Person-level resolution — identifies named residents at the address, not just an account holder.
Household composition and property classification — resolves who lives with whom, names the head of household, and confirms property type (residential or commercial).
Unbilled occupant detection — surfaces residents at properties not currently in your billing system, so revenue and entitlement gaps close.
Confidence grading + contact strategy — each match graded; guidance on how to action high, medium and low-confidence cases delivered alongside the data.
Integrated workflow tooling — confidence-rated records reach billing or revenue-protection agents the same day, accelerating speed to value.
Revenue protection
Right person, right bill, right entitlement; undercharging and overcharging both reduced.
Reduced cost-to-serve
Fewer doorstep visits, fewer returned letters, fewer dead-end collection cycles.
Compliance and vulnerability
Accurate identification is the foundation of UK GDPR data quality and of fair treatment of vulnerable customers.

Sagacity
For 20 years we have helped energy, water and telecoms operators — from Big Six and challenger energy suppliers, to leading UK water companies and major telcos — turn customer data into confident decisions
