Working in Chiswick
Chiswick sits within London's dense commercial fabric: shopfronts, offices above, studios and venues, where outdoor unit positions and access need careful planning.
We cover every Chiswick postcode, including W4. Nearby, we also cover Acton (about 2 km), Barnes (about 2 km) and Shepherds Bush (about 3 km). 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.
What the job covers
- Room-by-room heat gain and heat loss calculations
- System options with pros, cons and budget costs
- Layout drawings for units, pipework and condensate
- Noise data for planning or landlord approval
- Written specification for pricing

Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
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.
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Working hours
Most Chiswick businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
