Infinity is funding its mortgages through a financing deal with Investec, the specialist banking group listed on both the London and South African stock exchanges.

The deal is Investec’s first venture into the UK’s non-conforming mortgage market.

Matt Gilmour, chief executive of Infinity, said: “We have achieved exactly what we set out to do. We are the only privately-owned independent mortgage lender in the market which gives us the full flexibility to react to market changes quickly.”

Under the funding deal, Infinity Mortgages retains all customer contact for the duration of the mortgage. Previously, Infinity’s mortgages were funded by Mortgages plc.
