Not sure what you need, or where it would go? Just call 07833 053749 with photos of the rooms and the outside of the property, and we’ll reply the same working day to arrange a survey or a quote. Most split systems we fit in Frithsden are reversible: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, which is why many owners use theirs all year.
Around Frithsden, many people choose a system that heats as well as cools, which suits rooms the main heating does not reach well, such as a garden room or loft.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Questions from Frithsden
Is planning permission needed for air conditioning in Frithsden?
That depends on the building and where the outdoor unit goes. The centre of Frithsden is in the Frithsden Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the planning department at Dacorum council, normally the authority for Frithsden.
Is Frithsden in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Frithsden is part of that. To start, ring us on 07833 053749 or email us with a few pictures.
How soon will you get back to me?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
What does it cost to install air conditioning?
For one room, a split system is typically £1,200–£2,200 + VAT. Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, including supply, installation, commissioning and F-Gas documentation. The price is fixed before we start.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.

What we’re called out for in Frithsden
Rooms overheat mostly because of heat they gain during the day. Sun through large windows, roof lights and glazed doors is the biggest source in many rooms, and once the room has warmed up, it holds on to it into the evening.
Keep an eye out for any of the following:
- A room that’s unbearable on warm days
- An old system that needs replacing
- A business premises that overheats in summer
If your home is in one of the older streets near Church of St Lawrence, it’s worth checking whether it’s listed or in a conservation area before an install.

- Whose warranty applies, and on what terms
What happens on the day
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. For a village like Frithsden, tell us about narrow lanes, gates and parking when you book.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
How to prepare
- Plan for pets to be kept clear during the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Clear access to the fuse board

Advice
Homes in Frithsden and air conditioning
About 73% of homes in and around Frithsden date from 1945 to 1972, according to VOA council tax data, and the 2021 Census found about 52% of households in terraced houses. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. With a terrace, the back wall or an extension roof is usually the best place for the outdoor unit.
Bedrooms under the roof and rooms with big sunny windows are typically the first to overheat, so they’re the usual place to start.
