Wallington: your questions answered
Will you come out to Wallington?
We do. Villages and hamlets get the same service as the bigger towns. A few photos and the postcode are enough to get things started.
Do I need planning permission for air conditioning in Wallington?
The answer turns on the property and where the outdoor unit would sit. Central Wallington sits inside the Wallington Conservation Area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Wallington, usually North Hertfordshire council) when it matters.
Do I get paperwork after the visit?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
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.
Do you carry out TM44 inspections?
We are not accredited energy assessors, so we don’t inspect. We can prepare for the inspection and put right what it finds.
Who is responsible for leak checks?
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 yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
How we handle commercial air conditioning in Wallington
The business that operates the system has F-gas responsibilities. Systems at or above 5 tCO2e need leak checks, and records kept of the checks and the work done. We carry out the checks, keep the records and tell you when the next one is due. The work covers VRF systems, server and comms room cooling and ducted systems, and the jobs we see most are systems over 12 kW due a TM44 inspection and workspaces that overheat on warm days.
For a business near Wallington, outdoor units typically have room at the back of the building.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

The process
You do not need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. Before we leave, the area is tidied and we explain what we have done. For a place like Wallington, the timing is set with you and the travel is our side of the planning.
- It starts with a survey on site, looking at the space, the people in it and the equipment.
- A fixed-price quote follows, covering the system type, the layout and the timing.
- The work is planned around your opening hours, with out-of-hours or phased work where it helps.
- Indoor and outdoor units, pipework, condensate and controls are installed and the electrics connected.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
Getting ready for the visit
- Let us know where the consumer unit is
- Unlock any gate, garage or side passage we need
- Tell us about access, such as roof hatches, high walls or locked plant areas
Getting a price
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.

Different systems, different jobs
Ceiling cassettes
A cassette needs space above the ceiling and a route for the condensate. Many include a pump to move the water away and that is checked when it’s serviced.
VRF and VRV systems
With VRF or VRV, one set of outdoor units serves many indoor units. Each zone can be controlled separately making it a common choice for larger buildings.
Do you need commercial air conditioning in Wallington?
Ageing systems are a common reason for a call. Spares get scarce and performance drops, and replacing it becomes the better option.
Customers normally contact us when they notice one of these:
- Changes of use that need a new layout
- Server rooms running too warm
- TM44 recommendations that need acting on
Before any plant goes outside a building like Church of St Mary, its trustees may need planning or heritage advice, and we work with whoever gives it.
