For homes relying on air-con systems for temperature control, regular filter maintenance improves energy efficiency.

Address insulation concerns

Your property's age can provide insights into the likelihood of proper insulation during construction. Building standards evolve, so examining your loft and walls is advisable. To inspect wall insulation, discreetly create a hole and probe to assess its condition. Note that even recently built houses may lack the minimum loft insulation of 270mm.

Update appliances

Older electrical appliances often exhibit inefficiency in energy consumption. Gradually replacing devices like electric heaters, refrigerators, dishwashers, and air conditioning units can yield long-term savings.

Check for drafts

Windows and doors are common sources of air leaks, even after modernization. Periodically check and replace worn-out window seals and door draught excluders. To identify other drafty areas, use a lit tealight candle near joints, corners, trim work, floors, and around duct outlets, cables, and pipes. An unstable flame indicates gaps, which you can insulate with caulk, sealant, and tape. If needed, seek assistance from a professional handyman.

Change light bulbs

Switching to energy-saving bulbs reduces bills and benefits the environment. If unsure about transitioning the entire house to LED lighting, strategically replace bulbs based on room usage. Consider hiring a reliable electrician for assistance.

Adjusting Small Habits for Energy Savings

Your proactive approach to improving home energy efficiency doesn't end here. Evaluate your daily appliance use and make changes for lasting impact—every small adjustment counts!

Appliances

Kettle – Boil only the water you need for your cuppa, not for a tea party!
Dishwasher – Opt for full loads and use the eco-button. Occasionally hand wash a few dishes to save energy.
Washing machine – If on an off-peak tariff, run it during bedtime. Remember, half-loads use as much electricity as full loads and temperature settings matter.
Microwave – Use it purposefully; avoid unnecessary reheating sessions. Encourage family meals over individual reheats.
Dryer – Dry clothes indoors on radiators or drying racks when possible.

Lighting

Indoors – Turn off unused lights; it's a simple practice many overlook.
Outdoors – Invest in garden sensor lights and solar lights.

Electronic devices

Turn off the TV when not needed; not all devices need to run in standby mode.
Unplug idle devices like computers, TVs, toasters, and coffee makers to cut standby electricity consumption.

Heating

Temperature control – Adjust thermostat settings as needed and close radiator valves in unused rooms.
Insulation – Swap lace draperies for thick curtains in colder months.
Sunlight – Utilize sunlight to boost room temperature on bright, cold days by opening curtains.

There you have it, a straightforward guide on conducting a DIY home energy check and implementing energy-saving habits to make a positive impact at home and on the environment.

Professional Energy Assessment

Home Energy Assessment Once you've completed your DIY assessment, consider bringing in a professional for a more in-depth analysis. Many utilities provide professional energy assessments at no or reduced cost to customers. Your self-assessment will aid the auditor in thoroughly analyzing your home, covering aspects like comfort, indoor air quality, and potential energy and cost savings.

Now the question arrives here is “How to Arrange a Home Energy Assessment”?

If the idea of a home energy assessment has caught your attention, there are various avenues you can explore.

One approach involves having your property evaluated as part of the Green Deal Assessment. This program in the UK is designed to aid homeowners in implementing energy-efficient enhancements to their homes. To qualify for the Green Deal, your property must undergo an assessment conducted by a certified Green Deal assessor.

The assessor will pay a visit to your home, collect information about the property and your energy consumption patterns, and then suggest improvements to save energy. Subsequently, you'll be furnished with a Green Deal advice report, which encompasses an Energy Performance Certificate (EPC) rating indicating your home's energy efficiency, suggestions for enhancements, and an estimate of potential savings on energy bills. This report remains valid for 10 years or until there are alterations to the property that might impact energy usage. The actual reduction in energy bills will hinge on the quantity of energy consumed and the future cost of energy.

Embarking on the Green Deal involves homeowners reaching out to a Green Deal assessor directly or enlisting the assistance of a Green Deal provider in locating an assessor. There might be a fee associated with the assessment, and the assessor is obligated to inform you of this charge beforehand. Throughout the assessment, you may be queried about property ownership or rental status, the age and construction of your home, potential access issues, as well as your energy usage and any existing energy-saving measures.

Post-assessment, you'll receive a Green Deal advice report, offering insights into your property's energy efficiency and recommendations for improvements. The report will also provide an estimate of potential energy bill savings and a verdict on whether the enhancements will eventually pay for themselves through reduced energy costs. As mentioned earlier, the actual savings will be contingent on future energy costs and the amount of energy consumed.

Understanding Energy Performance Certificates and Their Importance

Energy Performance Certificates (EPCs) provide information on a building's energy efficiency, assigning a rating from A to G. Similar to appliance stickers, they indicate how costly it is to heat and light the property, along with estimated carbon dioxide emissions. EPCs are valid for 10 years and include suggestions for improvements to enhance energy efficiency.

EPCs are crucial for property sales or rentals, as they must be available to potential buyers or tenants from the start of the marketing process. An approved domestic energy assessor is required to produce the EPC. For buyers or renters, EPCs facilitate easy comparison of energy efficiency among different properties, also offering insights into potential improvements, costs, and savings.

The certificate highlights energy efficiency improvements, their costs, and potential savings, aiding homeowners in enhancing their property or guiding buyers looking to make improvements. However, the figures provided are for a typical household in that property and are not personalized to individual lifestyles. Implementing recommended improvements may prompt obtaining a new EPC to reflect these changes.

Not all EPCs look the same, and the guide uses a 2017 certificate as an example. Older certificates may differ in appearance, and there is a new format for EPCs in England, Wales, and Northern Ireland. Despite visual variations, the sections and information covered remain identical across regions.
