Eddie,
Firstly do you have the turnover yet to be thinking of 5 employees or is that your plan of where you would like to be?
Also do you intend to be a "hands on" working employer or just in a supervisory capacity?
Lets say that you at present you have the turnover for one employee.
The first thing I would do is check your local Job Centre and Sits Vac in the loacal paper. What is a good average wage round your area and for what sort of work?
Ok WC'ing does need skill, but do you want to pay more or the same as what a qualified tradesman ie scaffolder etc is paid? I use this as an example only, i am sure you will catch on to what I mean!
For example the figures you have quoted, if my top guy were to be earning £26k gross (his OTE is not far off that) he would have to bring in £65k nett of vat plus per annum worked out over 47 weeks to allow for holidays. Which is the best part of £1400 nett of vat per week, which is a constant £280 nett of vat per day over a 5 day week.
Is your £26k going be a set figure or is it going to be made up of hourly rate and bonuses? You need some incentives along the way to get the best out of people!
Is £26k your maximum rate you will pay? If so, where do you go from there? There is no incentive there for an employee to want to better himself!
Personally, and this is how we pay , I think that an hourly rate around the going average for your area, plus bonuses (which can be forfieted if requirements are not met) is the best way to motivate and to give a good level of pay. Our top guy is on OTE of £24k gross in his first year, he has put himself out, he has worked unsociable hours when others didn't want to and except for the odd slip now and again, his standards are first class and work ethics second to none.(yes he is Polish) The job was advertised as OTE £20k per annum, but once he was trained and had got into a routine, he soon saw his own potential for earning more! which of course then brings us more in too!
Hope this has helped and If I think of anymore I'll add on to it
