Nearly 30 care homes in Sutton are failing to meet fire safety standards, among the highest in London, audits carried out following the Grenfell Tower tragedy reveal.

Bromley tops the table with the highest number, at 71, with those homes in question either having received notices of deficiencies or an enforcement notice.

Neighbouring borough Croydon trails in second, with 44, while Waltham Forest (34), Lewisham (29) and Sutton (28) round off the top five, regional data shows.

At the other end of the scale, Hammersmith and Fulham and Merton have the fewest homes failing to meet fire safety standards, with five each.

A total of 1,226 fire safety audits have been carried out by the London Fire Brigade since June 2017, with 51 care homes having since been served with enforcement notices.

And while another 498, or 40 per cent, have received notices of deficiencies from the authorities, a large majority were found to be “broadly compliant”.

But the figures, obtained by London Assembly member Andrew Dismore from a written response, have prompted calls for care homes to get “up to scratch”.

“It is very concerning that some of the most vulnerable Londoners are being put at risk this way,” Tom Copley AM, Londonwide Assembly Member, said.

“These inspections carried out by the London Fire Brigade have been vital in highlighting, not only a local issue, but one that urgently affects the whole of our capital.

“Care homes have a duty of care to their residents,” he added. “It is vital they co-operate fully with the London Fire Brigade to get their fire safety standards up to scratch and take all possible measures to prevent any future tragedies.”

But Alison Murray, the Care Quality Commission’s head of inspections for London, has urged the care homes themselves to ensure they’re meeting the required standards.

“It’s the responsibility of those in charge of running care homes to ensure the right fire protection measures are in place in order to keep people safe,” she said.

“Where we find areas of concern we share these with the local fire service – as the enforcer of fire safety in care homes – and include [that] in our published inspection reports.

“These findings will influence whether we judge a service to be outstanding, good, requires improvement or inadequate.”

The CQC says it knows care home providers invest into fire safety training for their staff but, as the London Fire Brigade notes, “good fire safety isn’t the norm everywhere”.

She added: “I encourage all care home providers in Sutton and Bromley to make full use of these findings so they can make continual improvements that will keep everyone safe.”

Sutton Council has been contacted for comment.
