You delivered the work. You met your obligations. You raised the invoice. And now the client is not paying.
Unpaid professional fees are a particular source of frustration because the dispute is rarely just about the money. It often touches on the quality of the work, the scope of the engagement, whether deliverables met the brief, or whether additional work was properly authorised. These are not simple questions — and they deserve a process that can actually assess them fairly.
For accountants, consultants, architects, surveyors, engineers, agencies, contractors, and other professionals, recovering unpaid fees without court or solicitors is not just possible — for most disputes under £150,000, it is the more practical and proportionate route.
Professional fee disputes sit in a category of their own. Unlike a straightforward unpaid trade invoice for goods delivered, a professional fee dispute often involves questions of judgement — was the advice sound, did the design meet the specification, was the project managed competently, did the deliverable match what was agreed?
These questions require someone with the expertise to assess them properly. A generalist court process is not well suited to disputes involving professional judgement, technical work, or complex contractual relationships.
A neutral decision process, by contrast, appoints an independent professional with the commercial and technical expertise to understand what was agreed, what was delivered, and what is properly owed. That expertise is built into the process from the start.
Professional fee disputes arise across a wide range of sectors:
If you have delivered professional work under a commercial contract and the client has not paid — or is disputing the invoice — Dispute Neutral may be the right route.
The most effective time to agree on a dispute resolution process is before a dispute arises — not after one has developed.
Professionals who include a Dispute Neutral clause in their standard terms of business or engagement letters ensure that if a fee dispute does arise, both parties have already agreed to resolve it through a private, fixed-fee neutral decision process. There is no need to persuade a reluctant client to engage after the relationship has broken down. The process is already agreed.
This protects both parties. The professional has a clear, proportionate route to recovering unpaid fees. The client has certainty about how any dispute will be handled — without the threat of immediate court proceedings or solicitor involvement.
Dispute Neutral provides draft clauses that can be incorporated directly into your terms of business or client engagement letters. These are available in the Include us section of the site.
Under the Late Payment of Commercial Debts (Interest) Act 1998, you can add statutory interest to overdue professional fee invoices at 8% above the Bank of England base rate. You can also claim fixed compensation of £40, £70, or £100 depending on the size of the debt — per invoice, automatically, without a court order.
Note that statutory interest and fixed compensation are not generally claimable on invoices that are genuinely disputed. If the client is contesting the fee rather than simply failing to pay, resolving the dispute first is the right approach.
A letter before action is a formal written notice that you intend to take further steps — through a neutral decision process or through the courts — if the fee is not paid within a set period, typically 7 to 14 days.
It should include the invoice amount, any statutory interest accrued, the fixed compensation sum, and a clear statement of your intended next step. It does not need to be written by a solicitor. A clear, firm letter before action sometimes produces payment on its own.
For professional fee disputes — whether the invoice is simply unpaid or the client is actively contesting the work — a private neutral decision service offers a binding resolution without court or solicitors on either side.
Both parties agree to appoint an independent neutral: a legally trained professional with substantial commercial experience. The neutral reviews the contract, the scope of work, the deliverables, the invoices, and the written submissions from both sides. There is no hearing. Neither party needs a solicitor. The neutral issues a binding decision based on the documents and submissions alone.
At Dispute Neutral, that decision is issued within 10 business days of the matter being ready. The fee is fixed. The process is entirely private. It covers professional fee disputes under £150,000 in England, Wales, and Northern Ireland.
Professional fee disputes under £150,000 sit squarely in what practitioners call the sub-legal band. Solicitor-led litigation is disproportionate to the amount at stake — fees represent a significant share of what is being recovered, a large part of those costs are irrecoverable even if you win, and the process takes 12 months to five years or more.
Even the party on the receiving end of a professional fee claim is better off with a neutral process. They avoid their own solicitor costs and the risk of an adverse costs order — which in litigation can exceed the original debt.
For professional fee disputes, a neutral decision process is simply the rational choice.
Quality and scope disputes are among the most common professional fee disputes and are well suited to a neutral decision process. The neutral reviews the original brief or contract, the work delivered, any correspondence about quality or revisions, and the written submissions from both sides — and issues a binding decision on whether the fee has been earned and, if so, in what amount.
Yes, in many cases. Professional engagements sometimes operate on the basis of email exchanges, proposals, or a brief course of dealing rather than a detailed formal contract. The neutral will consider all relevant documents and communications — including what was said, what was agreed, and what was delivered — in reaching a decision.
Counterclaims can be addressed within a neutral decision process. Both parties submit their documents and written submissions, which can include any cross-claims arising from the same engagement. The neutral considers the full picture and issues a binding decision that addresses the dispute as a whole — often more efficiently than court proceedings, where counterclaims can significantly extend the time and cost involved.
Yes. Dispute Neutral is designed for commercial disputes between businesses, which includes sole traders, freelancers, and independent professionals operating under a commercial contract. The process is accessible without legal representation and is proportionate in cost for smaller professional fee disputes as well as larger ones.
If you have delivered professional work and the client has not paid — or is disputing the invoice — Dispute Neutral offers a faster, fairer, and more proportionate route to a binding outcome.
