Hi a second recommendation for Nick --- long story but we are away and our flat is tenanted - the tenant had problems with the lock and we needed someone we could trust to change the locks which meant Nick contacting foxtons(devil's incarnate I know !) to get access etc etc. he really came to our rescue and negotiated everything including a burglar alarm that went off , police who became interested and foxton's who were hard to contact and all for what I consider a fair and reasonable charge.
