Planning electrical points before house construction begins is one of the most critical yet commonly overlooked steps. Once walls are plastered and painted, adding new electrical points means breaking walls, re-routing wires, and repainting entire sections. This guide covers room-by-room electrical planning, common mistakes, brand recommendations, and cost estimates for homes in Greater Noida and Noida.

Electrical Points House Construction — Why Plan Electrical Points Early?
Electrical planning must happen at the architectural design stage, before construction begins. Here is why early planning matters:
- Adding points after construction costs 3-5x more due to wall-chasing and replastering
- Furniture layout determines switch and socket placement
- Modern homes need far more points than older designs accommodate
- Safety requirements (MCB sizing, earthing, wire gauge) must be planned for total load
- Concealed wiring in conduits can only be done during construction phase
Room-by-Room Electrical Points Guide
Master Bedroom (8-12 Points)
- 2 switch boards near bed (both sides) with 5A sockets for phone charging and lamps
- 1 switch board near dressing table with 15A socket for hair dryer
- 1 AC point (15A/20A) at 7 feet height
- 1 TV point with power and cable/ethernet socket
- 2 light switches (main light + accent/cove light)
- 1 fan regulator point
- 1 5A socket near wardrobe for iron/steamer
Kitchen (12-15 Points)
- 1 point for refrigerator (15A, always on)
- 1 point for microwave (15A)
- 1 point for chimney/exhaust
- 1 point for water purifier
- 1 point for dishwasher (if planned)
- 2-3 countertop sockets for mixer, toaster, kettle (15A)
- 1 point for washing machine (near utility/kitchen)
- 1 point for geyser (if kitchen has hot water)
- 2 light points (main ceiling + under-cabinet LED)
- 1 exhaust fan point
Living Room (10-14 Points)
- 1 TV unit point (power + HDMI conduit + ethernet)
- 1 AC point (15A/20A)
- 2-3 floor-level 5A sockets for lamps and vacuum cleaner
- 1 point near sofa for phone charging
- 2-3 light circuits (main chandelier, cove lighting, accent spots)
- 1 fan point
- 1 point for WiFi router
- 1 point for set-top box/gaming console
Bathroom (4-6 Points)
- 1 geyser point (15A, outside splash zone)
- 1 exhaust fan point
- 1-2 light points (main + mirror light)
- 1 shaver/hair dryer socket (with safety switch)
- All bathroom points must be at safe distance from water sources as per IS standards
Common Electrical Planning Mistakes
- Too few kitchen sockets — Modern kitchens need 12-15 points minimum. Most old designs have only 4-6.
- No bedside sockets — Forgetting charging points near both sides of the bed is the most common complaint.
- Wrong AC point height — AC points should be at 7 feet, not near the ceiling. This avoids exposed wiring from the socket to the indoor unit.
- No separate circuits — Heavy appliances (AC, geyser, oven) need separate MCBs and dedicated wiring. Sharing circuits causes tripping.
- Ignoring future needs — Plan for EV charger point in parking, smart home wiring, and CCTV cable conduits even if not installing immediately.
Modular Switch Brands for Indian Homes

Wiring Plan with Your Architect
At Aarna Constructions, electrical planning is integrated into our architectural design process. Our architects create a detailed electrical layout showing every switch, socket, light point, and data point on the floor plan. This drawing is shared with you for approval before construction begins, and handed to the electrician as a working document. Changes after wall plastering are avoided completely.
Electrical Cost Estimation
For a typical G+1 house (2000 sq ft built area) in Greater Noida:
- Wiring (Havells/Polycab FR cables): Rs 45,000-65,000
- Modular switches (GM/Havells): Rs 25,000-40,000
- DB box + MCBs + RCCB: Rs 8,000-15,000
- Electrician labor: Rs 20,000-30,000
- Total: Rs 98,000-1,50,000

Electrical points — room-by-room guide
Electrical layout is a one-shot decision during construction; retrofitting costs 4-6x more than getting it right initially. Below is the room-by-room electrical point count reference our designers use for Greater Noida builds.
Room-by-room electrical points count
Practical electrical point count per room for modern Greater Noida flats and villas.
| Room | Modern count | Notes |
|---|---|---|
| Master bedroom | 12-16 | AC + bed lamps + TV + study + fan + general |
| Other bedrooms | 8-12 | AC + lamps + fan + general |
| Living + dining | 12-18 | TV + multiple sockets + dimmers + AC |
| Kitchen | 10-14 | Chimney + hob + fridge + microwave + mixer + RO + lights |
| Each bathroom | 4-6 | Geyser + exhaust + mirror + shaver point |
| Foyer | 2-3 | Doorbell + 1-2 sockets + ceiling light |
| Utility / balcony | 3-5 | Washing machine + iron + 1 spare socket |
| Pooja room | 1-2 | Lamp + diya socket |
| Study (if separate) | 5-7 | Computer + lamp + printer + AC |
| Stairs (villa) | 2-3 | Way-finding + step lighting |
Six electrical decisions most owners regret skipping
AC point in every bedroom
Even if you use AC in only master now, wire all bedrooms. Adds Rs 12-18k; saves Rs 40-60k retrofit per room later.
5A vs 15A planning
Modern homes need 15A for AC, fridge, microwave, geyser. Old 5A wiring trips. Plan circuit load carefully.
Modular switches throughout
Anchor / Legrand / Schneider modular vs old piano switches. Rs 8-15k extra for 2BHK; transforms aesthetic.
Concealed wiring (always)
Never accept exposed wiring in modern build. Concealed PVC conduit + pull wire for future upgrades.
Earthing per floor (RCC)
Separate earth pit per floor in villa builds. Saves grounding issues + appliance damage from voltage fluctuations.
Generator + inverter pre-wiring
Even if you don’t install genset now, pre-wire the changeover switch + main inverter line. Rs 8-12k now; saves Rs 40-80k retrofit.
Frequently asked
How many electrical points does a modern 3BHK need?
38-48 points across all rooms (master 14, other bedrooms 10+8, kitchen 12, living/dining 16, bathrooms 5+5, foyer 3, utility 4). Modern smart homes can need 60+.
What is the cost difference between basic and modern electrical?
Basic (just 5A sockets + tube lights): Rs 35-55k for a 2BHK. Modern (15A points + modular switches + concealed wiring + AC points): Rs 90-1.4L for a 2BHK. Worth it for liveability + resale.
Can I add electrical points after construction?
Yes but expensive: Rs 700-1,200 per point including chasing wall, conduit, pulling wire, fitting modular switch, repainting. For a 10-point retrofit, expect Rs 8-12k + disruption.
Modular vs standard switches — what is the difference?
Modular switches (Anchor Roma, Legrand Myrius, Schneider AvatarOn) are flat-faced, slim, available in white/black/metal finishes. Old piano switches stick out, look dated. Cost difference: Rs 80-200 per switch; transforms wall aesthetic.

Frequently Asked Questions
A modern 3BHK needs 60-80 electrical points total including switches, sockets, light points, AC points, and data points.
Use 4 sq mm copper wire for AC (1.5 ton) and geyser circuits. Regular lighting circuits use 1.5 sq mm wire. Power sockets use 2.5 sq mm wire.
Yes, even if not installing smart switches now, lay extra conduits and neutral wires at all switch points for easy retrofitting later.
Sum all appliance wattages, add 20% safety margin. A typical 3BHK needs 8-10 kW total load capacity.
