UK Construction Inflation Calculator
What Would That Cost Today?
Sense-check an old project cost against today’s money. This calculator uses UK CPI data to adjust historic figures, so you can compare past quotes, budgets, and allowances without treating CPI as a full construction cost index.
- Based on official ONS CPI (2015 = 100).
- Tracks general inflation – not build-specific prices.
- Handy for comparing old budgets or historic quotes.

FAQs
How accurate is this calculator?
It provides planning-grade guidance. For tenders, use a QS estimate with a BoQ and clear clarifications and assumptions.
Which inflation index does it use?
We align to publicly available UK CPI benchmarks and review inputs periodically. CPI tracks general inflation, not sector-specific construction indices.
Do results include VAT?
Figures are shown net of VAT unless stated. Add VAT if you are pricing consumer work.
