New Gas Boiler Installations

When you need a new boiler, you also need a trusted engineer who can recommend the right make and model for your property, and then install it correctly. Our engineers have a deep understanding of today’s heating options and can install any type of hot water or warm air gas boiler on the market.

So whether your gas boiler needs replacing, you need to save space by installing a new combi boiler, you want a more energy-efficient model, or you’re looking at how to integrate low-carbon heating options, we’re here to help. Our Gas Safe-registered installers carry out gas boiler installations across London and the Home Counties.

Benefit from an extended warranty

As independent boiler fitters, we have the freedom to install nearly every kind of domestic gas boiler available. Despite this, we tend to install more Vaillant and Worcester Bosch boiler models than any other brand. That’s because these manufacturers offer a wide range of reliable boilers, can provide extended warranties, and are known for their excellent customer service.

Aspect is part of the Worcester Accredited and Vaillant Advance installer programs. When we install a boiler replacement from one of these brands, you can get between 2 and 5 years added to the standard warranty period, depending on the model and any additional parts, such as magnetic filters. This means some of the boilers we install have a warranty of up to ten years; that’s almost the entire expected lifespan of some boiler models.

This makes us ideal for new gas boiler installations, especially when you need friendly advice and recommendations from a trustworthy boiler fitter serving London and the Home Counties.

Once the job’s complete, we’ll register your boiler with Gas Safe on your behalf, which is a legal requirement under building regulations. You’ll then receive a certificate of compliance to show that your energy-efficient boiler has been correctly installed and fully tested to work safely.

Professional servicing

Every boiler needs a yearly service, otherwise you run the risk of a breakdown and could lose your manufacturer’s warranty.

Ready for a hydrogen future

Prepare for the future of gas boiler installations with a model that’s able to run on a 20% hydrogen blend. Many of today’s boiler ranges can already do this, but if you’d like to be sure, our boiler fitters are always happy to recommend a model that’s confirmed as hydrogen-blend ready by the manufacturer.

With one of these cutting-edge models from one of our skilled boiler installers, you’ll be fully set for when hydrogen will be mixed into the gas supply as part of the UK government’s CO2 emissions policy. Even better, these boilers work just like any other that you’re used to and they cost the same amount, so there’s no reason at all to avoid buying a new boiler that’s hydrogen-blend ready.
