Where does this figure of £150 come from?
Whilst it might be possible to install the switch in 10minutes the whole job will take longer than that.
Agreed - I am just talking about a like for like comparison on the work activities related to installing a second switch.
£150 is the generally at the low end of quotes I got from 8 local electricians who I got round to my house to quote for the job.
