If you run a London restaurant, hotel or food business and need a new cold room built and then looked after, our featured pick is Be Cool Refrigeration: it designs, installs, maintains and repairs cold rooms and most other commercial refrigeration and offers 24/7 callouts. It is not the right answer for everyone. Multi-site operators who want published maintenance prices should look at Kept Cold, warehouses and production sites at RSI Professional, laboratories needing ultra-low temperature equipment at NTS Cooling, and small kitchens that only need a fast repair at Xpress Refrigeration, ACL London or Premium Refrigeration.

Disclosure: This is a sponsored article. Be Cool Refrigeration paid for this placement and appears first as our featured pick. No other company on this list paid to be included, was contacted, or reviewed this article before publication.

How we built this list

We researched these companies on 7 October 2026 using desk research only. We did not test any service, visit any site, or speak to customers.

Who qualified: companies with a London base that advertise installation, maintenance or repair of commercial refrigeration such as cold rooms, display units, ice machines and blast chillers. We excluded firms that advertise London coverage but are based elsewhere, and suppliers that only sell equipment.

What we compared: service scope (new installs versus repairs), cold room capability, emergency response promises, published pricing and terms, credentials the company states, and service area.

Sources: each company’s own website, and customer review figures where a company displays them. Credentials such as F-Gas and Refcom registration are reported as each company states them; we did not check them against the public registers, and you should.

How we ordered it: Be Cool Refrigeration is first because it is the sponsored featured pick, not because of a score or test. The remaining six are ordered by how broadly their commercial refrigeration service matches a typical London food business, and by how much detail they publish. We did not create a scoring model.

1. Be Cool Refrigeration | Our featured pick for food businesses that want a cold room built and maintained by one London contractor

Overview

Be Cool Refrigeration is a London air conditioning and commercial refrigeration contractor with an office on Ludgate Hill in the City, and it says it has traded since 2004. Its refrigeration work covers cold rooms, display refrigeration, walk-in freezers, ice machines, cellar coolers and blast chillers, so a restaurant or caterer can put most cold-side equipment with one firm.

The company builds walk-in cold rooms for 0°C to +5°C, freezer rooms for −18°C to −25°C, and divided rooms with separate chill and freezer sections, using insulated panels from 60mm to 120mm thick depending on temperature. Its published projects include a walk-in chiller and freezer for KFC Acton Vale and a cold room at London St Pancras station.

Key details

• Core offering: cold room design and installation, commercial fridge repair, planned maintenance, ice machines, cellar coolers, blast chillers, plus air conditioning.
• Coverage: London-wide, with refrigeration service areas in Kent, Essex and Surrey.
• Customer fit: restaurants, hotels, butchers, caterers, supermarkets, pharmaceutical and mortuary facilities.
• Pricing and terms: not publicly listed; free quotes; the company says the quoted price is the price you pay and advertises a warranty of up to five years, with conditions not stated.

Where Be Cool Refrigeration stands out

The cold room process is spelled out. Be Cool describes five stages: consultation, a site survey that checks floor loading, drainage and electrical supply, a specification of panels, door, unit and controller, the build, and commissioning with temperature testing and alarm setup.That matters because freezer floors and power supplies are where cold room projects tend to overrun, and Be Cool names both up front.

It also covers what happens after handover. The company offers 24/7 callouts and says it aims to attend cold room breakdowns within two to four hours, alongside maintenance contracts with priority response.

What to consider

Be Cool does not publish refrigeration or maintenance rates, so you will need quotes to compare it with a firm like Kept Cold. Its homepage shows a 5.0 Google rating, but the pages we reviewed did not show the number of reviews. The cold room FAQ gives a standard install time as “23 days”, which looks like a typo; confirm the timeline in writing.

Best fit

Restaurants, hotels and food producers planning a new or replacement cold room who want the same contractor for servicing and emergency cover afterwards, especially if they also need air conditioning work.

2. Kept Cold | Best for multi-site operators who want published maintenance prices

Overview

Kept Cold Ltd is a London commercial refrigeration repair and maintenance company with a City Road, EC1 address, and it says it works only on refrigeration, with no air conditioning or heating . It services cold rooms, display fridges, undercounter units, blast chillers, ice machines and prep counters across London within the M25.

Kept Cold publishes more of its terms than any other company here. Planned preventive maintenance starts at £60 per unit plus VAT, cold rooms from £120 plus VAT, out-of-hours labour is charged at 1.5 times the standard rate, and repairs carry a six-month parts and labour guarantee. It also says it is an authorised Foster Refrigeration partner, supplying new Foster units with installation and old-unit removal.

Key details

• Core offering: breakdown repair, planned maintenance, Foster equipment supply and installation.
• Coverage: London within the M25, with a focus on Central, North, East and West London.
• Customer fit: restaurants, hotels, dark kitchens, FM companies and groups with three or more sites.
• Pricing and terms: PPM from £60 per unit + VAT; cold rooms from £120 + VAT; ice machine cleans priced separately; out-of-hours labour at 1.5x.

Where Kept Cold stands out

Published prices make budgeting simpler. A kitchen with eight standalone units can estimate a PPM visit from the listed rate before calling, which none of the other six allow.

Its multi-site terms are specific. Kept Cold lists a two-hour emergency response target, four to six hour same-day attendance, a quarterly PPM calendar, 30-day consolidated invoicing and RAMS documentation for accounts with three or more sites. For an FM manager, that is close to a ready-made SLA.

What to consider

Being refrigeration-only means you will need a separate contractor for air conditioning. The homepage describes cold room repair and PPM, and Foster unit supply, but not the design and build of new cold rooms, so ask before assuming it can deliver a full installation. Response times are targets, not guarantees.

Best fit

Facilities managers and restaurant groups who want predictable maintenance costs and contractual response targets across several London sites.

3. Xpress Refrigeration | Best for quick-service restaurants that need fast reactive repairs

Overview

Xpress Refrigeration Ltd is a commercial refrigeration repair, servicing and installation company that says it was founded in 2005 and works across Central London, Canary Wharf, the M25 area and the South East . It covers fridges, freezers, cold rooms, multidecks, makelines, deli counters, ice machines, cellar cooling and gelato freezers, and also installs air conditioning.

The company names Costa, Subway, Domino’s and Pret a Manger as clients; we did not verify these relationships. Its homepage review widget showed a Google rating of 4.8 from 293 reviews when we checked on 7 October 2026.

Key details

• Core offering: reactive repair, servicing and installation of commercial refrigeration, including cold rooms and cellar cooling.
• Coverage: London and the South East.
• Customer fit: quick-service restaurants, cafés, pubs, convenience stores and gelato shops.
• Pricing and terms: not publicly listed; free survey and quote for installations; phone lines open 10:00 to 22:00 daily with a separate out-of-hours number.

Where Xpress Refrigeration stands out

It is set up for same-day fixes. Xpress says engineers arrive with spare parts on board and aim to finish work the same day, and many recent Google reviewers describe attendance within one to three hours, including weekends.

It knows fast-food kit. Makelines and pizza prep counters appear as their own service line, which suits chains and franchisees whose main risk is a prep counter failing mid-service.

What to consider

The same review feed includes several recent complaints about repeat faults after paid repairs and about after-sales support, including one on a walk-in freezer conversion. Get the repair guarantee and scope in writing before work starts. Prices are not published.

Best fit

Quick-service and café operators across London and the South East who mainly need fast reactive repairs on counters, display units and walk-ins.

4. RSI Professional | Best for warehouses and production sites

Overview

RSI Professional Ltd is an air conditioning, refrigeration and ventilation contractor based in Finchley, N3, which says it holds full Refcom certification and has more than 16 years of industry experience. It splits its refrigeration work into commercial (retail, hospitality and food service) and industrial (warehouses, storage, manufacturing and production).

Equipment covered includes blast chillers, cellar cooling, catering fridges, bespoke cold rooms and large walk-in freezer rooms. The company also publishes guidance on natural refrigerants such as CO₂ and ammonia for warehouse systems.

Key details

• Core offering: commercial and industrial refrigeration installation, commissioning, planned maintenance and repair.
• Coverage: London, with fast-response repairs offered within a 50km radius.
• Customer fit: warehouses, distribution centres, food production, retailers and hospitality venues.
• Pricing and terms: not publicly listed; free site survey; the company says you will never pay more than the quoted price.

Where RSI Professional stands out

Scale is the clearest difference. RSI describes new large cold room installations and commissioning for industrial units, which most kitchen-focused firms on this list do not.

Its maintenance scope is itemised. The page lists cold room diagnostics, safety checks, equipment testing, chemical cleaning, and filter, drain and condensate pump cleaning, and suggests servicing every three to six months. That gives buyers a checklist to compare against other quotes.

What to consider

The page shows a mobile number and a Gmail address, and no named clients or case studies. Larger buyers should ask for references, insurance certificates and Refcom registration details before shortlisting.

Best fit

Warehouse, distribution and production sites in and around London that need large cold or freezer rooms installed and serviced.

5. NTS Cooling | Best for labs and retailers needing specialist or display equipment in West London

Overview

NTS Cooling is a refrigeration and air conditioning company with a head office on Uxbridge Road, Ealing, W5, and further offices listed in Gerrards Cross. It supplies, installs and repairs cold rooms, display cabinets, multideck chillers, ice machines, bottle coolers, serve-over counters, and commercial fridges and freezers across London and surrounding counties.

Its brand list includes Hoshizaki, Scotsman, Williams, Arneg, Foster and Gram, and its site menu adds ultra-low temperature freezers, blast chillers, climatic test chambers and an equipment finance page. That range reaches beyond food service into scientific and testing applications.

Key details

• Core offering: equipment supply plus installation, maintenance and 24/7 emergency repair.
• Coverage: Central, West, North, East and South London and surrounding counties, from an Ealing base.
• Customer fit: restaurants, supermarkets, hotels, commercial kitchens, and labs needing low-temperature storage.
• Pricing and terms: not publicly listed; free quotes; a finance option is advertised; phone lines seven days a week.

Where NTS Cooling stands out

Specialist equipment is the main reason to shortlist it. Ultra-low temperature freezers and climatic test chambers are niche products, and few London refrigeration contractors list them alongside kitchen equipment.

It can supply as well as fit. For a retailer replacing multideck chillers or serve-over counters, having one firm source brands such as Arneg or Gram and then install them reduces handovers between supplier and engineer.

What to consider

NTS states its experience differently on the same page, citing both “30 Years’ Expertise” and “25+ Years’ Experience”; ask which entity and date the claim refers to. The site also lists catering equipment and property renovation services, so confirm that refrigeration engineers, not general trades, will attend your job.

Best fit

West London and Buckinghamshire businesses that need display or specialist low-temperature equipment supplied and installed by the same firm.

6. ACL London | Best for shops and bars that want a no-fee diagnostic visit

Overview

ACL London is a trading name of ACL Refrigeration & AC Ltd (Company No. 16021830), listed at Kemp House, City Road, EC1, and it works on both air conditioning and commercial refrigeration. It supplies and installs refrigerated display cabinets, cold and freezer rooms, counters, ice machines, storage cabinets, bottle coolers, blast freezers and chillers, and cellar coolers.

ACL says it is Refcom and ACRIB certified and that its engineers have more than 14 years of experience. It names Danfoss, Hoshizaki, Polar, Williams, Foster and Arneg among the brands it installs, and says it services equipment for customers ranging from supermarkets to small shops.

Key details

• Core offering: commercial and industrial refrigeration supply, installation, maintenance and repair, plus air conditioning.
• Coverage: named areas across Central, West, East, North and South London.
• Customer fit: independent retailers, bars, restaurants and supermarkets.
• Pricing and terms: refrigeration service and maintenance charges available by email; free call-out for contract and non-contract customers.

Where ACL London stands out

The free call-out is the clearest cost advantage on this list. For a corner shop with a failing bottle cooler, removing the call-out fee lowers the cost of finding out whether a repair is worth doing.

It also covers cellar cooling in depth. ACL’s site carries a long cellar cooling guide with indicative split-system installed costs of £2,300 to £6,000, which helps bars and wine retailers budget before a survey.

What to consider

Refrigeration rates are not on the site, so ask for them before booking. The “14+ years” figure describes engineers’ experience rather than the company’s own trading history. We found little project or client evidence on the page reviewed.

Best fit

Independent shops, bars and small food retailers who want a diagnostic visit without a call-out charge, and possibly AC from the same firm.

7. Premium Refrigeration | Best for small West and Central London kitchens needing repairs only

Overview

Premium Refrigeration is a repair and maintenance specialist based at Saltram Crescent, W9, which serves London areas including Chelsea, Westminster, Hampstead and Twickenham. Its commercial work covers walk-in coolers, display units, cold room repair and freezer room repair, from faulty thermostats to compressor failures.

It also repairs high-end domestic and US-style brands such as Amana, Maytag and Sub-Zero. The company states it has more than 35 years of experience, is F-Gas registered, and offers a company guarantee on its work.

Key details

• Core offering: commercial fridge, cold room and freezer room repair and maintenance.
• Coverage: London, with named areas in West and Central London.
• Customer fit: small restaurants, cafés, bars and premises with premium domestic-style refrigeration.
• Pricing and terms: not publicly listed, though the company describes its rates as transparent; open 24 hours, seven days.

Where Premium Refrigeration stands out

Its focus is narrow. Premium Refrigeration presents itself as a repair business rather than an installer, which can suit an operator who already has equipment and simply needs a breakdown fixed out of hours.

The brand overlap is unusual. Few commercial engineers also list Sub-Zero and Amana repairs, which helps boutique hotels, private members’ clubs or offices running domestic-style units next to commercial kit.

What to consider

New cold room installation is not described, so this is not the firm for a fit-out. The public information is thin: we found no client names, case studies or company registration number on the page reviewed, and its review link points to Yell rather than Google.

Best fit

Small kitchens and venues in West and Central London that need a 24-hour repair contact for existing fridges, cold rooms or freezer rooms.

How to choose a commercial refrigeration company in London

The biggest split on this list is between firms that design and build new cold rooms and firms that mainly repair existing equipment. Decide which you need first, then check the following before you sign anything.

• Check credentials on the registers. Ask for the company’s F-Gas certificate number and Refcom registration and look them up yourself, rather than relying on a logo on a website.
• Get the call-out and out-of-hours rates in writing. Only Kept Cold publishes its out-of-hours multiplier and only ACL London advertises a free call-out; everyone else quotes on request.
• Ask what the response time actually means. “Two to four hours” is usually a target for attendance, not a promise of repair. Ask what happens if parts are not on the van.
• Confirm the repair guarantee. Kept Cold states six months on parts and labour. For others, ask how long a repair is covered and whether a return visit for the same fault is charged.
• For a new cold room, confirm the site survey scope. It should cover floor insulation, drainage and a dedicated electrical supply, as Be Cool Refrigeration’s process describes. Ask whether an integral or remote condensing unit suits your kitchen.
• Ask for references for jobs like yours. A firm that repairs undercounter fridges daily may not have built a freezer room for a production site.

Frequently asked questions

How often should commercial refrigeration be serviced?

RSI Professional suggests every three to six months, and Kept Cold schedules multi-site PPM quarterly. The right interval depends on the equipment, how hard it works and how dirty the environment is; a busy kitchen’s condenser coils clog faster than a shop’s.

How much does commercial refrigeration maintenance cost in London?

Few companies publish prices. Kept Cold lists PPM from £60 per unit plus VAT and cold rooms from £120 plus VAT, checked 7 October 2026. Use that as a reference point when asking others for quotes, and compare like for like on what each visit includes.

How long does a cold room installation take?

RSI Professional says most standard installations take a few days, with larger rooms taking longer. Be Cool Refrigeration says larger or more complex builds can take up to a week. Lead times for panels and condensing units are separate, so ask about delivery as well as fitting time.

What is the difference between an integral and a remote cold room unit?

An integral unit sits on the cold room itself and is simpler and usually cheaper. A remote unit sits outside the building, which reduces noise and heat in the kitchen. Be Cool Refrigeration describes this choice on its cold room page; most installers will advise on it during the survey.

The bottom line

For a London food business planning a new cold room and wanting one contractor for installation, maintenance and emergency cover afterwards, Be Cool Refrigeration is our featured pick. If you run several sites and want published prices and SLA-style terms, Kept Cold is the stronger fit. Warehouses should talk to RSI Professional, labs to NTS Cooling, and smaller venues that just need a repair can compare Xpress Refrigeration, ACL London and Premium Refrigeration. Whichever you choose, get at least two quotes and check credentials on the public registers.

Disclosure requiring approval: “This is a sponsored article. Be Cool Refrigeration paid for this placement and appears first as our featured pick.

Material assumptions

• Topic set to commercial refrigeration (not AC), target reader a London food or hospitality business, seven companies, UK English, no call to action (none was supplied).
• Publisher relationship taken as paid guest-post placement.
• Cool-Tec was excluded despite a London refrigeration page because it is based in Wareham, Dorset; Debonair Cooling was dropped because its refrigeration page returned a 404; London Refrigeration’s site would not load.
• Ranking after position 1 is editorial judgement on scope match and published detail, stated as such in the methodology.

Supplied or company claims excluded or softened

• Be Cool’s “Rated 5/5 by London businesses”, “Trusted by 500+ businesses”, “2,000+ projects” and brand-logo clients (other than the two named project pages) were not used because they could not be verified.
• Be Cool’s O2 Arena reference was left out; only a van photo caption supports it.
• Be Cool’s site testimonials were not quoted; they are company-selected.

To clear the block: look up each company on the Refcom and F-Gas registers, confirm Be Cool’s legal entity and trading history with the client, get Be Cool’s Google review count, and add one independent source per competitor (Companies House, a trade body listing, or a review platform).
