For Accountants & Professional Advisers

We handle the dispute. You keep the client.

Most of our work arrives the same way: a general-practice accountant opens a letter that is outside their comfort zone — a COP9 offer, a Kittel notice, a personal liability notice, a winding-up threat — and needs a specialist who will not poach the client. That is the deal, in plain terms: you refer the dispute, we run it, your client stays yours. We do not do compliance, bookkeeping, accounts or returns, so there is nothing for us to take.

What we take off your desk

COP9 and Contractual Disclosure Facility cases, where the 60-day window and the outline disclosure demand specialist judgement. VAT disputes, including Kittel and MTIC input-tax denials and best-judgement assessments. Personal liability notices and security notices against directors. Discovery assessments and the time-limit arguments that defeat them. Penalty mitigation, suspension negotiations and reasonable-excuse appeals. Statutory reviews, ADR and First-tier Tribunal preparation. If it involves HMRC and an argument, it is our day job.

How a referral works

Call either office or email us with a one-paragraph outline — no client details needed at first contact. We will tell you the same day, without charge, whether the matter needs us at all; many do not, and we will say so. If it does, we quote a fixed fee before any engagement, agree with you how you want to be kept informed, and copy you into substantive correspondence so you are never explaining a surprise to your own client. Where you prefer to stay the client's sole point of contact, we can work behind you on a consultancy basis instead.

Why firms refer to us

Some of our team trained and worked inside HMRC, which shows in how we read an enquiry letter: what the inspector already knows, what they are fishing for, and where the statutory footing is weaker than the letter implies. Fees are fixed and agreed up front, so you can pass a number to your client with confidence. And we are open 8am–10pm, seven days — useful when a client rings you in a panic on a Saturday.

Free technical library

Our professional guides cover the case law advisers actually hit in practice — Martland on late appeals, discovery staleness after Tooth, the Schedule 24 penalty framework, Kittel knowledge tests, closure notice applications and more. They are free, uncluttered and written for professionals. Use them with or without us.

Got a case you want a second opinion on? A first conversation costs nothing and we will tell you honestly if you do not need us.
