Greg DunninghamTrustindex verifies that the original source of the review is Google. Very competent and professional company. Few minor problems as with any installation of this complexity but all dealt with and resolved. We previously had oil fired central heating for eleven years but when it leaked all over the kitchen floor at Christmas there was only one solution and Miller's had it. Now after two years we can honestly say you can count on Miller Installation. Simon and Wendy RoundTrustindex verifies that the original source of the review is Google. Millers are absolutely excellent. We bought a new property which already had an air source heat pump that had been fitted by Millers, so we felt it best to continue to use their services since they had fitted the system originally. We have been delighted by their customer service and technical knowledge and would have no hesitation in recommending them to family/friends. The new technology surrounding these new heating systems is somewhat complex and Millers have really specialised in being at the top of their game in this regard; some of our neighbours have been tempted by what appear to be less expensive services but have ended up paying out significantly owing to lack of specialist knowledge which has led to poor advice. We pay into the service plan which has proved invaluable as, when we have had any issues, we have been prioritised and have not been left without heating or hot water, which is so important to us having an elderly mum living with us. Special thanks to Ellen who is at the other end of the telephone and who has a wealth of knowledge in her own right which means she is often able to troubleshoot problems without the need for an engineer visit. Thank you so much to all the team at Millers, a thoroughly well deserved 5 stars! Bob GreenTrustindex verifies that the original source of the review is Google. I had a problem with my LG heat pump. Out of the blue we awoke to find that it had developed a critical fault and shut down. My 91 year old father in law lives with us so it is important that he has a working heating system. I phoned Ellen at Miller Installations who had been recommended to me by a neighbour and she arranged for Mike to come out to us in the early afternoon. Mike diagnosed the fault as a poor connection on the PCB switch and quickly got the system back up and running for us. Ellen is getting me a price for the installation of a new switch but in the meantime and most importantly, we still have hot water and heating five days later. I can't recommend Miller Installations enough. They are a pleasure to deal with. Bill LangleyTrustindex verifies that the original source of the review is Google. I trusted this company to remove my gas boiler and install a 12kW. I was right to do so. They did a great job, when they said they were going to do it. Happy days for everyone. Highly recommended. Sam HowlettTrustindex verifies that the original source of the review is Google. Paul was so helpful, he showed me a couple of options for my radiator, consulted with me all the way through and even helped me with some queries I had about my ASHP which wasn't related to the job today. He was great. Will definitely be using you guys for my heat pump servicing later in the year. Thank you again. Shelley BillinghamTrustindex verifies that the original source of the review is Google. Amazing,I’ve used this company on many occasions for my small Bussiness and they never fail to provide an excellent, reasonable and very professional service every time! The staff are great and always go above and beyond x would recommend to anyone ChaoGuy2006Trustindex verifies that the original source of the review is Google. They went above and beyond. Had an issue with my air-source heat pump after a previous careless owner, went kaput over winter, with an elderly person in the property. Miller were the original installers, and a savior. We were kept appraised every step of the way as the part was ordered, and they answered our queries even after 5pm. After it was fixed, we then got a proper lesson in how the system worked, and how to run it most optimally for our needs. Suffice to say, Miller Installations will be handling our servicing from now on. Massive thanks to Mike, Ellen, and Shaun.
