Important Notes — 2025/26 Rates & Caveats
UK spa and beauty treatment benchmarks 2025: 60-minute facial £60–120; full body massage £60–90; manicure £25–45; pedicure £35–55; LVL lash lift £55–80; gel manicure £35–55; spray tan £30–45. Luxury day spas charge 30–50% above these rates. Room occupancy of 60–70% is typically target for a well-run beauty salon; day spas often achieve 50–65%. Therapists are often paid on a commission basis (30–40% of treatment revenue) rather than a fixed wage — model both scenarios.
Frequently Asked Questions
What is a typical occupancy rate for a UK beauty salon or spa?
A well-run beauty salon targets 60–70% occupancy across treatment rooms during operating hours. Day spas, which have longer appointment gaps for setup and client relaxation time, typically achieve 50–65%. Occupancy below 50% typically indicates pricing or marketing issues; above 80% suggests the business is capacity-constrained and could support higher pricing or additional rooms.
Should spa therapists be employed or on commission?
Both models are common in the UK. Employed therapists on a fixed wage provide predictable labour costs; commission-based arrangements (typically 30–40% of treatment revenue) align therapist earnings with productivity. Commission models can incentivise upselling and retail sales. Employed therapists provide more employment protection and are more likely to deliver a consistent service standard. The choice depends on management preference, local labour market and treatment mix.
What retail margin should a spa or beauty salon target?
Retail product sales (skincare, hair care, nail products) are an important high-margin revenue stream for spas and salons. Gross margin on professional beauty retail products is typically 40–60%. A treatment room delivering 4 treatments per day has 4 natural opportunities to recommend retail products — even a 20% retail purchase rate at £30 average spend adds £6/treatment day to revenue. Successful spas target retail at 10–20% of total revenue.
