Why there is no single answer to this question
An electrical installation in a 30-metre studio apartment and in a 120-metre house is a completely different scope of work - a different number of circuits, a different consumer unit, a different length of cables. Before we provide the ranges, it is worth knowing what actually affects the final price:
- floor area and number of rooms - more rooms mean more circuits and longer cable runs;
- scope of work - installation from scratch in a shell state is different from replacement in an occupied flat, where chasing and plastering grooves is required;
- standard of fittings - a socket for 15 zł and one for 150 zł is a different product, and the difference over 40 points in a flat becomes noticeable;
- type of appliances - 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-made infrastructure in a new build.
Market ranges for 2026
The amounts below are approximate ranges for a medium-standard installation (materials + labour, excluding the building's main distribution board) in Lower Silesia. The exact price depends on all the factors listed above - which is why this is a starting point for discussion, not a final offer.
| Type of premises | Floor 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 |
| Single-family house | ~100-150 m² | from approx. 9 000 to 16 000 zł |
Replacing an installation in an occupied flat (chasing grooves, plastering, painting) usually increases these amounts by 20-40%, while installation in an open shell state - reduces them, as there is no cost of chasing.
What exactly is included in the price
- Material - cables, back boxes, fittings (sockets, switches), switchgear in the distribution board (miniature circuit breakers, residual current devices, surge protection) and the distribution board itself;
- Labour - installation of points, laying and connecting cables, assembly and labelling of the distribution board, commissioning;
- Chasing and plastering - only during renovation in existing walls, usually charged per linear metre;
- Commissioning measurements - insulation resistance, effectiveness of shock protection, RCD operation - a report without which the handover is incomplete.
Standards that increase the price - but protect you
Part of the cost is not a "contractor's whim", but 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 a single circuit (including up to 10 sockets or 20 lighting outlets per circuit) - this ensures that in a proper installation there is no shortage of sockets where they are actually needed;
- PN-HD 60364-4-41 - requires residual current devices (RCDs) with a sensitivity up to 30 mA for socket circuits, and in new residential installations also for lighting;
- PN-HD 60364-7-701 - in the bathroom, it divides the space into zones 0/1/2 and imposes minimum distances of sockets from the bath or shower, as well as the requirement for equipotential bonding;
- PN-HD 60364-5-52 - links the cable cross-section with the protection and power of the receiver (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 one done "on a budget", but it is the difference between a home where the RCD actually protects you, and one where it only seems to do so.
How many points does a typical 3-room flat have (M3, ~50 m²)
For orientation - an illustrative comparison 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 flat comes to 30-40 points distributed over 10-14 circuits - and it is this number, not the floor area itself, that has the strongest impact on the price.
How to lower the cost without compromising safety
- Do not skimp on the number of circuits - adding another socket to an already existing circuit is cheap, but an overloaded circuit is the most common cause of tripped breakers;
- Choose mid-range accessories - the difference in price between the economy and premium series for 40 points can reach several hundred złotych without affecting safety;
- Plan in stages during renovation - the replacement can be divided into rooms instead of doing the entire property at once;
- Spread the payment into instalments - larger works can be broken down into 0% instalments instead of paying all at once.
An honest estimate before work: instead of guessing by the floor area, describe your apartment in the installation creator - you will see price ranges broken down into materials and labour before you even book a visit. If you prefer a visit, you will get the same quote via online booking.
