Direct labour vs main contractor
Unless you have direct experience at employing trades people and have the time and skills to manage a site directly then you should think carefully before setting off down the direct labour route. Whilst you will not be paying a contractor’s profit (typically 10 per cent) it can often be a false economy going the direct labour route.
For example, you will be taking full responsibility for the project both on site and off site should anything go wrong whereas with a main contractor you have someone to go to get problems fixed. This is especially relevant where sub-standard work has been carried out but which only comes to light sometime later. Don’t underestimate the site management and Health & Safety requirements which can be significant. Everyone from your mortgage provided to the authorities will expect you to treat the build in a professional manner.
