Electrical work is one of the costliest and most consequential parts of any renovation. Homeowners usually imagine bright lights and convenient outlets, while contractors see miles of cable and a hefty electrical panel. That gap in perspective often explains budget surprises. To clarify where it’s safe to save—and where cutting corners is a bad idea—an experienced specialist offered five practical pointers.

Your electrical budget should match the scale of the renovation

On average, the electrical scope takes about 10–15% of the total project cost. If you’re planning a one‑million‑ruble renovation, it’s clear that a hundred breakers and kilometers of premium cable won’t fit. Set in advance how much you’re ready to invest in the engineering side. That keeps expectations realistic and helps balance spending across electrical work, finishes, and plumbing.

How many outlets you need is about comfort and common sense

Outlets are among the most debated elements of a project. The more points you add, the higher the final bill. But over‑saving can lead to extension cords everywhere and an overloaded network. Experts suggest a minimum of two to four outlets per room. If a professional is designing the project, they’ll help fine‑tune placement.

If you’re planning on your own, mark the outlets on a floor plan and check whether they truly cover daily needs. If the estimate balloons, you can pare back the count. The guiding principle is simple: don’t end up relying on splitters and cable tangles.

Appliances that run unattended should have their own breakers

The refrigerator, router, security system, and sensors—anything that stays on when you’re away—is better connected through dedicated breakers.

That brings two advantages:

• it prevents overloading a general line;
• it lets you switch off a specific outlet or circuit without affecting the rest of the home.

If half your outlets share one breaker, turning on a kettle and a vacuum cleaner at the same time can be enough to trip protection.

You can save on combined protection—if you do it smart

A differential breaker pairs a circuit breaker with an RCD in one device. It’s convenient and keeps the panel tidy, but it costs more. The alternative is a standard breaker plus a separate RCD. Functionally, the setup is nearly equivalent and noticeably cheaper—a pragmatic choice when the budget is tight.

Be sensible when saving on hardware

There’s a straightforward rule: equipment from proven manufacturers tends to last longer and work more reliably. Even with a limited budget, it’s wiser to consider the more affordable series of well‑known brands like Schneider and Legrand. No‑name bargains can fail much sooner and, at times, pose safety risks. Saving on quality can easily turn into repeat work—or an emergency.

Sound electrical planning blends safety, convenience, and measured spending. A realistic budget, a thoughtful number of outlets, dedicated breakers for critical devices, and trusted components help you renovate without overpaying—or facing unpleasant surprises later.
