Lifestrategy are great products, and a one stop shop as expatscot says above. If you’re ok with the bias to UK there isn’t really a need to look at anything else.
for me they’re too heavily biased to UK so I use a pure market weighted global equity tracker (cost 0.13%)
bonds are a little more complex – it’s generally advised to match your duration to your investment time frame (short, medium, long duration), and some people prefer to diversify into global government bonds (hello Liz Truss)
longer duration = more sensitivity to interest rate changes (market rates not BoE rates)
monevator does an excellent summary of the best passive investment vehicles in each asset class. Look it up
