sing a good, reputable, local electrician who takes pride in their workmanship often means you won't have any problems with your electrical installation. This becomes even more relevant when it comes to outdoor lighting. Many times I've come across outside lights with water ingress that will cause half the house to lose power when they trip the RCD.
Finding the faulty circuit and resetting the RCD is not something most people would know how to do and results in having to 'call-out' an electrician to find the problem to get some power back on, this can sometimes prove to be quite expensive, especially when there are items in your home that shouldn't be turned off for long periods of time.
If your budget allows, I'd always try to spend a little more on some good quality lights. Collingwood Lighting are regarded as some o the best outside lights on the market. I also always try to avoid burying any junction boxes, you can almost guarantee they'll get water in at some point. Getting the electrician who installed the lights (if you know who they are) to come back could be troublesome. Not knowing where to dig to find a faulty junction box could mean making holes in your garden for no reason.
As an electrician in Corsham, Chippenham and West Wiltshire, I always try to keep things simple and always think about 'future proofing' the installation. I always use the right products for the job and make sure it's installed properly. Only recently I've had to overhaul some outside lights in a local bar due to poor workmanship. There's even a regulation in the wiring regulations that says good workmanship should used!
If you need some outdoor garden lighting installed in your home, give me a call!
