Kensington & Chelsea Council is scrambling to replace its nearly £4m fire door contract, as it emerges its supplier was among the brands that withdrew their products from the market.
It could bring untold extra costs to the council, which is carrying out fire safety works amid scrutiny into its role in the Grenfell disaster, as the official inquiry into the fire continues.
The council is being warned this week it should prepare to spend even more on their doors.
It says it is among local authorities facing a “lack of clear direction nationally” amid uncertainty about fire door industry standards.
The fire door shortage is affecting local authorities and housing associations nationally – with many launching into multi-million pound fire safety works to high-rise blocks all at once in the Grenfell aftermath, creating sudden demand.
Kensington & Chelsea awarded a £3.6m contract to Specialist Building Products trading as Permadoor for 4,000 doors in June, on the condition that the product it was supplying passed a subsequent furnace test ordered by the council.
But the fire door manufacturer was among several to pull their products the following month.
The council is also carrying out the independent furnace tests of door types that it used for past installations, with results expected by November.
If those do not pass the council would have to factor in their replacement too, which would blow out spending to an as-yet-unknown amount, the council's report said.
“This is a matter that most local authority landlords face as on the whole the majority of suppliers have not tested their doors to the standards required by building regulations," a Kensington & Chelsea Council spokesman said.
It emerged last week Hackney Council is preparing to spend millions on new and replacement doors for about 17,000 homes while the City of London Corporation has recently begun a pilot scheme of replacing doors with products of up to 60-minute fire resistance.
The Ministry of Housing, Communities and Local Government has been contacted for comment.
