Poorly insulated homes may cost £1bn extra in energy bills

Legal loophole means landlords won't need to comply with regulations aiming to protect tenants and cut carbon emissions

Tenants in the UK's draughtiest homes risk paying 1bn extra in energy bills because of a government loophole letting landlords off the hook, a charity has warned.

Landlords will be banned from letting poorly insulated homes from next April under new regulations designed to protect vulnerable tenants and cut carbon emissions.
