A Subject Access Request (SAR) is your legal right under UK GDPR and the Data Protection Act 2018 to obtain a copy of all personal data an organisation holds about you. A well-drafted request gets faster, more complete responses.

Find the right person to write to

Every organisation that processes personal data must have a named contact for data protection queries — usually a Data Protection Officer (DPO). Find them in the organisation's privacy policy (usually linked in the website footer) or search the ICO's Data Protection Register. Address your request to the DPO by name or title. Do not send it to a general customer service inbox — it may never reach the right team.

What to put in the letter

State clearly: (1) that you are exercising your right of access under Article 15 of UK GDPR; (2) a description of the data you want — be specific where you can ("all emails containing my name between 1 Jan and 30 Jun 2026", "all call recordings", "my credit file"); (3) your full name, date of birth, and any account or reference number; (4) a statement that you are not consenting to any further processing. The ICO's subject access request page has a template letter you can adapt.

Keep a timestamped copy

Send by email (not post) so you have an automatic timestamp and delivery confirmation. Forward the sent email to yourself or copy it to a separate folder. The one-month clock runs from the day the organisation receives the request — email gives you clear evidence of receipt. If you must write by post, send by Royal Mail Tracked and photograph the envelope before posting.

What happens next

The organisation must respond within one calendar month. It may ask for proof of identity if it cannot identify you — this is allowed, but it must ask promptly. It cannot charge a fee unless the request is manifestly unfounded or excessive. If it extends the deadline to three months, it must tell you within the first month and explain why.

Following up

If the month passes with no substantive response, write a brief chaser citing the date of your original request and stating you will refer the matter to the ICO if you do not receive a response within 14 days. If that produces nothing, submit a complaint to the ICO. The ICO can investigate and order compliance. You can also apply to court under section 167 of the Data Protection Act 2018 for an order compelling the organisation to comply.
