How accurate is this building cost calculator?
It gives a realistic guide range based on typical 2026 UK cost-per-square-metre rates for each project type and specification level. Every project is different — ground conditions, access, structural work and finishes all affect the final figure — so treat it as a starting point and request a free, itemised survey for an accurate, fixed quote.
What does the estimate include and exclude?
The estimate reflects typical build costs (labour and materials) for the work itself. It generally excludes VAT, professional and planning fees, structural engineer costs, and a recommended 10–15% contingency. We spell all of this out in a detailed written quote.
Why is there a range rather than a single price?
Building costs vary with specification (standard, mid-range or premium finishes), size, and site-specific factors. The range shows the realistic spread so you can budget sensibly — then we firm it up after a site visit.
Can you give me an exact quote?
Yes. Once you have a ballpark from the calculator, request a free, no-obligation survey and we'll provide a detailed, itemised, fixed quote for your specific project across Shrewsbury, Shropshire and the wider Midlands.
