When you move house, there are a number of important places where you'll need to update your address.
First and foremost, you'll need to inform the Royal Mail of your new address. This can be done by visiting their website and filling out their change of address form. This will ensure that your mail is redirected to your new address, and that you don't miss any important letters or packages.
Next, you'll need to inform your bank and other financial institutions of your new address. This is important for a number of reasons, including ensuring that your bills and statements are sent to the correct address, and that any credit checks are accurate.
You'll also need to inform your utility providers, such as your gas and electric companies, of your new address. This will ensure that your bills are sent to the correct address and that your utilities are connected at your new home.
Additionally, you'll need to inform the DVLA (Driver and Vehicle Licensing Agency) of your new address if you have a driving licence, as your licence will need to be updated with your new address.
Finally, you'll want to inform your friends and family of your new address, so that they can send you mail and cards, and visit you at your new home.
In summary, when you move house in the UK, you should inform the Royal Mail, your bank and other financial institutions, your utility providers, the DVLA, and your friends and family of your new address to ensure everything is updated accordingly.
