DDWilson is commercial gas-safe, and our engineers can carry out commercial gas work for your business, warehouse, school or care home. Being commercially gas-safe enables us to work on significant gas installations or commercial environments.
Our commercial gas specialist, Stephen Boardman, holds full Non-Domestic Gas Safe certification.
Domestic gas engineers are not legally permitted to carry out or complete commercial gas boiler services, installations, or maintenance. You must contact a certified company, such as ddwilson.com. We recommend that business proprietors contact a certified commercial gas-safe company for their commercial gas requirements.
Our commercial gas engineers are available to visit your premises for emergencies, and we endeavour to identify and fix the issue as soon as possible. You can trust us to get your business back up and running as quickly as possible.
What Our Commercial Clients Say
Activate Specialist College, Kirkby
Jane Young, CEO & Principal
"We're a college based in Kirkby providing education to young people aged 19-25 with varying degrees of special educational needs, including autism, Down syndrome, and complex health needs. We really like to use local companies. We are quite a community-based college. We used DD Wilson originally as they were local, but also because they gave us a really competitive quote. They came out really quickly. That's really important for us because if we have any issues on site, we need to fix them quickly. We very rarely close, and having them able to come and sort out an issue really quickly helps us. Communication's really good from DD Wilson. It's great that we have a designated contact, so we always know we can pick up the phone and speak to that person. I would highly recommend them to any other organisations, mainly due to their reliability, their expertise, and their efficiency, because they're always here when they say they're going to be."
What Is A CP17 Certificate
Commercial Gas Safety Certificates (CP17) in Liverpool, Wirral & Merseyside
DD Wilson Gas & Heating Engineers provides comprehensive CP17 commercial gas safety inspections for businesses across Liverpool, Wirral and Merseyside. Our Gas Safe registered engineers ensure your commercial premises meet all legal requirements under UK gas safety regulations.
CP17 Commercial Gas Safety Inspections
A CP17 is a Commercial Gas Installation Safety Report for non-domestic premises. This certificate verifies the safe operation of commercial gas installations, including heating systems, boilers, warm-air heaters, and radiant heaters, in buildings such as hotels, offices, schools, warehouses, and care homes. Our Gas Safe-registered engineers carry out comprehensive annual inspections to ensure your commercial gas equipment is safely installed and operating correctly. Under the Gas Safety (Installation and Use) Regulations 1998, business owners and duty holders are legally responsible for ensuring that all gas systems are maintained in a safe condition.
What We Inspect During a CP17 Assessment
Our comprehensive CP17 inspection follows the standards set out in BS6173 (gas installation specification) and IGEM/UP/19 (commercial catering procedures). The inspection covers all aspects of your commercial gas installation:
-
Gas appliance safety: Condition, operation and safe functionality of all commercial gas equipment, including boilers, ovens, fryers, grills, hobs and heating systems
-
Pipework integrity: Complete gas soundness testing of all pipework to detect any leaks or deterioration
-
Safety devices: Testing of gas valves, flame failure devices, thermostats and automatic shut-off systems
-
Interlock systems: Verification that the gas supply correctly interlocks with the ventilation and extraction systems
-
Ventilation assessment: Performance testing of extraction systems to DW172 specifications
-
Air quality monitoring: CO and CO2 level checks to ensure safe working environments
-
Emergency controls: Testing of emergency gas shut-off valves and their accessibility
-
Hose and connector inspection: Condition, alignment and suitability of flexible connections
Upon successful completion, we issue your CP17 Commercial Gas Safety Certificate, valid for 12 months from the date of inspection.
Why Commercial Gas Safety Matters
Gas safety in commercial premises is not simply a compliance exercise. Poorly maintained gas equipment poses serious risks to staff, customers and your business.
Carbon Monoxide: The Silent Threat
Carbon monoxide (CO) is a colourless, odourless gas that causes approximately 60 deaths per year across England and Wales, with around 4,000 people treated in A&E departments annually for CO poisoning (Department of Health and Social Care figures). Central heating boilers account for 26% of all CO-related deaths in the UK, while commercial premises account for 4% of recorded incidents (CO-Gas Safety data 1995-2023).
Commercial kitchens operating multiple high-demand gas appliances for extended periods face elevated risks. Without proper ventilation and regular safety inspections, carbon monoxide can accumulate to dangerous levels, causing symptoms ranging from headaches and nausea to loss of consciousness and death.
A Liverpool John Moores University study found that fewer than 10% of properties have carbon monoxide alarms fitted, highlighting the importance of professional gas safety inspections to identify hazards before they cause harm.
Legal and Financial Consequences
Operating without a valid CP17 certificate exposes your business to serious legal and financial risks:
-
Criminal prosecution: Regulation 35 of the Gas Safety (Installation and Use) Regulations allows for fines up to £6,000 and imprisonment for up to six months
-
Insurance invalidation: Most commercial insurance policies require current gas safety certification; claims may be rejected if you cannot produce a valid CP17
-
Manslaughter charges: In cases where gas safety failures result in death, responsible persons can face corporate manslaughter charges
-
Business closure: Local authorities and the Health and Safety Executive can order the immediate closure of premises with unsafe gas installations.
