The summer of 2022 saw temperatures above 40°C, the highest ever recorded in England. Climate change could bring hotter, drier summers in London, with longer, more intense heatwaves.

City Hall’s Climate Adaptation team wants to hear your experience to help inform London’s first Heat Risk Delivery Plan. 

Join the conversation 

 Thinking back to the heatwave of 2022: 

  • How did you cope with the heat in London?  
  • What helped you stay cool at home or while you were out and about? 
  • What made it better, and what made it worse?  

Thinking of this summer:  

  • What, if anything, are you doing differently to cope with the heat in London? 
  • What, if anything, does London need to help you cope with the heat? 

Please share as much detail as you can. Eleanor and Annette from City Hall’s Climate Adaptation team will be reading your comments and joining in.  

About the action plan

The London Heat Risk Delivery Plan will set out the roles and responsibilities our city needs to manage heat risk. The recommendation for this action plan came out of last year’s London Climate Resilience Review.  

Between March and September 2025, Londoners and stakeholders are invited to help inform the action plan. Read more on our background page.

Going forward it MUST be addressed. The needs of citizens who don't benefit from corporate cooling ( at work for example) must be death with adequately. Some may not be able to leave their home but others like me need a space to sit and cool down and feel ok. 

 

Libraries are on the whole underfunded and it shows in their lack of ventilation or non existent AC. 

 

I did find ONE library with AC but it's in Chelsea and 1 hour journey from my home.

Somewhere to sit and read or do laptop things would be good everywhere. 

 

Coffee shops are usually well cooled but you have to spend money to be there !!!

The heatwave in 2022 was frightening. I had never experienced 40 degrees before and never want to again. My flat is south facing and severely overheats in the summer anyway and I did not know what to do. I papered over my windows as best I could to try to keep the sun from from my windows.


This summer I am struggling with the heat in my flat. I cannot get it below 28 degrees at night on hot days.

The block I live in has combustible cladding and must be remediated. I suggested that brise soleils were incorporated into the remediation design but the housing association said no. They have ‘consulted’ us about cladding materials but will not answer questions about which materials will best stop solar heat gain. Guinness housing association will not help with making my flat suitable for hot summers.


It would help if the Mayor of London would mandate housing associations to remediate their blocks to better cope with climate change and fund them to do so.


I am a shared ownership resident and live in a block, so there is nothing I can personally do to improve my flat to cope with climate change

I agree that it's a situation that housing associations must be made to consider.

Sudden temperature changes also have a big impact on health. The few public transport modes that have air-conditioning (Elizabeth line, Circle and District, Overground) are set to unreasonably low temperatures in summer. So you walk outside where there could be 30-35C and then you suddenly get into a train with 18C. That's absurd! Not only it poses a health risk but it also means electricity waste and more heat transfered into the stations or in the city. Please set aircon in public transport to a reasonable temperature such as 23C.

London should include air conditioning in new buildings by default, which help green the grid by using up excess wind and solar energy. The Mayor should come out in express support of air conditioning.

It is important to learn from other cities abroad and see how they cope with the extreme heatwaves. But one of the first things to be done would be to try and mitigate the concrete island effect and for the buidlings to be able to cool down in  the evenings, during a heatwave. It is also important to find ways to keep the green spaces green as it will help with the cooling down. shaded areas are also important along with the good airflow.

I have lived in continental Europe for years where heatwaves are very common for the last decade or so. Closing the windows in the morning after leaving them opened all night and pull the blinds off are a good solution to keep the cool air inside. However, what really help reduce the indoor building temperature is proper building insulation and external blind instead of interior blinds/curtain. Old flats can tend to trap the heat in their walls which can quickly become a vboiling room. Stricter regulation on building requirement (old and new) and government support/subventions to encourage landlords to renovate their properties can be good solutions to help renters to live in cooler flats during heatwaves.

It is vital to allow installation or air cons in flats! There is no other option for new build flats to cool down and this needs to be allowed ASAP

People die because of the extreme heat — why don't we take this as seriously as heating in the winter?

I own my home but its a block so I can't do anything to the outside or roof or install heat pumps. Freeholders need to be incentivised. There's so much roof here for solar panels

I opened windows first thing and then closed all windows and curtains about 9am.  I was anxious and it worried me when I could smell smoke.  I listened to the radio to keep myself updated about the situation in this area.

Similar to above except I now have a better fan to keep air moving.

Huge number of badly designed flats being put up which in themselves create heat problems (absorbing heat during day), no shutters or awnings (possibly not allowed) and lack of green space around flats to absorb heat. So temperatures are going up and the tower blocks are glass hot boxes, heating up all day. We have to use blackout blinds but the heat is terrible, causing misery and affecting the vulnerable - many of whom grew up in a much cooler London.

Building regs need strengthening, orientation of new builds should avoid direct sunlight, reflective surfaces can help avoid heat storage. Need concerted effort to plant and manage more shade trees. Need shaded bus shelters, better ventilation or cooling on buses and tubes and trains. Misting stations could help in central London.

Living with heat in London is difficult at the best of times but post partum with a small baby having to get buses to baby appointments which take multiple buses and having to stand with the buggy when you feel extra dehydrated from breastfeeding because there is nowhere to sit on some buses with the buggy. I've felt sick, dizzy and worried for mine and my babies safety. 

Some buses have air con but everyone opens the windows so all the cold air leaves the bus anyway. On these hot days regulating the service and leaving us all dripping in sweat isn't acceptable. Shade at bus stops needs to be an essential. 

There are many vulnerable people in society, I felt extra vulnerable for a period when pregnant and having had my baby but some people that is every summer, every year.

More free water points. Air con on all trains/buses and tubes. Designated cool areas for those who are homeless etc. more green spaces with shade. Subsidised sun cream for young and vulnerable.

Perhaps more homes should have shutters and keep outof the midday sun, if possible. Climate change will mean we have to adopt almost Mediterranean lifestyles.

There needs to be a legal limit set and enforced for the maximum (and minimum) temperature for a place of work, education setting, healthcare settings and public buildings. It is inhumane to expect people to work/learn etc in extreme temperatures.

There needs to be more shade enforced by Planning for both residential and commercial areas, including a strong emphasis on natural shade creation (eg tree planting on streets). This also needs to be brought in retrospectively and not just on new applications. The return to having small green spaces (“greens”) with shade-giving trees and bushes in residential areas.

And a return to free drinking water “refill stations” in public areas and enforce that any establishment which serves drinks to the public must give free water to anyone who asks, not just paying customers.

London needs to deal provide more street shading, retrofitting shades to public buildings particularly schools and hospitals, more public drinking water access, cooling public transport. Identify vulnerable populations in housing that overheats easily.
