London & Country also worked with TSB on its pilot ahead of its residential distribution launch earlier this year.
TSB now offers its products through Sesame, Intrinsic, LSL, L&G Mortgage Club, Connells, PTFS, Mortgage Advice Bureau, Mortgage Intelligence and Tenet.
TSB last month confirmed it had been bought by Spanish bank Sabadell for £1.7bn.
TSB intermediary director Roland McCormack says:
“We’re currently piloting our buy-to-let mortgages through London & Country. The team there are offering great support in helping us iron out any creases before we roll out more widely.
“Following the success of our homebuyer and remortgage roll outs, this marks the next phase of our strategy to provide brokers with a different sort of intermediary service.
