The UK Delivery Benchmark

Lessons from 100 Mystery Shops During Peak

£36 Billion lost at Checkout Newspaper Headline
  • £36bn worth of non-food baskets are still abandoned

  • 73% of high-value shoppers are the most likely to abandon

  • 73% of shoppers are less likely to buy again from a retailer that fails on the delivery promise

What Makes This Report Different

This is the UK’s most comprehensive delivery benchmark built on two powerful datasets:

1. Nationally representative shopper insight
2,000 UK consumers sharing what they expect from delivery today

2. Real-world mystery shopping
100 orders placed with 100 UK retailers during Peak, tracking the full delivery experience from checkout to doorstep

We didn’t ask retailers what they offer.

We tested what customers actually experience.
