Converting from Oil to Mains Gas
If a gas main has reached your road, moving off oil removes the tank, the deliveries and the sludge problems that come with an ageing oil system.
If a gas main has reached your road, moving off oil removes the tank, the deliveries and the sludge problems that come with an ageing oil system. The heating circuit usually stays; the fuel side is rebuilt from scratch.
Sequence of the work
Gas supply brought in and tested, new appliance sited and flued, heating circuit flushed and reconnected, then the oil appliance decommissioned.
What the old system leaves behind
Oil systems often run hotter and dirtier. A powerflush or at least a thorough chemical clean and a magnetic filter is genuinely warranted here.
The tank
Draining and removing a bunded oil tank is a separate task with its own disposal requirements — worth agreeing before the boiler date.
Questions worth answering first
- Has the gas supply actually reached the property boundary?
- Where would the new boiler and flue sit?
- Is the existing radiator circuit sized for lower flow temperatures?

Plan an oil to gas changeover
Tell us where the meter would go and where the oil boiler sits now and we will map out the practical route.
Questions we get asked
Do I need a new radiator system too?
Not usually, but radiators sized for an oil boiler running hot can be undersized once you run a condensing gas boiler efficiently.
Who brings the gas supply to the house?
The gas network operator handles the incoming service; we handle everything from the meter onwards.
Is finance available on the boiler part?
Finance is available on boiler installations subject to status and the terms set out on our finance page.
