Generally 40% of job total before tax.
hence
£60 per hour labour (I have heard it sometimes goes into the second hour!)
£50 for a cheap euro lock (which you are encouraged to drill, so the customer has to buy the lock)
Plus VAT
Customer pays approx £130
you earn approx £45
less your cis tax (about 20%) which most national companies hold onto and pay when your tax is due.
So your profit from the job is around £35 from which you must buy stock and fuel and tools to get you through the job.
And you normally get paid 30 days from the end of the month in which you did the job, (if they are paying on time).
So you could wait up to 2 months or so to be paid you £35.
Even overnight charges aren't great for you (between £90-£120 per hour) at 40% this is about £40 per hour plus parts.
And if you don't make the company enough money on the jobs you go to (by drilling) they drop you down the list and you'll only get the late night jobs or the ones no-one else will go to because its hard or a long way away.
Is it worth building up their business for them?
It's all about the tension . . .
