The BWF made its urgent plea in a letter to Bob Neill, parliamentary under secretary of state at the Departmentt for Communities and Local Government (DCLG).

In a joint letter to Mr Neill, BWF chief executive Iain McIlwee, and Gary Amer, chair of its Fire Door Inspection Scheme, said that the current Regulatory Reform Fire Safety Order (FSO) and Building Regulatons were "vague" and "lacked clarity" on the subject of fire doors.

"The wording of the FSO can allow overly subjective definition," they said. "Terms such as ‘so far as is reasonably practical’ and ‘where necessary’ enable building owners to find loopholes in the legislation."

There was also insufficient knowledge on fire doors among inspectors.

"A fire doorset is a performance engineeered product and it only functions properly when installed correctly with all the right components," states the letter. "Questionable decisions are made during fire risk assessments due to a lack of expertise from individual assessors."

Members of the BWF-Certifire fire door safety scheme had also reported enforcement of rules varying from area to area.

"We’re also concerned that as a result of inconsistent rulings on the FSO, some building owners could be led to believe they do not need to worrry about the state of fire doors if they have sprinklers, or other measures, in place," said the letter.

Mr McIlwee and Mr Amer said that poor fire door installation was another worry and called for installers to be covered by "competent person schemes".

"It’s at odds with common sense that, as their work is rightly considered life critical, electricians and gas engineers have to belong to a professional scheme, but anyone can fit a fire door," said Mr McIlwee.

They said they were building up "quite a dossier of cases where fire doors were no longer compliant, have been badly damaged or were not [maintained] since installation".

"This year we saw the prosecution of a Bideford hotel for malfunctioning doors, including reports from guests trapped in smoke-filled corridors because a door jammed," said the letter.

The BWF says its third-party accredited FDIS can help raise the level of expertise and competence of fire door inspectors and recommends its wider adoption.

"FSO enforcement [also] needs to be more stringent and clearer to ensure those responsible know where they stand," said Mr McIlwee and Mr Amer. "We have a right to expect we will be protected should fire break out. This is being put at risk by the lack of clear, mandatory and well-enforced fire safety regulations."
