My brother narrowly escaped being royally ripped off by a plumber last week. Every year, he has trouble with his central heating boiler, usually needs a new thermocouple and the pilot jet cleaning. This year, after 2 attempts, the regular plumber condemned the boiler, saying replacement parts were no longer available. He quoted £2800 to fit a replacement! Having gone through all the options, he contacted the manufacturer, who said the part numbers had been changed, but were all still available. He stripped the boiler down, and found the wiring, piping and jet block in an appalling state. Armed with the new numbers, he bought the parts and a tin of leak spray for less than £30. The retailer didn't need to see a gas ticket to sell them. Rebuilt it, and it works better than ever. Took him about 3 hours. This got us thinking about becoming certified, and doing some heating and electrical work for paying customers - there must be a huge market for a couple of reasonably well-spoken, educated, middle-aged guys to do work for people who are fed up with being ripped off by the locals. As soon as the local tradesmen hear a London accent, their eyes light up and the prices double! We are both well capable of doing the work, having rewired and plumbed our own houses for many years, but would obviously need to be certified. Is there a fast track route to getting gas and electrical tickets?
