Government and council planners are not yet tackling a looming problem of housing for Britain's ageing population - the 'last-time buyers'.

This is the verdict of the country's largest network of independent estate agents, Home Sale Network, which has 740 members throughout the country.

A massive 82 per cent of respondents to a Home Sale Network member survey say they have seen no evidence of local councils addressing the anticipated housing shortage for the growing number of elderly 'last-time buyers'.

More than half (59 per cent) of respondents said that the UK is heading for a crisis if planners do not find solutions to cope with the elderly population.

Dominic Subbiani, of Frank B. Mason and Co in Haverfordwest, said: "Throughout the sustained period of house price inflation, all the focus has been on the plight of first-time buyers and key workers. Meanwhile, we have the ticking time bomb of an ageing population of last-time buyers, who also need to find suitable and affordable homes.

"While the recent report by Kate Barker, commissioned by the Deputy Prime Minister, addressed the need to boost housing supply for the working population, there was no reference to Britain's growing population of elderly people. Our fear is that no-one, in Government or in local planning authorities, has spotted the imminent housing crisis for elderly people."

It is a fact that people are living longer. It is estimated that by 2031, there will be approximately 15 million people over pensionable age in the UK. Home Sale Network members were asked how the housing industry should accommodate the ageing population.

More than half (58 per cent) suggested that planners should insist on building more 'sheltered housing' schemes (buildings where elderly people live independently, while having access to common areas and 24-hour emergency care).

More than a third of members (37 per cent) think the Government should make it mandatory for developers to include an element of sheltered housing for the aged in all future mixed developments, alongside existing demands for affordable and social housing.

And 21 per cent of Home Sale Network members said more homes should be planned and built to Lifetime Homes Standards (a housing concept introduced in 1991 that incorporates, at the design and construction stage, the ability to make future changes easily).

Only five per cent of those questioned said that their local council is taking steps to accommodate the ageing population by insisting, for example, that retirement homes are an element of all new developments. And 13 per cent believe their local council may be talking about the issue, but has yet to begin addressing the housing needs of the elderly population in their area.
