Around 4,400 pensioners in Havering are missing out on an extra £35 a week, or £1,800 a year in benefits.

Mayor of London, Boris Johnson is urging residents to check that they are receiving all the benefits that they are entitled to as part of his Know Your Rights campaign.

He said: “As temperatures plummet many households face extra pressure on their budgets as their fuel bills increase.

“I would urge pensioners to pick up the phone and make one simple call to check that they are receiving alll the financial support they are entitled to.”

The campaign is being run in partnership with Age UK London, Citizens Advice and Carers Trust.
