How Much Does Wiring Replacement Cost?
Replacing wiring in a 2-room apartment costs 150-250 thousand ₽ in 2026 with materials and work. Here is the exact breakdown and a calculator.
📐 Floor Plan & Rooms
Walls & Partitions

Doors & Windows
Door and window placement, size configuration, opening direction.
Dimensions & Annotations
Automatic dimensions, callouts, text annotations on the plan.
DXF Import
Import floor plans from AutoCAD and other CAD systems via DXF.
⚡ Electrical
Outlets & Switches
Power and low-current outlets, switches, dimmers. GOST/IS symbols.
Lighting
Luminaires, lighting groups, automatic illuminance calculation.
Junction Boxes
Automatic junction box placement, connection count accounting.
GOST/PUE/IS Symbols
Complete library of symbols per GOST, PUE, IS, IEC standards.
🔲 Panels
Auto Panel Assembly
Automatic panel layout: MCBs, RCDs, RCBOs, isolators — from the schematic.
DIN Rails & Busbars
Automatic DIN rail length calculation, auto busbars per phase.
Feeder Topology
Panel hierarchy: main → sub → floor → apartment. Automatic connectivity.
〰️ Cables & Routes
Auto Routing
Automatic cable routing via shortest path with obstacle avoidance.
Cable Sizing
Automatic cross-section calculation by heating, voltage drop, short-circuit current.
Cable Schedule
Automatic cable schedule generation with types, lengths, routes.
Voltage Drop
Voltage drop calculation along the entire chain: from main panel to end consumer.
📊 Calculations
Loads
Pinst, Pcalc, Icalc, cos φ, Kd — automatic per IEC/IS standards.
Short-Circuit
Single-phase and three-phase short-circuit current calculation, breaker verification.
Selectivity
Protection selectivity check: upstream/downstream breaker coordination.
Deterministic Engine
All calculations are deterministic, not LLM. Guaranteed repeatability.

Prices 2026 (RF)
| Item | Price |
|---|---|
| Cable installation | 50-150 ₽/m |
| Chasing | 300-600 ₽/m |
| Socket installation | 350-800 ₽ |
| Panel assembly | 5 000-15 000 ₽ |
| Test protocol | 3 000-10 000 ₽ |
| Materials (2-room) | 80-150 thousand ₽ |
Total for a 2-room apartment
150-250 thousand ₽ with materials and work in 2026. 3-room: 200-350 thousand ₽. House 150 m²: from 400 thousand ₽.
What the price depends on
- Wall material (concrete is more expensive);
- Number of points (sockets, switches);
- Panel complexity and automation;
- Ceiling work;
- Region (Moscow/SPb +30-50%).
