Top Tips for Renters: How to Slash Your Water & Electricity Bills

Renters across South Africa, especially in Gauteng, are feeling the squeeze of rising utility costs. With electricity tariffs increasing and water scarcity growing, saving on these essentials has never been more important. This guide shares Top Tips for Renters on How to Reduce Your Water & Electricity Bills effectively, without compromising comfort.

Tips for Renters: How to Slash Your Water & Electricity Bills

Understand Your Utility Usage

Before cutting costs, know where your money goes. Track electricity and water usage using prepaid meter data or smart plugs. Monitoring energy habits helps identify wasteful patterns and encourages smarter consumption.

In South Africa, prepaid systems make tracking easy. Check your daily or weekly spend, then set realistic targets to lower it.

Prioritise Your Geyser – The Biggest Energy Consumer

The geyser is responsible for up to 32% of household electricity use, according to research from Stellenbosch University. A simple timer can make a big difference. Heating water only when needed can save 12% to 18% of total electricity consumption.

Lower the thermostat to 55–60°C and insulate the geyser with a thermal blanket. These small changes reduce standby heat loss and lower bills.

Seal Gaps and Improve Insulation

Many rental homes lose energy through gaps and poor insulation. Use weatherstripping or silicone sealant around doors and windows. Add draft stoppers or thick curtains to keep heat in during winter and out in summer.

The DOE recommends sealing air leaks as one of the easiest ways to save energy. It improves comfort and reduces heating or cooling costs.

Switch to LED Lighting and Smart Appliances

Lighting accounts for a significant portion of household energy. Replace old bulbs with ENERGY STAR-certified LED lights. They use up to 75% less electricity and last 25 times longer than incandescent bulbs.

For appliances, look for energy-efficient models when possible. Even small swaps, like an eco kettle or an efficient fridge, can reduce long-term costs.

Unplug and Control Phantom Loads

Many devices consume power even when off. These are known as phantom loads. Use smart power strips or unplug devices like TVs, chargers, and microwaves when not in use. According to the DOE, this simple habit can save households up to 10% on electricity.

Run Appliances During Off-Peak Hours

Electricity costs vary depending on demand. Run high-energy appliances like washing machines, dryers, and ovens outside peak hours (5 pm – 9 pm). Using timers or smart plugs can automate this and optimise savings.

If your rental includes solar panels, schedule energy-heavy tasks during daylight hours to make the most of free solar energy.

Fix Leaks and Install Water-Saving Fixtures

Water conservation is critical, particularly in Gauteng. A dripping tap can waste up to 30 litres daily, according to Nedbank.

Install low-flow showerheads and aerators, and report any leaks immediately to your landlord. Shorten your showers and collect greywater for garden use if allowed. Every drop counts in water-scarce regions.

Optimise Laundry and Dishwashing Routines

Always run full loads to save both water and electricity. Choose cold-water settings for washing clothes—modern detergents work just as well in cool water. When possible, air-dry clothes instead of using a tumble dryer.

For dishwashers, use eco cycles and avoid pre-rinsing dishes under running water. These small steps significantly cut water and energy use.

Use Smart Technology for Better Control

Smart plugs, timers, and thermostats let you control usage remotely. These devices help renters without altering the property infrastructure. Schedule geysers, heaters, or lights to operate only when needed.

Energy tracking apps also visualise consumption trends, helping tenants make data-driven savings decisions.

Work with Your Landlord

Some efficiency upgrades require your landlord’s cooperation. Propose installing a geyser timer, energy-efficient bulbs, or improved insulation. Many landlords agree because these upgrades increase property value.

The DOE encourages renters and landlords to collaborate on energy improvements for mutual benefit.

Take Advantage of Municipal Programs

Several South African municipalities provide water-saving kits or energy-efficiency advice. Check with City Power Johannesburg or Rand Water for available initiatives. These programs may include rebates or free audits to help tenants reduce bills.

Being proactive ensures you benefit from public sustainability programs.

Cultivate Energy-Smart Habits

Behavioural changes matter. Turn off lights when leaving a room, close curtains at night, and limit heater or fan use. Educate household members about efficient energy and water use.

According to Energy.gov, consistent behavioural changes can reduce utility bills by up to 25%. Small daily actions add up over time.

Plan for Long-Term Savings

Renters can still invest in portable solutions like LED lamps, rechargeable solar lights, or small solar water heaters. These pay for themselves within months of reduced bills.

If you plan to rent long-term, consider upgrading appliances or negotiating shared investments in energy-saving installations with your landlord.

Stay Informed and Track Your Progress

Knowledge is power. Stay updated on tariff changes, rebates, and new efficiency technologies. Track your monthly usage to celebrate savings milestones.

Government websites regularly publish energy-saving tips and public notices on municipal tariffs.

Empower Yourself to Save

Reducing water and electricity costs doesn’t require major sacrifices, just smart adjustments. By applying these Top Tips for Renters on How to Reduce Your Water & Electricity Bills, you can take control of your consumption, lower expenses, and contribute to sustainability.

Start small: monitor usage, manage your geyser, seal gaps, and fix leaks. Over time, these actions will make your home more energy-efficient and eco-friendly.

Remember: every kilowatt saved is money in your pocket, and every litre saved supports South Africa’s future.
