On a new combi boiler installation, as standard, you'll get the boiler, all required flue accessories, a system flush, new Boiler Plus compliant controls, a magnetic boiler filter and any extras, such as a gas pipe upgrades and/or condensate pipe upgrades.
On a new regular/system boiler installation, as above, you'll get the boiler, flue accessories, flush, a magnetic boiler filter, gas and condense upgrades and we'll reconnect to your existing boiler controls and cylinder.
We also offer upgrades, such as smart thermostats to remotely control your new boiler, improved flushing options and more.
Simply put, after your new boiler has been installed, you don't need to do anything.
Our team will register your new boiler's warranty directly with the manufacturer and we'll also register it with Gas Safe so they're aware of the new appliance. The only thing you'll need to do is get your new boiler serviced annually (this is important to keep it running well, but, most importantly, to maintain it's warranty).
On average installing a new boiler takes between 1 to 2 days to complete.

Takes 1 day
A boiler replacement, including a relocation:

But, the typical costs for installing a boiler are:
Combi boiler replacement:
£1,800 - £2,800
Regular boiler replacement:
£2,000 - £2,800
