Tapo P110 Drops to £5.28 as Ofgem Hikes UK Energy Cap 13%

The energy price cap went up by 13% on 1 July 2026, and the Tapo P110 two-pack, a Wi-Fi plug with built-in energy monitoring, has dropped to an effective £5.28 through a TopCashback stack. The move puts per-appliance tracking within reach of any UK household now absorbing the £221 a year bump on a typical dual-fuel bill.

The math layers a £15.99 Amazon sale on the £23.99 list price with the £15 new-member bonus from TopCashback. Two plugs land at £5.28 for the pair, or roughly £2.64 each, with cashback tracked inside seven days. The plug itself tracks wattage, running cost and live draw, so the discount doubles as a tool for finding the appliance quietly costing the most.

The £5.28 Stack: Two Plugs for Three Pounds Each

The Tapo P110 two-pack carried a £23.99 list price before today’s stacking play, and per the Tapo P110 two-pack product page the same listing now sits at £15.99 with free delivery to most postcodes. That headline cut then layers with TopCashback’s £15 new-member sign-up bonus, paid to shoppers who put £15 or more through a partner retailer inside the qualifying window. The bonus lands inside the cashback payout, so the duo ends up at £5.28 after cashback, or roughly £2.64 per plug. Stacking is the play: take the seller sale first, then claim the cashback on top, and skip any side discount that would cut the qualifying total below £15. Outside today’s window the same two-pack most weeks sells at £14.99 to £15.99, which makes today’s effective price a real save rather than a baseline.

Adding a plug like this to a kitchen counter or living-room lamp stand is also where the household energy story turns data-driven, an angle that fits a wider trend noted in our roundup of kitchen gadgets under $25 that earn their counter space. The Tapo P110 with energy monitoring now costs less than a single Philips Hue smart plug on its own at Argos, where the Hue two-pack lists at £47.98. That makes the smart-home plug an inexpensive diagnostic for any household that wants to see what each appliance is costing.

Layered with the new-account TopCashback bonus, the effective price lands at £5.28, which works out to two plugs for three pounds each. The TopCashback Earnings page tracks the cashback within seven days of the order. Outside today’s window the £15 bonus can disappear the moment a sign-up condition changes. Buyers who already have a TopCashback account miss the bonus piece but still see the £15.99 Amazon sale in the checkout.

What the P110 Actually Tracks in Real Time

The Tapo P110 sits in any UK three-pin socket and talks to the Tapo app over 2.4GHz Wi-Fi, then reports back live on every appliance plugged into it. The official Tapo P110 feature spec on the Tapo website lists energy monitoring, schedules, timers, voice control and an Away Mode alongside remote on/off.

Energy monitoring is the part most shoppers buy it for, and the spec page is blunt about what the plug actually measures: real-time energy use, logged usage history and an estimated electricity cost once a per-kWh rate is typed into the app. Those numbers show on the plug itself for quick checks and on the smartphone for hours, days and months of history, with the math already translated from kWh into pence using the rate the owner sets. The plug’s schedule and timer feature lets a lamp, fan or fish-tank heater run only during the cheapest window of the day, which now lines up with the cheap-rate evening hours that some tariffs still offer. Voice control works with both Amazon Alexa and Google Assistant, so the same plug can be told to switch off without lifting a phone. The Amazon UK listing for the two-pack spells out the integrations and confirms the energy tracking, app control and timer lock.

What the spec doesn’t make obvious is how granular the cost picture gets once an electricity rate is set. With the July 2026 electricity unit rate running at 26.11p per kWh for direct-debit households, the app translates wattage into pence, which is where the plug earns its keep. A kettle left drawing current on a standby cycle starts to look less free, and a fan running overnight stops being an abstract fear once its hourly pence cost shows up on a phone screen. One Tapo UK shopper put it more simply in their review on the Tapo UK shopper reviews page.

Ideal for those who want to keep track of electricity, I really like how much electricity the products spend and how smart the schedule is with the time setting.

That review, lifted directly from the page, captures the use case most buyers come back to: live wattage into a price they already know. The same reviews note that the £15.99 sale price made the difference between curiosity and purchase for several buyers. Another reviewer called the energy tab ‘amazing’, pointing out that live wattage is the screen owners check most often. Across several hundred reviews, the standout feature stays the same as the spec sheet: setup, monitoring, timers in that order.

Verified Buyers Say the App Pays the Plugs Back

Verified Tapo shoppers keep pointing to four themes in their reviews on the Tapo UK store, and the patterns are remarkably consistent across hundreds of submissions. Setup comes up first, with buyers reporting the app connects to the home Wi-Fi inside a minute or two and adds the plug to Alexa inside the same session. Live energy monitoring comes up second, with multiple shoppers calling it the single feature that justifies the price, since the app shows energy use which is handy to know. Schedules tie for third, with several owners saying the timer lets them arrive home to a warm living room in winter and a cool one in summer; another shopper points out that schedules and timers work perfectly when the phone is not at home. A handful of buyers also flag the rare design downside: a double wall socket with a chunky neighbour can hide the small physical on/off button, leaving app control as the only way to flip the plug manually.

• Setup is quick, with the app connecting inside a minute and integrating cleanly with Alexa and Google Assistant.
• Live wattage appears inside the app and updates as appliances cycle on and off, with running cost shown in pence.
• Schedules and timers run whether the phone is at home or away, extending the plug’s use to security lighting and away-day scenes.
• Integration with voice assistants is reliable, with buyers reporting clean control through Echo and Google Home setups.

The design downside is small but worth flagging before a buyer commits to a multi-plug order. An owner with a chunky plug alongside the Tapo in the same wall plate may find the on/off button covered, but the app and voice control stay fully functional. Net verdict across the Tapo UK shopper reviews page: cheap to buy, and cheap to run once the user can see what each appliance is drawing.

Two Alternatives Worth Comparing Before Checkout

For readers who want a cost-only picture without the smart-home extras, the LOWENERGIE plug-in monitor is a different proposition at a different price. Per its Amazon UK listing, the unit at £11.79 shows watts, voltage, amps and cost on a backlit LCD; that’s the entire feature set. There is no app, no Wi-Fi and no voice assistant in the box. It’s a meter, not a smart plug, and the price reflects that.

The trade-off is direct: the LOWENERGIE gives one figure on one screen at one socket, while the Tapo P110 streams the same figure plus history to a phone and connects to a voice assistant for hands-free control. For shoppers who already own a smart speaker, that gap is the entire reason to spend roughly £6 more on a stacked Tapo, since the Tapo doubles as a smart switch, a timer and an Away Mode security tool. The Tapo’s extra value shows up the moment an owner wants to switch a lamp on from the train home or run a fan on a 6 a.m. timer before the unit rate climbs. The LOWENERGIE, in contrast, measures one socket at a time with no remote option, which is its job. A head-to-head check before checkout is the right framing, since both products solve the same visibility problem from very different angles.

A third option crosses the £40 line: the Philips Hue Smart Plug, sold in a two-pack at £47.98 from Argos, per the same deal roundup that surfaces the Tapo stack. It lights up for users already inside the Hue product family but does not surface live energy data at the same granularity as the Tapo. For a household building an actual smart home, the Tapo sits in the middle of the cost and feature field, with the LOWENERGIE as the cheap diagnostic and the Hue as the smart-home add-on for buyers already committed to the product family.

Ofgem’s 13% Hike and the Numbers Behind the Headlines

The context for the plug is a regulator that has lifted the cap sharply in the last two quarters. Per Ofgem’s energy price cap page, the regulator confirmed a 13% in July 2026 rise in the energy price cap covering 1 July to 30 September 2026. The Guardian reported the same 13% rise adds the equivalent of £1,862 a year to a typical dual-fuel direct-debit bill, up from £1,641 in the prior April-to-June window. That’s a £221 a year jump before any appliance-level intervention. It’s also where the data drives for keeping an eye on which socket is doing the damage, a thread picked up in our real summer tech prep checklist.

The unit-rate change is where the bill gets shaped. Direct-debit electricity climbs from 24.67p to 26.11p per kWh, and direct-debit gas climbs from 5.74p to 7.33p per kWh. Standing charges edge to 57.19p per day for electricity and 29.04p per day for gas under Ofgem’s updated Total Domestic Consumption Values.

• Energy price cap rise, 1 July to 30 September 2026: 13% (Ofgem).
• Typical dual-fuel direct-debit household annual bill: £1,862, up £221 a year (The Guardian).
• Direct-debit electricity unit rate: 26.11p per kWh (up from 24.67p).
• Direct-debit gas unit rate: 7.33p per kWh (up from 5.74p).
• Average forecast bill for October to December 2026: £1,932 (Uswitch, current predictions).

The £221 jump is what the Tapo plug is built against. An appliance the household didn’t know was drawing 200 watts around the clock becomes the first target the moment its running cost shows up on a phone screen. The same goes for a fan that runs into the early hours when the meter is climbing fastest. None of this changes the cap; it changes the slice of the cap each appliance consumes, which is the lever a household actually holds.

The October reset is forecast by Uswitch to land harder than July’s. Uswitch’s current predictions point to a £1,932 annual bill for October to December 2026, with Ofgem’s interim chief executive Tim Jarvis telling the BBC that how soon there is a Middle East peace deal will shape the figure.

How to Lock In the £5.28 Price Step by Step

The published TopCashback sign-up bonus terms are clear enough to follow without a referral link. New accounts get a £15 TopCashback sign-up bonus paid out as cashback after a single qualifying purchase of £15 or more at any partner retailer. That £15 minimum lands naturally on the Tapo two-pack at £15.99. Existing TopCashback members can still earn the standard retailer cashback, just without the £15 bonus, so the bonus is the part that distinguishes today’s deal.

Inside TopCashback, the search bar pulls up the Tapo store, where the tracked cashback rate is shown alongside any extra sign-up bonus terms. Clicking through from TopCashback sets the referral cookie, so the £15.99 Amazon sale price still counts toward the £15 minimum spend. Checkout proceeds at Amazon as normal, with no separate promo code needed. Cashback tracks to the TopCashback Earnings page within seven days of purchase. The £15 bonus arrives alongside the retailer cashback, completing the stack.

1. Sign up to TopCashback as a new member; the £15 bonus requires a £15 minimum spend at a partner retailer.
2. Search for “Tapo” inside TopCashback and click through to the retailer page so the referral cookie sets.
3. Add the Tapo P110 two-pack to the cart while the £15.99 sale price holds on Amazon UK.
4. Complete checkout at Amazon as normal; the cashback tracks within seven days on the Earnings page.
5. The £15 bonus is paid out alongside the retailer cashback, dropping the effective two-pack price to £5.28.

For existing TopCashback members, the math still favours buying now at the £15.99 sale price; the standard retailer cashback rate is small on its own, so the £15 sign-up bonus only adds value once per account. For first-time TopCashback accounts, the bonus is the entire reason this deal matters. The £5.28 effective price keeps this stacking deal live while the conditions hold.

What Could Break the Stacking Discount

The discount rests on three things, and any one can fall. The Amazon sale price is below the £23.99 list right now, but T3 reported the same plug at £14.99 during last year’s Black Friday, so the £15.99 ceiling may not hold into August if the listing reverts to list or a new deal cycle starts. The £15 TopCashback sign-up bonus is for new accounts only, so anyone who has signed up before is out of luck on the bonus front and should look at the standard retailer cashback rate instead. The £15 minimum spend lands trivially on the Tapo two-pack but trips up shoppers who try to drop the bonus onto a smaller basket or a different retailer.

The cashback timing is also worth flagging. The TopCashback Earnings page tracks cashback within seven days, which means a stuck referral, an ad-blocker running on the browser, or a checkout that didn’t start from the TopCashback link can take the £15 off the table entirely. Stacking only stacks once for new accounts, so running the bonus a second time on a smaller Tapo order isn’t an option. The household benefit of running a real-time energy monitor through the price cap’s harder quarters is the part that lasts well past the seven-day window. The £5.28 entry stays the smartest move while the three pieces above still hold.
