You know Meta and Google Ads inside out. You’ve scaled up serious budgets and still hit your cost-per-acquisition targets. You’d rather build the campaign yourself than wait for an agency deck. And when a director asks why CPA jumped last Tuesday, you already know why, and what you’re doing about it.


Green Britain Group is home to Ecotricity, Ecotalk, Skydiamond and new brands as they launch and grow. As Head of Growth, you’ll run performance-led customer acquisition across all of them, with Ecotalk and paid media as your main focus.


This is a senior, hands-on role. You’ll be in the ad accounts every day: setting up campaigns, deciding what creative to test, fixing tracking, building the reports and standing behind the numbers. You’ll report to the Digital Growth Director and manage our Digital Growth Manager. Brand strategy, the customer proposition, organic social and content sit with other teams, so your focus stays on acquisition.


For this role, you'll need to be based within a reasonable distance and able to travel to our office in Stroud, Gloucestershire, as the role requires weekly office presence.


Key responsibilities:

  • Own paid media across Meta, Google, TikTok, Microsoft Advertising and other paid social. You’ll build, launch and optimise campaigns yourself, and you’ll know when to rely on Advantage+, Performance Max and AI Max, and when to take back control.
  • Set channel plans, budgets, forecasts and CPA targets for each brand, then hit them.
  • Run creative testing to find the hooks, formats and messages that win. Turn what you learn into sharp briefs so our Creative and Content teams can keep every platform stocked with fresh ads.
  • Own measurement from end to end: GA4, GTM, server-side tracking and conversion APIs. Build reporting in Power BI, Looker Studio or Databricks that matches back-end sales, so everyone works from the same numbers.
  • Lead a prioritised CRO test programme across landing pages and sign-up journeys, working with product, UX and technology teams.
  • Grow Ecotricity’s performance on price comparison sites. Test new channels and partnerships, such as affiliates and referrals, wherever we can win customers efficiently.
  • Support Dale Vince’s campaigning with paid media.
  • Use AI to speed up creative iteration and automate reporting, with human judgement on top.
  • Hold agencies and partners to clear targets, transparent reporting and value for money.
  • Coach the Digital Growth Manager and build the processes the team will scale on.


You will be commercially focused, analytical and motivated by targets, with significant experience in performance marketing and a track record of hitting CPA targets at scale. You will be a builder, curious about AI and new technology, without losing the human judgement and brand sensitivity that strong marketing requires. Most importantly, you will share our belief in the power of green energy, nature and sustainable business to change markets for the better.


Essential skills:

  • Expert, hands-on Meta and Google Ads skills, at a level where you could teach them. You’ll also have strong experience on TikTok, Microsoft Advertising and other paid channels.
  • A track record of hitting CPA targets while scaling significant budgets.
  • Creative performance experience, from testing hooks to writing briefs that get results.
  • A solid grip on tracking, attribution and cross-platform reporting.
  • A clear grasp of funnel economics: CPA, conversion, customer quality, retention and lifetime value.
  • The confidence to present your numbers to senior leaders, take hard questions and give straight answers, especially when the news isn’t good.
  • Experience managing people and building processes from scratch.
  • Practical experience using AI to get marketing results at scale.
  • Experience working within legal, regulatory and claims approval processes, with sound judgement on data protection, consent, brand safety and responsible AI use.


It’s a bonus if you have:

  • Experience with price comparison sites, affiliates, referrals or partnerships.
  • Agency experience, particularly at a performance or paid media agency.
  • A background in energy, telecoms or another regulated sector, or at a sustainability-led brand.
  • Experience with incrementality testing or marketing mix modelling.


What's in it for you...

  • Healthcare plan, life assurance and generous pension contribution
  • Volunteering Day
  • Hybrid Working
  • Various company discounts (including shops, gyms, days out and events)
  • Holiday of 25 days (plus bank holidays) & ability to buy/sell days
  • Cycle to work scheme, car-pooling and onsite parking available


As a valued member of the team, you will be supporting the Group Environmental Policy and its associated sustainability objectives and targets.


Flexibility statement

The fast moving nature of the business means that from time to time you may be asked to perform duties or tasks outside of your original job description on an ad hoc basis. This allows the company to utilise our people in the best possible way at all times and helps our colleagues to make the best contribution in a changing environment.


Ecotricity is Britain's overall greenest energy company- it’s more than just green energy – the breadth and depth of our work on green issues is unmatched. When we started back in 1995, we were the first company in the world to provide a new kind of electricity - the green kind.

Our mission was, and remains, to change the way energy is made and used in Britain - by replacing fossil fuels with clean, renewable energy.

We don't just supply green energy, we use the money from our customers' bills to make it ourselves too – we have built windmills and sun parks in Britain. We call this turning 'bills into mills'.


We don't just focus on energy though- we built the Electric Highway, Britain's leading network of electric vehicle charging points; we helped Forest Green Rovers become the greenest football club in the world; and we launched Britain's greenest mobile phone service, Ecotalk, where they use the money from their customers' bills to protect and regenerate Britain's lost rainforests.


Ecotricity is an equal opportunities employer and is committed to providing equality for all.
