The news report points out that RWE npower, with 6.6 million customers, paid no corporation tax between 2009 and 2011, while Scottish Power paid only £102m in 2012 on profits of £1.2bn — even though the lowest corporate tax rate is 20%. In general, suppliers that are owned by foreign-based multinationals paid less tax than their UK-based counterparts (Centrica or SSE).
