Council tax band (declared and predicted) in lending decisions.

Council tax band (declared and predicted) gives declared property council tax band where available, otherwise modelled, published modelled with 99.05% coverage across England. Where modelled, it remains separate from declared evidence so you can validate it against your own reference records. Attribution and refresh period are in the dictionary.

Pretira publishes council tax band (declared and predicted) modelled at 99.05% coverage across England, refreshed yearly, with declared and modelled kept separate.

16.1Decision rule
// routing pattern
IF council_tax_band_declared_and_predicted != application.band -> flag for verification

The rule is a pattern, not a policy - you set the operator and the cut-off to your own appetite. On the sample record this field returns "standard", the kind of value a rule like the above turns into a verification prompt or a pass.

16.2Where it bites
01

Green-lending product routing and disclosure work.

02

Portfolio concentration views by energy band and running cost.

03

Affordability context as a property running cost, never borrower profiling.

16.3Provenance

Modelled from property attributes and published separately from declared evidence so it can be evaluated against reference records. Refresh is yearly, rendered from the dictionary rather than assumed.

16.5FAQ

Three questions on this field.

A model published separately from the declared view so your rules can weight the evidence and your evaluation can compare it with reference records.

Yes, treated as an illustrative pattern rather than a policy. Pair it with your own thresholds - and, for a value, with its confidence level - so the routing rule stands on provenance, not hope.

Covered across Great Britain. Northern Ireland leads with attributes and rebuild, and this layer is GB-today - the coverage column says so rather than implying parity.
