How these calculators work. Each one combines a base range from published UK trade pricing data (manufacturer RRPs, FMB/HomeOwners Alliance / NICEIC installer rate references) with project-specific modifiers. The output is an indicative range, your actual price will depend on your home, location, and the tradesperson's day rate. Always get 3 written quotes from accredited businesses.
