In Milton Keynes, the cost of a house extension typically ranges from £1,500 to £2,500 per square metre in 2026. For a standard 20 square metre extension, you can expect to pay around £30,000 to £50,000. Factors affecting the price include design complexity, materials used, and local council regulations. Extensions often require Planning Permission and Building Regulations approval, so it's crucial to choose builders who are familiar with the local processes.

Make sure to hire certified professionals, ideally those registered with the Federation of Master Builders (FMB) or NICEIC, to ensure quality workmanship and compliance with safety standards. Additionally, consider obtaining quotes from several local builders to compare costs and services.

If you're searching for quality building services, look for those who have a strong portfolio of previous work in the Milton Keynes area.
