The 8-week Response Rule
The “eight-week rule” is shorthand for the deadline the FCA’s DISP complaints rules impose on lenders. Once a complaint has been made, the lender has eight weeks to issue a final response. If they don’t, you can refer to the Financial Ombudsman without waiting any longer. The rule means lenders cannot stall a complaint indefinitely, and it gives consumers a guaranteed route to escalation.

Where the rule comes from
The eight-week rule is in DISP 1.6.2R of the FCA Handbook. It applies to all FCA-authorised firms handling complaints from eligible complainants — which includes consumers complaining about consumer credit, regulated payments, banking and most other retail financial services. The rule sits alongside the four-week update obligation in DISP 1.6.1R.
What the rule actually requires
In summary:
- Within four weeks of receiving the complaint, the lender must either send a final response or a holding letter explaining why they cannot resolve it yet.
- Within eight weeks of receiving the complaint, the lender must either send a final response, or — if not — explain in writing why they cannot do so and inform you of your right to refer to FOS.
- If a final response is issued at any point in the eight weeks, the eight-week clock stops and the six-month FOS referral clock starts from the date of the final response.
The eight-week period runs from when the lender first received the complaint, not when they acknowledged it.
When the eight weeks are up
If eight weeks pass without a final response:
- You can refer the complaint to FOS without waiting any longer.
- You don’t need the lender’s permission or any further communication with them.
- You don’t lose the right to a final response from the lender — they may still send one — but you have a parallel route to FOS open immediately.
- There is no automatic six-month limit at this point; the six-month clock only starts running once a final response is issued.
In practice, going to FOS at the eight-week point can be useful if the lender is clearly stalling, ignoring the complaint, or if you have heard nothing of substance. It is less common where the lender is engaging with the complaint actively but has just asked for more time.
The four-week update letter
The four-week milestone is also worth knowing about. If the lender has not resolved the complaint by week four, they must send a written update. This letter:
- Confirms the complaint is still being considered.
- Explains why a final response has not yet been issued.
- Sets out an expected timeframe for the final response.
- Reminds you of your right to refer to FOS if more than eight weeks pass without final response.
A four-week update is not a final response. It does not start the six-month FOS clock. It is purely an update.
Lender’s rights to extend
There is no formal mechanism for the lender to extend the eight-week period. They can ask you to wait longer, but you are not obliged to. In practice, if the lender is actively investigating and has good reason for needing more time (a complex multi-loan history, vulnerability considerations, missing data they are trying to obtain), waiting may be the better practical call. If they are simply unresponsive, going to FOS is the right step.
What counts as “receiving” the complaint
A complaint is received when it reaches the lender’s complaints function — which can be by:
- Email to a complaints address.
- Letter to the registered office or complaints department.
- Online form on the lender’s website.
- Telephone call to a customer service line, where the call is escalated to a complaint.
- Verbal expression of dissatisfaction in branch (which the firm has to log).
For evidential clarity, written submission — email or letter — is the cleanest. It creates a dated record that the eight-week clock has started.
When eight weeks isn’t enough
For complex cases, eight weeks can be tight. The rule does not stop the lender resolving the complaint after eight weeks, and many do — they just have to acknowledge they have run over the deadline and remind you of your FOS rights. For your part, you have to choose between:
- Waiting for the lender to finish their investigation, with the chance of a substantive offer at the end of it.
- Going straight to FOS, with the certainty of an independent review but a longer overall timeline given FOS’s backlog.
The right answer depends on the case. A lender that is engaging actively and has asked for more time is usually worth giving more time. A lender that is silent or generic in their communications is usually worth referring to FOS at the eight-week point.
