YORKSHIRE Water parent group Kelda has been named one of the UK's most responsible businesses.

The Corporate Responsibility Index highlights companies that have set up ways to measure the effect of their operations on society and the environment. Kelda Group came 86th in the top 100.

The list was headed by gas and electricity supply line operator National Grid Transco.

Others in the top 20 included BP, household products group Unilever, banking groups Co- operative Bank, Barclays and Lloyds TSB and retailers Sainsbury's, Safeway, Tesco and Marks & Spencer.

Other major names included BT, Rolls Royce, ICI and insurer Aviva.

Bradford-based Yorkshire Water was recognised for several schemes.

About a fifth of the company's workforce volunteered to take part in community initiatives last year. Yorkshire Water was also praised for its Cool Schools project to provide mains-fed water coolers in primary schools.

The company also showed how it was playing a leading role in cleaning up the environment.

The Corporate Responsibility Index was compiled by industry-led body Business in the Community, made up of 700 UK member companies.
