Wondering what peoples' opinions are on this. At some point I want to wire up the garage and I've been looking at prices for SWA cables. There's massive variation in price, 25m of 6mm 3-core seems to range from around £50-£110. Are there any brands sellers that should be avoided, is the cheaper stuff dangerous junk or will it be a genuine saving if I buy it? In particular I've been looking at tlc electrical who seem to be much cheaper than screwfix.
