From today, every property in England and Wales with four or more bedrooms must include a Home Information Pack when it is put up for sale. (The link points to an example template.) Included are documents such as a sale statement and Energy Performance Certificate.
There must be some conflict-of-interest issues in getting sellers to provide honest HIPs. Is this unnecessary and costly bureaucracy? Time will tell, especially as smaller homes will need HIPs in due course. Personally, I think buyers would be wise to gather their own information about a prospective new home before taking on that mortgage!
