- Questions about the Boiler Upgrade Scheme
Looking after your system
To keep the system working properly:
- Avoid switching the heat pump on and off often
- Look at insulation alongside the heat pump
- Leave space around the outdoor unit
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes, and that is normal.
Book a service every year. Check the manufacturer’s terms, as they may include servicing conditions.
Air source heat pumps in Portswood, done properly
We begin with a room-by-room heat loss survey. That tells us how much heat the home needs, room by room so the system is sized to match. Guesswork leads to systems that are too big or too small. If you’re dealing with ageing boilers that will need replacing and replacing a combi boiler with a heat pump, we can help.
If your home near Portswood has no mains gas, the grant can be bigger. Until March 2027, homes on oil or LPG without mains gas can get an extra £1,500 through the Boiler Upgrade Scheme, for an air source or ground source heat pump.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

What a heat pump looks like in Portswood
The coast is only about 2 miles from Portswood. Coastal sites are worth mentioning at the survey, as salt air affects the outdoor unit and its fixings. Portswood’s centre is no more than about a third of a mile from the Portswood Residents' Gardens Conservation Area. 5 conservation areas lie within a mile of central Portswood. Listed buildings are part of the picture here: about 9 within half a mile of the centre, such as The Dutch House (grade II). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area? About 43% of homes in the Portswood area were built before 1919, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 49% of households live in flats. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. A flat may have no room for a hot water cylinder, and the freeholder typically has a say on the outdoor unit, which can tip the choice towards air-to-air.
Live in one of the older houses around Highfield Church? Expect the survey to look closely at heat loss and at the building’s planning status. If your home is listed, like South Stoneham House about 1 mile north-east, listed building consent comes before any heat pump work.

Advice
Different systems, different jobs
The Boiler Upgrade Scheme
Only one grant is available per property, and it cannot replace a low-carbon system, and hybrid systems are not eligible.
VAT on heat pumps
Heat pumps in homes carry 0% VAT until 31 March 2027, and 5% after that following HMRC’s rules on energy-saving materials. Businesses pay the standard rate.
Common questions in Portswood
Can I get the Boiler Upgrade Scheme grant in Portswood?
Portswood is in England, where the Boiler Upgrade Scheme runs. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. As an MCS certified installer, we apply for it on your behalf.
Does being near the sea make a difference to air source heat pumps in Portswood?
It can, as Portswood is within about 2 miles of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Do I need new radiators for a heat pump?
Some radiators may be fine as they are, and some may need to be larger. At the lower temperatures a heat pump uses, radiators need more surface so we check every radiator against the room’s heat loss.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Do you look at the job first?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Pricing air source heat pumps in Portswood
You’ll get a fixed price before any work starts. It’s based on:
- The equipment or parts the job needs
- What electrical work the job needs
- What we find on the survey or diagnosis
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. You get a fixed price before work begins, so you know where you stand.
What we need to know
You do not need the technical terms. It helps if you can send:
- Where the property is and what kind of building it is
- Where the outdoor unit is, or where you’d like it
- The fuse board and where it is in the property
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
