On the day voters head to the ballot box, HSBC said it would lower rates on its existing residential customer switching, borrowing more and residential first-time buyer (FTB) ranges.
It will also wield the axe to prices on its homemover, remortgage and international rates, coming into effect on 5 July, when the UK will find out who its new Prime Minister is.
The provider will also add a cashback incentive for residential FTB products for loan to values (LTVs) worth 60%, 70% and 80%.
Cuts will be applied across those products on mortgage terms lasting for two, three and five years.
It marks the second time since the Bank of England held the base rate that HSBC has reduced its mortgage prices.
A HSBC spokesperson said after reviewing a number of factors, it is dropping prices for its 300 mortgage rates on residential and buy-to-let (BTL) mortgage ranges.
Rival lenders have followed suit too. In its own second batch of price drops, Barclays has chopped rates down for customers on residential and BTL deals.
Existing borrowers can enjoy a five-year fixed mortgage at 60% LTV and £899 fee for 4.22%, down from 4.25%.
Santander to announce details of latest rate cuts
A two-year fix at 60% LTV with a £999 fee on its existing borrowers range has dipped to 4.67% from 4.75%, while the fee-free alternative has seen a slight cut to 4.9%.
To finance a larger proportion of your property, the 75% LTV has felt a sizeable cut from 4.96% to 4.75%, and 85% LTV rates were cut to 5.22% from 5.43%.
Meanwhile, for BTL products, the existing borrower reward two-year fix at 65% LTV with a £1,795 fee was cut by 0.2% to 4.95%. Without a fee, that option is now priced at 5.3%.
Completing the trio of providers cutting mortgage rates is Santander, which will lower selected residential purchase fixed rates by up to 0.16% on its new business range.
The lender will not amend any of its BTL, large loan, residential tracker rates or product transfer ranges.
