1. Get a guide price
Use the guide price tool or call us with your postcode, property type and current heating. You get a guide range for a home like yours, with the grant position where you live, before anyone visits.
2. Free home survey
For installation enquiries a surveyor visits to measure every heated room, note wall, window and floor types, check each radiator, look at the pipework and find space for the hot water cylinder. They also look at where the outdoor unit can sit: a level base, room for airflow and servicing, and a position that passes the noise check.
3. Heat loss design and written quote
From the survey we calculate how much heat each room loses on a cold day and design the system around it: heat pump size, flow temperature, radiator changes, cylinder size and controls. Your written quote lists everything included, the price and any grant deduction. Payment stages are set out in the quote.
4. Grant application
In England and Wales, the MCS-certified installer named in your quote applies for the Boiler Upgrade Scheme grant and Ofgem contacts you to confirm. In Scotland you apply to Home Energy Scotland and need a written funding offer before work starts; we provide the quote and details they ask for. Northern Ireland has no dedicated heat pump grant at present.
5. Installation
Most homes take 2–4 days on site; longer if several radiators or new pipework are involved. Installers protect floors, remove the old boiler or heaters, fit the outdoor unit, cylinder and any new radiators, then fill, flush and pressure-test the system. Your heating and hot water are off for part of this time, and we agree the plan with you beforehand.
6. Commissioning, handover and aftercare
The system is commissioned and set up with weather compensation, the installation is registered, and you receive the MCS certificate where applicable, manufacturer warranty details and a walk-through of the controls. Manufacturer warranties pass to you and our workmanship guarantee is set out in writing in your quote. An annual service keeps the system efficient and is often a warranty condition.
Questions
What happens at the home survey?
The home survey is a visit to measure your home room by room and calculate its heat loss, which sets the size of heat pump and radiators you need. We also look at your existing radiators and pipework, where the cylinder and outdoor unit can go, your electricity supply and the position of neighbouring homes for the noise check. Afterwards you receive a written quote with the system design and price. See heat loss surveys.
Is the home survey free?
Yes, the home survey and heat loss calculation are free when you are enquiring about an installation. If you only want a heat loss survey and report, for example to plan a renovation, a stand-alone survey is a guide price of £150–£400, including VAT. Repairs work differently: a fault-finding visit is charged at a rate agreed before we attend, and servicing is a paid visit.
How long does a heat pump installation take?
A typical home installation takes 2–4 days on site, longer if radiators or pipework are being changed. The work usually runs in stages: the outdoor unit and pipe runs, then the cylinder and indoor connections, then filling, commissioning and showing you the controls. Your heating and hot water are off for part of the work, and we agree the plan with you beforehand. Timings are typical rather than fixed. See how it works.
How much disruption does a heat pump installation cause?
A heat pump installation causes some disruption, mostly while pipework is run and the cylinder is fitted. Floorboards may be lifted in places, a hole is drilled through an outside wall for the pipes, and heating and hot water are off for part of the work. Installers use dust sheets and tidy up at the end of each day. If radiators or pipework are changing, we explain which rooms are affected and roughly when before work starts.
