Get prices to fit an air-to-air heat pump in Portsmouth
A single split unit can warm one living room, but a whole-house setup needs an air-distribution design for all the rooms you want heated. Say which rooms need heating and cooling.
Tell us what needs doing at your property in Portsmouth, and up to four independent heat pump businesses may respond, depending on who covers your postcode. Matching costs nothing, and every quote can be declined.
What the installer will look at
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.
What you might be planning
- An extension or conversion with no radiators
- Electric heaters or old storage heaters in use
- Overheating in a south-facing room
- A flat or house with no space for a cylinder
- Wanting one unit for several rooms
What the installation team does
The installer should confirm the unit positions before drilling. A typical job includes:
- Securing the indoor unit brackets and the outdoor unit feet or wall bracket.
- Cutting a small core hole through the wall for the refrigerant and condensate lines.
- Running insulated refrigerant pipes, the condensate drain and the power cable between the units.
- Leak-testing the pipework with nitrogen, then evacuating it before the refrigerant is released.
- Commissioning 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.
Access and finishing up
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
Ask where condensate will discharge when the system cools the rooms. A gravity drain and a pumped drain have different maintenance needs. Check who seals the wall penetrations and whether visible trunking is included.
Paying for air-to-air heat pump installation in Portsmouth
Across the UK this work typically costs £1,500–£5,000. Treat it as a national guide rather than a local rate. 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.
Have each business explain its equipment and labour costs, any survey fee and the VAT position. Allow 1–3 days as a guide for the work itself; equipment lead times and awkward access can add to it.
What to tell the business
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.
When replies arrive, check what each one includes. 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.
Qualifications and consents
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.
Council questions for this area can go to Hampshire County Council. Ask your installer which consents they will deal with and which are left to you.

Questions about air-to-air heat pump installation
How can I compare quotes for air-to-air heat pump installation in Portsmouth?
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 Portsmouth. Replies depend on the job and availability. You decide whether to book anyone.
Roughly how much is air-to-air heat pump installation in Portsmouth?
We use £1,500–£5,000 as a UK guide. Businesses in Portsmouth 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.
