Most disagreements about a water or power bill are not really about the amount. They are about the fact that nobody can show how the amount was reached.
A metered charge is arithmetic, and it only ever has four parts:
- The previous reading: where the meter stood at the last bill.
- The current reading: where it stands now.
- The units used: the difference between the two.
- The rate: what one unit costs.
Units used, multiplied by the rate. That is the entire calculation. A bill that shows you only the final figure has removed the three numbers you would need to check it.
What a checkable bill looks like
Water · Unit 4B Previous 12, current 18, 6 units × KES 150 = KES 900
Anyone can verify that in ten seconds, including the person who issued it. Compare it with "Water: 900". Same charge, but now the only way to query it is to ask someone to go and look something up, which is exactly the friction that turns a small question into a standing grievance.
How to check yours
- Find the previous reading. It should be on the bill. If it isn't, ask, and ask for it to be shown on future bills rather than told to you once.
- Go and read the meter yourself. Take a photograph with the digits legible. Do this on the same day the bill was raised if you can; a reading taken two weeks later will not match, and that mismatch is not evidence of anything.
- Do the multiplication. If the units and rate are shown and the total doesn't follow, that is a straightforward error worth raising immediately and politely.
- Watch the gap between readings. If last month's "current" is not this month's "previous", a reading has been missed or estimated, and the consumption has been pushed into the wrong month.
Estimated readings are not wrong, but they are borrowed
Sometimes a meter cannot be read, because nobody was home or the box was locked, and an estimate is used. That is normal. What matters is that the next real reading corrects it, so an over-estimate comes back to you rather than quietly staying in the total. A bill that says a reading was estimated is being honest with you. A bill that estimates silently is storing up an argument for whenever the meter is finally read.
If you're the one issuing the bills
The lesson runs the other way too. Showing the derivation costs nothing and removes most of the queries before they are asked. In , a metered charge carries its reading, its rate and its sum onto the bill and onto the receipt, so a tenant asking "why is it this much?" can see the answer without anyone having to look anything up. Fewer calls, and no month where the honest answer is "I'd have to check".
Whatever system you use, the test is the same: could the person paying this bill check it without phoning you? If not, the bill is incomplete.
Reading the meter itself
Most meter arguments start at the glass, not at the bill.
Water meters show a row of digits. On many dials the black digits are whole units, meaning cubic metres, and the red ones, or the digits after a decimal marker, are fractions of a unit. Bills are raised on whole units, so reading the red digits as if they were units produces a figure ten or a hundred times too large. Note the serial number on the face too: in a block, the single most common billing error is a reading taken from the neighbouring unit's meter.
Postpaid electricity meters show a units total, in kilowatt-hours. Some cycle through several displays, including total units, current load and tamper status, so wait for the one labelled as the total reading rather than writing down the first number shown.
Prepaid token meters are different in kind: you buy credit and the meter counts down, so there is no consumption reading for a landlord to bill you from. What you should still be checking is the balance left on the meter when you move in and when you move out, because that credit is worth money and it belongs to whoever paid for it.
Photograph the meter each month, with the digits and the serial legible, on the same date. It takes fifteen seconds and it is the only evidence that survives a disagreement a year later.
What to do when the bill looks wrong
Work through it in this order. Most of it resolves at step two.
- Check the arithmetic. Current minus previous, times the rate. If that does not produce the total, say so immediately and politely, because it is usually a straightforward error.
- Check the continuity. Last month's current reading should be this month's previous reading. A gap means a reading was missed or estimated, and consumption has landed in the wrong month.
- Read the meter yourself, today, and photograph it. A reading now that is lower than the "current" reading on the bill means the bill cannot be right, and that is a fact rather than an opinion.
- Check the period. A bill covering 38 days after one covering 27 will look like a price rise and is not one.
- Check the rate against what you were told. A rate that has changed without notice is a separate conversation from a reading that is wrong, and worth separating.
- Ask in writing, with your photograph attached. Short and factual: the bill says this, the meter reads this, here is the photograph, please check. A written query with evidence is answered; a phone call is remembered differently by both sides.
- Ask for a joint reading if it is not resolved. You and the caretaker at the meter together, same minute, same digits.
If the meter is genuinely faulty, either still moving with everything off or not moving at all, that is a repair, and the period it was wrong for needs a stated basis rather than a guess. Report it the way you would any other repair: in writing, dated, with a photograph. See reporting a repair so it actually gets fixed.
High bill, no obvious cause: what it usually is
Before assuming an error, rule out the ordinary explanations, roughly in order of how often they turn out to be the answer:
- A misread or transposed digit. A charge ten times the usual is a keying error far more often than it is consumption.
- A leak. A running cistern is the classic, and it is silent. Turn everything off and watch the meter: if it still moves, water is going somewhere. A concealed leak in the supply line is generally the landlord's problem, not yours, and finding it early is in everybody's interest.
- A longer billing period, or a catch-up after an estimate.
- A genuine change in the household: visitors, a new appliance, a change in routine.
- A shared or cross-connected meter. If your consumption tracks somebody else's occupancy, the plumbing may not be what the meter labels say.
The charge that is not metered at all
Water and power are metered. The other lines on a monthly bill usually are not, and they are worth distinguishing because they are checked in a completely different way.
Service charge covers shared costs: common-area lighting, the borehole pump, grounds, security, refuse, and maintenance of shared systems. It is not consumption and should not be presented as if it were. What you can reasonably ask is what it covers, how your share was worked out, and whether there is an annual reconciliation between what was collected and what was spent.
Where a block has no sub-meters at all and one bulk bill is divided between units, ask which basis is used, whether equal shares, occupancy or unit size, and whether that basis is stated in your tenancy agreement. A split that changes depending on who is doing the billing is the problem; the particular method matters less.
Common questions
How do I check a water bill in Kenya?
Confirm the four numbers, which are previous reading, current reading, units consumed and rate, and that last month's current reading is this month's previous. Then read the meter yourself, photograph it, and compare. Anything that does not follow is worth raising in writing the same week.
What does an estimated reading mean on my bill?
That nobody could read the meter, so consumption was estimated from your history. That is normal and acceptable provided the bill says so and the next actual reading corrects it. A silent estimate is the one that builds up an argument for later.
Who pays for water lost through a leak?
Generally the landlord where the fault is in the building, such as a failed valve, a cracked supply line or a concealed leak, and the tenant where they caused it. Report it in writing the moment you suspect it, because a delay makes attribution harder and the bill larger.
Can my landlord charge more per unit than the utility does?
Marking the tariff up turns cost recovery into a margin, and whether that is permitted depends on your agreement and the applicable rules. What you can always ask is what rate is being applied and on what basis, and any legitimate administrative cost should appear as its own named line rather than hidden in the rate.
What if my landlord will not show me the readings?
Ask once in writing for the previous and current readings to be shown on every bill. That is a reasonable request, and most landlords meet it. If they will not, take and keep your own monthly photographs. An independent record of your own is what makes a later dispute winnable.
What should I check about meters when I move in?
Read and photograph every meter on the day, with the serial visible, and send the photographs to the landlord or agent the same week. On prepaid meters, record the remaining token balance too. It takes five minutes and prevents the bill for someone else's consumption arriving in week three.
