Our commercial plumber subcontractor panel covers washroom strip-outs, riser maintenance, calorifier swaps, booster pump fits and pressurisation unit faults for offices, retail, healthcare and hospitality clients across central London and the M25.
Commercial plumbing scope
Our commercial plumber subcontractor workload includes office washroom installs and strip-outs, riser pipework chases, calorifier and unvented cylinder swaps, booster pump sets, pressurisation units, water softeners and TMV servicing.
Washroom works
Strip-out and second fix on office, retail and hospitality washrooms, including IPS panels, vanity units and disabled-spec WCs.
Riser & plant
Vertical riser pipework, mains boosters, calorifier rooms and pressurisation set replacements.
Qualifications needed
We look for NVQ Level 3 Plumbing, G3 unvented hot water, WRAS water regs, current CSCS card, asbestos awareness, manual handling and working-at-height tickets. Brazing competence is required for any closed-system pipework on plant equipment.
Pricing and payment
Commercial plumbing tickets are priced per visit with day rates and parts handled through our merchant accounts. Larger refurb works are priced as fixed-price packages with stage payments tied to milestones.
Compliance, RAMS, PPE
£5,000,000 public liability is mandatory for commercial works. Site-specific RAMS are issued before mobilisation. PPE must meet site rules — typically Class 2 hi-vis, EN345 safety boots, eye protection and cut-resistant gloves as a baseline.
Why subcontractors choose us for commercial plumber subcontractor
We have built our commercial plumber subcontractor 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 plumber subcontractor 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 Plumber Subcontractor FAQs
How quickly will I receive my first ticket?
Once your application, insurance and ticket evidence are verified, we offer commercial plumber subcontractor 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 plumber subcontractor 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.
