The average cost for a house extension in Paisley typically ranges from £1,500 to £2,500 per square metre in 2026. This means a standard extension of around 20 square metres could cost between £30,000 and £50,000, depending on materials and design complexity. It’s essential to hire certified professionals for such projects; look for builders who are registered with the Federation of Master Builders (FMB) or have NICEIC certification if electrical work is involved.

## Additional Costs Don’t forget to budget for additional expenses like planning permission fees, which can be around £200, and any necessary structural assessments. Also, if you're planning a loft conversion or garage conversion, costs can vary, generally falling between £20,000 and £40,000 depending on the project's scale and specifications.

It’s advisable to obtain a few quotes from local builders to ensure you’re getting a fair price and quality service.
