Top slicing

Top Slicing enables customers who have a shortfall in their required lending, to use a proportion of their earned income when the rental income for the BTL property is not sufficient to hit our standard rental cover ratio (RCR) calculation.

A full affordability assessment will be carried out as part of an application automatically to ensure that it meets our minimum top slicing requirements and that the customers have enough disposable income to cover any rental shortfall required for any requested loan.

If an application doesn't meet our top slicing requirements the standard rental cover ratio calculation will apply and the max loan available will be offered. If an application meets our top slicing requirements and the customers have available disposable income an increased loan maybe offered up to the maximum rental cover ratio amount. This amount could be lower than the requested loan but higher than the standard rental cover ratio assessment amount.

Any changes to an application would result in a reassessment and a different amount of lending could be offered, including up to the standard rental cover ratio amount.


Check if your customer qualifies for top slicing by completing our rental income calculator. If qualifying, Top Slicing option will be given on the initial results page.
