Quick Answer
A catering trolley moves food, crockery, and trays safely around a venue. A 3-tier stainless service trolley costs £89–£168 and suits front-of-house clearing; a 10–15 tier tray rack trolley at £272–£285 holds GN 1/1 trays for kitchens and bakeries. Hot food must stay at 63°C or above in transit.
Caterzone supplies catering trolleys and tray rack trolleys to UK hotels, event caterers, care homes, bakeries, and restaurants, and the humble trolley is the piece of equipment most likely to be bought on price and regretted within a month. A trolley that flexes under load, has castors that jam on a threshold, or is 30mm too wide for the service door is dead money.
This guide explains the main trolley types, how tray pitch and gastronorm compatibility work, what castor and load specifications actually mean, the UK food safety rules that apply when you move hot and cold food, and how to choose between folding and fixed frames. Browse the catering trolley range as you read.
What types of catering trolley are there?
There are four distinct families, and they solve different problems.
Service trolleys are the classic two or three-tier trolleys used front of house for clearing, room service, drinks, and buffet replenishment. They are typically 800mm to 900mm long, with shelves 250mm to 350mm apart, and carry crockery, glassware, and covered dishes.
Tray and rack trolleys carry gastronorm trays or bakery trays on runners. They come in 10, 15, and 20 tier configurations and live in kitchens, bakeries, and prep areas, feeding ovens, blast chillers, and prep counters.
Folding trolleys are service trolleys with a collapsible frame, aimed at event caterers and venues with limited storage. They trade a little rigidity for the ability to fit six trolleys in the back of a van.
Specialist trolleys cover everything else: plate dispensers, cutlery trolleys, hot cupboard trolleys with a heated base, and dirty-crockery clearing trolleys with a bin aperture.
Most UK sites need two: a service trolley for front of house and a tray rack for the kitchen. Buying one trolley to do both jobs usually results in a compromise that suits neither.
How do tray rack trolleys and tray pitch work?
A tray rack trolley is defined by three numbers: tray size, tier count, and pitch. Get all three right and the trolley slots into your workflow; get one wrong and it is scrap metal on castors.
Tray size is usually GN 1/1 (530mm x 325mm) for kitchens, or 600mm x 400mm for bakery trays. Rack trolleys are built for one or the other, and the runner spacing is not interchangeable. Check what your oven, blast chiller, and prep counter actually use before ordering.
Tier count sets capacity. A 10-tier trolley is a manageable height for most staff and suits restaurant prep and service. A 15-tier holds up to 30 GN 1/1 trays when double-loaded and suits bakeries and production kitchens. A 20-tier is a production tool and, when loaded, is heavy enough that route and floor surface become real considerations.
Pitch is the vertical gap between runners, typically 60mm to 80mm. Tight pitch maximises tray count but restricts what you can carry — 65mm pitch will not take a filled 65mm deep gastronorm with a lid. If you carry deep pans, specify a wider pitch and accept fewer tiers.
Covered-side trolleys, which have panels on the back and sides, protect trays from splashes and knocks in transit and are worth the small premium in a busy corridor.
What castors and load rating do you actually need?
Castors are where cheap trolleys fail. The specification you want is 100mm to 125mm diameter wheels, at least two of them braked, with non-marking grey rubber or polyurethane tyres rather than hard plastic.
Wheel diameter matters because it determines what the trolley will roll over. A 75mm hard plastic castor stops dead at a 10mm door threshold or a drain channel and tips its load; a 125mm rubber castor rides over it. If your route between kitchen and function room crosses a car park, a service yard, or an aluminium threshold strip, specify the largest castor you can get.
Load rating should be read as a working figure, not a maximum. A trolley rated 150kg is comfortable at 100kg. A 15-tier rack holding 30 full gastronorm trays of prepared food can carry 60kg to 90kg of product before you count the trolley itself, and it will be pushed by a member of staff at speed around a corner.
Look for welded — not bolted — shelf-to-upright joints, a tubular frame rather than folded sheet, and a bottom shelf with a lip to stop items sliding off. Stainless steel 304 is standard and is what you want anywhere near food; painted mild steel chips and then rusts.
Folding or fixed frame — which suits your operation?
Choose a folding trolley if you store more trolleys than you use at once, or if you transport them. Event caterers, marquee operators, and venues with a single cramped store room benefit enormously: a folding 3-tier trolley collapses to a few centimetres thick and takes seconds to set up.
Choose a fixed frame if the trolley lives in one building and works hard every day. A welded fixed frame is stiffer, quieter, and has fewer moving parts to wear. Folding mechanisms are the most common failure point on a service trolley, and a trolley that has developed a wobble in its folding joint will not get better.
A reasonable compromise for a hotel or a caterer is a fixed trolley for daily front-of-house use and two or three folding trolleys held in reserve for functions.

What are the UK food safety rules for moving food on a trolley?
A trolley is transport, and moving food does not suspend temperature control. Hot food must be held at 63°C or above. Chilled food must be held at 8°C or below, and most operators work to 5°C. An open trolley provides no temperature control at all, so the clock starts the moment food leaves the holding equipment.
UK food hygiene rules allow hot food to be held below 63°C for a single period of up to two hours, after which it must be served, reheated to 63°C or above, or discarded. That two-hour window is a legal allowance, not a target — if a trolley journey from kitchen to function room routinely eats 20 minutes of it, use insulated containers or a heated trolley instead.
For chilled food there is a corresponding four-hour allowance above 8°C in limited circumstances, but the practical answer is the same: move cold food quickly, in covered containers, and return it to refrigeration.
Cross-contamination is the other risk. Never carry raw and ready-to-eat food on the same trolley without physical separation and covered containers, and dedicate a clearing trolley to dirty crockery rather than alternating it with a service trolley. Trolleys are food-contact equipment under UK hygiene law: they must be cleanable, cleaned, and included in your HACCP cleaning schedule, with castors and lower shelves cleaned as well as the top.
How do you choose the right trolley size?
Start with the narrowest doorway on the route, not the trolley catalogue. Measure the clear opening — the width between the door stops, not the frame — and subtract 50mm. That is your maximum trolley width. Lifts, corridors with radiators, and swing doors held open by a hook all bite here.
Then measure height against what you must pass under and what your staff can see over. A loaded 20-tier rack blocks the view of anyone under about 1.75m, which is a genuine safety issue in a busy kitchen corridor.
Finally, size on the peak job. A 60-cover restaurant clearing two services a day is served by a single 3-tier service trolley. A 120-cover hotel with function rooms needs two service trolleys plus a rack trolley for the kitchen. An event caterer plating 200 covers off-site needs folding trolleys in multiples, because they will always be moving in and out of a van in one trip.
Buy stainless, buy bigger castors than you think you need, and buy one more trolley than you think you need. Trolleys are the cheapest capacity you will ever add to a kitchen.
Frequently asked questions
How much does a catering trolley cost in the UK?
UK catering trolleys start at around £89 for a basic two-tier stainless service trolley and run to about £285 for a 15-tier gastronorm rack trolley. Folding three-tier trolleys sit around £159 to £168, and heavy duty three-tier service trolleys around £219 to £275. Castor quality and gauge of steel account for most of the price difference.
What size trays does a rack trolley take?
Most commercial rack trolleys take either GN 1/1 gastronorm trays at 530mm x 325mm or 600mm x 400mm bakery trays. The two are not interchangeable, so check the runner spacing against the trays your oven and blast chiller already use. Runner pitch is typically 60mm to 80mm, which limits how deep a loaded pan can be.
Can you keep food hot on a catering trolley?
Not on an unheated trolley. Hot food must be held at 63°C or above, and an open trolley loses heat quickly. UK rules allow a single period of up to two hours below 63°C, after which food must be served, reheated to 63°C, or discarded. For longer journeys use insulated transport boxes or a heated trolley, and probe on arrival.
Are folding catering trolleys strong enough for daily use?
Good folding trolleys handle daily front-of-house service, but a welded fixed frame is stiffer and lasts longer under heavy loads. Use folding trolleys where storage or transport matters — event catering, marquees, small stores — and fixed frames where a trolley works hard in one building every day. The folding joint is the usual wear point.
What castor size should a catering trolley have?
Specify 100mm to 125mm castors with non-marking rubber or polyurethane tyres and at least two brakes. Small hard plastic wheels catch on thresholds, drain channels, and lift edges, which is how loads get tipped. Larger wheels also roll more quietly and are far easier to push when the trolley is fully loaded.
How should catering trolleys be cleaned?
Treat trolleys as food-contact equipment. Wash and sanitise shelves after every service, clean the uprights and the underside of shelves daily, and include castors and the bottom shelf in the weekly deep clean — that is where debris collects. Stainless steel 304 tolerates commercial sanitiser well; keep the cleaning schedule in your HACCP records.
