AAC Gas provide specialist commercial kitchen gas and LPG services across Merseyside and the surrounding areas. Gas Safe registered and working exclusively with commercial clients, our engineers service, repair, and certify gas installations in restaurants, hotels, pubs, takeaways, care homes, hospitals, schools, and workplace canteens across all five Merseyside boroughs — Liverpool, Knowsley, St Helens, Sefton, and Wirral.
Liverpool is one of the UK's most vibrant and competitive hospitality cities — from the independent restaurants and bars of the Baltic Triangle and Bold Street to the hotel kitchens along the waterfront and the large-scale catering operations at hospitals, universities, and care homes across the wider Merseyside region. Every commercial kitchen across that sector has a legal obligation to maintain valid CP42 gas safety certification and keep its gas systems in safe, compliant working order throughout the year.
Call us on 01772 382971 — available 24/7 for commercial kitchen gas emergencies across Merseyside.

The CP42 is the annually required gas safety certificate for every commercial kitchen. It covers all gas appliances — ranges, ovens, fryers, grills, salamanders, pasta cookers, bratt pans, combi ovens, and all other gas-fired catering equipment — together with the gas interlock system, ventilation, and gas pipework throughout the kitchen.CP42 certification is a legal requirement for any business operating a commercial kitchen across Merseyside. It is routinely checked by Environmental Health Officers during food business inspections, required by insurers, and forms part of the compliance documentation reviewed by hotel chains, care home operators, hospital trusts, and institutional catering managers.Our Gas Safe engineers carry out CP42 inspections across Merseyside with minimum disruption — scheduling outside service hours wherever possible. Certificates are issued on the day of inspection, clearly documented and ready for audit.
A gas interlock system automatically cuts the gas supply to kitchen appliances if the ventilation system fails or is not running. Gas interlock systems are a legal requirement under current Building Regulations and gas safety standards for commercial kitchens across Merseyside.We test, commission, and certify gas interlock systems throughout Merseyside — verifying the proving sequence operates correctly, confirming all interlocked appliances respond to a ventilation failure, and issuing the required certification. We also repair and replace faulty interlock systems and advise on upgrades where older systems no longer meet current standards.
Regular servicing of commercial catering appliances reduces the risk of breakdown during busy service periods, extends equipment life, and maintains safe, efficient operation. Our engineers service all types of gas-fired catering equipment across Merseyside including:
We work across all major catering equipment brands including Rational, Falcon, Blue Seal, Hobart, Electrolux Professional, Lincat, MKN, Henny Penny, Manitowoc, and all other commercial catering manufacturers.
When a gas appliance fails mid-service in a Liverpool restaurant, a Wirral hotel kitchen, or a St Helens care home, every minute matters. Our engineers provide fast-response commercial kitchen gas repairs across Merseyside — diagnosing faults on all types of gas catering equipment and carrying out efficient repairs to restore your kitchen to full operation as quickly as possible. We carry commonly required parts and aim to complete repairs on the first visit wherever possible.
We carry out gas pipework installation, alteration, and testing for commercial kitchens across Merseyside — including new appliance connections, kitchen reconfigurations, pipework alterations during kitchen refurbishments and refits, and full gas tightness testing. All pipework work is carried out to current Gas Safe standards and fully documented on completion.
Not all commercial kitchens across Merseyside are connected to the mains gas network. Some venues — particularly in older Liverpool city centre buildings, Wirral coastal locations, and rural areas on the fringes of Merseyside — operate on LPG. Our engineers are fully qualified to service, repair, and certify LPG gas installations in commercial kitchens across Merseyside, including bulk LPG supply systems, cylinder manifold installations, LPG pipework, and all LPG-fired catering appliances.We carry out CP42 certification for LPG commercial kitchens and advise on system upgrades, safety improvements, and conversions where required.
All new gas catering equipment installed in a Merseyside commercial kitchen must be connected and commissioned by a Gas Safe registered engineer. Our team handles new appliance gas connections and commissioning across Merseyside — ensuring correct gas pressure, safe operation, and issuing the required Gas Safe documentation. We work alongside kitchen fit-out contractors and equipment suppliers to ensure installations are completed safely and on schedule.
A gas fault in a commercial kitchen forces an immediate shutdown — costing restaurants, hotels, and care home kitchens significant revenue and disruption with every hour offline. Our engineers are available 24 hours a day, 7 days a week for emergency commercial kitchen gas call-outs across all areas of Merseyside. Call 01772 382971 at any time and we will respond as fast as possible.
