Full Rewire & Vaillant Boiler Installation
⭐⭐⭐⭐⭐
We used TNG Services Ltd for a full property rewire and the installation of a new Vaillant boiler. From start to finish the service was excellent.
The electrical work was completed to a very high standard, and the new boiler installation was carried out professionally with great attention to detail. Tomas and Gabriel kept us informed throughout the project and were always happy to answer questions.
Everything was completed on time, left clean and tidy, and the heating system is working perfectly. Reliable, knowledgeable and easy to deal with. We would not hesitate to recommend TNG Services Ltd for both electrical and heating works.

I contacted TNG Services Ltd because my Ideal unvented hot water cylinder had started leaking. Tomas attended promptly and carried out a thorough investigation. Unfortunately, it was found that the leak was caused by an internal cylinder fault and could not be repaired.
Tomas clearly explained the issue and handled everything professionally. He then arranged for the cylinder to be replaced under the manufacturer’s warranty with Ideal, taking the stress out of the whole process.
The communication was excellent throughout, and it was reassuring to have someone knowledgeable dealing directly with the warranty claim and replacement process.
I would highly recommend TNG Services Ltd for any plumbing, heating, hot water cylinder, boiler, or electrical work. Reliable, professional, and very helpful from start to finish.

Used TNG Services recently for some electrical works in the garden including making good afterwards. Really impressed with the overall service from start to finish.
The old system issues were sorted quickly and professionally, and the electrical work outside was completed neatly with attention to detail. Everything was left tidy afterwards and the garden area was made good properly once the installation was completed.
Tomas and his colleague were punctual, knowledgeable and explained everything clearly throughout the works. It’s difficult to find a company that can genuinely handle electrical works to a high standard, so I will definitely be using TNG Services Ltd again in the future.
Highly recommend.

We booked TNG Services Ltd to repair our Vaillant boiler after it kept showing an F75 fault and losing pressure. Tomas arrived on time, carried out full diagnostics and quickly identified the issue causing the fault.
The repair was completed professionally and at the same time the boiler was fully serviced, including cleaning, safety checks and combustion analysis. Everything was explained clearly and the boiler has been working perfectly since.

We booked TNG Services Ltd after seeing their YouTube video and realising our Quooker tap was overdue for a service.
At the same time, we asked them to replace our integrated dishwasher and investigate an awful smell coming from the kitchen waste whenever we used the washing machine.
Tomas and Gabriel arrived on time, quickly identified the issues and found that the dishwasher had been incorrectly wired by the previous kitchen fitter. He safely rectified the wiring connection and also corrected the kitchen waste pipe installation, which had previously been installed incorrectly and was causing the bad smell.
The Quooker service was completed properly, the new dishwasher was installed perfectly, and everything was fully tested afterwards.

I actually came across TNG Services Ltd after watching one of their YouTube videos about gas hob flames, and it immediately made me realise something wasn’t right with mine. The flame had that yellow/orange colour they mentioned, which I hadn’t thought much of before.
I decided to get it checked, and I’m glad I did. Tomas came out promptly, inspected the hob, and explained clearly what was causing the issue and why it could be unsafe if left. He sorted it on the spot and made sure everything was burning correctly again.
Really knowledgeable and honest service. It’s reassuring to find someone who not only fixes the problem but also educates you along the way. Highly recommend TNG Services Ltd if you’ve noticed anything unusual with your gas appliances.

TNG Services Ltd responded quickly when I had a loud noise coming from my plant room. They identified a faulty circulation pump straight away and carried out a professional replacement. The new pump was installed with new valves and repositioned higher for easier access and future maintenance.
Great workmanship, efficient service, and very knowledgeable — highly recommended!
