Hydro Rates London Ontario: A Complete 2026 Guide

London Hydro customers in London, Ontario can choose Time-of-Use, Tiered, or Ultra-Low Overnight pricing, and the May 1, 2026 update changed only the timing and thresholds, not the rates themselves. For a household using 700 kWh/month, Ontario says the bill impact is about $10.50 to $11.75 depending on when electricity is used, not because the price changed, but because the clock around the price changed.
That's the moment you run into hydro rates london ontario. You open the bill, see a stack of charges, and wonder why the total doesn't match the simple “per kWh” number you had in mind. If you've ever looked at a statement for a suite, a condo, a mixed-use building, or a property with EV charging and thought, “Which plan saves money here?”, this guide walks through that answer step by step.

What You'll Learn About Your London Hydro Bill
The fastest way to get comfortable with a utility bill is to treat it like a map, not a mystery. The envelope or portal screen may look dense at first, but the charges usually fall into a few familiar groups, and once you know what each group means, the total stops feeling arbitrary.
A useful outside comparison is the Tucson energy bill guide, which shows how a bill becomes readable when you separate the fixed pieces from the usage pieces. London's version has its own structure, but the learning method is the same, start with the rate plan, then trace how usage turns into dollars, then ask which parts are controlled by timing, by total consumption, or by property design.
The four ideas to keep in your head
Practical rule: If a charge depends on the meter reading, timing matters. If a charge depends on the property size or service type, equipment and building design matter.
The rest of this article keeps coming back to four anchors. First is rate structure, because hydro isn't just one number. Second is bill anatomy, because each line on a statement tells a different story. Third is plan choice, because the best tariff depends on how people use power in the building. Fourth is cost management, because submetering and leak detection can turn what used to be a shared expense into something you can track, bill, and recover more precisely.
For residents, that means you can look at a bill and tell whether a high total came from usage, timing, or fees tied to the meter itself. For owners and managers, that same clarity is the difference between absorbing utility costs at the property level and recovering them with better measurement. A helpful internal reference on billing mechanics is the current electric rates overview, especially if you're trying to connect published tariffs with a real account statement.
By the time you finish reading, you should be able to open a London Hydro bill and say, line by line, what is driving the total, what can be changed by shifting demand, and what can only be changed by the way the building is metered.
How Ontario Sets Hydro Rates for London Customers
A London homeowner opens a bill and sees one total, but that total comes from several layers. The easiest way to read it is like a store receipt, where the item price, delivery, and taxes each add something different to the final amount. In Ontario, the amount a customer pays is shaped by the provincial rate framework, London Hydro's published pricing, and the way the building uses electricity.

The Ontario Energy Board sets the framework for the default residential pricing options, and London Hydro publishes the customer-facing rates that sit within that framework. On its rate page, London customers can choose Time-of-Use, Tiered, or Ultra-Low Overnight, which are three ways of pricing the same electricity commodity for different usage patterns. For a plain-language overview of the current options, see London Hydro electricity rates. For residents, that distinction matters because the same apartment, suite, or townhouse can cost more or less depending on when the power is used.
Three plans, one commodity
Under Time-of-Use, electricity changes price by the time of day. London Hydro currently shows 9.8¢/kWh off-peak, 15.7¢/kWh mid-peak, and 20.3¢/kWh on-peak, with weekend and holiday off-peak also at 9.8¢/kWh. Under Tiered, the first 600 kWh/month is billed at 12.0¢/kWh, then usage above that level is billed at 14.2¢/kWh. Under Ultra-Low Overnight, the structure shifts more sharply toward night use, with 3.9¢/kWh overnight and 39.1¢/kWh during weekday on-peak hours. The province's launch notice describes ULO as a separate tariff design within Ontario's regulated system, built to reward load that moves into the overnight window. Ontario launches ultra-low overnight electricity price plan
That is why “hydro rate” is really a stack of rate design, delivery context, and billing logic. Two buildings next to each other can end up with different effective costs even if both receive power from the same utility, because one may run elevators, ventilation, and common-area lighting during daytime peaks while another shifts those loads into quieter hours. The published rate is only part of the story.
For owners and managers, the practical question is which plan fits the load profile. A tower with elevators, corridor lighting, tenant suites, and EV chargers often behaves differently from a low-rise building with lighter common-area demand. If the biggest loads can be pushed into cheaper windows, the tariff choice starts to matter in a way residents can see on the bill, and owners can see in recoverable operating costs. A useful internal reference on the rate structure itself is this current electric rates overview, especially if you are comparing published tariffs with a real account statement.
Reading a Residential Bill From Top to Bottom
A residential statement often looks more confusing than it really is. The easiest way to read it is the way you'd read an airline ticket, base fare first, then taxes, then surcharges. The destination doesn't change, but the path from listed price to final total tells you where the money went.
London Hydro's bill structure usually starts with the electricity charge tied to the selected plan, then adds delivery-related and regulatory items, and finally applies taxes. The useful habit is to ask of every line, “Is this based on how much power I used, how the system delivers it, or a separate policy charge?” That question clears up most of the confusion.
A simple bill anatomy
The table below gives a plain-language view of a typical statement shape. The exact labels can vary, but the logic stays the same.
Line Item
What It Covers
Approx. Share
Electricity charge
The energy you used under TOU, Tiered, or ULO
Varies with usage
Delivery charge
Bringing power to the property through the grid and local network
Varies by bill
Regulatory items
Province-linked adjustments and system-related charges
Varies by bill
Taxes
HST on the taxable portion of the bill
Varies by bill
The important point is not the label itself, it's the function of each line. The electricity charge is the primary focus for many, but the delivery side can still matter when a property has a lot of load or inefficient usage patterns. A plain explanation of that charge structure is available in the delivery charge for electricity guide, which is useful if you want to separate “what I consumed” from “what it cost to move it.”
London Hydro also noted that the May 1, 2026 regulated price plan update did not change the prices themselves, only the timing and thresholds. For a household using 700 kWh/month, the expected bill impact is about $10.50 to $11.75 depending on when the power is used. London Hydro regulated price plan changes take effect May 1, 2026
That detail matters because it shows why two bills can differ even when the same house uses roughly the same amount of energy. If the household shifted a portion of use into the cheaper windows, the rate design alone can change the total. If the property has common-area loads or tenant suites, the same logic applies, only on a bigger scale.
Choosing Between Time-of-Use, Tiered, and Ultra-Low Overnight
A property can use the same amount of electricity and still pay very different amounts, depending on when that power is used. That is the part many readers miss. The rate label on its own does not tell the whole story. A plan can look sensible on paper and still work poorly if the building's load profile does not match it.

How each plan behaves
Time-of-Use works like a train fare that changes by departure time. A flexible property can shift some work into cheaper periods and reduce the bill. Tiered is simpler. It works like a staircase, where staying under the threshold keeps the marginal rate lower, and crossing it raises the next slice of usage. Ultra-Low Overnight is built for heavy overnight demand, but it also carries very expensive weekday on-peak exposure, so it only fits cleanly when most of the flexible load really can stay at night. London Hydro's published rates show the spread clearly, especially the gap between 3.9¢/kWh overnight and 39.1¢/kWh weekday on-peak under ULO. London Hydro electricity rates
For a resident, that means the plan choice is less about the headline rate and more about the timing pattern of everyday life. Laundry, dishwashing, ventilation, EV charging, and common-area equipment do not all behave the same way. A building with elevators, hall lighting, pumps, and parking-lot charging has a different shape than a small home with a few flexible appliances. The rate plan has to match that shape.
Which pattern suits which property
A daytime-heavy household usually has limited room to benefit from ULO, because the expensive hours line up with when people are awake and active. A work-from-home family has more control, since laundry, dishwashing, and some charging can move into cheaper periods. An all-electric home with overnight EV charging often has the clearest case for ULO if most of the flexible load can stay overnight. A multi-unit building with elevators, lighting, pumps, and parking-lot charging needs a closer look, because common-area loads may land in the costly daytime windows even when some tenant activity happens overnight.
Decision rule: If most of the load is fixed during the day, ULO can disappoint. If the load is flexible and night-heavy, ULO deserves a closer look.
That rule matters more for properties than for single appliances. Owners often assume that any building with overnight activity will benefit from ULO, yet daytime common-area demand can cancel out part of the savings. In mixed-use and multi-unit settings, the better question is not which tariff sounds cheapest, but how much of the total load can move.
Tiered pricing is often easier to live with when usage is steady and hard to shift. It behaves like a budget that stays predictable until usage climbs into the next band. Time-of-Use can produce better results when people can change behavior, because the property gains by moving flexible loads away from peak periods. ULO works best when the building has a strong night pattern, like EV charging, laundry equipment, or other controllable loads that can wait until overnight.

How London Water Rates Layer On Top of Electricity
A lot of people searching for hydro rates london ontario are also staring at a water bill. The two systems behave differently, and mixing them up leads to bad budgeting. Electricity is mostly about time of use and total kilowatt-hours, while London water adds a fixed connection charge and a block-based consumption charge.

Why the water bill feels more like a tax bracket
The City of London's 2026 water rates include a monthly connection charge ranging from $18.54 for a 16 mm meter to $2,780.93 for a 250 mm meter. Consumption is then billed on an increasing block structure, with the first 0 to 7 m³ at no additional charge, then $2.6404/m³ for usage above 7 m³ up to 15 m³, and $3.3948/m³ above 15 m³ up to 25 m³. City of London water bill rates
That structure is similar to a progressive tax bracket. The first layer is lighter, then the next layer costs more, then the next layer costs more again. If a suite or building uses more water than necessary, the extra gallons don't just add cost, they can push the bill into a more expensive marginal block.
Why that matters for property operators
Leak detection becomes a cost-control tool, not just a maintenance tool. A running toilet, hidden line leak, or slow fixture fault can drive usage up, and once usage crosses into a higher block, each extra cubic metre is billed at the higher marginal rate. For owners, the problem is that water waste often shows up as a shared expense before anyone spots it.
A building with submetered suites can isolate which unit is driving abnormal use. A building without submetering often pays that waste out of the property's operating budget, which means the loss is borne by the owner, not the person or system causing it.
Water losses are easier to stop when you can see them at the suite level.
That's why water and electricity should be read together. One is about timing, the other is about volume and meter size, but both reward clearer measurement. If the goal is lower operating cost, the billing structure is only half the story, the other half is finding the source of the load.
Why Submetering and Leak Detection Change the Math for Buildings
Submetering changes utility spending from a pooled expense into a measured one. That difference sounds small until you manage a building with tenant suites, common-area lights, elevators, pumps, or EV chargers. Once consumption is visible at the unit level, the owner can recover costs more precisely, and once leaks are visible, water loss becomes a fixable problem instead of an invisible drain.

What submetering actually changes
A Measurement Canada-approved electricity submeter gives owners and managers a cleaner split between common-area usage and tenant usage. Suite-level water meters do the same for water, and leak and flood sensors add an early warning layer that can catch issues before they become expensive damage. In practice, that means the building can bill each party on what they used instead of relying on estimates or broad allocation formulas.
The financial effect is straightforward. Bulk utility expenses stop sitting entirely on the owner's top line, disputed or estimated charges drop because the meter data is sharper, and the building gets the interval information needed to see whether a given property leans toward Time-of-Use, Tiered, or Ultra-Low Overnight. For London and Ontario properties, that's not a theoretical benefit, it's the difference between guessing at the tariff and matching the tariff to real load.
A useful companion explanation on suite-level allocation is the sub-metered water guide, especially for owners comparing water recovery methods across a portfolio.
The building owner's problem list
- NOI pressure: Bulk utility bills can compress net operating income when all usage stays on the owner's books.
- Tenant friction: Estimated or blended billing often creates disputes because residents can't see what they caused.
- Hidden loss: Water leaks can run long enough to waste money and create damage before anyone notices.
- Planning gaps: Many teams don't have the metering data needed to choose the right power plan for the building.
Axis Meter Solutions is one option in this space. It provides full-service utility submetering for multi-family, condominium, mixed-use, and commercial properties, including metering equipment, installation, commissioning, tenant billing, and ongoing service under long-term agreements with no upfront capital cost to the owner. It also includes leak and flood detection with water installations, which matters when a small leak can quickly distort a utility budget.
The main lesson is simple. Rate design gives you the price. Submetering tells you who caused the cost. Leak detection tells you where the loss starts.
Practical Steps Owners and Managers Can Take This Quarter
A good utility plan starts with an audit, not a purchase. Owners and managers don't need to solve everything at once, they need to make the next decision with better information than they had last month.
Start by comparing current bills to the published London Hydro rates. Look for obvious mismatches between the selected plan and the actual usage window, and confirm that the billing line items line up with the tariff you think the building is on. If a statement seems off, the problem may be the rate choice, the meter setup, or a billing error.
Then check the load profile. A building with daytime common-area demand, elevators, ventilation, or pumps may not benefit from the same plan as an overnight-heavy building. If you don't have interval data, you're making a tariff decision blind.
A short action list
- Audit the bill: Match each charge to the current published rate structure and verify the meter class, plan, and billing period.
- Test the plan against usage: Don't rely on the tariff name. Compare it to the building's actual timing of consumption.
- Review submetering economics: Ask whether a provider-funded model fits the property, especially if a project can be delivered without upfront capital and on a typical 8 to 10 week implementation timeline.
- Check compliance early: Ontario Energy Board licensing matters for unit sub-metering, so confirm the provider's framework before scope is finalised.
The cheapest project is the one that fits the building the first time.
That last point matters because delays usually come from unclear assumptions, not from the meters themselves. If you know who uses what, when they use it, and how the bill is assembled, the next move gets much easier.
Putting It All Together for Long-Term Cost Control
The cleanest way to think about hydro rates london ontario is as a loop. Rate literacy tells you what you're being charged. Submetering tells you where the charge belongs. Leak detection tells you where waste begins. Ongoing monitoring tells you whether the changes stuck.
That loop is especially useful after you open a bill and see a number that feels too high. Some of that total will be fixed by the rate structure, some of it will depend on when power was used, and some of it can be recovered if the building has better tenant-level measurement. Once those pieces are separated, the bill stops looking like a single expense and starts looking like a set of decisions.
For teams that want a broader maintenance lens, the same mindset shows up in predictive maintenance for electric motors, where monitoring beats surprise failures because staff catch the problem before the cost compounds. Utilities work the same way, the earlier you see the pattern, the more of the expense you can control.
Keep three sources on hand. London Hydro for the current rate tables, the Ontario Energy Board for the regulatory framework, and the IESO for the broader market context. If you manage property, the main goal isn't just reading the bill, it's building a system where fewer costs stay hidden.
