There is a tendency in the mortgage market to judge performance by how much business is coming through the door. Applications, approvals, offers and lending volumes all provide useful indications of activity, but I wonder whether we sometimes pay too little attention to what happens after a mortgage offer has been issued, particularly given the time and resources already invested in reaching that point.
An offer is an important milestone for borrowers and brokers, but from a lender's perspective, it also represents business that has yet to materialise. Until the funds are advanced, there remains uncertainty over whether that anticipated lending will contribute to the loan book, and the latest set of industry data provide an interesting backdrop to this discussion.
The Bank of England's Q3 2026 Credit Conditions Survey highlights a challenging lending landscape, with lenders reporting a decline in demand for both house purchase mortgages and remortgaging during the three months to the end of August. The availability of secured credit also decreased, although lenders anticipated a slight improvement in the following quarter.
While these figures measure different aspects of the market, they raise an interesting commercial question. When new business is harder to generate, shouldn't greater attention also be paid to how effectively existing mortgage offers translate into completed lending?
The commercial value of completion
Consider the work involved in reaching the point where a mortgage offer can be issued. A lender has assessed the borrower, considered affordability, evaluated the property and undertaken the necessary underwriting and risk checks, while brokers have invested considerable time in understanding their client's circumstances and progressing the application.
By this stage, significant work has been completed, yet the transaction remains dependent on several other parties and processes before the lending can take place.
Of course, not every case that fails to complete represents a problem with the mortgage process. Buyers change their minds, sellers withdraw, chains collapse and circumstances can alter unexpectedly, meaning some transactions will inevitably fall through regardless of how efficiently those involved operate.
However, there is an important difference between transactions that fail for reasons largely outside anyone's control and those where avoidable complications contribute to delays or ultimately prevent a purchase from proceeding.
Understanding that difference could have considerable commercial value. A mortgage that does not complete represents anticipated lending that never materialises, despite the time and resources already invested in reaching the offer stage, while cases that remain unresolved for extended periods can make it harder to forecast business volumes and allocate operational resources.
Even modest improvements in the proportion of offers progressing through to completion could therefore have meaningful consequences, particularly for lenders operating at scale.
Are we measuring the right things?
The mortgage industry has invested heavily in improving the application and underwriting process, with faster decisions and more efficient systems making a genuine difference to brokers and borrowers. The issue is that those benefits can be diluted if the remaining stages of the transaction are characterised by repeated requests for information or issues that take longer than necessary to resolve.
Offer-to-completion conversion rates are one useful measure, but the underlying information could be equally valuable. Identifying where transactions regularly encounter difficulties, which requirements generate repeated clarification and whether certain issues could be addressed earlier would provide a clearer understanding of where improvements might be made.
Importantly, this should not be viewed solely as a lender responsibility. Conveyancers have their own professional obligations and risk considerations, while mortgage intermediaries often find themselves managing borrowers' expectations when progress slows, despite having limited influence over the underlying cause.
A better understanding of these different perspectives could help identify where established requirements are necessary and where existing practices may be creating work without delivering a corresponding benefit.
Looking at the bigger picture
One of the challenges facing the industry is that mortgage lending and property transactions have historically developed around different processes and priorities, even though the parties involved are ultimately working towards the same outcome.
A lender may regard the issue of an offer as evidence of a successful underwriting process, while the borrower is understandably more concerned with whether they can complete their purchase within the expected timeframe. Bringing these perspectives closer together does not mean compromising lending standards, but it does require a willingness to examine how existing processes operate in practice.
There will always be factors outside a lender's control, but that makes it even more important to understand those that can be influenced and recognise where greater cooperation could make a measurable difference.
Applications, offers and lending volumes will rightly remain important indicators of business performance. But particularly when demand is under pressure, lenders should also be asking how effectively they are converting mortgage offers into completed lending, rather than focusing solely on the volume of business they are prepared to write.
