If you're transferring a DB pension such as a final or average salary scheme to a DC pension, you will normally need the approval of an IFA if its value is above £30k.
Not all IFA's offer that service, not all are interested in low values and they're only supposed to approve it if it's in your best interests.
It's not just a case of them ticking a box to say yes because you want them to!
HL's website says they charge 1-2% for advice on where to invest your money. But charges for a secured pension transfer are subject to a separate structure – probably more!

The DBCBS is a grey area:
It's not a pension as such, as in it doesn't provide an income.
It grows in a defined way.
Legally it's classed as a sub class of money purchase/DC schemes.
If it's value is over £30k, you need IFA approval to transfer.
In theory a DBCBS transfer should be easier to attain than for a DB pension. But an IFA should still look at your age and compare what you're likely to get in returns from each option, amongst other things.
For example:
A transfer for a 65 year old might be approved because they're due to take it anyway with tax being an issue.
While a 55 year old might be turned down because it might be deemed the expected returns by keeping it where it is are better than transferring.
I have no experience, but personally I think around £3k is a realistic sum .
*No IFA needed for AVC transfers.
