Police investigating the cause of an explosion and fire at a house in Cleat Hill, Bedford, in October 2024 have renewed their appeal for anyone who worked on the building site to come forward.

The explosion happened on the morning of 19 October after a major gas leak was struck during construction work to install a ground source heat pump at the property. Emergency services were called just after 7.30am. A man was found dead at the scene, and a woman rescued by a member of the public later died in hospital.

The property was owned by Paul Swales, who lived there with his sister-in-law, Julia Harris. Mr Swales had hired a building company to construct an annex at the rear of the house. The drilling work, which involved making a 110-metre borehole, was subcontracted to another firm. On 2 July 2024, the drilling team struck a pocket of natural gas. Responders put in place methods to vent the gas, but management of the release was later handed back to the drilling company.

Detective Inspector James Day from Bedfordshire Police said: “If you were a worker on the building site and we haven’t already spoken to you, or know of anyone who was working there, please get in touch with us. You may have information that could assist our investigation.”

Police continue to investigate the cause with support from the Health and Safety Executive. A coroner’s inquest into the deaths has been adjourned until 14 January 2026, while forensic and technical examinations continue.

Anyone with information is asked to contact Bedfordshire Police on 101 or online quoting Operation Quickdraw.
