The Opportunity

Problem

Politicians like Andy Burnham use vague terms like 'greater public control' of water and energy without explaining what it actually means in practice.

Solution

An interactive simulator that lets users design their own version of 'public control' — municipal company, worker co-op, not-for-profit trust, etc. — and instantly see projected effects on bills, investment, jobs and environmental outcomes using real Greater Manchester utility economics.

Target Audience

Politically engaged UK voters and Greater Manchester residents frustrated with water utilities

Differentiator

The only scenario modeller calibrated against actual United Utilities regulatory accounts and Ofwat data, allowing side-by-side comparison of 7 distinct ownership models.

Competitive Analysis

Carbon Brief

carbonbrief.org
Free
Strength

Excellent energy policy analysis

Weakness

No interactive modelling tool

Our Advantage

Users can create their own models, not just read ours

🏰 Moat Strategy

Complex financial model that accurately replicates Ofwat price review methodology - very hard to replicate without regulatory accounting expertise

⏰ Why Now?

Ofwat's ongoing PR24 price review and multiple calls for public ownership create urgent need for credible modelling tools

Risks & Mitigation

technicalhigh severity

Model produces unrealistic outputs

Mitigation

Validate against real regulatory submissions and publish methodology openly

marketmedium severity

Too complex for average voter

Mitigation

Offer one-click preset models with plain English explanations

Validation Roadmap

pre-build10 days

Create interactive prototype in Google Sheets and share with 25 local activists

Success: At least 18 provide positive feedback and want full version

mvp18 days

Run workshop with 15 participants building scenarios live

Success: 80% say they would pay £19/month

Pivot Options

  • B2G version sold to local authorities
  • Expand to NHS, railways, and other privatised services
  • Educational tool for schools and universities
