New Build Address Not Recognised? What to Do About Your Postcode

A new home can exist before every company recognises its address. Here is what to check if your postcode is missing from broadband, insurance or delivery systems.

You have a completion date and know your plot number, but online services still say your new address does not exist. This can happen while different address databases catch up with a new development.

What can a missing address affect?

  • Broadband orders

  • Home insurance

  • Energy and water accounts

  • Furniture deliveries

  • Banking and credit checks

  • Moving services

Plot number vs postal address

The developer may refer to your home by a plot number during construction. Ask for the full postal address, postcode and house number or name before completion.

Check broadband early

Broadband can be particularly awkward when an address has not reached every provider's database. Our new build broadband guide explains what to check before moving day.

Use handover to confirm the basics

Photograph meter readings and make sure utility providers receive the correct postal address rather than only the development plot number. Use our handover checklist so these details are not missed.

The bottom line

A missing postcode is often a database issue rather than a problem with the home itself. Start checking important services before completion so you have time to resolve any gaps.
