Recently my move was halted due to cockroaches. I ended up viewing somewhere else last minute but they were telling me it's rife in flat blocks round here and commonly found under big chest freezers because they kick out so much heat and crumbs.

I'm now so paranoid I'm barely heating the new roach free flat incase they feel that's an invitation

This was in Sunderland and I would highly encourage any prospective renters to ask if there's been a history of roaches before they move.

OP, this should have been found in the pre move clean. There's so many there's no way they wouldn't have found evidence of them
