The short answer
Official advice doesn't ask anyone to build or find a bunker. UK guidance for a radiation emergency is to get into the nearest solid building, go to the middle away from outside walls, and stay in. Being below ground helps: Ready.gov says basements, underground car parks and subways can give good shelter from fallout. But no official source we found says a home bunker would survive a nearby blast, and digging a new basement commonly needs planning permission and must meet building regulations. For most homes, a prepared inner room with 3 days of supplies is the sensible first step.
What official advice says about shelter
UK advice for a radiation emergency never mentions bunkers. UKHSA and Be Ready say:
- Go in: get indoors as soon as you can, close doors and windows, and keep away from outside walls.
- Stay in: you may need to stay in for one to two days, possibly longer.
- Tune in: follow official advice on the news and GOV.UK.
UKHSA's booklet for people near nuclear sites says staying indoors with doors and windows shut gives a high degree of protection from breathing in radioactive material and from radiation on the ground.
Ready.gov, the US government's advice for a nuclear explosion, goes further on where in a building:
- The safest buildings have brick or concrete walls.
- Basements, underground car parks and subways can give good shelter.
- Go to the basement or the middle of a large building.
- You'll usually have 10 minutes or more to get inside before fallout arrives.
So "below ground and in the middle" is good advice. That's not the same as needing a purpose-built bunker.
Can a bunker survive a nuclear blast?
Honest answer: no official UK source we found gives a figure, and we won't make one up. It would depend on the size of the weapon, how close it was, and how the shelter was built.
What we can say from official guidance:
- For most people, the danger beyond the blast area is fallout, and any solid building, especially below ground or in the middle, cuts it a lot.
- The National Risk Register 2026 says the government's nuclear attack scenario is held internally at a higher classification, so there's no public official view of where, or how large.
Are there public bunkers near me?
People search "nuclear war bunkers near me" and "ww3 bunkers near me". None of the official public guidance we checked (UKHSA, Be Ready, the National Risk Register) points the public to bunkers or public shelters. The advice is to shelter where you are, in the nearest solid building. Please don't plan to travel to a shelter during a warning: official advice is to get inside quickly.
Building a bunker or basement at home: the rules
If you're thinking about an underground room, it's treated like any other basement project. From the Planning Portal:
Planning permission - Creating a new basement "will commonly require planning permission" because of the major works involved. - Local planning rules may limit depth and size. Talk to your council before you apply. - Converting an existing basement is unlikely to need permission, unless you add a lightwell, change how the outside looks, or create a separate home.
Building regulations - These cover fire escape routes, ventilation, ceiling height, damp proofing, electrics and water supply. - Underpinning and foundation work may be needed. - If you share a wall with a neighbour, you must consider the Party Wall Act 1996.
Rules can differ by council and between the UK nations, so check with your local council before you start.
Cost: we didn't find an official or independent figure we could check, so we haven't given one. Any underground build needs a structural engineer, planning advice and building control sign-off. Be wary of anyone selling a shelter with countdowns or claims that it "guarantees" survival.
The better first step for most homes
Before spending thousands, do the things official guidance actually asks for. They cost little and help in power cuts, floods and storms too.
- Choose your shelter room: a cellar or basement if you have one; otherwise the middle of the ground floor, with the fewest outside walls and windows. See which room is safest.
- Keep 3 days of water and food there: 3 litres of water per person per day (Be Ready).
- Keep a battery or wind-up radio, a torch and a first-aid kit with it.
- Know the steps in what to do if there's a nuclear attack warning.
What to buy
About these links: plain links to ordinary retailer pages. We may earn from some links in future; we don't now. We haven’t tested these and we don’t rank them: they are examples that were in stock when we checked. Prices change. Check what you already own first. Full kit list
Battery or wind-up FM radio
Look for: FM (Be Ready asks for FM; DAB as well is fine). Both a crank and ordinary batteries, so you have two ways to power it.
Bottled water
Look for: 3 litres per person per day for 3 days, for drinking. More for babies, pets and medical devices.

Torch or head torch, plus spare batteries
Look for: Runs on the same AA or AAA batteries as your other kit, so one spare pack covers everything. A head torch leaves both hands free.

Frequently asked questions
Can bunkers survive nukes?
It depends on how close the explosion is, and no official UK source gives a figure. What official guidance does say is that being underground or in the middle of a large brick or concrete building gives good protection from fallout, which is the main danger for most people beyond the blast area.
Are there public nuclear bunkers in the UK?
None of the official public guidance we checked (UKHSA, Be Ready, the National Risk Register) points people to public bunkers. The advice is to shelter in the nearest solid building.
Do you need planning permission for a bunker?
Usually, if it means digging. The Planning Portal says creating a new basement commonly requires planning permission because of the major works involved, and local rules may limit depth and size. Converting an existing basement is unlikely to need it, unless you change the outside of the building.
Do building regulations apply to an underground room?
Yes. The Planning Portal says building regulations for basements cover fire escape routes, ventilation, ceiling height, damp proofing, wiring and water supply. If you share a wall with a neighbour, you also need to consider the Party Wall Act 1996.
How much does a bunker cost in the UK?
We didn't find an official or independent cost figure we could check, so we won't quote one. Any underground build needs a structural engineer, planning advice and building control. Get several written quotes.
Is a basement as good as a bunker?
For fallout, a basement is one of the places official guidance recommends. Ready.gov names the basement or the middle of a large building as the best place to shelter.
