CONTROVERSIAL Home Information Packs - piloted in Huddersfield - have been delayed for two months.
Communities Secretary Ruth Kelly confirmed the postponement of the full-scale introduction of the packs, known as Hips.
She told the Commons the launch date would be put back to August 1 for a phased introduction.
The postponement follows pressure from opposition MPs and the launching of a legal challenge by the Royal Institution of Chartered Surveyors.
Ms Kelly said Hips and Energy Performance Certificates (EPCs) would initially apply to four-bedroom properties and larger.
They would be introduced for smaller homes as soon as possible.
Also, the number of energy assessors has fallen short. The Government had said it needed around 2,000 by June. At present there are 520.
However, the delay and watering down of Hips has disappointed environmentalists and also failed to pacify the property industry.
Green groups said the move was bad news for the fight against climate change.
