Demystifying the UK energy industry: A B2B marketers’ guide

Last updated: 10th June 2024

Feeling lost in the labyrinth of UK energy jargon? You're not alone. As B2B marketing experts with a passion for the energy sector, we understand the struggle. Both marketing and the energy industry are rife with acronyms and technical terms that can leave audiences confused.

Imagine trying to explain your vital energy messages when your audience is busy deciphering MPANs and DNOs. This guide cuts through the jargon jungle, providing clear explanations for the most common terms. 

Why ditch the energy speak?

Confused customers don’t convert. When your messaging is riddled with acronyms and technical terms, potential clients may switch off. They want to understand the value you offer, not decipher a cryptic puzzle. Also, jargon can stifle the creativity of your marketing campaigns.

The golden rules of simple B2B messaging

Before we look at some of the most common words and phrases in the energy and utilities world, there are four golden rules to consider that can help you simplify your B2B messaging:

  1. Focus on benefits: Don’t just list features or technical specifications. Explain how your product or service solves your clients’ energy or utilities woes. Are you helping them reduce costs? Increase efficiency? Meet sustainability goals? Speak their language and describe their desired outcomes.
  2. Use plain language: Imagine you’re in the pub after work and you’re telling a friend what you’ve written about today. How would you explain it? Use everyday language your audiences can grasp.
  3. Make visuals your ally: Sometimes a picture – in the form of charts, infographics or diagrams – is truly worth a thousand words. Use graphics to break down complex concepts in a clear and engaging way. 
  4. Know your audience: Tailor your message to your audience’s specific needs and knowledge base. Are you talking to a seasoned energy manager, or a business owner unfamiliar with the industry? Cater your communication accordingly.
  5. Remember that clarity is king: Above all, prioritise clarity. Don’t be afraid to rewrite, simplify and test your message. Ensure it’s crystal clear and easy to understand for your target audience. 

Essential energy terms explained (A–Z)

Sometimes, jargon is simply unavoidable. However, it doesn’t have to be scary or confusing, nor make your marketing campaigns as dull as dishwater. 

When jargon can’t be avoided, it can be a good idea to simply explain it, providing your audience with a quick, easy definition. To make this task easier, we’ve provided a list of some of the most common terms in the energy and utilities industry – with a clear and straightforward definition.

  1. PPA (power purchase agreement): A long-term contract to purchase electricity from a specific generator.
  2. Renewable energy certificates (RECs): Tradable certificates representing the environmental benefits of renewable electricity.


  1. Renewables obligation (RO)/Contracts for difference (CfD): Government schemes supporting renewable energy generation.


  1. Smart meter: An advanced meter that provides real-time energy usage data to consumers and suppliers.


  1. Triads: The three peak electricity demand periods in each winter. They impact energy costs.
  2. Trigeneration: Simultaneous generation of electricity, heat and cooling.


  1. Unit charge/standing charge: The two components of your energy bill – a unit charge for the energy you use, and a standing charge for meter maintenance and other upkeep or upgrade work.
