We applied when ds won the school's second best scholarship at CE (so he's very bright). We were roundly turned down, even though more than half our income goes on the mortgage. We remortgaged (we thus have almost no equity and even more crushing repayments) but were then turned down again.... In theory we could sell the house, but it's not very practical/spruce, and we would take a big bath if we did. (Ok, maybe it was a mistake to buy it...)
Our pretax income looks on the high side, but most of it goes on the mortgage, bills etc. We don't turn the heating on till after 31 October, and then only for two hours a day. Economy light bulbs, no foreign holidays - make that NO holidays year before last. We sold one car and the other is a Prius.
Eventually ds said he was not getting enough from the school to make it worthwhile, and he chose to leave to go to an FE coll for 6th form. We've yet to see if that works out for him.
Frankly, I think you could easily form the impression here that a bursary is relatively easy to get, but that hasn't been our experience. I have colleagues whose children have also been told 'no'.
I'm not particularly bothered about this anymore, really. We made some choices and we have to live with them.
