GreeceChecked 18 August 2026

Depends on your industryWork: HighEnforcement: Active

In one paragraph: For most businesses Greece is a normal European country: personal data can leave, as long as you use one of the standard European transfer tools. But Greece has two hard walls that Europe does not. Phone and internet connection records must physically sit on machines inside Greece. Online gambling operators must keep their records on a server inside Greece too. The privacy regulator is fully staffed and fining companies today.
The catch: The relaxed European headline stops being true the moment you touch three things. Telecoms connection records must be stored on physical media inside Greek territory for twelve months. Online gambling records must sit on a server or safe inside Greece for ten years. And Greek public bodies must run their central systems on the Greek state's own clouds, not on a commercial cloud of their choosing. Outside those three, plus the health and public sectors, Greece imposes no storage-location rule of its own.
Does this apply to me?: Yes, it reaches a foreign company with no office in Greece. The European privacy rules apply to anyone anywhere who offers goods or services to people in Greece, or who watches what they do online. The Greek national law adds that it also covers anyone processing data on Greek soil. There is no size or revenue threshold that lets you off. If you have no establishment anywhere in Europe, you must appoint a written representative inside the European Union.High confidence
Can the data leave the country?: In general, yes. Greece adds no storage-location rule of its own to the European baseline, so ordinary business data can be sent abroad once you have the right European transfer paperwork. Three industries break that rule completely. Telecoms companies must keep their connection records on machines physically inside Greece. Online gambling operators must keep their records on a server inside Greece. And Greek government bodies must run their main systems on state-operated clouds. Health, banking and insurance have extra hoops but no location rule.High confidence
What do I have to do to send it abroad?: You need one of the standard European transfer tools before data leaves Europe. The simplest is sending it to a country the European Commission has already approved. If the destination is not approved, you sign the European Commission's standard contract with the recipient, or use approved group-wide internal rules, and you write down why you think the data will still be safe there. Greece adds no extra permission, filing or fee of its own.High confidence
Who enforces this — and are they actually working?: Six bodies, and all six are genuinely working. The Hellenic Data Protection Authority is the main privacy regulator and is issuing numbered decisions and fines every month — its most recent published decisions run to July 2026 and include fines on a bank and an electricity supplier. A separate constitutional authority polices the secrecy of communications. There is also a national cybersecurity authority, a telecoms regulator, the central bank for finance and insurance, and a gambling regulator. This is not a paper regime.High confidence
How long must I keep it, and when must I delete it?: Both directions apply, and they collide. Business books must be kept five years. Medical files must be kept ten years in a private practice and twenty years everywhere else. Online gambling records must be kept ten years. Telecoms connection records must be kept exactly twelve months and then automatically deleted. In the other direction, the European rule says you must not keep personal data longer than you need it. When a specific keeping rule and the general deleting rule clash, the specific keeping rule wins.High confidence
What happens when something goes wrong?: Count three clocks, not one. If personal data is lost or exposed, you have 72 hours to tell the privacy regulator. If you run important infrastructure, you have only 24 hours to send a first warning to the national cybersecurity authority, then 72 hours for a fuller report and one month for the final one. If you are a phone or internet provider, you have 24 hours to report a personal data breach and a separate duty to tell the communications secrecy authority. Missing the 24-hour clocks is the most common failure.High confidence
What's the trap?: Five things that will cost you a weekend. First, a child in Greece can consent to an online service at fifteen, not sixteen — so an age gate built to the European default is set wrong. Second, misusing personal data is a crime here, with prison time, not just a fine. Third, several articles of the Greek privacy law are printed in the statute but the regulator has formally said they must not be applied, because they clash with European law. Fourth, telecoms connection records must physically stay in Greece. Fifth, government bodies cannot simply pick a commercial cloud.High confidence
What's about to change?: Three dated changes. Electronic invoicing between businesses became compulsory for large Greek companies on 2 March 2026 and becomes compulsory for everyone else on 1 October 2026. Greece's new artificial intelligence law took effect on 22 July 2026 and forces public bodies to register every artificial intelligence system before switching it on. And from 12 January 2027 European law bans cloud providers from charging you to move your data out.High confidence

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
