Halifax Mortgages - 'soft' searches only?

Has anybody completed on a Halifax mortgage with only a few 'soft' searches left on CRA reports?

I bank with Halifax, and went through AIP and full application with only a few 'mortgage quotation' searches by Halifax/Lloyds - I was expecting at least a full search after exchange but none so far.

Is it possible that as an existing customer borrowing 75%LTV they have decided not to bother with a full search? I was only asked for 1 months payslip/bank statement during full application - is that considered an 'A' pass?

Thanks.
