What stood out most was the plumber called Ryan, his attention to detail and genuine commitment to solving the problem correctly, rather than offering a quick fix. It’s rare to find such honesty and... See more

Excellent Boiler Installation Service from Ryan

Huge thanks to Ryan, who fitted our new boiler! From start to finish, the service was professional, efficient, and stress-free. Everything was explained clearly, the work was done to a very high standard, and he left the place spotless afterwards. The new boiler is working perfectly, and you can really tell Ryan takes pride in his work. Wouldn’t hesitate to recommend to anyone needing a reliable and skilled plumber!

Radiator & Boiler repairs

This year, Ryan has been really helpful in fixing a long standing pipe issue and the radiator is now working. He also came out today to repair a boiler issue : completely separate to the other work. He was in the area and came by to sort this for us. Five stars all round! ⭐ ⭐ ⭐ ⭐ ⭐

Washing machine cold water supply.

I needed a job done quickly for a washing machine installation. I called Ryan and he came out that day on his way home. The job was done quickly and efficiently. Excellent service from Ryan.

Urgent Call Out

During the years since my boiler was installed I have had it serviced by various engineers. Ryan is without doubt the best and has done an excellent job of servicing my boiler for the last 2 years. His attention to detail and knowledge of Vaillant is amazing and he always explains clearly about anything requiring attention.
I contacted him urgently on a Sunday morning recently when the CH failed to activate and a fault number was indicated on the boiler. He came out later that morning armed with a new circuit board and the CH was up and running in no time for which I am very grateful.

Great, efficient service.…

Fast and efficient service at a very busy time of year. The father and son team gave a seamless service and Mr Mills senior even supplied me with sweeties. I couldn't have been more impressed. Truly a five-star experience. The team came recommended to me by a friend and I would not hesitate to recommend them to anyone with heating or plumbing needs.

Excellent service

Ryan & Gary have done work for my Dad for a number of years and are always really helpful and professional.

Recently serviced the boiler and also went above and beyond to sort out an issue with an outdoor pipe.

Would highly recommend.

Knowledgeable and efficient

GD Mills fitted my Vaillant boiler some years ago and have done the annual service since then. I would highly recommend this company. Ryan is reliable, professional, knowledgeable and personable.

Saved my kitchen

Ryan solved the problem of how to fit a boiler without destroying my kitchen. He keeps his appointments and does a great job.

Reliable & All Round Good Guys.

Been using Ryan & Gary Mills for some years now in our own home & family members too. Always found them reliable, on time & honest with their assessments. Just had annual boiler & gas fire service done by Ryan, thankfully both have behaved themselves. Will always use them so can easily recommend them to anyone in Edinburgh & Lothians areas.

Ryan came out to plumb our washing…

Ryan came out to plumb our washing machine into a cupboard. He was super responsive from initial contact through to completing the job, carried out the job in a really timely fashion for a reasonable price, was very pleasant to deal with, and left everything as he found it. We'll definitely be going back from any other jobs we have and we wouldn't hesitate to recommend!
