Declan has been very reliable very quick and very reasonable with pricing.wouldnt recommend anyone else

Boiler upgrade are my company of choice. I use them for servicing my boiler. However I called them out as it had suddenly stopped working. Declan came out on a Saturday and stayed until he fixed the issue. This issue was difficult to find but he did it. I would always recommend boiler upgrade.

Just moved into another home. The property had stood empty for about 18 months, but a year or so ago a new heating system installed. We saw that Declan had installed it as his sticker was in the boiler. Looking at the workmanship of the install, I was impressed. Noticed however that the pressure gauge was low and that the radiators seemed to have so air in them. Contacted Declan who was happy to come over, check and re pressurise the system and show me how it’s done so if needed in future not a problem.
Really pleased with his polite manner, helpfulness and general approach to his work. In our professional capacity we find it difficult to find good, conscientious plumbing and heating engineers, so will definitely be recommending him to others and have already booked him for further works we require.
Thank you.

Emergency callout for Boiler. Declan arrived within the hour and arranged repair under warranty. Excellent service as usual.

This was a last minute request and Declan resolved the issue. He is always polite, friendly, efficient and very tidy.

Been using Declan for a couple of years now for boiler services and gas safety certs etc and I’d highly recommend him. Super helpful, quick to attend and very professional.

What a life saver Declan was when my boiler broke 2 weeks ago, he even gave me advice and a quote whilst he was still away on holiday. On his first day back he came round as promised and fitted me a new boiler, nothing was to much trouble and his workmanship was excellent.
I strongly recommend Boiler upgrade company to anyone who need a good, honest and reliable plumber, five stars just isn't enough in my opinion.
Thank you Declan for giving me heating again :-)

Fully recommend Declan for servicing the boiler. Responsive with communication for arranging the appointment and very efficient on the job and gave great advice. Thank you

Declan sorted out the bathrooms for my next door neighbours who passed his details to me. He didn't replace a boiler but put my new taps on my bathroom sink. I will be contacting him for further small jobs : new radiator thermostat, new shower plumbing etc. It is great to find a decent plumber.

Declan has replaced all the radiators and boiler in 2 houses for me now, fantastic work both times & very responsive to requests. Would recommend without hesitation to anyone.

I was so so impressed with this company. The plumber came out exactly when he said he was going to and actually text beforehand to say he was on his way. The work carried out was so clean and professional. The plumber was very polite and helpful. I would definitely recommend him to all my friends and anyone on social media asking for a plumber. Highly recommend!

I have used Declan for over four years and am really happy with his work. Recently he managed to fix my mother's boiler which broke down during the recent cold snap. All sorted within 48 hours of begging for his help at 7pm. Thank you.

I would like to say boiler upgrade are outstanding, the quality of workmanship is so high and customer service is superb, they come around and service my boiler every year,

Very happy with work Declan carried out. He is professional, punctual and straight forward. I would highly recommend.

Excellent Service as usual from Declan - he is very helpful efficient and well versed in his trade - highly recommendable
