Very impressed by Nigel at Apex, polite, professional, arrived exactly when he said he would, left no mess behind, even had a card reader for payment convenience. 100% recommended.

Nigel has just fixed the low water pressure problem with our showers. The shower would just stop if any other tap is open in the house and the problem was getting bad to worse. Whilst three other general plumbers came and had a look at it, he was the only one who was able to identify the potential cause and suggested to replace the old valve controlling the inlet/outlet to Unvented cylinder. Guess what, much to our delight it fixed the problem and in fact the very next morning, I sent an email to Nigel saying that was the best shower I had in 3 years. Nigel came across as an expert in his field

As I have only just moved in to the area I did not know where to turn to find a contractor to replace a faulty thermostat. I saw that that Apex had carried out a service on our Megaflow for the previous owners of our house and contacted them
What a lucky find! They responded propmptly to my email enquiry and carried out the work exactly as promised and in accordance with their estimate. I will use them in the future and can highly recommend them

I called Nigel from Apex after my Megaflow boiler broke down. He answered and advised me to email my problem. After explaining the problem with photos he advised on costs and potential problems. He turned up on time fixed the boiler and was extremely professional and helpful. He also gave a discount on the bill. Highly recommended.

I have been struggling for 5 years with hot water in our house, have spent a fortune too. I came across Megaflo unvented site which was enlightening and informative. Its clear Nigel knows what hes talking about, he advised me what to do in the interim which has worked straight away, I really cant thank you enough. Sometimes you feel like your going crazy because other tradesmen say its fine and act like they know just to get the money. Appreciate the honesty Nigel, thanks again.
