Managing a block of flats in London is never just about repairs and service charges.
You are dealing with leaseholders, landlords, tenants, access issues, contractor coordination, compliance deadlines, safety risk, and the constant challenge of working out who is responsible for what. Electrical safety is one of the areas where confusion happens fast, especially when a building has a mix of private flats, communal installations, and landlord-owned electrical supplies.
That is why so many managing agents, RTM companies, freeholders, and block management companies ask the same thing:
Who is responsible for the EICR in a block of flats?
Is it the landlord of each flat?
Is it the freeholder?
Is it the management company?
Does the communal area need its own EICR?
What about landlord supplies, meter cupboards, hallway lighting, plant rooms, and shared systems?
The real answer is not one-size-fits-all.
In most London residential blocks, EICR responsibility depends on which part of the installation is being controlled, maintained, or supplied. That means one building can have multiple responsibilities across different electrical systems. The wiring inside a rented flat may fall under one party, while communal lighting, shared distribution boards, and landlord supplies fall under another.
This guide explains it properly.
We will break down:
- what an EICR covers in a block of flats
- who is usually responsible for private flats
- who is usually responsible for communal areas
- who normally handles landlord electrical supplies
- when a block needs separate inspections
- common mistakes block managers make
- real-world examples from London properties
- how to arrange the right inspection without wasting time or money

What Is an EICR and Why Does It Matter in a Block of Flats?
An Electrical Installation Condition Report, or EICR, is an inspection of an electrical installation to assess whether it is safe for continued use. It checks the condition of fixed wiring, boards, circuits, earthing, protective devices, and other parts of the installation. It also identifies defects, deterioration, damage, poor workmanship, or non-compliance with current safety standards.
In a normal house or flat, that is pretty straightforward.
In a London block, it is not.
A residential building can include:
- individual flat consumer units
- landlord intake equipment
- communal distribution boards
- shared hallway lighting
- stairwell lighting
- external lighting
- emergency lighting supplies
- door entry systems
- gate supplies
- meter cupboards
- riser cupboards
- plant room circuits
- ventilation and booster systems
- concierge or cleaner power supplies
That means the electrical installation is often split into multiple parts with different users, different responsibilities, and different access arrangements.
This is exactly why block management companies need a proper understanding of EICR scope. Booking “an EICR for the building” without understanding what is actually being inspected is how problems start.

Who Is Responsible for EICR in a Block of Flats in London?
This is the core question, and here is the clearest answer:
Responsibility for an EICR in a block of flats usually follows ownership, control, maintenance obligation, or supply of that part of the installation.
So the building may not have one single responsible person for everything.
Instead, responsibility is normally split across:
- private flat installations
- communal electrical installations
- landlord electrical supplies
- mixed-use or commercial areas where applicable
That is why a block management company needs to think in sections, not assumptions.
Let’s break those down properly.
1. Private Flats: Who Normally Arranges the EICR?
For the wiring and fixed electrical installation inside an individual flat, responsibility is usually linked to the person who owns or lets that flat.
If the flat is rented
The landlord is usually responsible for arranging the EICR covering that flat’s installation. This normally includes the consumer unit, socket circuits, lighting circuits, cooker circuit, and fixed wiring within the demised premises.
That is why we offer dedicated EICR Certificates for Landlords in London, designed for rented properties that need compliant electrical inspections and clear reporting.
If the flat is owner-occupied
The owner of the flat would usually be responsible for their own electrical inspection when required.
If the flat is vacant or under sale
Responsibility usually still sits with the legal owner or landlord of that unit, unless the lease or ownership structure states otherwise.
Key point
A block manager is not automatically responsible for the wiring inside private flats just because they manage the building overall.
That confusion causes a lot of wasted time.
2. Communal Areas: Do They Need a Separate EICR?
Yes, in many cases they do.
Communal areas in a block often have their own electrical installation or landlord-fed circuits that serve shared spaces. These areas are not part of one private dwelling, so they should not be assumed to be covered by an individual flat EICR.
Communal electrical installations often include:
- corridor lighting
- stairwell lighting
- lobby lighting
- bin store lighting
- bike store lighting
- external lighting
- communal socket outlets
- cleaner sockets
- riser cupboard lighting
- meter room lighting
- shared fire escape route lighting
- supplies feeding emergency lighting systems
- access control equipment
If those circuits exist, they need to be assessed as part of the communal or landlord-controlled installation.
Who is usually responsible for communal areas?
This is normally the party responsible for the common parts of the building, such as:
- the freeholder
- the Residents’ Management Company
- the Right to Manage company
- the block management company acting on behalf of the legal owner or management entity
So yes, communal areas often need their own EICR, separate from the flats.
3. Landlord Supplies: The Part Most People Miss
This is the section where a lot of buildings get caught out.
Landlord supplies are electrical circuits or boards that are not inside a private flat but are still part of the building’s wider electrical setup. They are often hidden in intake cupboards, service cupboards, basements, plant rooms, or risers.
Examples include:
- landlord distribution boards
- meter cupboard supplies
- hallway and stairwell circuits
- external lighting circuits
- shared ventilation or extract supplies
- booster pump power supplies
- plant room circuits
- gate motors
- door entry systems
- concierge or caretaker supply circuits
- shared service equipment
These are easy to overlook because they are not always obvious during day-to-day management.
A building can have flat EICRs in place and still have no proper inspection at all for landlord supplies.
That is a serious weak point.
If your building includes more complex shared or service-based installations, our Commercial EICR Certificates in London page is also relevant, especially for mixed-use or multi-service buildings.
Responsibility Matrix: Flats vs Communal Areas vs Landlord Supplies
Here is the cleanest way to look at it:
| Area of Installation |
Usually Responsible |
Notes |
| Wiring inside a rented flat |
The landlord of that flat |
Usually covered by a domestic landlord EICR |
| Wiring inside an owner-occupied flat |
The flat owner |
Normally private responsibility |
| Communal hallway lighting |
Freeholder / management company / RTM |
Usually not covered by flat EICRs |
| Stairwell and lobby circuits |
Freeholder / management structure |
Needs communal inspection where applicable |
| Landlord distribution board |
Freeholder / management structure |
Often overlooked |
| Meter cupboard landlord-fed circuits |
Freeholder / management structure |
Should be identified clearly |
| Plant room and shared service circuits |
Freeholder / management structure |
May require more specialist scoping |
| Ground-floor commercial unit |
Often separate occupier or landlord |
Depends on lease and supply layout |
This is why there is often more than one EICR requirement in the same building.
Can One EICR Cover the Whole Building?
Sometimes, but often no.
That depends on how the installation is structured.
A single EICR might work if:
- the building has one clearly defined landlord-controlled installation
- there are no private flat installations included
- the scope is limited to communal and shared electrical systems
Separate EICRs are more likely needed if:
- each flat has its own consumer unit
- the building contains rented flats owned by different landlords
- the communal installation is separate
- there are landlord supplies feeding shared services
- there is mixed-use or commercial space
- some parts are owner-controlled and others are building-controlled
In practice, many London blocks need a split strategy such as:
- individual flat EICRs where relevant
- one communal area EICR
- one landlord supply inspection where separate boards or systems exist
Trying to force everything into one vague inspection is usually a bad move.
The Biggest Mistake Block Management Companies Make
The biggest mistake is assuming the building is covered because some individual flats already have certificates.
That is not the same as the whole building being covered.
A block can have:
- five landlord EICRs for rented flats
- three owner-occupied flats with no inspection
- one communal lighting board never checked
- one landlord distribution board hidden in a basement cupboard
- one external lighting circuit with no recent inspection
From a compliance and risk point of view, that building is not fully covered.
Another common mistake is failing to define the scope before booking.
A block manager may ask for “an EICR for the building,” but unless somebody has clarified:
- how many boards there are
- what each board feeds
- what is communal
- what is inside private demise
- what is landlord-fed
- what is accessible
- what has previous certification
the inspection can become messy fast.
Case Study Example 1: Twelve-Flat Residential Block in South London
Let’s make this practical.
A block management company in South London manages a purpose-built building with 12 flats. Six are rented, six are owner-occupied. The block also includes:
- communal hallway lighting
- stairwell lighting
- an external front light
- a shared door entry system
- a landlord distribution board
- cleaner socket in the ground-floor lobby
- service cupboards on each floor
What the agent assumed
The managing agent believed the building was broadly covered because several landlords had already sent over flat EICRs.
What was actually found
Once the site was reviewed, it became clear that no proper inspection had been carried out on:
- the communal lighting circuits
- the landlord board
- the door entry power supply
- the external light circuit
- the lobby socket
Outcome
The building required:
- separate flat EICRs where relevant
- a separate inspection for communal and landlord-controlled installations
- remedial works to damaged accessories and poor circuit labelling
Main lesson
Flat EICRs do not automatically cover the communal installation.
This is one of the biggest misunderstandings in block management.
If issues are found, we also carry out remedial work for failed EICR certificates, helping clients move from failed report to completed compliance faster.
Case Study Example 2: Older Mansion Block in West London
Now take a different type of building.
An older mansion block in West London contains 18 flats, a basement meter area, a shared hallway lighting system, external lights, and an entry system that has been modified over the years.
What looked fine at first
The block looked well-maintained on the surface. Hallways were decorated, lighting seemed to work, and several flats had recently been sold or let.
What the inspection revealed
The communal installation had:
- poor circuit identification
- aging board accessories
- damaged blanks
- signs of older alterations
- unclear landlord supply boundaries
- outdated fittings in service cupboards
Why this matters
On paper, the building looked fine. In reality, the electrical setup in the communal parts had not been properly reviewed for a long time.
Main lesson
Visual appearance means nothing. A clean hallway does not mean the communal electrics behind it are in good condition.
Do Communal Areas Need an EICR in London Blocks?
In many cases, yes.
If the communal areas are electrically supplied and those installations are part of the building’s shared infrastructure, then they should be inspected on a proper cycle. That includes shared lighting, sockets, boards, and building-controlled supplies.
Typical communal installations needing inspection include:
- hallways
- entrance lobbies
- shared staircases
- storage rooms
- meter cupboards
- plant areas
- external shared areas
- refuse areas
- shared service cupboards
This is especially important in older London buildings where upgrades have happened over many years, often by different contractors, with mixed documentation.
What Should a Block Management Company Check Before Booking an EICR?
If you want the job to run smoothly, gather the right details first.
1. How many boards are on site?
Do not assume there is only one. Buildings often have extra boards in cupboards, risers, basements, or plant areas.
2. Are you booking for flats, communal areas, or both?
This changes the scope, access plan, time required, and reporting.
3. Is there a landlord supply?
If yes, it should be clearly identified.
4. Is the building mixed-use?
A ground-floor shop, office, or commercial space may need separate handling.
5. Are service cupboards and meter cupboards accessible?
No access means delays, repeat visits, and wasted cost.
6. Are previous reports available?
Old reports help identify history, changes, and recurring issues.
7. Are there known faults or problem circuits?
This helps electricians focus on likely trouble areas during the inspection.

Common Electrical Problems Found in London Communal Areas
This is where block management companies often get surprised.
Common issues found during communal or landlord supply inspections include:
- outdated fuse boards
- missing or poor labelling
- damaged accessories in service areas
- exposed wiring in cupboards
- loose terminations
- signs of overheating
- poor earthing arrangements
- lack of RCD protection where needed
- old lighting circuits in communal routes
- undocumented alterations
- mixed-age equipment
- overloaded landlord circuits
- broken enclosure blanks
- temporary repairs that became permanent
These are not rare. They are normal findings in a lot of older blocks, especially where upgrades have happened over time without a clear electrical asset plan.
Chart: What Usually Drives EICR Complexity in a Block?
| Complexity Level |
Typical Building Features |
Inspection Impact |
| Low |
One communal board, simple lighting, easy access |
Faster inspection, easier reporting |
| Medium |
Multiple boards, external lights, shared systems |
More planning and access coordination |
| High |
Plant rooms, mixed-use areas, landlord supplies, poor documentation |
More detailed scoping and longer inspection time |
This is why pricing and timing vary from site to site. For more guidance, see our EICR Certificate Cost page.
How a Good Block Management EICR Process Should Work
Here is the proper workflow:
Step 1: Identify the building type
Is it a simple converted house, a purpose-built block, a mansion block, or mixed-use?
Step 2: Map the electrical installation
Work out what serves private flats, what serves communal areas, and what serves landlord-controlled systems.
Step 3: Confirm responsibility
Clarify who controls each area of the installation.
Step 4: Arrange access
Flats, cupboards, risers, meter rooms, basements, roof plant, and shared spaces all need planning.
Step 5: Carry out inspection
The electrician inspects the agreed scope and records observations properly.
Step 6: Review report outcome
Satisfactory or unsatisfactory, along with coding and recommendations.
Step 7: Complete remedials if needed
Where defects are found, they should be addressed properly and documented.
Step 8: Store the records
Certificates and reports should be held centrally for future compliance tracking, handovers, and management continuity.
How This Connects to Landlords, Homeowners, and Building Managers
One reason this topic is so important is because blocks are rarely owned or occupied in one single way.
You may have:
- private landlords renting out flats
- leaseholders living in their own units
- a freeholder responsible for communal areas
- a managing agent coordinating maintenance
- an RTM company making decisions
- shared building services under landlord control
That is why your electrical compliance setup should never be approached like a single domestic house.
If your team also deals with private owners, our EICR Certificates for Homeowners in London page is useful too, especially when owner-occupiers ask where their responsibility starts and ends.
When Should Block Management Companies Arrange an EICR?
The wrong time is when:
- a resident complains
- the hallway lights keep tripping
- the fire risk assessor flags electrical concerns
- the insurer asks questions
- a solicitor asks for building safety documentation
- a hidden fault turns into an emergency
The right time is before it becomes reactive.
A planned inspection gives you:
- better access coordination
- better budgeting
- less disruption
- proper scope control
- more time to deal with remedials
Reactive electrical compliance is almost always more expensive and more stressful than planned compliance.

Final Answer: Who Is Responsible for Flats, Communal Areas and Landlord Supplies?
Here is the clean summary.
Private flats
Usually the responsibility of the flat owner or landlord of that unit.
Communal areas
Usually the responsibility of the freeholder, management company, RTM company, or whoever controls the common parts.
Landlord supplies
Usually the responsibility of the party controlling the landlord-fed installation serving shared systems or building services.
Managing agents
Often coordinate inspections on behalf of the responsible party, but responsibility depends on the legal and management structure of the building.
So the key takeaway is this:
There is rarely one single EICR responsibility for the whole block. Responsibility needs to be matched to the actual installation being controlled, supplied, or maintained.
That is the part a lot of people get wrong.
