That depends on whether you’re applying together or not. If you’re looking for a joint mortgage then yes, both parties will be credit checked and any bad credit issues that come up will impact the application. It’s not the case that one partner with good credit cancels out another with bad credit - if anything it’s the other way around.
If you’re applying as a single applicant though, your partner won’t come into the equation - they won’t need a credit check just because you happen to be in a relationship with them. If you are married or in a civil partnership however then you may find it more difficult to find a lender who is prepared to consider an application from you as a single person - most prefer married couples to apply jointly.
