What London Hydro actually does (and why your bill says "London Hydro" at the top)

Ontario's electricity market is structured very differently from Alberta's, and London Hydro is a textbook example. London Hydro wears two hats at once: it is the distributor that owns the poles, overhead and underground lines, transformers, substations and meters across the entire City of London, AND it is your default supplier under Ontario's Standard Supply Service (SSS) rules. The bill that arrives at your home in Byron, Westmount, Old North or White Oaks covers both jobs.

The per-kWh rate London Hydro charges most residential and small-business customers is set by the Ontario Energy Board (OEB) twice a year in its Regulated Price Plan (RPP), with three structures to choose from: Time-of-Use, Tiered or Ultra-Low Overnight. Long-term fixed-rate retailer contracts are legal in Ontario but a niche market, and signing one does not change the delivery, regulatory or Global Adjustment lines on your bill, only the commodity portion. The wires that bring electricity to your London address belong to London Hydro regardless.

The wires + the default supply
London Hydro (both roles)
  • Owns the wires, transformers, smart meters
  • Restores power after outages (24/7 dispatch)
  • Sends the monthly bill at the OEB's RPP rate
  • Fixed by address: every London property is served by London Hydro
Alternative: licensed retailer
Long-term fixed-rate contract
  • Replaces the commodity portion of the bill only
  • Door-to-door sales banned (ECPA 2010)
  • Delivery + Global Adjustment + regulatory unchanged
  • London Hydro still owns the wires and meter
A London-specific quirk worth knowing

Many older London neighbourhoods (Old North, Old South, Wortley Village, Carling-Talbot) have rear-lot service: the meter and service entry sit on a back-alley pole instead of the street-facing wall. If you are renovating, your electrician needs to flag this early because moving from rear-lot to front-lot service is a London-Hydro-led civil job, not a simple permit swap.

Where London Hydro delivers power

In plain words: if you live or run a business inside the City of London (from Byron and Lambeth in the south-west to Stoneybrook and Masonville in the north, and Argyle in the east), London Hydro is your distributor. There is no overlap and no choice. The boundary follows the City of London's municipal limits exactly.

How London Hydro's charges appear on your bill

An Ontario electricity bill is broken into a handful of distinct line items, all of which appear on the same London Hydro invoice. Unlike Alberta, where the commodity is billed separately by your retailer, in Ontario almost every household sees a single integrated bill where London Hydro acts as both the wires company and the OEB-default supplier.

Electricity (commodity)

The per-kWh rate set by the OEB twice a year in the Regulated Price Plan. You pick one of three structures: Time-of-Use (peak/mid/off-peak), Tiered (low- and high-block) or Ultra-Low Overnight (for EV owners).

Global Adjustment

Funds the difference between the market price and the long-term contracts the IESO signed for nuclear, hydro, wind, solar and conservation. RPP customers see this rolled into the commodity rate; bigger customers see it as its own line.

Delivery

The cost of moving electricity from the IESO-controlled grid through London Hydro's wires to your meter. Includes a fixed monthly service charge plus a per-kWh distribution rate set by the OEB.

Regulatory charges

Small line covering OEB programs, the Wholesale Market Service Rate and a few other system-wide charges. Set by the OEB and applied uniformly across Ontario LDCs.

Ontario Electricity Rebate (OER)

A provincial credit that reduces the pre-tax subtotal by a percentage set by the government (currently around 13 %). Applied automatically to eligible residential, farm and small-business accounts.

HST

The 13 % federal-provincial sales tax applied to the post-rebate subtotal. Cannot be avoided; appears at the bottom of the bill.

London Hydro's delivery rate is approved by the OEB through periodic rate applications under the Renewed Regulatory Framework. Rates are filed publicly on the OEB's eFiling portal and can be examined line by line by any customer or consumer advocate. London Hydro is consistently the lowest cost-per-customer of the twelve largest Ontario electricity distributors in the OEB's benchmarking, a result of its compact urban footprint and disciplined capital programme.

A practical implication: if a licensed retailer offers a low fixed per-kWh rate, you will still pay the same London Hydro delivery and regulatory charges, the same Global Adjustment, the same HST. Switching retailers changes the commodity portion of your bill; switching never changes London Hydro's portion.

Time-of-Use (TOU)

Peak (4-7pm), mid-peak, off-peak. Best for households that can shift heavy use to evenings and weekends.

Tiered

A low block for the first ~600 kWh per month (residential), a higher block above. Best for steady, modest users.

Ultra-Low Overnight (ULO)

Very cheap from 11pm to 7am, much more expensive 4-9pm. Best for EV owners or anyone who can charge overnight.

Contact details: two numbers, one utility

London Hydro separates its 24/7 outage and emergency line from its business-hours customer service line. The emergency number is staffed continuously; the customer service number handles billing, moves, account changes and new connections during regular business hours.

For non-urgent questions you can also use London Hydro's online tools: the live outage map, the outage hub, or the My Account portal at https://www.londonhydro.com. London Hydro consistently ranks among the most cost-efficient distributors in Ontario and benchmarks customer satisfaction every year through the OEB scorecard.

Report a power outage

If your power is out, the fastest path is to call 519-661-5555 or report it on the outage hub. Live restoration estimates are published on the outage map (updated every minute). MyLondonHydro can also push restoration text alerts directly to your phone.

How it works: from your call to power back on
1
You report it

Call 519-661-5555, use the outage hub, or rely on MyLondonHydro text alerts. Have your address and account number ready.

2
Dispatch confirms

The system pinpoints which feeder, transformer or substation is affected and assigns a crew or pole patrol.

3
Crew restores

Estimated restoration time appears on the live outage map. Single faults in London: often within minutes to about an hour. Storm-wide events take longer.

4
Service back

Power is verified at the smart meter. Reset clocks, check freezer contents, and report any damage right away via London Hydro's claims process.

Reliability in plain words

London Hydro reports its reliability performance to the OEB every year in its public scorecard. The two headline metrics are SAIDI (average hours a customer was off in a year) and SAIFI (average number of interruptions per customer per year). London Hydro's results historically sit in line with or better than the OEB's distributor-specific targets, helped by a compact urban network with no significant rural feeders. The full year-by-year scorecard is available on the OEB's distributor-scorecard registry.

Planned outages for maintenance are normally posted at least 48 hours in advance, by mail or notice to affected addresses and on the outage hub. If you depend on medical equipment, register with London Hydro's priority-notification program so you are flagged before any planned interruption.

New connection or service upgrade

For a new build, a service upgrade (e.g. moving from 100 A to 200 A for an EV charger or heat pump), a temporary construction service, or any work that requires changes to the physical wires or meter, you deal with London Hydro. Start at https://www.londonhydro.com or call 519-661-5503. Routine residential connections target the OEB's 5-business-day standard once all conditions are met.

What you'll need before applying
1
Site address

The civic address and the legal description of the lot inside the City of London.

2
Site plan

A sketch showing where you want the meter, service entrance, and run-back to the pole. London also asks about rear-lot vs front-lot service.

3
Service size

The amperage (100 A, 200 A, 400 A…) and voltage you need, signed off by your Master Electrician.

4
ESA permit + certification

An Electrical Safety Authority permit and ESA sign-off once the in-house wiring is done. London Hydro cannot energise until ESA clears it.

Lead time
5 business days (standard)

For routine residential connections once all conditions are met. Complex builds or service upgrades that require civil work can run several months.

Fees
OEB-approved tariff

Fixed component + per-metre charge above the contribution threshold defined in London Hydro's Conditions of Service.

Once the wires are in, your account opens automatically under Standard Supply Service at the OEB's Regulated Price Plan rate. You can switch your RPP structure (Time-of-Use, Tiered or Ultra-Low Overnight) at any time by contacting London Hydro. If you sign with a licensed retailer later, the retailer registers their contract with London Hydro and the commodity rate is replaced on your next bill cycle.

Moving home, transferring or closing a service

In London, the move-in / move-out conversation starts with London Hydro directly, not with a separate retailer. Because London Hydro is the default supplier, it closes the old billing account, sets up the new one, and triggers the final meter read. If you have a licensed retailer contract you also notify the retailer separately so they can transfer or cancel their commodity supply. Most move requests need at least 1 to 2 business days of notice; 5 is safer for end-of-month moves and Western University September turnover.

The move-out steps in order
1
Call London Hydro

Call 519-661-5503 (or use MyLondonHydro online). Give them the move date and your new address.

2
Confirm dates

1 to 2 business days minimum; allow 5 for month-end and student-turnover moves. Same-day service is rare.

3
Final meter read

On the move-out date, London Hydro records the final reading remotely from the smart meter; no in-person visit required.

4
Final bill arrives

London Hydro issues a closing bill for the period up to the move-out date. The new address bill starts under a fresh account.

Staying inside London Hydro

Administrative transfer only. No physical work, no service interruption. Your RPP structure (TOU, Tiered, ULO) carries over by default; ask London Hydro if you want to change it at the new address.

Moving outside the City of London

Opening a fresh account is required at the new LDC. Common destinations from London include Entegrus Powerlines (St. Thomas, Strathroy), ERTH Power (Aylmer, Port Stanley) and Hydro One Networks (rural Middlesex County).

Meters, meter reading and accuracy

London Hydro owns the meter at your address. Since the province-wide smart-meter rollout was completed in 2010-2011, virtually every London residential and small-business address is equipped with a smart meter that supports the OEB's Time-of-Use pricing structure. The meter is the basis for both the consumption side of your bill and the choice between TOU, Tiered or Ultra-Low Overnight RPP structures. London Hydro is also a national leader on Green Button data sharing through MyLondonHydro.

Smart meter (AMI)
Automatic, hourly readings

Every London residential address. Consumption reports back to London Hydro automatically; no action from you, no estimated bills.

Suspect a fault?
Request an accuracy test

London Hydro pulls the meter and tests it on a calibrated bench against Measurement Canada's tolerance.

Green Button
Your own hourly data

London Hydro is a Green Button Alliance member. Download your hour-by-hour data via MyLondonHydro or pipe it into an authorised third-party energy app.

How the accuracy test settles up

If the meter reads outside Measurement Canada's tolerance (typically ±2 %), the test is free and you get a billing adjustment back to the date the fault is presumed to have started. If the meter passes, the test fee is charged to you at the OEB-approved tariff rate.

Note: under AUC Rule 002, Alberta distributors are not required to pay automatic compensation for outages. Damage claims are evaluated case-by-case on negligence.

Compensation and damage claims: the honest version

Ontario has no automatic, statutory compensation scheme for individual customers affected by a power outage. Unlike the UK's Ofgem Guaranteed Standards, the OEB's role is to require London Hydro to report its reliability performance (SAIDI, SAIFI) every year in its public scorecard. Penalties for under-performance flow from the regulator to the distributor; they do not arrive in your mailbox as a credit.

If your fridge or freezer contents spoiled, an appliance was damaged by a voltage surge, or you incurred a clear loss during an outage, you can file a damage claim with London Hydro (Attn: CLAIMS, 111 Horton Street). The claim is evaluated on negligence.

Typically accepted
Distributor at fault
  • +Equipment failure (transformer, network switch)
  • +Crew error during work on the network
  • +Switching incident causing voltage spike
  • +Unplanned, distributor-caused service interruption
Routinely denied
Outside distributor control
  • ×Severe weather (lightning, wind, ice storms)
  • ×Wildlife contact (squirrels, raccoons on lines)
  • ×Third-party contact (vehicle hits pole, dig-in)
  • ×Planned outages notified in advance
Faster path for most losses

Most London home insurance policies cover food spoilage and surge damage at a low excess. If your loss is meaningful, the insurance route is usually faster than a denied utility claim. Keep dated receipts and photos either way. They are the only basis on which any claim can be evaluated.

Regulator and complaint escalation

If you cannot resolve something directly with London Hydro, there is a clear escalation ladder in Ontario. The Ontario Energy Board sits at the top as both the economic regulator and the body that handles consumer complaints; the Electrical Safety Authority covers physical-safety issues.

The escalation ladder
1
Talk to London Hydro customer service

Most issues resolve here. Phone 519-661-5503 (Monday to Friday, 8:30 a.m. to 4:00 p.m.) or use the MyLondonHydro portal.

2
Ask for a formal written response

If the front line cannot fix it, request a written decision in writing. This creates the paper trail needed for the next step.

3
File a complaint with the OEB Consumer Protection Office

The OEB investigates complaints involving Ontario LDCs, retailers and unit sub-meter providers. The service is free.

4
OEB formal hearing or court action

Last resort. For tariff or service-quality issues you can intervene as a registered intervenor in a rate proceeding. For damage claims that are denied, civil court is the final route.

Selectra energy expert answers

Is London Hydro the same company that bills me for my electricity?

Yes, for almost every London household. London Hydro is both the wires company (it owns the poles, transformers and smart meters across the City of London) and the default supplier under Ontario's Standard Supply Service. The default per-kWh rate it charges is the Ontario Energy Board's Regulated Price Plan (RPP), updated every six months. You only see a different name on your bill if you have separately signed a contract with a licensed energy retailer.

I have a power outage in London. Who do I call?

London Hydro directly. Call 519-661-5555. The line is staffed 24/7. You can also track restoration on the live outage map or sign up for outage notifications in your MyLondonHydro account. If you see a downed live wire or smell smoke, call 911 first.

What is the Regulated Price Plan (RPP) and how does it compare with a retailer contract?

The RPP is the OEB-set default electricity rate for most residential and small-business customers in Ontario. It is updated every six months (1 May and 1 November) with three structures: Time-of-Use (TOU), Tiered, or Ultra-Low Overnight (ULO). A licensed retailer instead sells you a long-term fixed-rate contract that locks the per-kWh price for several years. The retailer route does not change London Hydro's delivery, regulatory or Global Adjustment charges on your bill.

Does London Hydro pay compensation if my food spoils during an outage?

Not automatically. Ontario has no statutory automatic compensation scheme for outages (unlike the UK's Ofgem Guaranteed Standards). The OEB requires London Hydro to report its reliability performance (SAIDI, SAIFI) in its annual scorecard, but financial consequences flow to the utility, not to you. You can file a damage claim with London Hydro at the Horton Street office, but claims are evaluated case-by-case on negligence and are routinely denied if the outage was caused by weather, wildlife, third-party contact or planned work.

Can I choose a different electricity distributor in London?

No. Your distributor is determined by your address. Every home and business inside the City of London is served by London Hydro. You can choose your retailer (the energy contract) but not your wires company. Rural Middlesex County addresses fall to Hydro One Networks; St. Thomas and nearby small towns are served by Entegrus Powerlines or ERTH Power.

Who do I call for a new connection or service upgrade in London?

London Hydro. The distributor owns the physical wires and meter, so any new build, service upgrade (e.g. 100 A to 200 A for an EV charger), temporary construction service or panel upgrade goes through them. Call 519-661-5503 (Monday to Friday, 8:30 a.m. to 4:00 p.m.) or apply online at https://www.londonhydro.com. Your electrician will also need to pull an ESA permit for the in-house wiring.

Why does London Hydro have the lowest cost-per-customer among Ontario's large LDCs?

London Hydro is consistently the lowest cost-per-customer of the twelve largest Ontario electricity distributors, according to the OEB's annual benchmarking. Two structural factors explain it: a single municipal boundary with no rural overhang (over 168,000 customers concentrated inside the City of London) and decades of disciplined capital planning. Its 2024 cost-performance result was $735 per customer, putting it in OEB Group 3 (within plus or minus 10 % of predicted costs).
