I can thoroughly recommend Kevin and his colleagues at Techmeisters.  Over the last two years, Kevin has undertaken lots of electrical work for me.  He has installed an additional double power socket in one room; installed a number of new pendant ceiling lights; installed new mains powered smoke alarms and new outdoor security lights, and he replaced the light switches throughout my house.  The care he takes with each job, and little touches like sealing around new sockets and switches, shows his attention to detail - and to doing a great job.
