TP-Link Tapo P110 Smart Plug Review — Energy Monitoring for £7 per Socket

What Makes the Tapo P110 Different?

The Tapo P110 is TP-Link's energy-monitoring smart plug — the feature that separates it from basic on/off smart plugs like the Tapo P100 at a similar price. Energy monitoring measures wattage draw and cumulative kWh consumption per connected device in real time, reporting to the Tapo app. This allows you to know exactly how much electricity your tumble dryer, electric heater, or gaming setup is consuming — information that's useful both for identifying energy waste and calculating actual running costs.

At £28.49 for a 4-pack (approximately £7.12 per plug), the P110 undercuts most competing energy-monitoring smart plugs by a meaningful margin. At 3,138 reviews and 4.5 stars, the review evidence suggests this pricing hasn't come at a quality cost.

Energy Monitoring in Practice

The Tapo app displays current draw (watts), today's energy consumption (kWh), and historical data by day, week, and month per device. For high-consumption appliances: plugging a tumble dryer into a P110 reveals its actual cycle energy draw (typically 1.5–4kWh per cycle) — information that makes the cost of tumble-drying tangible rather than abstract.

For standby power: many electronics draw 3–10W on standby continuously. A TV on standby at 5W for 24 hours consumes 0.12kWh — about 4p/day or £14/year. The P110 makes this visible and allows scheduling the plug to cut power completely overnight, eliminating standby drain on devices that don't need always-on connectivity.

During the current energy cost environment in the UK, the ability to see actual device costs in pounds and pence allows informed decisions about usage rather than general energy-saving guesswork.

Smart Schedule and Timer

Schedules and timers run on the Tapo app with day-of-week, time-of-day precision. Away Mode randomises on/off cycling during holiday periods to simulate occupancy — a deterrent-level feature for home security without requiring any additional hardware. Countdown timers allow "turn off in 30 minutes" for appliances that should run a cycle and stop without manual intervention.

Alexa and Google Home Integration

Both voice assistants control the Tapo P110 via native skills. "Alexa, turn off the dehumidifier" works for any named P110 device. The energy monitoring data is accessible through the Tapo app rather than voice — no voice assistant currently offers energy usage readout for smart plugs in a practical form. On/off and scheduling control via voice is seamless and reliable.

No Hub Required

Wi-Fi connected (2.4GHz, not 5GHz — important for homes with router separation) with no hub or bridge required. Initial setup via the Tapo app takes approximately 2 minutes per plug: power on, open app, scan QR code on the plug, connect to Wi-Fi, name the device. Each plug operates independently and simultaneously, making a 4-pack setup straightforward rather than daisy-chained.

Physical Design

UK 3-pin plug with compact profile — smaller than some competing smart plugs, important for avoiding blocking adjacent sockets in a double socket. The LED status indicator shows on/off state and can be disabled in the app for bedroom use where a persistent LED light is disruptive at night.

App Quality

The Tapo app is well-reviewed independently of the hardware — clean interface, reliable device management, and a feature set that doesn't require a premium subscription to access. Unlike some smart home ecosystems that gate energy history behind a paid tier, Tapo's full energy monitoring history is available in the free app. This is a meaningful differentiator against certain premium-branded competitors.

4-Pack Value

At £7.12 per plug for an energy-monitoring smart plug, the value calculation is straightforward. A single P110 paying for itself requires identifying and eliminating approximately 50p of monthly wasted standby draw — achievable from most homes' always-on electronics within the first month of data collection. The four-pack allows comprehensive home coverage: kitchen appliances, entertainment centre, home office, bedroom — four high-use circuits under monitoring simultaneously.

Verdict

The Tapo P110 4-Pack is the best-value energy-monitoring smart plug solution in the UK market in 2026. Energy monitoring is the feature that distinguishes smart plugs from simple timers, and the P110 implements it reliably, with useful historical data, and at a price that makes a whole-home deployment affordable. At 3,138 reviews and 4.5 stars, the endorsement data is strong.

Rating: 4.5/5 — Energy monitoring differentiated, reliable app, no hub required, excellent 4-pack value. 2.4GHz only is a minor consideration for some network setups.
