London minimum wage enforcement guidance

Enforcement of the Minimum Wage

UK employers, payroll teams, and business owners responsible for ensuring compliance with National Minimum Wage (NMW) and National Living Wage (NLW) regulations. The government’s enforcement strategies for NMW/NLW, how HMRC monitors compliance, penalties for underpayment, and the current rates effective 1 April 2025. Non-compliance can result in wage arrears, fines, director disqualification, and potential criminal prosecution. Understanding enforcement strategies helps businesses proactively ensure compliance.

HMRC’s Enforcement Strategies

The Department for Business & Trade and HMRC enforce NMW and NLW through a strategy known as Promote, Prevent and Respond:

  • Promote: Focuses on educating employers to prevent accidental non-compliance by providing clear guidance and information. Accountants can help businesses understand their obligations and avoid mistakes.

  • Prevent: Targets employers who intentionally underpay workers, highlighting consequences to deter breaches.

  • Respond: Applied when non-compliance is identified via complaints or targeted inspections. HMRC may issue a Notice of Underpayment (NoU) requiring repayment within 28 days, impose penalties, and in serious cases pursue criminal prosecution.

Enforcement Budget and Impact

  • The enforcement budget increased from £31.2 million (2023–24) to £31.5 million (2024–25).
  • This allows HMRC to expand compliance teams and investigative activities to protect workers’ rights and improve wage compliance.

Current NMW and NLW Rates

  • National Living Wage (NLW): £12.21 per hour for workers aged 21 and over
  • National Minimum Wage (18–20 years old): £10.00 per hour
  • National Minimum Wage (16–17 years old) and Apprentices: £7.55 per hour

Real-World Application for Employers

  • Payroll audit: Regularly review payroll to ensure all employees are paid at least the legal minimum.
  • Compliance monitoring: Track hours, standby, and travel to correctly calculate working time under NMW rules.
  • Employee communication: Clearly explain wage rates and entitlements to reduce accidental non-compliance.

Risks and Penalties

  • Repayment of underpaid wages within 28 days as required by HMRC.

  • Penalties imposed for non-compliance, including fines and potential public naming.

  • Labour market enforcement undertakings for serious breaches.

  • Criminal prosecution in the most severe cases. Businesses can consult a local accountant Wimbledon to ensure compliance and minimise risks.

I'm Aitch, the Founder and CEO of CIGMA Accounting Ltd. As a Chartered Management Accountant and as a CIMA member, I've spent more than 16 years helping businesses, entrepreneurs, landlords, and individuals with tax planning, accounting, and HMRC compliance. As a chartered accountant in London, I'm passionate about making complex tax matters easier to understand and helping clients make confident financial decisions. Over the years, I've advised start-ups, SMEs, established companies, and high-net-worth individuals across a wide range of tax and accounting matters. My expertise includes Corporation Tax, Self-Assessment, Capital Gains Tax, Inheritance Tax planning, R&D tax relief, capital allowances, international tax, and resolving complex HMRC compliance issues. Whether clients need a business accountant, tax accountant, or strategic tax advisor, my focus is always on delivering practical advice that creates long-term value. One of my specialist areas is Making Tax Digital (MTD). I've worked extensively with businesses preparing HMRC's digital reporting requirements, helping them move to cloud accounting, improve financial processes, and adopt technology that makes compliance more efficient. I regularly speak at Making Tax Digital roadshows, industry events, and educational sessions in collaboration with Zoho Books, sharing practical insights into digital accounting, tax legislation, and the future of the profession. Many business owners looking for the best accounting firm in London are not simply searching for an accountant they're looking for trusted advice, responsive support, and long-term value.
