Remortgaging - can I overpay whilst not in deal

[MyPatronusIsABadger]

Ok, this is something I should probably already know, but I don’t so need some help.
In November next year my fixed rate period for the mortgage is up. I’ll want to switch to a better deal but unfortunately have some money due to bereavement. Can I go out of my deal and say do a lump sum overpayment in December next year without being penalised? Then go into a new deal?
Or is there another way I can overpay without being penalised?
Current mortgage is £96,000.00
Amount I’d like to overpay is £25,000.00
I already overpay by 10% each year without being penalised.
Thank you

I believe that I you're not tied into a fixed deal, then you can over pay as much as you want.

You need to check the terms of your mortgage as they're all different. The definition of a year may also vary for overpayments purposes. Ie, is it a calendar year, or is it a year from the anniversary of your mortgage starting.

Depending on what your rate is, and what penalties there are for overpaying, it might be cheaper to put the money in savings for now, and overpay when you can do it without penalty.
