How Much Does House Rewiring Cost Per Room in Prague?
House rewiring cost per room in Prague typically ranges from 8,000 to 25,000 Kč, depending on room size, the number of circuits, socket and switch count, and whether walls need chasing or restoration. A full three-bedroom flat rewire usually falls between 60,000 and 150,000 Kč including materials, labour, and the mandatory revision report (revizní zpráva) at the end.
If you're an expat living in a pre-1990 Czech apartment — especially one of Prague's ubiquitous panel buildings (paneláky) — rewiring isn't just an upgrade, it's often a necessity. Aluminium wiring from the socialist era was designed for far lower electrical loads than modern households demand. This guide breaks down exactly what you'll pay per room, what drives the price up or down, and how to avoid common mistakes when hiring an electrician in Prague.
Per-Room Rewiring Prices: What to Expect in 2026
Electricians in Prague generally quote rewiring either per room, per circuit point, or as a fixed project price. Here's what per-room pricing typically looks like:
- Small room (bedroom, study): 8,000–15,000 Kč — typically 3–5 sockets, 1–2 light circuits, minimal chasing
- Living room: 12,000–20,000 Kč — more sockets, possibly TV/ethernet points, overhead and wall lighting
- Kitchen: 15,000–25,000 Kč — dedicated appliance circuits (oven, dishwasher, hob), higher amperage requirements, more socket runs
- Bathroom: 10,000–18,000 Kč — waterproof zoning requirements, fan extraction circuit, heated towel rail, sometimes underfloor heating connection
- Hallway/entrance: 5,000–10,000 Kč — typically fewer points but may include the main consumer unit (rozváděč) location
These ranges include labour and standard materials (copper cabling, sockets, switches, junction boxes). They do not include wall plastering and repainting after chasing — that's a separate trade and typically adds 3,000–8,000 Kč per room.
Consumer Unit (Rozváděč) Replacement
Almost every full rewire requires a new consumer unit. In Prague, expect to pay 8,000–20,000 Kč for the unit itself plus installation, depending on the number of circuits and whether you need a three-phase (třífázový) supply. Older Czech flats often have single-phase 25A supplies, which may be inadequate for modern kitchens with electric ovens, induction hobs, and air conditioning.
What Drives Rewiring Costs Up or Down?
The per-room ranges above are broad because several factors move the price significantly:
1. Wall Type and Construction
Prague apartments come in three main construction types, and each affects rewiring cost differently:
- Panelák (prefab concrete panels): Chasing concrete walls is slow and dusty. Some electricians use surface-mounted trunking instead, which is cheaper but less aesthetically pleasing. Expect prices at the higher end of each range.
- Brick construction (cihlový dům): Easier to chase. Most rewiring quotes assume brick. Prices sit in the middle of the ranges.
- Plasterboard/drywall partitions: Cables can be run behind boards without chasing, reducing labour time significantly. Prices at the lower end.
2. Number of Circuit Points
A "room" with 4 double sockets costs less than one with 8 doubles plus USB charging sockets, dimmer switches, and smart home pre-wiring. Be specific about your requirements before comparing quotes — an electrician quoting 10,000 Kč for a bedroom with 3 sockets is not comparable to one quoting 18,000 Kč for 7 sockets with ethernet runs.
3. Accessibility
Ground-floor flats and houses with crawl spaces or accessible ceilings are cheaper to wire. Top-floor flats in buildings without lifts cost more because of material transport. If you're rewiring a family house with an accessible attic, cables can often be routed overhead, reducing the amount of wall chasing needed.
4. Keeping the Old Wiring Live
If you're living in the flat during the rewire, the electrician may need to keep old circuits live while installing new ones room by room. This sequential approach takes longer than stripping everything at once and adds to the total cost — typically 10–20% more than a vacant-property rewire.
5. Three-Phase Upgrade
Many older Prague flats have a single-phase electrical supply. If your rewire includes upgrading to three-phase — common when adding an electric oven, heat pump, or EV charger — you'll need to coordinate with the distribution company (PREdistribuce in Prague). The upgrade itself can cost 5,000–15,000 Kč on top of the rewiring, and the paperwork can take several weeks.
When Does a Prague Flat Actually Need Rewiring?
Not every old flat needs a full rewire. Here are the situations where room-by-room or full rewiring is genuinely necessary:
- Aluminium wiring: Common in Czech buildings built between 1960 and 1990. Aluminium degrades at connection points and is no longer permitted for new installations. If your flat has aluminium wiring, a rewire is strongly recommended.
- No earth (PE) conductor: Very old installations may lack an earth wire entirely, running only live and neutral. This is a serious safety concern, especially for kitchens and bathrooms.
- Fuse box instead of MCBs: If your flat still uses old-style ceramic fuses (pojistky) rather than modern miniature circuit breakers, the consumer unit needs replacing at minimum.
- Frequent tripping or burning smell: These suggest overloaded or deteriorating circuits. Get an electrician to inspect before assuming you need a full rewire — sometimes only specific circuits need replacement.
- Failed revision report: If your electrical inspection (revizní zpráva) identifies critical faults, your insurance may be invalidated until the issues are resolved.
If your wiring is copper, properly earthed, and less than 30 years old, you may only need a partial upgrade — perhaps adding circuits for a new kitchen or upgrading the consumer unit. A qualified electrician can advise after an inspection.
The Revision Report: A Non-Negotiable Cost
After any rewiring work in the Czech Republic, you need a revision report (revizní zpráva) issued by a certified inspection technician (revizní technik). This is separate from the electrician doing the work — the inspector must be independent.
A revision report for a rewired flat typically costs 3,000–6,000 Kč depending on the number of circuits. For a family house, expect 5,000–10,000 Kč.
This document is critical for several reasons:
- Your home insurance company can deny claims if you lack a valid revision report for your electrical installation
- If you're selling the property, buyers and their mortgage lenders may require it
- It confirms the installation meets current Czech technical standards (ČSN 33 2000)
Always confirm that the revision report cost is included or excluded in your electrician's quote. Some electricians arrange the inspection; others expect you to book it separately.
How to Get Accurate Quotes for Room-by-Room Rewiring
The most common mistake expats make is comparing quotes without ensuring they cover the same scope. Follow these steps to get meaningful, comparable estimates:
- Create a room-by-room specification. For each room, list the number of single sockets, double sockets, light switches, light fixtures, dedicated appliance circuits, and any extras (USB sockets, ethernet, dimmer switches).
- Note your wall construction. Brick, concrete panel, or plasterboard — this materially affects pricing.
- Specify whether plastering is included. Many electricians chase walls and leave the making-good to a plasterer. Clarify this upfront.
- Ask about the consumer unit. Does the quote include a new rozváděč? How many circuits? Does it include RCD/RCBO protection?
- Confirm the revision report. Is it included in the price, arranged separately, or not covered at all?
- Get at least three quotes. Prices vary significantly between electricians in Prague — sometimes by 40–60% for the same work.
Ask every electrician for a written quote (cenová nabídka) broken down by room. This makes comparison straightforward and protects you if the scope changes mid-project.
What to Check Before Hiring
Electrical work in the Czech Republic is a regulated trade (řemeslná živnost). The electrician must hold the appropriate trade licence. You can verify a tradesperson's company registration number (IČO) on the official Czech business register at ares.gov.cz. Additionally, ask to see their professional qualification certificate — for electrical work, this is typically a §6 or §8 certification under Decree 50/1978 Sb. (or its successor regulation).
Request references from previous rewiring jobs, ideally in similar property types. A panelák rewire requires different techniques than a brick villa.
Sample Budget: Rewiring a 3-Bedroom Prague Flat
Here's a realistic budget breakdown for a complete rewire of a typical 75 m² Prague flat (3 bedrooms, living room, kitchen, bathroom, hallway):
- 3 bedrooms: 3 × 12,000 Kč = 36,000 Kč
- Living room: 16,000 Kč
- Kitchen: 22,000 Kč
- Bathroom: 14,000 Kč
- Hallway: 7,000 Kč
- New consumer unit: 15,000 Kč
- Revision report: 4,500 Kč
- Plastering and making good: 25,000 Kč
Total estimate: approximately 139,500 Kč (including materials, labour, inspection, and wall restoration). VAT (DPH) at 12% applies to construction work on residential buildings — confirm whether quotes are s DPH or bez DPH.
This sits comfortably within the 100,000–170,000 Kč range that most Prague electricians quote for this type of project in 2026.
