Yes...I know...but hear what others say on here too. Only time I need a cooker switch is when i change the cooker...
The use of an extension lead is not a problem for fixed, sorry, stationary appliances. The testing regulations, sorry, recommendations state that extension leads should be tested according to their usage. Those used in general, multiple usage are obvioulsy more likely to suffer damage, those serving a large, stationary appliance are not.
Case in point...large "American Fridge freezer"...plugged into a single socket at skirting level behind. It's full of food, weighs about half a ton...you need to isolate it? Pull it out? No, you go to the top of the unit and unplug it from the extension lead that has been looped up from the socket to the top of the unit...that way it can be tested. Yes, the FVI is compromised but let's be fair, it hasn't moved for 5 years, so only rodent chewing could have caused a problem...and if it tests ok, it probably is ok. Plus, if you really do want to pull it out, the length of the extension allows that...so, not a total bodge, in my view...not perfect either, but perfection is more difficult to obtain. It is possible, and I have done it, but for the vast majority of normal folks it isn't achievable. So, similarly, with washing machines and tumble driers, bring their cables into the dead space next door...ie into the adjacent cupboard, or the kickspace, and they are readily accessible. I fully accept that there are some minor risks, but I also suggest that these are minuscule compared with dragging appliances out for testing then shoving them back in, hoping that the compression/crushing of the flexes doesn't compromise the electrical safety. I'd far rather be able to check the connections in plain view than have to rely on hope that all is well behind the scene.
