Business spaces
Tell us the working context: opening hours, customer areas, access limits, current units, landlord requirements, and parking or access for the work.
Typical projects
These examples help customers recognise the kind of enquiry they are making before comparing equipment tiers or assuming a single headline price.

Usually the clearest starting point: one indoor unit, one outdoor unit, and a path that can be checked from photos.

The decision is not just room count. Pipe routes, simultaneous use, outdoor capacity, and service access all need a closer look.

Commercial timing, customer disruption, existing labels, and access risk can affect the work as much as equipment choice.
Match the business constraint
Small business projects need a practical plan before final pricing because disruption, customer areas, landlords, and replacement timing can matter as much as capacity.
Share opening hours, customer areas, protection needs, and when work can happen without disrupting trade.
Show current units, labels, controller messages, and whether temporary cooling or staged work is needed.
Note permissions, external-unit restrictions, loading limits, roof or rear access, and any noise-sensitive neighbours.
Shops, offices, clinics, hospitality spaces, and similar commercial rooms.
Business-hours limits, access, parking, landlord consent, building management, and replacement complexity.
Room layout, current units, plant location, outside wall, access path, and fuse board.
Out-of-hours work, permissions, and commercial site constraints are checked before final pricing.
Before you send it
A clear first request helps Trust AC check the site faster and keeps the next step practical.
Yes. Out-of-hours and phased work is normal for shops, offices and hospitality, and we price it that way when it is needed rather than disrupting your trade.
That depends on access and how the space is used. We agree the programme up front — which areas, which days, what stays open — so it is planned rather than discovered.
Yes. Multi-room and building-wide work, and specialist sectors such as data centres, pharmaceutical and cold storage, are covered by our large-projects service.
