Where we work around Dagenham

That includes premises in RM10 and the surrounding districts. We also work in nearby Romford, Hornchurch and Barking. Buildings across London range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

The steps for a project in Dagenham
Survey
We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go. For sites in Dagenham we confirm access and parking beforehand.
Design and quote
You get a written specification with unit sizes, positions, pipe routes and a fixed price — plus any planning, landlord or noise points to resolve first.
First fix
Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung.
Install and test
Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.
Commission and hand over
We set up controls, check air flows and temperatures, show your team how to use it and hand over the F-gas and commissioning paperwork.
Local points to consider
Power
Larger systems need a dedicated supply from the distribution board. We check capacity at survey so there are no surprises on install day.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Planning and noise
Outdoor units on commercial buildings often need planning permission — particularly on a front elevation, in a conservation area or on a listed building — and councils may ask for a noise assessment.
Leased premises
If your Dagenham premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Types of premises we cover in Dagenham
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).

Which postcodes do you cover in Dagenham?
All of them, including RM10. Give us your postcode when you enquire and we will confirm the visit details.
Which refrigerant will you use?
In Great Britain, new single split systems holding less than 3 kg of refrigerant cannot use a refrigerant with a global warming potential of 750 or more, so most are now R32. Larger systems may use R32, R454B or R410A depending on the equipment. We state the refrigerant and charge in the quote.
Is the survey free?
Yes. The site survey and written quote for a new installation are free and there is no obligation to go ahead.
