That's just a result of high labour cost in western countries though. Parts for appliances are usually pretty cheap, it's getting a specialist to come out that costs an arm and a leg. A heating element for an oven will be like £40, but good luck finding someone to come out and fit it for less than £80-100. Considering you can buy a brand new oven for as little as £200(with free delivery) the option to replace something instead of repairing it is unsurprisingly tempting. The further East you go the cheaper the labour gets, so it's normal that a repair that's completely unreasonable in the UK is actually pretty reasonable in Poland or Slovakia - the same part fitting would cost you maybe 50-100PLN(£10-20)? So actually the parts are almost always more expansive than labour.
