When we moved into our current home, it was a big, rambling wreck, and having assessed our ability to maintain it (by looking at the rateable value and making reasonable projections over our lifespan) we have injected a small fortune renovating it, using contractors initially to do the big stuff, and our own DIY efforts subsequently, when we had the skills, time and, frankly, no more money spare. There has been a lot done, with lots more to do.
Amongst other things, I am seriously looking at all the various eco-things we can do,. Now these are major capital expenses, with the benefits kicking in only after a period of many years. So it is only worth doing them if we are going to stay here... and reap the rewards.
This proposal of tying the tax to the house value in this way is therefore a double whammy environmentally. For a start I now fear for our ability to afford to live here, and certainly question any additional investment which simply raises the value and hence our ability to afford to stay here.
Is everything in this cursed country now designed to supress saving, effort and forward thinking? And all to fund the money-pit that is their parasitic, unproductive administrative systems, put in place to keep 'them' in power and clover, and rest of us under their thumbs while they concoct further ways of funding them.
Bloody, barking madness.
