No hardware. No contracts. Completely free to use.

Most homes waste energy.
SmartGen shows you how
and what to do about it.

Turn home energy data into smarter decisions.

SmartGen is a consumer energy insights platform that helps households understand how their homes use energy. By securely connecting to your smart meter, SmartGen turns complex usage data into clear, practical insights you can actually use.

Instead of guessing what drives your energy bills, you see where energy is being used, how your home compares to similar households, and where small changes can make a real difference.

SmartGen works automatically in the background, requires no additional hardware, and is designed to make energy decisions simpler, not more technical.

Real Savings, Real Homes

Ollie C

"I knew my inflatable hot tub would cost something to run, but I had no idea how much it was actually adding to my bill. SmartGen’s AI identified the true cost straight away. Once I saw it, I disconnected it immediately. My monthly energy bill dropped from £340 to £220, saving me £120 every month."

Max D

"I didn’t realise how much energy I was using compared to similar-sized homes until SmartGen showed me my score and the underlying metrics. The AI recommendations made it clear what was driving my usage and what I needed to change. Seeing my score improve as I acted on those insights gave me confidence that I was genuinely using energy more efficiently."

Elizabeth R

"SmartGen was a real eye-opener. Comparing my home to others of a similar size showed me that I was paying more than I needed to. The AI recommendations didn’t just explain why, they identified a better tariff through switching. That alone is now saving me over £350 a year, and I can see the improvement reflected directly in my score."

Nick S

"What stood out with SmartGen was the AI plan it created for me. I’ve already followed the short-term recommendations and started saving money straight away, and the clear medium and long-term plan gives me confidence that I’ll continue reducing my energy costs over time."

Frequently asked questions

Everything you need to know about the product and billing.

Do I need a smart meter to use SmartGen? −

Yes. SmartGen connects directly to your SMETS1 or SMETS2 smart meter to analyse your real energy usage. Without a smart meter we can’t generate your personalised insights or SmartScore.

How does SmartGen actually save me money? +

SmartGen analyses your real smart meter data and benchmarks your home against similar properties of comparable size and usage. We identify where you may be over-consuming and then generate AI-driven recommendations tailored to your home. You receive a personalised action plan covering short-term behaviour changes, mediumterm improvements and longer-term optimisation opportunities. As your usage improves, your SmartScore improves and so do your savings.

Is SmartGen free to use? +

Yes. There’s no cost to download the app or connect your smart meter. We may earn commission if you switch energy provider through SmartGen, but our recommendations are always driven by your usage data.

How is SmartGen different from my supplier’s app? +

Supplier apps show you past usage. SmartGen turns your data into intelligence.
We analyse how you use energy, benchmark your home against similar properties and generate AI-driven reports with short, medium and long-term recommendations. You receive a live SmartScore, personalised improvement plan, gamified achievements, community comparisons and CO₂ impact insights alongside smarter tariff optimisation when appropriate.
SmartGen isn’t just about switching. It’s about understanding, improving and optimising your entire energy profile.

How does SmartGen calculate my SmartScore? +

Your SmartScore is calculated using real consumption data, efficiency patterns, tariff suitability and behavioural trends. It’s a dynamic score that improves as your energy efficiency improves — giving you a clear, measurable way to track progress.

Why is switching energy with SmartGen better? +

SmartGen offers two intelligent switching options. First, our SmartGen Savings Promise — a guaranteed saving based on your real smart meter data. If we don’t deliver the projected saving, we’ll pay you up to £200 on single fuel or £300 on dual fuel.
Second, our AI Optimised Plan — where we analyse exactly how and when you use energy to find the true lowest overall cost tariff. That may not always be the cheapest daytime unit rate, but it’s the most cost-effective option for your home. We don’t guess. We analyse. And we back it with a guarantee.
