How Much Does It Cost to Install a Log Burner in 2026?

Installing a log burner is one of the most rewarding home upgrades you can make, but working out the true cost can feel like a guessing game. The price of the stove itself is only part of the picture; flue work, professional fitting, hearth preparation and building control sign-off all add up. In this guide we break down realistic UK figures for 2026, separate the two main installation scenarios, and explain why getting two or three quotes from HETAS registered installers is the smartest move you can make.

The Two Main Installation Scenarios

Before looking at numbers, it helps to understand that your total cost depends heavily on whether your home already has a chimney. The two routes are very different in scope and price.

Fitting into an existing chimney

If you have a sound masonry chimney, your installer will usually fit a stainless steel chimney liner down the existing flue. This is the cheaper and quicker route, typically pushing total costs towards the lower end of the range.

Installing a twin-wall flue in a chimney-less home

If you have no chimney, you will need a twin-wall flue system routed vertically through the roof or up an external wall. This involves more materials, more labour and often scaffolding, so it sits firmly at the higher end of the budget.

Cost of the Stove Itself

The appliance is your starting point. Modern stoves must meet Ecodesign 2022 standards, and if you live in a smoke control area you should look for a DEFRA exempt model. Prices vary by size, output and brand.

• Entry-level Ecodesign stoves: around £500 to £900
• Mid-range branded stoves: £900 to £1,800
• Premium and contemporary designs: £1,800 to £3,000 or more

You can browse a wide selection of wood burning stoves to compare outputs and styles. Remember that Burner Hub charges a flat £100 UK delivery on stove orders, which you should factor into your overall budget.

Flue and Chimney Costs

This is where the two scenarios diverge most. A chimney liner is far less involved than a full twin-wall flue run.

• Chimney lining for an existing chimney: roughly £500 to £1,500 including the flexible liner, fittings and labour
• Twin-wall flue system for a chimney-less home: roughly £1,200 to £3,000 depending on the height of the run, whether it goes internal or external, and access

External twin-wall runs and multi-storey routes cost more because of additional brackets, fire stops and weatherproofing. If scaffolding is required, expect that to add several hundred pounds.

Installer Fees, Hearth and Safety Items

Professional fitting is essential for safety and compliance. A HETAS registered installer can self-certify the work, saving you a separate building control application.

Labour

HETAS installer fees generally fall between £800 and £2,500, depending on complexity, region and how much building work is involved. Cutting a new opening or removing an old fireplace pushes this higher.

Hearth and surround

You will need a compliant hearth to protect the floor. A simple slate or glass hearth might cost £100 to £400, while a bespoke stone surround can run to several hundred pounds more.

Carbon monoxide alarm and sign-off

Building Regulations require a carbon monoxide alarm in the room, typically £20 to £50. Building control sign-off is included when a HETAS installer self-certifies; if a non-registered fitter does the work you must notify building control separately, usually costing £150 to £400.

Full Cost Breakdown Table

The table below summarises the typical 2026 ranges for each element across both installation scenarios.

Item	Existing Chimney	Chimney-less (Twin-Wall)
Stove purchase	£500 to £3,000+	£500 to £3,000+
Flue or liner	£500 to £1,500	£1,200 to £3,000
HETAS installer fees	£800 to £1,800	£1,200 to £2,500
Hearth and surround	£100 to £600	£100 to £600
Carbon monoxide alarm	£20 to £50	£20 to £50
Delivery	£100 flat	£100 flat
Typical total	£2,000 to £4,000	£3,500 to £6,000+

What Affects the Final Price?

Two homes can receive very different quotes for what looks like the same job. The main variables include:

1. Region: labour rates in London and the South East are often higher than in the North or Scotland
2. Complexity: awkward access, tall flue runs and structural work all add cost
3. Stove type: contemporary and larger output models cost more than compact traditional stoves
4. Condition of the chimney: repairs or sweeping before lining can add to the bill
5. Extras: log stores, fans, decorative beams and plastering work

How to Get the Best Value

The single best thing you can do is obtain two or three written quotes from HETAS registered installers. This lets you compare not just price but the scope of work, the materials specified and the warranty offered. Ask each installer to itemise the stove, flue, labour, hearth and any building work separately so you can see exactly where your money is going. A cheap quote that omits a proper liner or skips building control compliance is no bargain. Buying your stove from a reputable retailer and arranging fitting with a local HETAS professional often gives you the best balance of choice and value.

With realistic budgeting and the right professional support, a log burner remains an excellent long-term investment in warmth, efficiency and the character of your home.

Frequently asked questions

How much does it cost to install a log burner in 2026?

In 2026, most UK homeowners spend between £2,000 and £6,000 in total. Fitting a stove into an existing chimney sits at the lower end, while a twin-wall flue in a chimney-less home reaches the higher end. The figure includes the stove, flue or liner, HETAS labour, hearth and a carbon monoxide alarm. Browse our wood burning stoves to start estimating your own budget and remember to add the £100 flat UK delivery charge.

Do I need a HETAS installer to fit a log burner?

You do not legally have to use a HETAS installer, but it is strongly recommended. A HETAS registered installer can self-certify the work, meaning building control sign-off is included without a separate application. If you use a non-registered fitter, you must notify building control yourself, which typically costs £150 to £400. HETAS fitting also protects your stove warranty and ensures the installation meets current Building Regulations and safety standards.

Can I install a log burner without a chimney?

Yes. Homes without a chimney use a twin-wall insulated flue system routed vertically through the roof or up an external wall. This is more involved than lining an existing chimney, so costs are higher, typically £1,200 to £3,000 for the flue alone. Many of our wood burning stoves are suitable for twin-wall installs, but always confirm compatibility with your HETAS installer before purchasing.

Why is chimney lining recommended for a log burner?

A stainless steel chimney liner ensures the flue gases vent safely and improves the draw of your stove, helping it burn efficiently. Older masonry chimneys can be porous, cracked or oversized, which reduces performance and increases the risk of leaks. Lining typically costs £500 to £1,500 including labour. Your installer will inspect and sweep the chimney first, and any repairs needed before lining may add to the overall cost.

Should I get more than one installation quote?

Absolutely. We recommend obtaining two or three written quotes from HETAS registered installers so you can compare price, scope and materials. Ask each one to itemise the stove, flue, labour, hearth and any building work. This makes it easy to spot a quote that cuts corners, such as omitting a proper liner. Comparing quotes is the simplest way to secure fair pricing and a compliant, safe installation.
