The building society has also slashed its 5-year fixes by up to 0.30%.
Its 10-year fix comes with a £199 booking fee and £400 completion fee for new purchasers or house movers, but they can also utilise a £500 cashback offer.
Remortgage customers taking out the product pay no completion fee and receive a free first standard valuation and fees assisted legals.
David Taylor, the West Brom’s head of products, said: “We are pleased to be adding a 10-year fix to our options for borrowers, which increases choice depending on how long they want to protect themselves against a rate change for.
“We are offering a competitive rate of interest, plus incentives that help keep the overall cost of borrowing down and the flexibility to take the mortgage with you should you need to move home.
“Knowing exactly what you will be paying each month over a longer term gives peace of mind and can help with budgeting. It also saves people the time and expense of remortgaging every few years.”
On 5-year fixes West Brom has reduced rates from 3.39% to 3.09% to 75% LTV with a £199 booking fee, no completion fee, a free first standard valuation and fees assisted legals.
