What's included?

Boiler and pipework installation

Whether you’re getting a new improved system boiler or upgrading to a combi boiler, we appreciate that sometimes it’s necessary to have pipework alterations when a new boiler is installed. That’s why any pipework is included in the price of your installation.

Removal and disposal of your old boiler

At Padly we pride ourselves on ensuring our boiler installations are as easy and stress free as possible therefore, our engineers will ensure the removal and disposal of your old boiler is taken care of.

Removal of old tanks and pipework

If you’re looking to change from a system or heat-only boiler to a combination there will be no need for you to have a water tank in your attic freeing up space. Our installers remove old water tanks and boilers upon installation of your new system.

Chemical flush your system

After installing a brand-new boiler, we will complete a chemical flush, free of charge. Our engineers will complete a power flush designed to remove the sludgy build-up and grime that can accumulate in your central heating system over the years so you new boiler can work side by side with a clean central heating system.


Your new boiler installation will go hand in hand with a new thermostat. We will give you the choice of a standard replacement or upgrading to a smart thermostat to become compatible with smart home technology such as nest.


All our boilers come with a manufacturers warranty; however, the length of these warranties is dependent on the boiler you choose. For example, our Worcester Bosch Greenstar range comes with a warranty of up to 10 years.
