GBE have been the only electricians I've used, since I've owned a house (5yrs). The reason is they are excellent tradespeople. They partially re-wired our original place plus put in safety switches, and did all the wiring for our extension.

Most recent job was the installation of a timer switch for a heated towel rail, re-wiring & re-positioning a light switch, and putting in a new p.point. As usual, a thorough & professional job. One of the few trade companies we've used who properly clean up after themselves - a nice touch.
