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

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.

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.

Examination & Replacement Aerial

I contacted this company during the week of 4th April 2022. Arrangements were made for an engineer to attend the following week (13th April) Dave looked at the situation and immediately identified that one of the 2 aerials I had was not required and that the other one was disintegrating. He gave me a quote there and then to remove existing aerials and their cables, remove all unnecessary cables and fit a new aerial. He found a major fault with the main aerial which had been causing me problems which was good for me to know. The work was completed and he removed the original aerials and cables etc from my property. He made sure the signal from the new aerial was good. In fact it was excellent. Dave was an absolute gentleman. I would strongly recommend this company. Polite, Courteous, Respectful of Property and Professional.

Some Freeview channels were showing pixelation in strong winds. My phone call was answered in a couple of rings, problem discussed, and a slot booked for engineer to come and look. The office phoned back shortly after to say engineer was free now and was it convenient. Was able to show the problem although the test gear showed a strong signal. Decided to have a new aerial to replace the 40 year old one and the original slot was used for that. On the day Dave phoned to say he was on his way and arrived early, new aerial fitted outside, cable run length of loft, and old aerial taken away in under an hour. Great service.

I had 2 dishes and a multitude of cables on the walls and in the gutter. This needed rationalisation at a reasonable price. Plus when he was here I decided on a new dish in a new place.

I left a message just before ‪9am‬ about my octogenarian mum’s aerial breakdown and Michelle called me back within 40 minutes. We booked in a slot for later in the week but I was informed they would try and get someone out the same day. Within the hour I had received a call advising an engineer, Geoff, would be attending within the next half hour. When Geoff attended It was identified that a new aerial was needed and this was completed straight away - Geoff also removed a redundant satellite dish for us. Geoff was polite and courteous and kept my mum informed at all times of what he was doing and why. As I live out of the County it was reassuring to know she felt comfortable and happy with the service provided. Fantastic service from start to finish.

We've used Geoff and Michelle for about 5 years now on 3 different properties, setting up two completely new systems and resurrecting the dilapidated existing one on the main house. They really know what they are doing and are quick and efficient. This time our house Sky service stopped, no signal to any of the boxes. I followed the instructions on Sky's website to try and fix it and eventually Sky said they could send an engineer in 10 days time at a cost. 10 days! Rang up Michelle on Monday morning, and Geoff fitted me in! Bliddy marvellous. He had the parts in his van so all sorted within half an hour. Can't fault them, they're excellent and I can thoroughly recommend them.

This is the 3rd time we have used GMI Aerials, and yet again they have surpassed all expectations. They are a friendly family company that specialise in perfection. They can supply all parts and accessories but they never ever try and up-sell or convince you to have things that you don't need. Their workmanship is brilliant, and they will make sure that you have the best signal possible. Their prices are the most competitive around. and the best thing of all...They are honest! Thank you GMI

GMI Aerial were so very helpful to us when we had the upsetting experience of another company significantly overcharging us for a repair that wasn't required and didn't fix our aerial problem. GMI's support, together with trading standards, helped us put that right and then GMI came out and did the correct repair, at a reasonable price and in a timely way. I can't thank them enough for their professional and helpful manner and actions.

Our ancient aerial fell off in high winds, with various dangling wires. The GMI engineer arrived within a few days, at a scheduled appointment. He examined the problem and proposed a good solution and with a sensible quote, which we accepted. He fixed the new aerial and sorted out the wiring very efficiently within an hour. The result is an excellent signal (better than ever) and a tidy set-up. Strongly recommended.

Engineer arrived at the time agreed. He identified the problem within a few minutes and suggested a solution to stop the problem reoccurring by fitting a power unit in the loft instead of replacing the faulty one on the aerial mast. I was informed of the cost prior to him commencing the repair and everything was completed efficiently and effectively. The engineer was polite and courteous, explaining what he was doing, and why. First rate engineer and the person I contacted to arrange the appointment was extremely helpful. I can highly recommend this company, and it's a pity I can only award them 5 stars as they deserve higher praise than that.

I had a speedy call-back from Maggie in their office, after requesting a quote online. They were able to arrange a prompt visit, and the engineer called ahead as promised to give me an ETA. Geoff was very friendly, tidy, and did a great job; where other quotes had said they couldn't use the existing cables, he was able to sort it out, saving me having any new external cables run to disfigure the outside of the house. He was very quick - doing everything within an hour as promised, and the finish looks great. The price was very reasonable too. On a follow-up visit, the response was equally helpful, with the repair carried out quickly, they were up-front with costs, and a pleasure to have round. Would definitely recommend!

If all companies were like this, wouldn’t life be easy. This company sets the standard and I have no reservations whatsoever in highly recommending these honest aerial fitters to everyone.
