Our boiler installations are comprehensive, so you get a seamless, worry-free experience from start to finish
We only install new boilers from market-leading brands like Worcester Bosch, Vaillant and Viessmann. Because of the volumes of boilers which we install, we get exclusive deals on warranties, meaning that they all come with up-to 10 years of protection.
As part of your fixed price, your new boiler will be fully installed to exacting Gas Safe standards, and fully audited afterwards. What’s more, we’re constantly monitored by Which?, who make sure our standards don’t slip.
All new combi boiler installations come as standard with our BoilerPlus compliant, energy saving controls. They’re totally wireless, and super easy to use. If you want a smart thermostat, you can upgrade to a Nest, Hive or Tado during checkout.
Any required alterations or additions to your home’s pipework are included in your fixed price. That includes upgrades to your gas pipework, and condense pipework. If your boiler installation requires it, the work will get done, and you won’t be charged a penny more.
To ensure your new boiler lasts a lifetime, our engineers will thouroughly clean your existing pipework and radiators with a hot chemical flush. This’ll protect your new boiler from damage, and also make it run more efficiently, saving you money on your bills.
A boiler without a flue, is like a sausage without its roll. That’s why all new boiler replacements from Heatable come fully installed with a new flue (horizontal or vertical), any required extensions, and any required safety attachments.
Not only will we flush your system during your boiler installation, we’ll help to protect it even futher too, with the installation of a magnetic filter. These little gizmos trap debris, dirt and all kinds of nasties from wreaking havoc on your new boilers internals.
Once your old boiler has been removed from your wall, it’ll be removed from site too. Then, it’ll be recycled. We don’t stop at the boiler either, any other waste such as old pipework, tanks or system gubbins will be taken away and disposed of for free.
When we fit boilers, we don’t forget. Following on from your installation, you’ll benefit from our exclusive 12 month workmanship warranty. So if there’s any sort of problem, it won’t be a problem.

This largely depends on the efficiency of your current boiler and how much energy you use. For example, you could save as much as £840 per year if you are upgrading from an old G-rated boiler to a modern A-rated boiler (along with a programmer, room thermostat and thermostatic radiator controls (TRV’s)).
