About our air source heat pumps in Fratton
We begin with a room-by-room heat loss survey. That tells us how much heat the home needs, room by room, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. Common call-outs are for not knowing whether a grant applies and working out whether radiators need upsizing, across homes heated by oil, LPG or gas, radiator systems and air-to-water heat pumps.
Homes around Fratton usually have space for an outdoor unit and a hot water cylinder, so the main questions are heat loss, radiators and the electrics.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Safe owner checks
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call us on 07833 053749, or email if that’s easier.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
Heat pumps in Fratton: local notes
At about 2 miles from the coast, Fratton is close enough for sea air to matter. Coastal sites are worth mentioning at the survey, as salt air affects the outdoor unit and its fixings. There are 6 conservation areas within a mile of the centre of Fratton. On the National Heritage List, around 14 entries fall within 0.5 miles of the middle of Fratton; Church of St Mary (grade II*) is one. Where a home is affected, the outdoor unit position is settled with the local planning authority (normally Portsmouth council) before the heat pump design is finished. Valuation Office Agency council tax records put about 57% of homes across Fratton and its surrounding area before 1919, and about 57% of households live in terraced houses, according to the 2021 Census. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. In a terrace, the outdoor unit position and the MCS noise check need particular care.
Live in one of the older houses around St Mary's Church? Expect the survey to look closely at heat loss and at the building’s planning status. For a home near Fratton station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.

Questions from Fratton
Does sea air affect air conditioning in Fratton?
It can, as Fratton is within about 2 miles of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Is Fratton within the area you cover?
Yes. Fratton is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for breakdowns that can’t wait. Call 07833 053749 and tell us what’s happened.
Should I choose air-to-water or air-to-air?
The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions, and we set out the options after the survey.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. 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 can tell you which band your system falls into.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
Why use an F-Gas certified company?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before you book and we’ll gladly show you ours.

Why deal with it now?
A sudden boiler failure rarely leaves room to plan a heat pump properly. Surveying and designing in advance means the system is sized right and any grant is applied for before you need the heat. A dirty or faulty system works harder and costs more to run.
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.
What you get with us
- Diagnosis first, then a fixed price
- MCS certification for heat pump work
- Members of Checkatrade
- Manufacturer’s warranty terms explained on your quote

What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. The visit takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. Around Fratton, access is usually simple, though gates and garden access are worth mentioning.
- First we find out about the property, the heating you have now and what you are hoping for.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Tell us about any building rules, permits or sign-in
- Let us know where we can park and unload
Getting a quote
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.
