In Mill Hill, the average price for building services varies significantly based on the type of project. For a house extension, you can expect to pay around £1,500 to £2,500 per square metre. Therefore, a typical 20 square metre extension could cost between £30,000 and £50,000.

For a loft conversion, which often requires planning permission and structural alterations, prices range from £20,000 to £50,000, depending on the complexity and the size of the space. On the other hand, a garage conversion tends to be more economical, averaging £10,000 to £20,000.

It's essential to hire professionals certified by relevant bodies, such as NICEIC for electrical work and Gas Safe for any gas-related installations. These certifications ensure safety and compliance with local regulations, which is crucial for maintaining the integrity of your home.

Overall, budget planning is vital, and it's advisable to get multiple quotes to compare services offered.
