A walk-in freezer is one of the biggest pieces of kit a Glasgow food business will buy, and most of the work is decided before any panels arrive on site. Whether it's for a takeaway in Shawlands, a butcher in Paisley or a unit on an industrial estate in Hillington, the same questions come up every time: where it will go, what power it needs and what the council needs to know. This guide takes you through each stage so you know what to ask for and can plan around it.
A good installer will visit before quoting. They'll measure the space, check ceiling height and access routes, and ask what you're storing and how much. A freezer built from 100mm or 150mm insulated panels loses a surprising amount of internal space, so a 2.4m by 2.4m footprint gives you roughly 2.1m by 2.1m inside.
Access matters more than people expect in Glasgow. Tenement basements, narrow lanes in the Merchant City and shop units with only a single front door all limit panel sizes and how the job is planned. Panels can be cut to suit, but it needs to be known at the survey stage, not on the day.
In Glasgow, structural or layout changes may need a building warrant from Glasgow City Council, which works under different rules to the building regulations used south of the border. A freestanding cold room inside an existing unit often doesn't need one, but alterations to walls, drainage or fire escape routes can. Check with the council's building standards team before work starts rather than after.
If the condensing unit is going on an outside wall or roof, planning permission may be needed, particularly in conservation areas such as the West End, Park Circus or parts of the city centre. Noise is the usual concern where neighbours live above or beside you. Environmental health will also want to know about significant changes to food storage if you're a registered food business.
Freezers need an insulated floor. Without one, the cold works its way into the ground and can cause frost heave, which lifts and cracks the slab over time. Options include an insulated panel floor with a ramp, or a sunken insulated floor laid flush for trolley access. Larger rooms may also need an underfloor heater mat.
Power is the other common surprise. A small freezer may run on single-phase supply, but larger systems often need three-phase. If your unit doesn't have it, getting an upgrade from the network operator can take weeks, so raise it early. The refrigeration engineer must hold F-gas certification to handle refrigerants, and you should get paperwork confirming the refrigerant type and charge.
For a standard modular room, panel assembly usually takes one to two days. The refrigeration side, including the evaporator, condensing unit, pipework, electrics and controls, takes another one to two days. The system then needs 24 to 48 hours to pull down to temperature before you load it.
Commissioning should include leak testing, checking temperatures hold under the door opening you'd expect in normal trading, and setting alarms. Ask for a handover covering defrost settings, how to read the controller and what to do if the alarm goes.
Prices depend heavily on size, floor type, access and whether new power or planning is involved. As a rough guide, a small walk-in freezer in the Glasgow area might cost around £8,000 to £15,000 installed, with larger or bespoke rooms running from £15,000 to £30,000 or more. Get a written quote that separates panels, refrigeration, flooring and electrical work so you can compare like for like.
Lead times for panels and refrigeration equipment are typically two to six weeks from order. Build in extra time if you need a building warrant, planning consent or a three-phase upgrade.
Not always. A freestanding cold room inside an existing unit often doesn't need one, but structural, drainage or fire escape changes can, so check with Glasgow City Council's building standards team before work begins.
Usually not. The system needs 24 to 48 hours to pull down and stabilise at temperature before you load stock.
Most commercial freezers should be serviced at least once a year, and busy kitchens often go for every six months. Systems above certain refrigerant thresholds also need regular leak checks under F-gas rules.
