Professional Fees Recovery

Why professional fee disputes are different

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, puts the documents in front of an independent lawyer with at least 15 years' practical experience, acting as an expert, not an arbitrator, whose job is to work out what was agreed, what was delivered, and what is properly owed.

Who this applies to

Professional fee disputes arise across a wide range of sectors:

• Accountants and tax advisers — fees for accounts preparation, tax returns, audit work, advisory services, or ongoing compliance work
• Consultants and advisers — management, strategy, financial, HR, or specialist consultancy fees
• Architects and designers — fees disputed over design stages, planning outcomes, or project variations
• Surveyors — fees for valuations, surveys, or professional reports contested after delivery
• Engineers — structural, mechanical, civil, or specialist engineering fees disputed over scope or sign-off
• Agencies — marketing, creative, PR, or digital agency fees contested over deliverables, results, or contract terms
• Contractors — fees for project work disputed over completion, snagging, or variation orders
• Freelancers and independent professionals — any situation where a client has failed to pay for work completed under a commercial contract

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.

A note on construction work

If you are an architect, engineer, surveyor, contractor or trade working on a construction project for a business, your contract is likely to be a “construction contract”. Under the Housing Grants, Construction and Regeneration Act 1996, either party has a statutory right to refer a dispute to adjudication, even if the contract says nothing about it. Neither side has to use that right, and the parties can agree to use Dispute Neutral instead.

Many smaller jobs run on little more than a quote and an acceptance, with few written terms. That is why a Dispute Neutral clause in your terms of business helps: it sets out in advance how a payment dispute will be decided.

Work for homeowners is a consumer contract, so consumer law applies and Dispute Neutral cannot currently decide it.

Include Dispute Neutral in your terms of business from the outset

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 with business clients 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.

Your rights on unpaid professional fees

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 in force on the 31 December or 30 June before the debt fell due (11.75% for debts falling due in 2026). That rate stays fixed for the debt. 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. This applies to clients who are businesses, not consumers.

A dispute does not remove these rights. If the client contests the fee and it turns out to be owed, interest and compensation still run from the original due date. The dispute itself still needs resolving.

Send a formal letter before action

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. For a business client, 14 days is usual. If the client is a sole trader, the Pre-Action Protocol for Debt Claims applies: allow 30 days and include the protocol's information sheet and reply form.

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.

Use a private neutral decision service

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, and without either side needing a solicitor.

Both parties agree to appoint an independent neutral: an independent lawyer with at least 15 years' practical experience, acting as an expert, not an arbitrator. 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 in advance, in bands by claim size (from £650 plus VAT for disputes up to £4,000, rising to £1,500 plus VAT for disputes over £25,000 or a commercial decision not about money). The process is private. It covers professional fee disputes between businesses (including sole traders acting in the course of business) up to £150,000 in England, Wales, and Northern Ireland, where both parties agree to use it. It does not currently accept disputes with consumers.

The sub-legal band problem for professionals

We use the term “sub-legal band” for the range below the tipping point at which it becomes commercially viable to instruct solicitors and use traditional court processes. Professional fee disputes up to £150,000 often sit in this band. Resolving them through solicitor-led litigation is often disproportionate: legal fees can be a large share of the amount at stake, and costs can be incurred that may never be recovered, even if you win.

The client on the receiving end can benefit too. They avoid their own solicitor costs and open-ended legal bills. On the fast and intermediate court tracks recoverable costs are fixed, which limits the risk of paying the other side's costs, but on the multi-track that risk can be significant.

For many professional fee disputes, a neutral decision process is the more sensible choice.

What if my client says the work wasn't good enough to justify the fee?

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. The clauses exclude matters that need expert evidence beyond simple material such as a schedule of defects.

Can I use this process if my engagement letter or contract wasn't very detailed?

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.

What if the client has raised a counterclaim?

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. The clauses exclude matters that need expert evidence beyond simple material such as a schedule of defects.

Does this work for freelancers and sole traders, not just larger firms?

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.
