Water account and utility bills in Bulgaria

Everyday life · Last reviewed: 2026-08-24

What ВиК is and why you cannot choose it

Bulgaria's water operators are organised regionally: water supply and sewerage for a province, or a group of provinces, is run by one operator. There is no competition between suppliers in this structure, because a water network is a textbook natural monopoly; laying a second drinking-water main along the same street makes no economic sense. REGULATION takes the place of competition: the price of the service, the quality targets and the general terms of the contract with the consumer are approved by the Energy and Water Regulatory Commission.

For the consumer that is both a constraint and a safeguard. A constraint, because when you are unhappy with the service you cannot say you will move to another company. A safeguard, because every requirement imposed on you has to appear in an approved text; a condition that is not in that text has been imposed unilaterally. The regulator's own news pages record a case in which, following a consumer complaint, a water operator was ordered to remove contract clauses that did not match its approved general terms. In other words, the approved text is a real foothold and not decoration.

The practical conclusion: when a water dispute starts, open your operator's general terms as approved by the regulator before you open an internet forum. Payment deadlines, the reading regime, meter obligations, disconnection conditions and the complaint procedure are all set out there. That text is the common ground binding both you and the operator, and it carries more weight than anything said verbally at a service desk.

The account: whose name it is opened in

As with electricity, water billing runs through an account held in a named person's name. Opening, changing and closing an account follows the operator's procedure; the documents required are typically proof of ownership or of a right of use plus an identity document. If the account in the flat you have moved into still stands in the previous user's name, every bill you pay is legally posted to their account, and the right to dispute consumption stays with them.

One important difference from electricity is the case of MORE THAN ONE USER. Where rights over a property belong to several people, or where the property is used by more than one consumer, the operator opens accounts for all of them on the basis of a document and a reconciliation protocol showing how metered quantities are shared. Where no such protocol exists, the metered quantities are split EQUALLY between the users, until a document proving different shares is produced.

For tenants, practice varies between companies: some open an account for the tenant against a lease, others require an application from the owner. Either way, recording the meter reading in a handover protocol on moving day matters as much as it does for electricity. Water meter readings are in cubic metres and the decimal digits are usually marked in red; write the red digits down too, because a handover reading rounded to a whole cubic metre creates an argument on the very first bill.

Whose duty is the meter: an important and little-known rule

Water meters are measuring instruments and must undergo metrological verification at set intervals. A widespread misconception exists in Bulgaria at this point: that verifying the meter is the owner's job. The State Agency for Metrological and Technical Surveillance states the opposite in its own guidance: all the steps needed to request subsequent verification of water meters used for commercial payments whose verification validity has EXPIRED, and to replace them with new ones where needed, are the duty of the relevant water operator, not of citizens.

The practical value of this rule is considerable, because consumers are sometimes told that their meter has expired, that they must replace it themselves, and that otherwise they will be billed by norm. The right response to such a demand is not panic but a written question: on what legal basis is the demand made, and who carries the verification duty? Asking in writing produces an answer in writing, and a written answer becomes an attachment to any later complaint.

The route is the same when a meter fails or its accuracy is in doubt: a written request. Removing the meter, breaking the seal or moving it is not something a consumer does; those actions fall to the operator, and interfering with a seal has serious consequences. The one check you can run yourself is to close every tap in the home and watch whether the meter still turns. If it does, there is a leak in the installation, and that finding turns your request into a concrete fact.

The reading period and the logic of the bill

Approved general terms set out how a water meter is read: the reading is recorded to an accuracy of one cubic metre, and the reading period may not exceed the term fixed in the general terms or in the contract, with an upper limit of SIX MONTHS. In other words, the operator cannot keep you on estimated bills indefinitely; an actual reading is expected at least once every six months. That ceiling is also the legal limit on the risk of a surprise reconciliation bill building up behind an unread meter.

The same discipline applies as with electricity: period first, then the readings, and only last the amount. A water bill usually shows three services separately: supply of drinking water, removal of waste water, and treatment of that waste water. Where an address has no sewerage connection, that line should not be charged; where no treatment plant serves the area, the same goes for treatment. A charge on your bill for a service you are not connected to is on its own a ground for a written objection.

Where the building difference comes from

Multi-flat buildings have two layers of metering: the MAIN meter at the point where the building connects to the network, and the individual meters in the flats. The sum of the individual meters almost never matches the main one exactly; the quantity in between is known as the building difference and is shared out among the users. That is not a swindle but physics: it arises from common-area use, garden watering, meters read on different days, individual meters unable to register very low flows, and leaks inside the building.

A small difference is normal; a consistently large and growing one signals a problem. Common causes are a dripping valve in the cellar or a common area, a draw-off point with no meter, a faulty or wrongly fitted flat meter, flats left unread for long stretches, and estimated charges in empty flats. If the building manager does not track the difference, it grows quietly across the year and lands in the bills.

There is also a detail about where meters are fitted. If a flat's inlet has more than one branch, for instance where the kitchen and the bathroom are fed from separate lines, each branch needs a meter; fitting one to a single branch means part of that flat's consumption flows straight into the building difference. When you move into a new flat, count how many meters there are and check that all of them appear on the bill.

Connection, leaks and the boundary of responsibility

Connecting a new building to the water and sewerage systems is covered by its own regulation: application, issuing of technical conditions, design and execution run in sequence. This is infrastructure work rather than an account transfer, and it is measured in weeks. Anyone buying a plot to build on does well to check the connection conditions BEFORE the purchase decision, so that one of the largest future costs becomes visible in time.

When a leak appears, the decisive question is where it is, because the boundary of responsibility is drawn from that. Broadly: the stretch from the network to the building connection belongs to the operator, while the installation inside the building belongs to the owners. The exact position of that boundary is defined in the approved general terms, and most disputes begin with that definition going unread. When you spot a leak, photograph it and report it in writing first; an oral report is worth nothing in an argument about responsibility.

Hidden leaks inside a building are particularly expensive, because they enter the bill unnoticed for months. That is why the overnight meter check is valuable: note the reading before bed and look again in the morning. If the figure has risen with no water used, there is a leak in the installation. This simple test finds where thousands of litres a year disappear, especially in older buildings, and puts the billing dispute on a technical footing.

Outages, quality and the complaint route

Planned interruptions are announced in advance by the operator; unplanned ones come from faults and are reported to the fault line. Some regions may see rationed supply in summer, and in those cases the operator's announcement page is the only reliable source. Neighbourhood conversation and social media posts frequently recirculate old notices.

The quality of mains water is monitored regularly and the results are published. If you have doubts about the colour, smell or sediment of tap water, you are entitled to report it in writing and to ask for a sample. In buildings plumbed with old galvanised pipes the source may be the building itself rather than the network; the practical way to tell them apart is to draw water at the same time from the building inlet in the cellar and from the flat.

The order of complaint is clear: a written submission to the operator first, then, if no answer comes or the answer does not satisfy, a complaint to the regulator. The regulator's news pages have published a case where, following a consumer complaint, an operator was ordered to remove clauses conflicting with its approved general terms, so this route is not merely theoretical. Your submission should state the address, the account number, the disputed period and what you are asking for.

What actually reduces water use

The measures that shrink a water bill are usually small and cheap, because most consumption comes from a few points: a leaking cistern, a dripping tap and long showers. A leaking cistern silently sends hundreds of litres a day down the drain, and the way to spot it is to look at the inside of the pan for a permanent thin trickle. Fixing that single fault makes more difference in most households than any water-saving attachment.

Second come flow restrictors on taps and dual-flush cistern mechanisms. They are cheap, simple enough that even a tenant can fit them and take them away on leaving, and they cut consumption without any loss of comfort. Third come habits: full loads in the washing machine and dishwasher, and closing the tap while washing vegetables. All of this is familiar advice; what is specific to Bulgaria is that the building difference can make your savings invisible. Where the building's loss is large, what you save is not fully reflected in your bill.

Personal saving and building maintenance therefore have to move together. A household counting every drop inside its own flat keeps paying a share of the difference all year because of a dripping valve in the cellar. The most concrete item to raise at a building meeting is monthly written tracking of the gap between the main meter and the flat meters; that single practice makes problems visible before they grow.

Detached houses, gardens and second meters

For houses with gardens the arithmetic works differently and two separate questions arise. The first is watering: a garden watered from the mains easily doubles a household's summer consumption, and the increase can also feed into the sewerage line, because in most arrangements that charge is calculated on the volume of water used, while water going onto a garden never reaches the drain. How that gap is treated is defined in the operator's approved general terms; a written question about whether separate metering for irrigation is possible has a direct effect on the summer bill.

The second question concerns properties with their own well or borehole. Using your own source and being connected to the network are not mutually exclusive; where both exist, which water goes where becomes a metering matter. On a property that draws well water but discharges waste water into the public sewer, how the sewerage charge is calculated is a separate rule. In such set-ups it is better to build a MEASURED rather than an estimated arrangement, which shrinks both the bill and future arguments.

For one-off large draws such as filling a pool, establishing a new garden or construction work, it is worth notifying the operator in advance. An unexpected spike triggers an automatic possible-leak or faulty-meter flag in many systems, and that flag can turn into a site visit. Consumption announced in advance simply lands on the bill. A written notification also leaves a document in your own archive explaining why that period was different.

Moving day: the water checklist

Water is the utility most often forgotten in the rush of moving: it is not felt instantly the way electricity is, and its bill is usually smaller. Yet a forgotten water account produces the same problems: paying into somebody else's record, being unable to object, and inheriting a debt. The work on handover day is short and takes ten minutes: find the meter, photograph the reading and the serial number, count how many meters there are, learn where the building's main meter sits, and ask for the latest bill.

Ask three questions the same day. First: are sewerage and treatment charged here, and is the service actually provided? Second: how large was the building difference over the past year and how is it shared? Third: when does the metrological verification of the meters expire? The answers explain in advance why the first winter bill will look the way it does. Someone who knows them is not surprised, and not being surprised is also the best cure for an unnecessary complaint.

If the bill goes unpaid: the cut-off procedure, inherited debt and prescription

So far this article has explained how the bill is put together. The harder question is what happens when it is not paid. With electricity there is an escape route — you can change supplier. With water there is none, because the operator is a regional monopoly and the relationship cannot be moved to another company. The question is addressed directly in the water section of the Energy and Water Regulatory Commission (КЕВР) question-and-answer pages: if a consumer fails to pay an amount due under an issued invoice within the deadline, the operator has the right to TEMPORARILY suspend the provision of water and sewerage services, and that right flows from the general rules of the law of obligations rather than from the company's own discretion.

But „the right exists“ is not the same as „they can cut you off whenever they like“. Suspension is tied to a PROCEDURE, and that procedure is written. The operator must first send an invitation to pay voluntarily, served in the manner set out in the approved general conditions, and all notices and notifications under those general conditions must be in WRITTEN form. The operator must also have informed you in advance both of the amount owed and of the DATE on which the water will be cut. The practical weight of those two sentences is considerable: a cut-off carried out without written notice, or without a communicated date, can be challenged as a procedural breach. Keep the envelope, the date of service and any notice left at your door — if you later argue about whether the cut-off was lawful, those are your evidence.

The second limit, far less widely known, is this: the operator may not suspend the services while the consumer is performing the obligations of an agreed payment arrangement. In other words, the cheapest defence against a cut-off is not denying the debt but requesting an instalment plan IN WRITING and BEFORE the announced cut-off date. Once the arrangement is signed, the route to suspension is closed for as long as you keep to the schedule. Such a request is not made orally; a promise given over the phone by a call-centre agent is not a basis for stopping a disconnection.

Reconnection after a cut-off is likewise neither automatic nor free. The procedure and conditions for restoring supply are written into each operator's approved general conditions, and those texts are published on the regulator's website. The most practical advice in this article is hidden here: read that text once, before you are ever in the situation. Details such as producing proof of payment, filing a written request for restoration and the period within which reconnection is carried out turn into days without water if a household starts learning them on the day of the cut-off.

Inherited debt is a separate trap. Legally the debt belongs to the holder of the account (партида), that is to a PERSON, not to the walls. The operator's records, however, follow the property, and when you take over an account carrying an unpaid balance, that balance will be asked of you. This is why the moving-in checklist item „ask for the last invoice“ is in fact insufficient: what you should ask for is not the last invoice but a written STATEMENT OF LIABILITIES on the account. A photograph of the meter is not enough either — the debt may belong to a period far older than the current reading, and the photograph does not show it.

Finally, prescription. Water charges are legally periodic payments. Under Article 111 of the Bulgarian Law on Obligations and Contracts, claims for rent, for interest and for OTHER PERIODIC PAYMENTS are extinguished on the expiry of a three-year prescription period. In practice this has two faces. On one hand, pursuing a very old claim is contestable. On the other, prescription does not operate automatically: it must be RAISED, and how and at which stage it is raised depends on the procedure under way. So do not treat prescription as a PLAN; know it as a DEFENCE. For old and large debts, a consultation with a lawyer costs less than a self-drafted objection.

How to verify this today

1. 1

   Establish your operator's name and your account number

   They are on the latest bill or in the building manager's records. Because the service is a regional monopoly, the operator is determined by your address.
2. 2

   Read the approved general terms on the regulator's site

   The reading period, meter obligations, the boundary of responsibility and the objection procedure are there. A verbal explanation at a counter does not replace that text.
3. 3

   Check whose name the account carries and what the shares are

   If several people use the property and no reconciliation protocol exists, the quantity is split equally. If your share differs, prepare the document.
4. 4

   Ask when the meter's verification expires

   Arranging verification for meters whose validity has expired is the water operator's duty. If you are told otherwise, request the legal basis in writing.
5. 5

   Run an overnight test

   Note the reading in the evening, use no water overnight and look again in the morning. If the figure has risen, there is a leak, and you hold a concrete fact.
