- Questions about where the outdoor unit can go
- An oil, LPG or gas boiler near the end of its life
- Checking whether planning permission is needed
How the visit works
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First we check the system or the space against the plan, then the work itself, and finally everything is tested, recorded and explained. The middle part takes longest, which 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. Send pictures of the space and the outside wall, and we can plan the work near Liss.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- The system is installed and connected to the controls.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Getting ready for the visit
- Arrange for someone to be there to let us in
- Tell us about any building rules, permits or sign-in
- Plan for pets to be kept clear during the visit

Advice
Air source heat pumps in Liss
Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. If the problem is ageing boilers that will need replacing and checking whether planning permission is needed, we can sort it out.
Cottages and older homes near Liss can lose heat faster, which a heat loss calculation will show. Sometimes insulating first makes more sense.
We are an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

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’re happy to deal with either side, and the paperwork can go to both.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed-price quote.
What affects the cost of air source heat pumps
We quote each job individually. This is what makes a difference:
- The type of system, from a single split to a larger system
- Whether it’s a one-off job or part of a maintenance contract
- The brand, model and parts involved
One room or a whole building, we price it on the same basis: what needs doing, how we get to it and what it needs. The price is fixed before work begins, and the quote sets out the VAT.
Asking for a quote
When you contact us, these details help:
- The rating plate or label on any existing unit
- Any previous service or F-Gas records
- Where the outdoor unit is, or where you’d like it
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.
Liss questions
Will a heat pump in Liss need planning permission?
It depends on the property. Central Liss is a short walk from the Liss Conservation Area. 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 East Hampshire council, which is usually the planning authority for Liss first.
Is Liss within the area you cover?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us in Liss and across Hampshire. Let us know who the records should go to.
Am I eligible for a heat pump grant?
We confirm eligibility at the survey stage. There’s one grant per property, you cannot get one to replace a low-carbon system, and hybrids are excluded and other conditions apply.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before work begins, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
What VAT do I pay on a heat pump?
Heat pumps in homes carry 0% VAT until 31 March 2027, with 5% from 1 April 2027. It doesn’t apply to businesses, and this is general information rather than tax advice.
What a heat pump looks like in Liss
The last census (2021) found about 71% of households in detached or semi-detached houses. Houses usually have space for an outdoor unit and a hot water cylinder.
Live in one of the older houses around Church of St Mary? Expect the survey to look closely at heat loss and at the building’s planning status. If you live near Liss station, the survey compares air-to-water and air-to-air for your home before anything is quoted.
