Your photograph does not show how unlike the original these replacements are, with or without stick-on lead. They symbolise everything that is bad in modern building materials - characterless, pastiche, less durable than the material they replace, and ultimately not even bio-degradeable: in Sweden discarded UPVC windows are classified as toxic waste.
I have had dealings with the council's historic buildings officers, and found them helpful and sympathetic. They are legally bound to enforce listed-buildings regulations, and have gone beyond the call of duty with their interest-free loan to the Greens.
As I look up from writing this, I view the village through leaded lights of wavery old glass. It is a delight that should not be denied to future generations. If I want more silence or heat retention, secondary glazing panels fitted inside will not destroy the old.
Ignorance of the law is no defence: but I wholly agree with the last sentence of your leading article - the installers are party to the offence. It is not the first time that they have skated over the listed-buildings regulations in this area, in pursuit of a quick buck, and another house loses its original 'eyes' to the world.
