4.2 Energy-efficient lighting

In 2019 lighting in buildings accounted for about 12% of UK electricity use. The domestic sector used approximately 14 TWh and the services sector a further 23 TWh, of which a third was used in retail premises. Put another way, we use about half as much electricity lighting our shops as we do our homes!

As shown earlier in Figure SGB.39, the promotion of low energy lighting has produced a dramatic reduction in domestic electricity use for this application.
