Recently all the lamps and lights in the house have started to flicker upstairs and down. Also we have a secondary fridge in the dining room. When it's compressor kicks in it is really noisy and this causes one of the lamps to crackle. Also don't know if it is a coincidence but our LCD tv gave up the ghost with no warning. Been in house sincere march 2015, ,looks to have been rewired fairly recently. Do we need a sparky out and if So what should he be looking for?
