Norfolk Fire Service has confirmed that a fire station which burned down on Tuesday morning wasn't fitted with sprinklers.
The retained station at Downham Market was destroyed along with a new vehicle inside. The damage has been estimated around two million pounds.
The county's deputy chief fire officer said the service should have followed its own advice.
The station currently has a new engine which is being kept at the police station, next door to the destroyed fire station.
Norfolk Fire Service investigations are continuing today into how one of its own stations caught fire, destroying the building and its new fire engine inside.
The blaze at Downham Market started in the early hours of Tuesday morning. Compressed air cylinders inside the building exploded.
The cost of the damage is expected to be around two million pounds.

An investigation has started after a blaze destroyed both a fire station and the new fire engine inside at an estimated cost of £2 million.
It happened in Downham Market at around midnight on Monday night. People living nearby had to be evacuated after breathing apparatus cylinders inside the building exploded.
Dozens of firefighters from across Norfolk and Cambridgeshire tackled the flames which had been spotted by officers working at the police station next door.
The ravaged building was only eight years old. A thorough investigation is underway but early indications are that an electrical fault was to blame.
