Boiler Installation — FAQs
How long does a boiler installation take?
A like-for-like boiler swap usually takes one day. Conversions, relocations or full system upgrades typically take two to three days depending on the property.
Which boiler brands do you recommend?
We regularly install Worcester Bosch, Vaillant and Ideal because of their reliability and warranty support, but we will recommend the best fit for your home, hot water demand and budget.
Do new boilers come with a warranty?
Yes. Depending on the brand and model, manufacturer warranties range from 5 to 12 years, provided the boiler is serviced annually by a Gas Safe registered engineer.
Do you handle the paperwork?
Yes. We register the installation with Gas Safe, notify building control and register your manufacturer warranty, so you receive all certificates without lifting a finger.
