Electrician for Home Renovation in Prague: What to Expect

Why Electrical Work Is the Backbone of Any Prague Renovation

Hiring an electrician for home renovation in Prague is one of the most critical decisions you'll make during any remodelling project. Electrical work touches every room — new circuits for a modern kitchen, rewired lighting in a living room, upgraded panels to handle today's appliance loads. Get it right and everything else flows smoothly. Get it wrong and you face delays, failed inspections, and potentially dangerous wiring hidden behind fresh plaster.

If you're an expat renovating an apartment or house in Prague, the Czech electrical system has its own standards, inspection requirements, and professional qualifications that differ from what you may be used to back home. This guide walks you through exactly what to expect when working with an electrician during a renovation — from the planning stage through to the final revision report.

How Renovation Electrical Work Differs from Simple Repairs

Calling an electrician to replace a broken socket is straightforward. Renovation electrical work is a different category entirely. Here's what sets it apart:

Scope: A renovation typically involves moving, adding, or removing circuits — not just fixing existing ones. You may need a completely new distribution board (rozvaděč).
Coordination: The electrician must work in sync with other trades — plasterers, tilers, plumbers, and kitchen fitters. Wiring needs to be roughed in before walls are closed up.
Standards compliance: Any significant electrical modification in the Czech Republic must comply with ČSN standards and requires a formal revision report (revizní zpráva) upon completion.
Planning lead time: Unlike a quick repair, renovation wiring needs a plan. Where will sockets go? How many circuits? What amperage for the main breaker? These decisions happen before any cable is pulled.

Understanding this distinction helps you set realistic expectations for timelines, costs, and communication with your electrician.

Planning the Electrical Layout: What Happens First

Before your electrician picks up a single tool, there's a planning phase that most first-time renovators underestimate. This is where you decide the practical details that will affect your daily life for years.

Socket and switch placement

Think about how you actually use each room. A common mistake is placing too few sockets in the kitchen — modern kitchens need dedicated circuits for ovens, dishwashers, induction hobs, and countertop appliances. In Prague apartments, especially older panel buildings (panelák) or pre-war brick buildings, the original wiring often has just one or two circuits for the entire flat. That's nowhere near enough for a modern layout.

A good electrician will walk through each room with you and ask questions:

Where will your desk and computer be? (dedicated socket cluster)
Are you installing an electric oven or gas? (electric ovens need a dedicated high-amperage circuit)
Do you want smart lighting or dimmer switches?
Where will the washing machine and dryer go?
Will you need an EV charger connection now or in the future?

Electrical project documentation

For larger renovations — especially those involving a full rewire or changes to the distribution board — your electrician or an electrical designer may produce a wiring plan. This isn't always a formal architectural drawing; sometimes it's a marked-up floor plan showing cable routes, socket positions, circuit assignments, and breaker sizing. Having this on paper prevents misunderstandings and gives you a reference if issues arise later.

What Does Renovation Electrical Work Typically Cost in Prague?

Pricing for renovation electrical work in Prague varies significantly depending on the size of the property, the complexity of the job, and whether you're doing a partial update or a full rewire. Here are typical market ranges to give you a starting point:

Full apartment rewire (2+kk, roughly 50–65 m²): typically 60 000–120 000 Kč including materials
Partial rewire (single room or kitchen circuit upgrade): typically 15 000–40 000 Kč
New distribution board installation: typically 8 000–20 000 Kč depending on the number of circuits
Hourly rate for an electrician: typically 450–800 Kč/hour, with higher rates common in Prague 1–3
Revision report (revizní zpráva): typically 2 000–5 000 Kč

These are indicative ranges — actual costs depend on cable lengths, the number of new circuits, whether walls need chasing (cutting channels for cables), accessibility, and material choices. Always get multiple quotes before committing. Comparing at least three detailed written quotes is the best way to ensure fair pricing.

Renovation Timeline: When Does the Electrician Come In?

Timing is everything in a renovation. Electrical work happens in two distinct phases, and understanding this prevents the most common scheduling headaches.

Phase 1: Rough-in (first fix)

This is the heavy work. Your electrician chases channels into walls, runs cables, installs back boxes for sockets and switches, and sets up the distribution board. This happens after demolition and before plastering. If you plaster the walls first and then call the electrician, those fresh walls get cut open again — wasted money and time.

Rough-in for a typical Prague 2+kk apartment takes approximately 3–5 working days, depending on complexity.

Phase 2: Finishing (second fix)

After plastering, painting, and tiling are done, the electrician returns to install the visible elements — socket covers, light switches, light fixtures, and any built-in appliances that need hardwiring. This phase is quicker, usually 1–2 days for a standard apartment.

Between these two phases, your electrician might not be on site for weeks. That's normal. The gap is filled by other trades. Good coordination — often managed by a project foreman (stavbyvedoucí) or by you if you're self-managing — ensures the electrician returns at the right moment.

Czech Electrical Standards and the Revision Report

One aspect that catches many expats off guard is the Czech requirement for a revision report (revizní zpráva) after any significant electrical work. This is not optional bureaucracy — it's a document that confirms your new wiring meets Czech safety standards (ČSN 33 2000 series, aligned with European IEC standards).

Why the revision report matters

Insurance: Most Czech property insurance policies require a valid revision report. Without one, a claim related to electrical fire or damage could be denied.
Property sale: When selling a property, buyers (and their mortgage banks) typically ask for current revision reports.
SVJ compliance: If you're renovating in a bytový dům (apartment building) managed by an SVJ (společenství vlastníků jednotek), the building management may require proof that your renovation meets standards.

Who issues the revision report?

The revision report must be issued by a qualified revision technician (revizní technik) — someone holding a specific Czech certification for electrical inspections. This can be your electrician if they hold the qualification, or a separate specialist. Many expats prefer an independent inspector for objectivity, as the person checking the work is not the same person who did it.

Make sure to discuss the revision report with your electrician before work starts. Clarify whether the cost is included in their quote or separate, and who will arrange it.

How to Choose the Right Electrician for Your Renovation

Finding a reliable electrician in Prague — especially one who communicates well in English — requires some homework. Here's a practical checklist:

Check their trade licence (živnostenský list): Electrical work is a regulated trade (řemeslná živnost) in the Czech Republic. The electrician should hold the appropriate licence. You can verify their IČO (company registration number) on the official Czech business register at ares.gov.cz.
Ask about renovation experience specifically: An electrician who mainly does commercial fit-outs or industrial work may not be the best fit for a residential renovation. Ask for references or photos from similar projects.
Request a written, itemised quote: A professional electrician should provide a quote that breaks down labour, materials, and the revision report. Avoid anyone who gives only a lump-sum verbal estimate.
Discuss the timeline upfront: Ask when they can start, how many days the rough-in will take, and when they'll return for the second fix. A good electrician will ask about your overall renovation schedule.
Clarify communication: If you don't speak Czech, confirm that the electrician (or someone on their team) can communicate in English. Miscommunication about socket placement or circuit design leads to costly corrections.
Agree on a contract: For any renovation electrical work over a few thousand crowns, a written contract (smlouva o dílo) protects both parties. It should specify scope, price, payment terms, timeline, and warranty period.

Common Pitfalls Expats Face with Renovation Electricians

After years of connecting clients with tradespeople in Prague, certain patterns emerge. Here are the mistakes to avoid:

Not planning enough sockets

This is the number one regret. Adding sockets during the rough-in phase is cheap. Adding them after walls are plastered and painted is expensive and messy. Plan for more than you think you need — especially in kitchens, home offices, and living rooms.

Hiring the cheapest quote without checking credentials

A suspiciously low quote often means corners will be cut — cheaper cable, fewer circuits, or skipping the revision report. Electrical work is safety-critical. This is not where to save money.

Poor coordination with other trades

If the plasterer arrives before the electrician finishes rough-in, or the tiler covers a wall before cables are run, you'll pay for rework. Establish a clear sequence and communicate it to everyone on site.

Forgetting about the distribution board

Older Prague apartments often have small, outdated distribution boards with porcelain fuses. A renovation is the perfect time to upgrade to a modern board with RCD (residual current device) protection and properly sized MCBs (miniature circuit breakers). Your electrician should recommend this — if they don't, ask about it.

Not getting a revision report

Some electricians will finish the job and leave without mentioning the revision report. You need to proactively request it. Without it, your insurance coverage may be compromised.

What to Expect on Site During the Work

Renovation electrical work is physical and can be noisy. Here's a realistic picture of what happens in your apartment:

Wall chasing: The electrician uses an angle grinder or wall chaser to cut channels for cables. This generates significant dust and noise. If you're living in the apartment during renovation, plan to be elsewhere during this phase.
Temporary power cuts: During the switchover from old to new wiring, parts of your apartment (or the whole flat) will be without power. Your electrician should warn you in advance.
Debris: Plaster dust, cable offcuts, and packaging accumulate quickly. Clarify with your electrician whether cleanup is included or your responsibility.
Neighbour notification: In apartment buildings, noise from wall chasing can disturb neighbours. Check your SVJ's quiet hours (often no noisy work before 8:00 or after 18:00, and not on Sundays). Some buildings require written notification before renovation work begins.
