The lender, which offers residential mortgages, government scheme mortgages and buy-to-let, is the latest big name to join the panel after a successful start for the mortgage club.
MCI, headed by Phil Whitehouse and part of the eKeeper group, was launched in November and has already seen the likes of Nationwide, Coventry Building Society and Lloyds Banking Group join its panel.
Managing Director Phil Whitehouse said:
“It is fantastic to have NatWest on board. It is lender which has always been committed to service and support in its work with intermediaries and this is an ethos we share at MCI. I am sure our brokers will benefit greatly from having access to NatWest’s product range.
“We already understand our brokers, we have a working relationship with them and we know what business they want. This means we can tailor our offering to them and ensure greater efficiency both for our brokers and for the lenders we work with.”
Graham Felstead, head of NatWest Intermediary Solutions, added:
"We are delighted to join MCI Club's lender panel and are looking forward to doing business with its members in what promises to be a very busy 2015."
