Quick Answers
Who is responsible for communal areas in a block?
In most long residential leases, the landlord (or RTM company) is responsible for maintaining and repairing the structure, exterior, and common parts of the building. The cost is recovered through the service charge. Individual leaseholders maintain the interior of their own flats. The precise boundary between what is communal and what is within a leaseholder's demise is defined in the lease.
Can leaseholders be charged for communal area improvements?
The service charge covers maintenance and repair to the standard required by the lease. Improvements beyond what maintenance requires can be charged through the service charge where the lease authorises them. Leaseholders can challenge improvements as unreasonably incurred at the First-tier Tribunal if the cost is disproportionate or the improvement was not authorised by the lease.
What happens if a pipe in the communal area leaks into my flat?
The RTM company or landlord is responsible for repairing the communal pipe. Buildings insurance typically covers resulting damage to the flat below. Where the landlord was aware of the problem and failed to act, they may be liable for damage resulting from that failure. Sudden, unforeseen failures are generally insurance matters rather than direct landlord liability claims.
The legal structure: a long residential lease creates a detailed allocation of responsibilities between the leaseholder and the landlord. The leaseholder takes responsibility for their demise — the interior of the flat as defined in the lease. The landlord (or RTM company, acting in the landlord's management functions) takes responsibility for the common parts and the structure. The cost of maintaining what the landlord is responsible for is recovered through the service charge, which all leaseholders contribute to in proportion to their share as set out in the lease.
Where the disputes arise: the most contested areas are always the boundaries — the things that are neither clearly inside a single flat nor clearly communal. The flat entrance door, the balcony, the internal face of external walls, the floor/ceiling junction between flats. These boundary areas are where the lease wording matters most and where disputes most often require Tribunal determination.
Key Takeaways
The lease demise plan defines the boundary between the flat and the communal areas
Every long residential lease should contain a plan identifying the demised premises — the area over which the leaseholder has exclusive possession. This plan, read together with the lease's definitions of what is included and excluded from the demise, determines exactly where the leaseholder's responsibility ends and the communal responsibility begins. A lease that grants a flat "together with the internal surfaces of the structural walls" draws a different boundary from one that grants "the flat as shown on the plan edged red excluding the structure." Read the lease, look at the plan, and read the definitions carefully.
The landlord's maintenance obligation is enforced through the implied repairing covenant
Most long residential leases contain an express covenant by the landlord to maintain and repair the structure and common parts. Where the lease is silent or ambiguous, there is also an implied obligation arising from the nature of the demise — a landlord who has retained control of the common parts has an implied obligation to keep them in reasonable repair so that leaseholders can use their flats properly. The RTM company, having taken on the landlord's management functions, takes on this obligation in the managed building.
Routine maintenance and urgent repairs must both be funded from the service charge
The service charge covers both routine maintenance of communal areas (cleaning, decoration, minor repairs) and capital works (roof replacement, lift refurbishment, structural repairs). The RTM company cannot refuse to carry out communal area repairs on the basis that there are insufficient funds in the service charge — it is obliged to maintain the building and must budget accordingly. Where the service charge is genuinely insufficient, the appropriate response is to increase contributions with adequate notice, not to defer necessary repairs indefinitely.
Flat entrance doors create the most persistent boundary disputes
The entrance door to a flat — the one that sits in the communal corridor — is one of the most frequently disputed elements in residential block management. Is it within the leaseholder's demise (and therefore their responsibility to maintain) or is it a structural element of the building (and therefore the landlord's responsibility)? The answer is lease-specific and not uniform. Some leases give the leaseholder the entrance door and its internal face; others retain the entire door structure in the common parts. Fire door replacement programmes make this boundary question practically significant and financially important.
The RTM company inherits the landlord's obligations and the landlord's liability exposure
When an RTM company exercises the right to manage, it takes on the management functions of the landlord — including the obligation to maintain the communal areas. An RTM company that fails to maintain the communal areas to the standard required by the lease is in breach of those obligations in the same way the landlord would be. A leaseholder who suffers damage from a communal area maintenance failure can bring a claim against the RTM company. RTM directors who treat communal area maintenance as optional or discretionary misunderstand the legal obligations they assumed when the RTM was established.
Improvements require separate authorisation from routine maintenance
The lease obligation to maintain and repair does not automatically confer a right to improve. An RTM company that replaces functional but old communal carpets with higher-specification flooring, or that upgrades a serviceable entrance lobby to a premium standard, may be carrying out works that go beyond what the lease authorises and that can be challenged through the service charge reasonableness route. RTM directors who want to improve the common parts beyond the maintenance standard should check whether the lease authorises this, or pass a resolution at the AGM of the company as a management decision made transparently with leaseholder involvement.
The Lease Is the Starting Point
Every question about responsibility for communal areas in a residential block begins with the lease. Not the managing agent's standard practice. Not the customs of the block over the past decade. The lease.
A long residential lease contains at minimum:
- A definition of the demised premises — the flat and any areas exclusively granted to the leaseholder
- A plan identifying the demised premises
- The landlord's covenants — what the landlord has agreed to do, typically including maintaining the structure, exterior, and common parts
- The leaseholder's covenants — what the leaseholder has agreed to do, typically including maintaining the interior of the flat, not altering the structure, and not causing nuisance
- The service charge provisions — what costs can be recovered through the service charge, how they are allocated between leaseholders, and how demands must be made
Reading these sections of the specific lease for the building is the only reliable way to answer any responsibility question. Generic advice about "typical" leasehold practice is a starting point but leases vary significantly, particularly between older and newer buildings, between different developers, and between blocks that have been individually drafted versus those using standard forms.
It is not uncommon for managing agents and RTM directors to give confident answers about communal area responsibility without having consulted the specific lease. These answers may be right — they may reflect what is typical. But they can also be wrong in ways that create significant liability. Where the responsibility question has financial consequences (a disputed repair cost, a potential liability claim, a service charge challenge), get a clear answer from the lease before acting.
The Three Responsibility Zones
Landlord / RTM Company
Structure, exterior and common parts- External walls, roof, and foundations
- Main structural elements and load-bearing walls
- Communal corridors, stairwells, and lobbies
- Communal gardens and external grounds
- Lifts and lift shafts
- Communal water supply, drainage, and service installations
- Communal electrical systems including lighting
- Bin stores, bike stores, and shared facilities
Often Disputed
Boundary elements — lease-specific- Flat entrance doors and frames
- Balconies and terraces
- Internal face of external walls
- Floor/ceiling structure between adjacent flats
- Windows and window frames
- Pipe runs and service conduits within flat walls
- Parking spaces demised to specific flats
- Storage cages or areas within communal spaces
Leaseholder
Interior of the demised flat- Internal non-structural walls and partitions
- Internal finishes: plaster, paint, floor coverings
- Kitchen and bathroom fittings and appliances
- Internal plumbing within the flat
- Window frames where granted in demise
- Internal decorations throughout
- Any items installed by the leaseholder
- Balcony furniture and non-structural elements (varies)
The Most Contested Boundary Disputes
| Element | The Dispute and How to Resolve It |
|---|---|
| Flat entrance doors | Whether the entrance door is within the leaseholder's demise or the common parts varies by lease. Many leases grant the leaseholder the flat "including the internal surface" of the entrance door — meaning the leaseholder is responsible for their side but the door structure, frame, and external face are communal. Fire door replacement programmes require clarity on this boundary because the fire door specification (the communal element) may need to change while the decoration of the inner face (the leaseholder's element) remains their responsibility. Read the specific lease clause on the entrance door before any fire door programme begins. |
| Balconies and terraces | Balconies are commonly granted within the leaseholder's demise but the structural element — the slab, the waterproofing, and the parapet wall — may remain the landlord's responsibility. A leaseholder who wants to add furniture or plant pots to their balcony is exercising rights over their demise. A leaseholder who wants the structural deck repaired should check whether that is within their demise or the landlord's maintenance obligation before making their claim. Some leases make the balcony entirely the leaseholder's responsibility including structure; others do not. |
| Windows and frames | Windows are another area where lease wording varies significantly. Some leases grant the leaseholder the window and frame and make them responsible for maintenance. Others retain windows as part of the external envelope of the building and keep them within the landlord's maintenance obligation. Where windows are the leaseholder's responsibility, their replacement is not a service charge item. Where they are the landlord's responsibility, replacement can be included in the service charge subject to the reasonableness test. |
| Pipes and service runs within flat walls | The pipe that serves a flat exclusively (a pipe that connects only to one flat's bathroom) is typically the leaseholder's responsibility from the point of entry to their flat. The main communal pipe serving multiple flats is typically the landlord's responsibility. The junction between the two — the point at which a pipe branches from the communal run to serve an individual flat — is a common source of dispute when a leak occurs. The lease often addresses this directly with a definition of where the leaseholder's installation begins and the communal installation ends. |
What the Service Charge Covers for Communal Areas
The service charge funds the cost of the landlord or RTM company meeting its obligations under the lease. For communal areas, this covers:
- Routine maintenance: cleaning, grounds maintenance, communal lighting, fire safety testing, minor repairs. These are typically budgeted annually and charged through the general service charge account.
- Reactive repairs: unplanned repairs to communal areas as they arise — a broken communal door lock, a failed communal light fitting, a blocked communal drain. Charged through the general service charge account as incurred.
- Major works: large-scale repairs or replacements such as roof replacement, external redecoration, lift refurbishment, or structural repairs. These are typically funded from the reserve fund (sinking fund) supplemented by special levies where necessary, and require Section 20 consultation for qualifying works.
- Management costs: the managing agent's fee for managing the block, including inspections, arranging contractors, accounting, and administration. Charged through the service charge as an overhead.
What the service charge does not automatically cover:
- Improvements beyond the maintenance and repair standard, unless the lease specifically authorises improvement costs to be included
- Works the landlord or RTM company is not obliged to carry out under the lease
- Costs that are not reasonably incurred — Tribunal challenge is available for service charge items that are excessive, unnecessary, or disproportionate
When a Leaseholder Causes Damage to a Communal Area
A leaseholder who damages a communal area is liable for the cost of repair. The most common scenarios:
- Moving damage: a leaseholder moving furniture scratches walls, damages door frames, or marks communal floors. The cost of making good the damage can be charged to the leaseholder rather than spread through the service charge. Where the damage is attributable to a specific leaseholder, the RTM company should document it contemporaneously, notify the leaseholder, and charge the repair cost directly.
- DIY works affecting communal areas: a leaseholder drilling through a communal wall, removing part of a shared riser, or causing damage to the structure of the building while carrying out works in their flat. These may also involve a lease breach (where the works were unauthorised alterations) and both the repair cost and the breach can be addressed through the formal lease enforcement process.
- Accidental damage from the flat: a leaseholder whose bathroom pipe fails and floods the communal corridor below, or whose washing machine overflows and causes damage to the communal entrance. Whether the leaseholder is liable depends on whether the failure was foreseeable and preventable (in which case they may be liable) or a sudden, unforeseeable event (in which case it may be an insurance matter rather than a direct liability claim against the leaseholder).
Where a leaseholder causes damage to a communal area, document it immediately — photographs, a written description of the damage, the date and time it was discovered, and any witnesses. The contemporaneous record is essential if the damage is disputed later. Send a written notification to the responsible leaseholder within 48 hours of discovering the damage, referencing the lease covenant requiring leaseholders not to damage the structure or common parts, and stating the estimated cost of repair. Keep a copy. Act quickly — late notification makes it easier for the leaseholder to claim the damage was pre-existing.
When Responsibility Is Genuinely Unclear
Despite the lease being the starting point, some responsibility questions are genuinely ambiguous after reading it. The lease may be silent on a specific element, may use wording that could support more than one interpretation, or may have been drafted in a way that creates an unintended gap in responsibility.
Options where the lease is genuinely ambiguous:
- Seek a solicitor's opinion on the correct interpretation. A property solicitor experienced in leasehold matters can advise on how the lease should be read and what the courts would likely hold if the question were litigated. This is the highest-cost option but provides the most reliable answer.
- Apply to the First-tier Tribunal for a determination. Where the question concerns whether a specific maintenance cost can be charged through the service charge, the Tribunal can determine whether the cost is a service charge item under the lease. This is a lower-cost option and produces a binding determination for the parties.
- Agree a practical arrangement between the parties. Where both the leaseholder and the RTM company acknowledge the ambiguity, a documented agreement about how a specific element will be managed going forward can be a pragmatic resolution. This does not resolve the underlying lease interpretation but prevents ongoing conflict about a specific item.
- Include the item in the service charge with a transparent explanation. In some cases, the RTM company may decide to include a disputed item in the service charge, transparently noting that the lease is ambiguous, and invite any leaseholder who wishes to challenge the inclusion to apply to the Tribunal. This puts the decision out in the open rather than making a unilateral call in the managing agent's favour.

Frequently Asked Questions
The landlord — or the RTM company in an RTM-managed block — is responsible for maintaining and repairing the structure, exterior, and common parts under the lease. The cost is recovered through the service charge. Individual leaseholders maintain the interior of their own flats. The precise boundary is defined in the lease demise plan and the lease's definitions. Where the question is contested, the lease is always the starting point — generic advice about what is typical is not a substitute for reading the specific lease.
Any part of the building and grounds not within the demise of an individual flat — including entrance lobbies, corridors, stairwells, lift shafts, plant rooms, communal gardens, car parking, bin stores, external walls, roof, and foundations. The service installations that serve multiple flats (communal water supply, drainage, electrical systems) are also typically communal. The exact boundary between a flat's demise and the communal areas is defined by the lease — the most commonly disputed elements are entrance doors, balconies, windows, and shared pipe runs.
The service charge covers maintenance and repair. Improvements that go beyond the maintenance standard can only be charged through the service charge where the lease authorises them. Leaseholders can challenge disproportionate improvement costs at the First-tier Tribunal as unreasonably incurred. RTM directors who want to improve communal areas beyond the maintenance standard should check the lease authorisation and consult leaseholders through the AGM process rather than unilaterally instructing improvement works.
The RTM company or landlord is responsible for repairing the communal pipe. The question of liability for damage to the flat depends on whether the leak resulted from a failure to maintain what was the landlord's responsibility (potentially creating direct liability) or was a sudden, unforeseen failure (typically covered by buildings insurance rather than a direct claim). Where the damage is significant, take legal advice on the specific facts and document everything contemporaneously — photographs, written notifications, repair invoices.
The leaseholder is liable for the cost of repair. The lease typically contains a covenant requiring leaseholders not to damage the structure or common parts. Where the damage is attributable to a specific leaseholder, the RTM company should document it immediately, notify the leaseholder in writing, and charge the repair cost directly rather than spreading it through the service charge. Where the leaseholder disputes liability, the matter can be referred to the First-tier Tribunal.
