Whether you are fitting out a restaurant, opening a convenience shop or adding chilled storage to a catering workspace, the installation needs planning around access, electrical supplies, drainage and ventilation. We cover all 32 London boroughs, the City of London and M25 towns. Call 07427 826446 between 07:00 and 21:00, seven days a week, to discuss your premises, intended stock and installation requirements.
Specify Refrigeration Around Your Stock and Daily Workload
Start with what you need to store, its required temperature and how it moves through the premises. A restaurant prep counter, a deli display cabinet and a walk-in freezer have different duties. Capacity should account for peak stock levels without packing products against evaporator air outlets. Door-opening frequency, kitchen ambient temperature and the temperature of incoming goods all affect cooling load. Storage refrigeration should not be treated as a substitute for a blast chiller when cooling freshly cooked food.
For most foods that require chilled temperature control in England, the legal maximum is 8°C, subject to applicable exceptions; a fridge setting of 5°C or below helps provide an operating margin. The correct target still depends on the product, its labelling and your food safety procedures. Frozen-food storage commonly targets −18°C or colder. Share these requirements during the survey, together with delivery schedules and expected growth, so equipment selection reflects actual use rather than floor space alone.
Plan the Installation Around Your London Premises
London sites often have constraints that are easy to miss when ordering equipment online: narrow basement stairs, shared loading areas, restricted delivery times and limited space behind counters. Measure the complete delivery route, including door openings, corners and any lift dimensions or load limits. For a modular cold room, allow for panel assembly, door swing and usable internal height. For cabinets, check that handles, hinges and ventilation clearances fit the intended position, not just the published external dimensions.
The free installation site survey is the opportunity to identify these restrictions before agreeing the work. In a trading café or restaurant, discuss when deliveries can arrive and which preparation areas must remain accessible. Upper-floor offices, basement kitchens and shops beneath flats may also need particular attention to noise, access and external equipment locations. Landlord consent, building management approval or planning permission may be needed depending on the proposed alterations; establish responsibility for those approvals before installation begins.
Choose Equipment With Suitable Ventilation and Heat Rejection
An integral refrigerated cabinet contains its own compressor and condenser, so it releases heat into the room where it stands. Several cabinets in a compact kitchen can significantly increase the room temperature. Their condenser grilles need the manufacturer’s specified clearances and must not discharge into an enclosed cupboard. Poor airflow can lead to high condensing pressure, excessive energy use and compressor trips. Installation planning should therefore consider the kitchen’s ventilation and heat load alongside the refrigeration unit itself.
Equipment with a separate condensing unit moves heat rejection away from the refrigerated space, but introduces refrigerant pipework and another location to assess. Pipe length, vertical lift and permitted routing must suit the selected equipment. An outdoor position needs appropriate airflow, service access and consideration of noise near neighbouring windows. Avoid assuming that a lightwell or small yard will work: warm discharge air can recirculate in confined spaces. The practical choice depends on the premises, not simply the equipment’s purchase price.
Prepare Electrical Supplies, Drainage and Refrigerant Connections
Check the equipment’s electrical requirements before delivery. Some cabinets use a suitable socket supply, while other equipment requires a dedicated circuit or three-phase power. Starting current, protective devices and local isolation must be considered against the manufacturer’s instructions and the existing installation. Any necessary electrical alterations should be identified in the written scope rather than assumed to be included. Extension leads and overloaded adaptors are not an appropriate way to resolve an unsuitable supply for permanent commercial refrigeration.
Condensate arrangements also vary: a cabinet may have an evaporation tray, while other equipment needs a properly routed drain. Drain falls, suitable connections and protection against freezing matter, particularly for freezer evaporators. Where refrigeration connections are made on site, pipe sizing, insulation, support and joint quality affect reliability. Dry nitrogen during brazing helps prevent internal oxidation, and appropriate pressure testing and evacuation are essential before charging. These requirements differ from positioning a factory-sealed cabinet, whose refrigerant circuit normally remains unopened.
Account for Refrigerant Safety and F-Gas Requirements
Refrigerant choice affects installation requirements as well as environmental impact. Many self-contained commercial cabinets use R290, or propane, which is highly flammable and requires the location, charge limits and potential ignition sources to be considered under the applicable standards and manufacturer’s instructions. R744, or carbon dioxide, operates at much higher pressures and needs equipment designed for that duty. Neither refrigerant is an F-gas, but that does not remove the need for appropriate competence and safe installation practices.
For equipment containing fluorinated refrigerants, the applicable GB F-Gas rules govern matters including qualified handling, leak prevention and restrictions on certain new equipment. Requirements depend on refrigerant type, charge and application, so a refrigerant should not be selected solely because it was used in an older unit. Air Conditioning Installation London is REFCOM F-Gas registered. Before accepting a specification, establish which refrigerant is proposed and what operator obligations apply, including any required records or periodic leak checks for that particular system.
Agree the Installation Scope and Prepare for Stock Loading
A useful installation quote makes the boundaries clear: equipment specification, positioning, any on-site refrigeration connections and the enabling work needed at the premises. Discuss access arrangements, electrical preparation, drainage, wall penetrations and making good so there are no assumptions about who provides what. Air Conditioning Installation London offers a fixed written quote before work starts. Bring floor plans, equipment details if already selected, and photographs of the proposed location to the discussion; these help establish what needs checking during the free site survey.
Do not plan to load perishable stock immediately after equipment is moved into position. Follow any manufacturer’s settling instructions, then allow the empty unit to pull down and stabilise at its intended operating temperature. Confirm door closure, unobstructed airflow and the controller settings before use, and verify food temperatures through your own food safety procedures rather than relying only on the display. To arrange your installation survey anywhere across our London and M25 coverage area, call 07427 826446, seven days a week, 07:00–21:00.

Frequently asked questions
What information should I provide when requesting an installation quote?
Tell us your business type, site address, what you intend to refrigerate and the required storage temperature. Include approximate stock quantities, available dimensions and any equipment model you have already selected. Photographs of the location, delivery route and nearby electrical supplies are useful. Mention stairs, restricted loading times and landlord requirements. A free installation site survey can then establish the practical requirements before a fixed written quote is issued.
Can refrigeration be installed while my business remains open?
That depends on the equipment, access route and work needed. Positioning a self-contained cabinet presents different disruption from assembling a cold room or running pipework through preparation areas. Agree delivery access, separation from food handling and any electrical shutdowns before setting the installation date. Existing stock must remain under suitable temperature control throughout. Discuss your trading hours during the survey so the proposed sequence can be assessed against your business operations.
Does a commercial fridge need an outdoor unit?
Not necessarily. An integral cabinet has its compressor and condenser built in and normally rejects heat into the surrounding room. It needs adequate ventilation and the specified clearances. A remotely connected cabinet or cold room uses a separate condensing unit, whose location must be assessed for airflow, noise and pipework limits. Neither arrangement suits every premises; available space, room temperature and equipment duty should guide the installation specification.
How long does commercial refrigeration installation take?
There is no reliable single timescale without knowing the equipment and site conditions. Delivery access, panel assembly, electrical preparation, drainage and any refrigerant pipework all affect the programme. Approvals or enabling work can also determine when installation can begin. Allow additional time for temperature stabilisation before stocking. The site survey should establish the work sequence and identify dependencies, rather than treating delivery day as a guaranteed ready-to-use date.
