United KingdomChecked 18 August 2026
Yes, with paperworkWork: HighEnforcement: Active
In one paragraph
Data can leave the United Kingdom, but you need the right paperwork first. Sending it to Europe or to about fifteen other approved places needs nothing extra. Anywhere else needs a government-published contract and a risk check. No general law forces data to stay in Britain. The privacy regulator is busy and its fines are getting bigger.
The catch
The easy headline stops being true in three places. Telecoms operators must keep backup copies of key network information inside the United Kingdom. National Health Service patient records may only be sent to countries the United Kingdom has formally approved, which rules out the standard contract route. And government material classified SECRET or above cannot sit in public cloud at all. Everyone else can store data abroad with the right contract in place.
Does this apply to me?
Yes. British privacy law reaches a company anywhere in the world if it deliberately offers goods or services to people in the United Kingdom, or watches what they do online. There is no size or revenue floor to hide under. If you are caught and have no British office, you generally have to name a representative in the United Kingdom, unless you are a public body or your processing is rare and low risk.High confidence
Can the data leave the country?
Yes, with paperwork. The United Kingdom has no general law forcing data to stay in the country. Send it to the European Economic Area or another approved country and you need nothing extra; send it anywhere else and you need an approved contract plus a written risk assessment. Three industries are stricter: telecoms, the health service and classified government work. Banking, payments, insurance, securities, education, online gambling and mapping have no location rule that we could find.High confidence
What do I have to do to send it abroad?
The model is an approved-list one. If the destination is on the government's approved list you may send data with no extra paperwork. If it is not, you must sign the government's own contract template and run a risk assessment first. The list is well populated: the whole European Economic Area plus Andorra, Argentina, the Faroe Islands, Gibraltar, Guernsey, the Isle of Man, Israel, Jersey, New Zealand, South Korea, Switzerland and Uruguay, with partial cover for Canada, Japan and the United States.High confidence
Who enforces this — and are they actually working?
The Information Commissioner's Office, and it is very much working. It fined Capita fourteen million pounds (about $18 million) in October 2025, Reddit £14.47 million (about $18.5 million) in February 2026, and the owner of Imgur in the same month, and it issues smaller marketing fines almost monthly. Watch a quirk: a replacement body called the Information Commission legally exists but had no staff and did no work in its first financial year, so the old office is still the one that acts.High confidence
How long must I keep it, and when must I delete it?
There is no single deletion deadline. The rule is that you keep personal data only as long as you actually need it, and you must be able to explain the period you chose. Pulling the other way are minimum keeping periods: company and tax records for six years, telecoms connection records for up to twelve months if the government serves a notice, and telecoms security data for thirteen months. Where a minimum and a maximum clash, the legal duty to keep wins and you keep the data.High confidence
What happens when something goes wrong?
Count at least three clocks. Any organisation has 72 hours to tell the privacy regulator about a personal data breach, and must tell the affected people if the risk to them is high. Telecoms and internet providers also have 72 hours under the electronic communications rules — that used to be 24 hours and quietly changed on 20 August 2025. Operators of essential services such as water, energy and transport have their own 72-hour clock to their own regulator.High confidence
What's the trap?
Five. (1) A child can consent at 13 here, not 16 — but the children's design code covers everyone under 18, and the regulator fined Reddit £14.47 million (about $18.5 million) for weak age checks. (2) Telecoms firms must keep some backup data physically in Britain. (3) Health service data can only go to approved countries, so the standard contract does not help you. (4) Misusing personal data can be a crime, not just a fine. (5) The government can secretly order a company to weaken its security, and Apple is fighting one of those orders right now.Medium confidence
What's about to change?
Two things to watch in the next twelve months. A cyber security bill is going through Parliament and will widen incident reporting to data centres and managed service suppliers — it is not law yet, so do not plan as if it were. And the privacy regulator is due to be replaced by a new body called the Information Commission, but only once ministers lay the paperwork, which had not happened by mid-2026. The regulator is also writing a statutory code on artificial intelligence.High confidence

HungaryChecked 18 August 2026
Yes, with paperworkWork: HighEnforcement: Active
In one paragraph
Hungary has no general rule that data must stay in the country. It runs on the European rulebook: you may send data abroad if you have the right legal paperwork in place. Hungary used to force state registers to be processed on Hungarian soil, but that rule was scrapped in April 2024. The privacy regulator is real, staffed and issuing decisions, though its fines are small by European standards.
The catch
Two things break the easy answer. Since January 2025 a large slice of the economy — energy, transport, banking, health, water, digital infrastructure, waste, manufacturing and most of the public sector — may only use a shared cloud or process data outside Hungary after completing a formal data classification under the cybersecurity law. And an online casino serving Hungarian players must keep its game server inside the European Economic Area, full stop.
Does this apply to me?
Yes. A company with no office in Hungary is still caught if it offers goods or services to people in Hungary or watches their behaviour, because the European privacy rules reach outside Europe. There is no revenue or headcount threshold to hide under. If you have no establishment anywhere in Europe you must appoint a written representative inside Europe, and Hungary is a perfectly ordinary place to put one.High confidence
Can the data leave the country?
Yes, on the normal European terms — nothing in general Hungarian law says data must be stored in Hungary. This is a change worth noticing: the rule that state registers could only be processed on Hungarian soil was repealed with effect from 1 April 2024, and the law that replaced it has no territorial restriction at all. Two sectors override this. An online casino must keep its game server inside the European Economic Area. And any company or public body inside the scope of Hungary's cybersecurity law must finish a formal data classification before it uses a shared cloud service or processes data abroad.Medium confidence
What do I have to do to send it abroad?
You need a European transfer tool before the data leaves, and Hungary adds no extra permit, filing or fee on top. The model is an approved-list one: you may send data to a country the European Commission has declared safe, or you sign the standard European contract clauses and write down a risk assessment of the destination. There is no Hungarian government sign-off, and no Hungarian list of banned countries. For police, security and other work outside the European privacy rules, Hungary's own Info Act sets the conditions instead.High confidence
Who enforces this — and are they actually working?
The National Authority for Data Protection and Freedom of Information, known by its Hungarian initials NAIH, and it is genuinely working. It has published decisions right through to May 2026, released its report on 2025 activity on 30 March 2026, and issued public statements in July and August 2026. Its president is Dr Attila Peterfalvi. The catch is size, not activity: a typical fine is small — two million forint, roughly six thousand dollars, in an April 2025 data-security case.High confidence
How long must I keep it, and when must I delete it?
Hungary pushes hard in both directions. The floor is long: accounting records and vouchers must be kept for eight years, and health records for decades — the health data law works in periods of thirty years and more. The ceiling is the European rule that you delete personal data once the purpose is spent. When the two collide, the specific statutory keep-period wins, so a deletion request does not empty your ledgers or a hospital's files.Medium confidence
What happens when something goes wrong?
Count at least two clocks, and three if you are a bank. A personal data breach goes to the privacy regulator within 72 hours. A cyber incident at a company or public body covered by the cybersecurity law goes to the national incident response centre, and the European rules that Hungary is copying use a 24-hour first alert followed by a fuller report at 72 hours. Financial firms have a separate and faster set of deadlines under the European operational resilience rules.Medium confidence
What's the trap?
Five things that are not in the summary. One: mishandling personal data is a crime in Hungary, not just a fine — up to one year in prison, two years for sensitive data, three years for public officials. Two: the old rule forcing state data to stay in Hungary is dead, so quoting it makes you look out of date, while the new cybersecurity classification gate is very much alive and most checklists miss it. Three: several cybersecurity deadlines have already passed, so newly in-scope companies are late on day one. Four: an online casino's game server must sit in the European Economic Area. Five: Hungary's freedom-of-information regime can make your contract with a state body public.High confidence
What's about to change?
Three dated items. The Court of Justice will rule on Hungary's sovereignty protection law; the court's adviser said on 12 February 2026 that it breaks European law, and the judgment could land any time. From 12 January 2027 cloud providers across Europe, Hungary included, must charge nothing to move your data out. And Hungary's cybersecurity supervision moves from paperwork to inspections now that the first audit deadline of 30 June 2026 has passed.Medium confidence
