It's a little-known fact that power is supplied in the UK at an average of 242V, even though most of the electrical equipment we use is designed and manufactured to work at EU voltage levels, which are approximately 20V below the UK network.
The result is significant wastage of power and a reduced lifespan for much of the equipment in question.
PowerPerfector is a UK company that promises to cut business electricity bills through installing voltage power optimisation - a technology developed in Japan which converts a building's electricity supply to the optimum level. In doing so VPO reduces the business's electricity consumption - and carbon footprint - by up to 20%. And it provides valuable additional benefits: protecting against power spikes, suppressing 'harmonics' that can damage sensitive equipment and reducing the costs of replacing equipment earlier. The Land Registry has highlighted the protection of its electronic infrastructure and assets - which include the world's largest property database - as the most significant benefit.
