Greater London Authority’s (GLA) Launch of Cool Spaces Phase 2 – Outdoors - 1st June 2021 and Indoors 21st June 2021 to 15th September 2021, subject to the Government’s Roadmap out of COVID-19 Lockdown Measures

Following the GLA’s invitation to register indoor and outdoor cool spaces for opening this summer, the GLA would like firstly to thank those who have registered spaces by completing the invitation as part of phase 2.  

Phase 2 will run from 1st June 2021, for outdoor cool spaces and 21st June 2021 for indoor cool spaces, until 15 September 2021, the period when Public Health England and the NHS Heatwave Plan is in operation.

Secondly, we are pleased to let you know that, despite the significant pressures that boroughs, community groups, cultural venues and faith based communities are facing due to the impacts of COVID-19, the GLA received a positive response  with a total of around 300 indoor and outdoor sites registered to date.

 The GLA has now reviewed the cool spaces data sent by the boroughs, community groups, cultural venues and faith-based communities alongside data and mapping that the GLA holds. This ensures that the identified spaces fit into one of the three tiers that can apply to indoor and outdoor spaces: -


  • Tier 1 has the greatest number of minimum amenities that Londoners can expect from a cool space
  • Tier 2 has the second greatest number of minimum amenities
  • Tier 3 includes outdoor green and blue spaces which, although not providing the minimum amenities for tiers 1 and 2, provide suitable conditions for the public to access shade from heat.


The tiered approach to classifying cool spaces is meant to provide Londoners with a better understanding of what can be expected from spaces and how certain spaces can better fit their needs.

These cool spaces will be available to the public through an online map, which can be accessed on the GLA website. The map has a mobile function which allows members of the public to find suitable cools spaces near them.

The cool space sites are targeted at Londoners who would like to to/need to access outdoor, green shaded spaces and indoor cool spaces during the day to provide respite from the heat. This should help Londoners to better prepare for, respond to and recover from hotter summers ahead.

The cool spaces initiative isn’t targeted at ‘vulnerable’ and/or ‘at risk’ groups. Public Health England’s Heat Health Watch communications sets out the advice for these groups and is disseminated to boroughs. Also, the use of public spaces should follow current guidance on COVID-19 measures for indoors and outdoors.

The Cool Spaces phase 2 map can be found on the GLA’s website, here.

Cool Spaces

The map is of cool and shaded places of refuge for Londoners when temperatures are excessively high.

London is prone to overheating due to a changing climate and the ‘Urban Heat Island’, where temperatures can be up to 10c higher than surrounding areas. This is due to human activity like transport and urban surfaces including roads and pavements.

Cool spaces are areas where Londoners can take respite on hot days. Outdoor cool spaces are available from 1 June 2021. Indoor Cool Spaces will be available from 21 June 2021 (inline with Government guidance on the easing of social distancing). When using London’s parks and green spaces, please remember to follow guidelines on social distancing. Read the Mayor’s guidance on keeping cool on hot days.
