Big ideas for UK Retailers and 3PLs to deal with all the cost shocks: £2.00+ diesel, £12.71 wages and new rates.
UK retailers and 3PLs are absorbing their second cost shock in 18 months. This time it arrives on every line of the logistics P&L at once.
In April 2025 it was National Insurance. In April 2026 it was the National Living Wage and a business rates revaluation. Since July, it has been energy. The Bank of England now expects inflation to go slightly above 4% in early 2027, with Brent crude up 36% and UK wholesale gas up 78% since the summer and is even higher at the time of writing. Average diesel has risen to over 200p per litre this week. For an operation running on a 2–3% margin, that is not background noise. It is the difference between a profitable contract and a loss-making one.
The cost stack, line by line
- A full-time warehouse operative on the National Living Wage cost an employer about £24,100 a year in wages and National Insurance in 2024–25. Today the same person costs about £27,750, up 15% in two years. In most DCs labour is the biggest cost, so this line alone moves cost per order.
- Logistics UK reports diesel up 36% and driver costs up about 8% in the year to April 2026, before the latest fuel spike.
- Industrial rateable values rose 21.1% on average in the 2026 revaluation. Around 1,900 large distribution warehouses, including retailers’ own DCs now pay a higher multiplier to fund lower rates on the high street: about £28,000 a year for every £1m of rateable value and a total of £270m over three years. Prime warehouse rents have risen by over 17% in the last three years.
- Automated and chilled operations carry the most exposure to wholesale power and gas.
Why price rises alone won’t fix it
Shoppers are spending, but carefully. Retail volumes were up 2.4% year on year in August and online hit a record 28.8% of sales. Yet in the BRC’s February survey, 84% of retail finance chiefs ranked labour and employment costs among their top three concerns. Passing costs on has limits when customers compare prices on their phones.
That leaves the operation itself. In our experience the fastest savings come from the sites, fleets and contracts businesses already have. Where is the opportunity in your operation? →
What we have seen work
- Productivity first. For a European fashion brand, a warehouse performance review found a 9.7% productivity saving worth €3.3m.
- Network before new build. For a major UK health and beauty retailer, we redesigned the network to absorb 35% volume growth while reducing cost to serve by 3%.
- Know your cost to serve by channel. Most businesses know their total logistics bill. Few know what the true operational cost to serve components are; a store replenishment case, a home delivery order and a return each cost. Without that, every pricing and proposition decision is a guess.
Three questions to ask this month
- What has our cost per order moved by since April 2025, and which line drove it?
- Which of our sites or contracts are now below target margin?
- Where could we release 10% more output from existing labour and space before peak?
Over the next seven weeks we will take each of these in turn, from productivity and the Employment Rights Act to network strategy, automation and 3PL buying. In week 4 we will publish The UK Cost-to-Serve Squeeze 2026, with a practical model you can apply to your own operation.
Could your supply chain be working harder?
Rising costs don’t automatically mean adding more people, space or technology. The opportunity may already exist within your operation.
