On their website states they will quote first. On the phone they said £50 call out charge, and that the plumber would let me know how much it would be before he did any work as it would depend on materials used. Plumber didn't give us a quote before he started work, but said he just needed to use plumbers tape and tighten some bolts. 10 minutes later the job is done and I'm told it's £498 and I'd receive an invoice detailing breakdown after I've paid. I paid and and chasing twice, they finally sent the invoice over. They charged £45 for the plumbers tape! Considering the plumber left the empty container here so I could search it's cost - which ranged from 30p - 55p. Tried to contact them by phone and email after to let then know I'm unhappy with the 8100% markup on materials and I don't get a responce. STAY WELL CLEAR OF THIS COMPANY!
