Which is cheaper to run-a gas fire or a central heating system?

Generally, a gas fire can be cheaper to run than a central heating system, especially if it's used to heat specific areas rather than the entire home. Gas fires typically have lower installation and maintenance costs, and they can provide immediate warmth. However, if you're heating a larger space or multiple rooms, a central heating system might be more efficient in the long run. Ultimately, costs depend on energy prices, the efficiency of the systems, and individual usage patterns.
