Why Energy Saving Matters for Renters

As a UK renter, you might think your energy bills are simply something you have to accept. However, the reality is that many renters waste significant amounts of energy through simple habits and outdated habits—and you don’t always need your landlord’s permission to make improvements. With energy prices remaining volatile and Ofgem’s price cap affecting millions of households, finding ways to reduce consumption is more important than ever. The good news? Many energy-saving measures cost nothing or very little and can be implemented immediately in your rental property.

The average UK household spends around £1,700 annually on energy bills, according to recent figures. For renters, this expense often feels unavoidable, but strategic changes can genuinely reduce this figure by 10-20%. Whether you’re paying your own bills or they’re included in your rent, saving energy benefits everyone—the planet, your finances, and your landlord’s costs.

Heating and Temperature Control

Heating represents the largest proportion of UK household energy consumption, accounting for approximately 60% of your energy bill. The most impactful step is adjusting your thermostat. The Ofgem-recommended temperature for living spaces is 21°C, whilst bedrooms should be around 18°C. Reducing your thermostat by just one degree can save approximately £35-£40 per year. This might sound modest, but it’s completely painless and requires zero investment.

Consider using a programmable thermostat if your rental includes one, or ask your landlord about installing one—it’s a genuine energy-efficient improvement many landlords will approve. Programme your heating to turn off when you’re away from home and overnight. Additionally, closing internal doors in unused rooms prevents heating wasted space, and using draft excluders under doors costs just a few pounds but significantly reduces heat loss.

Thermal curtains and heavy-lined curtains are renter-friendly additions that trap warm air and cost between £20-£60 per window. Use them religiously during winter evenings to reduce heat loss through windows, which account for roughly 10-15% of household heat loss.

Lighting and Electrical Consumption

Lighting typically accounts for 15% of household electricity usage. Switching to LED bulbs is perhaps the single most effective renter-friendly improvement you can make. LED bulbs use approximately 75% less energy than traditional incandescent bulbs and last considerably longer—typically 25,000 hours compared to 1,000 hours. Yes, LED bulbs cost more initially (around £3-£8 per bulb), but they pay for themselves within months through reduced electricity consumption.

Beyond bulbs, build habits around lighting. Turn off lights when leaving rooms—obvious but frequently overlooked—and maximise natural daylight during daytime hours. In winter, this might seem impossible, but open curtains during daylight hours and position yourself near windows when possible. Motion-sensor light bulbs in hallways and bathrooms automatically switch off when nobody’s present, eliminating waste from forgotten lights.

Water Heating and Hot Water Usage

Hot water heating represents a significant energy expense, typically accounting for 15-20% of your energy bill. The simplest approach is reducing water temperature. Your boiler’s default setting is often unnecessarily high—many are set to 60-65°C when 50°C is perfectly adequate for most purposes. Ask your landlord if you can adjust this, or request they do so.

Install a water-saving showerhead, which typically costs £15-£30 and restricts flow without reducing pressure. Reducing your shower time from ten minutes to five saves roughly £15-£20 annually per person in your household. Additionally, fill kettles with cold water only as much as you need—boiling excess water wastes both energy and money.

For laundry, wash clothes at 30°C rather than 40°C or higher. Modern detergents work effectively at lower temperatures, and you’ll save approximately £40-£60 yearly without sacrificing cleaning quality.

Appliances and Energy-Efficient Habits

Whilst you likely can’t replace your landlord’s appliances, you can use existing ones more efficiently. Fully load your washing machine and dishwasher before running them—partial loads waste proportionally more energy. Air-dry clothes instead of using the tumble dryer, which is one of the most energy-intensive household appliances.

Switch off appliances at the wall rather than leaving them on standby. Standby mode consumes energy continuously and collectively can add 5-10% to your electricity bill. Televisions, computer monitors, phone chargers, and kitchen gadgets all consume standby power—use a power strip to switch everything off simultaneously.

Refrigerators and freezers run continuously, so maximise their efficiency. Keep them at appropriate temperatures (3-5°C for fridges, -18°C for freezers), ensure door seals are intact, and position them away from direct sunlight and heat sources. Don’t leave fridge or freezer doors open longer than necessary.

Insulation and Draught Prevention

Most rented properties have poor insulation compared to modern standards. Whilst you can’t install cavity wall insulation or loft insulation without landlord permission, you can prevent draughts affordably. Draught excluders around doors and windows cost £10-£30 and meaningfully reduce heat loss. Weatherstripping on window frames provides similar benefits.

Heavy rugs provide thermal insulation for flooring and create psychological warmth alongside practical benefits. Closing curtains at dusk traps warm air inside, and using thermal blinds specifically designed for insulation offers enhanced performance.

Switching Suppliers and Tariffs

Beyond consumption-based savings, optimising your energy tariff is crucial. Ofgem’s price cap changes quarterly, but your current supplier might not offer the cheapest deal for your circumstances. Compare suppliers annually using independent comparison websites and switch if savings exceed £50. Fixed-rate tariffs protect against price increases, though they’re not always cheapest initially.

Consider time-of-use tariffs if your usage patterns are flexible—Economy 7 tariffs offer cheaper electricity during off-peak hours, which works well for running appliances overnight.

Final Thoughts

Energy saving for renters needn’t be complicated or expensive. The most impactful measures—adjusting your thermostat, switching to LED bulbs, reducing shower time, and using appliances efficiently—cost nothing or minimal amounts whilst delivering substantial savings. Combined with switching suppliers and preventing draughts, you can realistically reduce your annual energy bill by £200-£400.

Start implementing these tips immediately. Compare your current energy supplier today and make small habit changes that compound into significant savings. Your wallet and the environment will thank you.
