UK energy bills are brutal.
Your water heater makes it worse.

The average UK household spends £400–600/yr just heating water. Most of that is wasted — heating water when nobody needs it, at peak electricity prices.

Existing smart thermostats control your boiler — not your immersion heater. There's nothing built for you. Until now.

Three steps to cheaper hot water

1

We install a small device on your water heater

A certified electrician fits the Snug device to your existing immersion heater in under an hour. No plumbing. No replacing your tank. Works with any electric water heater in the UK.

✓ One-time setup · no disruption
2

The AI learns your household in 2 weeks

Snug monitors exactly when you use hot water — morning showers, evening baths, washing up. It builds a model of your home and figures out the cheapest times to heat, without you lifting a finger.

✓ Fully automatic · no manual schedules
3

You get hot water when you need it, billed less

Snug heats your water overnight or when Octopus Agile rates dip — sometimes to nearly zero. It always makes sure you have hot water ready before you need it. Your bill drops. You notice nothing different except the savings.

✓ Save £200–£350/yr on average

Common questions

Does it work with my water heater?
Snug works with any standard electric immersion heater in the UK — which covers the vast majority of homes without a gas combi boiler. If you're on Economy 7 or Octopus Agile, the savings are even higher.
Do I need to replace my boiler or tank?
No. Snug fits onto your existing tank — nothing is replaced. A certified electrician connects it to your immersion heater in under an hour. No plumbing, no disruption.
What if I run out of hot water?
You won't. Snug predicts when you'll need hot water based on your patterns and always heats in advance. If you need an emergency boost, tap the app. You're also in control of overrides at any time.
How much does it cost?
We haven't announced pricing yet — waitlist members get early access and an exclusive founding member discount. The device pays for itself in under 6 months from energy savings.
Is my data safe?
Snug only collects energy usage data from your water heater — nothing personal. Your data is encrypted, stored in the UK, and never sold to third parties. Full GDPR compliance.
When does it launch?
We're running a beta programme with 50 households in early 2027. Waitlist members get priority access, founding member pricing, and a direct line to the team.
