Define the refrigeration contract before comparing quotes
A useful refrigeration specification starts with what the business needs to keep cold, not simply the available floor space. State the product type, incoming product temperature, required storage temperature, loading pattern and expected door openings. A walk-in room holding already chilled ingredients has a different duty from equipment expected to cool warm deliveries. Include the kitchen or stockroom ambient temperature: equipment selected for a moderate environment may struggle beside cooking appliances or in a poorly ventilated basement.
Ask for a written boundary between refrigeration work and associated building services. This should identify responsibility for electrical supplies and isolators, condensate drainage, builders’ openings, fire stopping, lifting arrangements and making good. Specify whether shelving, temperature monitoring and removal of redundant equipment belong in the contract. Air Conditioning Installation London provides a fixed written quote before work starts. Use that stage to resolve inclusions, exclusions and assumptions rather than leaving them to be interpreted once work is under way.
Coordinate refrigeration with the London premises
London sites often make access and heat rejection as important as equipment capacity. A basement restaurant may have a narrow stairway and limited condenser airflow; an upper-floor hotel kitchen may need a managed delivery route. In a mixed-use building, an external condensing unit can raise questions about noise, vibration and proximity to residential windows. Establish proposed equipment positions and access routes early, including how components could eventually be removed without dismantling unrelated parts of the premises.
The refrigeration contract should identify interfaces with the landlord, managing agent, electrician and fit-out team. Confirm any required permissions for roof access, external equipment and penetrations through walls or floors. Refrigerant pipe routes need practical support and insulation, while condensate drains need a suitable route and provision against blockage or freezing where relevant. Do not assume that a nearby socket, drain or roof space is suitable just because it exists; compatibility and permission are separate checks.
Specify performance rather than equipment size alone
Compare proposals against a defined cooling duty and operating conditions. Compressor capacity, evaporator selection, condenser heat rejection and expansion-device sizing must work together; a larger compressor is not a substitute for a correctly matched system. For cold rooms, insulation thickness, door seals, floor construction and defrost arrangements also affect performance. Ask what ambient and room temperatures underpin the selection, and whether the quoted duty accounts for lighting, people, product loading and frequent access during busy service periods.
Food safety requirements should inform the specification without confusing air temperature with product temperature. In England, food that requires chilled temperature control generally needs to be kept at 8°C or below, subject to applicable exceptions; setting refrigeration at 5°C or below provides useful operating margin. Frozen storage commonly targets −18°C or colder, depending on the product specification. Agree how temperatures will be monitored and recorded within your food safety procedures, and whether alarms or independent probes need to be included.
Allocate refrigerant and F-Gas responsibilities clearly
Air Conditioning Installation London is REFCOM F-Gas registered. Where equipment contains fluorinated refrigerant, the contract should identify the refrigerant, charge quantity and responsibilities under the applicable GB F-Gas rules. Leak-check obligations depend on factors including the refrigerant’s CO₂-equivalent charge and whether qualifying hermetically sealed equipment exemptions apply. The equipment operator retains legal responsibilities even when a contractor undertakes the work, so establish who maintains records, tracks required checks and receives reports of refrigerant added or recovered.
Refrigerant choice also affects future access to servicing materials and the precautions needed on site. High-GWP refrigerants such as R404A are subject to servicing restrictions; any proposal involving existing equipment should consider the current rules and permitted refrigerant sources. R290 is a hydrocarbon refrigerant rather than an F-gas, but its flammability requires suitable equipment design and working practices. Neither a refrigerant change nor a different charge should be treated as an interchangeable option without checking the equipment’s design and manufacturer requirements.
Agree a work sequence that protects trading and stock
For an occupied restaurant, supermarket or catering kitchen, the contract programme needs to distinguish site access from equipment availability. Agree which areas must be cleared, when supplies may need isolation and who authorises interruptions. Identify where chilled or frozen stock will be held if existing equipment is unavailable; do not assume temporary storage is included. Delivery slots, loading restrictions, goods-lift bookings and access through shared areas can all determine the workable sequence at a London business premises.
Set out how changes will be handled if site conditions differ from the agreed assumptions. Examples include an inadequate electrical supply, concealed pipework, an unsuitable drain connection or insufficient ventilation around a proposed condenser position. Any change to scope, price or timing should be agreed in writing before the additional work proceeds. Keep one named decision-maker available from your business, particularly where several trades are involved, so practical questions do not become delays or unapproved substitutions.
Set handover requirements and request your written quote
Define completion in terms of evidence, not merely whether the equipment switches on. Depending on the contracted work, the handover requirements may include equipment identification, refrigerant and charge details, electrical information, operating instructions and relevant test records. For new pipework, pressure-test, evacuation and leak-check records provide important evidence of work completed. Agree the operating conditions for demonstrating temperature performance: an empty room reaching its setpoint does not establish how it will cope with warm stock and repeated door openings.

Frequently asked questions
What should a commercial refrigeration contractor’s quote include?
Look for a defined scope, equipment specification, design conditions, refrigerant details and clear exclusions. The quote should identify who provides power, drainage, access equipment and associated building works, together with the agreed handover requirements. Check whether removal of old equipment and any stock-storage arrangements are included rather than assumed. Air Conditioning Installation London provides a fixed written quote before work starts, giving you an opportunity to clarify these boundaries.
Can I use a refrigeration contractor alongside my shopfitting team?
A refrigeration contract can sit alongside a wider fit-out, but responsibilities need to be mapped before work begins. Give each trade the relevant equipment positions, electrical requirements, drainage routes and access constraints. Agree who coordinates penetrations, fire stopping and finishes, and when refrigeration areas will be ready. When discussing your project, explain whether a principal contractor, landlord or managing agent controls access, approvals and the overall programme.
Is F-Gas registration relevant to every refrigeration system?
F-Gas certification requirements apply to specified work involving fluorinated refrigerants; they do not apply in the same way to every refrigerant. For example, R290 is propane and brings flammability considerations rather than F-Gas controls. Ask for the refrigerant designation and the competence appropriate to the proposed equipment and work. Air Conditioning Installation London is REFCOM F-Gas registered. The contract should also clarify any applicable operator records and leak-check responsibilities.
What information should I prepare before requesting a quote?
Provide the premises address, the products being stored, required temperatures and typical loading patterns. For existing equipment, include data-plate photographs showing the model and refrigerant where legible. Explain access restrictions, trading hours, proposed equipment positions and any known electrical or drainage limitations. If the project involves an installation, a free site survey is available. Early information helps establish a realistic scope rather than relying on assumptions about the building or cooling demand.
