Request a Professional EstimateHow We Calculate Volume
Volume is calculated using the standard geometric formula for each element type. Slab and wall volumes use length × width/height × depth. Column volumes use π × r² × height. All results include a 5% standard waste factor.
UK Concrete Pricing
Ready-mix concrete prices in the UK typically range from £90 to £160 per m³ depending on grade (C20 to C40), admixtures, regional location, and order volume. Our calculator uses £135/m³ as a midrange guide.
Why Use a Professional Estimator?
While our calculator gives a useful indicative figure, professional estimates account for reinforcement, formwork, access, labour, plant, specification compliance, and current supplier pricing — all critical for tender accuracy.
