And that's because there are too many people on this Septic Isle. In each of the last four years the population increased by almost 400,000 people. Net immigration accounted for well over half of this. 525,000 people arrived to settle here in 2018. This is in addition to the 77,000 British people who returned from living abroad. These were offset by 343,000 who left making the net influx 258,000 people.
Let's be (very) generous and say that one home is required for every three of the 400,000. This means 133,000 new homes are needed to cope with this growth. That figure ignores those homes needed to house those whose homes have been demolished; it ignores the fact that everybody arriving here seems to want to live in London or the South East; it ignores the fact that many new-build homes are bought as second homes and so do not count towards those necessary to house a growing population.
It is unsustainable to expect the country to accommodate an extra 400,000 people each and every year. A well known supermarket chain has just has a planning application to demolish and rebuild its existing store in my area refused. There are currently no houses on the site. But the the application was refused because it does not include any in the plans. So the store (who own the site freehold) must give over part of its land (at the expense of its business) to accomodate more homes to satisfy this ridiculous population growth.
There are not too few homes in the UK - there are far, far too many people. If there is any "austerity" (and I believe there is not - there will always be some people who are poorer than others and always will be) over population is one of the major causes.
