Fantastic service, can't fault it. Aidan goes above and beyond to make sure he gets to you asap. And Gerry provided a lot of help too. Their work and advice was very much appreciated. Won't use anyone else in the future.

Had a very positive experience with Aiden from McCulloch Plumbing & Gas having been let down by another company. He kept regular contact with regards making arrangements & we were very satisfied with the standard of work. Very helpful & professional. Would definitely use this company again & highly recommend them to others.

Frequently Asked Questions
How much does a new boiler cost?
Most new boiler installations sit between £1,800 and £4,000 fitted. The price depends on the type of boiler (combi, system, or regular), the brand and warranty length, and how straightforward the install is. A like-for-like combi swap is usually at the lower end of that range; relocating the boiler or changing system type pushes it higher. We provide a fixed quote upfront so there are no surprises on the day.
How soon can you install my new boiler?
For most jobs we can install within a few days of you accepting the quote, often sooner for a straight swap. If you're without heating or hot water, we'll prioritise getting you back up and running as quickly as possible, usually the same or next working day depending on stock availability.
What warranty do you provide?
Your new boiler comes with a manufacturer's warranty, typically between 7 and 12 years depending on the brand and model you choose. The exact length is confirmed in your quote. Our installation work is also covered, so if anything related to the fit needs attention, we'll come back and put it right.
Which boiler brands do you install?
We install all the leading UK brands including Worcester Bosch, Vaillant, and Glow-worm. The right brand for you depends on your property, hot water demand, and budget, and we'll talk you through the options before recommending one.
Do you remove my old boiler?
Yes, removal and safe disposal of your old boiler is included as standard. We handle the full swap including any pipework adjustments needed to fit the new unit, and leave the area clean once we're done.
