What customers say
"Flash Plumbing Company did several different jobs around our flat. One of them was fitting a massive vertical radiator and soldering pipes, as the previously installed radiator was wider. He did a fabulous job, which was very aesthetically pleasing. He is very polite, patient, and has very fair prices. I would highly recommend Flash Company."
"Ash did a fantastic job of fitting our new combi boiler! It wasn’t an easy install and as due to it being an old house, the pipes weren’t quite where we expected them to be but he managed to make it all work really well, came an a Saturday to make sure it was all finished for us and we wouldn’t have to have any more time off work and he was very clean and tidy in the process. The new boiler works brilliantly! Thanks Ash - highly recommended! :)"
"Had my boiler replaced recently and the whole process was smooth from start to finish. Ash was on time, polite, and explained everything really clearly. The installation was done to an excellent standard, no mess left behind, and the new boiler is working brilliantly. I’ve already noticed how much better the heating and hot water are. Really happy with the service and would definitely recommend to anyone needing a boiler replacement."
"Ash has just completed a boiler exchange (old Glow Worm to a new Vaillant with controls upgraded to Nest.) The whole job was completed as scheduled in one day. He arrived on time, protected everywhere and has done a very neat install. Where options arose he explained these and came up with good suggestions which I was happy to follow. He explained how everything worked and then cleaned up and left with the old boiler (and all the surplus packaging from the new kit). The price was very competitive and there were no surprises on the day. All in all the experience could not have been better. Than"

"My boiler suddenly stopped working and we were left without any hot water. Ash was a life saver and came out in the evening. He investigated the problem, found the fault and fixed it there and then. This is the second time I have used Ash and I honestly wouldn't use anyone else now. Polite, efficient, tidy and prices reasonable. Highly recommended. Read more"
"Excellent work from start to finish. If we could give a higher score than 10 we would."
"I contacted Ash on Monday 14th November, my 92 year old Mother who suffers with dementia, had been without heating for over 2 weeks. A new boiler was required urgently. Ash supplied and fitted a new boiler on Wednesday 16th !!!! Excellent service, Ash is very kind and patient, he was brilliant with my Mum. I live in France and had to find a solution for my Mum long distance urgently. I would certainly recommend Ash to anyone in search of a genuinely fast, efficient, friendly and competitvely priced service . Read more"
