As Arvy said, I would be asking/questioning why your IFA is suggesting Abrdn. They don't pop up on any best buy tables and from what I can see they charge 0.30% on SIPPS up to £250K vs 0.15% charged by Vanguard (capped at £375).
For what it's worth, I was very happy with Vanguard but for my SIPP balance, ii will be almost half the price per year- £156 (and fixed as my investments grow).
