How can we help you?

We may be able to help if you are having address problems with:

  • postal deliveries
  • utility connections or billing issues
  • obtaining credit

...or if you're involved in:

  • property development
  • refurbishing or converting buildings
  • changing the use of a building, for example from commercial to residential.

What do we do?

Some of these problems may arise because Royal Mail doesn't hold a correct address. Royal Mail will only amend its database on our recommendation so changes should be directed to us in the first instance. Royal Mail is, however, solely responsible for the allocation of postcodes.

If the matter concerns an error within our database, the problem can often be fixed immediately. If the problem lies with Royal Mail's information, it can take at least a week.

Contact us to get your address fixed.

If a new name or number must be assigned to a street, premises or development, then a series of consultations must be carried out with:

  • the Metropolitan Police
  • London Fire Brigade
  • London Ambulance Service
  • Royal Mail.

This is to avoid duplication which may cause confusion and lead to possible misdirection for emergency services and delays in postal deliveries. This process often takes up to 10 weeks to complete, depending on the complexity of the development.

It is therefore advisable that the naming and numbering of new streets and buildings is applied for well in advance of their occupation to avoid delays to the provision of utilities and other services.
