Extremely happy with the job. I had my bath replaced, new tiling done and taps/shower fitted. George was very communicative, helpful and completed the job quickly and to a really high standard. The tiler was fantastic too - would absolutely recommend both and will be using them again for further work next year. Thank you!

Excellent service, the problem was tricky as the boiler had suddenly failed with a blank control panel (fuse ok). Initial testing failed to find a fault but after some deep system checks the cause was discovered and he left me with a fully working system. He went the extra mile, definitely use again.

We are delighted with Tim’s excellent and professional service in fitting a replacement radiator and clearing a problem drain for my elderly mum. He responded straight away with his quote and I found him very reassuring when he explained on the phone how he would carry out the job and how he was able to complete the job within a week, which was perfect timing for us. He was friendly, efficient and completed the job to a high standard. We are very happy and would thoroughly recommend without hesitation.
