The charity I used to work for had case workers who visited the client regarding the funding of the project. They needed to see everything regarding savings and income. If you had more than £6k in savings, you had to contribute towards the project, whether it was a stairlift, a wet room or a whole building extension. Surprisingly enough you wont know how many benevolent funds there are out there just waiting for someone to apply for support. The caseworkers would find out where you and your husbands careers paths had taken you and then approach the benevolent fund on your behalf. If you or your husband have spent one day in the armed forces, then SSAFA or the British legion will definitley contribute. Whatever you do dont approach a stairlift company directly, find yourself a local home improvement agency to do it for you. They will be better equipped to deal with salesmen.
.... as to getting rid of them, the best example I can remember is when a local lady had one installed by one of the best known installers. It was for her husband who had just gone into hospital, she was getting prepared for his return. The lift cost approx £12k ... sadly he didn't return. The stairlift company would not return to remove the unused lift. She said they could have it for nothing, but they weren't interested... I went along and removed it for nothing and just put it on the local tip.
