Heating & Plumbing for Retail Shops
A shop needs its heating, hot water and any air conditioning working during trading hours, and a closed door during a repair means lost trade.
A shop needs its heating, hot water and any air conditioning working during trading hours, and a closed door during a repair means lost trade. We aim to work around opening times where the fault allows it.
Minimising disruption to trading hours
Where possible we schedule work before opening or after closing, and tell you honestly if a repair genuinely needs the shop closed to complete safely.

Heating and cooling a shop floor
Frequent door opening, shop window heat gain and staff-only back areas all behave differently to a normal room, which affects how heating and cooling are sized.
What we need from you to quote
Trading hours, the layout of the sales floor versus staff areas, and any existing heating or air conditioning equipment.
What helps us plan around trading hours
- Opening and closing times
- Whether the shop has a stockroom or staff area with separate heating
- Existing air conditioning or heating equipment
- Any areas that get notably cold near the entrance

Questions we get asked
Can repairs be done before we open?
Often yes, subject to the fault and access. We will confirm timing before booking.
Why is the front of the shop always colder?
Frequent door opening near the entrance loses heat quickly, which is a layout issue as much as an equipment one.
Do you fit air conditioning in retail units?
Yes, under our REFCOM (F-Gas) registration, sized to the specific layout and heat gain of the shop.
