Pop Larkin, sounds like all your pensions are defined contribution or DC pots. The level of research and time to advise on this type of pension is vastly less than defined benefit pensions (DB). Unlike DB pensions over £30k, there is no statutory requirement to seek advice and if you are financially savvy, you could consolidate these yourself for no charge. However, you indicated you are not so advice would be recommended.
£5k sounds rich for this type of advice,I would suggest half that would be more reasonable.
In relation to ongoing charges, you have no obligation to take this service and you’ve got to challenge the IFA what you are getting for your 1% a year to make this value for money; roughly £250 a month is a lot for potentially a short report saying your funds are doing well 😉
