Gas Line Repair in New London, NH
Tank propane heats 41% of homes in New London. There is no service line here in the federal sense, which sounds like a technicality and is actually the whole difference.
Read this first
No regulated utility service line is involved where the gas comes out of a tank, and 41% of homes in New London run on propane. The tank and the buried line from it are governed by the supply agreement rather than by a meter boundary, which changes who is responsible for what.
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 New London is supplied
Propane changes the ownership question completely. There is no utility that owns a length of it, which means there is nobody else whose problem part of it is.
It also changes the risk in one specific way: propane is heavier than air and collects in low spaces rather than dispersing upward. Basements, pits and crawl spaces are where it goes.
| Households in New London | Share |
|---|---|
| Utility (mains) gas | 3% |
| Bottled or tank propane | 41% |
| Electricity | 7% |
| Fuel oil and kerosene | 40% |
| Wood and everything else | 8% |

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 New Hampshire as a whole, 25% of households are on mains gas and 17% on tank propane. New London sits 22 points below the state on mains and 23 points above it on propane. The state number would tell you something true about the state and very little about here, which is why it is not the number above.
Before anyone digs on the property
Excavation damage remains the leading cause of pipeline incidents according to PHMSA. That is not a fact about pipelines so much as a fact about gardening, and the prevention is one free call to 8-1-1 before the first spade goes in.

What to ask whoever quotes it
Ask how the work will be tested and what happens at the end of it. An inspection on gas work is normal rather than a complication, and a contractor who treats it as one is telling you something.

Checking a plumber in New Hampshire
The authority is the New Hampshire Office of Professional Licensure and Certification, Mechanical Safety and Licensing Board. New Hampshire licenses plumbers but publishes no online licensee search, so verification means contacting the office directly.
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 New London calls us about.
