Having been in business for 50 years, I have dealt with some real cowboys in the telecoms industry. I have to say that Maincoms are without doubt by far the best telecoms company that I have had dealings with. Nothing is too much trouble and they have gone way way beyond their duty. If you need a really good competitive telecoms company,these are your people. Roger Coates ( owner) R M Services.

As a company we rely so heavily on our phone and Broadband to run efficiently and our previous provider failed to switch us over to digital nor get us into a new contract. When we saw the advert for Maincoms and spoke to James we were sceptical as main stream telecom companies had failed to deliver, it all felt too good to be true. However, from the first meeting with James through to installation with Daniel, all of the team at Maincoms have delivered exceptional service! It has been seamless and I would be more than happy to recommend them to any of our neighbouring companies! Our engineer Daniel was super knowledgable and helpful. The whole company have been amazing so far we are looking forward to using our new telecoms system.

From initial enquiry to installation and use, the team at Maincoms have provided us with an excellent level of support. We were provided with what we need, making use of existing equipment, which is refreshing where the industry's usual practice is to sell the latest, all-singing all-dancing, system. Pricing was clear and upfront with no hidden surprises. We would recommend the Maincoms team to anyone looking for a replacement to their existing tele coms supplier.

Maincoms have provided and hosted our phone system as well as our broadband for several years now. They were initially a recommendation and it's no wonder. They also provide similar services to our customers and are always on the other end of the phone when support is needed. A couple of them have been particularly helpful; Sarah has been great at helping with various queries including speed tests and diagnostics on lines. Dan has been valuable when it comes to knowledge and hands on support with routers, phones and networking. Thanks Maincoms!

We had great service from Maincoms from start to finish. They were patient went through everything with me, with their main aim being to get us the best deal possible. They were transparent about pricing and the nice thing is there is always someone to ready help you on their helpline.

Over the years we had totally messed up with our phones we had four separate suppliers and our billing was allover the place. To the rescue, Trevor and his Team, they have been totally fantastic, they have vastly improved all our services, they have sorted out all our previous suppliers, they are open and honest about costs, Dan installed our system at the office and at home, and has been absolutely brilliant, he has been on call at any time of the day or night, he fully respects our premises, every issue they have attended within days in some case hours and sorted out, their back up is the best I have ever had and I would certainly recommend them to anyone, you wont go wrong with Maincom Andy - Managing Director - Pressure Test

We've been really impressed with Maincoms. They've been completely transparent about pricing throughout the term of our contract, having bought us out of a less transparent contract with another supplier. The equipment is easy to use, the installation went very smoothly and they delivered everything they promised. Highly recommended.

I switched to Maincoms recently due to needing to upgrade my old phone system. Maincoms have been so helpful from the start. I met Trevor and he was very helpful and explained everything very well and also saved us money. The installation was plain sailing and the new phones are 100 times better than our old ones. I would definitely recommend switching to Maincoms if you're thinking of upgrading or changing.

Switched to Maincoms 3 months ago and was extremely worried and expected some sort of teething problems. What a surprise, could not believe how smooth and quick everything went. Trevor was brilliant in explaining everything, and the staff are more than helpful in any questions you have. Would highly recommend. When you need to make the change, Maincoms should definitely be considered. Also, everything is cheaper now, so added bonus!

Just moved away from an Hi-Hi System and Wow what a game changer our new system really is. The phones maybe not look as smart but they work unlike the Hi-Hi System so well worth the move.... Its a Bliss to have a system so friendly that you can work wherever you like even if you don't have your office phone with you the app is just as good. Would highly recommend these guys.

I would recommend switching. Good service from start to finish from Trevor. He made the whole process from consultation through to installation nice and easy and stress free. The system we have now is prefect for us. Andy who installed everything was brilliant. He was with us early and stayed until we was all up and running. Good price and service. The aftercare is really good any problems its just a phone call to the team and is sorted in no time.
