Save until you have 6 months expenditure in an ‘emergency pot’. This is how much is usually recommended to keep you afloat should something go wrong. Best to have it in something cash/instant access.
What is more important is protection for your mortgage and your income should you become ill. You may have those through work. You can take these out privately which is usually not expensive at your age or take out additional policies to top up anything your employer provides. Bear these benefits in mind if you move jobs.
In terms of paying overpaying a mortgage,
there are usually limits on how much you can overpay in a year but it is usually the case that you can cancel the overpayment at anytime. If you used your emergency pot, you could stop the payments temporarily to top it back up.
Making additional pension payments has a similar benefits to over paying your mortgage in that paying in more now makes you much much better off in future. This is because of the investment growth in the long term.
Other things to consider are that you may receive lump sums in the future, inheritance or lump sums from your pension which can be used to pay off lumps from your mortgage. Money paid into your pension isn’t accessible until your 60’s, whereas you could always remortgage to access some of your mortgage overpayments if you need to.
Also, interest rates may decrease over the next few years whereas the tax relief on pension contributions is 20 or 40% which is high. In some cases your employer will match some of the additional contribution you make.
Also, ask if your employer has free financial advice available. It may also be prudent to check what type of pension you have and if it is invested the best way for you. People often forget this and put money in and don’t understand how it’s actually invested ie low risk/high risk.
Generally - the rule of thumb for priority is…
- emergency pot/cash (6months)
- protection
- mortgage
and/or pension (maybe pay 50/50 from what’s left of your £1000).
Make sure you have a Will in place and update any letter of wishes for pensions and life insurance with your employer.
Review your plan in few years or if something major changes in your life.
