Step one: a gas connection
First, check whether the gas network reaches your property and arrange a connection with the network operator, who will install the supply and meter. This can take some time, so start early.
Step two: the installation
Once the meter is in, a Gas Safe registered engineer will typically:
- Run a gas supply from the meter to the boiler position
- Remove the old oil boiler
- Fit a new gas boiler, often a combi or system boiler
- Clean the system and fit a filter
- Commission and register the new boiler

The oil tank
The oil tank and any remaining oil need safe removal and disposal, often by a specialist. Ask whether this is included in your quote, and use up as much oil as possible beforehand.
