The cost to install a wood burning fireplace generally ranges from £1,500 to £4,000, depending on whether you’re fitting into an existing fireplace opening or creating a new one, plus any flue or chimney work required. Retrofitting into an existing, well-maintained fireplace opening tends to sit at the lower end of this range, while properties needing a new flue liner or structural opening work cost more. Location within the home also matters — installations in garages or conservatories can involve additional flue routing considerations compared with a traditional lounge fireplace. A HETAS-registered installer will need to see the space in person to give you a firm cost to install a wood burning fireplace.
