Room for improvement
Credit scoring is in the spotlight as the regulator proposes more comprehensive affordability checking but the present model is far from perfect, with questions of transparency and data sharing yet to be resolved

The industry has yet to get its head around the ramifications of the Financial Service Authority’s Mortgage Market Review. The implications for the specialist market alone mean that brokers could end up writing mortgage business differently in the future.
But beyond the headlines of the self-cert ban and individual broker registration the regulator’s proposals for affordability could mean a radical shake-up in the way mortgage applications are processed. The FSA is taking a hard line on the lengths lenders and brokers go to ensure that mortgages are affordable. A big part of this is the role credit scoring plays in assessing affordability.
The FSA has suggested that all credit information should be shared by lenders via credit reference agencies. Lending decisions are generally made up of three parts - a basic credit score provided by a credit reference agency, lenders’ own credit scores and lenders’ individual rules and policies.
“Checking the data that credit ratings agencies hold about consumers will be much more important in future,” says Vera Cottrell, principal policy adviser at Which?. “But the information banks collect from credit rating agencies will also be critical as there is more pressure on lenders to show they have done their homework and checked the affordability of loans.”
Jan Smith, director of industry relations at Callcredit, one of the three big consumer credit reference companies in the UK, agrees.
“Credit scoring will play a much bigger role in lending decisions than it does now,” she says. “If you look at the Consumer Credit Directive or the Mortgage Market Review, the whole focus is on affordability. The only way of assessing that is by having more data available to allow lenders to make sensible decisions.”
But the FSA, while boosting the role of credit searches, appears to be calling them into question at the same time. The proposed clampdown on fast-track would have the perhaps unintended effect of rendering credit scoring obsolete.
Ray Boulger, senior technical manager at John Charcol, has called on the regulator to clarify its position in a recent blog.
“Identity verification can often be done electronically and sufficient information obtained for a lender to safely cut down on the paper proofs required,” says Boulger. “If the credit score is not useful in making this decision why do lenders, the FSA and the ratings agencies all regard it as so important?
“The FSA can’t have it both ways - either the credit score is a valid tool in assessing mortgage applications or it is not. If it is but the same paper proofs are required for an applicant with a high score as one with a low score, what is it achieving?”
But is it right that credit scoring should play such a central role? Recent reports in the consumer press point to widespread inaccuracies on credit profiles such as incorrect addresses and settled debts which appear as still being owed.
All these inaccuracies are time-consuming and frustrating to correct, and if they surface in the course of mortgage applications they could cause sales to fall through. Or so the newspapers would have us believe.
In reality, the Financial Ombudsman Service only recorded 21 complaints about credit reference agencies providing incorrect information in the year to October. In the same period last year just 15 complaints were made.
“We get some enquiries from consumers about credit reference agencies but they are often part of wider complaints,” says an FOS spokesman. “Some borrowers may be unhappy with their credit cards or the way their banks are handling their accounts. An issue with a credit reference agency may crop up as part of that.”
But the FOS statistics alone don’t mean that credit scoring is problem-free - at least, the Treasury Committee doesn’t seem to think so. It recently conducted an inquiry into credit searches, collecting evidence on the effect shopping around for credit may have on consumers’ credit files.
In an oral evidence session held on October 27 the assembled MPs tried in vain to get to the root of the problem. Martin Lewis, founder of Moneysavingexpert.com, told the committee that consumers can decide to go elsewhere after applying for credit with a particular lender. But he argues that any further attempt will be blighted by the fact that they have applied before.
“Consumers may try to go elsewhere but they won’t get a cheaper deal because of the impact of a credit search on their file,” says Lewis. “The system is designed to stop shopping around to the detriment of consumer choice.”
But when pressed at the meeting neither Lewis nor Eric Leenders, executive director of retail at the British Bankers’ Association, could tell MPs the number of consumers who have been disadvantaged by multiple credit scores.
Lenders supposedly take the view that many credit searches in a short period of time indicate that a prospective borrower has been turned down for credit. But written evidence from the Information Commissioner’s Office to the committee seems to suggest that this may not be the case (see box). The ICO says it can’t verify the industry claim that multiple credit searches necessarily mean customers represent a heightened credit risk. It has recommended that the committee should look into this point further.
MPs struggled to establish whether there was a detrimental effect on a consumer’s credit file from shopping around.
“We’re not saying don’t shop around,” Fiona Hoyle, head of consumer finance at the Finance & Leasing Association, told the committee. “What we are saying is that as part of the overall credit scoring and credit rating system, if you are being turned down then there may be some sense in pausing for a while.”
When pressed on the effect of multiple credit searches on consumers’ credit files Hoyle would only concede that “if you are making a large number of applications in a short period of time it will be an element that is taken into account”.
In short, the process of predicting consumer risk accurately based on previous credit history is murky. Cottrell says that what makes the issue so difficult to pin down is that every lender has its own credit scoring criteria.
“We don’t know how credit scores are put together, how fair they are, what kind of behaviour scores take into account or how that behaviour is weighted,” she says.
“These models are not transparent. One of the problems for consumers is understanding what they can do to improve their score. Banks are constantly refining and changing their credit scoring models so it’s impossible for consumers to understand how markets change models - something in your credit file that was once viewed as positive might now be seen as a negative.”
This is true for all parties in the mortgage market, let alone clients. Once upon a time working in the booming financial services industry would be something that would boost a person’s credit score. Two years on and it’s probably something that would count against them.
“There should be more transparency with regard to credit scoring and how borrowers can improve their scores when they try to take out mortgages,” adds Cottrell.
“I’m not talking about manipulating credit scores but there should be more transparency about the things consumers can do to influence and improve their scores, such as tightening up their spending habits.”
But credit reference agencies are not so sure. Smith argues that an overly transparent process could give away complicated lending policies which could be damaging information if it fell into the wrong hands.
“Fraud is so prevalent now that you can’t make credit scoring so transparent that fraudsters think that if they tick all the boxes they could fraudulently obtain mortgages,” she says.
“On one hand there’s an argument for transparency, but that should involve consumers checking their credit files and making sure that their records are up-to-date and relevant to their current circumstances. It’s true that lenders remodel their credit scores regularly but total transparency would just open the gates wide to fraudsters.
“We cannot make the process so transparent that it would open it up to fraud but it should be clear enough for borrowers to understand what their credit file means,” she adds.
The next issue on the agenda for credit reference agencies is that of data sharing. The majority of lenders already pass on most of their data to these agencies, the three biggest ones being Experian, Equifax and Callcredit. But lenders are not obliged to hand over all the information they hold on their files.
“If you only go to one credit reference agency it might not have all the information on you because other lenders haven’t given it their data,” says Cottrell.
But she notes that the credit reference industry has been working hard to refine credit scoring practices so lenders and credit firms are using the best possible information.
“Credit risk tools help lenders differentiate between good and bad risks and given the increase in data sharing in recent years we are continuing to make improvements in their performance,” says Gillian Key-Vice, head of government affairs and regulatory policy at Experian.
“Through our work with the industry and regulators we en-courage the fullest possible sharing of data to enable lenders to make the best decisions. This includes helping them validate affordability in a timely and consumer-friendly manner.”
A valiant standpoint but it doesn’t take into account another limitation of credit reference agencies - lack of access to what is called non-consented data. Granted, the companies probably have to a fairly comprehensive data stack but there is a gap in their know-ledge. This relates to borrowers who have had accounts for around 30 years but who would not have been asked for their consent to their data being shared when they applied for their loan or account. No consent means this information can’t be shared between lenders or credit reference agencies.
A government working party has been set up, which Callcredit sits on, to tackle this problem. Lenders are also involved in the talks but Smith says discussions are at an early stage. She surmises that the cost of implementing wider data sharing would be shared equally between lenders, credit reference agencies and consumers.
The regulator says the importance afforded to credit scoring by lenders is a matter for individual firms, not the FSA.
“Our focus is not on tools but on affordability,” says an FSA spokeswoman. “We are concerned about whether individuals can afford their mortgages. The extent to which credit scores are taken into account is down to each lender. All we want to see is that lenders have properly assessed affordability.”
In answer to Boulger’s argument that credit scoring will be made redundant by the proposed requirement for paper income proofs the spokeswoman says the regulator is not demanding that brokers and lenders should not fast-track deals, simply that they should verify that they have all the information before fast-tracking occurs.
The trouble is that mortgage applications can be notoriously difficult to get through, as most brokers will no doubt testify to. And Smith says credit scoring can provide an easy screen for lenders to hide behind when declining applications.
“Lenders often give the credit score as an excuse to refuse applications when it’s actually another factor,” she says. “It’s easy for them to say they ran a credit check and the individual didn’t pass it when the problem could be something else entirely.”
So although not many borrowers are lodging specific complaints about credit scoring there is clearly work to be done in refining the process. The balance lies in designing a system that is a good indicator of risk while being clear enough to be explained to clients.
More data needs to be shared so credit profiles are more representative of borrowers’ credit histories. But at the same time borrowers need to be assured that their data is being passed to the right firms and that it is adequately protected.
There’s certainly room for improvement and it may be several years yet before lenders, credit reference agencies, the government and the regulator hammer out the ideal arrangement.
Credit scoring is by no means achieving full marks at the moment and it could be some time before it can be classed as a risk-free and flawless affordability-checking tool.
The office of fair trading considers credit scoring to be an aid to responsible lending
Credit scoring takes into account information provided directly by consumers, any information held about them and any information obtained from other organisations. Where lenders use data from other organisations, lenders should inform consumers what they are. Lenders may also use information obtained from credit reference agencies.
The credit scoring system allocates points for each piece of relevant information and adds these up to produce a score. When a score reaches a certain level then generally an application is agreed. If a score does not reach this level lenders may not agree to an application. Sometimes scores are calculated by credit reference agencies and lenders may use these in their assessments.
The points allocated are based on a thorough analysis of large numbers of repayment histories over many years of providing credit. This statistical analysis enables firms to identify characteristics that predict a likelihood of future performance. For example, if individuals falling within a particular age group have proved to be more likely to meet payments than those falling within another age group the points allocated will reflect this.
Credit scoring produces consistent decisions and is designed to ensure all applicants are treated fairly. Additionally, lenders may have policy rules to determine whether they will lend. These reflect commercial experience and requirements.
Every credit or loan application involves a certain level of repayment risk for lenders no matter how reliable or responsible an applicant is.
Credit scoring enables both lenders and credit reference agencies to calculate the level of risk for each applicant based on the information obtained. If the level of acceptable risk is exceeded the application will not be accepted.
This does not mean that any declined applicant is a bad payer. It simply means that based on the information available the lender is not prepared to take the risk of granting that loan.
Lenders are not obliged to accept applications. They have differing lending policies and scoring systems so applications may be assessed in different ways. This means that one lender may accept an application but another may not. If an application is declined, this will not be disclosed to the credit reference agency.
Credit scoring is fair and impartial. It does not single out a specific piece of information as the reason for declining an application. Credit scoring methods are tested regularly to make sure they are fair and unbiased.
Responsible lending is essential for the good of applicants and lenders. The Office of Fair Trading regulates credit and considers credit scoring to be an aid to responsible lending.

No proof that multiple credit searches mean heightened risk for lenders
When a credit search is conducted it leaves a footprint on a consumer’s credit file. As we understand it, the purpose of such a footprint is two-fold - first, it enables a consumer to know that a search has been conducted and by whom, and second, it allows other lenders to see how often a consumer has applied for credit.
Credit searches should be distinguished from quotation searches, the latter being made only for the purpose of providing quotations rather than to determine credit applications. We understand that both types of search leave footprints that are visible to consumers and lenders but that they are distinguishable on the face of the credit file.
We consider it essential that these search footprints should be visible to consumers. The real question is whether they should also be visible to other lenders who may subsequently search a consumer’s credit file.
This, in our submission, should depend on whether they provide the searcher with information that they have a legitimate interest in seeing for the purposes of their search.
The credit industry’s position is that prospective creditors have a legitimate interest in knowing whether and how often an applicant has applied for credit in the past. The industry says that making several such applications over a short time period is predictive of an applicant’s financial overcommitment and even of possible fraud.
Assuming that this is true, we agree that the information is relevant to the decision on whether to grant or refuse credit and that it should be available to lenders for that purpose. We note, however, that while the logic of the industry’s position seems reasonable the ICO is unable to verify the extent to which multiple credit applications are predictive of sub-optimal credit risk. No doubt this is an issue that the committee will wish to explore with other witnesses as part of its inquiry.
We are not aware of any claims that merely shopping around for the best credit deal is predictive of increased credit risk - and we would be sceptical of any such claim were it to be made.
On this basis we see no reason why lenders making credit searches should be able to see the footprints left by earlier quotation searches as that information would be both irrelevant to the decision-making process and excessive.
Our understanding is that quotation searches do leave footprints that other lenders can see and that they may be taken into account in credit scoring but the committee may wish to confirm this with credit reference agencies.

Scorecards develop with time
When considering granting credit companies use a variety of data and procedures. Typically, they use data gathered at the point of application, from credit reference agencies and already held where the applicant is a customer.
Scorecards often form part of a policy for granting credit. They are created using reliable data collated by the lender and a credit information bureau. But critical to scorecard development is validation through time - does it still effectively manage risk so a lender is not suddenly faced with a high level of late payments or defaults? The recent economic problems highlight the importance of regular validation.
Of course, a credit scoring model can only be as reliable as the data used to build it and the performance it predicts. Indeed, the ability of credit scoring tools to reduce risk to lenders should not be underestimated in the current climate.
Instances where inaccurate information is included on an individual’s credit report are rare but advisers should always recommend that their clients obtain a copy of their credit report to ensure all data is accurate and up-to-date before they start making applications.
If incorrect data is found on an individual’s credit report the question can be raised with the credit reference agency from which the report was obtained via the online Notice of Dispute service.
The Information Commissioner’s Office recently stated that in its experience the overwhelming majority of credit reference data is accurate.
Part of the Financial Services Authority’s Mortgage Market Review considers identifying consumers’ borrowing capacity based on disposable income. To accurately assess this lenders would require not only information on existing credit commitments and income but also other details such as assets, savings, investments, how applicants spend their money, any additional credit agreements they might have and other income sources.
It may be necessary for lenders to carry out additional verification checks. For example, does the stated salary match external information already held on the consumer? This could in turn mean that extra information is supplied to or sourced by credit reference agencies with a view to improving lending decisions.
But there would be a significant cost to the industry to make such changes. For example, to verify income on every enquiry could be a costly business.
Finally, it is important to recognise how good credit scoring is for the industry. Reliable models can help lenders manage their existing customers appropriately and minimise debt in the future.”

Most mortgages fail because of a major change in a clients circumstances, not because they simply cannot afford the repayments. The situation could be vastly improved if some form of ASU or income protection was mandatory with every mortgage. The focus should be on protecting mortgages, not declining them. This would benefit the lenders and brokers.
