Salary Sacrifice for Car: Comparing Hourly Jobs with Salaried Offers

When weighing up a job offer, it’s easy to focus on the headline hourly rate or annual salary. But if your employer offers a salary sacrifice for car scheme, the numbers on your payslip can look quite different from what you expected. Understanding how salary sacrifice interacts with hourly pay, annual salary, and legal minimums is essential – especially if you’re moving between hourly and salaried roles.

What Is a Salary Sacrifice for Car?

A salary sacrifice for car (often called a company car scheme or car lease through work) lets you give up part of your gross pay in exchange for a non-cash benefit – in this case, a vehicle. The sacrificed amount is deducted before tax and National Insurance, so you pay less income tax and NI. However, your cash take-home pay is lower. The key point for UK employees is that your cash pay after sacrifice must not fall below the National Living Wage (NLW). As of April 2025, the NLW for employees aged 21 and over is £12.21 per hour. The Office for National Statistics (ONS) Annual Survey of Hours and Earnings (ASHE) for 2025 shows that median hourly earnings for full-time employees were £19.67, and median annual earnings were £39,039. These benchmarks help you see where your pay sits.

Hourly vs. Salaried: How the Conversion Works

To compare hourly and salaried offers, use the standard rule: annual salary ≈ hourly rate × hours per week × 52 weeks. For a typical full-time week of 37.5 hours, an hourly rate of £12.21 gives an annual salary of about £23,809.50 (the 2025 NLW level). At the median hourly rate of £19.67, the annual equivalent is roughly £38,356.50 – close to the ONS median of £39,039. But remember: this conversion assumes a steady 37.5-hour week with no unpaid overtime, bonuses, or salary sacrifice. In reality, your actual pay depends on your rota, holiday pay method, London weighting, and overtime rules.

How Salary Sacrifice for Car Changes the Picture

If you opt for a salary sacrifice for car, your gross pay reduces. For example, suppose your base hourly rate is £15.00 and you work 37.5 hours a week. Your annual gross pay before sacrifice is £29,250. If you sacrifice £2,500 a year for a car, your gross pay becomes £26,750 – equivalent to an hourly rate of about £13.72. That’s still above the NLW, so it’s legal. But if you’re on a lower rate, say £12.50 per hour (annual £24,375), sacrificing £2,500 would drop your cash pay to £21,875, or about £11.22 per hour – below the NLW. That’s why employers must monitor compliance, as highlighted in the NHS Pay Review Body’s 38th Report (NHSPRB 2025). The report notes that salary sacrifice arrangements, including car lease schemes, can push cash pay below the NLW threshold, creating challenges for trusts.

London Weighting and HCAS

If you work in London or the South East, you may receive a High-Cost Area Supplement (HCAS). For NHS staff in 2026/27, Inner London attracts 20% of basic salary (min £5,794, max £8,746), Outer London 15%, and Fringe 5% (NHS Employers). These supplements are added to your basic pay before any salary sacrifice. So if you’re on an NHS Band 6 role with a basic hourly rate of £20.44 (2026/27 rate) and you work in Inner London, your total hourly rate including HCAS could be around £24.53. A salary sacrifice for car would then be deducted from the combined gross, but the cash rate must still meet the NLW. For hourly workers, this can get complicated because overtime and unsocial hours payments are often calculated on basic pay, not the reduced rate.

Overtime and Pension Implications

Hourly workers often rely on overtime to boost earnings. If you’re on a salary sacrifice for car, overtime pay is typically based on your basic hourly rate before sacrifice, not the reduced cash rate. That’s good news – your overtime rate stays intact. However, pension contributions (especially in defined benefit schemes like the NHS Pension Scheme) are usually calculated on your pensionable pay, which may be the gross pay before sacrifice. By reducing your gross pay, you could lower your pension contributions and future benefits. The NHSPRB report also warns that salary sacrifice can affect eligibility for certain benefits if cash pay dips below thresholds.
