Why Convert To Gas Heating?

Swipe to discover all of the benefits of switching to a natural gas heating system…

Future Proof

Modern gas boilers are ‘alternative fuel ready‘ meaning they will be compatible with all renewable fuel sources added to the gas network in the future, as Northern Ireland transitions towards net zero.

Instant Heat & Hot Water

A gas heating system gives you access to instant heat and hot water. Radiators heat up quickly, while hot water is always available on demand.

Reduce Carbon

Gas remains the cleanest fossil fuel for heating your home. Making the switch to gas from other fuel sources such as oil or LPG will reduce your carbon footprint by up to 50%.

Grants Available

As Northern Ireland transitions towards a net zero future, grant funding is available to help make local homes more energy efficient. We are an official installer for grants under NISEP. Find out more here.

Never Run Out

The gas supply is always open and running to your home, so you never have to worry about running out or placing large and costly fuel orders.

No Hot Water Tank

With access to instant hot water from your gas heating system, there is no need for a bulky hot water tank in your home.

More Efficient

Gas boilers operate at over 90% efficiency, therefore reducing the amount of energy you use and helping you save money on your bills.

Flexible Payments

With gas heating, you can choose to pay how best suits you and your lifestyle. Opt to go pay-as-you-go or in monthly or quarterly installments.

Often, mortgage lenders offer preferential rates to homeowners whose homes have the highest EPC ratings.

Will having gas save me money on my energy bills?

Like all energy prices, gas tariffs can fluctuate. However, a new gas boiler operates at over 90% efficiency and therefore requires less energy to heat your home and hot water, helping to save money on your monthly energy bills. 

Is gas convenient?
