EV charger installation in Varna and up to 75 km around. First we check what supply you have, then what your car can take, and only then do we talk about a charger. We leave you the test reports and a diagram of the new circuit.

Five questions. You’ll see what it comes to in your case: whether the power you have is enough, whether the charger needs to be limited, or whether the shortfall starts before the car even comes into it. The calculation is based on your main breaker and on what your car can take. Skip anything you don’t know — we check it on the site visit.
Data by model from ev-database.org. If in doubt, we check against the registration document and the model.
The portable cable with the control box is fine for the odd top-up when you’re on the road. For everyday charging it isn’t a solution, just a way of putting one off.
The difference isn’t the box on the wall, but what it does with the power: whether it runs on a fixed setting, shows you what you use, or backs off by itself when the house is drawing power. Pick the power you got above and the columns adjust to it.
Answer the questions above and yours will be highlighted here.
Who it’s for: a house with enough power, where nothing changes.
Who it’s for: anyone who wants to see their usage and move it to the cheap rate.
Who it’s for: when there isn’t enough power without load management — the calculator above tells you.
Not sure which one you need? The verdict above tells you: ‘Enough power with load management’ means the third column, and ‘You have enough power’ means the first one will do.Get an exact price
Arguments about price are almost never about the charger itself. They’re about the cable, the trench, the board with no room left. So here we set out what’s included, what’s extra and what might crop up on site — with the operator’s figures, which are public and not ours.
Three things only become visible once the board is opened. Here they are up front, with Elektrorazpredelenie Sever’s prices and timescales — they’re public and don’t go through us.
Prices incl. VAT, per the Elektrorazpredelenie Sever price list valid from 08.07.2026. The connection fee is for the 7–15 kW band; for lower capacity it’s €227.02.
If anything from the right-hand column turns out to be needed, we tell you at the site visit and it goes into the quote as a separate line — it doesn’t turn up at the end.Get an exact price
The most common question on the phone is ‘where will the power come from?’ There’s only one answer: from the output of your meter, not via a cable run down from your flat. From there, everything depends on where that meter is. Choose your situation.
| Service | Price incl. VAT | Timescale |
|---|---|---|
| Unsealing the meter cabinet at the customer’s request | €12.17 | within 7 days |
| Fitting an extra section when there is no room in the board | €42.95 | within 14 days |
| Connection conditions study, up to 6 kW | €34.18 | under Ordinance No. 6 |
| Connection conditions study, 7–15 kW | €37.55 | under Ordinance No. 6 |
| Grid connection, up to 6 kW | €227.02 | — |
| Grid connection, 7–15 kW | €355.86 | — |
These fees are the same for a house and a flat — they’re the operator’s, not our prices. You only pay them if your case calls for it. Our quote is separate and comes after a site visit.

Four things we do that most don’t. And five you can’t see once the installation is done — which is exactly why they get skipped. Click an item in the list to see where it sits in the drawing.
Type 2, seven pins. The two amber ones are the signal pins. Signal pins are shorter than the power pins. If you unplug under load, the signal connection breaks first, the charger cuts the current, and only then do the power contacts separate. That’s why there’s practically no arcing. Earth connects first and disconnects last.

The two routes differ in who waits for whom. In a house, you wait for us — and not for long. In a block of flats, we both wait for the owners’ meeting, and our part takes a day or two once it says ‘yes’.
Either way, the first step is the same — the photos. Everything else follows from them.Get an exact price
Not necessarily. 7.4 kW single-phase over eight hours at night gives about 344 km — enough for almost anyone's daily driving. You need three-phase if your car accepts 11 kW and you want to use it, or if the house is already close to its limit.
Not if the charger has load management: it measures what the house is drawing and throttles back instead of tripping the main breaker. Without load management it depends on your main breaker and your heating — the calculator works it out for your home.
Usually not. Household customers pay for electricity per kilowatt-hour, not for contracted capacity, so an increase is a one-off fee with no monthly charge afterwards — €227.02 to €355.86 on the grid operator's price list. Load management comes first; an increase only when the real simultaneous load calls for it.
Not if your agreed supply capacity and number of phases stay the same — since 2026, Art. 7a of Ordinance No. 6 explicitly exempts a charger for your own use at an existing property. Permission is needed when you go from one phase to three or raise the capacity on your account.
If the cable or the board passes through common areas — yes, by a majority of over 50% of the ownership shares under Art. 17(2)(6) of the Condominium Management Act, in force since 29.09.2023. Before that it was treated as an extension and in practice needed almost unanimous consent. If the parking space is a separate property with its own title deed and everything stays within its boundaries, no decision is needed.
It can — Bulgaria has no ‘right to charge’ like the one in Germany and Austria. A decision can be appealed to the district court within 30 days under Art. 40 of the Condominium Management Act, but overturning it isn't the same as permission: you need a new, properly convened meeting. In practice we haven't come across a single refusal — people get stuck on the power capacity, not on the meeting.
At 7.4 kW — eight hours overnight for about 344 km, and a full 60 kWh battery in about eight hours. At 11 kW — full in six. At 22 kW — in under three, but only if the car accepts 22, and few do: the Renault Zoe and Megane as standard, the BMW iX and Volvo EX30 as a paid option.
Because overnight 11 and 22 kW don't add a single kilometre over 7.4. The battery fills up completely with all three — the more powerful one just finishes earlier and then sits idle. You'd be paying for speed you don't use, and hardly any car accepts it.
For an occasional top-up, yes — not every day. A socket is made for short peaks, not eight hours at full current — it heats up at the terminals. It also wastes more: through a socket about 84% of the electricity you pay for ends up in the battery, through a charger about 89%. And there's no dedicated circuit, no DC leakage protection and no locking.
No. At 7.4–11 kW the battery charges at 0.1–0.2 C — well below the level that stresses the cells. ‘Up to 80%’ is for long periods of standing: if the car will sit for weeks, keep it at around 40–60%. For everyday use, charge as much as you need.
At night, 100 km takes about 15.5 kWh from the grid, including charging losses. On the Elektrorazpredelenie Sever night tariff from 01.07.2026, that works out more than six times cheaper than petrol for the same distance. The night tariff is 40% cheaper than the day rate, and switching to day/night metering is free on request.
If you drive over 10,000 km a year, it pays for itself in a year and a half to two years compared with public charging, where a kilowatt-hour costs three to five times as much as the night rate at home. Below 5–6 thousand km a year the case is weak, and we'll tell you so honestly: then a cheaper charger with a fixed current is enough.
In a house — one day, including digging a trench in the garden in normal ground. In a block of flats the work itself takes one to two days; the wait is for the owners' meeting, not the cable. The quote comes within 24 hours of your photos.
A test report with the actual measured values — insulation, earth rod, RCD trip current and trip time. A single-line diagram of the new circuit. An installation passport with the photos. A warranty card with the registered serial number and 24 months warranty on the installation.
Yes, we'll fit yours too. We check one thing before quoting: whether it has built-in DC leakage protection to IEC 62955. That decides whether the board needs a Type A RCD or the much more expensive Type B.
