Split Metering for Multi-Tenant Properties in Zimbabwe
Split metering means each tenant has their own meter and pays for exactly what they use. One shared meter with the bill divided between tenants is cheaper to install but is the single most common cause of billing disputes on multi-tenant properties in Zimbabwe.
This guide compares the two arrangements honestly, including what each costs and where each causes problems.
Two different things called “split”
The term is used in two ways, which causes confusion.
A split meter is a meter type: the measuring element sits outside, often on a pole, while a small keypad unit inside shows the balance and accepts tokens. It exists to resist tampering.
Split metering is an arrangement: separate metering for each tenant or unit, so each is billed individually.
They frequently go together on multi-tenant properties, because separate metering with tamper-resistant units is exactly what such properties need. Our review of ZESA meter types covers the meter type itself.
Separate meters versus one shared meter
| Separate meters | One shared meter | |
|---|---|---|
| Install cost | Higher | Lower |
| Who pays what | Exactly what each used | An agreed split |
| Dispute risk | Low | High |
| Landlord admin | Minimal | Ongoing |
| Arrears risk | Sits with each tenant | Sits with the landlord |
| Incentive to save | Direct | Weak |
Why shared metering causes disputes
Because the split never matches reality. A flat division ignores that one tenant runs a geyser daily and another is away half the month. Division by room count ignores appliance ownership. Any method produces someone who believes they are subsidising a neighbour — and they are usually right.
There is also no incentive to reduce consumption, because savings are shared while the inconvenience is not. Landlords who have run both arrangements almost always prefer separate metering.
Where a shared meter still makes sense
It is a reasonable arrangement where usage is genuinely similar and small, where the property is short-term or transitional, or where separate metering is not practical given the existing installation. It is a cost and complexity trade-off rather than always the wrong answer.
Where it is nearly always the wrong answer is on a property with a mix of residential and commercial tenants, or where one unit has a large load such as a workshop or a borehole.
What separate metering costs
Each additional metering point involves the meter, the associated protection and switchgear, and the wiring to it. Where the existing installation was never designed for separate supplies, there may also be reticulation work within the property.
Against that, weigh what the disputes actually cost — in arrears, in tenant turnover, and in the landlord’s time. On a property with several tenants the payback is usually quick, and it removes a recurring source of friction permanently.
How to set it up
- Establish the total load. Each unit is assessed and the combined demand calculated with diversity — see load assessments.
- Check the incoming supply is adequate. Separate metering does not increase capacity. If the property’s supply is already at its limit, you may need an upgrade first.
- Plan the reticulation. Each unit needs its own circuit from the metering position.
- Apply. Metering arrangements on multi-tenant properties need to be agreed with the utility rather than assumed — see the application process.
- Complete the internal work. A registered electrician, with a certificate of compliance.
Sub-metering: the arrangement to be careful with
Some landlords install their own sub-meters behind a single utility meter and bill tenants from those readings. It is cheaper than separate utility metering and it does give usage-based billing.
The cautions are real. The landlord remains liable to the utility for the whole account, so a non-paying tenant becomes the landlord’s problem. Recovering charges from tenants depends on what the lease says. And the arrangement must not amount to reselling electricity in a way that falls foul of the regulatory position — worth taking local advice on before setting it up.
Which should you choose?
If you own a property with several independent tenants and intend to keep it, separate utility metering is almost always the better arrangement. It ends the disputes, removes your administrative burden, and moves arrears risk to where it belongs.
If the property is transitional, or the units are small and similar, a shared meter with a clearly documented split may be adequate — but document it in the lease rather than agreeing it verbally.

What to put in the lease either way
Whichever arrangement you choose, the lease should be explicit — most disputes come from things everyone assumed rather than things anyone wrote down.
On separate metering, record which meter serves which unit, that the tenant is responsible for their own supply, and the reading or units at handover.
On a shared meter, record the basis of the split, how and when it is calculated, what happens if a tenant disputes it, and who is responsible if the account falls into arrears. Vague wording here is what produces arguments six months in.
Converting an existing shared arrangement
Retrofitting separate metering to a property wired as one supply is more involved than installing it from new, because each unit needs its own circuit from the metering position. Depending on how the property was wired, that can mean significant work.
It is still frequently worth doing on a property you intend to keep. The cost is once; the disputes are every month.
The sequence is: establish the total load, confirm the incoming supply is adequate, plan the reticulation, then apply. Skipping straight to installing meters without checking the incoming capacity is the common mistake — separate metering divides a supply, it does not enlarge one.
A note on fairness
Where a shared meter must continue, the fairest splits reflect actual usage rather than convenience. Dividing by occupancy or by appliance ownership is closer to reality than dividing by head count, and being seen to have thought about it does more for tenant relations than the precise formula.
