Our Elite Installer Network

99% of installers are not trained to get boilers running their A-rated efficiencies. We've done the work to find the UK's top installers so we can refer you on to them.


A boiler is only as good as the installer that fits it.

Boilers are not A-rated 'out of the box' and most are only C-E rated in the home

99% of installers are not trained to setup a gas boiler to run optimally. 

We have built a network of installers who can.

A boiler is only as good as the installer that fits it

The importance of a competent installer cannot be overstated. Just to be clear, when we talk about competence, we are not talking about being Gas Safe registered. We are referring to the ability of the installer to setup the boiler or heat pump to run as it was designed to. What do we mean by that? Modern condensing boilers are much more complicated than non-condensing boilers and need to be finely tuned to an individual heating system in order to run at higher efficiencies. This fine tuning is not understood by 99% of installers and so this knowledge is not there to be carried over the heat pumps,

A-rated is not achieved 'out of the box'

A boiler installation is far more complex than a washing machine replacement and consumers have to rely on industry standards and installer competency to get the whole heating system right. However, very few installers know that it is their job to configure the boiler, heating control and heating system in the home to achieve A-rated efficiency. The truth is that consumers have been massively let down by a industry that has simply not got its act together over condensing boilers. As a result our boilers are replaced long before their predicted lifespan of 22 years.

Skills gap

The skills gap

This shortfall in awareness is not necessarily installer ignorance. There is very little training in heating system design because nobody in the industry - or regulating the industry - has prioritised it. The move from non-condensing to condensing boilers led to a boom in gas boiler sales, but no corresponding investment was made to upskill the tens of thousands of installers needed to fit them correctly. The skills gap is so large now it would cost millions and probably take a decade to put right. Our biggest concern is that the shortfall in knowledge is being carried over to renewable technologies including air source heat pumps.

What we look for in an Elite Installer

There is a small group of gas installers who have, through their own hard work and self-learning, risen above the low industry standards to understand correct heating system design. It is these heating engineers that have made it onto our network. Each one has been technically assessed and can demonstrate that they apply their knowledge to their installation practices. Installers on our network must only use boilers/heat pumps from our shortlist of high-tech, high efficiency products and work to a high standard.

Our Elite Installers work to our higher installation standard

With the help of our Expert Panel, we are raising standards in the industry by making correct system design mandatory for our installations. We have devised a new higher standard - the Healthy Heating Standard - to ensure higher efficiencies and longer lifespans through 1) correct design methods and 2) short-listing the best boilers and heating controls based on impartial, technical assessment. Our Elite Installers are already working to this higher standard.

How we work with our network

Good installers are hard to find, we know that, so we have built a network of technically competent installers that we can refer our customers on to. They are all local independent businesses and do not sub contract to us. If you decide to work with someone on our network you will work directly with them in the same way you would work with any contractor. We do not manage their diaries and cannot guarantee their availability in your time frames. We can assure you of high standards.


Our Elite Installers are available via our 1-2-1 advisory services. We are the UK’s first independent advisory service that prioritises correct heating system design and efficiency over fast-track sales. We provide a specification for a correctly set up heating system, either a gas/oil boiler or renewable heat source, and where required we can make a referral to our installer network for you to progress directly with them.
