I have just varied things rather by requesting a TFLS whilst also combining a free standing AVC in the same company's scheme as part of the TFLS. It really does pay to look in detail at scheme rules (I'd many years previously bought extra DB entitlement using the taxable portion of a redundancy payment - because I looked. Nobody else had done it previously)
When they sent me the final retirement options they had left this option off, but fortunately my IFA and I remembered it had appeared on one of the earlier quotations I had requested when I was considering the possibility of taking the pension earlier. That delayed things by several weeks.
Of course it's early days since I only requested this 3 or so weeks ago, once I had received the full numbers & options, and the Pension Administrators (the country's largest, I believe) did not have an up to date form for my situation* - something my IFA had to point out to them, so I scribbled my numbers on their form with their approval, once they'd accepted it wasn't fit for purpose in my scenario.
Oh and they didn't send me a necessary form to approve the transfer of the AVC funds across to the main account so they could be combined, so that came a week later.
This rather continues the theme of financial institutions looking shiny on the outside, but being very very variable in terms of their knowledge of their own products, and also their service to their customers.
On a brighter note, the institution which administers my SIPP has now stopped its regular data breaches when it was processing my monthly drawdown payments. Again, astonishing that one had to point out that putting identity identifiers and open financial amounts in an email was not compliant with the terms of the GDPR.
It sounds like I have it in for the industry and I guess I do, but it's based on mine & my wife's experiences of it (via 6 or 7 institutions) at a time where it's vital that everything is clear and administered correctly. OTOH when a company gets it right, it shines out like a little beacon, something I've also acknowledged in other posts.
*Lifetime Allowance was abolished before I started talking pension incl. tax free cash so it didn't apply to me, but they were insistent the it did...
