Are there public nuclear shelters in the UK?

Short answer. The UK publishes no official public shelter programme, and there is no official register or locator of public shelters ¹². In a nuclear or radiation emergency, the protective action the UK Health Security Agency describes is "sheltering": staying indoors in an ordinary building with doors and windows closed, or evacuating when instructed ¹.

Does the UK have public shelters?

No public shelter network is published by the UK government. Official guidance from the UK Health Security Agency (UKHSA) and the Cabinet Office's GOV.UK/Prepare site does not point people to designated public shelters ¹². You will not find an official map or search tool for one.

What does the UK tell people to do instead?

UKHSA describes sheltering in your own building: "Staying indoors with doors and windows closed. This provides a high degree of protection from breathing in radioactive material in the air." ¹

The other protective action is evacuation, when the authorities instruct it ¹. Which one applies depends on the situation and on the instructions given at the time. For the general reasoning behind each choice, see Shelter in place or evacuate after a nuclear emergency?.

How do I make my home a better place to shelter?

The official advice is to go indoors and close doors and windows ¹. Beyond that, the general principles of shielding and distance are explained in What is a shelter's protection factor? and How fast does nuclear fallout decay?. Keeping household supplies for a few days, as GOV.UK/Prepare recommends, lets you stay indoors without having to go out ². See UK emergency supplies.

How will I know when to shelter?

The main national warning channel is Emergency Alerts, sent to 4G and 5G phones. See UK emergency alerts.
