The average cost for a house extension in Coventry ranges from £1,200 to £2,000 per square meter in 2026. This price can vary based on the type of extension and the materials used. For instance, a single-storey extension may cost around £15,000 to £30,000, while a double-storey extension can go from £30,000 to £60,000.

It's important to hire registered professionals, especially those who are Part P certified for electrical work and Gas Safe registered for any gas installations. Look for builders with good local reputations and check their previous work in your area. Coventry has several experienced builders who can help you navigate the planning permissions and building regulations specific to the West Midlands.

Keep in mind, these costs may also include additional fees such as architect fees (around £1,500 to £3,000) and council application fees. Getting multiple quotes from local builders can help you find the best deal.
