All landlords letting business premises from tomorrow will have to pay for the cost of showing they are marketing 'green' buildings.
New EU regulations require that offices and factories that are being built, refurbished, sold or let to new tenants must carry certificates showing the energy efficiency when the lighting, heating and ventilation systems are on. Workshops and lock-ups taking up less than 50 sq m are exempt.
The Department for Communities and Local Government estimates that the certificates will cost between £250 and £500 for small premises and up to £2,000 for larger premises.
Firms will face fines of up to £5,000 if they fail to present a valid certificate at one of the trigger points.
