GB Bank has become a lender partner of the Financial Intermediary & Broker Association (FIBA), a move that promises to give mortgage brokers access to a wider range of specialist lending products. The tie-up is designed to strengthen the link between a growing challenger bank and the intermediary community, making it easier for brokers to place cases that might not fit the high-street mould.
For consumers, partnerships like this often translate into more choice, particularly if they are self-employed, have complex income streams, or are looking at properties in areas where average prices sit well below the national norm. When a lender actively works with brokers, it can mean faster decisions and a better chance of finding a mortgage that matches a buyer’s circumstances, something that could prove valuable in the current market.

Our latest analysis of property prices across Great Britain highlights one postcode district that stands out for its affordability. The cheapest postcode district here is SR1 (Sunderland) at an average of £69,939. At that level, a typical property costs less than a fifth of the average in many parts of London and the South East. For first-time buyers, investors, or those looking to upsise without overstretching, SR1 offers a striking entry point.
GB Bank’s focus on specialist lending, including buy-to-let, bridging, and commercial mortgages, could align neatly with a district like SR1. Lower purchase prices reduce the deposit hurdle, but borrowers may still need a lender that looks beyond computer-generated credit scores. A broker with access to a lender like GB Bank can explore options for a terraced house in Sunderland just as readily as for a flat in a pricier postcode. The FIBA partnership means more intermediaries will have that tool in their kit.
What the numbers tell us about SR1
The average price of £69,939 in SR1 reflects a mix of property types, from compact flats to older terraces, often within walking distance of Sunderland city centre and the University of Sunderland. While prices have edged up in many northern towns, SR1 has remained consistently below the £70,000 mark, making it a magnet for buyers seeking value. For brokers, presenting a client’s case in this price bracket can sometimes be tricky if automated valuations or standard lending criteria do not fully capture the local market. A partnership like the one between GB Bank and FIBA could help bridge that gap, giving human underwriters more context through the broker.
It is also worth noting that Sunderland’s regeneration projects, including the Riverside Sunderland masterplan, are gradually reshaping the city centre. As infrastructure improves, the profile of buyers interested in SR1 may shift, bringing in more first-time buyers and buy-to-let landlords. A lender that understands both the current affordability and the future potential of such a district can offer products that fit today’s prices while acknowledging tomorrow’s growth. GB Bank’s intermediary-first approach, now amplified by FIBA membership, positions it to serve exactly that kind of nuanced demand.
