Planning a party for 50, 100, or 200 guests and trying to work out what South Indian and Sri Lankan catering will cost in London? You are not alone. Guest count is one of the biggest factors in your final catering bill. Most price guides online do not break it down clearly.
Quick answer: South Indian and Sri Lankan catering in London usually costs £15 to £45 per guest. The exact price depends on your menu, service style, and guest count. Larger events often cost less per head, because bulk cooking spreads fixed costs across more portions.
This guide breaks the numbers down by guest count. It shows what changes your final price. It also shows how to plan portions so nobody leaves hungry.
What Affects the Cost of South Indian & Sri Lankan Catering
Every quote you get will depend on a few core factors.
Guest Count and Menu Choice
Smaller events pay more per head. Larger events get bulk pricing. A simple three-curry buffet also costs less than a menu with live dosa stations, seafood, or lamb dishes.
Service Style, Timing, and Extras
Buffet service is usually cheaper than staffed, plated service. Weekday and daytime events often cost less than weekend evenings. Live counters, extra desserts, and longer staffing hours all add to the total bill.
Poptop, a UK catering marketplace, puts the average cost for Indian catering across London at around £18–£19 per guest (Poptop, 2024, poptop.uk.com). Your final figure moves up or down based on the factors above.
Catering Cost by Guest Count
Here is a general breakdown of what South Indian and Sri Lankan catering tends to cost in London at three common event sizes.
| Guest Count | Typical Per-Head Range | Estimated Total Range |
| 50 guests | £22 – £35 | £1,100 – £1,750 |
| 100 guests | £18 – £30 | £1,800 – £3,000 |
| 200 guests | £15 – £25 | £3,000 – £5,000 |
These ranges are estimates. They come from published London catering-market data (Poptop, 2024) and general pricing tiers reported by UK caterers. They are not one single fixed source. Your actual quote depends on your menu and requirements — contact Chennai Spice for a personalised price.
Why Smaller Events Cost More Per Head
At a 50-guest event, fixed costs like staff travel, setup, and equipment hire get shared across fewer plates. At 200 guests, caterers buy ingredients in bulk and use kitchen staff more efficiently. That is why the per-head rate drops as guest numbers rise.
For context, a 150-guest South Indian wedding buffet in London typically costs £4,000 to £6,000 for a standard package. This comes from Chennai Spice’s own South Indian Wedding Catering Cost guide (Chennai Spice, 2026, chennaispice.com). That range lines up closely with the 100–200 guest figures above.
How Portion Planning Changes by Guest Count
Getting portions right matters as much as getting the price right. Indian and Sri Lankan food is usually served buffet-style, and guests tend to sample several dishes rather than take one large plate.
Baseline Portion Guide
UK Indian catering data suggests a working baseline of 400–500g of total food per guest for a main meal buffet (Jaflong Tandoori Catering, 2026, jaflongcatering.com). That typically breaks down as:
- Rice – around 150g per guest
- Curries (2–3 options) – around 200g per guest combined
- Bread (naan, roti, or paratha) – around 50g per guest
- Starters or snacks – around 100g per guest
Common mistake to avoid: Under-ordering is the most common error in Indian and Sri Lankan event catering. Guests sample many dishes instead of taking one plate, so a menu planned like a Western sit-down meal often runs out. Always confirm portion weights with your caterer, not just the number of dishes on the menu.
Menu Options at Each Price Tier
Your menu choice moves your final cost more than almost any other factor.
£15–£22 Per Head
A simple buffet with 2–3 curries, rice, and bread. Good for large, casual gatherings where volume matters more than variety.
£22–£30 Per Head
A fuller buffet with 3–4 curries, sides, and a dessert. This is the range most family celebrations and office parties choose.
£30–£45 Per Head
A premium spread with 5+ dishes, specialty items such as biryani or seafood, live counters, and dessert stations. Common for milestone birthdays, engagement parties, and larger celebrations.
Choosing mostly chicken and vegetarian mains keeps costs down. You still get plenty of variety, without paying extra for lamb or prawn dishes.
Tips to Get the Best Value for Your Event Size
- Book weekday or daytime slots where possible — many venues and caterers price these lower than weekend evenings.
- Confirm guest numbers early so your caterer can quote bulk pricing accurately.
- Ask for a mixed menu of chicken, vegetarian, and one premium dish rather than an all-premium spread.
- Check what is included — some quotes cover only food, while others include serving staff, equipment, and cleanup.
- Request a tasting if you are booking for 100+ guests, so the menu is confirmed before the big day.

Not usually. Price depends more on the dishes, the meat or seafood content, and the service style. The cuisine type matters less.
