Account management tips
-
Set up auto-pay:

-
Check bills online:
- CLP: mypower.hk
- Towngas: mygas.hk
- WSD: wsd.gov.hk
- Monitor usage and bills anytime
-
Investigate abnormal usage:
- Sudden doubling of electricity bill → Check if AC or fridge is faulty
- Sudden high water bill → Check for pipe leaks (e.g., damp ceiling downstairs)
- Take photos and report to landlord for repairs
-
Settle accounts when moving out:
- Notify each company in advance during the final month
- Final bills usually arrive 2–4 weeks after moving out
- Keep deposit receipts for refunds
How to split and pay utilities when sharing a flat?
Recommended splitting methods
-
Simple equal split (3 people sharing)
- Each pays: total cost ÷ 3
- Pros: Simple and easy, avoids complex calculations
- Cons: High users benefit unfairly
-
Usage-based split
- Install individual submeters in each room
- Split based on actual usage
- Pros: Fair, encourages energy saving
- Cons: Higher cost, requires equipment
-
Fixed + variable split (recommended)
- Basic fees (meter charges): split equally
- Usage fees (kWh, cubic meters): split equally
- Result: Nearly fair, simple to implement
Payment process suggestions
- One person handles payments, others transfer via WeChat/PayPal monthly
- Track monthly costs, share bill screenshots in the group chat
- Settle at the start of each month to avoid arrears
