The deals have rates which start at 2.85% and there are no product fees on selected products.

John Truswell, head of intermediary mortgages at Newcastle Building Society, said: “We’re pleased to be extending our current offering to 85% LTV and increasing our support across the market for first-time buyers, home movers and existing home owners looking to re-mortgage.

“We pride ourselves on our customer service and brokers can be assured their clients will receive the highest levels of service for mortgage applications and processing.”

A two-year fix at 2.85% (5.3% APRC) is available at a maximum LTV of 85% and has a product fee of £999. A 2% early repayment charge until 31 January 2022 and 1% until 31 January 2023 applies.

The newly-launched range offers a free standard valuation on properties up to £500,000 and allows 10% overpayments per annum, supporting customers who require the flexibility to make lump sum capital payments.

Alternatively, a fee-assisted two-year fix is available at 2.99% (5.2% APRC) at a maximum LTV of 85% and comes with no reservation or completion fees to pay, meaning borrowers will only have to pay associated legal costs.
