Air source heat pumps in St Cross
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb isn’t good enough. If you are dealing with planning and permitted development questions and deciding which kind of heat pump suits the home, we can help.
Whether a home near St Cross has mains gas makes a difference to the grant. Until March 2027, homes on oil or LPG without mains gas can get an extra £1,500 through the Boiler Upgrade Scheme.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

Leave it or put it right?
The extra £1,500 for homes heated by oil or LPG with no mains gas is available until March 2027. For homes that qualify, that is a reason to look into it now. A system that’s left with a fault, or without a service, typically costs more to run.
A single unit or a whole estate, the quote is built the same way: what needs doing, how we get to it and what it needs. You will have a fixed price before work begins, and the quote sets out the VAT.

St Cross questions
Will a heat pump in St Cross need planning permission?
It depends on the property. The centre of St Cross is in the Winchester Conservation Area. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for St Cross, normally Winchester City council).
Is St Cross within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and photos, and we reply the same working day.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for breakdowns that can’t wait. Ring 07833 053749 any time and explain the problem.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Is the equipment covered by a warranty?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition, so keep your service records.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.

Landlords, agents and facilities managers
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We can quote either party, and the paperwork can go to both.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system and we are happy to deal with whoever it is.

What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then we do the work, and finally we test, record and explain. The middle part takes longest, which takes from a couple of days to around a week, depending on the system and how much of the heating changes. Send pictures of the space and the outside wall, and we can plan the work near St Cross.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Commissioning, MCS certification and a handover of the controls finish the job.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Let us know where we can park and unload
- Name a contact who can meet us at the agreed time

Advice
What owners can safely do
Owner care supports servicing; it doesn’t replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
From one of our customers
“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.”
