What Our Customers Say?

At CefniTech, we’re proud to be trusted by over 120 customers across the UK and beyond. Here’s what some of them have to say.

Excellent service - very quick response - fixed my problem quickly. Went beyond the original fault and left my Mac in much better shape. Gethyn very easy to deal with - polite and respectful.

C.Gibbs

Gethyn is really quick to respond and also very supportive and encouraging for you to have a go at sorting things out for yourself and then is available when you get stuck. Very reasonable rates, too.

L.Mundle

Not only is Gethyn's in depth knowledge clearly evident, he worked incredibly hard to sort out my emergency IT issues, working throughout the weekend, and probably not charging all the hours worked. It was difficult to find prompt emergency IT support over the weekend and such a relief to find him.

N.Cariglia

Working with Gethyn at CefniTech has been an excellent experience. He guided us through a challenging Microsoft-to-Google migration and solved issues that saved us hours of frustration. Always patient, thorough, and professional — I’d recommend CefniTech to anyone needing IT support. 5★ service!

J.McGilvray

Excellent service. Very professional and knowledgeable. For month my computer has played up, now it is better than when I first bought it brand new. It is so fast. I have no hesitation in recommending Gethyn's value for money IT services. It is comforting to know that I have this future support. Best in class that I have ever experienced through my working career. A big thank you.
