Why Professional ELV Design Matters in Bulgaria
The Bulgarian rules and market conditions that change the ELV design brief.
Cybersecurity Act amendments in force
The NIS2 amendments to the Bulgarian Cybersecurity Act took effect in February 2026. They bring a 24-hour incident reporting duty and personal management responsibility for oversight.
Sofia as a regional hub
Sofia is a primary interconnection point for Southeast Europe, and its data centre market is growing from a small base. Digital Realty bought two Sofia sites in March 2026.
BDS EN 54 and fire safety
Fire detection and alarm products are specified to the BDS EN 54 series where the project calls for them. The fire safety authority reviews the design for public buildings.
Power and VAT
Industrial power is comparatively low-cost in published benchmarks, and colocation services carry standard VAT. Power costs and tariffs should be confirmed with the operator for each site.
Standards
Design Standards & Compliance in Bulgaria
BDS EN 54 series: fire detection & alarm
BDS EN 50173 & EN 50174: cabling
BDS EN 62676: video surveillance
Cybersecurity Act (NIS2 amendments)
EN 50600: data centres
IEC 62443: OT security
Fire safety is reviewed by the national fire safety and civil protection directorate, and building permits are issued by the municipality. Cybersecurity duties under the amended Cybersecurity Act are supervised by the national authority. Confirm the route for each project at the start.
The standards are confirmed for each project. BDS EN 54 is used for fire detection and alarm where specified, and cabling and video standards follow the specification. Final acceptance rests with the authorities and the project's authorised professionals.
