The verdict in three sentences
For a contract caterer with 22 sites, SaaS at 120 to 350 GBP per site per month adds up to 32,000 to 92,000 GBP a year, while a custom platform at 40,000 to 90,000 GBP (2026 estimate) typically pays back within two years. The deciding factor is Natasha's Law labelling for grab-and-go counters combined with food cost control per contract, because client contracts, subsidies and margin targets differ from one site to the next. If your sites all run the same menu cycle, SaaS is the faster and safer bet.
What UK rules require from your software
Since October 2021, the Food Information (Amendment) (England) Regulations 2019, known as Natasha's Law, require food prepacked for direct sale to carry its name and a full ingredients list with the 14 regulated allergens emphasised. For a contract caterer, that covers sandwiches, salads and pots made on site and sold from a chiller. Loose items still need allergen information available on request, and the Food Standards Agency publishes the reference guidance.
| Requirement | What the software must do | Risk without it |
|---|---|---|
| PPDS labels | Print compliant labels from the live recipe, allergens in bold | Hand-written or outdated labels |
| Recipe substitutions | Recalculate allergens when a supplier swaps a product | Wrong label on a supplier change |
| 14 allergens on menus | Publish allergen matrices per site and per day | Front-of-house guessing |
| Food cost per contract | Theoretical vs actual cost per cover, per site | Margin erosion found at month end |
| Purchasing | Orders generated from menus and forecast covers | Overstock and waste |
| Client reporting | Monthly packs on spend, waste and sustainability | Spreadsheets rebuilt for every client |
Custom or SaaS: the 5-year view
Figures are 2026 market ballparks in GBP, excluding VAT, for 22 sites.
| Criterion | Catering SaaS | Custom platform |
|---|---|---|
| Setup | 3,000 to 12,000 GBP | 40,000 to 90,000 GBP |
| Recurring cost | 120 to 350 GBP per site per month, or 31,700 to 92,400 GBP a year | Hosting and maintenance: 12 to 15% of build per year |
| 5-year total (midpoint) | 7,500 + 310,000 = about 317,500 GBP | 65,000 + 44,000 = 109,000 GBP |
| Label printing for grab-and-go | Usually included | Built for your printers and formats |
| Contract-level margin rules | Limited | Per client: subsidies, tariffs, targets |
| Covers forecasting | Basic | Trained on your history and client calendars |
| Time to go live | 1 to 3 months | 4 to 6 months |
Below eight sites, SaaS nearly always wins. As a nearshore option, Kolonell's prices for a complex application start at 10,670 EUR (7,000,000 FCFA) and exceed 22,870 EUR (15,000,000 FCFA) depending on scope, which suits a focused module such as the PPDS labelling and food cost layer next to an existing SaaS.
Mini case study
Illustrative example: Priya, operations director of a London contract caterer with 22 office and campus sites serving 9,000 covers a day.
- Custom platform: 70,000 GBP, maintenance 9,800 GBP per year.
- Volume: 9,000 covers over 240 trading days, or 2,160,000 covers at 2.40 GBP food cost: 5,184,000 GBP of purchases.
- Waste: 8% of purchases, or 414,700 GBP, cut by 15% through forecasting: 62,200 GBP per year.
- Food cost drift: catching overspend weekly instead of monthly recovers 0.5% of purchases, 25,900 GBP per year.
- Avoided SaaS at 220 GBP per site per month: 58,080 GBP per year, which Priya keeps as the comparison baseline.
- Net annual gain versus today: 88,100 minus 9,800, or 78,300 GBP, for a payback of about 11 months.

FAQ
How much does custom contract catering software cost in London?
A 2026 estimate is 40,000 to 90,000 GBP for 15 to 30 sites. Add 12 to 15% a year for hosting and support.
Does Natasha's Law apply to contract caterers?
Yes, when food is prepacked on site for direct sale, for example sandwiches in a staff restaurant chiller. Each label must show a full ingredients list with the 14 allergens emphasised.
Can the system print labels automatically?
Yes, labels print from the live recipe so any substitution updates them. Most caterers use 1 or 2 label printers per site.
How much waste reduction is realistic?
A 10 to 20% cut within 12 months is a reasonable target when orders follow forecast covers. On 5 million GBP of purchases, that is well above 50,000 GBP.
Can it report to each client separately?
Yes, monthly packs on spend, waste and sourcing are generated per contract. That saves 2 to 4 hours per site per month for site managers.
