Me too 2shoes. I was tempted to go there when my laptop (which I needed for college) broke and I couldn't get credit elsewhere.
Luckily my stepped in and allowed me to get credit in her name.
The thing with BrightHouse though is it's a rent to buy scheme, so if you ever become in a position where you cannot pay, they simply take the goods back, rather than take you to court. You can also pay in small weekly installments by cash in the shop. Which is much easier for those on lower incomes/benefits.
Also when you are struggling on such a low income even £80 for a 2nd hand cooker, if yours breaks down without notice can be unaffordable.
