Phoned for a quote to change a yale lock and add a chubb lock. Was quoted £156 which I felt was reasonable. Locksmith arrived called Mike who deals with the Romford area. Was ok with changing the yale, but refused to put a chubb lock on the door as I was on the 2nd floor and moaning about more than his job worth and Grenfell and door splitting. I told him fine just change the yale after changing the yale he decided ok he'll install the chubb. Came back 2 days later install the chubb and charged me £223. I won't use again as too expensive and difficult to deal with.
