What your heatpump hot water quote should cover
The quote considers the cylinder and installation work for your home. Components can include plumbing, electrical work, a switchboard upgrade where needed, access to the installation location, a suitable base, removal of the old unit, gas disconnection and reinstatement of the affected area.
Your firm quote identifies the work that applies to your home and what is included; not every job needs every component.
What affects installation cost
The cylinder model, your home layout and access to the proposed location affect the scope. Electrical readiness also matters: the circuit or switchboard may need work before the new system can be installed.
Whether you disconnect gas now or keep a gas hob and disconnect later also changes the work being quoted.
An estimate for your home
We do not publish fixed prices because every home differs. Ask for an indicative estimate and send photos of your existing hot water unit and the space around it. A gas bill is helpful but optional.

Why does keeping a gas hob change the scope?
If you keep a gas hob, gas disconnection happens later rather than as part of the hot water job, which changes the work being quoted.
