The firm's spokesperson Andy Pratt added that consumers considering a self-certification mortgage should consider getting advice on the subject.
"A very high percentage of self-cert mortgages in the UK are applied for after advice from brokers, because most customers in that circumstance need a bit of guidance, and a lot of the lenders are not high street lenders," he explained.
"If those customers carry on with that behaviour, ie consult a broker, then the broker's going to find a home for them."
Alexander Hall, which is one of the UK's leading mortgage brokers, was awarded the broker of the year award by What Mortgage for the second year running in 2007.
