Air source heat pumps in Longstock
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems don’t heat hot water, so you’ll need another way to do that. The work covers radiator systems, hot water cylinders and air-to-air heat pumps, and the jobs we see most are checking whether planning permission is needed and deciding on the outdoor unit position.
Older and listed homes in villages like Longstock need extra care, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

Your questions about air source heat pumps in Longstock
Is planning permission needed for a heat pump in Longstock?
The answer turns on the property and where the outdoor unit would sit. The Longstock Conservation Area is close to the centre of Longstock. 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 planning department at Test Valley council, normally the authority for Longstock first.
Do you cover smaller places like Longstock?
Yes, and the size of the place makes no difference to how we work. A few pictures and the postcode are enough to get things started.
Do I get paperwork after the visit?
Yes. Every visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before we start, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
How much time does a heat pump install need?
An installation takes from a couple of days to around a week, depending on the system and how much of the heating changes. We confirm the timing after the survey, so ring 07833 053749 or fill in the contact form to arrange one.
What the work involves, system by system
Air-to-air heat pumps
Air-to-air heat pumps are now covered by permitted development rules in England, subject to conditions. Cooling-only units are not included and need a check with the council.
Radiators and underfloor heating
Any radiator changes are set out in the quote, so you know the full scope.
Safe owner checks
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
What affects the quote in Longstock
Your quote is based on your property. We take into account:
- The equipment or parts the job needs
- The size of the job
- What kind of system it is
A single unit or a whole estate, the quote is built the same way: the work involved, the access and the equipment. The price is fixed before work begins, with VAT shown clearly.
Helping us quote
When you contact us, it’s useful to have:
- A short video of any fault, such as a noise or a flashing light
- The paperwork from the last service, if you have it
- A photo of the consumer unit with the cover closed
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. Tell us the address and what you need, and many jobs can be priced from that.

Air source heat pumps around Longstock
About 85% of households live in detached or semi-detached houses, according to the 2021 Census. Houses usually have space for an outdoor unit and a hot water cylinder.
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler. 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.

How it works
Each visit follows the same order: check the plan with you, put the dust sheets down, do the work, check the system and talk you through it. The visit itself 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. Somewhere like Longstock, it helps to know about lanes, gates and where to park.
- It starts with a conversation about the home, the existing heating and your plans.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- Installation covers the outdoor unit, the indoor connections and the controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
Preparing for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Make sure we can reach the consumer unit or fuse board
- Let us know where we can park and unload
