    How do I change my email address?

    • Answer
    • To change your email address with British Gas, log in to your online account, go to ‘Manage personal details’, update your email, and save the changes. It’s quick and easy to do online.

      🔑 Why your email address matters

      Billing alerts and payment reminders
      Service updates and appointment confirmations
      Security notifications and password resets
      Accessing your online account and app

      If your email is out of date, you might miss important messages or struggle to log in. That’s why it’s a good idea to update it as soon as you switch to a new one.

      🧭 Step-by-step: How to change your email address

      You can change your email address in just a few minutes using the British Gas website. Here’s how:

      1️⃣ Log in to your British Gas online account
      www.britishgas.co.uk → Click ‘Log in’
      Enter your current email address and password
      Use ‘Forgotten your login details?’ if needed
      2️⃣ Go to ‘Manage personal details’
      Find it on the left-hand side of your account dashboard
      3️⃣ Enter your new email address
      Type your new email and confirm it
      Double-check for typos
      4️⃣ Save your changes
      Click ‘Save all changes’
      You’ll see a confirmation message
      📝 Tip: Next time you log in, use your new email address instead of the old one.

      ❓ What if I can’t log in?

      If you can’t access your online account, you can still update your email by contacting British Gas directly:

      📞 Call: 0333 202 9802 (Mon–Fri, 9am–5pm)
      💬 Live chat via the Help & Support page
      📱 Message on X or Facebook

      📱 Can I change my email in the British Gas app?

      Open the app and log in
      Tap the menu icon (☰)
      Select ‘Account settings’ → ‘Email address’
      Enter your new email and save

      🔁 What happens after I change it?

      All future emails go to your new address
      Your login email changes too
      You’ll get a confirmation email

      If you don’t see the confirmation, check your spam or junk folder.

      🧪 How to check your change worked

      Log out of your account
      Go to www.britishgas.co.uk
      Try logging in with your new email

      🛡️ Stay safe: Protect your account

      Use a strong password with letters, numbers, and symbols
      Avoid reusing passwords from other accounts
      Enable two-factor authentication if available
      Keep your contact details up to date

      British Gas will never ask for your password or bank details by email. Report suspicious messages to phishing@centrica.com.

      🧓 What if I manage someone else’s account?

      If you help a family member or friend, you can update their email if you’re authorised. You’ll need:

      Their account number
      Their postcode
      Permission to act on their behalf

      Call or use live chat. You may be asked for proof such as Power of Attorney.

      🧾 What if I have more than one account?

      Updating your email in one account won’t update others. You’ll need to:

      Log in to each account separately
      Repeat the update steps
      Or contact British Gas to link accounts

      🔄 Can I go back to my old email?

      Yes. Just follow the same steps. You’ll need access to the old inbox to confirm the change.

      ✅ Quick checklist:
      Log in → Manage personal details → Enter new email → Save → Use new email to log in → Contact support if needed
