Commercial air conditioning in Newnham
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor; we’re not assessors, but we prepare systems for inspection and act on what the report finds. Typical jobs include TM44 recommendations that need acting on and planning ahead for the HFC phase-down, on VRF systems, ducted systems and multi-split systems.
Around Newnham, commercial jobs tend to be pubs, shops, halls, surgeries and farm or rural businesses. Older buildings may be listed or in a conservation area, so we check the planning side first.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual so it’s to hand next time.

- We recommend a system and send a fixed-price quote.

Advice
Cooling for Newnham businesses
There are about 5 restaurants, cafés and canteens within about 1.5 miles of central Newnham, according to the Food Standards Agency’s register. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use.
If you run a surgery, clinic or pharmacy in the area around Fairfield Hospital, about 3 miles south-west, cleanable, quiet units and regular maintenance matter.
Newnham is about 3 miles north-east of Letchworth, in Hertfordshire.

Your questions about commercial air conditioning in Newnham
Is planning permission needed for air conditioning in Newnham?
That depends on the building and where the outdoor unit goes. The Newnham Conservation Area takes in the middle of Newnham. 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 is not allowed under those rules. If there’s any doubt, we ask the local planning authority (for Newnham, usually North Hertfordshire council).
Is Newnham in your area for commercial air conditioning?
Yes. Newnham is one of the places we cover. Get in touch with the details and we reply the same working day.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking, and we’re happy to show ours.
Does my building need a TM44 inspection?
Where the air conditioning is over 12 kW, an inspection is needed at least every 5 years. An accredited energy assessor carries it out, and we can prepare the system and act on the report.
How are commercial air conditioning installs priced?
Each commercial job is surveyed and then priced. It means the system and the programme fit your building, and the quote you get is fixed.
Can I do any of the installation myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
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.
Honest limits
We will not sell you work that doesn’t address the problem, so here are the limits:
- Major builder’s work such as new openings in structural walls
- Planning permission or landlord consent on your behalf
- Fire strategy sign-off
Not sure which it is? You can phone 07833 053749, or email if that’s easier and we will tell you honestly before booking.

What we are called out for in Newnham
Schools and public buildings often need work done in the holidays. We plan installs for holidays and weekends to keep teaching undisturbed.
Most people get in touch after spotting one of these:
- TM44 recommendations that need acting on
- Older systems that can’t keep up
- Leak check schedules that have slipped
Churches and halls such as Church of St Vincent are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.
Comparing quotes

- What the manufacturer’s warranty covers and for how long
- Which VAT rate the quote uses, and why
Leave it or put it right?
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. Getting the date in early helps for a place like Newnham.
