Our commercial gas subcontracting service supports facilities management companies, M&E contractors and PFI providers who need extra capacity for plant room services, interlock commissioning, CP17 tightness testing and reactive call-outs. We act as a labour-only or fully managed subcontracting partner.
Commercial gas scope we sub out
Our commercial gas subcontracting workload includes wall-hung modular boiler servicing, atmospheric and pressure-jet burner work, rooftop plant maintenance, gas booster sets, commercial water heaters, kitchen interlocks, CP17 tightness testing and CP42 catering gas safety records. Sites range from single-tenant offices to multi-storey hospitality estates.
Plant rooms
Modular boiler cascades, flue dilution fans, pressurisation units, expansion vessels and shunt pumps — full PPM and reactive cover.
Rooftop plant
Rooftop boilers and water heaters with safe access via mansafe systems, harness work and confined-space awareness where applicable.
Ticket sets we look for
Commercial gas applicants must hold current Gas Safe registration covering the fuel, appliance and work categories they undertake. Evidence commercial core and relevant appliance or pipework assessments for plant-room work, and the appropriate COMCAT categories for catering appliances. We check scope before offering each job.
Pricing and payment
Commercial tickets are priced per visit with hourly extension rates clearly stated. Parts are either van-stocked against an agreed list or purchased on our account. Payment terms and required worksheets and certificates are agreed before acceptance.
Insurance, RAMS and PPE
Subcontractors must hold £5,000,000 public liability for commercial work, valid CSCS or relevant skills card, current asbestos awareness, manual handling and working-at-height refresher training. Site-specific RAMS are produced by our team and issued before mobilisation.
Why subcontractors choose us for commercial gas subcontracting
We have built our commercial gas subcontracting pipeline specifically around the three things self-employed engineers tell us matter most — clear scopes, transparent pricing and agreed payment terms. When we have suitable work, each ticket reaches you with a fixed price, a clear scope of works, the customer's contact details and a parts plan so you can keep your tools moving instead of keeping a notepad.
Agreed payment terms
Payment terms are agreed with you before you start, and you never invoice our customers directly.
Payment records
Remittance details are provided for each payment so you can reconcile against your own records.
Tickets priced before issue
No haggling on the doorstep. Each commercial gas subcontracting ticket arrives in ServiceM8 with a fixed price, agreed parts list and customer access notes attached.
Accept or decline freely
You retain full control of your diary — decline anything that doesn't fit your travel radius, ticket set or van stock without any impact on future allocations.
Full back-office support
Customer triage, quoting, scheduling, parts ordering, certificate collection and complaint handling are all handled by our office. You focus on the engineering.
Coordinator on call
A named coordinator is available by phone for live site queries — variations, access issues and parts substitutions.
Commercial Gas Subcontracting FAQs
How quickly will I receive my first ticket?
Once your application, insurance and ticket evidence are verified, we offer commercial gas subcontracting tickets when suitable work is available in your area. We cannot guarantee when, or how much, work will be offered.
Onboarding window
Onboarding includes ServiceM8 setup, payment details capture and a short induction call covering scope of works, reporting standards and escalation routes.
Do I need my own van, tools and parts?
Yes — subcontractors are expected to operate with their own van and core toolkit. Major parts and the appliance itself are supplied from our merchant accounts at trade rates.
Van stock list
A recommended van stock list is shared at onboarding. Common consumables held in stock are reimbursed at trade price against the signed worksheet.
What insurance do I need to start?
A minimum of £2,000,000 public liability cover is required for domestic work, rising to £5,000,000 for commercial sites. Proof must be uploaded before any ticket is issued.
Annual renewal tracking
Our compliance system tracks every renewal date and prompts you 30 days in advance so cover never lapses mid-ticket.
Can I work across multiple regions?
Absolutely. You set your travel radius at onboarding and can adjust it at any time — we only push commercial gas subcontracting tickets that fall within the zone you choose.
Out-of-area uplift
Tickets accepted outside your standard radius receive a documented travel uplift agreed before mobilisation, so longer journeys are always priced fairly.
