DGN GAS Reviews 

Contacted Ravinder about servicing my boiler and mega flow. Good advice around mega flow and arranged the service. Ravinder kept me updated on WhatsApp around estimated time of arrival. He was very courteous and carried out the work with no disruption. Very reasonable in terms of price and will definitely use again.

Ravinder and his team attended the gas leak issue raised , when smart meter installation engineer found possible leaks in boiler or hob and pipes.
Ravinder and his team checked and investigated over two visits and found the long standing gas leak at couple of points and fixed it and also carried full service to the boiler and found that previous owners had not serviced the boiler since installation many years ago.
All heating was checked and assisting with further improvements with adding smart controller and also plumbing of new water softener.
Ravinder and his team are very attentive and professional at their work and always happy to attend at short notice.
He has also attended to my other rental properties.

I had the pleasure of working with DGN as part of my house refurbishment.  They were subcontracted by my builder and I could not have been happier with their service.  The DGN team was attentive, professional, accommodating and knowledgeable.  DGN installed a Vaillant system boiler along with a water softener and advised on which thermostats and water softener I should install.  Throughout the install, the team explained what they were fitting and once completed, they gave me a comprehensive walkthrough of the system.  DGN also handled all the guarantees and certificates for installed components.  The team worked diligently and maintained a tidy working environment whilst also being respectful of the property.

I had a few teething issues with the thermostats and UFH, but DGN were helpful every step of the way, making priority site visits to ensure everything was working as expected.  This is a company that clearly prioritises their clients and will work hard to ensure they deliver to a high standard.

Since the install, I've had DGN service the full system and as always, the service is excellent, everything is explained clearly and I'm left feeling confident that my boiler is ready for the winter months ahead.

I'm really happy to have had my system installed by DGN and plan to only use them for maintenance and servicing.  An absolute gem of a company that offers a high quality service every step of the way.

Rav and his team at DGN Services installed my Combi Boiler two years ago replacing an archaic Back Boiler. They now come back annually to service it and carry out a Gas Safely check (legal requirement for landlords). I cannot fault this company at all. They are on time, courteous and very good value.

Engineers were very respectful and cleaned up afterwards. Made sure everything was working right before leaving.

Highly Recommend DGN GAS ⭐⭐⭐⭐⭐
​I was originally introduced to DGN GAS through a friend's recommendation, and they have now become my go-to gas engineers and heating contractors across all my rental properties in Hayes, Ruislip, and Slough.

​Over the years, they have handled everything for me, including full combi boiler installations, Megaflo unvented cylinder installations, annual boiler servicing, and fast maintenance/repairs. Their technical knowledge is exceptional, their work is incredibly neat, and they are always completely reliable.

​I have already recommended them to several others, and I will definitely be using them for an air conditioning installation next.

I’m absolutely delighted with the service provided by Ravindra, the gas boiler engineer. He was friendly, courteous, and highly professional, carrying out the boiler service efficiently and to an excellent standard. He explained everything clearly, answered my questions, and was respectful and tidy throughout the visit.

A fantastic service from start to finish—I would happily recommend Ravindra to anyone.

Really impressed with the service. The engineer was very punctual, professional and carried out a thorough check of everything at the property. Communication was excellent throughout, and he took the time to explain everything clearly.

Overall, I’m extremely happy with the service and wouldn’t hesitate to recommend him. He’s definitely my new go-to gas engineer!

We used DGN GAS to fix a low flow issue in our hot water taps. They completed the work very efficiently and resolved it quickly. Ravinder and his team were highly professional, explained the issue clearly, and communicated excellently at every step of the way—from the first call to completing the job.

I’m really happy with the service I received from this company. They repaired my boiler quickly and efficiently, and later helped me with a blocked toilet. Everyone was friendly, professional, and genuinely helpful throughout. I really appreciated the care and attention they gave me as a customer. I wouldn’t hesitate to recommend them to friends and family, and I’ll definitely contact them again if I need help in the future.

Ravinder was very professional and would highly recommend him and his team. His response to emails was quick, he came for a free site visit and shared recommendations & options and on the instillations the work was carried out to a high standard.

Honest, reliable with an eye for detail, if you want quality at a fair price he’s your man.

Goes well beyond the standard gas engineer. Honest, helpful, reasonable and very experienced. What a company

Ravinder and everyone in his team is so great. They installed our combi boiler and 300L baxi tank and did all the plumbing on your extension and new bathrooms and did an amazing job. We are very happy with the work and professionalism they show in everything they do. Highly recommended Ravi for all plumbing or heating related jobs.
