These guys have quite simply been elevated to my Go to engineers in MK whenever I have a boiler/radiator issue. Professional, helpful, swift and reasonably priced.

Neat and tidy work.

Efficient service, polite and courteous engineer. Highly recommend.

Brilliant service form booking the visit to having our annual boiler check, friendly staff with great knowledge and advice will be booking them again next year

The worker have a good manner and skill set.

Fantastic company to deal with, and would not hesitate to recommend them.

Excellent friendly service from the team at Grand Union as always! Love their technology alerting the expected arrival time etc.

Grand Union redid our bathroom for us. Great experience from beginning to end, very professional and bathroom looks brilliant. Thanks again to Harley, Mitchell and the team!

Very helpful and quick response reasonable pricing.

Thank you Marco for replacing our kitchen tap. Prompt, professional, friendly and reasonably priced. Definitely recommend this company to all. Fenny Stratford

Professional, timely and courteous and kept me regularly updated on progress.

This was a return visit to replace some parts on the boiler. They were their usual high professional selves from making the appointment to fit in with me, notification of ETA of when Marco would arrive, which is always useful and, impressively, they stick to it. Job was done efficiently and everything left tidy. Very pleased.

I have always used Grand Union and will not use anyone else, they resolved a shower issue for me quickly, reliable and prompt as usual, thanks again.

From first contact with Mitch and then Lauren with regard to our plumbing issues it was clear that I was dealing with a very professional organisation who were interested to help solve our problems. The plumber Tomasz then did an excellent and fast job(s) fixing our two toilets. Highly recommended.

Careful planning and execution of work. Time taken to consult with creative solutions. Great service and responsible outcomes

From the initial phone call from GUP&H to book my appointment to repair the issue through to the site visit, I am over the moon with the service. I received a text to say the engineer was on his way. Very respectful of the property and gives feedback on the issue and next steps. Can’t ask for more. Great 😊

I love my new outside tap! Thank you. I look forward to future correspondence.

Very friendly customer service and great job by the workers A++++++ well recommended
