Cannot recommend Billy highly enough. We called him on Monday as discovered late on Sunday night that our heating wasn't working (isn't it always the way that it stops on the coldest days?). He arranged to come at 9am and was incredibly prompt - a text message from him at 8:55 to say he would be there in 5 minutes. He fixed our boiler, which turned out to be a relatively simple fix, and then proceeded to complete a service of the boiler, since we needed that done anyway.
Whilst he was servicing the boiler, I was chatting about the issues we were having with the shower upstairs and the water pressure - since we had the shower installed two years ago, we have not been able to run the tap or flush the downstairs toilet whilst the shower is on, as it causes the shower to lose all pressure. I asked if he might be able to quote for the work, and he indicated that we would need to know where the bathroom was isolated from. He went hunting around and found the pipes in the bathroom -- and discovered that the issue had been that the original plumber never fully turned the water to the bathroom back on! He solved a problem that has been plaguing us for almost 2 years in a matter of minutes, because he was interested in solving the problem and thorough in understanding the problem prior to providing a quote. As a result, we have saved a significant amount of money on a pump we didn't need. (We will now be taking the matter up with the original plumbing company...not impressed).
I am ecstatic with the service - it's not everyday someone saves you from spending upwards of £900, and gives you back your heating as well!

Thank you Billy for your hard work, I am so relieved to be able to shower stress free again!
