Diesel price record for contracts: Great Britain
The weekly official diesel price for Great Britain, kept as a record you can point to: 5 weekly figures from 13 October 2025 to 19 October 2026, with the publisher, the licence and a SHA-256 hash so nothing can change unnoticed.
This page is information, not legal, tax or financial advice, and ProofPrice is not a party to your contract. Have your own adviser check any clause. The figures are an official statistic published by Department for Energy Security and Net Zero (DESNZ), United Kingdom; they are not asking prices and not the price at any one station.

The library started keeping this series in October 2026, so the weekly table is short and grows every week; earlier years are shown as monthly averages below.

How to cite this in a contract
A clause that adjusts a price with the diesel price should name the series, the publisher, the day it is read and what happens if it disappears. Wording you could adapt:
The diesel price for Great Britain is the national average pump price of diesel (automotive gas oil) published by Department for Energy Security and Net Zero (DESNZ), United Kingdom in Weekly road fuel prices, for the Monday of the relevant week, in GBP per litre, with duties and taxes included, as recorded at https://proofprice.com/fuel-clause/gb. If the publisher restates or stops publishing the figure, the parties will use the closest successor series published by the same body.
Cite the publisher as the primary source and this page as the record of the figures. State whether your clause means prices with or without VAT: this series includes all duties and taxes. Whether and how a figure is binding is for your contract and your adviser, not for this page.
