Temporary Surcharge – Explained

Since the conflict in the Middle East began in March, the price of fuel has jumped significantly and remains extremely volatile. This doesn’t only affect us — it has impacts all the way through the supply chain including partners, suppliers and producers.

We’re introducing a small, temporary Surcharge. We’ve worked this out to offset the additional cost we’re currently facing, and we’ll review it every month to make sure it stays fair.

Here’s exactly how it works

  • It’s 26p per week. Order as often as you like — your service doesn’t change, and the charge stays the same for the week.
    • For our Member’s who pay monthly: it’s £1.14 per month 
  • It never touches product prices. Your milk costs aren’t affected. You’ll see the charge listed clearly in your weekly total.
  • We review it monthly. On the 1st of every month, we check it against the official UK diesel price. If fuel prices fall, the charge falls too. Once diesel drops below £1.55 a litre, the charge disappears completely — and we’ll confirm the update to you each month.
  • It’s capped at 34p. Whatever happens to fuel prices, it will never go above that.

The mechanism

We review it on the 1st of every month against the official GOV.UK weekly diesel price, using the bands below, and it’s removed automatically once diesel falls back below £1.55/litre.

Why is there a fuel charge on my bill? Since the conflict in the Middle East began in March 2026, UK diesel prices have jumped — from around £1.44 a litre in January to a peak of £1.92 in April, and £1.79 this week (official GOV.UK figures). Rather than putting up product prices, we’ve added a small, temporary weekly charge that covers part of the extra cost of getting your order to your doorstep — and that’s built to be removed when fuel settles down.

How much is it? It’s worked out, not made up. Getting your order to your doorstep takes about three-quarters of a litre of diesel per household each week, so we charge the difference between this month’s official GOV.UK diesel price and the £1.44 a litre we planned the year around — nothing more. On the 1st of every month we recalculate using the bands table above. Right now it’s 26p a week.

Is it per delivery? No — it’s per week you receive deliveries, however many drops you get. We’d never charge you more for ordering more often.

I pay monthly — how does it work for me? Exactly the same, just once a month: the weekly amount ×.4.4 (average number of weeks in a month), shown as a single line on your monthly bill (£1.14 right now). Over a year it comes to the same as weekly members pay — your plan doesn’t change what fuel costs you.

Will it ever go up without warning? No. It only moves on the 1st of the month, only by the published formula, it’s capped at 34p a week, and we’ll tell you every time it changes — up or down.

When will it be removed? The moment the monthly GOV.UK diesel price falls below £1.55 a litre, the charge comes off every account automatically. You don’t need to do anything, and we’ll email you when it happens.

Where do the fuel prices come from? The UK government’s weekly road fuel price statistics, published every Tuesday: gov.uk/government/statistics/weekly-road-fuel-prices. Same numbers anyone can check.
