"We had issues with a leaking radiator late on a Sunday evening, and after speaking with Mill on the phone and sending him photos, he came to the house within the hour to fix the problem. He thoroughly checked all the radiators in the house too, to make sure there were no other problems. He was very professional, and easily the friendliest tradesman we’ve had to our house, and did it all at a very good price too, especially considering the time. He even helped with an issue with our toilet. We would definitely recommend GSG plumbing and heating, and if we need any work done in future, they will definitely be our first choice of who to go to. Thanks so much again!"

"Have used Mill a few times - he always comes promptly, is friendly and professional and does a great job. The last time we had a problem with our boiler he felt there were a few potential causes - he therefore suggested that we use the manufacturers one off fixed price repair as it would work out cheaper for us overall, even though it meant less money for him! Would happily recommend him to anyone."

"This chap came out and capped off my gas supply in my lounge. He was very professional and very reasonable in price. He also did a lovely neat job and came up with a solution when I didn't want to much mess or too big a job which suited us fantastically. Would recommend."

"I rang Mill this morning, he came within the hour, very knowledgeable and helpful, he fixed the leak under my sink and gave me good advice about my boiler. I definitely recommend him and will be using him in future. Also he is a lovely man."
