The ultimate 2026 UK contractor compliance checklist

Supply chain compliance. It’s rarely the reason anyone starts a contracting business, but it’s the exact reason many businesses survive and thrive. Keeping up with regulations isn’t just about ticking boxes; it’s about keeping your people safe, protecting your reputation, and ensuring you get paid without hassle.

As 2026 begins, the landscape for UK contractors is shifting yet again. Staying ahead of these changes can feel like a full-time job in itself. That’s why we’ve put together this straightforward checklist. Our goal is simple: to help you navigate the complexity so you can focus on the work you do best.

Here is your essential guide to contractor compliance for the year ahead.

1. Health and safety: The foundation of compliance

Health and safety remains the cornerstone of any compliant contracting business. This year we’re expecting the Health and Safety Executive (HSE) to continue to tighten its focus on specific areas, particularly mental health and digital safety records.

Update your risk assessments

Are your risk assessments gathering dust? They shouldn’t be.

• Review annually: Ensure every assessment covers current working practices.
• Include mental health: Stress and mental well-being are now critical components of workplace safety. Make sure your assessments account for psychosocial risks.
• Digitise your records: Paper trails are becoming obsolete. Moving your safety data to a digital format ensures it is accessible and audit-ready at a moment’s notice.

Check your training records

An untrained workforce is a non-compliant one.

• Refresh certifications: Check expiration dates on CSCS cards, asbestos awareness, and first aid certificates.
• Upskill for new tech: If you plan on using new machinery or software in 2026, ensure your team has the documented training to prove they can use it safely.

2. Insurance: Protection for the unexpected

Having the right insurance isn’t just a legal requirement; it’s a sign of a professional business. Clients in 2026 are more risk-averse than ever and will expect comprehensive coverage before you step foot on site.

Verify your coverage levels

Standard coverage might not cut it for larger contracts.

• Public liability: Most major clients now demand a minimum of £5 million cover, with some pushing for £10 million. Check your policy limits.
• Professional indemnity: If you offer advice or design services, this is non-negotiable.
• Employers’ liability: If you have even one employee, you legally need at least £5 million cover.

Review policy exclusions

The fine print matters. Ensure your policy actually covers the specific activities you undertake. If you’ve diversified your services recently, tell your broker. You don’t want to find out you aren’t covered after an incident occurs.

3. Financial and tax obligations: Staying on the right side of HMRC

The financial side of compliance is often where contractors feel the most pressure. With IR35 rules now firmly embedded, 2026 requires strict adherence to tax laws.

CIS returns and VAT

• Construction Industry Scheme (CIS): Ensure your gross payment status is secure by filing monthly returns on time, every time.
• VAT reverse charge: Double-check you are applying the reverse charge correctly on construction services. Mistakes here can lead to significant cash flow issues and penalties.

4. Environmental and sustainability standards

Sustainability is no longer a “nice-to-have” addition to a tender document. In 2026, it is a core compliance metric. Clients, especially in the public sector, have strict carbon reduction targets that trickle down to their supply chain, which means you.

Track your carbon footprint

You don’t need to be a climate scientist, but you do need awareness.

• Vehicle emissions: Are you upgrading to electric or hybrid vans?
• Waste management: Do you have waste transfer notes for every job? Are you recycling materials where possible?
• Material sourcing: Can you prove your materials come from sustainable sources?

Demonstrate social value

Big contracts often ask what you give back to the community.

• Local labour: Do you hire locally?
• Apprenticeships: Are you training the next generation?
• Community engagement: Do you support local charities or initiatives?

5. Data protection and cyber security

Contractors hold sensitive data, from employee records to client blueprints. GDPR is still very much in force, and cyber threats are rising.

• Secure your devices: Ensure laptops and phones are encrypted.
• Update privacy policies: Make sure your data handling policies are transparent and up to date.
• Staff awareness: Train your team to spot phishing emails. A single click can compromise your entire business.

6. Supply chain visibility

Clients want to know exactly who is working on their sites. If you subcontract work, you are responsible for their compliance too.

• Vet your subbies: Ensure any subcontractors you use meet the same high standards you do.
• Check right to work: You must verify that every worker on your site has the legal right to work in the UK.
