Important Disclosures
These calculators produce planning estimates only.
They do not constitute structural, building, gas, or electrical advice,
nor a certificate of Building Regulations compliance. Results are
derived from your inputs and UK trade defaults — they do not
account for site conditions, regional pricing, supplier minimums,
or unique construction constraints.
BuildMetricLab is a planning aid. We are not chartered engineers,
architects, or Building Control surveyors. For structural, gas,
electrical, drainage, or Building Regulations matters, consult
a suitably qualified professional — a Gas Safe registered
engineer, NICEIC-approved electrician, or chartered structural
engineer as applicable — before committing to work.
