Tenet and Age Partnership have agreed a deal on equity release, which will see the retirement specialist provide advice to Tenet's clients.
As part of the deal advisers in the network will refer clients on to Age Partnership advisers for specific equity release needs and on 'preferential terms'.
Tenet said the move followed an increasing demand for equity release, which was driven by a number of interest-only mortgages coming to an end. The adviser support group said it needed a "large specialist" which was equipped to take on the growing demand.
Equity release lending hit a quarterly record high of £571.6m in Q3 2016, according to the Equity Release Council, which said a total of £1.48bn was lent out in the first nine months of last year.
Age Partnership head of partnerships Adam Carnall said the deal was a "significant new partnership" for the firm.
He said: "During the due diligence process we worked closely with the team at Tenet to ensure that the customer journey between the two companies will be as smooth as it possibly can be."
TenetLime managing director Gemma Harle said: "We are pleased to welcome Age Partnership on board, giving our members an equity release specialist to refer to as appropriate. They will also benefit from preferential contract terms."
Tenet is also involved in talks to make further adviser firm acquisitions in-house. The news came after it produced a strong set of results in March, which showed continued growth at the company for the fourth consecutive year.
Group finance director Caroline Bradley said the group was in talks with small member firms about acquisitions that could complete as early as the next few months.
