Andy Golding, chief executive of OneSavings Bank, said: “We are lending prudently, with a controlled risk appetite and current application volumes are strong across our Kent Reliance and Precise Buy-to-Let and Residential brands.
“Total application levels for the Group are c.65% of pre-COVID-19 lockdown levels, as we remain cautious with the criteria offered in our more cyclical market segments.
“We continue to expect double digit underlying net loan book growth for 2020, excluding the impact of structured asset sales although we remain cognisant of the potential impact of the latest lockdown on the timing of completions and redemptions.
“We maintained our cost discipline in the third quarter and the underlying cost to income ratio for the full year is expected to be marginally higher than in the first half, due primarily to the impact of gains on structured asset sales in the first half.
Despite the current complex environment, the group has made good progress on the integration with CCFS and remains on track to deliver the synergies that were identified at the outset of the combination.”
