Cornwall Council has a duty to name streets and number properties. It also offers a property naming consultation and notification service.
To change or register an address, you will need to submit
- an application form
- a detailed plan
- the appropriate fee
- in some cases you may need to provide supporting documentation and/or permissions
The process takes 5 to 10 working days from the date we receive your completed application and payment made.
Please note that due to a recent system upgrade, Royal Mail are currently taking longer than usual to issue postcodes and make changes to their address database. As a result of this the completion of your application may take longer than 10 working days.
As part of the process we will also notify:
- Royal Mail
- Land Registry
- Valuation Office
- Emergency Services
- NHS
- Electoral Roll
- our internal and external services such as refuse, recycling and council tax
Some services, including some Council services, may charge a fee to update their records. Cornwall Council are not responsible for covering these extra costs.
