POWER LOSS & SUPPLY FAULT GUIDE

Electricity Meter Has No Display

A blank electricity-meter display may be normal sleep mode, a local outage, failed meter, depleted internal display supply, prepayment issue or loss of incoming supply.

!

Stop if there is heat, burning, arcing, exposed parts or damaged supply equipment

Do not remove consumer-unit covers, open electricity meters, disturb sealed cut-outs or touch exposed conductors. Leave affected equipment off and contact a registered electrician, supplier or network operator as appropriate.

MOST LIKELY CAUSES

Start with these

Display asleep Some smart and digital meters blank until a button is pressed.
Local power outage The meter may not be receiving incoming supply.
Meter fault The display or internal electronics may have failed.
Prepayment or supplier issue Credit, emergency credit or remote status may affect supply.
◫ Symptom variations Match the exact pattern before testing. ⌄
  • Meter screen completely blank
  • Display wakes when a button is pressed
  • House has no power
  • Meter blank but house still has power
  • Prepayment meter will not reconnect
✓ Quick checks Safe checks using front-panel controls and visible information only. ⌄
  1. Check whether the whole property or only certain rooms are affected.
  2. Look for a wider local outage.
  3. Inspect the consumer unit for a tripped breaker, RCBO, RCD or main device.
  4. Check the electricity meter display and prepayment status where applicable.
  5. Attempt one controlled reset only if there are no danger signs.
If power returns: reconnect or restore loads gradually and monitor the supply.
If the fault remains: leave affected circuits off and arrange the correct professional response.
1 Fix 1 — Wake the display Follow this check without opening live or sealed electrical equipment. ⌄

Process

Press an accessible display button once without removing covers.

Success looks like: The screen wakes and shows normal information.
Failure means: If it remains blank, continue with supply checks.
2 Fix 2 — Check for a wider outage Follow this check without opening live or sealed electrical equipment. ⌄

Process

Look at neighbouring properties and network status.

Success looks like: A local network outage is confirmed.
Failure means: If only your meter is affected, contact the supplier.
3 Fix 3 — Contact the correct organisation Follow this check without opening live or sealed electrical equipment. ⌄

Process

Report meter faults to the electricity supplier and external supply loss to the network operator.

Success looks like: The fault reaches the responsible party.
Failure means: Do not open sealed meter or cut-out equipment.
⌁ Common causes explained Why the power or supply may fail. ⌄

A blank electricity-meter display may be normal sleep mode, a local outage, failed meter, depleted internal display supply, prepayment issue or loss of incoming supply.

Power loss can originate inside the property, at the meter, or on the electricity network. Identifying which protective device operated and how much of the property is affected is the quickest way to narrow it down.

⌘ Advanced diagnostics Technician-level testing for a competent electrician. ⌄
  • Confirm incoming supply at the agreed boundary.
  • Check consumer-unit supply independently of display state.
  • Inspect for visible heat damage without disturbing seals.
  • Coordinate meter replacement with the supplier.
  • Escalate cut-out or network faults to the distribution network operator.
▣ Parts that may need replacing Components commonly linked to this fault. ⌄
  • Electricity meter by supplier
  • Meter isolator
  • Prepayment interface
  • Network cut-out or fuse by operator
  • Display unit where separate
! When to call an electrician or supply provider Conditions that should end DIY troubleshooting. ⌄
  • The fault remains after one controlled reset.
  • There is burning, heat, buzzing, crackling or visible damage.
  • The main switch, RCD or breaker will not stay on.
  • The meter or sealed supply equipment appears damaged.
  • Lights become unusually bright or voltage appears unstable.
  • Only your property is affected and no internal protective device has operated.
? Frequently asked questions Common questions about supply faults. ⌄

Who should I call for a complete power outage?

Check whether neighbours are affected. A wider outage belongs to the electricity network operator; a fault limited to your installation may need an electrician.

Can a faulty appliance cut power to several rooms?

Yes. One appliance can trip an RCD that protects several circuits.

Should I repeatedly reset the main switch or RCD?

No. One controlled reset is enough to establish whether the fault remains.
