How Long Does
an EICR Take

How long UK EICR inspections actually take in different properties

EICR duration varies significantly based on property size, age and complexity. Most UK domestic EICRs take 2-4 hours but plan for half a day to be safe. The electrician needs uninterrupted access to consumer unit, all sockets and accessories. Power will be temporarily off during testing.

Typical UK domestic EICR timings:

• 1-bedroom flat or studio. 1.5-2 hours. Limited circuits and accessories.
• 2-bedroom flat or small terraced house. 2-2.5 hours.
• 3-bedroom semi or detached house. 2-4 hours typical.
• 4-bedroom house. 3-5 hours.
• 5+ bedroom property. 4-6 hours.
• Older properties (pre-1980). Add 30-60 minutes for extra investigation.

Commercial property EICR timings:

• Small office or shop. 3-5 hours.
• Restaurant or pub. Half day (4-6 hours).
• Larger retail premises. Half day to full day.
• Industrial unit. Half day to full day depending on machinery and complexity.
• Multi-storey building. Multiple days possible.
• Schools and care homes. Multiple days for full inspection.

What the electrician actually does during EICR:

• Visual inspection (30-60 minutes for typical home). Check consumer unit, sockets, switches, light fittings, visible cabling.
• Insulation resistance testing (30-60 minutes). Tests insulation between live and earth on each circuit.
• Continuity testing (30-60 minutes). Checks earth continuity and ring main continuity.
• Polarity testing (15-30 minutes). Checks live and neutral are correctly wired.
• RCD testing (15-30 minutes). Tests residual current device trip times.
• Accessibility checks throughout. Various sockets and switches accessed.
• Documentation (30-60 minutes during or after). Record findings on EICR document.

Factors that increase EICR time:

• More circuits. Each circuit needs individual testing.
• Older property. Original wiring may need extra investigation.
• Inaccessible consumer unit. Behind furniture or in awkward location.
• Unusual installations. Non-standard wiring, additions, modifications.
• Multiple distribution boards. Larger properties or businesses.
• Heating systems with controls. Underfloor heating, smart heating zones.
• Electric vehicle chargers. Need separate testing.
• Solar PV systems. Extra inverter and battery testing.
• Outdoor installations. Garden lights, outbuildings, hot tubs.

What the property owner needs to do:

• Provide access. Be present or arrange access for the entire estimated duration.
• Clear consumer unit access. Move stored items if access blocked.
• Clear access to outlets. Move large furniture if blocking sockets.
• Remove pets and children. Power-off periods can be hazardous with children playing.
• Inform tenants if rental. Let them know about power interruptions.
• Plan for power off. Save important computer work, defrost food, etc.

Power interruption during EICR:

• Each circuit needs to be temporarily powered off for testing.
• Total power-off time: 30-60 minutes spread across the visit.
• Electricians try to minimise disruption.
• Sometimes whole-property power off briefly (15-30 minutes).
• Plan for: saving work, fridges and freezers staying closed, no critical equipment running.
• Some equipment (medical devices, fish tanks) may need backup arrangements.

Time savings for the inspection:

• Provide previous EICR. Helps electrician understand history.
• Provide circuit list. If consumer unit doesn't have clear labelling.
• Clear access. Reduces time spent moving things.
• Be available for questions. Quick clarification beats waiting.
• Schedule for full daylight. Easier for outdoor and natural-light inspection.

What to expect at the end of EICR:

• Electrician completes the EICR document.
• May provide on-site or send within 1-7 days.
• If issues identified, discuss next steps and timeline for remedial work.
• Get clear quote for any remedial work needed.
• Schedule retest after remedials if Unsatisfactory result.

EICR vs other inspection times:

• Domestic EPC. 30-60 minutes typically. Much faster than EICR.
• Gas Safety Certificate (CP12). 30-60 minutes per gas appliance.
• Building survey. 2-4 hours plus written report.
• Smoke alarm test. 15-30 minutes.
• EICR is one of the more time-intensive property inspections.

Can EICR be done partially or in stages:

• Generally no - EICR must be completed in one visit for accurate results.
• Some commercial environments may have phased inspections (e.g. multi-floor offices).
• Domestic EICR cannot easily be split.
• Plan for full duration in one visit.
• If you must reschedule, count it as a fresh start.

UK EICR timing best practice:

• Book morning slot if possible (allows extra time if needed).
• Choose weekday during business hours for fastest scheduling.
• Allow flexibility - some inspections finish early, some take longer.
• Plan to be home or have someone available for the entire period.
• Have any previous certificates ready for reference.
