“You should see what you can put away based on a new budget as the April 1 price cap will increase by 50 percent.
“So, any spare money, after you’ve built that emergency savings fund and planned for the future increase can be used to overpay your mortgage.”
Mr Lewis added: “Compared to putting money away in savings, overpaying a three percent mortgage without penalties would seem like a good thing to do because it’s a bit like saving at three percent and you can’t save at three percent.
“So yes, overpaying with spare cash.”
