answer.

My honest view: if you have a stove and the paperwork is in order, say so in the first line of the listing. If the paperwork is missing, fix that before you go to market rather than hoping nobody asks. Somebody always asks.

What does the law say about installing a wood burner in the UK?

In England and Wales, installing a solid fuel appliance is covered by Part J of the Building Regulations (combustion appliances and fuel storage systems). The work has to be notified to building control or carried out by a registered installer under a competent person scheme. HETAS runs the main scheme for solid fuel. Scotland and Northern Ireland have their own building standards regimes, with the same practical effect: the installation has to be signed off.

The compliance route gives you one of two documents:

• A HETAS (or other scheme) certificate of compliance, issued by the registered installer, usually with a commissioning sheet and a notice plate fixed near the appliance showing the flue details.
• A building control completion certificate, issued by the council or an approved inspector, if you didn't use a registered installer and went through building control instead.

Either is fine for a sale. What isn't fine is neither. A cousin who "does stoves" or an enthusiastic DIY job from 2014 leaves you with a stove that works but cannot be proved compliant.

The requirement to notify building control for stove installations has been in place for well over a decade, so any stove put in during that period should have paperwork. Older stoves that predate the rules are a different story and I'll come to those further down.

Which documents will a buyer's solicitor ask for?

The seller's side of the form most solicitors use, the TA6 Property Information Form, asks about building work and consents, and fitting a stove counts. A competent buyer's conveyancer will then follow up. Expect to be asked for:

1. The installer's certificate of compliance, or the building control completion certificate.
2. Details of who installed it and when.
3. Evidence of the last chimney sweep or servicing.
4. Confirmation that a carbon monoxide alarm is fitted.
5. If relevant, the smoke control area position and whether the stove is an exempt appliance.

If you're fresh to this, our guide to the full seller's paperwork pack shows where a stove certificate sits alongside the EPC, gas and electrical records and the rest. And if you installed windows or a stove in the same refurbishment, the logic is identical to a missing FENSA certificate: a competent-person document that someone, eventually, will ask for.

What's the difference between HETAS, Gas Safe, Woodsure and a chimney sweep's receipt?

People mix these up constantly, so here is the plain version.

The point: a sweep's receipt does not prove the stove was fitted legally. It proves the flue was clean. Helpful, but a different question.

What if I've lost the certificate?

Don't panic. This is the commonest scenario by far, and it's usually solvable in days.

1. Ask the original installer. If they were HETAS registered, they will have a record. You can check a business's registration on the HETAS website using its Check Business function.
2. Ask HETAS. Certificates for registered installs are logged centrally, and a copy can generally be obtained through them.
3. Ask the council. If building control signed it off, they hold the completion certificate on file. Ring the building control team with your address and the approximate year.
4. Check your old solicitor file. If you bought the house with the stove in place, your own conveyancing pack may contain the certificate. Your solicitor is obliged to keep records, so ask.

If all four draw a blank, you have a real gap, and the next section is for you.

What if it was never certified at all?

Here you have three realistic routes, and I'd rank them in this order.

1. Get it inspected and regularised

Have a HETAS-registered engineer inspect the installation and, where possible, issue a report. Where the work needs regularising, you can apply to the council for a regularisation certificate for unauthorised work. Building control may ask to see the flue, hearth and fixings, and in some cases a CCTV inspection of the liner. It's the cleanest outcome because the buyer ends up with a real certificate and a lender is happy.

2. Get the stove inspected, swept and keep the evidence

Short of full regularisation, a sweep's receipt and a competent engineer's written confirmation that the installation is sound gives the buyer's solicitor something concrete. Some lenders' conveyancers accept this alongside the next option, others won't.

3. Indemnity insurance

A single-premium indemnity policy for lack of building regulations approval is the usual fallback. It protects the buyer against enforcement action by the council over the missing sign-off. The limits matter, though: it doesn't cover a faulty installation, which is the one risk with a stove that actually harms people. So an indemnity policy answers the legal question, not the safety question. I would never use it as a substitute for having someone competent look at the flue.

For the wider picture on missing consents, see our guide to selling a house with problems that put buyers off.

Do I need a carbon monoxide alarm when selling?

Where a solid fuel appliance is installed, Building Regulations require a carbon monoxide alarm in the same room, and HETAS guidance says your installer should confirm it is correctly positioned. Alarms have a lifespan printed on the unit, so check the expiry date. A dead or expired alarm is an easy thing for a surveyor to spot and an even easier thing for you to replace for the price of a decent lunch.

Put a working one in before the first viewing. Test it, note the date.

Do I have to tell the buyer about the stove?

Yes, in effect, because the TA6 asks about building work and alterations, and a buyer's survey will spot a stove in seconds. The real question is how much you say. Answer truthfully and specifically: who fitted it, when, what documents exist, and when it was last swept. Vague answers invite follow-ups. Specific answers close the topic.

Do not tick "no work done" because the stove came with the house and you didn't fit it. If you don't know, say you don't know and hand over what you have. Misleading answers on a property information form are exactly how a completed sale becomes a dispute after the keys change hands. Our guide on property jargon explains the terminology if you hit unfamiliar terms in the paperwork.

What is a smoke control area, and does it affect my stove?

A smoke control area (SCA) is a zone, designated by the local council, where you can't release smoke from a chimney. According to GOV.UK, in an SCA you can only burn authorised fuel unless you use a Defra-approved appliance, called an exempt appliance. Many towns and cities are covered, in whole or in part, and you find out by asking the environmental health team at your council.

• £300maximum penalty in England for smoke from a chimney in an SCA
• £1,000maximum fine for buying unauthorised fuel for a non-exempt appliance
• 2x / 1xHETAS-recommended sweeps per year: wood / smokeless fuel

What this means for a sale:

• If the stove is a Defra-exempt model, you can burn wood on it in an SCA, provided you use the fuel the manufacturer specifies. Keep the manual and model details.
• If it isn't exempt, you may only burn authorised smokeless fuel. A buyer who assumed they'd be burning logs will be less keen. Tell them early.
• Not sure? The model name and number is on the appliance's data plate. Check it against Defra's list of exempt appliances.

Most buyers care about the burn rules. A stove that can legally burn wood where they live is worth more than one that can't. If you're in an SCA, say whether yours is exempt.

What about open fires and old fireplaces?

An open fire is a different animal. There's no "installation certificate" for an old open fireplace in the same sense, and no HETAS sign-off. Buyers still care about three things: is the chimney sound, is it lined or at least swept, and has it been capped or blocked safely if unused?

Smoke control rules apply to open fires as much as stoves. In an SCA you're limited to authorised fuels on an open fire. A blocked-up chimney needs ventilation, because a sealed flue with no airbrick can cause damp. Surveyors flag that routinely, and if you've capped a chimney, the buyer will want to know how.

The sister topic is our guide on a tenanted property, where landlords also need to show that open fires and stoves are safe to use before a tenancy starts, so read that if you're letting.

How often should a stove be swept, and does it affect the sale?

HETAS says to sweep a chimney at least twice a year if you burn wood and at least once a year for smokeless fuel, and to have the appliance serviced at least once a year. A buyer's solicitor will rarely demand two years of receipts, but one recent sweep certificate dated within the past few months is the sweet spot.

If you've not swept it recently, do it before you list, not after. A freshly swept flue lets you honestly say "swept on [date]" on the property information form, which is a small sentence with a large calming effect on a nervous buyer.

Will my home insurer or the buyer's insurer care?

They can. Insurers commonly expect wood burners to have been fitted to building regulation standards, and an unapproved installation can complicate a claim after a chimney fire. For a buyer, that means the question isn't only "is it legal?" but "can I insure it?" That is another reason the certificate matters, and why buyers' solicitors ask for it.

If you're a seller, you aren't responsible for the buyer's insurance, but a buyer who can't get cover will wobble, and wobbles cost you time. Our guide to how to sell a house fast deals with that kind of delay in more detail.

Can a missing stove certificate stop a mortgage?

It can slow one down. Lenders' conveyancers need to satisfy themselves that nothing about the property threatens the security. Unregulated solid fuel installations sit on their checklist. In practice, if a certificate is missing, the buyer's solicitor reports it to the lender, and the lender asks for an indemnity policy, a regularisation certificate or an engineer's report. Most of the time the issue is solved. It adds days or weeks, though, and weeks are what lose sales to chain collapses. Our guide to cash house buyers explains the alternative if you'd rather skip lender-led conveyancing.

Cash buyer or open market: how does a stove change the route?

A cash buyer won't have a mortgage lender asking for certificates, so a missing stove certificate is less likely to hold up the transaction. That doesn't remove the risk. The buyer still has a solicitor, still checks, and may still knock something off the price for an unverified flue.

If speed matters more than squeezing the last pound, comparing offers is sensible. Our comparison of house buying companies shows how to separate the credible firms from the rest, and our piece on below-market-value offers explains what discounts are normal and what are not.

What should I do before listing a house with a stove?

This is the practical checklist I'd give a friend.

1. Find the certificate or completion certificate. Scan it and put it in your sale folder.
2. Locate the stove manual and data plate details. Photograph the plate.
3. Check if you are in a smoke control area. Note whether the stove is Defra-exempt.
4. Book a sweep and keep the receipt.
5. Test or replace the carbon monoxide alarm.
6. Have the hearth, flue and surrounding walls looked at for any visible damage.
7. If something is missing, decide between regularisation and indemnity before the buyer asks.
8. Fill in the TA6 accurately, with dates and names, and attach copies.

That's an afternoon of admin and maybe a couple of hundred pounds. Do it once and your solicitor can answer any enquiry in a single email.

What if the stove is in an inherited or probate property?

This catches executors out. You inherit a house with a stove, nobody knows who fitted it, and the previous owner is not around to ask. The same rules apply, but your best evidence is likely to be the deceased's papers, old invoices, or the council's building control file. If nothing turns up, an inspection plus indemnity cover is a reasonable approach. Our guide to selling inherited property covers the wider process, and the rule I'd stress is: do not fire the stove up for staging until a competent person has checked the flue, since you will own the consequences if something goes wrong.

What if I'm selling a flat or a leasehold property with a stove?

In a flat, a stove introduces extra questions. Does the lease permit a solid fuel appliance? Is the chimney demised to you or part of the common structure? Has the freeholder or management company consented? If the lease is silent, ask the managing agent, because a flue that serves several flats isn't yours to alter. In many blocks stoves are simply prohibited. Check before you advertise one. Our guide to selling a flat quickly goes through the other leasehold pack items a buyer's solicitor requests.

Are electric and gas stoves treated differently?

Yes. Electric stoves have no flue, so no Part J issue, though the wiring still needs to be safe. Gas fires and gas stoves must be installed by a Gas Safe registered engineer, and you'll have a different certificate. Bioethanol burners usually need no flue at all but do carry their own ventilation and fire safety rules. None involve HETAS. If your listing says "log burner" and it's actually a gas stove with a log-effect front, say so honestly, because the legal paperwork differs.

What mistakes do sellers make with stoves?

• Assuming the stove "came with the house" so it isn't their problem. It is your problem the moment you answer the property information form.
• Burning unseasoned wood in a viewing week. Smoke, smell and a sooty glass door put buyers off. Burn dry, Ready to Burn fuel, which Woodsure certifies for common wood fuels.
• Using a cousin's installer. If they aren't registered with a competent person scheme, the job needs separate building control notification.
• Leaving a cracked glass door or crumbling fire cement. A cheap fix that looks like neglect if left.
• Not telling the buyer the stove isn't allowed to burn logs in an SCA. That's the surprise that becomes a retrade.

How do I present a stove to add value?

Clean the glass, brush the hearth, stack a small neat pile of dry logs (not a mountain), and place the certificate and sweep receipt in a folder in the kitchen. Photograph it unlit, in daylight. A stove in a clean fireplace with documents to hand says "this house has been looked after", which is worth more than the stove itself. I'd rather a seller show me a folder than a fire.

Listing wording matters too. "Log burner (HETAS installed, 2021, swept September 2026)" is a lot stronger than "cosy log burner". Specific beats cosy.

Should I sell the stove separately or leave it?

Decide this early and write it into the contract inventory. The TA10 Fittings and Contents Form lets you say whether the stove, hearth accessories and flue pipe stay. A stove is normally treated as a fixture if it's plumbed into a flue, so assume it stays unless you have specifically excluded it. If you plan to take it, say so, and agree in writing how the chimney will be left (capped, blanked, made safe). Taking a stove and leaving a gaping flue is the quickest way to start a row at completion.

What does it cost to fix a stove problem before selling?

Costs vary by region and by what the engineer finds, so I won't pretend there is one number. The categories are what matters. A chimney sweep is a modest spend. A HETAS engineer inspection is a bigger one. A regularisation application carries a council fee. A CCTV flue inspection or a new liner is the substantial item, and it's the one you want to find before the buyer's surveyor does. Get two or three quotes, and compare the cost to a price reduction the buyer might ask for. In my experience the buyer's figure is always higher than the seller's fix.

When does a stove make a house hard to sell?

Occasionally a stove problem is the visible tip of something bigger: a cracked chimney stack, a damp-stained breast, a flue running through a roof void with no protection, or a stove in a property with a thatched roof, where installation rules are much tighter. When there are structural questions on top of missing paperwork, a conventional buyer's lender may walk away. That's when a specialist or cash buyer becomes the practical route. Read our piece on selling a house nobody will mortgage before you accept a lowball.

Which questions do buyers ask about stoves most?

Having sat across from plenty of buyers and sellers, I'd say the same handful come up: Who installed it? Is there a certificate? When was it swept? Does it burn wood in this area? Does my insurer need to know? If you can answer those five without hunting through drawers, the stove is a plus. If you can't, it becomes a negotiating point.

Where does Ready Steady Sell fit in?

If your stove paperwork is a mess, the house has other issues, or you simply don't want a three-month wait for a mortgage-dependent buyer, comparing offers is worth ten minutes of your time. Start a valuation here, see what is on offer, and decide with real numbers in front of you. There's no obligation, and you stay in control of which, if any, you accept.
