Oil vs Gas Boilers: Should You Convert?
Gas is cleaner, cheaper and lower-maintenance than oil — conversion often pays off.
If you still heat with oil, converting to gas (or a heat pump) can cut costs and hassle.
Why gas wins
Natural gas burns cleaner, costs less to run, needs no on-site tank, and powers efficient condensing boilers and combis.
Converting
Conversion involves a gas line, a new boiler and removing the oil tank — often offset by lower running costs and rebates.
Key takeaways
- Gas: cleaner, cheaper, no tank
- Oil: higher cost and maintenance
- Consider a heat pump too
- Conversions can be rebate-eligible
