Every home is different, but as a rough guide:

| Like-for-like boiler swap | About a day |
| Combi conversion or boiler move | Two to three days |
| Replacing all radiators | One to two days |
| Full central heating in a typical house | Several days to around a week |
Typical heating job durations
What happens during a full installation
Engineers usually start by lifting floorboards and running new pipework, then fit radiators, install the boiler and controls, and finally fill, flush, test and commission the system. Floors are relaid as each area is finished.
