The maths
Saving = commission × share moved to direct
Kept = saving − ad spend
Worked example
A takeaway does 600 app orders a month at £24, which is £14,400 of sales. At 30% plus VAT across the apps, that is £5,184 a month in commission, over £62,000 a year. Moving a quarter of those orders to its own ordering page saves £1,296 a month. Spending £500 on local Meta ads to make that happen leaves £796 a month, around £9,500 a year, and the customer details stay with the takeaway rather than the app.
What the rates are based on
Uber Eats publishes its UK rates on its merchant pricing page: 30% for Uber delivery, 13% self-delivery and 13% pickup, excluding VAT (checked 30 September 2026). Just Eat and Deliveroo set rates by contract, so the defaults here are placeholders at the same 30% and you should replace them with your own.
