When you take into account the fact you get CNC backings which will last you pretty much forever (even if they break after a year, that's still only just over £2 a month, not taking into account the pad material) and the pad material will easily last 6-12 months from what I've heard, yeah, they're worth £25. Most people spend £400 on a frame that might only last six months to a year, and you're worried about buying a set of pads which will cost you about £2 a month? I know you got a family to provide for but you can't be that skint.
