An on-site survey is sometimes necessary to accurately estimate the costs and practical feasibility of installing a home charger. Below you will find the most important situations in which an on-site survey is recommended or required.

If excavation work is required to lay cables to the charging station, an on-site survey is essential. It is important to determine the most efficient route on site to avoid unexpected costs. This allows a correct price to be drawn up for the excavation work.

For installations where charging points are already present or when a second charging point is added, things can become more complicated. In such cases, there is a risk that we cannot easily branch off from the differential (diff) and may have to provide an expensive 300mA Type-B differential. An on-site survey helps to assess these risks.

If the cabling has to run through a crawl space, the safety of the installers must be assessed. The height of the crawl space, the humidity and any other possible obstacles are taken into account. This ensures that the technician is well prepared and the costs are accurately estimated.

If work has to be carried out at a height of more than 2 metres, for example with a ladder, an on-site survey is often necessary. This will assess whether special equipment, such as a lifting platform, is required or whether a second technician must be deployed for safety reasons.

For installations where the distance between the meter cupboard and the charging point is more than 15 metres, the route must be accurately mapped. A longer cable run involves more risk and can lead to installation difficulties.

When the route for the cabling is complex, for example due to special penetrations, cable entries over or under roofs, or narrow spaces, an on-site survey can be crucial. In this way, potential obstacles are identified in good time and a suitable solution can be found.

In apartments or larger buildings, the situation is often more complex. It may be necessary to branch off from the main cables in the technical room, which may require additional equipment such as junction boxes or a 300mA differential. An on-site survey will help determine whether there is sufficient space and capacity to carry out the installation safely and in accordance with regulations.

In situations where the incoming current exceeds 63A or where the cable section is greater than 16mm², additional measures are often necessary. An on-site survey will help determine the correct methods for installation, for example by checking whether there is sufficient space for an additional fuse box or differential.

In some cases there may be non-compliant situations, such as multiple cable sections in the main differential clamp or insufficient space in the cabinet. An on-site survey helps to identify and solve these potential problems.
