The Bottom Line First
A well-run independent Thai restaurant (40-60 covers) in a UK regional city typically does £250,000–£450,000 annual turnover with a net profit margin of 5-10% after all costs including owner salary. That's £12,500–£45,000 net profit per year for the owner — on top of their working salary.

Where the Money Goes
For a typical mid-size Thai restaurant turning over £350,000/year:
| Cost Line | % of Revenue | Annual £ at £350k |
|---|---|---|
| Food & ingredient costs | 25-32% | £87,500–£112,000 |
| Staff wages (inc. NI, pension) | 30-38% | £105,000–£133,000 |
| Rent & business rates | 8-15% | £28,000–£52,500 |
| Utilities (gas, electric, water) | 3-6% | £10,500–£21,000 |
| Delivery commissions | 2-8% | £7,000–£28,000 |
| Marketing & platform fees | 1-3% | £3,500–£10,500 |
| Insurance, licences, legal | 1-2% | £3,500–£7,000 |
| Repairs & maintenance | 1-2% | £3,500–£7,000 |
| Other (linen, cleaning, waste, POS) | 2-4% | £7,000–£14,000 |
| Total costs | 73-90% | £255,500–£315,000 |
| Net profit (before owner drawings) | 10-27% | £35,000–£94,500 |
Important: The 10-27% "net profit" includes the owner-operator's salary. If you work in the restaurant as head chef or manager, your market-rate salary (£30,000-£45,000) comes out of this. The true surplus after paying yourself is typically 5-10%.
Owner Take-Home Reality
Most Thai restaurant owners in the UK work in the business. Here's what that actually looks like:
- Sole owner-operator chef: £35,000–£55,000 total (salary + profit). Effectively working for £14-20/hour for 60+ hour weeks
- Owner-manager with employed chef: £40,000–£70,000. Better work-life balance but higher wage bill
- Multi-site owner (2-3 locations): £80,000–£180,000. Economies of scale kick in
- Absentee owner: Rare in Thai independents. If fully managed, expect 2-5% return on investment after paying a manager
The Delivery Impact on Profit
This is critical for Thai restaurants specifically. A £13.50 Pad Thai sold dine-in might net £5.40 after food cost. The same dish on Deliveroo at 32% commission:
- £13.50 + 20% VAT = £16.20 customer price
- Deliveroo takes 32% = £5.18
- You receive: £11.02 before VAT
- Food cost at 28%: £3.78
- Gross profit: £7.24 dine-in vs £4.24 delivery
Delivery dilutes margin by 30-40% per dish. A restaurant doing 40% delivery might show strong revenue but thin profit. Use our Profit Margin Defender to stress-test your delivery mix.
Revenue Drivers — What Moves the Needle
- Average spend per head: £18-22 for casual Thai, £28-40 for premium. Upselling starters, sides, and drinks is the highest-leverage profit move
- Table turnover: 1.5 turns/night is average. 2+ turns doubles revenue without increasing fixed costs
- Delivery mix: Keep it under 30% of revenue unless you've priced specifically for platform commissions
- Alcohol sales: The highest-margin category. A drinks list that pairs with Thai food (Singha, Thai iced tea, mango sticky rice cocktails) adds 15-20% to average spend
- Lunch trade: Often neglected by Thai restaurants. A £10-12 lunch menu can add £30,000-£60,000/year with minimal extra cost
What the Numbers Don't Tell You
These are benchmarks, not guarantees. A Thai restaurant in a high-footfall city centre will outperform one on a suburban high street with no parking. A restaurant with a strong Google presence (see our marketing guide) will fill more tables than one relying on walk-ins. The difference between the 75th and 25th percentile is often £100,000+/year — and it's usually driven by location, marketing, and operational discipline, not the quality of the pad thai.
