Frequently Asked Questions
How much does a concrete slab cost per m² in the UK?
A basic concrete slab in the UK costs £60–£120 per m² installed. Premium finishes such as exposed aggregate or coloured concrete can add £30–£60/m² on top.
Do I need planning permission for a concrete slab in the UK?
For most garden patios and paths, planning permission is not required. However, impermeable driveways over 5m² at the front of a property may require permeable paving or drainage — check with your local authority.
How long does a concrete slab last in the UK?
A well-laid concrete slab can last 30–50 years with minimal maintenance. The UK's freeze-thaw cycle can cause surface cracking over time — using air-entrained concrete and proper drainage significantly extends its lifespan.
