Hyde Park will be among the eight parks to introduce the 20p charge in 2013.
Some of London’s most popular parks are proposing to have a charge for using the public toilets to cover a shortfall in funding.
20p charge will be paid in the public spaces which will include parks like Hyde Park, Regent’s Park, Richmond Park and Kensington Gardens.
An organisation that look after the parks say its government grant has decreased by about £11m over the past 10 years.
But said that the Playground and disabled toilets would remain free.
‘Modest charge’
Is what the organisation said: “The introduction of this charge does not mean we will be making profit”
“The choice was to either close the toilets or maintain them through the introduction of a modest charge.”
The Organisation who looks after the parks has received £28.08m in government funding in 2003-4 but only £16.6m for the period 2012 to 2013.
In 2010-11 the organisation spent about £1.1m in cleaning the toilets.
There are 29 toilet blocks across the eight Parks used by an estimated eight million people each year.
The spokesman added: “We are currently tendering for a supplier to refurbish, maintain and clean the toilets, and work with us to improve them where possible.”
He said the charge would be phased in from March 2013.
