Every week you wait, companies bank on you giving up. A solicitor's letter costs £200–500. LetterForce generates a structured, legally-referenced complaint letter in minutes — your first one is free.
"I'd been going back and forth with my builder for 3 months. Sent the LetterForce letter on a Monday — had a call from their managing director by Wednesday."
Companies are trained to deflect emotional complaints. The difference between being ignored and getting results comes down to structure.
Frustrated messages without structure or legal backing are easy for companies to dismiss with a generic reply.
Gets DismissedThreatening legal action without citing specific legislation signals that you don't know your rights.
No WeightA clear, referenced letter citing the Consumer Rights Act forces companies to escalate internally and respond properly.
Gets Escalated"Hi, I'm really unhappy with the work done on my kitchen. It's been weeks and nobody has got back to me. This is unacceptable and I want it sorted out ASAP or I'll be taking this further."

"I was shocked when EDF tried to overcharge me. I used LetterForce to challenge the bill, and within two weeks they issued a full credit of £1,222.09. Absolutely brilliant service—saved me hundreds and gave me peace of mind."

"My kitchen extension was a nightmare—shoddy work, missed deadlines, and the builder refused to fix anything. LetterForce helped me draft a letter citing breach of contract. Within three weeks, he refunded £4,200 rather than face Small Claims Court."

"FitLife kept charging me after I cancelled, then added a bogus cancellation fee. I tried calling for months with no luck. LetterForce generated a letter referencing the Consumer Rights Act, and within a week I had a full refund of £689.94."

No. LetterForce is not a law firm and does not provide legal advice. Our tool generates structured complaint letters that reference relevant UK consumer legislation. The letters are designed to help you communicate your complaint effectively, but they do not constitute legal counsel. If you need legal advice, please consult a qualified solicitor.
No tool can guarantee a specific outcome. However, a structured letter that references relevant legislation is significantly more likely to receive a substantive response than an informal complaint. Our letters are designed to force internal escalation within the company, which dramatically improves your chances of a resolution.
Absolutely. You have full control over the final letter. After LetterForce generates your letter, you can review, edit, and customise every part of it before downloading or copying. We encourage you to add any personal details or context that will strengthen your case.
Generic templates use the same wording for every situation — companies recognise them instantly and treat them accordingly. LetterForce analyses your specific circumstances, identifies the exact legislation that applies, and generates a unique letter tailored to your case. Every letter references the correct sections of law, includes your timeline of events, and names the specific resolution you're seeking. That's the difference between something a company files away and something that gets escalated to a manager.
Companies have internal processes for handling complaints. When a letter arrives with correct legal citations, a structured timeline, and named escalation paths (ombudsman, Trading Standards, small claims court), it triggers a different workflow. It gets flagged as a potential legal risk and routed to someone with authority to resolve it — rather than sitting in a customer service queue. The structure signals that you know your rights and are prepared to act on them.
If a company doesn't respond within the deadline specified in your letter, LetterForce can generate escalation letters. These reference the original complaint, note the failure to respond, and outline next steps including referral to the relevant ombudsman, Trading Standards, or small claims court.
A structured letter with legal references changes the equation. Your first one is completely free — just sign up to get started.
