Mardy retailers don't usually own their premises. They lease them from landlords. But in any case, whoever owned the premises might find it made more economic sense to board them up than to install more energy-saving requirements than those that already exist on top of other costs in an economic downturn.
Alternatively landlords could put up rents to tenants and force them out of business.
That's why there are quite a lot of boarded-up shops already. Shall we add to them?
That's not because retailers want to destroy the planet. It's because they'd like to make it to the end of their lives with a few quid in their pockets to pay their funeral expenses.
Anyway, let's say after boarding up the High Street someone from the council came along to your house with a list of current Government-sanctioned energy-saving requirements including insulation to walls, doors, windows and the roof.
I can assure you that your house will be haemorrhaging energy unless you've moved into a complete new-build or have done renovations according to the strict building renovations which have been in force for some time. In some cases you may be breaking the law and that ought to be disclosed by a surveyor when you come to sell your house.
Could you afford it? Where shall we start? With landlords/retailers who'll lose their businesses and the jobs of the people they employ or you, who might lose a sale or your home?
Shall we then move on to an inventory of all the people who've lost their jobs and still live in energy-leaking houses?
These things do need to be done but in time and certainly not in the middle of a recession.
