Gas Line Repair in London, OH
48% of households in London take mains gas. Two things follow: there is a buried line on the property, and somebody other than you is responsible for part of it.
Read this first
A buried service line and a meter sit on most properties in London, where 48% of homes are on mains gas. Federal rules end the utility's service line at the meter outlet, so everything downstream of the meter is the owner's to maintain and repair.
Source: US Census Bureau, American Community Survey table B25040; the service line boundary is 49 CFR § 192.3.
If you smell gas right now
Leave the building on foot. Do not use a phone or a light switch inside. Call 911 and your gas utility from somewhere else, and do not call us — we are a referral service, not an emergency line. The full list, in order.
How London is supplied
Under 49 CFR § 192.3, a service line ends at "the outlet of the customer meter or at the connection to a customer’s piping, whichever is further downstream". Upstream of the meter is the operator’s regulated line. Downstream is customer piping, under local code.
That is where the regulated line stops. Who pays is a separate question set by tariff and state regulation, and it is worth asking your utility rather than assuming.
| Households in London | Share |
|---|---|
| Utility (mains) gas | 48% |
| Bottled or tank propane | 15% |
| Electricity | 31% |
| Fuel oil and kerosene | 4% |
| Wood and everything else | 2% |

What B25040 measures is the heating fuel, not the connection. It is the closest published proxy for whether there is a buried service line here, and it is a proxy. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across Ohio as a whole, 62% of households are on mains gas and 5% on tank propane. London sits 14 points below the state on mains and 10 points above it on propane. Averages are where this kind of difference disappears. The figures on this page are the town’s own for that reason.
Before anyone digs on the property
The single most dangerous thing most people will ever do to a gas line is put a spade through it. PHMSA calls excavation damage the leading cause of pipeline incidents; 8-1-1 is a nationwide toll-free number to call before any excavation, and calling it gives a 99 percent chance of avoiding an incident.

What to ask whoever quotes it
Ask what they will do about the existing load. Adding an appliance changes what the existing pipe has to deliver, and sizing is a calculation against the whole system rather than the new run alone.

Checking a plumber in Ohio
Ohio licenses are issued by the Ohio Construction Industry Licensing Board, Department of Commerce, which publishes a public search you can use before work begins. Ohio licenses commercial plumbing contractors at state level; residential-only work is generally regulated locally.
Gas work is separately permitted and separately licensed in most jurisdictions, so ask specifically about gas rather than plumbing in general.
For repair work, not for a suspected leak.If you can smell gas, leave and call 911 or your utility from outside; this is the wrong number for that. For everything else — a line, a meter, an appliance connection — we will route you to a contractor covering your area, free of charge to you. Gas is one part of what London calls us about.
