Why this question doesn't have one answer
An electrical installation in a 30-square-metre studio flat and in a 120-square-metre house is a completely different scope of work - a different number of circuits, a different distribution board, a different length of cables. Before we provide ranges, it's worth knowing what truly affects the final price:
- area and number of rooms - more rooms mean more circuits and longer cable routes;
- scope of work - an installation from scratch in a developer's shell is different from replacement in an occupied flat, where chasing and filling grooves are added;
- standard of fittings - a socket for 15 zł and for 150 zł are different products, and the difference over 40 points in a flat becomes noticeable;
- type of receivers - an induction hob, oven, or car charger require dedicated circuits with a larger cross-section;
- building condition - an aluminium installation without earthing in an old tenement house means more work than ready infrastructure in new construction.
Market ranges for 2026
The amounts below are approximate ranges for installations of average standard (materials + labour, excluding the main building distribution board), in Lower Silesia. The exact price depends on all the factors listed above - therefore, this is a starting point for discussion, not a final offer.
| Type of property | Area | Approximate cost |
|---|---|---|
| Studio flat | ~28-35 m² | from approx. 3 000 to 4 500 zł |
| 2-room flat (M3) | ~45-55 m² | from approx. 3 800 to 5 500 zł |
| 3-4-room flat | ~65-85 m² | from approx. 5 500 to 8 000 zł |
| Detached house | ~100-150 m² | from approx. 9 000 to 16 000 zł |
Replacing an installation in an occupied flat (chasing grooves, filling, painting) usually increases these amounts by 20-40%, while an installation in an open shell state - lowers them, as there is no cost of chasing.
What exactly is included in the price
- Materials - cables, junction boxes, fittings (sockets, switches), apparatus in the distribution board (miniature circuit breakers, residual current devices, surge protection) and the distribution board itself;
- Labour - installation of points, laying and connecting wires, assembling and labelling the distribution board, commissioning;
- Chasing and plastering - only for renovations in existing walls, usually charged per linear metre;
- Acceptance tests - insulation resistance, effectiveness of shock protection, RCD operation - a protocol without which acceptance is incomplete.
Standards that increase the price - but protect you
Part of the cost is not a “contractor's whim”, but rather the requirements of standards that have a real safety justification:
- N SEP-E-002 - specifies the minimum number of sockets and lighting outlets per room and the maximum number of receivers on one circuit (e.g., up to 10 sockets or 20 lighting outlets per circuit) - this is what ensures that a proper installation has enough sockets where they are actually needed;
- PN-HD 60364-4-41 - requires residual current devices (RCDs) with a sensitivity of up to 30 mA for socket circuits, and in new residential installations, also for lighting;
- PN-HD 60364-7-701 - in the bathroom, divides the space into zones 0/1/2 and imposes minimum distances for sockets from the bath or shower, as well as the requirement for equipotential bonding;
- PN-HD 60364-5-52 - links the conductor cross-section with protection and receiver power (e.g., an induction hob usually requires a 5×2.5 mm² or 5×4 mm² cable with separate protection).
In short: an installation compliant with standards costs more than a “bare minimum” one, but it's the difference between a home where the RCD actually protects you and one where it only seems to.
How many points does a typical 3-room flat (M3, ~50 m²) have?
For orientation - an illustrative summary of the number of electrical points (sockets, switches, lighting outlets) in a typical flat with a living room with a kitchenette, bedroom, bathroom, and hallway:
| Room | Approximate number of points |
|---|---|
| Living room with kitchenette | 10-14 |
| Bedroom | 4-6 |
| Bathroom | 3-5 |
| Hallway | 2-3 |
In total, a typical M3 comes out to 30-40 points distributed over 10-14 circuits - and it is this number, not the square footage itself, that most strongly determines the price.
How to reduce costs without compromising safety
- Do not skimp on the number of circuits - adding another socket to an existing circuit is cheap, but an overloaded circuit is the most common cause of tripped breakers;
- Choose mid-range fittings - the price difference between an economy and a premium series for 40 points can reach several hundred zlotys without affecting safety;
- Plan renovations in stages - replacement can be divided into rooms instead of doing the entire property at once;
- Spread payments into instalments - larger works can be split into 0% instalments instead of paying a lump sum.
Fair estimate before work: instead of guessing by square footage, describe your apartment in the installation creator - you'll see price ranges broken down into material and labour, even before you book a visit - or go straight to the online creator. If you prefer a visit, you'll get the same quote via online booking.
