According to London Fire Brigade (LFB) between March 2014 and February 2015 firefighters were called to 525 incidents where a person was trapped in a lift.

Over the 12 months to August 2014, Tower Hamlets had 555 call outs for lifts, with Westminster close behind with 459, Camden third with 404 and Hackney fourth with 402.

However, the brigade is hoping to deter people from calling them in non-emergency situations.

On average LFB attends 13 non urgent lift call outs every day, which is nearly 5,000 incidents a year. These are calls where a person is shut in a lift but not in any immediate physical or medical danger.

LFB third officer Dave Brown said: “If there is a genuine emergency we will be there but on many occasions if you are shut in a lift it’s an inconvenience not an emergency.

“It’s the responsibility of building owners to maintain their lifts and ensure they use a lift engineer call out service if the lift breaks down.

“The brigade is always willing to work with building owners to advise on lift safety.

"Preventing people getting shut in lifts is in everyone’s interest and we’re calling on all building operators to ensure their lifts are regularly maintained and that their staff are properly trained to release people who get shut in them.”

Since 2009 the brigade has been recovering costs for non-emergency call-outs, but they are currently owed around £250,000 in unpaid charges.
