Commercial air conditioning in Wennington, done properly
Commercial air conditioning comes with F-gas duties for the operator. Leak checks and records are required for systems from 5 tCO2e upwards. We carry out the checks, keep the records and tell you when the next one is due. If you are dealing with staff complaining about the temperature and older systems on refrigerants that are getting scarcer, we can sort it out.
In Wennington, as anywhere in England, larger systems need F-gas leak checks, and over 12 kW of cooling a TM44 inspection is required. We keep the records and tell you what’s due.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Common questions in Wennington
Is Wennington in your area for commercial air conditioning?
Yes. Wennington is one of the places we cover. Just call 07833 053749, or email if that’s easier with a few details.
Will air conditioning in Wennington need planning permission?
That depends on the building and where the outdoor unit goes. Historic England lists about 3 buildings and structures within half a mile of the centre of Wennington. 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 local planning authority (for Wennington, normally Havering council).
What are the F-gas responsibilities for commercial air conditioning?
The duties depend on how much refrigerant the system holds. Systems at or above 5 tCO2e need leak checks and records with automatic leak detection at 500 tCO2e and above.
How much does commercial air conditioning cost?
Every commercial job is priced after a site survey. The cost depends on the size of the space, the system and how the work is phased, and you get a fixed-price quote before work starts.
Do you look at the job first?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for breakdowns that cannot wait. Call 07833 053749 and tell us what’s happened.
Are you TM44 assessors?
An accredited energy assessor has to carry out the inspection, and we’re not assessors. We prepare systems for inspection and carry out the work the report recommends.
Cooling for Wennington businesses
The FSA’s food hygiene register shows about 23 cafés, restaurants and staff canteens, about 8 schools and colleges and about 11 care homes, nurseries and hospitals within about 1.5 miles of central Wennington. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. About 47% of homes in and around Wennington were built between the wars, according to Valuation Office Agency council tax records, and the 2021 Census found about 37% of households in terraced houses. In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind. For London businesses, plant position, noise and access are planned with the building first.
Schools such as Brady Primary School normally have the work done in the holidays, when classrooms are empty.

Common problems we fix in Wennington
Restaurants and hotels need comfortable rooms for guests and staff. Each area has its own hours and heat load, which affects the type of system and controls we’d suggest.
These are the situations we see most often:
- New tenancies needing cooling and heating
- Staff complaining about the temperature
- Installs that must fit around trading hours
If you run a surgery, clinic or pharmacy in the area around St George's Hospital, about 2.8 miles north, cleanable, quiet units and regular maintenance matter.
What your quote should include
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Whether the manufacturer’s warranty depends on regular servicing
- Exactly what the price includes, from supply and fitting to commissioning
Leave it or put it right?
A system that cannot cope on the hottest days affects everyone in the building. It’s far easier to plan new work in the cooler months than to scramble when it’s hot. Consents in London blocks can take time, which is another reason to plan the job in Wennington early.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you’re unsure, phone 07833 053749 or use the quote form for straight advice and a fixed price.
Why us?
- One contact for properties across the South East and London
- Fixed-price quotes after a survey or pictures
- Clear warranty information from the manufacturer
- Electrical work covered by our NICEIC approval

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
