The offer, available exclusively to brokers, was due to end Wednesday at 8pm but the extension means first-time buyers and home movers can benefit from the deal until 8pm on Tuesday 10 November.

Jeremy Duncombe, director of intermediary distribution at Accord Mortgages, said: “Since launching on Monday morning, we’ve seen the positive impact our increased capacity has had on service levels.

“The recent changes we made to LTI caps, as well as having a boosted underwriting team means we are ahead of where we planned to be and so have made the decision to extend the offering for longer. We hope advisers can support more clients get the homes they want.”

A five-year fixed rate at 3.79% at 90% LTV with £995 product fee and free valuation. Available for loans up to £500,000.
