Gas boilers use natural gas from the mains supply, while oil boilers rely on stored heating oil, typically delivered by truck. Oil boilers are often used in rural areas without access to the gas grid. ### How long does a gas or oil boiler installation take? Most standard boiler installations take 1 to 3 days. The duration depends on the complexity of the job, such as whether it’s a like-for-like replacement or a full system upgrade. ### Do I need planning permission to install a new boiler? In most cases, no. Installing or replacing a boiler in the same location does not usually require planning permission. However, listed buildings or major relocations may have special requirements. ### How often should a gas or oil boiler be serviced? Both gas and oil boilers should be serviced **annually** by a qualified engineer to ensure safe and efficient operation and to maintain warranty coverage. ### What size boiler do I need for my home? The right boiler size depends on the number of radiators, bathrooms, and the overall heating demands of your home. A professional installer will calculate your needs to recommend the ideal model. ### Are modern boilers more energy efficient? Yes. Modern gas and oil boilers are **condensing** units that can achieve efficiencies of over 90%, significantly reducing energy bills and carbon emissions compared to older systems.
