We have recently had a few quotes for renovations doing on our house. Mostly recommendations and highly rated people online etc. we decided on a builder who had been recommended and also highly rated on Facebook etc. He asked for 1/4 payment as a deposit which was £1000. I made payment through my Halifax app but it wouldn't go through, Halifax fraud team asked me to call them to confirm the payment. Iv never had this before when paying somebody new so I have since paused the payment. Has anyone else had this or should I be worried about the person we have agreed to do the work to?
