Boosting your home’s Energy Performance Certificate (EPC) rating doesn’t always require major renovations. Minor upgrades can deliver noticeable improvements, reduce energy bills, and increase your property’s appeal. For homeowners and landlords, these small changes often provide the biggest return on investment.

1. Draught Proofing and Sealing Gaps
Air leaks are a common source of energy loss:
Seal gaps around doors and windows with weatherstripping or caulking
Install draught excluders under doors
Check loft hatches and utility openings
These minor fixes can improve heat retention and EPC ratings significantly. Book a professional check for hidden drafts:

2. Upgrade to Energy-Efficient Lighting
Lighting is a simple, low-cost improvement:
Replace old incandescent or halogen bulbs with LEDs
Focus on high-use areas such as kitchens, living rooms, and hallways
Energy-efficient lighting contributes directly to your EPC score and reduces electricity bills.
3. Improve Hot Water Efficiency
Small adjustments can make a big difference:
Insulate hot water pipes and cylinders
Install a thermostatic valve on the hot water cylinder
Use timers to reduce unnecessary heating
These measures are inexpensive and positively affect EPC assessments:
