Hi OP, we are in a similar boat, both solicitors. We are subject to taper so can't put much into pensions. We are putting additional money into GIAs, realising gains every year to use our CGT allowances then once we retire (in 4-5 years) we'll bed and ISA it over the years, again using CGT allowances (and also paying some tax).
One thing to think about is whether you'll want to make large gifts to your children- not sure how old they are but for us we're hoping to buy them each a flat in the next 5 years or so and then (depending on how our investments do) further gifts down the line. If you might want to do the same then it's worth thinking about where you would want the money to be to do this- if it's all tied up in the pension then you may end up paying 45% to get it out despite only having got 40% relief on the way in.
You've mentioned seeing an advisor or planner and that's a good idea, but you can also do some basic planning yourself just with a spreadsheet- put all your assets into it, model what might go into a GIA in the years up to retirement and how your investments might grow, then take a look at what you'll have on retirement and as you grow older and whether it's where you want it to be, then compare that to putting it into the pension. You can specifically run the numbers on your £60k which currently goes into the pension and see just how much tax you'd pay if it instead went into two GIAs (you and your husband) and you were careful about realising gains to make use of your allowances along the way, then compare that to what would happen to it inside the pension.
Another thing you could do is set up LISAs for your children but bear in mind that they only work where the property bought is under £450k so if they want to live in an expensive area LISAs may not be a good option. And of course you can put money into pensions for them- if you put in the max for non earners over 5 years that could end up at around £25k in each pot with a bit of growth, which may conceivably grow to £400k (nominal) by the time they retire even if they never put another penny in.
(Maybe not in the spirit of the board but my view is that it's very easy to over-focus on tax efficiency and end up tying yourself in a pretzel to avoid paying more tax than is absolutely necessary. There was an example on these boards not long ago- someone whose parent wanted to give them a house but couldn't face the CGT, so the child had no house, the parent had to keep paying the costs on a second home they didn't want, and the whole thing would be subject to IHT on death anyway at a higher rate than the CGT would have been. A better approach is to think first about what you actually want to do with the money in the longer term, and then consider how to do it tax efficiently. There's a lot of money knocking about so there will be tax to pay over the years and that's fine. Also PMSL at the people suggesting tax evasion!)
