Update: The cause of the blaze has been put down to an accidental electrical fault.

More than six crews attended the blaze which was reported shortly after 10pm on Monday, February 19.
Firefighters tackled the blaze through the night. Crews from Lincoln, Waddington, Saxilby and North Hykeham were in attendance.
The incident was scaled down in the early hours for investigators to asses the cause of the fire, which remains unclear.
