I find this quite suprising that the largest domestic window cleaning company in the country , doesnt do this anyway , as far as Ime aware it is a legal requirement vosa can ask to see records at any time , if they are not in place then look out .
But apart from the legal aspect it makes good buisness sense , so you have a written record of any defects , any action needed with a particular vehicle , this protects both the employer and employee, you as the employer are legally bound to make sure the vehicle your staff are using is safe and road worthy , how can you do that without a written check list , , a 6 monthly visit to the garage isn’t going to pick up on any issues for a long time . All commercial (hgv or lgv) and public servjce vehicles have to have a 6 weekly maintenance check by a qualified person , to make sure they are road worthy .
The employee by doing the daily / weekly checks is also then accepting the vehicle is safe and road worthy covering his back and yours , I cannot belive a company with that number of vans doesn’t do this , just asking for trouble should the worst happen , buisness these days have to be pro active with this type of thing , I only run 3 vans but we have done this from day one , most other buisness I know are the same , I think this is an area you should be looking at very seriously, not that Ime in any position to tell you how to run your buisness, but this is a very basic level of record keeping that’s needed in the modern world .
