London: A model of Whirlpool fridge freezer has been declared safe after technical investigations ordered by British authorities because last year's deadly Grenfell Tower fire was initially thought to have started in one of the appliances.

Seventy-one people died in the blaze which engulfed the 24-storey Grenfell Tower, a social housing block, in the middle of the night last June.

In the days after the disaster, police said the blaze had started in a Hotpoint FF175BP fridge freezer, prompting the government to order detailed tests of the model, of which some 64,000 units were manufactured between 2006 and 2009.

Britain's Business Ministry and Whirlpool both said on Tuesday that the tests had established the model was safe and no recall was necessary.

"We wish to reassure consumers that these models are safe and that people may continue to use them as normal," Whirlpool spokesman Jeff Noel said in a statement.
