Absolute cowboys. I'd give zero stars if possible. Exorbitant fees but i did know these at outset as i was desperate. Their 'technician' was in and out 15 mins and said he'd sorted it by simply unscrewing and re-screwing the pipes. He was more concerned with getting out asap (it was xmas eve). He did not fix the issue and on coming out again said it would cost another £176 plus parts to have another ago. I called s0meone else out who changed the value over in 30 mins for £50. Plumbing force refuse to address their awful service. Definite 'rogue traders' so just be on your guard.
