05 — Site supervision & authorities

We are on site.
And handle the paperwork.

A project is only as good as its execution. That is why, on request, we take on project management and supervision directly on the construction site – we coordinate the contractors, monitor quality, costs and deadlines and are your dedicated contact.

At the same time, we take care of all administrative matters with the authorities, the grid operator and the insurers. You build – we have your back.

11 — Frequently asked questions

Good to
know.

The most important answers at a glance. Your question isn’t here? Just give us a call.

What does an electrical planner do – and do I need one?

An electrical planner designs a building’s entire electrical infrastructure: power supply, lighting, security, communication and building technology. They prepare plans and tenders, compare quotes and supervise execution. For new builds, major conversions and commercial properties, this saves you money, avoids mistakes and gives you a future-proof installation.

How often must my electrical installation be inspected?

In Switzerland, the Low-Voltage Installation Ordinance (NIV) requires periodic inspections. For residential buildings the interval is usually 20 years; for commercial, restaurant and accommodation businesses it is shorter. The grid operator will ask you in writing to arrange the inspection.

A safety certificate is also required when ownership changes if the last inspection was more than five years ago. We are happy to advise you and organise the inspection together with our licensed inspection partners.

Is a solar system worthwhile in the Bernese Oberland?

In many cases, yes. Modern modules work very efficiently in the mountains too, and a heat pump, battery storage or EV can significantly increase self-consumption. Subsidies are also available, such as the Pronovo one-off payment. We will show you what pays off for your building in a personal, no-obligation energy consultation.

KNX or wireless – which smart home is right?

KNX is an open, manufacturer-independent global standard with its own bus cable. It is considered particularly reliable, durable and flexibly expandable – ideal for new builds and complete renovations. Wireless solutions suit retrofits without major work. We advise you independently and find the solution that fits your building and budget.

Do you also handle dealings with the authorities?

Yes. We handle installation notices and connection requests with the grid operator, clarify fire protection requirements with the responsible bodies and submit subsidy applications. You have one contact – we do the paperwork.

What does an initial meeting cost?

The initial meeting is without obligation. We listen, look at your property and show you possible solutions. We discuss any further costs transparently before we start – no surprises.

Which region do you serve?

We are based in Interlaken and serve the entire Bernese Oberland – from Thun and Spiez via Brienz to Grindelwald, Lauterbrunnen and Frutigen. Larger projects can be supported throughout Switzerland on request.
