There is no single eight-week rule
One of the easiest mistakes is to assume every complaint uses the same response period. It does not. The relevant clock depends on the sector, the organisation, the type of complaint and sometimes the specific product involved. A payment-services complaint can use a shorter FCA timetable than an ordinary financial complaint. Telecoms and energy have different ADR waiting periods. Council complaints can change completely when the subject is children’s social care, adult social care or a statutory appeal.
Keep separate dates for: the original complaint, internal escalation, final response, external referral, decision review and court limitation. Continued correspondence after a final response does not necessarily extend the external deadline.
Current complaint and escalation timeframes
| Sector / process | Internal timing | What happens next |
|---|---|---|
| Ordinary retail and consumer disputes | No universal statutory complaint-response period applies to every trader. Use the trader’s complaints procedure and protect any separate legal limitation or payment-dispute deadline. | ADR, card remedy, court or sector scheme depends on the transaction. |
| Financial services | Most complaints: written response within 8 weeks. Certain payment services and electronic-money complaints normally use 15 business days, with up to 35 business days in exceptional circumstances. | FOS can normally be approached after the applicable response period or final response. A valid final response normally gives 6 months to refer to FOS. |
| Telecoms and broadband | Provider must have a complaints code and take prompt active steps. | ADR after 6 weeks from the initial complaint, or earlier with deadlock. Ofcom says the deadlock referral should be less than 12 months old. |
| Energy | Supplier complaint first. | Energy Ombudsman after 8 weeks, or earlier with a deadlock or final decision. |
| Data protection complaint | Organisation must acknowledge within 30 days, investigate appropriately, keep you updated and provide a final response without undue delay. | ICO complaint after the organisation has had the opportunity to deal with the data-protection complaint. Rights-request deadlines are separate. |
| Legal services | Legal service provider has up to 8 weeks to respond. | Legal Ombudsman after final response or 8 weeks. Usually within 1 year of the problem or awareness and within 6 months of the final response. |
| General council complaint | LGSCO Code: acknowledge Stage 1 within 5 working days, full Stage 1 response within 10 working days of acknowledgement. Stage 2 acknowledgement within 5 working days and final response within 20 working days of acknowledgement. | Usually LGSCO after the final complaint stage, or where the complaint is not progressing in a reasonable time. |
| Children’s social care statutory complaint | Stage 1 response within 10 working days. Stage 2 investigation normally 25 working days, up to 65 for complex cases. Stage 3 review panel should meet within 30 working days of request. | LGSCO normally after the statutory stages, subject to delay and jurisdiction. |
| Adult social care statutory complaint | Separate statutory single-stage procedure. Complaint acknowledgement within 3 working days under the 2009 Regulations; final response no later than 6 months, although LGSCO expects complaints to progress much sooner and says up to 16 weeks is ordinarily a reasonable period before it may intervene on delay. | LGSCO after final response, or potentially where there is unreasonable delay. |
| Social housing landlord complaint | Housing Ombudsman Code: acknowledge each stage within 5 working days, Stage 1 response within 10 working days of acknowledgement and Stage 2 response within 20 working days. | Housing Ombudsman after the landlord complaint process; Code permits limited explained extensions. |
| NHS complaint in England | Complaint should be acknowledged within 3 working days and the organisation should discuss the response plan and timescale with you. The complaint should normally be made within 12 months, subject to discretion. | PHSO is the final external stage for eligible NHS complaints. |
| FOI | Most public authorities have 20 working days for the initial FOI response. Internal review is normally expected within 20 working days, up to 40 in exceptional cases. | ICO expects the internal-review route first in most cases and asks complaints to be made promptly, generally within 6 weeks of the final response or last meaningful contact. |
Complaint deadlines and legal limitation are different
An ombudsman referral deadline is not the same as the time limit for bringing a court claim. A company continuing to discuss your complaint does not automatically extend either one. If court action is a realistic option, identify the applicable limitation period separately and obtain legal advice where necessary.
Record the date that actually starts the clock
Do not rely on the date you first phoned customer service if the scheme counts the date of a formal complaint. Keep the complaint submission, acknowledgement and final response. For council stages, keep the date you requested Stage 2. For ombudsman decisions, keep the issue date and the date by which acceptance, rejection or challenge must be made.
