What customers say — Welwyn & nearby
★★★★★ 4.9 / 5 from verified customers
★★★★☆

“Used this to find a specialist for a Velux conversion. Took a couple of days to get all three quotes back but they were all competitive. Work was completed in three and a half weeks and the new loft room has made a huge difference to the house. Very pleased overall.”

Marcus L. Welwyn
★★★★★

“We had a rear dormer conversion done last summer — extra bedroom and en-suite for our teenage daughter. Got three quotes through this site, saved around £4,000 compared to the first firm we spoke to. The specialist handled planning permission and building regs start to finish. Highly recommend.”

Sarah M. Surrey
★★★★★

“Hip-to-gable conversion on our 1930s semi. I was nervous about the planning application but the specialist I found here had done dozens in our street and knew exactly what to submit. Project came in on time at 10 weeks. The new master bedroom is brilliant.”
