The cost of log burner installation in the UK can vary depending on your property, chimney condition, stove type, flue requirements, and the amount of building work needed.
As a general guide, a full professional log burner installation can cost anywhere from £1,500 to £5,500+.
A simple installation using an existing fireplace and suitable chimney will usually cost less. A more complex installation with a new flue system, chimney work, hearth construction, or fireplace alterations will cost more.

Log Burner Installation Cost Breakdown
1. Cost of the Log Burner
The stove itself can cost around £500 to £2,500+, depending on the brand, size, design, efficiency rating, and whether it is DEFRA-approved or Ecodesign compliant.
A small 5kW stove is usually more affordable than a larger feature stove or premium designer model.
2. Flue Liner Cost
Many UK homes need a flue liner when installing a log burner. A flue liner helps carry smoke and gases safely out of the property and can improve chimney performance.
A flexible stainless steel flue liner installation can commonly cost around £800 to £1,800, depending on chimney height, liner grade, access, and labour.
If your chimney is damaged or unsuitable, extra repair work may be needed.
3. Labour Cost
Professional installation labour can cost around £500 to £1,500, depending on the complexity of the job.
Labour may be higher if the installer needs to:
- Work at height
- Use scaffolding
- Remove an old fireplace
- Open up a chimney breast
- Install a new hearth
- Fit a new flue system
- Carry out extra safety checks
A simple stove replacement will usually be cheaper than a full new installation.
4. Hearth Installation Cost
A log burner needs a suitable hearth to protect the floor and surrounding area.
A basic hearth may cost a few hundred pounds, while a custom stone, slate, or tiled hearth can cost more.
Typical hearth costs can range from £300 to £1,200+, depending on material, size, and finish.
5. Chimney Sweeping and Inspection
Before installing a log burner, the chimney should usually be swept and inspected.
A chimney sweep helps remove soot, tar, debris, and old deposits before the flue liner or stove is fitted.
This can help the installer check the chimney condition properly and reduce the risk of problems after installation.
6. External Twin-Wall Flue Cost
If your home does not have a suitable chimney, you may need an external twin-wall flue system.
This is more expensive than using an existing chimney because the installer needs to create a safe flue route through the property and outside the building.
A twin-wall flue system can add £2,000 to £5,500+ to the project, depending on property layout, height, access, and materials.
7. Building Work and Fireplace Alterations
Some homes need additional building work before a log burner can be installed.
This may include:
- Removing an old fireplace
- Opening up a chimney breast
- Installing a new lintel
- Repairing brickwork
- Plastering
- Creating a stove chamber
- Adding a beam or surround
- Fitting a new hearth
This type of work can significantly increase the total installation cost.
Do You Need a HETAS Installer?
Using a HETAS registered installer is strongly recommended for log burner installation in the UK.
A HETAS registered installer can usually self-certify the work and provide a Certificate of Compliance. This shows that the installation has been completed in line with building regulations.
This certificate may be important for:
- Home insurance
- Future property sale
- Safety records
- Warranty requirements
- Building regulation compliance
If you do not use a competent person scheme installer, you may need to apply through local Building Control.
What Affects the Cost of Log Burner Installation?
The final cost can depend on:
- Whether you already have a chimney
- Chimney condition
- Whether a flue liner is needed
- Stove size and model
- Property height and roof access
- Hearth requirements
- Fireplace opening size
- Ventilation requirements
- Building work needed
- Your location in the UK
- Whether scaffolding is required
A proper home survey is the best way to get an accurate quote.
Is a Cheap Log Burner Installation Worth It?
A cheap installation may seem appealing, but log burner fitting is not an area where you should cut corners.
Poor installation can lead to:
- Smoke entering the room
- Poor stove performance
- Carbon monoxide risks
- Chimney leaks
- Fire hazards
- Failed building control checks
- Insurance problems
Always make sure the installer is qualified, experienced, and able to provide the correct certification.
Can You Install a Log Burner Yourself?
DIY installation is possible in some cases, but it is not recommended for most homeowners.
A log burner installation must meet building regulations, manufacturer instructions, ventilation requirements, flue safety rules, and carbon monoxide safety guidance.
If the work is not carried out by a registered competent person, Building Control approval may be required.
For safety and compliance, it is usually best to hire a qualified professional.

- Is the hearth included?
- Is certification included?
- Will a carbon monoxide alarm be fitted?

Final Answer: How Much Does Log Burner Installation Cost in the UK?
Log burner installation in the UK usually costs between £1,500 and £5,500+, depending on the property and the work required.
A straightforward installation with an existing chimney will usually be more affordable. A full installation with a new flue liner, hearth, stove, building work, and certification will cost more. If your home needs an external twin-wall flue system, the price can increase significantly.
The best way to know the exact cost is to book a chimney inspection and installation survey.
