Common questions in Little London
Can I fit a heat pump in Little London without planning permission?
That depends on the building and where the outdoor unit goes. Historic England lists about 12 buildings and structures within half a mile of the centre of Little London. 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 Mid Sussex council, which is typically the planning authority for Little London.
Can I get the Boiler Upgrade Scheme grant in Little London?
Little London is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. The installer applies, and we’re MCS certified.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
Are my radiators big enough for a heat pump?
We find out during the survey. Rooms where the radiator is big enough stay as they are and any changes are in the quote.
Will I get records for the system?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. For instance, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
Air source heat pumps in Little London
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. Guesswork leads to systems that are too big or too small. The work covers air-to-water heat pumps, homes heated by oil, LPG or gas and radiator systems, and common reasons people get in touch are no space for a hot water cylinder and moving away from fossil-fuel heating.
If your home in or near Little London is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

VAT on heat pumps
Please treat this as general guidance rather than tax advice.
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. Noise is part of the MCS 020(a) check, so we consider nearby homes too.

After we’ve gone
Think of this as the after-treatment advice, in brief:
- Diary the next service
- Find out the grant position at the survey
- Store the MCS certificate and warranty documents together
Should you have questions after the install, ring 07833 053749 and we will talk it through. A yearly service is a good habit.
Don’t cover radiators with furniture or heavy curtains so the heat can get into the room.
How it works
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 everything is tested, recorded and explained. Most of the time goes on the middle part, which takes a few days for most air-to-water installations, with air-to-air systems often quicker. A few photos help us make the most of a visit to Little London.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Name a contact who can meet us at the agreed time
- Have the make and model of any existing unit to hand
- Mention any roof access, ladders or high-level work
How to get a quote
Every quote shows the VAT clearly, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. To get one, phone us on 07833 053749 or send an email.

Common problems we fix in Little London
Homes with electric heating sometimes look at heat pumps as an alternative. The survey tells you whether it’s practical and what’s involved, and we explain the grant position for your home.
Keep an eye out for any of the following:
- Questions about listed buildings or conservation areas
- Working out where a cylinder could go
- Working out whether radiators need upsizing
If your home is listed, like Priest House about 1.8 miles north-east, listed building consent comes before any heat pump work.
Comparing quotes
- Whether the quote is a fixed price
- Which VAT rate the quote uses, and why
- Whether anyone has checked the property or the system first
What a heat pump looks like in Little London
About 79% of households live in detached or semi-detached houses, according to Census 2021 figures. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder.
Older homes near St Peter's Church may need extra checks for planning and heat loss before a heat pump is designed.
