EICR for communal areas in London blocks of flats

A report on the common parts examines the installation that serves those parts. It does not examine a flat's consumer unit and final circuits unless the extent says so. A flat EICR does not examine the riser, the stair lighting or the plant the freeholder controls unless that work was included.

A satisfactory communal report does not substitute for a flat EICR where the private installation requires its own certificate. Conversely, a flat EICR does not automatically cover risers, external lighting or plant controlled by the freeholder.

This page explains planning and reading communal inspections in London blocks. It is guidance for landlords, leaseholders and managing agents — not a determination of legal responsibility for a specific building without reviewing title, lease and maintenance agreements.

Communal inspections commonly cover corridor and stair lighting, landlord sockets in common parts, fire-alarm and emergency lighting supplies where part of the landlord installation, external car-park lighting, entry systems, lifts' landlord supplies, ventilation plant, and distribution equipment in riser cupboards serving multiple demises.

Installations wholly within a leaseholder's flat — consumer unit, final circuits and accessories — fall within the flat installation unless the report explicitly states a wider scope. Meter cupboards may contain both landlord and tenant equipment; demarcation must be clear on the report.

The EICR front sheet, extent and limitations sections define what was inspected. Always read those before assuming a certificate covers the whole block.

Freeholders, resident management companies and appointed managing agents typically arrange communal electrical maintenance and periodic inspection for landlord-controlled installations. Individual flat landlords remain responsible for EICRs on installations within their let flats under private rented sector rules where applicable.

Lease terms vary on cost recovery through service charges and on access to risers or plant rooms. Disputes about who should remediate a finding in a riser cupboard often turn on lease wording and whether the defect affects landlord or tenant equipment.

London EICR Certificates can inspect domestic flat installations and commercial or communal scopes where agreed. Block-wide coordination may require managing-agent involvement for access and scope confirmation.

The private-rented duty in England applies to the electrical installation in the rented dwelling. A report on the block's common parts does not, by itself, meet that duty for a let flat. A flat report does not, by itself, describe the landlord's riser or stair lighting.

Where a defect in a shared riser affects a flat, the lease and the maintenance arrangement decide who instructs the work. This page does not read a particular lease.

• Damaged or non-compliant light fittings in stairwells and car parks.
• Missing RCD protection on landlord socket circuits in common parts.
• Exposed or deteriorated wiring in plant rooms and riser cupboards.
• Inadequate earthing or bonding at landlord distribution boards.
• Emergency lighting supplies not maintained or incorrectly tested — may involve separate standards.
• Consumer unit enclosure damage or incomplete blanking in landlord cupboards.

The codes mean the same thing as on a domestic report, and they are still the inspector's judgement of that installation. C1 is danger present. C2 is potentially dangerous. C3 is improvement recommended. FI means further investigation is advised. Under the current A4:2026 format, an FI observation is advisory and does not by itself make the overall assessment unsatisfactory.

A stairwell used by many people is context for the observation. It is not a rule that every communal defect is C2.

Communal inspections require keys to riser cupboards, plant rooms, roof areas and external lighting controls. Managing agents should notify residents about access needs without claiming statutory entry rights beyond their actual authority.

Live blocks may need phased testing to minimise disruption to lifts, fire systems or pumps. Scope should be agreed in advance so the inspection is not limited unexpectedly, producing FI items that could have been resolved with planning.

Flat landlords booking flat-only EICRs should still disclose known communal defects reported elsewhere that might affect the flat installation.

Mixed-use blocks with retail or office frontages may have separate landlord installations for commercial areas. Dutyholder context can differ from purely residential common parts.

Commercial periodic inspection intervals and reporting formats may apply to non-domestic areas. A residential communal report should not be assumed to cover shop units unless explicitly included.

Our commercial EICR guidance covers wider non-domestic inspection planning; this page focuses on residential block common parts.

“One block EICR covers every flat” is usually incorrect unless each flat installation was within agreed scope.

“Communal lighting is low risk, so the code is always C3” is not a rule. A damaged fitting on a stair is judged from that fitting, not from the fact that it is communal.

“The flat landlord never needs to care about risers” ignores shared equipment that can affect flat safety and compliance evidence.

Managing agents: confirm scope, obtain the full communal EICR, log C1/C2/FI items, and instruct competent remedial contractors with riser access arranged.

Flat landlords: retain flat-specific EICRs for let properties, request communal report summaries from agents where relevant, and escalate shared defects formally.

Check pricing for commercial or communal scopes through enquiry rather than assuming domestic flat calculator rates apply. Contact our team if scope boundaries are unclear before booking.

For shared supplies, landlord boards or plant, request a commercial or communal inspection quotation with the installations and access arrangements clearly identified.

The codes on a communal report are the inspector's judgement of that installation. This page does not interpret a lease or a title document.

Responsibility and scope vary by building. Confirm dutyholder obligations with managing agents, solicitors or advisers for your block before relying on generic guidance.

In a reviewed North London job, the flat and communal installation had separate EICRs. Both recorded satisfactory assessments, each within its own scope. The example shows why the installation named in the instruction matters.
