Doable? Worth doing?

In Scotland I see that there are grants available for professional
installations (which seem to be around the £1000 mark).

Are there significant savings to be had by DIYing it and are there any
significant €œgotchas€� that one needs to be aware of? I do realise that
this probably falls into the €œif you have to ask, you shouldnt be doing
it€� category of jobs but just curious to know if a) you averagely competent
DIYer could do it or b) make some saving by installing an appropriate
unconnected cable for a sparky to finish off?
