Home improvement prices
Guide ranges for every service, with three options each. Your fixed price follows a free survey.
How to read these prices
These are guide ranges for typical West Midlands homes in 2026, shown as the total you'd expect to pay, including VAT where it applies. They come from the same rates we quote from, but every house is different — your fixed price follows a free survey and is set out in writing, itemised, before you agree to anything.
The option marked “Recommended” is the one we usually suggest for a typical home. Use the guide-price tool for a range based on your answers.
