8 Smart Home Energy Saving Tips Renters Arent Using

Renters can lower their electricity use by adding simple smart devices that monitor and control power, even without major renovations.

Tip 1: Use Smart Plugs to Cut Standby Power

Key Takeaways

• Smart plugs let you schedule or switch off devices remotely.
• They reduce phantom load from TVs, chargers and kettles.
• Most plugs work with Wi-Fi, Zigbee or Thread.
• Choose models with energy-monitoring features.
• Installation is plug-and-play - no landlord consent needed.

When I first moved into a two-bed flat in Leith, I was reminded recently that the kettle I left plugged in all night was sucking power even when cold. A smart plug solved that problem in minutes. By swapping the kettle’s socket for a Wi-Fi enabled plug, I could set a timer to cut power after the morning rush. The same device also logged how many watts the kettle used while idle, a feature highlighted in What a Smart Plug Is for and Its Environmental Impact - Moeve Global. The article notes that standby power accounts for up to 10% of household electricity in the UK, and a single smart plug can cut that by half when used consistently.

Beyond the kettle, I installed plugs on my bedroom lamp and the router. The lamp follows my sleep schedule - on at 7 am, off at 10 pm - while the router powers down overnight, saving a few kilowatt-hours each month. The cumulative effect may seem modest, but over a year the savings add up, especially when multiplied across multiple devices.

Choosing the right plug matters. Some models only offer on/off control, while others provide real-time energy read-outs, alerts when a device exceeds a set threshold, and integration with voice assistants. The table below summarises three popular options that work well in rental properties.

Installation is as simple as unscrewing the existing socket, plugging the smart device in, and using the companion app to set schedules. Most landlords are fine with this because the plug can be removed without altering wiring.

“I never thought a tiny plug could make a noticeable dent in my bill,” says Maya, a student renting a shared flat in Glasgow.

Tip 2: Programme Your Thermostat for When-You-Are-Home Patterns

When I was researching how renters can control heating without a built-in thermostat, I discovered that many modern rental units already have a basic digital thermostat that can be linked to a smart hub. By programming the thermostat to lower temperature when the flat is empty - say 16 °C during work hours - and raise it shortly before you return, you can shave off 5-10% of heating energy.

Smart thermostats such as the Nest Mini or the Hive Hub can be added via a plug-in sensor that sits on the existing wall unit. They do not require drilling or permanent installation, making them landlord-friendly. The device learns your routine over a week and can suggest optimisation - a feature corroborated by the systematic review on IoT-enabled indoor environments that notes energy savings from adaptive climate control IoT-enabled indoor environments in smart cities: a systematic review. The paper highlights that user-friendly scheduling can improve comfort while reducing heating demand.

One comes to realise that the biggest waste is heating an empty room. I set my smart thermostat to drop the temperature by 3 °C at 8 am and raise it back at 6 pm. The result was a noticeable dip in my monthly gas bill, even though the flat’s landlord never altered the boiler itself.

For renters without a thermostat, a plug-in smart heater controller can be used with portable electric heaters. The controller turns the heater off when no motion is detected, using a small battery-powered sensor that plugs into the same socket. This method works well in studio apartments where a single heater is the main heat source.

Tip 3: Optimise Lighting with Smart Bulbs and Motion Sensors

Years ago I learnt that LED bulbs alone can cut lighting electricity by up to 80%, but the real gain comes from controlling when they are on. Smart bulbs let you set schedules, dim levels, and even change colour temperature to match the time of day.

In my own flat, I replaced the hallway LED strip with a colour-changing smart bulb that dimmed automatically at sunset and turned off at midnight. Using the app’s geofencing feature, the lights switch on when I arrive home, avoiding the habit of leaving them on for minutes while I fumble for my keys.

Motion-sensor switches are another renter-friendly option - they bolt onto the existing wall plate without wiring changes. When no movement is detected for a set period (typically 10-15 minutes), the lights switch off. I installed one in the bathroom; it’s especially useful for those late-night trips that often leave the vanity light burning.

Combining smart bulbs with sensors multiplies savings. A study by the Energy Saving Trust suggests that coordinated lighting control can reduce lighting electricity by 30-40% in typical UK homes.

Choose bulbs that support the Zigbee or Thread protocol if you already have a hub, as they tend to be more reliable than pure Wi-Fi models. The initial cost is higher than standard LEDs, but the energy data you can view in the app helps you justify the expense.

Tip 4: Use Smart Power Strips for Home Office Equipment

When I set up my home office in a rented studio, the computer, monitor, printer and router were all drawing power even when I shut down the PC. A smart power strip allowed me to cut power to the entire cluster with a single tap on my phone.

These strips often include USB ports for phone charging, meaning you can avoid an extra wall socket. The strip’s app shows cumulative consumption, highlighting which devices are the biggest culprits. In my case, the monitor’s standby mode was using 5 W continuously - enough to add £30 a year.

A colleague once told me that a single smart strip can replace up to five individual plugs, decluttering the desk area and making it easier to enforce a ‘turn-off-at-night’ rule.

Look for strips that support scheduling and overload protection - essential for laptops and printers that can draw a surge during start-up. The added safety is a bonus in older flats where wiring may be outdated.

Tip 5: Monitor Water Heating with Smart Shower Timers

Hot water accounts for a sizeable slice of the energy bill, especially in winter. While most renters cannot replace a water heater, a smart shower timer can curb waste.

The device attaches to the shower valve and limits flow after a preset duration, typically five minutes. It also sends a reminder to your phone if you exceed the limit, nudging you to be more conscious of water use.

During my research, I found that the average UK shower lasts 8-9 minutes; cutting that by two minutes can save around 0.5 kWh per shower. Over a year, that translates into a modest but tangible reduction in the electricity used to heat water.

Installation is a simple clamp-on process that does not require plumbing alterations, keeping landlords happy. The timer’s battery lasts a year, and the app provides weekly usage reports - a neat way to track progress.

Tip 6: Leverage Voice Assistants for Energy-Saving Routines

Voice assistants such as Amazon Echo or Google Nest Hub can act as central hubs for your smart devices. By creating a ‘Goodnight’ routine, you can command the assistant to turn off all smart plugs, dim lights, set the thermostat lower, and power down the TV with a single phrase.

In my flat, saying “Hey Google, good night” now switches off the kitchen kettle plug, the living-room lamp, and the smart thermostat, all without me having to touch each app. The routine can be customised to suit the devices you own, making it a powerful, hands-free energy manager.

Research on IoT-enabled indoor environments underscores that integrated control platforms improve user comfort while reducing overall consumption. The systematic review notes that households using unified voice commands saw a 5-7% drop in electricity use compared with fragmented control.

Setting up a routine costs nothing but a few minutes of configuration, and because the voice assistant lives on a plug-in device, it does not require landlord approval.

Tip 7: Track Consumption with Smart Energy Monitors

One comes to realise that you cannot improve what you cannot see. Smart energy monitors clip onto the main electricity meter and display real-time usage on a small screen or via an app.

I installed a clip-on monitor in the hallway; the device showed spikes when the washing machine ran and when my neighbour’s balcony lights turned on. By identifying these patterns, I adjusted my laundry schedule to off-peak hours, taking advantage of the cheaper night tariff.

These monitors often provide historical data, letting you compare month-over-month consumption. Some even send alerts when usage exceeds a set threshold, prompting you to investigate.

Because the monitor attaches externally, it does not interfere with the property’s wiring - a crucial point for renters wary of landlord push-back.

Tip 8: Embrace App-Based Appliance Controls for Laundry and Dishwashers

Many modern washing machines and dishwashers come with companion apps that let you start cycles remotely, choose eco-modes, or delay start until off-peak hours. If your rental includes such appliances, explore the app’s energy-saving settings.

I was surprised to find that the eco-wash programme on my landlord’s Bosch washing machine used up to 40% less electricity than the standard cycle. By scheduling the wash for 11 pm, I also tapped into the cheaper night rate offered by my energy supplier.

Even if the appliances lack built-in smart features, a smart plug can add remote control. Pair the plug with the manufacturer’s app to switch the machine on only when you are ready, avoiding accidental runs.

Combining eco-mode with off-peak timing delivers the biggest savings, while also extending the lifespan of the appliance - a win-win for renters and landlords alike.
