The fairness test

Published decisions in this archive show the Ombudsman doing two separate things: reading the mortgage terms, and then asking whether what happened was fair. This page sets out that structure and links to the rules it comes from.

Two questions, not one

Where a complaint concerns a fee, an interest charge or an enforcement step, the first question is usually whether the mortgage terms allowed it. That question is often answered in the business's favour. Published decisions show that the enquiry does not stop there: the Ombudsman then considers separately whether the customer was treated fairly, which is the test set by the dispute resolution rules.

This is why a decision can record that a charge was contractually permitted and still order it to be refunded, and equally why a decision can record that a borrower found an outcome unwelcome and still not uphold the complaint. Both patterns appear in the records below.

What this means in practice

  • A fee being listed in a published tariff answers the contractual question, not the fairness question.
  • Whether a step was fair is assessed on what the business knew at the time, not with hindsight.
  • Where a business is entitled to do something, decisions have considered whether it was proportionate to do it at that point, and what alternatives had been explored.
  • An Ombudsman decision determines the individual complaint. It is not a judicial precedent binding on other cases.

DRN5725301 – Arrears and unpaid direct debit fees; £1,685 refund ordered and interest on fees removed

A complaint brought through a claims management company about fees and charges added to a mortgage taken out in August 2006. Arrears fees, the cost of possession proceedings and unpaid direct debit fees had been added to the account. The Ombudsman upheld the complaint and required Rooftop to refund 31 monthly arrears management fees of £50 and six unpaid direct debit fees, totalling £1,685, and to rework the account to remove interest added to those fees.

DRN8820419 – Arrears and legal fees; Ombudsman ordered £300 of charges reversed

A complaint about the level of arrears and legal fees added to a mortgage account administered by Rooftop Mortgages Limited. Rooftop had already removed £230 of fees. The adjudicator recommended a further £250 be removed. The Ombudsman identified one additional monthly arrears management fee of £50, applied in July 2010, and ordered a total of £300 of charges to be reversed.

DRN-3955250 – Treatment of a £100 overpayment; complaint upheld and interest to be adjusted

An interest-only mortgage taken out in 2007 with another lender transferred to Rooftop Mortgages in April 2019. The borrower made a £100 overpayment which was not applied to the capital balance, because Rooftop required overpayments of at least £1,000 to be applied to capital. The Ombudsman upheld the complaint, finding the mortgage offer permitted smaller overpayments and that Rooftop had not validly varied the contract terms.

DRN-5223166 – Appointment of LPA receivers on a buy-to-let mortgage; complaint not upheld

A buy-to-let mortgage where the borrowers began having difficulty paying in mid-2023 following interest rate rises. Rooftop appointed Law of Property Act receivers to manage the property. The complaint about that appointment and about Rooftop's conduct was not upheld.

DRN-5586287 – Shortfall sale declined in 2023 and agreed in 2024; complaint not upheld

A buy-to-let mortgage held on one property within a wider portfolio. In June 2023 the borrower told Rooftop his buy-to-let business was no longer viable and that he had a buyer for the mortgaged property, but that the sale would leave a shortfall of around £15,000 which he said would be covered by the equity from the sale of another property. Rooftop declined and required full repayment on sale. The other sale did not proceed and both properties were let again. In March 2024 Rooftop started enforcement action because of the level of arrears. In April 2024 the borrower asked Rooftop to hold off, served notice on his tenants and remarketed the property. Rooftop agreed; the property sold for around £35,000 less than the asking price, leaving a shortfall of over £60,000.
