Way back in the early noughties the Government of the day introduced the Home Information Pack. This put the burden of producing LA searches, guarantees, property deeds and an energy performance certificate on the seller. A good idea in that a buyer would have at hand all the necessary information before going down an expensive path… and only required this information to be acquired once.
Sadly, in response to objections and lobbying by the real estate sector and large property owners, in 2010 this useful tool was suspended by the government of that day. Except for the energy performance certificate.
