Partnership expects to complete a medically underwritten bulk annuity deal within the next few weeks in a transaction believed to be the first of its kind.
The deal involves gathering medical information on members using a single-page questionnaire and using the information to set an aggregate price for insuring their liabilities.
The insurer said it had been offering the proposition since the start of the year, targeting schemes with between 20 and 100 pensioner members.
Director of corporate partnerships Will Hale (pictured) said: "We have been hugely encouraged. We have been working with all the major consultancy firms and have a pipeline of about 30 prospects which are at various stages from indicative quotes through to a couple which are weeks away from moving through to transaction."
The two transactions nearest completion cover approximately 90 and 40 lives respectively and Hale said the response levels to the questionnaire had been higher than expected at more than 90%.
He said that the offering was proving attractive for schemes with a membership profile that suggested a large portion would qualify for enhancements, particularly manufacturers and small retailers.
Hale added: "For larger schemes, they may look at different tranches, such as the hundred lives carrying the greatest liability for example.
"If we can secure those it could reduce the cost of doing the bulk of the scheme with a more traditional insurer which could be a more efficient approach to a total de-risking strategy."
Just Retirement is developing a similar proposition for small to medium sized schemes but had not yet taken it to market.
Director of external affairs Steve Lowe said: "We have had a very positive response from employee benefit consultants and their clients and we think there are opportunities, but it is still an immature market."
