Compare quotes for air-to-air heat pump installation in Surrey
Heating a loft conversion or extension without running new pipework is the usual reason to ask about air-to-air. Note which walls the outdoor unit could sit against.
Send one enquiry for Surrey, and up to four independent heat pump businesses may respond, depending on the work involved and who has capacity. Matching costs nothing, and every quote can be declined.
Work to include in your enquiry
An air-to-air heat pump moves heat between the outside air and the room air directly, using refrigerant pipes between an outdoor unit and one or more indoor units. There are no radiators or water pipes in the system, and it does not heat a hot water cylinder, so the quote should cover heating the rooms only.
Things to mention when you enquire
- A room that is hard to reach with the main heating
- Plug-in heaters running through the winter
- A wish to cool bedrooms in summer
- No room for a plant cupboard or tank
- Interest in a multi-room system from one outdoor unit
On the day
The route for the refrigerant pipes is agreed first. A typical job includes:
- Fitting the indoor unit brackets and the outdoor unit feet or wall bracket.
- Drilling a small core hole through the wall for the refrigerant and condensate lines.
- Routing insulated refrigerant pipes, the condensate drain and the power cable between the units.
- Pressure-testing the pipework with nitrogen, then evacuating it before the refrigerant is released.
- Setting up the system, checking airflow, temperatures and the remote or app controls with you.
Single split or multi-split
A single split pairs one outdoor unit with one indoor unit. A multi-split connects several indoor units to one outdoor unit, which saves wall space but means each room shares the outdoor unit’s capacity. Ask the installer to explain what happens when every room calls for heat at once.
Preparing for the visit
Clear the wall where the indoor unit will hang and the ground below where the outdoor unit will sit. Ask where the condensate will drain, who makes good the core hole and trunking, and whether the outdoor unit needs a base or wall bracket.
Pipe routes and condensate
Have the installer show you the condensate route before drilling. A gravity drain and a pumped drain have different maintenance needs. Check who seals the wall penetrations and whether visible trunking is included.
Prices for air-to-air heat pump installation in Surrey
A sensible planning figure is £1,500–£5,000. A quote may fall below or above this range. A single split heating one room sits at the lower end. A two or three room multi-split with longer pipe runs is in the middle. Ducted systems, multiple outdoor units or long routes through finished walls take the price to the top of the range or beyond.
Ask for equipment, labour and any survey fee to be listed separately, with VAT stated. Allow 1–3 days as a guide for the work itself; equipment lead times and awkward access can add to it.
Information that speeds up a quote
Say which rooms you want heated or cooled and roughly how large each is. Describe the walls the pipes would pass through and where an outdoor unit could stand without blocking a path or a window.
Go through every quote item by item. Ask which brand and model is quoted for each room, the rated heating output of each indoor unit, the pipe length allowed for in the price and whether the electrical supply to the outdoor unit is included.
Regulations and approvals
Many air-to-air installations are treated like air conditioning units, but outdoor unit position, noise and the building type can matter. Listed buildings, conservation areas and flats with leases are the usual sticking points, so ask before ordering. Installers working with fluorinated refrigerants need the relevant F-gas qualifications and company certification where required. Grant eligibility depends on the property, system and scheme rules. Check the current Boiler Upgrade Scheme guidance for England and Wales, including eligible air-to-air systems, and confirm installer certification and application arrangements before ordering. Scotland and Northern Ireland have different support arrangements.
If you are not sure whether the council needs to know, ask Surrey County Council. If the job grows beyond what was quoted, confirm which approvals apply before the extra work starts.
Booking air-to-air heat pump installation near you
Businesses covering Surrey need the postcode and the nearest town or village. Flag shared access, narrow lanes or limited parking. Send photos of the walls you would like the indoor units on and the outside wall behind them. A nearby installation may have a different heat demand, so describe your own system.
Request quotes for this work
Use the free enquiry form to describe the job. Say whether you want cooling as well as heating, and name any room where noise matters more than speed of warming. Businesses that join are asked for insurance details and references. Before booking, read their current paperwork. We only pass the enquiry on: advice, pricing and the work itself come from the business you pick.
Questions homeowners in Surrey ask
How can I compare quotes for air-to-air heat pump installation in Surrey?
Fill in one enquiry form with your postcode, the rooms to be heated and the walls the pipes would cross. It can reach up to four independent heat pump businesses working in Surrey. Replies depend on the job and availability. You decide whether to book anyone.
Roughly how much is air-to-air heat pump installation in Surrey?
We use £1,500–£5,000 as a UK guide. Businesses in Surrey price their own work, and the number of indoor units, pipe length and wall construction affect the total. A written quote should list equipment, labour, VAT and any survey or call-out charge.
Does an air-to-air heat pump heat hot water?
The room-heating split systems described here heat and cool air, so you normally need a separate hot water arrangement. If a supplier proposes an integrated hot water option, ask exactly what equipment the quote includes.
Can one outdoor unit serve several rooms?
Yes, with a multi-split system. Each room has its own indoor unit, but they share one outdoor unit, so ask how the capacity is shared when several rooms call for heat.
Where should the outdoor unit go?
On a firm base or bracket with clear airflow, away from bedroom windows and shared boundaries where noise could cause trouble. The installer should explain the position they propose.
How long should I allow for air-to-air heat pump installation?
Allow 1–3 days as a guide. Ask for the quote to name every indoor unit, its output and where the pipes run. Equipment deliveries, pipework changes and electrical work can add time. Agree how long heating or hot water will be unavailable.
