Energy minister Claire Perry has had a smart meter fitted at her own home, the department for Business, Energy and Industrial Strategy (BEIS) has revealed.

In a tweet showing the minister during the installation, BEIS said: “Another smart meter installed today, this time at energy minister @claireperrymp’s house, giving her more control over her energy use. “The great switch-off experiment has already started!”

Perry’s home installation comes seven years after the rollout commenced in 2011.

The government aims to have offered every home a device by 2020.

British Gas is leading the way with smart meter installations, having supplied more than five million to customers so far.

Britain’s biggest energy supplier, which is owned by Centrica, said it has installed 5.6 million domestic smart meters and a further 590,000 in businesses across the UK.

Eon has installed 1.2 million while SSE recently installed its one millionth device.

Scottish Power says it has also installed one million while EDF and Npower have installed 750,000 and 428,000 respectively.

There have been functionality issues reported concerning the first generation (SMETS1) devices, with customers finding their meters go “dumb” after they switch supplier.

Regulator Ofgem has previously warned it will consider taking action against companies who do not accurately inform customers that their smart meter will lose smart functionality after switching supplier.
