Lenders are always changing and updating the products that they offer. This can mean that the products you see when you check your eligibility may not be available if you check again later.
The information we use to calculate your eligibility is also being updated regularly, this could impact your eligibility for certain products. You may be eligible for a product at one stage but updates to your information could mean that you are no longer eligible.
The lenders are also reviewing their criteria often and may change their criteria for certain products which can mean that you may not see a product that you expected to see.
