But this is where the age old debate that planks like 90 never seem to grasp. Labour rates is not income.
There are huge regional variances and you haven't deemed it necessary to tell us where you are.
Also we can not see the job and don't know exactly what labour is involved. You also don['t know (or haven't told us) if there will be one, two or three men on the job.
Think about it a different way. What Percentage profit do you think is acceptable on a job like this. And by profit I mean after deducting some of the following (which is not an exhaustive list):
Insurance
Pension
Van maintenance
Van insurance
Accountancy fees
Rent
Equipment Purchase
Equipment Maintenance
Banking fee's
Staff costs (back office/apprentice's etc.)
Fuel
Sundries such as soldering gas, flux, solder
Stocked items
Gas Safe Registration
Compulsory training
Voluntary product training
Parking
Printing & Stationary
Telephone and internet services
Work ware
Lunch
Annual equipment servicing/claibration
We charge £84 per hour after VAT and I can assure you I and those that work for me do not take that home.
As an example for me to drive to my main area of operation and back costs around £15 per day. Just for me.
So, I shall repeat the question; and in no way am I having a pop at the OP:
What do you and the others think is a reasonable percentage of profit on your job to cover the costs of the above; WHICH you may have noticed do not cover the actual cost of living and/or a decent salary?
I have posed this question several times in threads like this and I can't remember anyone of the regular RGI bashers/smart a7ses being able to or even bothering to give an answer.
