My boiler broke & Kris visited same day. Offered to install a like for like new boiler after the wknd. During installation damage was caused to fit an unexpected awkwardly positioned pipe now preventing us from fitting the base of our cupboard & we need to reposition the light, boiler does not fit the unit (can’t close the door), & there is damage to the wall. Kris denied fault saying “you’re not bringing that up again”. Kris stood on the kitchen top with shoes on & no sheets to protect the surface, immediately stepped off when my husband walked in. Issued a discount only if I paid same day.Verified reviewerJob location: N510 Very trustworthy
