When and How to Escalate a Complaint

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.

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.

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.

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.

Escalation is only as effective as the evidence you bring. Ombudsmen review the same documents the organisation relied on — so a well-organised evidence pack substantially increases your chance of success. Equally, understanding the remedies available will help you frame a realistic claim.

What to include in your escalation evidence pack:

• Complaint chronology: A dated summary of every contact you made, including phone calls, emails, and letters. This is the backbone of your case — it shows what happened when, and whether the organisation met its own deadlines.
• Full correspondence: All emails, letters, and chat transcripts. If you have complaints by phone, note the date, time, who you spoke to, and a summary of the conversation immediately after the call.
• The organisation's final response letter: This is the trigger document for ombudsman referral. If you never received one, note that fact explicitly in your referral.
• Evidence of financial loss: Receipts, invoices, bank statements, or credit card records showing what you paid and any out-of-pocket costs you incurred because of the problem.
• Evidence of distress or inconvenience: Medical notes, photographs, contemporaneous diary entries, or statements from witnesses that document the non-financial impact on your daily life.
• Any previous offers of settlement: Include these even if you rejected them — they are evidence that the organisation knew there was a problem.

What the PHSO and LGSCO can award: Both the Parliamentary and Health Service Ombudsman (PHSO) and the Local Government and Social Care Ombudsman (LGSCO) can recommend a wide range of remedies, not just financial compensation. These include: a written apology; a change in the organisation's procedures to prevent the same fault affecting others; reconsideration of a decision; specific action — for example, clearing arrears caused by a council's administrative error; or a financial payment to acknowledge injustice or distress. The LGSCO does not cap its financial recommendations by statute, but payments for distress are typically in the range of £100–£1,000, with larger sums reserved for serious or sustained injustice. The PHSO similarly recommends proportionate financial remedy.

FOS award mechanics — acceptance is your choice: When the Financial Ombudsman Service issues a final decision, you have the right to accept or reject it. If you accept, the company is legally bound to comply. If you reject it, you are free to pursue the matter through the courts. The FOS can currently award up to £430,000 for complaints about regulated activities. In practice, FOS investigators often propose a provisional outcome first — this is an opportunity for both sides to comment before a final decision is issued. Take advantage of this stage to submit any additional evidence you have.

PHSO access via MP — using your MP effectively: Unlike most ombudsmen, the PHSO requires you to refer your complaint through your MP. This is known as the MP filter. Write to your MP with your complaint file and ask them to refer it to the PHSO on your behalf. Most MPs have a casework team that handles PHSO referrals routinely. If you do not know who your MP is, the UK Parliament website allows you to look them up by postcode. Be clear in your letter that you have exhausted the NHS or government department's internal complaints process and that you want the PHSO to investigate.
