One energy supplier has been criticised for its tactic of sending eco-friendly lightbulbs to its customers.
The firm, Npower, took the action ahead of a government ban on energy suppliers sending out bulbs as part of their energy reduction efforts.
Energy suppliers in the UK were set a range of obligations by the government to reduce their impact on the environment. Firms have worked to encourage homeowners to carry out various energy saving projects, such as installing cavity wall insulation.
But, according to the Times, Npower opted for a cheaper option to cavity wall insulation and sent out low energy lightbulbs to its customers. Such a method had been used previously by other firms, but the government introduced a ban on this as it was unclear whether the bulbs were actually being used.
The newspaper adds that the company had initially focussed on home insulation, but when figures showed it was going to fall short of its targets, it switched to mailing out lightbulbs before the government ban came into force.
