Our Accreditations: Why Choose Three Counties?

Here at Three Counties we’re committed to providing our customers with industry leading products, dedicated, friendly and professional customer services, all combined with total value for money. As part of our commitment to ongoing customer support and service we are members of the following industry bodies:

  • Three Counties - Fensa registered

    FENSA Registered Company

    FENSA stands for the Fenestration Self-Assessment Scheme. Following Government encouragement, FENSA has been set up by the Glass and Glazing Federation (GGF) and other industry bodies in response to Building Regulations for double glazing companies in England and Wales.

    When replacing windows and doors, homeowners must comply with energy and thermal performance standards and ensure they get a certificate from FENSA or Local Authority Building Control to verify that their home improvements comply. FENSA enables companies that install replacement windows and doors to self-certify compliance under these Building Regulations without the need for a separate assessment from Building Control. Companies in the FENSA scheme, like us at Three Counties Ltd will provide you with a certificate confirming that their windows comply with the new regulations.

    Choosing a FENSA registered supplier for your double glazing home improvements gives you peace of mind. As a FENSA registered member, here at Three Counties Ltd we have made a commitment to compliance with the new regulations and offer deposit protection insurance and insurance-backed guarantees.

Was looking for a new front door, to replace our tragically 80's monstrosity. The Three Counties website was great as i could see and design the door i wanted and then get a quote for it. The sales team was really quick to respond, and not at all pushy. A survey was easily arranged, to confirm sizes etc and the installer turned up precisely on time, was super friendly, efficient, neat and very tidy. Whole process took about 4 weeks, beginning to end, and I now have the door of my dreams! The only downside is my neighbors keep pestering me for details of who did the job. No hesitation in recommending Three Counties.

I'm very happy with my new conservatory - Mark and David did a brilliant job of the build and resolved any issues I had to make sure everything was finished to a really high standard.

This is the second time I have used Three Counties , a few years later and in a different house this time. It’s great to see the quality of the windows and workmanship have remained 5*. A stress free installation from start to finish, all windows installed have transformed how our 70s style house looks and now no worries of mould as a result of the old timber framed windows. The Installers who completed our job were amazing, and I mean amazing! Hard working, extremely skilful at their trade, polite and very tidy. Each day when they left they hovered up and left the place in the best condition they could. The whole process from the initial quote , measurements and dealing with the office team before and after the installation has been a true pleasure , if only all businesses were as efficient as this. Highly recommended for anyone considering new windows or any other products they provide and I won’t hesitate to use them again. Thank you Three counties!

I shopped around and three counties came in at the most reasonably priced, and I used the buy now pay later option. Really happy with my new door and window, which were both fitted in one afternoon. The customer service was very good throughout and everything went smoothly.
I had some windows fitted a few years ago and have recently had a problem with one of the locking mechanism failing. I called 3 Counties, who had a base call out charge, where a lovely lady took my details, refered to my file and we agreed a date when the fitter would come out and inspect the issue. Paul arrived bang on time and was very helpful. He checked the window, confirmsd the issue and promptly fixed it there and then with a replacement part he had on board his van. He was polite and knowledgable. Very efficient. Thank you 3 Counties.
