How to Open a Thai Restaurant
in the UK

Real costs, real numbers, real steps. Everything the generic "how to open a restaurant" guides leave out — specifically for Thai cuisine operators.

What It Actually Costs

Based on 2026 figures. Ranges depend on location, size, and whether you're taking over an existing restaurant or starting from an empty unit.

£80k–£180k
Total startup (leasehold, 40–60 covers)
£15k–£35k
Kitchen fit-out (wok stations, extraction, refrigeration)
£8k–£20k
Front-of-house (furniture, decor, POS, tableware)
£3k–£8k
Legal & licensing (premises licence, solicitor, planning)
£5k–£10k
Pre-opening (staff training, marketing, soft launch)
£5k–£15k
Initial stock (dry goods, fresh, bar)
£8k–£18k
Chef visa sponsorship (if recruiting from Thailand)
3–6 months
Working capital buffer (rent, wages, suppliers)
Saving money: Taking over a former restaurant with a working extraction system and commercial kitchen can cut startup costs by £20k–£40k. The single biggest cost variable is whether the unit already has a commercial extraction canopy — installing one from scratch in a new unit runs £15k–£25k alone.

The 15-Step Roadmap

What Makes Thai Restaurants Different

🔥 The Wok Station Problem

Thai cooking runs on high-BTU wok burners. A standard commercial kitchen gas supply may not be adequate — you may need a upgraded gas line (budget £2k–£5k). The extraction system must handle heavy smoke, oil vapour, and chilli fumes. This isn't a pizza oven or a chargrill — it's constant high-temperature stir-frying. Many landlords don't understand this. Negotiate gas infrastructure costs into your lease.

🌿 The Ingredient Supply Chain

Unlike Italian or French cuisine, core Thai ingredients (galangal, kaffir lime leaves, Thai sweet basil, bird's eye chillies, shrimp paste) can't be sourced from standard foodservice suppliers. You need a Thai-specific importer — and you need a backup. The main players: Lung Wah Chong (London, established 1987, ships nationwide), Thai Food Online, Star Imports, and regional Asian wholesalers in Birmingham, Manchester, and Glasgow. Minimum orders, seasonal availability, and import delays are real — keep 2 weeks of dry stock minimum.

👨‍🍳 The Chef Visa Reality

This is the biggest bottleneck for UK Thai restaurants. The Skilled Worker visa for Thai chefs requires: a sponsor licence (£536–£1,476 depending on business size), a Certificate of Sponsorship (£239), the Immigration Skills Charge (£364–£1,000/year), and the minimum salary (£38,700 or going rate). Total first-year cost: £8,000–£15,000 before the chef's salary. And processing takes 3–6 months. Run our Visa Assistant →

📋 Hygiene Rating Expectations

Thai restaurants perform well on FSA inspections — 56.7% score a 5. The key inspection areas for Thai kitchens: wok station cleanliness (oil build-up is the #1 issue), rice handling (cooked rice must be cooled within 90 minutes and stored below 8°C), and shellfish storage. A rating of 3 or below will cost you customers — diners check ratings.

⚡ The honest truth most guides won't tell you

Thai restaurants have higher GP margins than most cuisines (75–85% on curries and stir-fries) but they face unique cost pressures: chef visa costs (£8k–£15k upfront), ingredient supply chain fragility (import delays on Thai-specific items), and heavy energy costs (wok cooking is gas-intensive). The restaurants that survive the 2026–2028 period will be the ones that: (1) priced their menu using real data, not guesswork, (2) secured a Thai chef before the visa rules tighten further, and (3) built a delivery menu that's actually profitable. Everything else is secondary.
