This is called a Subject Access Request (SAR). British Gas must give you a copy of your personal data, tell you why they hold it, who they've shared it with, and how long they'll keep it — free of charge, within one calendar month.
How to contact British Gas
The most reliable route is to email your request to privacy@centrica.com. A postal address is also accepted as a fallback: The Data Protection Officer, Centrica Plc, Millstream, Maidenhead Road, Windsor, Berkshire, SL4 5GD.
Note: British Gas is part of Centrica.
What happens next
British Gas may ask you to verify your identity before responding — this is normal. Once your request (and identity, if needed) is confirmed, the one-month clock starts. If the deadline lands on a weekend or bank holiday, it rolls to the next working day.
Common questions
Is there a fee to request my data from British Gas?
No — under UK GDPR, organisations including British Gas must provide a copy of your personal data free of charge in almost all cases.
How long does British Gas have to respond?
One calendar month from the day they receive your request, or from the day your identity is confirmed if they need to verify it first.
What's the best way to contact British Gas about this?
The most reliable route is to email your request to privacy@centrica.com. A postal address is also usually accepted as a fallback.
What if British Gas doesn't respond in time?
You can complain to the Information Commissioner's Office (ICO). Right-of-access complaints made up 39% of all complaints in the ICO's Annual Report 2023/24 — more than any other category, around 15,000-15,800 in a single year.
