Avoid this company at all costs. I called them because my boiler was leaking even when switched off. Their engineer told me I needed a part costing £650 and that, realistically, I should replace... See more

Productivity Boilers citation was by a wide margin the most moderate than its rivals, we had our heater introduced today and I can genuinely say the pipework is astounding.

The work was done well but we were annoyed at it not being finished till 9pm. We were tired and hungry. It could have been finished earlier if they had arrived 2.5 - 3 hours earlier than 11am. Consequently the explanation of how the system works was rushed and it is still not working to our satisfaction.

At first I was reluctant to find a new company to replace my broken boiler as my local guy was on holiday. After needing a boiler ASAP due to no hot water or heating. Efficiency Boilers gave me a quote, after speaking to the manager a price was agreed. Installer fitted the boiler into the kitchen cupboard. He dismantled the cupboard and his workmanship was impeccable.

Efficiency Boilers gave me a quote on a Vaillant boiler. British Gas quoted me over £1200 more with a 5 year warranty. I received a very good price and a 10 year warranty. Fitted on the 23/12/19. Working perfectly and heating goes on for less time and heats the full house! Great stuff guys!

Recieved an email to write a review on efficiency Boilers. Although we decided to fix our existing boiler and not get a replacement. The surveyor who came to our house was professional, knowledgeable and not pushy. He helped answer any questions we had & left us with great insight. We will definitely be keeping this company close!

I had these guys come out to my property to give me a quote along with two other companies. I found this company to be more genuine. I felt they knew what they where talking about. They did a thorough survey and adviced me on which boiler was best suited for my property. I opted for the fast install time, the engineer arrived at 9am and my boiler was installed with very little disruption. The engineer set up the app on my phone to control the heating and registered my warranty. I feel my experience was not a daunting one and I was well looked after.
