3rd time I have asked Derek to do some work on our block of flats. This time we needed to renew all the light fittings in the communal stair (9 light fittings and tubes). Derek came quickly, explained what was required and then did all the work in a few hours. Now, rather than groping about in the dark stair we have a fully lit place that is much safer and more secure. Price was fair, quality of work excellent - and he gave us a couple of additional ideas to mull over- which we will. If I need any further work done I won't be using anyone else but the Intercom Doctor and Derek
