Simplyhealth has plans to expand its offering with a corporate deductible-style group PMI.
The provider is currently at the review and development stage.
Howard Hughes, head of marketing at Simplyhealth, said: "I cannot speak about what form exactly it will take or when we will bring it to the market.
"It is something we are reviewing at the moment. There are no definite plans at the moment of how it will look but it is in the development stages."
Corporate-deductible pioneers WPA, said it was a hugely positive market development.
Rachel Riley, head of new business at WPA, said: "This gives the concept more credibility and it gives us more competition which is good.
"Without sounding flippant or arrogant, for this to have taken Simplyhealth two years to develop since we came to the market, it means it has looked into it properly and gives intermediaries and customers more confidence in the product."
WPA was the first to bring corporate deductible-style PMI to the market in 2010. Aviva followed suit this with a similar corporate excess offering in April.
Standard PMI insurers price corporate policies on previous claim experience, creating a claim fund, considered risk-free because the client company will likely claim up to a certain amount.
However Insurance Premium Tax (IPT) applies to the entire premium, including the claim fund.
Crporate deductible style schemes replace the claims fund with a corporate deductible account or trust, thus reducing the IPT bill and National Insurance costs.
