B&Q recently announced its decision to phase out sales of patio heaters, once its seasonal stock runs out in 2008.

They certainly get ‘efficient by nature’ recognition from us here at The Hunting Dynasty, especially because this information is culled from B&Q’s case study on the Carbon Trust website

Additionally, in August 2007, B&Q introduced buying standards on energy using products,
water using products and lighting. These aim to increase the proportion of energy
efficient products sold and to gradually phase out inefficient products. The retailer
plans to develop key performance indicators (KPIs) to monitor sales volumes of
low impact products and has set a series of targets around the introduction of
energy efficient products. These range from ensuring that all domestic washing
machines, dishwashers, electric cookers, fridges and fridge freezers will be classified as ‘A’ rated or above according to the EU energy standards by 2010 to phasing out all traditional incandescent light bulbs (40 watts and above) by 2011, providing sufficient capacity exists.
