The process
The first job on site is protection: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. The work on site takes anything from a day or two for a small office to several weeks of phased work on a large building, and we clear up before we go. In a London area like Dollis Hill, parking and access are worth sorting out before the day.
- We start with the details of the building and the problem.
- A site survey confirms the heat load, the layout and the access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where needed.
- The system is commissioned and maintenance can be arranged.
Preparing for the visit
- Clear the space around the indoor unit, or where it will go
- Mention any parking restrictions near the property
- Keep pets and children away from the work area

Advice
Commercial air conditioning in Dollis Hill
There’s no single best commercial system. Splits for small rooms, cassettes for open-plan ceilings, ducted for a hidden finish and VRF or VRV for many zones on one system. We explain the options and why we’d choose one over another. Typical jobs include systems over 12 kW due a TM44 inspection and commercial systems near the end of their life, across ducted systems, server and comms room cooling and ceiling cassettes.
Space for outdoor units is tight in much of London, Dollis Hill included, so roofs, light wells and basements are common positions. VRF systems keep outdoor plant down by serving many rooms from few outdoor units, which helps in dense areas.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Dollis Hill: your questions answered
Can I fit air conditioning in Dollis Hill without planning permission?
It depends on the property. A conservation area takes in the middle of Dollis Hill. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with Brent council, which is typically the planning authority for Dollis Hill.
Do you cover Dollis Hill for commercial air conditioning?
Yes, Dollis Hill is within the area we cover. Just ring us on 07833 053749 or drop us a line with a few details.
What are the F-gas responsibilities for commercial air conditioning?
The operator and the service technicians share responsibility. The operator must make sure leak checks are done where required and records are kept and we handle that for you.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
How often is a TM44 inspection needed?
If the air conditioning has an effective rated output over 12 kW, an inspection is required at least every 5 years. GOV.UK has guidance on how it works, and we can help you prepare.
Are you TM44 assessors?
TM44 inspections are carried out by accredited energy assessors, which we are not. We prepare systems for inspection and carry out the work the report recommends.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Why it’s worth doing now in Dollis Hill
R410A systems are still legal to repair, though supply of the gas is tightening. Planning a replacement on your own timetable beats replacing it after a major failure. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Dollis Hill early.
