I want to replace two old ceiling light fittings - one in a bathroom and one in a separate shower room. The ceilings are 2.9m high. The lighting circuits do not have an earth and go through an MCB on a new CU.
Can I just replace the light fittings? If so, what criteria must the light fittings meet?
