Overview

This API provides endpoints related to Business Rates.

The Valuation Office Agency (VOA) sets the rateable value of a property. Local councils use this to calculate a business rates bill for that property.

In this API you can:

  • search for properties
  • view the summary valuations for a property
  • view the claimed properties for your organisation
  • view the claimed properties for your clients, if you are an agent
  • claim properties for your organisation
  • claim properties for your clients, if you are an agent
  • upload evidence for the property claim
  • view the detailed valuation of your properties
  • view the detailed valuation of your clients' properties, if you are an agent
  • create a Check case for one of your properties
  • create a Check case for one of your clients' properties, if you are an agent
  • upload evidence to support a Check case
  • create a Challenge case for one of your properties
