Finalised Guidance Financial Conduct Authority Page 1 of 7 1 Finalised Guidance FG25/4 THE FINANCIAL POLICY COMMITTEE’S RECOMMENDATION ON LOAN TO INCOME RATIOS IN MORTGAGE LENDING: GENERAL GUIDANCE (Revised July 2025) A. Application and interpretation Status of guidance

1. This is general guidance given under section 139A(1) of the Financial Services and Markets Act 2000 with respect to the functions of the FCA.
2. The implementation of the Financial Policy Committee’s (FPC) recommendation on loan to income ratios primarily advances the FCA’s market integrity objective as it leads to macroeconomic stability by reducing the chance of an unsustainable credit boom, which in turn leads to a more sound, stable and resilient financial system. Doing so is also compatible with the FCA’s strategic objective by ensuring that the relevant markets function well. 1 FG25/4 The Financial Policy Committee’s recommendation on loan to income ratios in mortgage lending: General Guidance (Revised July 2025)

Financial Conduct Authority Page 2 of 7 3. This guidance sets out the FCA’s expectations for following the FPC’s recommendation. 3A. This guidance was initially issued on 1 October 2014 (FG14/8). On 27 February 2017 and 11 July 2025, the guidance was revised. Application 4. This guidance applies to a firm with Part 4A permission that includes entering into a regulated mortgage contract as lender, except if it is: (1) a bank; or (2) a building society; or (3) a subsidiary undertaking of a bank or building society with Part 4A permission that includes entering into a regulated mortgage contract as lender; or (4) an insurer; or (5) a friendly society; or (6) a credit union. 5. As this guidance applies only to a firm with Part 4A permission, it does not apply to an incoming EEA firm (unless it has a top-up permission that includes entering into a regulated mortgage contract as lender). 6. This guidance applies to an overseas firm only in relation to activities carried on from an establishment in the United Kingdom. Exclusions 7. The following are excluded from the expectation on high loan to income limit set out in this guidance: (1) re-mortgages with no change to the principal sum outstanding; (2) lifetime mortgages; and (3) regulated mortgage contracts that are not a first charge legal mortgage. Interpretation 8. Interpretative provisions (including definitions in the Glossary) of the Handbook apply to this guidance in the same way they apply to the Handbook, except where a definition is otherwise provided in paragraph 10 that definition applies for the purpose of this guidance. 9. Where an expression in italics is not defined in the Glossary, it has the meaning given in paragraph 10. Glossary of terms defined in this guidance 10. For the purpose of this guidance, the following definitions apply:

B. Guidance to firms De minimis conditions 11. Condition A is that in the set of four consecutive quarters ending on 30 June 2014, a firm has entered into regulated mortgage contracts under which the sum of the credit provided is, or exceeds, £100 million, but Condition A is not met if the firm entered into less than 300 regulated mortgage contracts in that period. 12. Condition B is that during both of two consecutive sets of four quarters, a firm has entered into regulated mortgage contracts under which the sum of credit provided in each set of four quarters is, or exceeds, £150 million (from 11 July 2025, previously £100 million), but Condition B is not met if the firm entered into less than 300 regulated mortgage contracts in each of those sets of four quarters. 13. In this guidance, two consecutive sets of four quarters is computed as follows: (1) a new set of four quarters starts at the beginning of each new quarter; (2) the four quarters in each set run consecutively; and (3) for the purpose of Condition B: (a) the first set of four quarters ends on 30 June 2014 and the second set of four quarters ends on 30 September 2014; and (b) thereafter: (i) a first set of four quarters ends on 30 September 2014 and on the last day of each subsequent quarter that follow; and (ii) followed by a second set of four quarters ending on 31 December 2014 and on the last day of each subsequent quarter that follows. High loan to income limit

Financial Conduct Authority Page 5 of 7 14. If either Condition A or Condition B is met in relation to a firm, the FCA expects that by the end of each quarter, the number of high loan to income mortgage contracts that the firm enters into in the relevant period does not exceed 15% of all regulated mortgage contracts it enters into in that relevant period, unless the firm has allocated or received high loan to income allowance under paragraphs 19 to 21. 15. Where Condition A is met, the firm should carry on its regulated activity of entering into a regulated mortgage contract in a way that is consistent with the expectation in paragraph 14 from the quarter beginning on 1 October 2014. 16. Where Condition B is met, the firm should carry on its regulated activity of entering into a regulated mortgage contract in a way that is consistent with the expectation in paragraph 14 from the start of the second quarter following the end of the final quarter relevant to the determination that Condition B has been met in relation to the firm. 17. Once either Condition A or Condition B is met, the firm should carry on its regulated activity of entering into a regulated mortgage contract in a way consistent with the expectation in paragraph 14 until Condition C is met. Condition when expectation ceases 18. Condition C is that during both of two consecutive sets of four quarters: (1) the firm has entered into regulated mortgage contracts under which the sum of credit provided is less than £150 million (from 11 July 2025, previously £100 million); or (2) the firm has entered into less than 300 regulated mortgage contracts in each of those sets of four quarters. Allocation of high loan to income allowance within a group 19. A firm that is part of a group may allocate all or part of its high loan to income allowance to any member of the group. 20. If a firm has allocated any part of its high loan to income allowance to another member of the group, the number of high loan to income mortgage contracts that it enters into should be reduced by the amount of the high loan to income allowance it has allocated. 21. If a firm that is part of a group has been allocated the high loan to income allowance of another member of its group, the number of high loan to income mortgage contracts entered into by the firm should not exceed the expectation in paragraph 14, plus any high loan to income allowance allocated to it. 22. The FCA expects a firm to keep a record of any part of a high loan to income allowance it has allocated or received. Worked examples

Financial Conduct Authority Page 6 of 7 23. This paragraph explains by way of a worked example how the de minimis condition applies in the guidance. For the period 1 July 2013 to 30 June 2014 (Q3 2013 to Q2 2014), Firm X, Firm Y and Firm Z each submit four product sales data (PSD) returns. The cumulative total value of mortgages reported in those four returns for Firm X and Firm Y respectively is less than £100m and for Firm Z it is greater than £100m. On the basis of Condition A, Firm X and Firm Y are each determined to be below the threshold and therefore out of scope of the limit on the date the proposed guidance would apply. Firm Z is determined to be above the threshold and therefore in scope of the limit on the date the proposed guidance would apply. So Firm Z is expected to limit the number of mortgage loans at or above the loan to income (LTI) limit. We repeat the threshold test when the Q3 2014 PSD returns are submitted. The relevant period is now 1 October 2013 to 30 September 2014 (Q4 2013 to Q3 2014). The cumulative total value of mortgages reported in those four returns for Firm X and Firm Y respectively is equal to or greater than £100m (from 11 July 2025, £150 million). We notify both firms of this fact but there is no expectation that the firms should limit the number of mortgage loans at or above the LTI limit at this stage. The cumulative total value of mortgages reported in those four returns for Firm Z is equal to or greater than £100m (from 11 July 2025, £150 million). Firm Z continues to be in scope of the expectations of the guidance and should limit the number of mortgage loans at or above the LTI limit as recommended by the FPC. We repeat the threshold test when the Q4 2014 PSD returns are submitted. The relevant period is now 1 January 2014 to 31 December 2014 (Q1 2014 to Q4 2014). The cumulative total value of mortgages reported in those four returns for Firm X is equal to or greater than £100m (from 11 July 2025, £150 million) and for Firm Y is less than £100m (from 11 July 2025, £150 million). On the basis of Condition B, we notify Firm X that it will be Guidance consultation Financial Conduct Authority Page 8 of 9 Finalised guidance within scope of the expectations of the guidance. So Firm X will be expected to adjust its mortgage lending activities to be consistent with the expectations of the guidance and should limit the number of mortgage loans at or above the LTI limit as recommended by the FPC from the next applicable quarter (Q2 2015) beginning on 1 April 2015. However Firm Y remains below the threshold and out of scope of the expectations in the guidance on the LTI limit. The cumulative total value of mortgages reported in those four returns for Firm Z is equal to or greater than £100m (from 11 July 2025, £150 million). Firm Z continues to be in scope of the expectations of the guidance and should limit the number of mortgage loans at or above the LTI limit. 23A. The example in Table 1 explains how the four-quarter rolling limit is calculated. It shows total loan flows by quarter (A-G) and total loan flows with an LTI ratio of 4.5 or higher (a-g). The table also shows that the relevant LTI limit calculation takes into consideration flows during the last four quarters. For example, in Q1 2017 the LTI flow limit under a four-quarter rolling limit will be based on flows for Q2, Q3 and Q4 in 2016 and Q1 2017 (ie total loans

Financial Conduct Authority Page 7 of 7 flows A-D and total high LTI loan flows a-d). Note that the limit under Condition B moved to £150 million as at 11 July 2025. Table 1: how the four-quarter rolling limit is calculated Firm A’s loans flows: Quarters based on PSD reporting Q2 2016 Q3 2016 Q4 2016 Q1 2017 Q2 2017 Q3 2017 Q4 2017 Total loan flows (volume) A B C D E F G Total loans with an loan to income >=4.5 (volume) a b c d e f g Firm A’s calculation and application for the purpose of the LTI flow limit: Quarters based on PSD reporting Q2 2016 Q3 2016 Q4 2016 Q1 2017 Q2 2017 Q3 2017 Q4 2017 Percentage of flows with LTI>=4.5 under four-quarter rolling limit (a+b+ c+d) ÷ (A+B+ C+D) <15% (b+c+ d+e) ÷ (B+C+ D+E) <15% (c+d+ e+f) ÷ (C+D+ E+F) <15% (d+e+ f+g) ÷ (D+E+ F+G) <15% C. Monitoring 24. The FCA will use product sales data returns to monitor which firms meet the de minimis conditions in paragraphs 11 or 12. 25. When firms meet the de minimis conditions in paragraphs 11 or 12, the FCA will monitor their regulated activity of entering into a regulated mortgage contract for consistency with the expectation in paragraph 14, or as may be modified by paragraphs 19 to 21. 26. When a firm meets the de minimis conditions in paragraphs 11 or 12 but has not carried on its regulated activity of entering into a regulated mortgage contract in a way that is consistent with the expectation in paragraph 14, or as may be modified by paragraphs 19 to 21, the FCA may consider using its power under section 55L of the Act to, on its own initiative, require the firm to stop entering into high loan to income mortgage contracts.
