Q: What's the average cost of installing a log burner?

The average cost of installing a log burner sits around £1,500 to £2,500 when you include the stove, flue liner, hearth, and labour, though simple jobs using an existing chimney can come in lower and complex retrofits can run higher. Costs are driven mainly by whether a chimney already exists, the length and type of flue liner needed, and any preparatory building work. It's worth getting a fixed quote rather than relying on averages, since every property and chimney setup is different. A site visit lets an installer give you a realistic figure rather than a rough guide.

Q: How much does it cost to install a wood burning stove?

The cost to install a wood burning stove generally falls between £1,000 and £3,500, depending on whether you're using an existing chimney or need a full flue system fitted from scratch. Stove price itself is separate from installation labour and materials, so the two should always be quoted individually so you can see where your money is going. Older properties with non-standard chimneys or listed building constraints can push costs toward the higher end. A HETAS-registered installer will factor in your specific chimney condition and property type when pricing the job.

Q: How much does a twin wall flue system cost?

A twin wall flue system typically costs between £800 and £2,000 depending on the height required, the number of bends, and whether it runs internally or externally up the outside of the property. Twin wall flues are commonly used where a property has no existing masonry chimney, offering a compliant route to safely vent a stove through a wall or roof. Material costs form part of the overall price, but professional installation is essential to ensure the correct clearances and weatherproofing are achieved. Always get a fixed quote for the full twin wall flue installation rather than relying on material costs alone.

Q: What affects the cost of twin wall flue installation?

Twin wall flue installation cost is affected mainly by the total height of run needed, the number of directional bends, and whether the flue exits through an existing roof, a wall, or needs full external bracketing up the side of a building. Access difficulty, such as installations on multi-storey properties or awkward roof lines, can also add to labour costs. Because a twin wall flue is a Class 1 chimney alternative, it must be installed to strict clearance and support standards, which is not a task suited to DIY. A HETAS-registered installer can survey your property and provide an accurate cost breakdown for your specific flue run.
