District heating in Ireland: available in some Dublin schemes (Poolbeg SDZ, Cherry Orchard, Ballymun, and a handful of new developments) and a few other urban regeneration areas. Connection cost: €3,000–€8,000. Heat is metered and billed monthly. No boiler, no oil tank, no gas connection. Worth it if available: lower running cost than oil, comparable to gas, no maintenance on a heat source. Limited to specific urban schemes in 2026; most Irish self-builds are not on a district heating network. Check with the local authority or developer for availability. If district heating is available at the site, it's a strong option for a new build — the developer typically requires connection as a planning condition.
