Home Rewiring Cost in Prague: 2026 Guide for Expats

Home rewiring in Prague typically costs between 45,000 and 180,000 Kč for a standard apartment, depending on the size of the property, the complexity of the existing wiring, and the materials used. If you live in an older Czech building — and many expats in Prague do — outdated aluminium wiring is one of the most common and most urgent issues you'll face. This guide breaks down what full rewiring involves, what it costs in 2026, and how to find a qualified electrician in Prague who speaks English.

Whether you've just bought a panelák flat from the 1970s or inherited a pre-war apartment in Vinohrady, understanding the rewiring process before you start will save you money, stress, and potential safety hazards.

Why Homes in Prague Need Rewiring

A large portion of Prague's housing stock was built between the 1930s and 1980s. Many of these properties still have their original electrical installations — and that's a problem. Here's why rewiring becomes necessary:

• Aluminium wiring: Most Czech panel buildings (paneláky) built before 1990 used aluminium conductors. Aluminium oxidises over time, creating loose connections and fire risks. Modern Czech electrical standards require copper wiring for new installations.
• Undersized circuits: Older flats were designed for a few lights, a fridge, and a TV. Today's households run washing machines, dishwashers, electric ovens, air conditioning, and multiple high-draw appliances simultaneously. The original wiring simply can't handle it.
• No earth (ground) wire: Many pre-1990 installations in Czech Republic used a two-wire system with no protective earth conductor. This is a serious safety concern with modern appliances.
• Outdated fuse boxes: Old porcelain fuses or early MCBs (miniature circuit breakers) don't provide the same protection as modern RCD-equipped consumer units.
• Insurance and revision reports: In Czechia, your home insurance may require a valid revizní zpráva (electrical revision report). If your wiring fails the inspection, your insurer can deny claims.

If any of these apply to your home, a full or partial rewire is not just an upgrade — it's a safety necessity. Always consult a qualified electrician to assess the condition of your wiring before making decisions.

Home Rewiring Cost in Prague: 2026 Price Breakdown

Rewiring costs in Prague vary significantly based on flat size, wall type, number of circuits, and whether you're doing a full gut renovation or rewiring alone. Here are typical 2026 price ranges:

By apartment size

• 1+kk / 1+1 (studio/one-bed, ~30–45 m²): 45,000–80,000 Kč
• 2+kk / 2+1 (two-bed, ~50–65 m²): 70,000–120,000 Kč
• 3+kk / 3+1 (three-bed, ~70–90 m²): 100,000–160,000 Kč
• 4+ rooms or houses (90+ m²): 140,000–250,000 Kč or more

By individual cost components

• Electrician labour: typically 450–700 Kč per hour in Prague (2026 rates)
• New consumer unit (rozvaděč): 8,000–20,000 Kč including installation
• Cabling per circuit: 2,500–5,000 Kč per circuit (materials + labour)
• Socket and switch points: 800–1,500 Kč per point installed
• Chasing walls (sekání): 200–500 Kč per linear metre, depending on wall material (brick vs. concrete panel)
• Plastering and making good after rewire: 15,000–40,000 Kč (often quoted separately)
• Revision report (revizní zpráva): 2,000–5,000 Kč

These are market ranges and your actual cost will depend on your specific property. Concrete panel walls in paneláky are harder to chase than brick, which increases labour costs. Conversely, if you're doing a full renovation and walls are already stripped, the electrician's job is easier and cheaper.

Important: Prices vary by location too. Electricians in central Prague (Prague 1–3) may charge 10–20% more than those in outer districts like Prague 9 or 13. Always get multiple quotes to compare.

What Does a Full Home Rewire Involve?

If you've never been through a rewire, here's what to expect step by step:

1. Initial assessment: An electrician inspects the existing installation, counts circuits, and identifies the scope of work. They should provide a written quote detailing every element.
2. Planning the layout: You agree on the position of all sockets, switches, and light points. This is your chance to add extras — USB sockets in the kitchen, dedicated circuits for an electric oven or air conditioning unit, smart home pre-wiring.
3. Power disconnection: The flat's power is disconnected from the main supply. During the rewire (typically 3–7 days for an apartment), you may not have electricity.
4. Chasing walls: New cable channels are cut into walls and ceilings. This is the messy part — expect significant dust and debris.
5. Running new cables: Copper cables (typically CYKY-J in Czech standard) are laid in the chased channels and connected to a new consumer unit with RCD protection.
6. First fix testing: The electrician tests all circuits before walls are closed up.
7. Plastering and finishing: Channels are filled, walls are made good. This may be done by the electrician or a separate plasterer.
8. Second fix: Sockets, switches, and light fittings are installed. Final connections are made.
9. Revision report: A certified revizní technik (revision technician) inspects and tests the completed installation and issues a revizní zpráva. This document is essential for insurance and for selling the property later.

The entire process for a typical two-bedroom Prague flat takes 5–10 working days, though this can extend if wall repairs and painting are included.

Partial Rewire vs. Full Rewire: Which Do You Need?

Not every home needs a complete rewire. Here's how to decide:

Full rewire is recommended when:

• The property has aluminium wiring throughout
• There is no earth (ground) conductor
• The fuse box is outdated with no RCD protection
• You are doing a major renovation anyway (kitchen, bathroom, full gut)
• The existing revision report has failed or expired and issues are widespread

Partial rewire may be sufficient when:

• Only one or two circuits are problematic
• You need to add circuits for new appliances (e.g., induction hob, heat pump)
• The main wiring is copper and in good condition, but the consumer unit needs upgrading
• You want to add sockets or move switch positions without replacing all existing cables

A partial rewire typically costs 15,000–50,000 Kč depending on scope. Always have a professional assess what's needed — don't assume a partial fix is enough if the underlying wiring is aluminium or damaged.

How to Hire an Electrician for Rewiring in Prague

Hiring the right electrician for a rewire is critical — this isn't a quick repair, it's a major project that affects your home's safety for decades. Here's what to look for:

Qualifications to check

In Czech Republic, electrical work is a regulated trade (řemeslná živnost). An electrician performing a rewire should hold appropriate qualifications under Czech standards. You can ask to see their trade licence (živnostenský list) and verify their IČO (company registration number) on the official Czech business register at ares.gov.cz.

The person who issues the final revision report (revizní zpráva) must be a certified revision technician — this is a separate qualification from the electrician who does the installation work.

Questions to ask before hiring

• Can you provide a detailed written quote with a breakdown of labour, materials, and timeline?
• Will you handle the revision report, or do I need to arrange that separately?
• What type of cable will you use? (CYKY-J is the Czech standard for fixed installations)
• Do you have liability insurance (pojištění odpovědnosti)?
• Can you provide references or photos from similar projects?
• Will the price include making good the walls, or is that separate?

Red flags to watch for

• No written quote — only a verbal estimate
• Unwillingness to provide their IČO or trade licence details
• Wanting full payment upfront before any work starts
• Suggesting they can skip the revision report to save money
• Significantly lower price than other quotes (could mean cutting corners on materials or not using copper cable)

For expats who don't speak Czech, finding an English-speaking electrician can be challenging but is worth the effort for a project this complex. Clear communication about socket placement, circuit design, and timeline is essential.

Permits and Regulations for Rewiring in Prague

A straightforward like-for-like rewire inside your flat generally does not require a building permit in Czech Republic. However, there are situations where permits or approvals may be needed:

• SVJ approval: If you live in a bytový dům (apartment building) managed by an SVJ (společenství vlastníků jednotek), you may need to notify or get approval from the SVJ before work that involves noise, dust, or changes to shared infrastructure (e.g., the main distribution board in the basement).
• Increasing the main breaker size: If your rewire requires a higher amperage connection from the distribution company (e.g., going from 25A to 32A three-phase), this requires an application to the local energy distributor (PREdistribuce in Prague).
• Listed buildings: If your building is a cultural monument (památka), any visible changes — even internal — may need approval from the heritage authority.

For specific legal requirements that apply to your situation, consult with your electrician and, if necessary, a local building advisor. Rules can change, and enforcement varies by district.

Tips to Reduce Your Rewiring Costs

Rewiring is expensive, but there are practical ways to keep costs reasonable:

• Combine with a renovation: If you're already gutting the kitchen or bathroom, having the rewire done at the same time avoids paying for wall chasing and plastering twice.
• Plan socket and switch positions carefully: Changes after walls are closed cost extra. Spend time on the layout before work starts.
• Get at least three quotes: Prices vary considerably between electricians in Prague. Comparing quotes helps you understand fair market rates.
• Buy your own sockets and switches: Electricians typically mark up fittings. If you buy your own ABB, Schneider, or Legrand switches, you can save 20–30% on materials (but confirm with your electrician first).
• Schedule in low season: Autumn and winter (October–February) tend to be quieter for construction trades in Prague. You may get better availability and sometimes lower rates.
• Don't over-specify: You probably don't need a dedicated circuit for every room. A good electrician will design an efficient layout that meets safety standards without unnecessary complexity.
