How much does a home extension cost in Grimsby?

A typical Grimsby home extension works out at about £18,000–£63,000 in 2025. Yorkshire costs are generally among the lower in the UK — Lincolnshire labour and materials are a real factor. Expect single vs double storey and floor area and planning, glazing and finish quality to move the price most, along with foundations and structural work. Getting two or three quotes is the best way to see a fair local price, which is exactly what our free matching service arranges.
