Portsmouth Homeowners Trust BestBuilders
Cloakroom WC fit-out in Portsmouth, Southern. New first-fix copper, isolation valves at every fitting, heated towel rail loop. Quote of £10500 held to the penny. NICEIC Part P signed off the new lighting circuit and shaver socket. No callbacks needed - sealed properly first time.
Used BestBuilders to find a bathroom fitter near Portsmouth. Five firms quoted, narrowed it to two on detail, chose on the strength of the existing reference jobs we visited. Used a temporary basin and shower rig in the utility - never went a day without washing. Three months on, still nothing to fault.
Four months in and the porcelain tile finish has not chipped, marked or moved at all. Six-month follow-up call to ask if anything needed adjustment - nothing did. EPC went up one band thanks to the new heated towel rail being on a timer.
