Understanding Interior Design Salary in the UK

If you're exploring a career in interior design or considering a move, knowing the typical interior design salary is essential for negotiating pay and planning your finances. Unlike some professions with clear pay scales (such as teaching or nursing), interior design salaries in the UK are not published as a standalone category by the Office for National Statistics (ONS). Instead, interior designers are likely grouped under broader occupational headings like 'design occupations' or 'artistic, literary and media occupations'. This means we need to use general UK earnings benchmarks and industry knowledge to estimate realistic pay.

Hourly to Annual Conversion: The Basics

To convert an hourly rate to an annual salary, a common rule of thumb is:

Annual salary ≈ hourly rate × hours per week × 52 weeks

For a standard full-time week of 37.5 hours (common in many design studios), the formula becomes:

Annual ≈ hourly × 1,950 (since 37.5 × 52 = 1,950)

For example, at the National Living Wage (NLW) of £12.21 per hour (April 2025 rate for those aged 21+), the annual equivalent is roughly £23,809.50. At the UK median full-time hourly pay of £19.67 (ONS ASHE 2025), the annual equivalent is about £38,357. Remember, these are gross figures before tax and National Insurance.

What the Official Data Says

ONS ASHE (Annual Survey of Hours and Earnings) provides the most authoritative picture of UK pay. In April 2025:

• Median full-time weekly earnings: £766.60
• Median full-time annual earnings (for those in the same job for at least a year): £39,039
• Median full-time hourly pay (excluding overtime): £19.67

These figures cover all occupations. For interior design specifically, the ONS does not break out a separate figure. However, the broader 'design occupations' category (which includes graphic designers, product designers, and interior designers) typically has median earnings close to the national average, with a wide range from entry-level to senior roles.

Regional Differences in Interior Design Pay

Location heavily influences interior design salary. London and the South East command higher pay due to higher living costs and concentration of high-end projects. ONS data shows that in April 2025, median full-time weekly earnings in London were £866.20, compared with £766.60 nationally. A 'London weighting' of 10–20% is common in many design firms.

Other regions vary:

• South East: often 5–10% above national median
• Scotland, North West, Midlands: close to national median
• Northern Ireland: lower levels but highest growth (7.4% in 2025)
• Wales and North East: typically below national median

Seniority and Experience Levels

Interior design salaries increase significantly with experience and portfolio strength:

• Junior/Assistant Designer: Often starts near the National Living Wage (£12.21/hr) or slightly higher, equating to £23,000–£25,000 annually.
• Mid-weight Designer: With 3–5 years' experience, hourly rates of £15–£20 are common, annual £29,000–£39,000.
• Senior Designer/Associate: 5–10 years' experience can command £20–£30 per hour, annual £39,000–£58,500.
• Design Director/Head of Studio: Often £30–£50 per hour, annual £58,500–£97,500 or more, especially in London.

Freelance interior designers often charge higher hourly rates (£25–£60) to cover overheads, but income can be irregular. Always factor in unpaid time for marketing, admin, and holidays.

Overtime, Bonuses, and London Weighting

Many interior design roles involve overtime, especially before project deadlines. Your contract should specify whether overtime is paid (often at time-and-a-half) or 'time off in lieu'. Bonuses are less common than in finance but may be offered in larger firms.

London weighting is a key factor. A role advertised at £30,000 in London might be equivalent to £25,000 elsewhere. Always check if the salary includes a London allowance or if it's negotiable.

Using the National Living Wage as a Floor

The National Living Wage (NLW) for workers aged 21+ was £12.21 per hour in April 2025. This is the legal minimum for most employees. Any interior design role paying below this (unless you're an apprentice or under 21) is likely non-compliant. The NLW is set to rise annually; the 2026/27 rate is expected to increase further.

Where to Find More Data

For detailed pay data by occupation, the ONS publishes ASHE Table 2 (two-digit SOC) and Table 29 (industry and occupation). You can explore these on the salary data page. For personalised calculations, use our hourly calculator.

Summary

While a precise interior design salary figure is not officially published, the UK median full-time hourly pay of £19.67 provides a useful benchmark. Actual pay varies by region, seniority, and whether you work in-house or freelance. Use the conversion rule of thumb (hourly × 37.5 × 52) to estimate annual equivalents, and always check your contract for overtime and London weighting. For more insights, browse our topics section.
