What do you need reviewed ?
Presumably you are being paid at least the statutory minimum redundancy and maybe something extra.
The calculation of the statutory min is available on various websites if you need to check it, or you can post details here. if you are not being paid the correct statutory there is a route to follow that does not require a solicitor.
The extra if any, has generally no legal basis ( subject maybe to precedence with your company, of which a solicitor will have no knowledge).
