The lender said it was making the changes, which go live on 12 May, following a comprehensive review of its portfolio, with the aim to provide more competitive options in the market.
The new deals include two- and three-year fixed rate options, with the two-year fix at 80 per cent LTV with no fee available at 2.04 per cent.
It has also cut the fee on two products, a two-year 60 per cent LTV at 1.29 per cent and a 75 per cent LTV two-year fix at 1.44 per cent, from £1,299 to £999.
Richard Scott, head of intermediaries at the West Brom, said: “We recognise that in these unprecedented times, product availability has reduced in recent weeks.
“The introduction of our new range will hopefully provide more choice for people who are coming to the end of their current mortgage deal.”
