Electrical work Vienna a third of it is masonry work.

“Electrical work Vienna, a third of it is masonry work” — the standard is clear: every socket live, every switch working, every cable with a measurement and test record according to ÖVE/ÖNORM E 8001. Electrical installations must not first attract attention when the RCD trips or at the first short circuit — they are a sensitive trade that must be documented by authorised electrical engineers with an installation log and commissioning report. Skyline Bau coordinates this with authorised electrical engineers under § 94 no. 16 GewO from its own network.

How to tell that rewiring is needed

What does electrical work in Vienna cost?

For a complete new installation, the guide value is around 100 to 150 euros per square metre of living space — including cables, boxes, switches, distribution board and RCD protection. That applies to standard situations; much is individual and depends on the existing installation. The exact scope only becomes clear at the site visit, because most of it lies behind the plaster.

Specifics

Electrical installations in existing buildings have their own issues that you need to know about. This is what we pay attention to:

• Classic TN-C earthing (“Nullung”) in Gründerzeit buildings — many Viennese old buildings still have the old protective system without a separate protective earth. It is considered outdated and is replaced during renovation by a modern protective system with an RCD.
• Too few circuits — old-building electrics were designed for completely different loads. Two or three circuits for the whole apartment were normal — today the fuse constantly trips with that.
• Fabric-covered cables — very old installations contain cables with a textile sheath. They are brittle and a safety risk — they need replacing, not patching.
• Surface-mounted or concealed in protected buildings — in protection zones and in buildings worth preserving, not every chasing job is permitted. Then surface-mounted systems or existing conduits are used.
• Risers in apartment buildings — in an owners' association, risers and communal power are a shared matter. Changes require a resolution.
• ÖVE testing obligation — every new or significantly altered installation must be measured by the electrical engineer and documented with a test report. Without this report, the installation cannot be accepted.

Electrical work — in all 23 districts and the surrounding area

We coordinate electrical work throughout Vienna, as well as in Klosterneuburg and the surrounding area of Lower Austria. It is carried out by our licensed electrical engineering partners.

An electrical installation follows clear steps:

Why Skyline Bau for your electrical work in Vienna

We are the building contractor doing the work and coordinate the electrical work through licensed electrical engineering partners. The advantage lies in the interface: when electrics, plumbing, plaster and floor come together, nobody has to mediate between several companies.

• One contractual partner for the whole renovation — even when several trades are involved.
• Fixed price according to ÖNORM B 2110, in writing after the site visit.
• Licensed electrical engineer under § 94 no. 16 GewO, whom we name before the contract is signed.
• Test report and photo documentation of the concealed cables at every handover.
• €3 million construction liability insurance and experience in occupied Viennese apartment buildings.

Materials: cables, switches, distribution boards

Where quality lies in an electrical installation — and where the price differences come from:

Photovoltaics, wallbox, smart home

Electrics today are more than lights and sockets. Three topics that should be considered with a new installation:

• Wallbox — charging an electric car requires a dedicated, adequately sized circuit and usually a special RCD type. Anyone who lays the conduit to the garage now saves chasing later.
• Photovoltaics — the electrical engineer plans the PV system itself; what matters is the connection to the distribution board and the meter replacement. In an apartment building, a system on the communal roof is a matter for the owners' association.
• Smart home — whether KNX bus or a wireless solution: the basic cabling decides what is possible later. A bus system needs to be planned from the start; wireless is easier to retrofit.

Who actually carries out the electrical work

Clarity about who does what: electrical engineering is a regulated trade under § 94 no. 16 GewO. A building contractor may not carry it out itself. We are the building contractor doing the work and coordinate the overall renovation; the electrical work is carried out by our licensed electrical engineering partner, whom we name to you before the contract is signed. We remain your contractual partner — with one fixed price and one warranty for the entire project.

What you receive from us before signing the contract

Four things you hear elsewhere — but not from us

• “Price over the phone” — without a site visit, every phone price is guesswork. We state it after the inspection, in writing.
• “We do everything ourselves” — a building contractor may not carry out electrical work itself. Anyone who claims otherwise is not telling the truth.
• “20-year guarantee” — the statutory warranty is 3 years under § 933 ABGB. Longer promises must be in writing.
• “You don't need a test report” — yes, you do. Without an ÖVE report the installation cannot be accepted and is a problem in insurance matters.

When you do not need us

To be honest: for a single faulty socket or an additional light, call an electrical engineer near you directly — that is faster and cheaper. We are the right address when the electrics are part of a larger renovation and several trades need to be coordinated.

Whether private or commercial — we carry out electrical work in Vienna on schedule and cleanly. Professional electrical work saves time, money and nerves.

what you should know

So that you know exactly what to expect, we answer the most important questions here — honestly and from the practice of a building contractor that does the work itself.

What electrical work do you carry out?

We coordinate the renewal and installation of electrical installations as part of renovations and conversions: new cables, distribution boards, sockets, lighting and connections. Electrical work is a regulated trade — the work requiring a licence is carried out by our authorised electrical partner companies, and we coordinate the overall project.

When do the electrics need renewing?

Signs include: old cables without a protective earth, too few sockets, fuses that often blow, a missing RCD. In old buildings, the electrics are often no longer up to date and are a safety risk. A renovation is the ideal time to renew them.

Is electrical work part of an apartment renovation?

Yes — in a comprehensive renovation the electrics are usually renewed as well, because the walls are open anyway. As the building contractor, we coordinate the electrical partners with the other trades so that everything runs from a single source.

What does electrical work cost in Vienna?

The costs depend on the scope, the number of connections and whether walls have to be opened. After a site visit you receive a binding fixed-price quote.

Electrical installation during old-building renovation: the order in which the work is done

In an old-building renovation, the electrics are not a project of their own but a trade that has to fit into the construction sequence. Anyone who schedules it at the wrong time opens up freshly plastered walls again. The sensible sequence is as follows:

1. Survey the existing installation: the electrical engineer measures the existing installation, checks the protective measure and cable cross-sections and determines whether the supply from the riser is sufficient.
2. Plan: using the furniture layout, circuits, sockets, outlets and network are defined – above all in the kitchen and bathroom, where later changes are most expensive.
3. First-fix installation: chases, boxes and conduits are created before screed, plaster and tiles. Cables on the floor lie on the bare slab and are covered by the insulation.
4. Closing up: chases are plastered, followed by screed, painter and flooring.
5. Second fix and test report: switches, sockets, distribution board and light fittings are installed, measured and recorded.

Most mistakes happen between the second and third steps: if the kitchen is only planned after the first fix, connections are later missing exactly where the appliances stand. How the electrics are embedded in an overall renovation is shown on the page old-building renovation in Vienna.

What is structurally different in the districts

The starting situation differs from building to building. In the Gründerzeit apartment buildings of Favoriten (1100) or Leopoldstadt (1020), the cables usually run in brick walls with timber beam floors above, and the risers are often designed for far less power than today's kitchens need. In the villas and large old-building apartments of Währing (1180) and the 19th district, there are also stucco ceilings and parquet floors that must be protected during installation. In Donaustadt (1220) and Liesing, detached and terraced houses from the 1960s to 1980s dominate; their electrics are younger but rarely offer enough circuits for a heat pump, wallbox or photovoltaics.

Electrical service in old buildings: retrofits and smaller jobs

Not every old-building apartment needs a complete rewiring straight away. Often it is about individual measures: retrofitting an RCD, adding a circuit for the dishwasher, replacing a loose socket or rewiring a room. For a pure fault without construction work – the fuse trips, a light does not work – going directly to an electrical engineer is faster, because no construction coordination is needed there.

An electrical service through us makes sense when chasing, plastering and painting work arise along with the electrics, or when a property management wants to bundle several smaller jobs in different apartments. Then electrical engineers, bricklayers and painters come in a coordinated way, and at the end the wall is closed and painted again – not just the socket wired. For property managers, we document every job with photos and a test record, so that even years later it can be traced what was renewed in which apartment.

Electrical installation in new builds and extensions

In a new build, electrics are cheaper than in an existing building because there is hardly any chasing: conduits and boxes go into the floor slab before concreting or into the wall before plastering. The guide prices are €75 to €140/m² net for the first-fix installation. The most important moment is the foundation earth electrode – it must be laid before the floor slab is concreted and cannot be cleanly added afterwards. It is also worth laying empty conduits now for a later photovoltaic system, a wallbox in the carport or additional network cables: a conduit costs little in the shell, but afterwards it means chasing. Anyone planning an extension should also have it checked whether the existing distribution board and the building connection can still take the new circuits.

Distinction: electrics alone or as part of an apartment renovation

This page deals with electrical work as a trade of its own – with costs, process and interfaces. If the bathroom is renewed, the kitchen replaced and the floor redone at the same time, the overall process is the real topic; then you will find the appropriate planning under apartment renovation in Vienna. There the electrics are one building block, but price and duration depend on the entire conversion.
