Frequently Asked Questions
The current RICS building cost per square metre for a standard specification house in early 2026 ranges from £1,650 to £1,950/m² nationally, with London and Southeast typically 20-25% higher at £2,000-£2,400/m².
London building costs are typically 20-25% above national averages. The premium is driven by higher labour costs (30-40% more), land prices, site constraints, and London-weighted salary supplements for construction professionals.
Standard RICS building costs per m² typically exclude VAT (20%), professional fees (10-15% of build cost), planning fees, and land purchase. They represent the pure construction cost including materials, labour, and contractor overheads.
RICS publishes formal updates quarterly, but significant market changes may trigger interim updates. The 2026 Q1 data reflects stabilisation after previous volatility, with annual increases now projected at 3-4% for the year.
For 2026 projects, we recommend 10-15% contingency for standard projects and 15-20% for complex or renovation projects. This accounts for design changes, unforeseen ground conditions, and potential material price fluctuations.
Yes, self-builders typically achieve 15-25% savings compared to developer costs by eliminating developer profit margins, managing their own project, and making different specification choices, though this requires significant time commitment.
Sustainable features typically add 5-15% to base construction costs in 2026. However, they often provide long-term savings through reduced energy bills and may qualify for green financing incentives with better interest rates.
