How we can help you

If you’ve ever spent hours on the phone to a national plumbing firm or gas provider, you’ll know how frustrating it can be. Jumping through hoops to get to the correct department, facing long wait times for assistance, and not knowing who will eventually turn up: all this amounts to an unnecessarily stressful situation, especially in an emergency.

When your gas or heating is on the blink, you’d rather be in safe hands with an experienced and trustworthy professional who can deal with your problem quickly and reliably. We have more than 30 years of experience and pride ourselves in our ability to provide straightforward, reassuring and practical resolutions to all your heating needs.

I wish all trades people were like Paul Addy. Paul gave me straightforward, excellent advice on the choice of balanced flue gas fire for my large living room and carried out the installation work proficiently and neatly. Paul is a very conscientious worker who also pays attention to the detail and I would fully recommend his services. Lesley Wainwright

Prompt response to original query. Quick turn around from point of acceptance to work going ahead. Clean, tidy, well mannered and the service engineer went out of his way to discuss other issues within the home at the same time. Excellent service, I would recommend. Sally Foreshore

CMS Gas supervised by Paul Addy, recently installed a combi-boiler full central heating system and independent gas fire/fireplace plus a fully furnished shower room – transforming existing bathroom and utility cistern cupboard – to my complete satisfaction. Paul gave good advice, organised ordering/delivery of goods and materials as well as providing, and managing, all support services, i.e. plastering, wall and floor tiling, decorating, skips, etc. All work was carried out in a professional, confident, polite and punctual manner to a tight timescale. I found Paul and his team reliable and trustworthy and have no hesitation in recommending CMS Gas for any similar type of project. Annette Linfitt

Believe me, Paul is the best, completely trustworthy, excellent service and most pleasant personality. David Summer
