Electrical Renovation Cost: Price Analysis per Square Metre, Material Level and Scope

The first real shock in many renovations arrives when the owner asks for an electrical quotation and hears numbers that sound much higher than “just changing some sockets.” That happens because electrical renovation is not a single product. It is a package of strip-out work, new routing, boxes, cabling, panel upgrades, testing and often coordinated reinstatement.

If you want to compare quotations properly, you need to understand how the work is priced and what each number actually includes. Otherwise you end up comparing unlike with unlike and assuming one contractor is simply expensive, when in reality they may have included far more labour, better materials and a more complete scope.

1. The two main pricing methods

Two main pricing methods for electrical renovation

In the Greek market, electrical renovation is usually priced either per square metre or per point. Each method has its own logic, but each also creates different levels of accuracy and different traps when reading a quotation.

1️⃣ Price per square metre

This is the quick method for a first estimate. It is useful for early budgeting, but it can misrepresent homes with many loads, more complex planning or higher technical expectations.

2️⃣ Price per point

A “point” counts sockets, switches, lighting points and dedicated supplies. It is more accurate and fair because it reflects the actual density of the installation.

📌 What to request

Even if the first quotation is based on square metres, ask for a point breakdown and a clear scope of works. Only then can you compare two contractors on equal terms.

🧮 Why the two methods do not always lead to the same number

A flat with very few outlets and a simple board may look expensive per square metre but reasonable per point, while a smart, heavily serviced home may hide major cost behind an apparently average €/m² figure.

2. Where the money really goes

The final bill is not just “cable and sockets.” A large share of the cost sits in labour: marking, chasing, conduit installation, fixing boxes, pulling circuits, connecting the panel and carrying out final testing.

The rest is split across materials, the chosen equipment level and special protective devices. That is where the gap appears between economy, mid-range and premium solutions.

That is why two quotations with similar totals can have completely different internal logic. One may invest in labour quality, another may reduce material quality and a third may omit important protective devices altogether.

Cost breakdown between labour, materials and panel works

🔨 Labour and wall chasing

In older properties the heaviest cost is often the creation of new routes and the removal of the old network. The harder the wall build-up and the longer the runs, the more labour costs rise.

🧰 Installation materials

Conduits, boxes, cables, connectors, junction boxes and panel materials vary significantly in quality. Not all 2.5mm² cables or RCDs are equivalent.

⚡ Panel and protective devices

MCBs, RCDs, surge protection, contactors and proper circuit labelling can change the budget noticeably, but they are exactly the elements that define safety and maintainability.

3. Four factors that push the budget up

Not all homes cost the same to rewire even if they have the same floor area. The final amount depends heavily on the true difficulty of the job and on the owner’s choices about quality and future provisions.

Factors that increase the electrical renovation budget

1️⃣ Difficult or degraded wall construction

Hard concrete, stonework or awkward routes increase labour time and reinstatement complexity.

2️⃣ Many heavy loads

If the home will serve an electric cooker, multiple air-conditioning units, a heat pump or an EV charger, more dedicated circuits and a larger board are required.

3️⃣ Premium fittings and design ranges

Designer switches, sockets and branded mechanism ranges can raise the final quotation substantially compared with basic equipment lines.

4️⃣ Future-proofing provisions

Spare conduits, data points, smart home provisions and extra board capacity cost more today but prevent much more expensive interventions later.

5️⃣ The level of coordination and technical planning

The clearer the design, the load schedule and the coordination with other trades, the fewer surprises and repeat visits end up being charged at the end.

4. The hidden costs people often forget

The most common budgeting mistake is to count only the electrician’s direct work. In reality there are associated costs that, if not listed clearly in the quotation, appear later as unpleasant surprises.

Hidden costs and owner budget checklist

🧱 Making good and repairs

Who closes the chases? Are plaster, local repairs and patching included, or priced separately? This should be stated clearly.

📄 Testing and final documentation

Measurements, certification, final checks and installation declaration updates all take time and carry value. Do not assume they are free just because they are not visible hardware.

🚚 Surprises inside the old network

Once walls are opened you may discover missing earthing, rotten junction boxes or improvised joints. A sensible contingency allowance is always necessary.

🗂️ The detail level that saves your budget

Ask for the number of circuits, board scope, material level and exclusions to be stated clearly. Anything left vague usually returns later as extra cost.

💡 The cheapest quotation is often not the most economical one. It is simply the vaguest.
