Grand Union Plumbing & Heating Arvostelua 

Very impressed with the speedy response and diagnosis which prevented more extensive work being done as recommended by Anglia Water. Great communication and transparent pricing. Recommended and will be using again

Professional, from start to job done.
And price is transparent.

Highly recommended.
I will use their service again.

Quick response, punctual, efficient and analytical, picked up obscure issue very quickly, problem dealt with followed up some sound advice and help going forward. Great all round service

Faultless in every aspect.
5 stars for everything, would recommend to anyone

Quick and efficient. Very friendly as well.

Excellent service and good professional job.
Tomasz is a credit to your business

Excellent communications and the work was carried out very efficiently and in a friendly manner. Good use of technology for booking an appointment and for payment.

Grand Union replaced an aging boiler and 3 x radiators at my house. The service was excellent throughout. Both Andy and Mitch were really helpful, tidy in their work and conscientious to get the job completed despite an "interesting" technical issue identified late on a Friday evening. I would recommend without any reservations.

Very delighted with the fast response to the work I needed in by bathroom, and I’m happy with the isolation of the shower. He was very professional and tidied up after himself, I would recommend him to anyone who needs work done.

Called last minute and so grateful got the job booked in. Tomasz was great fast professional tidy very helpful and a pleasure thanks all really pleased

Once again fabulous service from Grand Union. Mitch is so professional and did a great job installing a new radiator for us. The communication is really outstanding and the morning text confirming the booking then another when they are on the way is really welcome.

Prompt arrival after very short notice…. Andy was friendly, courteous and offered useful advice. Very helpful as this is my first annual boiler service in my new build property.

Would strongly recommend!

Easy to book in job
Always answer the phone
Very competitive pricing

Tomasz was very respectful of our property, courteous & quickly replaced our leaky tap and checked there was no leaks before leaving.

We needed our boiler serviced fairly quickly as it was making lots of noise. I found Grand Union on Trustpilot for companies working in or near Newport Pagnell.
I filled in the request form & Mitch phoned me very quickly & the service was booked for 2 days away.
I had a message early in the morning & another one saying the engineer was due in 7 minutes.
Andy serviced the boiler checking everything throughly & explained what he was doing. A really lovely man & I would recommend this nice company fully.

Mitch was prompt, professional and friendly and quickly located the problem with the boiler. He talked me through the whole process, showing me exactly what was wrong and how it could be mended. I was also impressed by the fact that, on the follow-on invoice, there were pictures of the work carried out - very good for my records. I'm glad Grand Union was recommended to me and I'm very happy to further recommend with five stars.

First time we used this company for a couple of relatively small jobs. We have already asked them to quote for something else and we are delighted to have finally found a reliable general plumbing firm. Big thanks.

Serviced system found water in side boiler checked it all and worked out it had come through the flue in last nights windy rain. Very happy.

Brilliant service and excellent staff ,friendly and reliant would definitely recommend this company to anyone with plumbing issues

We had two engineers on different occasions Andy and Tomasz both were friendly and professional, got the job done
