From days of drafting to impact in minutes.
Mercurial turns weeks of drafting, approvals, and channel-juggling into a single, AI-powered workflow — so your team can communicate further, faster, better and for far less.
No card required. Live demo with a council comms specialist — not a salesperson.
Briefed, drafted, approved, published - before lunch.
Trusted by communications teams across UK councils and combined authorities
The problem
Local government communications has never been harder.
Residents expect instant, personal, multi-channel updates. Members expect briefings the moment a decision lands. Statutory notices, consultations, recruitment, recycling rounds, road closures, school admissions, public health, emergency comms — every one of them is now a campaign. Budgets are shrinking. Headcount is frozen. Something has to give.
The platform
One platform. Every channel. Every resident.
Mercurial combines generative AI, audience intelligence, and full-channel orchestration into a single secure platform built specifically for the public sector. Brief it once — it writes, translates, approves, schedules, publishes, and measures across web, email, SMS, social, WhatsApp, member briefings, and print.
*Based on Mercurial customer benchmarking with 20 UK councils, 2024–2026. Indicative; verified during onboarding.
What changes for your team
- Days of drafting become minutes of review.
- One officer can run what used to need three.
- Engagement reaches communities your team has never reached before.
- Members and residents get the same information, at the same time, in the right language.
- Headcount pressure becomes a productivity opportunity — not a service cut.
Workflow
From brief to broadcast in four steps.
What used to take days of drafting, chasing approvals, and channel-by-channel publishing now happens in a single, auditable flow — in minutes.
- 01Brief
Paste a policy paper, member report, meeting notes, or even a voice file. Mercurial reads context from your CMS, intranet, and the hive brain.
- 02Generate
Mercurial drafts content for every channel: web page, news article, email, SMS, push, social posts, member briefing, large-print and Easy-Read versions, and translations.
- 03Approve
Smart routing ensures sign-off by a Mercurial comms expert before being sent back to the user. Sign-off is logged with a full audit trail.
- 04Publish
Complete jobs in minutes that would normally take days — and have more time to deal with the bigger picture rather than the communications minutiae.
A typical council waste-round change used to take eight working days, three officers, and seven separate logins. With Mercurial, the same campaign is briefed, drafted, approved, and published before lunch — by one officer.

Every capability your team needs - working at the speed of need.

FAQ
Answers for comms, IG, and procurement.
Is Mercurial GDPR-compliant?
Yes. Mercurial is fully compliant with UK GDPR and the Data Protection Act 2018. We are UK-hosted, ISO/IEC 27001 and Cyber Essentials Plus certified, and we publish our sub-processor list.
Does Mercurial use my data to train AI models?
No. Your data is never used to train third-party models. Optional, opt-in fine-tuning on your own corpus is available within your tenant only.
How quickly can we get started?
Most councils are live within 4–6 weeks. Essentials customers can self-serve in under a day.
How does Mercurial reduce headcount pressure?
Mercurial typically removes 70–90% of routine drafting and channel management time, allowing teams to absorb vacancies and reassign officers to community engagement rather than cutting service.
What integrations are included as standard?
Microsoft 365, GOV.UK Notify, Modern.Gov, and major council CMSs are included. Additional connectors are available, or can be built via our API.
Can we run Mercurial alongside an in-house AI policy?
Yes — Mercurial is designed to live within your AI assurance framework. We provide AI usage logs, model documentation, and accessibility/bias testing on outputs.
What does a typical ROI look like?
Councils typically see payback in under six months from agency, design, and translation savings alone, before any productivity gains.
How is Mercurial procured?
Via G-Cloud 14, direct contract using standard local-government terms, or through frameworks such as NEPO, ESPO and YPO.
