In short it depends on whether you want a bit of paper with 'report' written on it or a report on the condition. IT might prove hard to get hold of the £11 electrician after a fire etc. with the insurance kicking up fuss . .
Another way to look at it: As it's hard for us to see how anyone but a pizza deliveryman can arrive do their thing do the paperwork and depart for £11 you have to conclude that either they do nothing but the paperwork or they always find something that needed £250 of repairs and half the landlords agreed to the work after they C1'd it and turned the whole house off.
Back in the days of yore I soon saw the problems with garages advertising half price MOT's
