Abbey National will refund cancellation fees up to £25 if customers switch their mortgage and home insurance to the bank.
The company said: "If customers switch their mortgage to Abbey National, and choose Peace of Mind home insurance (either buildings, contents or both), they will be refunded any cancellation fee charged by an existing insurer, up to £25."
Abbey National's combined buildings and contents cover is available at an average of £7 per week and can be bought by anyone, not just Abbey National mortgage customers.
