Survey finding
Solid fuel heating: what UK buyers should check
Wood-burning stoves and other solid-fuel heating are common in rural and period properties. This page covers HETAS certification, Smoke Control rules, and what the survey should confirm.

Finding
Solid fuel heating
What this usually means
Solid-fuel heating includes wood-burning stoves, multi-fuel stoves, biomass boilers, and (rarely now) coal-fired open fires and back boilers. Modern HETAS-installed stoves are well documented and safe; older installations may lack the carbon monoxide alarms, ventilation, or chimney lining required by current Building Regulations. Smoke Control Area rules (most UK urban areas) restrict what can be burned.
Why it matters
Solid fuel is not a defect but carries CO and chimney-fire risks if poorly installed or maintained. Building Regulations Part J covers combustion appliances and flues, non-compliant installations are flagged at survey. Lender appetite is standard if HETAS-certified.
Ask your surveyor
- Check:Is the appliance HETAS-certified, and is the certificate available?
- Check:Is the flue lined and the lining of the right specification?
Ask the seller
- Check:When was the appliance installed and is the HETAS certificate available?
- Check:When was the chimney last swept and is there a sweep certificate?
Next steps
- •Get two written quotes from local trades before negotiating with the seller.
- •Speak to your mortgage broker before exchanging if the finding affects mortgageability.

What you need to know
Severity
Maintenance item. Worth quoting and including in negotiation.
Typical cost to fix
HETAS-certified wood-burning stove install: £1,500–£3,500. Chimney lining as part of stove install: £700–£1,500. Carbon monoxide alarm: £15–£40 per unit. Compliance retro-fit if existing install is non-compliant: £400–£1,500.
Mortgage impact
Standard for most lenders if installation is HETAS-certified and CO alarms are in place. Non-compliant installations may trigger a retention until certified.
Insurance impact
Standard insurance covers solid-fuel heating if installation meets Building Regulations and is regularly serviced. Some insurers ask whether the stove is in active use.
When to pull out
Almost never a pull-out trigger.
When to renegotiate, and by how much
If the installation is non-compliant, ask the seller to obtain HETAS certification or fund the retrofit. Not a price-renegotiation item.
