Interior Design Salary in the UK: Age Bands, Eligibility and What to Expect

Understanding Interior Design Salary in the UK

If you are considering a career in interior design or are already working in the field, knowing what you can expect to earn is essential. The interior design salary in the UK varies by experience, location, employment type, and age band. This guide draws on official data from the Office for National Statistics (ONS), GOV.UK minimum wage rates, and reputable industry sources to give you a clear picture.

Statutory Minimum Wage and Age Bands

All employed interior designers must be paid at least the National Minimum Wage (NMW) or National Living Wage (NLW) depending on their age. From April 2026, the rates are:

• National Living Wage (21 and over): £12.71 per hour
• 18-20 Year Old Rate: £10.85 per hour
• 16-17 Year Old Rate: £8.00 per hour
• Apprentice Rate: £8.00 per hour

These rates are set by the government and apply to all workers, including interior designers. If you are under 21, your interior design salary must meet at least the relevant NMW rate. Many entry-level roles, such as junior interior designer or design assistant, may pay close to these minimums, especially for younger workers. Always check your contract and current statutory rates on UK Minimum Wage for the latest updates.

ONS Data: What Interior Designers Actually Earn

The most reliable source for employed interior design salaries is the ONS Annual Survey of Hours and Earnings (ASHE). For April 2025 (provisional), the data for interior designers (SOC 2020 unit group 3421) shows:

• Median gross annual pay (all employee jobs): £34,962
• Median gross annual pay (full-time jobs): £36,485
• Mean gross annual pay (full-time jobs): £38,597
• Median hourly pay (all jobs): £16.52
• Median weekly gross pay (all jobs): £648.20
• Median paid hours (full-time): 39.9 hours per week

For context, the median full-time employee in the UK earned £39,039 annually, so interior designers sit about 6.5% below the national median. However, interior designers work longer hours on average (39.9 vs 37.5), which brings their weekly pay slightly above the national median (£648.20 vs £642.50). The hourly rate is lower, but the 10th percentile hourly pay for interior designers (£13.34) is above the NLW, meaning even the lowest-paid employed designers typically earn more than the statutory floor.

Career Progression and Pay Bands

Interior design salaries increase significantly with experience. According to Prospects (drawing on SBID income data) and the National Careers Service:

• Junior interior designer: £19,000 – £23,000
• Midweight interior designer: £25,000 – £40,000
• Senior interior designer: £50,000 – £75,000

Recruiter benchmarks from Architecture and Interior Designers Hub tend to be higher, reflecting advertised roles in London and larger practices:

• Graduate: £24,500 – £29,000
• Junior: £27,800 – £32,300
• Midweight: £33,500 – £48,100
• Senior: £47,000 – £69,000
• Design Manager: £46,600 – £61,500
• Associate (8+ years): £64,600 – £80,200
• Associate Director (15+ years): £78,300 – £95,000
• Director: £82,600 – £117,900

These bands show that interior design salary can reach six figures at senior management levels, but most employed designers fall within the £30,000–£50,000 range. For more detailed pay data, visit our pay data page.

Freelance and Self-Employed Interior Designers

Many interior designers work freelance or run their own practice. Day rates for freelancers contracting into studios in 2025 were:

• Midweight: £250 – £320 per day
• Senior: £330 – £400 per day
• Design Director/Lead: £400 – £500+ per day

At 200 billed days per year, a midweight freelancer could gross £50,000–£64,000, which exceeds the employed midweight bands. However, freelancers must cover their own tax, National Insurance, insurance, software licences, and periods without work. Self-employed consultants charge hourly rates of £50–£90 outside London, up to £150 for high-end London work, or flat project fees of £8,000–£15,000 for medium residential projects.

Take-Home Pay Considerations

Your actual take-home pay depends on your tax code, pension contributions, student loan repayments, and benefits. The GOV.UK minimum wage calculator can help estimate net pay. For example, a full-time interior designer earning the median £36,485 would pay income tax and National Insurance, but may also be eligible for pension auto-enrolment. If you are under 21 and earning near the NMW, your take-home pay will be lower, but you may qualify for Universal Credit or other support.

Key Takeaways

• The interior design salary in the UK ranges from around £19,000 for juniors to over £100,000 for directors.
• The ONS median of £34,962 is a solid benchmark for employed designers.
• Age bands affect minimum pay: under-21s must receive at least the NMW rates.
• Freelance and self-employment can offer higher earnings but with more risk.
• Always check your contract and current statutory rates. For more guidance, see our pay guides.
