Littleworth: your questions answered
Is the heat pump grant available in Littleworth?
Littleworth is covered, as the scheme runs across England and Wales. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. We hold MCS certification, so the application is ours to make for you.
Is a heat pump in Littleworth permitted development?
There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Littleworth holds about 17 listed buildings and structures. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Littleworth, typically Horsham council).
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Will I get records for the system?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Do you cover Littleworth?
Yes. Our engineers work in Littleworth, as part of our area across London and the South East. Our base is in East Grinstead, West Sussex.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Air source heat pumps in Littleworth, done properly
Every installation starts with a heat loss survey. That tells us how much heat the home needs, room by room so the system is sized to match. Sizing by rule of thumb is not good enough. If the problem is finding a place for the outdoor unit and wanting to stop using oil, LPG or gas for heating, we can sort it out.
For a home around Littleworth that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

Heat pumps in Littleworth: local notes
The 2021 Census found about 74% of households in detached or semi-detached houses. Houses normally have space for an outdoor unit and a hot water cylinder.
Older homes near St Michael and All Angels Church may need extra checks for planning and heat loss before a heat pump is designed. A heat loss calculation decides the size of heat pump your home needs.

What we do, step by step
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. 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. Seeing the property in pictures first means the trip to Littleworth can be planned properly.
- First we talk through the property and the current system.
- A heat loss survey is carried out, room by 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.
- We install, commission and register the system under MCS.
Before we arrive
- Unlock any gate, garage or side passage we need
- Move furniture away from the wall where we’ll be working

Heat loss surveys
Getting the survey right avoids undersized or oversized systems and that matters for comfort and running.
Hot water cylinders
Hot water from an air-to-water system is stored in a cylinder. The survey looks at where it can go, especially if you have a combi boiler.

What else we do in Littleworth
Why act early in Littleworth
From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. If you are thinking about a heat pump, that date is worth knowing, though the right time also depends on your home and heating. A system that is left with a fault, or without a service, normally costs more to run.
The cost depends on the type of system and how many units are involved, the access and what the work involves. You get a fixed price before we start, so there are no surprises.
