Southwark Homeowners Trust BestBuilders
Loft dormer en-suite in Southwark, London. Bath out, walk-in tray fitted, glass screen, new electric shower with pump. ยฃ9125 all-in, took 11 days. CIPHE-credentialed plumber, all isolation valves accessible behind a removable panel. Best home improvement decision we have made in years.
Used BestBuilders to find a bathroom fitter near Southwark. Three responses, all from fitters within 5 miles of Southwark, picked the quote that included scaffolding rather than charging extra. Demolition Monday, first-fix Tuesday-Wednesday, second-fix Thursday-Friday, tiling the next week. Insurance happy with the test certificates.
Five months later, the extractor fan with humidity sensor stops the steam before it can settle. Honoured the 12-month workmanship guarantee on a single tile crack at month 9. Already used the fitter for a friend in Southwark.
