Address base enricher

You already hold millions of addresses, and most of them are just a line of text

Bulk enrichment of an existing address estate by UPRN with property attributes, tenure and EPC, so the book already held can be segmented first.

Most utility acquisition plans start by asking how to reach new addresses. That is a fair question, but it skips a cheaper one. The address base you already hold, from customers, prospects and past contacts, is usually a flat list: a line of text, a postcode, maybe an account status. It carries almost none of the property detail that would let you tell one address from another.

Buying more reach on top of that does not fix it. You end up targeting a bigger list that is just as thin. The instinct to grow the addressable estate is not wrong. Doing it before you understand the estate you already own is the part worth rethinking, because the answers to a lot of targeting questions are already sitting in your own file.

Enrichment turns a list into a book you can read

Matched by UPRN, each address in your estate can be attached to property attributes, tenure and EPC. The line of text becomes a property with a type, an age, an ownership tenure and an energy rating. Done in bulk across the whole file, that is the difference between a list and a book you can actually segment.

Once the attributes are attached, the questions you could not answer become straightforward. Which of my addresses are low EPC. Which are owned rather than rented. Which are the property types that suit a given proposition. None of that needs a fresh data purchase, because it is enrichment of records you already hold.

The example above is illustrative. The point is that enrichment is keyed to UPRN, so the attributes attach to the right property in your own file rather than to a postcode average.

Segment what you own before you buy what you do not

A segmented address base changes the order of the spend. Instead of buying reach and hoping it lands well, you first sort the estate you already have into the segments that matter for each campaign, then decide whether you actually need to buy more addresses to fill a gap. Often the campaign you were about to fund with fresh data can be run against your own enriched book.

The cheapest addresses to target well are the ones you already hold badly.

Keyed to UPRN throughout, the enriched base also stays clean over time, so a record enriched today can be matched against activity tomorrow without guessing which property it belonged to.

Segment the book you own before you spend on the book you do not.
