When and How to Escalate a Complaint

ComplaintsLast reviewed: 1 April 20255 min read

If a company has failed to resolve your complaint satisfactorily, or if it has gone beyond the response deadline, you have the right to escalate. Escalation means taking your complaint to an independent body — such as an ombudsman, regulator, or the courts — who can investigate and enforce a resolution.

Key points

  • You can only escalate once you have given the organisation a reasonable chance to resolve the complaint themselves.
  • Most ombudsmen require you to wait 8 weeks before referring a complaint, or accept a final response sooner.
  • A deadlock letter from the company explicitly confirms they cannot resolve the complaint and allows immediate escalation.
  • Different ombudsmen cover different sectors — using the wrong one will delay your case.
  • Ombudsman services are free to complainants and legally binding on the organisation if you accept the decision.

When Can You Escalate?

You can escalate a complaint in two main situations:

  • 8-week rule: If the organisation has not issued a final response within 8 weeks of you first raising the complaint, you are generally entitled to refer the matter to an ombudsman without waiting further.
  • Deadlock letter: If the company sends you a final response (sometimes called a deadlock letter) that you are unhappy with, you can escalate immediately — you do not need to wait for 8 weeks.

Once you have received a final response, you typically have 6 months to refer the complaint to the relevant ombudsman. After this window closes, some ombudsmen may refuse to investigate. Always act promptly once you receive a final response letter.

Finding the Right Escalation Body

The body you escalate to depends entirely on who you are complaining about:

  • Banks, insurers, credit card companies, mortgage lenders: Financial Ombudsman Service (FOS)
  • Gas and electricity suppliers: Energy Ombudsman
  • Broadband, mobile, and landline providers: CISAS or Ombudsman Services: Communications (both approved by Ofcom)
  • NHS hospitals, GPs, dentists: Parliamentary and Health Service Ombudsman (PHSO) — but only after going through the NHS internal complaints process
  • Local councils and social care providers: Local Government and Social Care Ombudsman (LGSCO)
  • Online retailers and services: Small claims court, or sector-specific ADR scheme if the trader is a member

If you are unsure which body applies, Citizens Advice can help you identify the correct route.

How to Make the Referral

When you refer to an ombudsman, you will typically need to provide:

  • Your name, address, and contact details
  • The name of the organisation you are complaining about
  • A clear description of what went wrong and the impact on you
  • Copies of all relevant correspondence, including the final response letter
  • What outcome you are seeking

Most ombudsman services accept referrals online and provide a case reference number. An investigator will be assigned to review the evidence from both sides. You may be asked follow-up questions during the investigation. The process can take several months for complex cases, but simpler cases are often resolved more quickly.

You do not need a solicitor to use an ombudsman. The service is free and designed to be accessible without legal representation.

What Happens After You Escalate

The ombudsman will review the evidence and may attempt informal resolution before issuing a formal decision. If they decide in your favour, the organisation is required to comply with their decision — for example, by paying you compensation or issuing an apology.

Crucially, ombudsman decisions are binding on the company but not on you. This means if you accept an ombudsman's award, you cannot then pursue the same matter through the courts. However, if you reject the decision, you are free to take the matter to court — though this is rarely worthwhile for smaller amounts.

If the ombudsman does not uphold your complaint, you may still be able to pursue the matter through the courts if you believe you have a strong legal case. Consider seeking independent legal advice before doing so.

Frequently asked questions

What if the ombudsman rejects my complaint?
If an ombudsman decides not to uphold your complaint, you can still pursue the matter through the courts. However, the ombudsman's findings may be used as evidence. You should seek independent legal advice before taking this step, as court proceedings can be costly even in the small claims track.
Can I escalate without trying to resolve it with the company first?
No. Ombudsmen require you to have first given the organisation a reasonable opportunity to resolve your complaint. You must have either received a final response or waited at least 8 weeks before an ombudsman will typically accept your referral.
Is the ombudsman decision legally binding?
Yes — but only on the company, not on you. If you accept an ombudsman's decision, the company must comply. If you are unhappy with the decision, you can reject it and take the matter to court, though this is rarely advisable for small amounts.
What if the company ignores your escalated complaint?
If a company continues to ignore your complaint after you have escalated formally, you should report this directly to the relevant regulator — for example, the FCA for financial firms or Ofgem for energy suppliers. Persistent failure to engage with complaints can result in regulatory action. Document every attempt to contact the company and include this record in any ombudsman or regulator referral.
Can you skip the 8-week wait and go straight to an ombudsman?
In some circumstances yes. If you receive a clear final response (sometimes called a deadlock letter) before the 8 weeks are up, you can refer immediately to the ombudsman without waiting. You can also refer immediately if the company has told you it will not change its position. The 8-week clock is a maximum — you do not have to wait if the company has already made its final position clear.
