A subcontract engineer on our books gets the same treatment whether they specialise in gas, plumbing, heating or air conditioning — consideration for suitable jobs with agreed scope and payment terms and a coordinator on the phone when things go sideways on site.
Trades we recruit
We recruit subcontract engineers across gas, plumbing, heating, air conditioning, refrigeration, mechanical, HVAC controls and BMS trades. Sole traders and small two-to-five-engineer teams are both welcome on the panel — we onboard based on tickets, insurance, traceable trade history and geographic coverage.
Sole traders
Sole traders are welcome to apply. Sole traders set their own travel radius and ticket mix.
Small teams
Two-to-five-engineer teams handle larger packages of work — multi-flat boiler installs, washroom refurbs and plant room services.
How the back office works
Our coordinators handle customer triage, quoting, scheduling, parts ordering, certificate collection and payment. Subcontractors get the parts of the job they enjoy — the actual hands-on engineering — without the parts they generally don't (chasing leads, raising invoices and waiting on payment).
Agreed payment terms and pricing
Payment terms and completion paperwork are agreed per job. Pricing schedules are published in advance and reviewed twice a year to keep pace with merchant cost movement. Any deductions, expenses and payment conditions must be agreed before a job is accepted.
Compliance and individual insurance
Every subcontractor we engage is checked against their trade register (Gas Safe, F-Gas, MCS, NICEIC) before tickets are issued. Insurance certificates and ticket renewal dates are tracked in our compliance system. Subcontractors remain responsible for their own workmanship, warranties and insurance.
Why subcontractors choose us for subcontract engineer
We have built our subcontract engineer 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 subcontract engineer 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.
Subcontract Engineer FAQs
How quickly will I receive my first ticket?
Once your application, insurance and ticket evidence are verified, we offer subcontract engineer 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 subcontract engineer 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.
