A FIRE that damaged a Conservation Area building in Bradford city centre was caused by a faulty electrical supply – fire investigators have found.

A fire in the upper floor space of a café in a converted mill on Grattan Road on June 4 has been one of the biggest call outs by West Yorkshire Fire Authority in the past few months.

The blaze, which began shortly after 4am, saw 12 fire engines and 72 firefighters scrambled to the building, just off Thornton Road.

More details of the fire have been revealed in a report by West Yorkshire Fire Authority that looks at some of the biggest fires the service has been called to since the start of the financial year in April.

Fire crews from as far as Dewsbury and Halifax were sent to back up crews from Bradford stations, and hazmat officers and a fire investigation crew were also sent to the site.

The situation was closed at around 10am.

Blaze attended by 66 firefighters thought to have been caused by 'child playing with fire'

The roof of the building, which sits within Bradford’s historic Goitside Conservation Area, was left badly damaged after the fire.

The report to the Fire Authority, which meets on Friday, says: “The cause of this fire was thought to be a faulty electrical supply.”
