A worked CMA, FCA or SFO request: scoping the notice, preserving and collecting at speed, privilege review and staged production, with a timeline, what shapes the cost and the questions counsel ask.

Ref · E-D · 2026 · §REGULATOR-CASEClass · ConfidentialJuris · England & WalesStatus · Active

A compulsory notice arrives with a four week deadline covering three business units, six custodians and two years of email, chat and pricing data. The regulator has specified formats and expects a rolling production with a clear privilege log.

This page sets out what happens at each stage and the questions counsel ask before instructing. Fees are assessed case by case and quoted in writing.

§ Timeline

What happens, and when

  1. Day 1

    Hold and notice analysis

    Issue the hold, suspend deletion policies, and break the notice into a schedule of what is actually being asked for, with the questions to put back to the case team.

  2. Day 2 to 4

    Scope agreement

    Propose custodians, date ranges, search terms and formats to the regulator in writing, so the scope is on the record before collection starts.

  3. Week 1 to 2

    Collection

    Tenant side collection of mail and chat, structured extract of the pricing data, and imaging of any device the notice reaches, with chain of custody throughout.

  4. Week 2 to 3

    Review and privilege

    Responsiveness review against the notice schedule, with a separate privilege workflow and a log in the form the regulator expects.

  5. Week 3 to 4

    Rolling production

    Produce in tranches in the specified format, with a production log tying each item to the paragraph of the notice it answers.

  6. After production

    Follow up requests

    Keep the data set live and indexed so supplementary requests, interviews and any dawn raid follow up can be answered from the same evidenced position.

§ Fees

What each stage covers

We do not publish rates. Every matter is assessed and quoted individually, because scope, data volume and urgency differ in every case. After the first call you get a written stage by stage quotation, and we do not move to the next stage without your approval.

§ FAQs

Questions counsel ask

The deadline is impossible. What do we do?
Go back in writing within days with a measured scope and a phased proposal. Regulators grant extensions to parties who show volumes and a credible plan, and refuse those who go quiet.
How do we protect privilege at speed?
Run privilege as a separate workflow from responsiveness, with a fixed reviewer group and an automated log. Clawback terms should be agreed with the regulator before the first tranche goes out.
Can you work to the regulator's specified format?
Yes. We produce to CMA, FCA and SFO specifications including load file structure, metadata fields and native formats for spreadsheets and chat.
What does responding to a notice cost?
Regulator responses are quoted against the notice schedule, because volume, deadline pressure and the number of tranches drive the work. We agree the budget in writing before collection begins.
