Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

New aerial installation
I contacted Geoff on behalf of my elderly parents who were having issues with their reception. Geoff was punctual, polite and knowledgeable. Result? Happy old Mum & Dad, Coronation Street is restored!
Work completed:
Excellent work
GMI was recommended to me by a friend. The technician who came to test our aerial and replace old wiring was efficient and polite. We were very impressed with how quickly and tidily he worked. We would be happy to recommend GMI.
Work completed:
Wonderful service
Geoff was professional, efficient and knowledgeable. The problem was quickly diagnosed and appropriate parts fitted quickly. Highly recommended local service.
Work completed:
Excellent service
My mast head amplifier became water-logged so stopped working. Geoff said freeview signal has been increased, so rather than sell a new amplifier he bypassed it. He was not fazed by the high-up location of the aerial.
Work completed:
Brilliant service - highly recommend
Brilliant service! Responded to my enquiry quickly, booked an appointment for 48h later, turned up on time, listened to my concerns, suggested a solution, completed the work and took all of the old materials away. If only every business operated like this! Highly recommend.
Work completed:
Excellent Service
We needed to have an aerial installed for use throughout our home. We chose GMI as they are listed by Which as a Trusted Trader and we wanted to be confident that we were using a reliable company with skilled operatives. It was an excellent choice. The service was first class and we are very satisfied with the work undertaken.
Work completed:
First class work
I contacted GMI aerials to arrange an additional aerial socket. Michelle was friendly and courteous and arranged for Geoff to call to review. I was provided with all pricing options to cover the scenarios which might occur - from replacing all cables and the aerial to adding amplifiers to boost the signal. Geoff arrived, identified what needed to be done and did the work quickly and professionally - going above and beyond. In the end, I did not need a full replacement of the aerial and Geoff explained everything and checked all the work. Geoff and Michelle are professional, friendly, courteous and fair in their pricing. I thoroughly recommend them to anyone who needs help with TV aerial work

Freeview/DAB Aerial Installation
I had an aerial installed on my new chimney stack with a cable run to the tv/amplifier position in the living room. The work was carried out quickly and efficiently to the quoted price. I would recommend them to others.
Work completed:
Superb service
Contacted GMI via email following Storm Darragh, which finished off our 40-year-old aerial. Next morning GMI confirmed our preferred appointment time (12/12/24) - arrived on time on the day, job done to remove old aerial and install new aerial very quickly and efficiently (45 minutes). We are very satisfied customers and would highly recommend GMI.
Work completed:
Very good service.
Geoff arrived promptly and quickly diagnosed the fault (the aerial booster in the loft had failed). The booster was replaced and reception is now perfect. We are very pleased with the service we received and would definitely use GMI again.
Work completed:
Excellent service
Geoff, the engineer from GMi Aerials, did an excellent job replacing an old aerial and cabling that was no longer working properly with a new, modern aerial that works perfectly. Geoff is extremely professional and a pleasant person to deal with. We would recommend GMi Aerials without hesitation.
Work completed:
Excellent company
Turned up on time, knew what he was doing, polite, tidy all at a a sensible price. Highly recommended.
Work completed:
Aerial work
Enquiry dealt with quickly and efficiently, questions answered simply. We were offered an earlier slot as Geoff had finished a job quicker than he expected. Arrived on time. We discussed the job and he gave advice which was accepted. Well pleased with the result 😀. Would recommend GMI Aerials.
Work completed:
Excellent
Had a problem with receiving transmission on our televisions. Quickly and efficiently sorted by Geoff at a reasonable price.
Work completed:
excellent job, reliable, honest advice
Geoff was prompt, reliable & knowledgeable. His quote matched the clear pricing structure on his website. He gave me honest and expert advice, & did an excellent job at the unenviable & precarious task of replacing the heavy old broken aerial on our chimney stack, plus installing new aerial points. Trustworthy & friendly, as is Michelle in the office, thanks to both. I 100% recommend GMI Aerials
Work completed:
Freeview and Satellite Aerial service
We booked the services of GMI Aerials through the "Which? Trusted Trader" recomendation and very pleased with the result. Arrived on time and quickly assessed our problem - very pleasant guy who really new his trade. We would certainly use GMI Aerials again. Thank you!
Work completed:
Loss of digital aerial signal.
Geoff diagnosed the problem in a few minutes and was able to fit a new wall socket and power unit . Friendly and professional service in less than half an hour. This should be your go to expert for aerial services, look no further. Superb quality service, thank you.
Work completed:
Superb Job
We called GMI Aerials out to diagnose a strange interference that even the BBC couldn't help identify. Geoff was with us in two days and would have been quicker if I'd been in. He identified the problem as a very old signal amplifier causing problems with 4g and 5g signals, and also identified a faulty socket on another TV that we hadn't recognised as a problem because of the major interference. He renewed all the faulty equipment with no mess and was friendly, polite and professional throughout. I'd wondered if we needed a new aerial but he checked and assured us that we didn't, avoiding several £100s more cost that another installer might have charged. Superb service and great value.
Work completed:
Simply Excellent
A very fast response to the loss of our TV signal and an excellent result - friendly, efficient, competent, - what else is there to say - highly recommended
Work completed:
A good job by a professional
Our external roof aerial had survived for over 40 years, but was increasingly insecure and potentially dangerous. Our experience with GMI was wholly trouble free. The appointment was made earlier this week, and Jeff arrived, assessed and priced the replacement installation at an acceptable cost. The installation was concluded in around an hour, and he checked that the reception on our TVs was at its best. We would happily recommend.
