Frequently Asked Questions — Concrete in United Kingdom

How much does concrete cost per cubic metre in the UK?▼

In the UK, ready-mix concrete costs £85-£130 per cubic metre for standard grades (C20-C30). London and Southeast prices are 15-25% higher at £110-£150/m³. Delivery charges apply, typically £150-£250 per load. Part-load surcharges add £15-£30/m³ for orders under 4m³.

What concrete grade should I use for a house foundation in the UK?▼

For UK house foundations (strip and trench fill), use C25 grade concrete minimum, as specified in BS 8500. For deeper foundations or aggressive soil conditions (sulfate-bearing), use C30 or higher with appropriate sulfate-resistant cement (SRPC).

How do I calculate concrete in metric?▼

Multiply length × width × depth in metres to get cubic metres (m³). Example: A 6m × 4m patio at 100mm (0.1m) thick = 6 × 4 × 0.1 = 2.4m³. Add 10% for waste = 2.64m³. Round up to the nearest 0.5m³ for ordering.

Do I need planning permission for a concrete slab in the UK?▼

Generally, you don't need planning permission for a concrete slab in your garden (permitted development). However, you may need it if: the area exceeds 50% of your garden, it's in a conservation area, or it involves significant changes to drainage. Always check with your local planning authority.

What is the cheapest month to pour concrete in the UK?▼

Concrete prices in the UK are most competitive during winter months (November-February) when demand is lower. However, you may need frost protection measures. The best value-for-money is typically March-April and September-October — good weather with moderate demand.
