In Hatfield, the cost of a house extension in 2026 typically ranges from £1,500 to £2,500 per square meter. Several factors influence the final price, including the type of extension, materials used, and the complexity of the build. For a single-storey extension, you might expect to pay around £20,000 to £40,000, while a double-storey extension could cost between £40,000 and £80,000. It's important to ensure that any builder you consider is registered with relevant certifications, such as being a member of the Federation of Master Builders (FMB) or having UKAS-accredited qualifications. This ensures that they meet high standards in quality and safety. Additionally, check that they are familiar with local planning regulations in Hatfield to avoid any issues.
