Great Honest Service - Guaranteed
ATAG boilers are precision-engineered in Holland and use the highest-quality stainless steel and brass components. This explains why they are built to last. And why an 18-year ATAG Boiler warranty is possible. At the heart of every ATAG boiler is ATAG’s revolutionary iCon heat exchanger, manufactured from high-grade stainless steel.

An 18-year warranty for a domestic gas boiler was unheard of until ATAG boilers came on the market. The average boiler has a life expectancy of seven years, with a two- to five-year warranty. Most warranties on better-quality domestic boilers max out at 10 years — usually with conditions.
So, ATAG Boilers’ 18-year warranty really is something special. It’s an 18-year, ‘no ifs, no buts’ warranty — only subject to being professionally serviced every year. On top of this, the price of an ATAG boiler compares very favourably with other quality boilers too. But none of them will give you 18 years of trouble-free heating.

With ATAG boilers, whether they’re powered by natural gas or LPG, you won’t need specific boiler insurance or an expensive service plan that ramps up as the boiler ages.
The ATAG Boilers 14-year warranty covers all aspects of the boiler, so should anything go wrong, it will be repaired free of charge.
The only proviso is that the boiler be professionally serviced every year (just like your car) and the water filter be replaced.
All ATAG boilers are ‘A’ rated for energy usage. Not surprisingly, they are regarded as the most energy-efficient in Europe. What’s more, based on our experience, we reckon ATAG boilers can also help cut your annual gas bill by up to £200.

Facts which explain why they are built to last. And why a 14-year warranty is possible.
At the heart of every ATAG boiler is ATAG’s revolutionary iCon heat exchanger, manufactured from high-grade stainless steel.
It has unrivalled performance and, uniquely, maintains 98% of its original efficiency levels throughout its lifetime.
It’s so good that the Energy Saving Trust has given ATAG Boilers its ‘Endorsed Product’ status.
In addition, ATAG boilers also have the lowest NOx emissions in Europe, making them kinder to the environment.

A new 24 kW ATAG iC Combination boiler — complete with an ATAG ONEZone smart controller, water treatment pack and an Adey Atom filter — has an 18-year warranty.
Installed in your home, it will cost from £3,250 (including VAT) — you’ll appreciate that every house and installation is different.
Add on our ‘Bronze’ maintenance cover for your annual boiler service (£84) and replacing the water filter (£50) — over 18 years, that comes to £1,876.
So, after 18 years, your new ATAG boiler is likely to have cost you under £5,000, taking current inflation into account.
That’s around £1,500 less than other quality boilers — which are likely to use more fuel and won’t have an 18-year warranty.
So ATAG Boilers provide peace of mind, with excellent build quality, low running costs and a unique 18-year warranty, which all add up to fantastic value for money — saving you hundreds of pounds over the life of the boiler.

We build strong, long-lasting relationships with our clients and are delighted to have received exceptional feedback. Here are some of the kind words we’ve received…
Our boiler was on its last legs, and we had just had our first baby and couldn’t afford to replace it. Marc and his team at GHS have managed to fix it with some new parts, which should give it another few years of life. All the parts and labour were covered under our maintenance plan with them, so nothing to pay! Very happy indeed!

Amazing service I contacted them as I have to work from home and cant bear the heat of the summer and cant have a noisy portable air conditioning system as I have to make business calls and videos.
Within 4 days, my system was fully operational, totally safe, as well as how they worked, which was important for us, and super clean and tidy, apart from the gleaming new unit on the wall and the cool airflow, you would never have known they had been there at all.
Superb value for money; they were 34% cheaper than I expected.
Steve Blofield
Recently used Sam from GHS for some plumbing work. Flushed out my radiators at work, which fixed the issue of the boiler cutting out. Then done a job at my home. Really happy with the service and super friendly.
Scott Clancy
Excellent service from GHS. I contacted them online one evening, and they came round the next afternoon, unlike so many others that can’t make it for a week or two!! Very pleased.
Susan White
