Overpaying vs saving?


Hi, I’m not the most financially literate, so just checking my plan here with you sensible people - hope that’s ok!
I bought my first house un June, I borrowed 160,000 at an interest rate of 2.65% fixed for 5 years.
I have been putting an extra £100 a month aside, with the intention of overpaying my mortgage by this amount, once I’m sure I can afford it.
However, I have read that you should only overpay the mortgage if the interest rate is higher than a savings account.
I can get a 1-year fixed ISA with a rate of around 3%.
So, does this mean that I would be better off paying my monthly £100 extra into this savings account, and continue to do so far the next 5 years, so long as the interest rate is above 2.65%? Then, when my mortgage fix comes to an end, I use the lump sum to overpay at that point?
I hope this makes sense - does it sound sensible to you?

Aside from this, if your mortgage has early repayment charges during the fixed term and you might think about selling the house before the fixed term is up, then making use of the allowed overpayments could help you.1 -

Martin Lewis and the MSE website has always advised having 3/6 months of savings in a savings account just in case.
If your self employed or on contract working then double that.
However we have used regular saver accounts to build up funds and also over paid every month on the mortgage.
It's a habit once started.
Say you could overpay £100/200/400 a month and clear some of the mortgage debt over the next 5 years.
Would this get you into the next LTV bracket 75% or even 60% LTV ?
Most fixed rate residential mortgages allow 10% overpayments each year which is alot of overpayments but check the T and C,s of your deal.
It's a marathon not a sprint to become mortgage free.
We did it in 8.5 years rather than 22 and saved over £50,000 in interest.2 -

However a 1 year fixed ISA wouldn't be suitable for monthly deposits.
Anyway as said above why not put £100 a month into an account paying higher interest - e.g. 5% see below.
