Northumberland County lies along Lake Ontario just east of Durham Region, taking in the lakeshore towns of Cobourg and Port Hope, the village of Colborne and a wide stretch of farmland and hamlets farther inland. With fewer than 47 people per square kilometre, much of the county is rural, and that affects everything from which utility a property is connected to, to how long a new service cable has to be.
Several electricity distributors and seven local building departments share the county, and most of its houses were built before 1991. None of that changes the Ontario Electrical Safety Code, but it does change the steps involved in a service upgrade, a renovation or a rewiring project.
The sections below explain how those pieces fit together across the county. For details about a single community, open the Cobourg, Port Hope or Colborne page from the list below.

What Northumberland County Homeowners Should Know
Northumberland County lists building permits, together with zoning and site plan applications, among the local services delivered by its seven member municipalities, so the permit for a renovation is issued by the town or township where the home sits rather than by the County.

Its council is made up of the elected mayors of those seven.

Plumbing permit applications go through the local municipality, where payment is usually made as part of the building permit fee (as of October 2026).

Lakefront, Elexicon or Hydro One: Who Delivers Your Power
Which distributor serves a Northumberland home depends on the address. Lakefront Utilities holds the licence for the Town of Cobourg and the Village of Colborne. Elexicon Energy serves Port Hope, although the Municipality of Port Hope points out that its rural properties are on Hydro One. Hydro One also describes itself as a primary provider in Hamilton Township. For an address in Brighton, Trent Hills, Alnwick/Haldimand or the rest of Cramahe, the company named on the electricity bill is the one to deal with.
That name matters once a project reaches the service entrance: a bigger service, a moved meter or a new underground feed. Lakefront, for instance, handles upgrades and alterations through its Electric Service Change Request, separate from the form used for brand new connections, and Elexicon and Hydro One each run their own processes. On a rural lot the service can also come a long way from the road, overhead or buried, which affects how an upgrade is planned and scheduled.
Permits From the Town, the County and ESA
Northumberland is a two-tier county, so permits are split between levels of government. A building permit for a finished basement or an addition comes from the town or township where the house sits. The County handles plumbing plan review and inspection across its member municipalities, and it issues septic permits everywhere except Trent Hills, which can matter when electrical work is part of a larger rural renovation.
The electrical side is separate from both. The Electrical Safety Authority receives the notification for wiring work and inspects it, whether the house is in Cobourg or on a back road in Alnwick/Haldimand. An owner can file a notification for work in their own home, but a friend or handyman cannot step in, and anyone paid for the job must hold an ECRA/ESA licence. When a Licensed Electrical Contractor does the work, the contractor files the notification, and an ESA Certificate of Acceptance is issued after the work passes inspection.
Older Housing and What It Means for Upgrades
Northumberland's homes lean older than Ontario's as a whole. The County's housing strategy found that almost seven in ten dwellings predate 1991, and in Trent Hills the share is close to eight in ten. Houses of that age were wired for much lighter loads than a modern household puts on them. Depending on the decade, a home may have a 60 or 100 amp service, a fuse panel, or the aluminum or knob and tube wiring that insurers ask about.
In those homes a whole-house electrical inspection is a sensible first step, and its findings decide whether a panel upgrade or rewiring comes next. Rural owners planning a standby generator can have the transfer switch and any panel work designed together. Newer houses raise different questions, usually about room in the panel for an EV charger or a finished basement. Either way, a load calculation shows what the existing service can carry.

Electrical Services in Northumberland County: Common Questions
Which communities does the Northumberland County page cover?
The county has seven member municipalities: Alnwick/Haldimand, Brighton, Cobourg, Cramahe, Hamilton, Port Hope and Trent Hills. Cobourg, Port Hope and Colborne, the village in Cramahe Township, have their own pages, listed above with the services available in each. If you live elsewhere in the county, include your address when you ask for a quote.
How can I tell which utility serves my Northumberland property?
Look at the company name on your electricity bill. In broad terms, Cobourg and Colborne homes are on Lakefront Utilities, Port Hope is served by Elexicon Energy except for its rural area, which is on Hydro One, and Hamilton Township residents are generally on Hydro One. If you are buying a rural property, ask the seller for a recent bill so you know who would handle any service upgrade.
Does Northumberland County issue electrical permits?
No. The County's role covers plumbing review, septic permits outside Trent Hills and entrances onto County roads. Building permits come from your local municipality, and electrical permits, known as notifications, are filed with the Electrical Safety Authority, usually by the Licensed Electrical Contractor you hire.
Should I get an electrical inspection before buying an older home in Northumberland?
With roughly seven in ten of the county's dwellings built before 1991, it is a sensible step for many buyers. An inspection identifies the panel type and capacity, any aluminum or knob and tube wiring, and alterations that do not meet the Ontario Electrical Safety Code, so you can budget for repairs and answer an insurer's questions before closing.
