Replacing common-area light fittings with LED

Replacing common-area light fittings with LED devices cuts energy use and maintenance. If it means replacing existing lamps and fixtures while keeping the function, the work is maintenance and can be arranged by the manager or resolved by simple majority; if it involves rewiring the system or a substantial change, it may amount to an improvement under Article 1120 of the Italian Civil Code, with the eased majorities provided for energy-saving works. The cost is shared according to the use of the parts served.

Why switch to LED in common parts

Lighting of stairs, halls, courtyards and garages is often on for long periods and weighs noticeably on common electricity use. LED devices, combined with presence sensors and timers, consume less and last longer than old lamps, cutting both the bill and the frequency of replacements. The economic benefit adds to improved safety, because well-lit areas reduce the risk of falls and unwanted behaviour.

Maintenance or improvement: the distinction that matters

The legal classification of the work determines the required majority. If you simply replace faulty light sources or fixtures with LED equivalents, without changing the system, you stay within maintenance. If instead you rewire the line, add new light points or introduce automatic control systems, the work may take on the character of an improvement under Article 1120 of the Italian Civil Code.

For improvements aimed at energy saving and efficiency, the law provides eased majorities compared with ordinary improvements, to encourage this type of work. It is therefore important to classify the project correctly before bringing it to the meeting.

Who decides and by what majority

Simply replacing faulty lamps falls within the manager's duties under Article 1130 of the Italian Civil Code. A programme to replace all common lighting, with an appreciable cost, must be resolved by the meeting under Article 1135, with the majorities of Article 1136. When the work qualifies as an improvement for energy saving, the eased majorities provided by the rules for this purpose apply.

Cost sharing

The cost is shared according to the common part served by the lighting.

• Stairwell lighting: the criterion of Article 1124, half by thousandths and half by floor height.
• Lighting of the hall and spaces serving everyone: general thousandths, Article 1123, first paragraph.
• Lighting of parts serving only some units, such as a staircase or reserved courtyard: only the owners concerned, Article 1123, third paragraph.
• Electricity consumption: follows the same criterion as the element lit.

Electrical system safety

Any work on the common electrical system must comply with technical safety standards and, where required, be carried out by a licensed company issuing the declaration of conformity. This is not a formality: a compliant system protects the condominium in terms of liability and insurance cover. The manager must keep the technical documentation together with the building's other records.

Assessing the return on investment

Before resolving, it is worth estimating the expected saving on the bill and comparing it with the cost of the work, so as to show the meeting how long the investment takes to pay back. A detailed estimate and a consumption projection make the decision better informed and reduce objections from more cautious owners.

Planning the work and monitoring consumption

Scheduling the replacement, comparing estimates and checking the saving on common consumption is easier with suitable tools. Management software such as AmministraPro lets you attach estimates, record the resolution, share the cost according to the correct table and keep an eye on how the common bills evolve.
