Wood Burning Stove Installation Costs Explained: What You're Really Paying For.

A clear, honest guide from Southwest Woodburners — plus how to save by supplying your own stove or flue and using your own fitter.

If you've spent any time searching "wood burning stove installation cost" you'll have found five different websites quoting five different numbers, anywhere from £1,500 to £8,000+. It's no wonder people find it confusing. This guide breaks down exactly what makes up the cost of a stove installation, and what you can expect to pay for a complete, professionally fitted job.

We install stoves across Dorchester and the South West, and for most customers a full supply-and-fit installation — handled start to finish by us — is the simplest, safest option. That said, we know some people already have a trusted fitter or prefer to source materials themselves, so we also supply stoves, flue liners and flue components on their own for anyone who wants to arrange the installation separately.

Why stove installation quotes vary so much

There's no single "cost of a wood burner." Every quote is really three separate costs bundled together:

1. The stove itself — the appliance you buy

2. The flue system — what safely carries smoke and gases out of your home

3. Labour and building work — fitting the stove, installing the flue, hearth work, and certification

Most of the confusion comes from company A quoting for a straightforward job into a good, existing chimney, while company B is quoting for a house with no chimney at all, or one that needs significant remedial work. Same headline — very different job.

Real costs, based on our own installations

Rather than give you vague industry averages, here are three real-world scenarios based on jobs we actually price and carry out. Installation figures are shown +VAT (as labour and materials are quoted), and stove prices are shown inc. VAT, since that's how they're sold. We've also given an approximate all-in total so you can see what a finished job actually looks like.

1. Flexible flue liner, using the existing chimney and hearth, with scaffolding for access

• Installation: around £2,200 + VAT (approx. £2,640 inc VAT)

• Stove: typically £1,600–£2,000 inc VAT

• All-in total: roughly £4,200–£4,650

This is the most straightforward and common job — an existing, usable chimney, a liner run down it, and the existing hearth reused. Scaffolding is often needed for safe access to the chimney pot, which is factored into the price above.

2. Twin wall flue, two-storey house, routed out through the wall and up externally

• Installation: around £4,000 + VAT (approx. £4,800 inc VAT)

• Stove: typically £1,600–£3,000 inc VAT, with premium stoves running up to around £3,800 inc VAT

• All-in total: roughly £6,400–£8,600 (or up to around £9,400 with a premium stove)

Twin wall systems cost more to install than a liner because there's more flue run, more brackets and weatherproofing, and often scaffolding for the external run up the wall. This is typically the route when there's no usable chimney and the flue needs to go up the outside of the property.

3. Twin wall flue, bungalow, routed straight up through the roof

• Installation: around £3,100 + VAT (approx. £3,720 inc VAT)

• Stove: typically £1,600–£3,000 inc VAT, again up to around £3,800 for premium models

• All-in total: roughly £5,300–£7,500

A shorter, more direct run through the roof of a single-storey property keeps this below the two-storey external twin wall job, though it's still a bigger job than a straightforward liner installation.

Why the range within each scenario? The installation cost is largely fixed once we know the route and access requirements — the variable is almost always the stove itself. Entry-level stoves, larger or higher-output stoves, and premium brands all sit at different price points, which is why we've given a range rather than one number.

These figures are based on typical jobs and give you a genuinely realistic starting point — but every property is different, so the only way to get an exact number for yours is a site visit.

Why "new stove, new liner" is usually the rule

Every installation we carry out follows Building Control guidance: a new stove generally means a new flue liner. For flexible flue liners running inside an existing brick chimney, this is straightforward and it's a rule that exists for good reason — an old liner may not be rated for the temperatures or flue gases a new stove produces, and reusing an unknown liner is a false economy if it fails inspection or, worse, in service.

Some existing twin wall flue systems can be connected to rather than replaced — but only where we can confirm they're compatible. This is where things get more complicated than most people expect.

Why you almost can't reuse an existing twin wall system

Twin wall flue is not a generic, one-size-fits-all product. Every manufacturer's system uses its own connecting components, seals and fixings, and these are very rarely interchangeable between brands — even when two systems look similar from the outside.

In practice, most homeowners don't know what manufacturer or system is already installed in their property. Without that information, we can't confirm compatibility, and fitting mismatched components isn't something we — or any responsible installer — will do, because it compromises the safety of the whole system. This is why, in the vast majority of cases, an existing twin wall system ends up being replaced rather than connected to, even though in theory a compatible connection is possible. If you do have documentation, a data plate, or a manufacturer's name for your existing twin wall system, it's worth digging it out before you get quotes — it could save you money.

Getting an accurate cost for your own installation

Because chimney condition and flue route make such a difference, the best way to get a real number is a site visit — over the phone or from a photo, we can only ever give you a ballpark. If you're near Dorchester or anywhere across the South West, we're happy to come and take a look, talk through your options honestly, and give you a proper breakdown of stove, flue and labour costs separately — so you can decide exactly how much of the job you want us to do.

Frequently asked questions

Do I always need a new flue liner with a new stove? In the vast majority of cases, yes — this follows Building Control guidance and ensures the flue is properly rated for your new appliance. It's one of the checks made as standard on every installation we carry out.

Can I reuse my existing twin wall flue system? Sometimes, but only if we can confirm it's compatible with the stove and connecting components you're using. Because most homeowners don't know the manufacturer of their existing system, and components generally aren't interchangeable between brands, replacement is usually the safer and more practical route.

Can I just buy a stove from you without installation? Yes. We supply stoves, flue liners and flue components on their own, for customers arranging their own installation or using their own fitter.

Do you have stoves in stock I can take away immediately? We're actively building up a range of stock stoves that are ready to take away without waiting for a lead time — get in touch to see current availability.
