Why subcontractors choose us for refrigeration engineer subcontractor job

No haggling on the doorstep. Each refrigeration engineer subcontractor job 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.
Refrigeration Engineer Subcontractor Job FAQs
How quickly will I receive my first ticket?
Once your application, insurance and ticket evidence are verified, we offer refrigeration engineer subcontractor job 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 refrigeration engineer subcontractor job 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.
