Whempstead: your questions answered
Will you come out to Whempstead?
Yes. Whempstead is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Will air conditioning in Whempstead need planning permission?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Whempstead holds about 5 listed buildings and structures. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at East Hertfordshire council, usually the authority for Whempstead.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Which accreditations do you hold?
As the law requires for refrigerant work, we are an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Do I need a new electrical circuit?
Most systems need their own supply from the consumer unit. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and we are NICEIC approved, so we can install and certify it.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, 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.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.

A single room takes a day in most homes, with multi-room systems taking longer depending on pipe routes.
Homes around Whempstead normally have room outside for an outdoor unit. The questions are more often the age of the walls, the electrics and how far the pipes need to run.

Looking after your system
Simple habits make a real difference. We recommend:
- Keep the indoor unit’s filters clean
- Do not cover or box in the outdoor unit
- Choose a comfortable set temperature rather than the lowest
The work area is left tidy: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Pipework outside is covered in trunking or insulated and neatly fixed as agreed on the survey.
Use sensible settings. A moderate set temperature cools the room just as well as the lowest one, without the waste, and close windows and doors while it’s cooling.
Do you need air conditioning in Whempstead?
Most overheating comes from heat gained through 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.
What we’re most often called about:
- A study or office that overheats during the day
- A system on old refrigerant that’s due for replacement
- A portable unit with a hose out of the window
Living close to Parish Church of All Saints? Some older properties in parts like that are protected, and the survey finds out whether yours is.

How the job changes from property to property
Electrical supply
A dedicated circuit is normally needed. As NICEIC approved contractors, we install it and issue the certificate, which takes care of the Part P notification.
Ceiling cassettes
Cassettes need space above the ceiling and a route for the condensate, and many use a built-in condensate pump to lift the water away. The survey confirms the void and the drain route.
Homes in Whempstead and air conditioning
Census 2021 figures found about 76% of households in detached or semi-detached houses. Detached and semi-detached houses typically have space for the outdoor unit, and several rooms can share one on a multi-split.
With historic houses such as Aston Bury about 2.6 miles west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

What we do, step by step
Think of the visit in three stages: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that takes a day or more, depending on the number of rooms, the pipe routes and the access. Visits to Whempstead are agreed with you in advance and planned so the job can be finished in one trip where possible.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
How to prepare
- Have the make and model of any existing unit to hand
- Keep pets and children away from the work area
- Arrange for someone to be there to let us in
