In Hatfield, the average costs for building services such as house extensions, loft conversions, and garage conversions can vary significantly based on specifications and local labour rates.

### House Extensions For a single-storey extension, you can expect to pay around £1,200 to £1,500 per square metre. Therefore, a typical 20 sqm extension could cost between £24,000 and £30,000.

### Loft Conversions Loft conversions tend to range from £30,000 to £50,000, depending on whether you’re opting for a dormer, hip-to-gable, or a simple roof light conversion. This price includes necessary structural changes and finishes.

### Garage Conversions Converting a garage into a living space can cost about £10,000 to £20,000. This price may vary based on insulation, utilities, and fixtures.

It’s crucial to hire professionals with appropriate certifications, such as NICEIC for electrical work and Gas Safe registration for any gas installations. Ensuring your builders are vetted and certified guarantees quality and compliance with local regulations.
