Campaign to cut fuel allowances for elderly in UK?

It gets bandied around often..... elderly people get free bus passes and winter fuel allowance. There are others who are suffering. Whilst that may be true, there are a great number of pensioners who rely on these things to keep them going. Perhaps the politicians and think tanks who believe these ideas should be scrapped altogether could come up means testing so that people who for example have more than one car and do not need a bus pass could give that up. Or that winter fuel allowance not paid to pensioners earning more than a certain amount per year. If they can come up with schemes to means test things such as Council Tax reductions (the application is comprehensive, intrusive and as thick as children's picture book!), they can surely come up with a more effective way of helping the elderly people who really do need these lifelines.
