Boiler moved to loft - highly recommended

From the off, Nathan’s communication was brilliant. He was quick to respond and we got a date booked in quickly. Nathan gave us good, balanced advice on what we were doing and we actually ended up with a better solution than what we had been thinking previously. Work was completed on time and to a high standard, and they left the house clean and tidy. I will definitely be calling Nathan about any future work.

I used Gas Pro Plumbing for a boiler service and they were spot on from start to finish. Nathan was very quick with his communication and Josh was professional and polite when he carried out the service. He gave me advice on my heating system and was quick and tidy. I would recommend the company and plan to use them again for my next service.

I had a boiler replacement from the company. From the word go I have had very clear communication from Nathan responsive and interactive. The quote process was good- appraised the pipes etc and gave recommendation for boiler that would work in our situation; no hidden costs. The installation was fast , efficient and the installers, Sean and co were excellent ; fitted the boiler and drain pipe as I asked and actually resolved legacy issues with water exhaust that have accumulated. Put water exhaust into my sink drain for no extra charge and actually helped sort a leak there in process . The Veissman boiler itself is great. I have all certificates by the time they left electronically. Very satisfied wit the work done and the post service communication. They offered a call back to make sure system cleaned out and protected as standard.

I needed to replace my 15 year old boiler that had packed in. Nathan and his colleague came within 5 working days of my original call. They arrived on time, worked efficiently and tidily, using dust sheets to keep my house clean and taking rubbish with them ( I recycled the cardboard from the new boiler). The new boiler works great, it’s quieter and the central heating is noticeably warmer. A great job by Nathan, I would recommend this company.

Boiler Installation - Great Service

Nathan and Shaun did a fantastic job and I would thoroughly recommend them. The whole experience from initial discussions, getting the quote to having the boiler fitted was done in a quick and professional manner. The communication and advice from Nathan throughout the process was really helpful and he was happy to answer any of your questions or queries as well as provide recommendations. On the day of the installation the team turned up when they said they would and were done within 5 hours. They cleared the site of all rubbish and throughout the installation Nathan walked us through the system, the app and how it all worked, so we weren’t left confused. Great service.

My boiler broke on a Friday, Nathan was recommended by another gas engineer and soon got in touch to discuss options, budgets and availability. Nathan and Shaun arrived promptly on Monday morning and installed the new boiler quickly and efficiently, they were done by midday. They were great with good communication, tidy (including organising the collection of the old boiler) and ensured I knew how the new boiler operated. I would highly recommend. Thanks guys!

I had a new boiler installed and Nathan was incredibly helpful from start to finish. When my old boiler broke I didn't have any hot water so he arranged for someone to fix my old boiler temporarily until he could come round to fit my new boiler. He made sure I understood the smart thermostat and how to use the app. Both he and Shaun were courteous, communicative and tidy. I would definitely recommend them.

Nathan, Josh and Shaun all arrived on time and were quick to get on with the job. They completed in good time and with no damage to our ceiling. I would thoroughly recommend them to anyone else who might need a new boiler installed, as they worked together as the perfect team. Nathan has over 20 years experience and knew exactly what to do with what we were told was a difficult job.

Found Nathan and Sean on Which? and they lived up to their top rating, for installation of new Viessmann boiler. Arrived on time and immediately set to work. Quiet, polite and hard working. Finished by lunchtime and left it very very tidy. Clear explanation with all paperwork ready on completion. Arranged collection of old boiler within the hour. I highly recommend.

This was the second annual service of our central heating system which was fitted by GasPro. We had a prompt response to the request for service, and on the day Josh phoned to say he was on his way, with an estimated arrival time. The service itself was carried out speedily and efficiently. Happy to recommend this company.

Nathan came to quote for a new boiler to replace our old one which had broken down. He was able to fit a new boiler 2 days later and provided a very efficient service. We are very pleased with our new boiler which is working brilliantly. The process was smooth and everything was left clean and tidy.

Nathan and Shaun arrived on time at my new home and cracked on with the job. They installed a Viessman Vitodens 100-W boiler, swapped in all new rad thermostats and fixed a couple of stuck rads. 12 year guarantee is good! The GasPro has been servicing heating for me for over a decade at my last house. Totally trustworthy and professional.

The team installed my new gas boiler one year ago. The whole process was very fast and smooth. Very good value for money for a top of the range boiler. Today they returned to do the first service. All went well - punctual, polite and efficient. They are always very responsive and have even solved a problem when I was out of the house abroad and had guests staying in the property. Excellent company!

Nathan and Sean installed our replacement boiler in a remarkably short time, and with a minimum of fuss. They also installed a new radiator, explained how to operate the new boiler, liaised with Wales and West Utilities to bring our gas supply pressure up to standard, arranged to return in two weeks to flush the cleaning substance out of the system and refill with Fernox protector, and left the site cleaner than when they came. Exemplary professionals.
