James Hay will release two SIPPS in Q1 next year to meet the needs of both sophisticated clients and those with more basic requirements.
The provider is still working on final costs and other details for the two new products.
However, one will be a "top of the range" product providing access to "all investments permitted by HMRC".
The other new product will be a low cost, web-based SIPP with a more basic investment range.
James Hay's parent IFG says all integration plans for the company are ahead of or on schedule after its acquisition in March.
Meanwhile, IPS Partnership, IFG's other SIPP business, drew in 824 new pensions between January and October 2010.
