Marco kept us informed regarding arrival time and was spot on as usual. As with all of Mitch’s lads Marco is polite, friendly , professional with no bull along the way. Will always use Grand Union in future, if they can’t do a job Mitch always seems to know someone who can:)

Very prompt and efficient. Andy came right away, he explained everything and was very thorough.

As always, I would not use any other company! I am very happy with the service! Thank you All!!!

Marco is very efficient, respectful and quick action to schedule the repair. His work was flawlessly done to our kitchen sink which was leaking. Had put all the parts newly installed in a good quality recommendation. Well done to the company for having him.

Arrived on time as specified, very polite and professional engineer, clean and tidy up after service 2nd time used and will be using again for any plumbing needs thank you

Really friendly team, engineer explained everything that was done in a clear manner, the boiler service was carried out quickly and efficiently

I rarely complete reviews but this was a must. We had contacted GU for a service of our boiler. Marco literally came 3 hours later and completed one. Definitely the most efficient service I’ve used. Price was a lot cheaper than others too. Already recommended to a local friend who was looking for the same service. Thank you 👍🏽

Great experience with this project and great contact from start to finish .knowledgeable and friendly staff Turned up on time and very tidy with the work

I called GU when the controls of my elderly parents system packed up. Mitch came the next morning, found the problem and advised best solution to fix which he did the same morning. I couldn’t have asked for a more prompt, efficient and professional service.

Very friendly, supportive and reliable. I received a text message with a time slot and an ETA ahead of the driver arriving. Left the place as they found it. Have used for years and will use again. Highly recommended.
