Our boiler leaked on Thursday night and water was going everywhere. We managed to turn the water off and looked on yellow pages to get a plumber to fix this the next day. I was advised when I called that the labour was £65 for every half an hour. The engineer turned up and said he needed to change a part and will be back in 30-45 minutes. 2 hours later he returned with the part, brought mud into my flat and then decided another part was needed as the water had damaged the controller board. Not knowing much about plumbing I trusted the engineer. I took the faulty board away and brought a board back, not sure if this was the same board or a new one. He fitted the board and checked the boiler was working. He then went down to his van to write the invoice which came to a whopping £1290, £708 in parts. I signed trusting the company had completed the work and at a reasonable and fair price. After I began to think that this was alot and asked for a second opinion from another plumber. He advised that the parts at maximum would come to £280. I also investigated the parts on the internet and again these parts are available for £250. I felt completely ripped off and called the company on the Monday to ask for an explanation. A guy came on the call and said that you can't complain about the cost of parts after the work and compared it to buying a curry at one restaurant and getting a different price at another. He advised that the company doesn't pass on trade discount but at 200% mark up I feel that this is a complete liberty. The other plumber I asked to take a look quoted £650 for all the work including parts. When I asked for the engineers name and CORGI number the guy got very defensive and said you can't complain about the price of parts to this association. THIS COMPANY IS TAKING ADVANTAGE OF PEOPLE AND WOULD ADVISE PEOPLE TO AVOID USING THEM.
