Several people in this thread have asked how the manifesto proposals compare with how care funding works currently so here are my thoughts (I work in this area):
The capital floor is actually increasing, from £23,250 to £100,000, so those in residential care would actually be much better off! And by definition, those in residential care tend to be the most unwell and vulnerable. Certainly, all of my clients with mid to advanced level dementia are in care home environments as they need proper 24 hour care with specialist nursing staff, due to the risk of wandering, neglect or injuring themselves/others.
As it stands, those in nursing/care homes are expected to self-fund and eat through virtually all of their capital (down to £23,250) and all of their income in order to fund their care. Once their assets reach £23,250 the local authority may then make a contribution towards their care costs (although this won't necessarily cover all of the shortfall). As such the so-called 'dementia tax' is already in full force and has been for years.
The biggest difference in the Conservative manifesto is that the means test for non-residential, at-home care would now include property; previously the property had been excluded, irrespective of whether it was worth £100,000 or £1m. What this meant was that people sitting in £1m houses with minimal savings (usually after having gifted away capital to family and/or trusts ahead of time) were getting their at-home care paid for by the Local Authority. Essentially the Conservatives are proposing to even the playing field between those receiving at-home care and those in residential care - I've always felt that the huge discrepancy in how the means test is applied is rather unfair on those with with the highest level of needs.
Also, the concept of rolling up the cost of care against a property & this being repayable on death is NOT new - councils already offer Deferred Payment Agreements along similar lines for those who are in residential care but don't want to sell their property.
In any case, those with a primary healthcare need can apply for fully funded NHS care via NHS Continuing Healthcare, which is NOT means tested. So those who are most unwell should be exempt from a means test anyway, irrespective of the location in which their care is provided.
To be fair, the Conservatives have done a really poor job of explaining the changes so I'm not surprised that the press is being hysterical about it.
