I am a pretty competent DIY'er and have fitted electric showers in bathrooms and new spurs and lights in kitchens at home BUT this was all before the new regulations saying work had to be carried out or checked by qualified personnel. Do the same rules apply to washrooms in caravans. I ask because we need to fit an electric towel rail to our Swift Charisma 550, primarily to dry towels in bad weather but also to supplement the pathetic blown air system in there. Has anyone done this before and do they have any advice?
