The introduction of controversial Home Information Packs (HIPs) is to be delayed.

In a surprising last-minute U-turn, communities secretary Ruth Kelly announced that HIPs and their core components, Energy Performance Certificates (EPCs) would now be made mandatory on 1 August.

The government has attributed the postponement, which came just 10 days before implementation, to a lack of energy assessors. Of the 2500 it said were needed, only 520 are currently fully accredited. However, many HIP providers and estate agents are doubtful that the packs will ever get the go-ahead and there are set to be at least two more rounds of consultation before the new start date.

Kelly also revealed HIPs would only apply to homes with four or more bedrooms initially. This makes up just 18% of the overall housing market. Smaller properties are to be included in a phased implementation, though no further information on this decision has been provided.

Under the original plans, all house sellers in England and Wales were required to purchase a HIP, at an estimated cost of £350 each. The packs are set to contain local authority searches and evidence of title and leasehold information as well as Energy Performance Certificates.

NICEIC said the delay should be used to broaden the requirements of HIPs, including a mandatory electrical survey. “With 40% of homes in Britain built before 1945 it is essential to have an electrical survey, especially on older properties, before exchanging contracts,” said Jim Speirs, chief executive of NICEIC Group. He added: “Their inclusion in HIPs will give homebuyers an idea of any electrical work that is required, and the estimated cost of remedial work, which they may be able to negotiate off the asking price.”
