Our Services

We offer a range of energy solutions, backed by our industry expertise and versatile finance options, to make our customer’s energy saving goals a reality.

We’re great believers in the ‘whole house approach’, which is about taking a complete look at our customers’ homes and households to understand how energy is used and, just as important, where it is being wasted.

In addition to our traditional gas & heating services, we are the head of a country-wide network of installers that offers almost every kind of energy improvement available in the market today.  Insulation, renewables, ventilation, water saving…you name it.

We are always happy to talk about our favourite subject – saving energy.  So give us a ring, send an email or just drop in at our Wigan offices and let us hear more about your goals for saving more energy today.


Avoid the scammers, cold callers, con men and unqualified installers!  If in doubt, call us and we will check them out.

Heating Systems

Heating systems account for around 60% of a home’s total energy use, making them the first port of call when it comes to tackling high energy bills.
