Royal Mail's database of properties under construction

100,000 new homes are completed in the UK every year, but until the new homeowners have moved in, the addresses do not feature on Royal Mail's Postcode Address File (PAF). The Not Yet Built database closes this data gap by listing the addresses of 500,000 properties that are under construction or in the planning stages.

This means new build addresses can be validated and verified, even if the new owners are yet to move in.

Add an additional 500,000 properties that are under construction to Royal Mail's PAF Dataset with Not Yet Built

Access to the Not Yet Built database is vital to ensure utility providers, retail companies, insurance and financial services can capture accurate addresses. With Not Yet Built data, you can discover exactly where your future customers are going to live and work.
