When to call us in Round Bush
In shops, offices and restaurants, the heat comes from customers, staff, equipment and lighting as well as the sun. Keeping staff and customers comfortable is typically what prompts the call, and some rooms need cooling for the equipment as much as the people.
Keep an eye out for any of the following:
- Uncertainty over the right type and size of system
- An ageing air conditioning system near the end of its life
- Commercial rooms that are too warm for staff
About 2.9 miles north-west stands High Elms Manor. Listed homes in any area need consent first, so tell us if yours is one.
Before booking anyone
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- What’s in the price and what is not
- If the quote is based on a survey, pictures or a diagnosis

What happens on the day
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes anything from a day for one room to several days for a multi-room or ducted system. Photos of the room and the outside of the property help us plan a visit to Round Bush.
- You send pictures, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- The system is commissioned, the controls explained and the F-Gas records handed over.
Before we arrive
- Let us know where the consumer unit is
- Let us know if the building has a permit or sign-in process
- Unlock any gate, garage or side passage we need

Why act early in Round Bush
The outdoor unit’s position is worth getting right first time. Placing it well keeps noise away from bedrooms and boundaries and makes servicing easier, and it can make a difference to planning. It’s agreed on the survey, not on the day. A system that’s left with a fault, or without a service, normally costs more to run.
One room or a whole building, the quote is built the same way: the work involved, the access and the equipment. You will have a fixed price before any work starts, with VAT shown clearly.

Round Bush: your questions answered
Do I need planning permission for air conditioning in Round Bush?
It depends on the property. The Round Bush Conservation Area takes in the middle of Round Bush. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t 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 Hertsmere council, which is usually the planning authority for Round Bush.
Can you do air conditioning in Round Bush?
Yes, Round Bush is within the area we cover. To start, call 07833 053749 or fill in the contact form with a few photos.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Do you work on all makes?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Are you F-Gas certified?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Do you look at the job first?
Yes, every time. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Air conditioning in Round Bush: local notes
About 71% of households live in detached or semi-detached houses, according to Census 2021 figures. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
Homes near Church of St John the Baptist are a good example of where we look up the heritage status of the building before fixing anything to it.
