As part of the agreement, advisers of Tenet Network Services have access to the lender’s solutions for wealthy clients with complex situations.

Investec specialises in mortgages for high net worth (HNW) individuals, defined as those with an income of £300,000 and typical net asset value of £3m.

Peter Izard, head of intermediary business development at Investec, said: “We have worked closely with the team at Tenet to put this agreement in place and I am delighted they have grasped this opportunity to provide their advisers with access to Investec.

“The number of high net worth individuals in the UK is growing, and we recognise that these clients have unique and often complex circumstances that require a specialist and bespoke approach.

“The addition of Investec to the Tenet panel means that appointed representatives of the network now have access to an entirely new option and this opens up new opportunities for advisers and their clients.”

Ben Wright , director of strategic development at Tenet, added: “Private bank lending offers something quite different to the traditional approach of high street lenders and we feel that the addition of Investec to our panel is a real positive for our advisers, many of whom have high net worth clients that will value Investec’s bespoke approach to lending.”
