About WattLock
Updated October 2026 · WattLock UK team
WattLock started with a simple question: how do you get a factory-grade power fix into a British home, without an electrician, without tools and without paying thousands?
The answer is a small plug-in device built to the UK plug standard, with an approved capacitor and a fire-resistant casing. You fit it once and forget about it.
We kept the price low on purpose – so pensioners, families and anyone watching their bills can try it, backed by a 30-day money-back guarantee.
Who we are
WattLock is a small UK online store selling one product: the WattLock Energy Saver. We focus on one thing so we can explain it properly, answer every email ourselves and look after customers after they buy.
Most of our customers are UK homeowners and renters who are tired of rising energy bills and want simple, low-effort things they can try. Many are retired or busy families who don't want apps, gadgets that need setting up, or complicated home improvements.
What we believe
- Honesty over hype – we never promise a fixed saving
- No fake reviews, ratings or countdown timers
- Products made for UK homes, with UK 3-pin plugs
- Fair bundle prices and free tracked UK delivery
- A real 30-day money-back guarantee, handled by people
How we look after you
Every order is processed through Shopify's secure checkout, packed carefully and sent with tracking. If you have a question before or after buying, email us and a member of the team will reply. If WattLock isn't right for you, our returns page explains how to get your money back within 30 days.
