"Shocking" figures show two wards in Clapham will suffer the biggest increase in emergency response times in London, as a result of proposals to close 12 fire stations.

Clapham fire station is one of 12 fire stations threatened with closure across London as part of Boris Johnson's London Safety Plan.

The new figures from the London Fire Brigade estimate the 12 closures would add an additional 40 wards in the capital performing outside of the six minute response time target.

These 40 include two wards in Lambeth, Clapham Town and Clapham Common.

According to the London Fire Brigade, response times to emergencies will rise in Clapham Common by 2.57mins and in Clapham Town by 3.57mins if the plans are implemented.

The disclosure comes just days after part of Clapham High Street was closed due to a building fire which required six fire engines to be called to the scene.

The leader of Lambeth Council, Councillor Lib Peck, said: “These figures are shocking and show the Mayor of London’s fire station closure plans will mean it will take a lot longer for fire engines to get to emergencies.

‘Any increase in response times is unacceptable because it threatens the safety of our residents.

"I urge Boris Johnson to think again about the closure of Clapham Fire station.”

The council's cabinet member for safer and stronger communities, Coun Jack Hopkins, added: “Anyone who is concerned about the big increases in emergency response times as a result of the closure of Clapham fire station should come along to the Fire Authority’s official public meeting on Thursday, May 16, at Lambeth town hall.

"This is a vital opportunity for local people to tell Boris Johnson what they think of his proposal to close Clapham Fire station.”

A spokeswoman from the London Fire Brigade said: “The proposals currently out for public consultation seek to maintain our London-wide response targets, which as a London-wide fire brigade is how we plan the service we provide.

“The ward level data shows how varied response times are across the capital. As is the case now, over half of all London wards would, on average, continue to get a first response within the six minute target if the proposals are agreed."

The commissioner of the London Fire Brigade has predicted cuts would mean 4.7m people will be waiting longer for a fire engine.
