Planning your electrical system is one of the most important – yet often overlooked – steps when building or renovating a home. Poorly placed light switches, too few outlets, or missing network connections can become daily annoyances or lead to expensive corrections later. According to a survey by Germany’s Homeowners Protection Association, over two-thirds of homeowners regret decisions made in their electrical planning. And with technology advancing quickly – think smart homes, electric car charging, or automated blinds – today’s planning needs to anticipate tomorrow’s needs, reports G.Business.
This clear, structured checklist helps you plan every essential detail: from lighting and switches to outlets, outdoor access, and smart features. Whether you're building, remodeling, or just upgrading your home, this guide walks you through every decision. Plus, you’ll get practical expert tips most electricians won’t tell you unless you ask.
LIGHTING & SWITCHES – WHY PLACEMENT MATTERS
Lighting isn’t just about brightness – it affects mood, safety, and usability. Yet in many homes, switches and fixtures are placed based on gut feeling rather than need. A structured approach saves time and ensures that your lighting matches your real-life habits – especially in hallways, bedrooms, and staircases. Also, consider dimmers, dual switches, and motion sensors for smarter control.
Lighting & Switch Checklist
- Ceiling lights should be centered in each room
- For rooms over 20 m², consider two fixtures or combine with wall lights
- Two switches per light: at the entrance and near the main activity zone (e.g. bed, desk)
- Dimmer switches in living rooms, dining areas, and bedrooms
- Dual switches (two-way) in hallways and on stairs
- Motion sensors in guest bathrooms, closets, basement stairs
OUTLETS – NEVER UNDERESTIMATE HOW MANY YOU NEED
Outlets power your daily life, yet most homes end up with too few. Following building code standards is not enough anymore. Laptops, TVs, phone chargers, kitchen appliances, and smart devices all need power. Always install more outlets than you think you'll need – especially in the kitchen, living room, and home office.
Outlet Guide (Minimum + Recommended)
| Room | Minimum (Standard) | Recommended Count |
|---|---|---|
| Living Room | 6 | 10–12 (with TV/audio) |
| Kitchen | 10 | 14+ (appliances!) |
| Bedroom | 4 | 6–8 |
| Home Office | 6 | 8–10 (computer, printer) |
| Hallway/Entryway | 2 | 4+ (e.g., for vacuum) |
Tip: Don’t forget outlets behind furniture, under windowsills, or embedded in countertops.
OUTDOOR ELECTRICITY – ESSENTIAL BUT OFTEN MISSED
Outdoor areas are frequently underplanned, even though we use them year-round. Whether it’s for lighting, power tools, music at garden parties, or Christmas decorations – your garden needs electricity. Weatherproof outlets and secure switches are a must, and if you're planning awnings or outdoor lighting, those need connections too.
Outdoor Checklist
- 3 double weatherproof outlets: terrace, water tap, garden shed
- 1 dedicated outlet at the street front for Christmas lights
- All outdoor sockets should be switchable from inside (for safety)
- Plan wiring for awnings, electric blinds, and weather sensors
- Consider motion-activated lights for entrance or garden path
SMART COMFORT & FUTURE-PROOFING
Modern homes need more than outlets and switches. Smart home integration, security, energy management, and flexibility for the future are now standard. You don’t need to automate everything today – but you should plan for it. Installing empty conduit tubes and additional network ports can save thousands down the line.
Smart Planning Essentials
| Feature | Recommendation |
|---|---|
| Network ports | In office, living room, and possibly bedrooms |
| Phone jacks | Optional: hallway, office, or kitchen |
| Smart home conduit (empty) | Always install, even if unused at first |
| Door intercom | Video modules at front door + 2nd station upstairs |
| Smoke detectors | Use wired power, not just battery |
| All-off switch | Near the bed for central shutdown |
| Panic button | Optional in bedroom for emergency use |
| EV charging (Wallbox) | Install high-voltage outlet in garage/carport |
WHAT THE NUMBERS SAY
| Insight | Source | Figure |
|---|---|---|
| Homeowners with too few outlets | Homeowners Protection Assoc. | 68 % |
| Required rework after build (wiring etc.) | Statista / Consumer Advice | 32 % |
| Average cost of post-installation fixes | Bauinfo24 | €3,000–4,000 |
| Dissatisfaction with light switch placement | Elektro+ | 43 % |
| Planned for future smart tech (e.g., tubes) | Bitkom | 27 % |
10 REAL-LIFE PRO TIPS
- Plan for future devices you don’t own yet (EV, solar, AC)
- Add 20% more outlets than the standard recommends
- Install hidden outlets behind beds, sofas, and curtains
- Use two-way switches in hallways and bedrooms
- Install motion sensors in small rooms and stairways
- Include USB outlets near beds and desks
- Add an “all-off” switch near the bed for night use
- Lay empty conduit tubes even if you don’t use them yet
- Make sure all outdoor sockets can be turned off from inside
- Walk through the floorplan with a vacuum in mind – where would you plug it in?
Conclusion: Practical, Safe, and Ready for the Future
Electrical planning isn’t just about wiring – it’s about how you live. Every outlet, switch, and cable influences your daily comfort and safety. Done right, it saves time, money, and stress – and gives you room to grow.
Your next steps:
- Copy your floorplan and walk through each room in your mind
- Use this checklist to mark all key spots and devices
- Talk with your electrician before walls are closed
- Always plan for tomorrow – not just today
Because your house will stay, but your needs will change. And electricity is what makes it all work.
