YORKSHIRE has Britain's best tap water - and that's official.

A survey out today by the Drinking Water Inspectorate rate the White Rose county as the Best of British.

The survey by the independent water quality watchdog reveals that Yorkshire Water - which last year became the first water company to trademark tap water - scored 99.97% out of 100 for its water quality.

It meant the company rated highest of all the major water and sewerage companies, with the national average standing at 99.94%.

Yorkshire Water insist significant investment in the region's water mains has helped boost the quality of water reaching customers' taps.

Yorkshire Water's water business unit director Richard Flint said: "It's very pleasing to be top of the big water companies when it comes to drinking water quality.

"We know we have a very good product in Yorkshire and one that gives bottled water a run for its money for both quality and price.

"Over the last decade we have invested heavily in making improvements to our water supply network and will be spending £157m over the next five years upgrading 2,000km of water mains."
