Views on brining old single company PEPs together

Hi, totally new to this but hoping for views on bringing old single company PEPs together. I have one with TD Waterhouse and pay no management fee (Unilever) as over £5k but would have to pay to bring other funds into this. Share Centre has two Compass and GSK, and I can bring these together for £60 pa and they'll pay for others to be brought together. Barclays PEP with Barclays, again £60pa and will pay to bring others into their, and Equiniti another £60pa has Smiths Industries. A friend has suggested that I sell these and move into a unit trust/investment trust ISA (but having bought them part of me wants to stick with them). Total around £30k, I have other investment trusts/units trust ISAs, and LLoyds TSB shares (bought at peak around 2007) outside of ISA . I am unlikely to do much trading as don't have time so do want to just leave. Many thanks for any views. Is there a better provider to move all of them to?
