How to DIY building in Hayes?

DIY building projects like house extensions, loft conversions, or garage conversions can be rewarding but require careful planning and execution. Firstly, check local regulations and obtain necessary permissions from the London Borough of Hillingdon. For small extensions, you may be able to use permitted development rights, but larger projects might need full planning permission.

Next, create a comprehensive budget. In 2026, expect to spend approximately £12,000–£20,000 for a basic loft conversion, while garage conversions can range from £8,000–£15,000. Include costs for materials, tools, and possible hiring of professionals for specific tasks. Remember, for structural work and electrical installations, you'll need certified tradespeople. Look for contractors registered with NICEIC for electrical work and Gas Safe for any gas installations to ensure safety and compliance.

Lastly, focus on quality workmanship, as this affects both aesthetics and resale value. Make sure to invest time in learning the necessary skills through online tutorials or local workshops.
