Contracting - Worth setting up as Ltd company?

[KenJ]

Hi all and Happy New Year!

I recently started as a contractor for a large company in the Project Management field.

Currently I'm working as PAYE through the agency who I was recruited through.

Is it still worth setting up as a Ltd company?

I know new rules have been in place since last April (?) making it less tax efficient to set up a Ltd company. Is this the case or is it still worth doing?

Any help / advice much appreciated. Thanks.
