Managing Subcontractors at Your Boatyard
Finding, vetting and coordinating marine subcontractors: insurance to check, agreements to sign, and how to keep the job on schedule.
10 min read By PayCamp Yards Team
No boatyard can do everything in-house. Specialist electronics installers, sailmakers, engine specialists, upholsterers, riggers—these skilled contractors extend your capabilities and allow you to offer a full-service experience. But subcontractors also introduce risk: to quality, scheduling, and your reputation. Managing them well is a core business skill for any UK boat yard operator.
When to Use Subcontractors
The decision to subcontract should be strategic, not reactive. Understanding when external expertise adds value—and when it introduces unnecessary complexity—helps you build a more resilient operation.
Good Reasons to Subcontract
- Specialist skills: Work requiring expertise you don't have in-house (e.g. marine electronics, GRP osmosis treatment)
- Capacity overflow: Peak periods when your team is stretched—particularly spring launch season
- Equipment needs: Work requiring specialist tools or facilities you don't own
- Certification requirements: Manufacturer-authorised work (e.g. engine warranties, electronics commissioning)
- One-off projects: Unusual work not worth developing internal capability for
- Geographic reach: Serving customers at locations beyond your primary yard
Conversely, avoid subcontracting core competencies that define your business. If antifouling is your bread and butter, outsourcing it dilutes your brand and margin. For guidance on pricing your core services, see our guide on how to price antifouling services.
Finding and Vetting Marine Subcontractors
The UK marine sector is relatively small—reputation travels fast. Finding reliable contractors requires a mix of industry networking and systematic due diligence.
Where to Find Contractors
- Referrals from other boatyards: Non-competing yards in different regions often share contractor contacts
- British Marine membership directory: Trade association members meet baseline standards
- Manufacturer recommendations: Engine, electronics, and paint manufacturers maintain approved installer networks
- Boat shows and trade events: Southampton, London, and regional shows are excellent networking opportunities
- Online marine forums: YBW, Sailing Forums, and specialist communities
Subcontractor Vetting Checklist
Documentation
- ✓ Public liability insurance certificate (minimum £2m)
- ✓ Employer's liability (if applicable)
- ✓ Professional indemnity (if applicable)
- ✓ Relevant certifications and qualifications
- ✓ COSHH assessments for hazardous materials
Due Diligence
- ✓ References from other marine businesses
- ✓ Examples of previous marine work
- ✓ Companies House registration check
- ✓ Health and safety policies and risk assessments
- ✓ Waste carrier licence (if removing waste)
Formal Agreements
Even with trusted long-term partners, written agreements protect both parties. A handshake might feel right for a small job, but when a £30,000 refit goes wrong, you need documentation.
Subcontractor Agreement Essentials
- Scope of work: Precisely what they will and won't do—ambiguity causes disputes
- Pricing: Fixed quote, day rate, or time-and-materials—plus process for variations
- Insurance requirements: Minimum cover levels and proof of current policies
- Liability: Who's responsible for what, including consequential damage
- Site rules: Working hours, safety requirements, environmental compliance, photography policy
- Payment terms: When and how they get paid—30 days is typical in the marine sector
- Quality standards: Expected finish, materials specification, warranty period
- Dispute resolution: Mediation before litigation saves relationships and money
Coordination and Communication
Poor coordination is the most common source of subcontractor problems. When multiple trades work on the same vessel, scheduling conflicts and miscommunication waste time and frustrate customers. Using scheduling software that includes external contractors prevents double-booking and keeps everyone informed.
Regular Subcontractors
- • May have independent site access with key/code
- • Know your systems and expectations
- • Can work with minimal supervision
- • Direct relationship with your team
- • Annual insurance and H&S review
Occasional Contractors
- • Require site induction each visit
- • May need supervision
- • Provide clear written briefing per visit
- • Check work before sign-off
- • Verify insurance is current before each engagement
Financial Management of Subcontractors
Pricing Models for Subcontracted Work
- Pass-through: Charge customers exactly what the subcontractor charges. Simplest but offers no margin on the work. Best for specialist one-off jobs where transparency matters.
- Markup (10-25%): Add a management fee to cover your coordination, quality control, and warranty backing. The industry standard for most subcontracted work.
- Inclusive pricing: Build subcontractor costs into your overall project quote. Customer sees one price. Better for complex refits with multiple trades.
Whichever model you use, ensure your invoicing system can track subcontractor costs against customer billing. This visibility is essential for maintaining healthy margins and understanding true job profitability.
IR35 and Tax Considerations
HMRC's IR35 rules apply to the marine sector. If a subcontractor works exclusively for you, uses your tools, and follows your schedule, HMRC may classify them as an employee—with significant tax implications for both parties.
- • Genuine subcontractors should work for multiple clients
- • They should provide their own tools and equipment
- • They should have control over how they complete the work
- • Keep records demonstrating genuine self-employment
Tools for Contractor Coordination
Building Long-Term Relationships
The best subcontractor relationships are partnerships, not transactions. When you find reliable specialists, investing in the relationship pays dividends through priority service, better pricing, and consistent quality.
- Consistent work: Regular jobs build commitment—give them first call on relevant work
- Fair treatment: Pay fairly and promptly; 30-day terms are standard but faster payment builds loyalty
- Open communication: Share feedback—both positive and constructive—regularly
- Mutual respect: Value their expertise and involve them in planning where appropriate
- Joint marketing: Recommend them to boat owners for work outside your scope; they'll reciprocate
- Seasonal planning: Share your annual schedule so they can plan capacity around your peak periods
