Frequently asked questions
Will an energy monitor work with my smart meter?
Yes - energy monitors clamp around your incoming live cable inside the meter cabinet and read current independently. They work in addition to your smart meter, not instead of it. Many users find smart meter readings 5-10% inaccurate, so a clamp monitor often catches billing errors.
Do I need an electrician to install one?
Clamp-on monitors (Emporia, Sense, OWL) are non-contact and install in 10-15 minutes by clipping around an existing cable - no electrician needed. DIN-rail meters like Shelly EM require an electrician for safe installation in the consumer unit.
How much can a home energy monitor save?
Typical UK households save £100-£300 per year after installing a monitor - most savings come from identifying always-on appliances (set-top boxes, old fridges, immersion heaters left on).
