A crackdown on the selling of pubs without energy performance certificates (EPCs) is expected, following a European directive.
One year since the certificates became compulsory prior to marketing any commercial property, experts say some sellers are still waiting until sales are guaranteed before paying to have them carried out.
But from January next year, pubs could be forced to include energy ratings in any advertisements.
This is set out in the Recast of the Energy Performance of Buildings Directive document, which was discussed at the recent climate change summit in Copenhagen. The move is designed to enhance compliance with current regulations.
Andrew Whelan, managing director of EPCs for Property, said another proposal was to cut the stamp duty paid by buyers if they carried out recommendations provided with the EPC, to improve energy efficiency.
Whelan said: "Bigger companies are generally more switched on and get EPCs done before the property is put on the market. But some individuals and smaller pubcos wait until a sale is agreed."
Head of valuations at Christie+Co, Darren Bond, said: "We are seeing more people take EPCs seriously, as they understand them better that 12 months ago. But I still don't think they see them as adding value."
Under current regulations, vendors who do not provide EPCs can be fined up to £5,000. The directive requires the UK to adjust its energy policy by 31 December 2010.
EPCs cheaper than before
The cost of having an EPC drafted has fallen 25%-50%, in the year since they became mandatory, experts say. In January 2009, the price for an average pub EPC stood at £400-£500. But now some companies are quoting prices as low as £200.
