Consolidating your ISAs into a single account makes perfect sense as your paperwork will
be simplified with a single statement and you can save money on administration charges. Each of your ISA providers will be charging you an annual administration fee, and an easy way to reduce these fees is to use fewer providers.

By using a discount broker where charges are capped, you will pay just one fee, however many ISAs you consolidate into a single account.

However, there are two things of which you should be aware. The first is that there may be transfer out or closure fees levied by your current providers, which can reduce the cost savings associated with consolidating your ISAs, sometimes to a considerable extent.

And secondly, you should check that you can hold, and trade, the full range of “ISAable” investments that you want to with any single provider that you may choose.
