Managing a multi-unit residential building comes with significant financial and legal responsibilities. Among the most critical is ensuring the property is adequately protected against costly structural damage, unexpected liabilities, and complex operational risks. Navigating block of flats insurance can be challenging, especially when balancing freeholder obligations, leaseholder expectations, and mortgage lender requirements.
Whether you are a freeholder, a Residents' Management Company (RMC) director, a Right to Manage (RTM) company, or a property manager, securing the right policy is about more than checking a box; it's about safeguarding your asset, avoiding devastating underinsurance penalties, and maintaining smooth operational cash flow.
In this guide we break down exactly what a comprehensive block of flats buildings insurance policy covers, where individual leaseholder responsibilities begin, and how to eliminate hidden coverage gaps before a major claim occurs.
How Buildings Insurance Works for Blocks of Flats
Buildings insurance is universally mandated by commercial mortgage lenders, bank covenants, and the specific terms of UK leasehold agreements. Because a block shares a structure, communal areas, and facilities such as passenger lifts and underground parking, a single buildings insurance policy covers the entire block rather than each flat individually.
This type of insurance is designed for properties with multiple dwellings sharing communal areas, shared facilities, and a single freehold or management structure. For the highest level of financial protection, policies are often written on an "All Risks" basis. "All Risks" cover is the broadest form of buildings insurance available; instead of only covering named perils such as fire or flood, it covers any accidental loss or damage to the building unless explicitly excluded in the policy wording.
This article focuses strictly on what is covered rather than who pays or how much it costs, serving as a handy checklist to compare against your own policy wording and schedule.
Who Usually Arranges Buildings Insurance for a Block of Flats?
Knowing who arranges the block insurance matters because it determines who controls the cover, who dictates policy terms, and who pays for it. Traditionally, freeholders take on the core responsibility. However, when leaseholders exercise the legal right to take over management via a Right to Manage (RTM) company, the RTM company assumes full responsibility for purchasing the block's buildings insurance directly. Alternatively, a Residents' Management Company (RMC), share of freehold owners, or appointed managing agents may handle procurement.
Individual flat owners rarely arrange separate buildings cover for just their own unit; instead, leaseholders typically pay for buildings insurance through service charges collected by the freeholder, RTM, or management company. Mortgage lenders usually require proof that sufficient insurance is in place for the whole building, covering the full rebuild cost, before releasing funds.
Beyond finance compliance, comprehensive buildings insurance makes the property far more appealing to potential tenants and buyers, proving that the block is actively and professionally managed.
Structural and Communal vs Individual Leaseholder Cover
The table below sets out the typical demarcation between the block buildings policy and an individual leaseholder's own contents insurance.
| Category | Block buildings insurance | Leaseholder insurance |
|---|---|---|
| Building structure | Foundations, external walls, roof, chimneys, load-bearing internal walls, floors, ceilings, staircases, balconies | Internal non-structural decorations, fixtures not permanently attached |
| Permanent fixtures | Fitted kitchens, bathrooms, built-in wardrobes, fixed flooring, radiators, permanently wired lighting, plumbing, wiring | Furniture, appliances, personal possessions, internal decorations |
| Communal areas & facilities | Entrance lobbies, corridors, stairwells, lifts, shared balconies, bin stores, bike rooms, plant rooms, communal gardens | , |
| External features | Garages, boundary walls, car ports, fences, gates, paths, driveways, fixed play equipment in communal grounds | , |
| Underground services | Pipes, drains, cables serving the block, including communal risers | Individual flat plumbing beyond the communal risers |
| Engineering and statutory inspections | Lifts, boilers, pressure vessels, automatic gates (insurance and inspection coverage may be separate) | , |
| Alternative accommodation & loss of rent | Temporary housing costs and rent loss for flats made uninhabitable by insured events | , |
Buildings insurance for blocks of flats often includes cover for engineering and statutory inspection risks, such as Lifting Operations and Lifting Equipment Regulations (LOLER) inspections for passenger lifts, boiler and pressure vessel checks, and liability insurance for automatic gates, although these may be managed as separate policy extensions.
Trace-and-access costs for sudden, unforeseen damage, such as locating hidden leaks behind walls or within communal risers, are typically included. Accidental damage caused by contractors during general maintenance or refurbishment works is also covered, provided poor workmanship is not the root cause. Finally, alternative accommodation cover and loss of rent protection safeguard cash flow by covering temporary housing costs and rental income loss if a major incident renders the flats uninhabitable.
What Is Not Covered by Buildings Insurance in a Block of Flats?
While buildings insurance, even on an "All Risks" basis, provides broad protection, it excludes damage arising from general wear and tear, corrosion, gradual deterioration, or fungal decay, as these are considered maintenance issues rather than insurable events. Defective design, poor workmanship, and any pre-existing damage before policy inception are also excluded, placing responsibility on property owners and management to ensure proper construction and upkeep.
Deliberate damage caused by residents or criminal acts committed by the insured party is excluded, as is cyber-related interference with building systems, reflecting the evolving nature of risks in modern properties. Furthermore, unoccupied flats beyond specified periods, commonly 30 to 60 days, are often excluded or subject to restrictions, requiring notification to insurers.
Importantly, personal possessions, furniture, and internal decorations fall outside the scope of buildings insurance and must be protected under separate contents insurance policies.
What Individual Leaseholders and Tenants Need to Insure Themselves
Individual leaseholders depend on block buildings insurance to cover the structure and permanent fixtures of the building, but they must arrange their own contents insurance to protect their personal belongings. This includes furniture, appliances, and other possessions within their flats, as well as internal decorations such as paint, wallpaper, and carpets, unless the lease specifies otherwise.
Accidental damage cover for personal belongings and electronics is also the responsibility of the leaseholder or tenant. Additionally, tenants should consider tenant's liability insurance to cover potential damage they might cause to someone else's property within the building. For those renting flats, securing contents insurance and tenant's liability cover is essential to ensure adequate protection beyond what the block insurance provides.
Setting the Right Buildings Sum Insured and Avoiding Underinsurance
Determining the correct buildings sum insured is crucial as it must reflect the full cost of rebuilding the property in the event of a total loss. This comprehensive figure includes not only demolition and site clearance expenses but also professional fees incurred for architects, surveyors, and engineers involved in the restoration process, along with debris removal costs.
Underestimating this value can lead to underinsurance, which often results in claim payments being reduced proportionally through average clauses. To avoid this, it is advisable to conduct regular professional reinstatement cost assessments, typically every three to five years or following significant building works, ensuring that the sum insured remains accurate and sufficient to cover the rebuilding costs.
Liability, Legal Expenses and Other Linked Covers
Buildings insurance for blocks of flats often integrates additional protections beyond physical damage. Property owners' liability insurance is essential to cover claims arising from injuries or property damage occurring in communal areas, safeguarding landlords, freeholders, and management entities against potential lawsuits.
If staff such as caretakers, concierges, cleaners, or gardeners are employed directly, employers' liability insurance is also required to cover workplace injuries or illnesses. Legal expenses insurance provides valuable support for disputes related to the property, including boundary disagreements or conflicts with contractors.
Furthermore, directors' and officers' liability cover protects board members of Residents' Management Companies (RMC) or Right to Manage (RTM) organisations from claims arising from their management decisions, ensuring comprehensive financial protection for those responsible for the building's upkeep.

Frequently Asked Questions
Does my buildings insurance cover damage caused by contractors working in the block?
Cover may include accidental damage caused by contractors if the peril is insured. Contractors should maintain their own liability insurance. Deliberate damage, foreseeable damage, and poor workmanship are excluded and claimable against contractors' insurers. For major refurbishment, additional contract works and liability cover may be needed.
Are internal decorations in my flat covered by the block buildings policy?
Typically, block insurance covers structural elements and permanent fixtures. Internal decorative finishes such as paint, wallpaper, and carpets are usually excluded and fall under leaseholder contents insurance, but lease agreements vary. Confirm with your managing agent or broker.
Does buildings insurance cover short-term lets like Airbnb within a block of flats?
Most block insurance policies assume standard residential use and may exclude or restrict cover for short-term or holiday lets. Landlords must disclose short-term letting to the freeholder or property manager, who should notify insurers to maintain cover validity.
What happens if my block is partially unoccupied?
Insurers impose conditions if vacancy exceeds certain thresholds, such as enhanced security and inspection regimes, and may restrict escape of water cover. Notify your broker promptly to adjust terms and avoid claims issues.
If I improve my flat, do I need to tell the building insurer?
Leaseholder improvements may not automatically increase the block buildings sum insured. Expensive upgrades should be disclosed to the managing agent, RTM director, or insurer to confirm coverage or arrange additional insurance as needed. Structural alterations require freeholder or RMC notification and possible policy adjustment.
