Leeds Building Society and Bank of Ireland will cut interest rates on new contracts tomorrow by up to 29 basis points.
Bank of Ireland is cutting prices on its Bespoke range across most LTV levels from 75% to 90%.
For example, a two-year LTV fix of 80% drops by 29 basis points from 5.22% to 4.93%, while a five-year deal with the same LTV drops by 5 basis points to 4.65%, both with a fee of £1,495.
Both deals come with £500 cashback.
At an LTV of 85%, a two-year fix drops by 28 basis points from 5.27% to 4.99% with a fee of £1,495.
There is also a cashback of €500.
The lender is also reducing prices with 90% and 95% LTV on two- and five-year terms, with a range of different fees and cashback options.
In addition, it reduces rates on selected large loans, green mortgages and buy-to-let deals.
In Leeds, the biggest reductions are in some of the buy-to-let limited company deals, which are down by as much as 20 basis points.
It also reduces purchase rates for select homes by up to 16 basis points.
Existing deals will be withdrawn from midnight tonight.
The changes come as Suffolk and Market Harborough building societies both announced they have cut rates by up to 30 basis points today.
And Santander is going to make cuts tomorrow.
