The charities are also starting the final stages of the due-diligence process and have said they will also consider starting the process to appoint a new chair and board.
“Spending time and energy operating separately no longer makes sense,” said Catherine McLoughlin, chair of Age Concern England. “Instead, we intend to pool our talents and resources to ensure older people’s needs receive the even greater focus they deserve.”
Jo Connell, chair of Help the Aged, said there had “never been a greater need for such an organisation”.
“The demands of an ageing society mean that this in-principle decision – which has been taken collaboratively and in partnership – is the right one for older people today and tomorrow.”
A final decision over whether the organisations will merge will be taken in September.
