Energy Saving Week 2025: A Smart Guide for NI Homeowners to Reduce Bills & Boost Efficiency

Nov 27, 2025 | News

Energy Saving Week 2025

Energy Saving Week 2025 is here — and it’s the perfect time for Northern Ireland homeowners to take a closer look at how their home uses (and loses!) energy. With rising interest in renewable technologies and new measures announced in the UK Autumn Budget, now is the ideal moment to make your home more efficient, comfortable, and cost-effective.

This guide breaks down everything you need to know — from insulation and smart heating to heat pumps, solar panels, and NI-specific grants.

1. Stop Heat Escaping

Heat can escape through your roof, walls and even your hot water tank — and most homes in Northern Ireland still aren’t insulated to the recommended levels.

Quick wins:

These upgrades keep your home warmer for longer, reduce energy waste and significantly cut heating bills.

2. Be Smart with Your Home Heating

Small changes can lead to big savings:

  • Use thermostats and radiator valves correctly

  • Set your heating to match your daily routine

  • Lowering your thermostat by just 1°C can save £80–£130 per year

  • Electric storage heater settings matter — especially the input/output controls

  • Insulate hot water cylinders for extra savings

Smart heating habits mean you’re only heating what you need — and nothing more.

3. Compare Tariffs & Get Energy Advice

Northern Ireland residents can save money simply by reviewing their energy tariffs.

4. Go Renewable: Heat Pumps & Solar Panels

As Northern Ireland moves toward a low-carbon future, renewable technologies are becoming more popular — and more efficient.

Air Source Heat Pumps (ASHPs)

  • Low-carbon alternative to oil or gas heating

  • Suitable for most NI homes

  • Can save 1,400–3,500kg of CO₂ per year

  • Highly efficient — producing more heat energy than they use in electricity

Solar PV Panels

  • Work even on cloudy days

  • A typical 3.5kWp system saves around 550kg of CO₂ annually

  • Can power your home appliances and even your EV

  • Export tariffs pay you for unused electricity

Best Results? Combine ASHP + Solar

This pairing maximises efficiency, reduces running costs and cuts carbon emissions dramatically — making it the strongest long-term investment for a future-proof home.

5. Grants & Support Available in NI

Northern Ireland has unique schemes separate from GB:

Caveats

Oil-heated home: Based on a typical three-bedroom semi-detached house, with an 85% efficient oil boiler using an average oil tariff over the past 12 months of 5.5/kWh (56p/litre, based on £280 for 500 litres order) and average electricity tariff of 30.8p/kWh; correct as of October 2025.

Gas-heated home: Based on a typical three-bedroom semi-detached house, with an 89% efficient gas boiler using an average gas tariff of 9.0p/kWh and an average of electricity tariff of 30.8p/kWh; correct as of October 2025.

Electric-heated home: Based on a typical three-bedroom semi-detached house, with 100% efficient storage heaters, using an average off-peak Economy 7 electricity tariff of 16.7p/kWh, and peak-rate Economy 7 electricity tariff of 35.0p/kWh; correct as of October 2025.
