How a job in Walthamstow works

  1. Survey

    We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go.

  2. 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.

  3. First fix

    Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung. In Walthamstow we agree timings around your opening hours.

  4. Install and test

    Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.

  5. 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

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.

Access and parking

Town-centre jobs in Walthamstow often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.

Condensate

Every cooling unit produces water. We route it to a drain by gravity where possible and fit a quiet condensate pump where not.

Shared buildings

In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.

Typical premises in Walthamstow

  • 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).
