Green Cross questions
Is planning permission needed for a heat pump in Green Cross?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 3 buildings and structures within half a mile of the centre of Green Cross. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the local planning authority (for Green Cross, normally Waverley council) first.
Do you cover smaller places like Green Cross?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
How much does an air source heat pump cost?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. The heat pump size, radiator changes and the cylinder decide where in that range you are. Air-to-air is priced after a survey.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Does the grant cover air-to-air heat pumps?
Sometimes, and the amount is £2,500 rather than £7,500. It must replace fossil-fuel heating and meet the full heating demand of a home with an MCS certified installer.
Will skipping a service affect the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim and we will tell you what your brand asks for.
Air source heat pumps in Green Cross, done properly
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. Air-to-air systems don’t heat hot water, so you’ll need another way to do that. Typical jobs include working out where a cylinder could go and checking eligibility for a heat pump grant, across homes heated by oil, LPG or gas, underfloor heating and air-to-air heat pumps.
Older and listed homes in villages like Green Cross need extra care, because permitted development does not apply within the grounds of a listed building, so consent comes first.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Leave it or put it right?
Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. Planning ahead gives time for the heat loss survey, the design and the grant application while the old heating still works. Booking before summer means the work in Green Cross is done before the hot weather.
The pipe route, the height of the units and how we reach them can all change the price. Each of those is built into the quote and give you a fixed price before we start.

How the visit works
On the day, we arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. The work itself takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Photos of the room and the outside of the property help us plan a visit to Green Cross.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
Before we arrive
- Clear the space around the indoor unit, or where it will go
- Name a contact who can meet us at the agreed time
- Keep pets out of the rooms we are working in

Advice
What we’re called out for in Green Cross
Extensions, renovations and loft conversions are a natural time to rethink the heating. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.
Any of these is worth a proper look:
- Questions about where the outdoor unit can go
- A boiler that’s getting old
- Working out whether radiators need upsizing
A heat loss calculation decides the size of heat pump your home needs.
What your quote should include
- What paperwork you will receive afterwards
- What the manufacturer’s warranty covers and for how long
- Whether testing, commissioning and paperwork are included
Safe owner checks
Don’t move, re-route or disconnect units or pipework yourself. 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.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
