The company behind the mothballed Horse Hill oil site in Surrey suspended share trading at 7.30am this morning because of delays to its annual report.

This is the second consecutive year that UK Oil & Gas plc (UKOG) has suspended trading after missing the stock market deadline for publishing its accounts.

In a statement, UKOG said the latest suspension followed a “short delay” to the completion and publication of its audited annual report and accounts for the year to the end of September 2025.

The company said the accounts had been due to be published by the end of business yesterday (Tuesday 31 March 2026).

It told investors:

“The Company anticipates that it will be in a position to publish the ARA [annual report and accounts] very shortly, following which trading in the Company’s shares will be restored. A further announcement will be made in due course.”

In March 2025, UKOG said its auditors needed “additional time”  on the accounts for the year to September 2024. Then, the trading suspension lasted until 1 October 2025.

Planning permission for UKOG’s Horse Hill site was quashed in June 2024 after a landmark climate ruling by the Supreme Court.

The company has said it will reapply for planning permission and would submit additional documents required by the court judgement.

Surrey County Council said it expected to receive the new documents needed for the application by the end of February 2026. A public consultation would then begin. So far, no announcement has been made about the documents or consultation.

• Last month (26 March 2026), Angus Energy announced a delay to the publication of its accounts and suspended share trading. Angus said it expected to publish the acounts on 8 April 2026.
