. You do an amazing job of highlighting the issues tenants face. My brother worked for a company subcontracting to keepmoat. He hated it. It was disorganised, poorly run, rubbish rates and a general shower of shite according to him. They were also rubbish at paying subcontractors which meant his bosses company eventually almost went bankrupt waiting for wages to go in.
He is a plasterer/renderer and fitted the insulation boards to the outside of properties. Some of it is similar to the Grenfell tower cladding but he only did houses not tower blocks. It will be interesting to see what happens with the legislation on these boards and the consequences.
Also I lived in a private rented property that was on a street deemed to be in need of environmental insulation. It's a 1900s terrace. To preserve the look of the street and retain the brickwork exteriors they applied insulation cladding to the external walls on the backs of the property but applied the cladding internally. Then skimmed it.
We chose not to have it done as we knew we were moving soon. Our landlord didnt push us even though it was free as he didn't like the look of it all either. Most of the rest of the street had it done and it was chaos for months. Scaffold up for weeks on end, render splattered across cars and windows, materials blowing around.
We phoned them out 3 times. They knocked the guttering off the back of our house, blocked the outside drain with debris and render all over our decking. And we didnt even have any work done.
