If you are after an ‘Income’ off £60k that won’t get you far these days, unless you are lucky to have nailed some cheap Bitcoin early on or invest in a startup business etc. But extremely high risk and personally I would not for Bitcoin…
I too haven’t bothered with NS&I as the returns have been poor such a premium bonds.
Agreed on paying off your mortgage first unless you have a cracking guaranteed rate of interest elsewhere, also future proofs you from stress if you are to lose your job etc. Buying a holiday home in the right area is also a potential option and can offer a high return over time…
Woodland and Farmland are also highly tax efficient, potential income available from grants + rewilding/tree planting + land rental. Also if you are lucky to get planning permission on a plot, that is a winner. Also the capital will grow for land….
Buying classic cars is also a good bet if you get the right one(s), more modern Maseratis I have lost a ton on but these were never an investment.
Using your maximum allowance each year for pension contributions is also a good option too (currently £40k or up to 100% of your income), at least you get tax relief which is far higher than the low bank interest rates currently offered….
