Few reasons, mostly because home ownership is fetishised in the UK to an absurdity and doing so could quite possibly curb property values. Previous conservative governments bribed practically an entire social class by giving away social housing at way below market value. There is a massive amount of people in that generation who are wealthy simply because of that policy combined with large rise in house prices. This selection of people + regular homeowners no matter the party line, will always vote against any policy that a) has the possibility to curb increasing house prices or b) fairly taxing those profits. We don't have anything like property taxes in the UK, and the closest thing we do have is council tax which (laughably) is the tenants responsibility. It's a situation that no party has a realistic chance of being able to solve. Even if there were MPs brave enough, it's a difficult problem to navigate because there's millions of people with 0 savings (retirement or otherwise) but now own 500,000gbp+ houses. If you tax that appreciation in value or your policies reduce these prices to sustainable levels then you suddenly have to now provide social security for millions of people who now will need a lot of extra assistance via state pension.
