Experian have announced some changes they’ll be introducing over the next few months:
Maximum ‘score’ to increase from 999 to 1250
Score bands to change from ‘Excellent, Good, Fair, Poor, Very Poor’ to ‘Excellent, Very Good, Good, Fair, Low’
Tenants being able to opt-in to directly report their rent payments to Experian (at the moment options for doing this are through 3rd party systems).
A spokesperson for Experian said tenants would have to opt in for their rent payments to count.
“As with other data we’ll soon be including in the updated score, this reflects that more lenders are now factoring in a positive rent history in their decisions,” they said.
"Great news for renters who are paying on time, every month.!
They added that missing rent payments would have an adverse effect on someone’s credit score.
Other behaviours the new system is taking into account are cutting overdraft use, avoiding credit card advances and making mortgage overpayments.
It will also take a more detailed look at regular payments on mobile phone contracts and how often a customer may switch provider.
Experian stressed the changes would not affect someone’s ability to get credit, while eligibility for mortgages, loans or credit cards remains unchanged.
However, the changes mean that borrowers are likely to change the credit bands they are in.
