The £150 will be paid after all residential mortgage applications submitted during January next year are completed.
The cashback is available across the entire residential range, including fee-free, fixed rates, trackers, discount and offset mortgages.
Chris White, chief executive at the building society, said: “We marked our 150th for our savers in 2015 with a special high-interest loyalty bond, now it’s the turn of mortgage applicants.
“The £150 cashback is the icing on our birthday cake.”
In October, Hinckley & Rugby launched new mortgage deals at 90 per cent and 95 per cent loan-to-value, available with offset savings accounts which can be operated online.
