The practical details, before you book.
Our combi boiler installations start from £1,945, including the boiler, fitting and VAT. Answer a few questions about your home to see suitable boilers and your fixed installation price before booking. Your quote covers the installation agreed for your home, so you can see what you are paying for.
Compare the boiler, warranty and included equipment alongside the price. You can pay in full or explore the payment plans available with your chosen boiler.
Your fixed quote includes the boiler, fitting and VAT, along with the equipment specified for your installation. This includes a magnetic filter, a chemical system flush and safety tests. We remove your old boiler where safe and show you how to use the new controls.
Combi replacements and conversions include a wireless thermostat. The full inclusions explain the allowances for flue and gas runs, plus exclusions such as scaffolding and asbestos removal, so you can review them before booking.
Next-day boiler installation may be available on weekdays, depending on your address and boiler availability. Complete your booking, payment and installation photos before 3pm.
Your quote shows the available fitting dates for your home. Choose a later date if that suits you better. Next-day availability is for boilers; our other services have their own installation schedules.
A straightforward, like-for-like combi replacement usually takes one day. A conversion or installation involving additional work can take longer. We confirm the expected timing for your installation.
Your heating and hot water will be off while the work takes place. Your engineer tests the new boiler and explains the controls before handover. Let us know about any household needs when arranging your installation.
Yes. Finance is available on eligible boiler packages. Your quote shows the available plans, including the deposit, term, APR, monthly repayments and total payable, so you can compare them before applying.
Boiler finance is provided by V12 Retail Finance and is subject to status, affordability and lender approval. LeadsUK Ltd trading as iHeat is a credit broker, not a lender. You can also pay in full by credit or debit card.
We ask for photos of your existing setup so we can review the installation before your engineer arrives. Keep the boiler and work area accessible, and tell us about any access restrictions or household needs.
Your Gas Safe registered engineer fits, commissions and tests the boiler, then shows you how to use it. Our in-house engineers review the installation evidence before final approval. Afterwards, our team can help with questions or arranging an installer revisit or manufacturer warranty call when needed. Manufacturer cover depends on your package and its registration and servicing terms.
