Smart Meter Vs Wifi Router Readings Comparison Uk
Smart meters and Wi-Fi routers are both intermittent or low-power RF sources in UK homes—compare them at matched distances instead of arguing from online myths. One evening with the same meter mode, the same tape marks, and a phone-on-call control row gives a clearer picture than another supplier-letter thread.
What official UK pages already say
The GOV.UK smart meters radio waves and health page describes intermittent communication bursts and reports UKHSA findings that exposures sit well below ICNIRP guidelines. The parallel GOV.UK Wi-Fi health page notes typical Wi-Fi powers around 0.1 W with exposures small relative to ICNIRP, and no communal action required. Programme context for displays and data intervals sits with Ofgem’s getting a smart meter guidance.
Side-by-side method (one evening)
- Use RF mode only; mark 0.3 m and 1 m with tape.
- Log the meter cupboard or wall box at both distances during a quiet minute, then watch for a short burst if one appears—note peaks without inventing duty cycles.
- Repeat the same distances at the living-room router.
- Add a control: phone on a call at 0.3 m for scale.
- Keep the in-home display (IHD) mentally separate from the WAN module on the meter—do not mix their roles in your notes.

When to stop measuring
Stop when like-for-like distances are logged and you can explain the ranking to yourself in one sentence. Talk to your supplier about installation placement or display issues—not about using DIY readings as a medical reason to refuse a meter.

FAQ
Is the IHD the same radio as the smart meter WAN?
No. The in-home display is a separate consumer-facing device in the programme; keep it labelled separately in your log.
Why might the router look “busier” than the meter?
Continuous local traffic and proximity to your sofa often dominate intermittent wide-area bursts—distance and usage pattern matter more than brand fear.
