Climate change activists chained themselves to the wrong building in the City of London after failing to realise the fossil fuel company they wanted to disrupt had moved address last year.

The group of 200 protesters instead brought chaos to the entrance of a building which houses the offices of a leading renewable energy company.

They thought they would be disrupting workers at the energy company Drax, which plans to build a new gas power station in north Yorkshire.

However, unbeknownst to them Drax moved its London headquarters to nearby Noble Street last year.

Instead bemused workers at Statkraft, a Norwegian hydropower company, which describes itself as “Europe’s largest generator of renewable energy”, were confronted with the protest.

A worker at the company told the Evening Standard: “They’re protesting against Drax, but they don’t live here anymore. I understand [the protester’s aims] but it helps if they check the facts.”
