Reactive Maintenance in Flats: A Complete Guide
Everything you need to know about reactive maintenance flats procedures, costs, and processes. This guide explains what reactive maintenance means in the context of blocks of flats, how it differs from planned maintenance, what a professional reactive maintenance service looks like, and how your managing agent handles unexpected repairs. Whether you are a leaseholder trying to understand your reactive maintenance contracts, a director overseeing building management in the UK, or simply want reactive maintenance explained, this guide covers it all.
What Is Reactive Maintenance?
Reactive maintenance is the process of repairing or replacing a building component after it has already failed, broken down, or been damaged. Unlike planned maintenance, which schedules works in advance to prevent deterioration, reactive maintenance responds to problems as they occur. In the context of a block of flats, this covers everything from a burst pipe flooding a communal hallway to a failed door entry system leaving the building insecure overnight.
The term is sometimes used interchangeably with "breakdown maintenance" or "corrective maintenance" in the reactive maintenance construction industry. The core principle is the same: something has gone wrong, and a repair is needed now rather than at a scheduled point in the future. In residential block management, reactive maintenance flats work is triggered when a resident reports a defect, a contractor discovers a fault during a routine visit, or an emergency occurs that demands immediate attention.
Every block of flats will require some level of reactive maintenance, no matter how thorough the planned maintenance programme. Storms damage roofs without warning. Pipes corrode and burst between inspection cycles. Vandals damage communal areas unpredictably. The measure of a well-managed building is not whether reactive repairs occur but how quickly and efficiently they are handled when they do. A competent managing agent will have robust systems for receiving defect reports, categorising urgency, instructing approved contractors, and recovering costs through the service charge or insurance.

Common Reactive Repairs in Blocks of Flats
While every building is different, certain types of reactive maintenance flats repairs occur more frequently than others. Understanding the most common issues helps leaseholders and directors anticipate potential problems and evaluate whether their managing agent is handling repairs effectively. Below are the six most frequently reported categories of reactive maintenance in residential blocks across the UK.
- Burst pipes and plumbing failures - Burst communal risers, failed stopcocks, leaking header tanks, and fractured waste pipes are among the most common and most damaging reactive repairs in any block of flats. A single burst pipe can cause water damage to multiple flats, affecting ceilings, electrics, decorations, and personal belongings. Prompt isolation and repair are critical to minimising the extent of damage and the resulting cost. These events often trigger a claim under the block's buildings insurance policy for escape of water.
- Broken door entry systems - Intercom and access control systems are heavily used and frequently targeted by vandals. A failed entry system compromises the security of the entire building and is treated as an urgent reactive maintenance matter. Repairs may involve replacing handsets, reprogramming access panels, or replacing the entire system where repeated failures indicate the equipment has reached the end of its serviceable life.
- Failed communal lighting - Lighting failures in hallways, stairwells, car parks, and external areas create health and safety risks and must be addressed promptly. Under health and safety legislation, communal areas must be adequately lit to ensure safe passage for residents and visitors. Emergency lighting failures are particularly urgent because they affect fire escape route illumination. For ongoing communal area issues, see our communal repairs service page.
- Lift breakdowns - Lifts are complex mechanical systems that can fail without warning despite regular servicing. A lift breakdown causes significant inconvenience, particularly in buildings with elderly or disabled residents who cannot use the stairs. Lift repairs require specialist engineers and can be costly, especially if parts need to be sourced from the original manufacturer. Reactive lift repairs are a substantial component of annual reactive maintenance expenditure in buildings with passenger lifts.
- Roof leaks - Storm damage, blocked gutters, failed flashings, and deteriorated felt or membrane can all cause water ingress through the roof. Roof leaks are a common trigger for reactive repairs and, if left unresolved, can lead to extensive internal damage including ceiling collapse, timber decay, and mould growth. Temporary weatherproofing may be needed while a permanent repair is planned. For urgent roof issues, our emergency repairs team can arrange immediate attendance.
- Vandalism and accidental damage - Broken windows, damaged fencing, graffiti, smashed lighting, and forced entry to communal areas all require reactive repair. Vandalism is unpredictable by nature and can only be addressed after the event. Where vandalism is persistent, the managing agent may recommend additional security measures such as CCTV, improved lighting, or upgraded access control as part of a broader approach to reducing the volume of reactive maintenance calls.
Recognising these common issues helps residents report problems clearly and quickly. The faster a defect is reported to the managing agent, the sooner it can be resolved and the less likely it is to cause secondary damage that increases the overall repair cost.
Reactive vs Planned Maintenance
Understanding the difference between reactive maintenance and planned maintenance is fundamental to good building management. Both are necessary, but they serve different purposes and have different cost implications for leaseholders.
Planned maintenance is proactive. It involves scheduling works in advance based on manufacturer recommendations, condition surveys, and cyclical programmes. Examples include exterior redecoration every five years, annual boiler servicing, gutter cleaning twice a year, and fire safety equipment testing. Because the work is planned, it can be budgeted for in the annual service charge, competitively tendered, and carried out at a time that minimises disruption to residents. Planned maintenance extends the life of building components, reduces emergency callouts, and keeps overall costs lower over time.
Reactive maintenance is unplanned. It responds to failures and defects as they occur. Because the work is urgent, it often attracts premium labour rates, out-of-hours call-out charges, and higher material costs due to the need for immediate availability. Reactive repairs may also reveal secondary damage that would not have occurred if the underlying issue had been caught through a planned inspection. For example, a small roof leak that goes undetected for months can lead to timber rot, ceiling damage, and mould growth, turning a minor repair into a major remediation project.
The 80 20 rule in maintenance provides a useful framework for understanding the relationship between these two approaches. Industry experience suggests that approximately eighty per cent of reactive repair calls originate from around twenty per cent of building components. By focusing planned maintenance investment on those high-failure components, a managing agent can significantly reduce the volume and cost of reactive maintenance. This principle is central to efficient building management and is a key consideration in any well-structured reactive maintenance contract.
The most effective maintenance strategy for any block of flats combines both approaches. A comprehensive planned maintenance programme reduces the need for reactive repairs, while a well-organised reactive maintenance service ensures that unavoidable failures are dealt with swiftly, cost-effectively, and with minimal disruption to residents. Neither approach works well in isolation. Buildings that rely exclusively on reactive maintenance deteriorate faster and cost more to maintain over time, while even the best planned programme cannot anticipate every possible failure.
How Your Managing Agent Handles Reactive Repairs
A professional managing agent is responsible for receiving, assessing, and resolving all reactive maintenance flats issues efficiently and transparently. The quality of your agent's reactive repair procedures directly determines how quickly problems are resolved and how well costs are controlled. At Block, our reactive maintenance service follows a structured five-stage process that ensures every repair is handled to a consistently high standard.
Stage 1: Reporting and Logging
Residents report defects by telephone, email, or through our online portal. Every report is logged with a unique reference number, a description of the issue, the date and time it was reported, and the reporter's contact details. This ensures a clear audit trail from first report through to completion and enables the agent to track response times and contractor performance across all reactive maintenance jobs.
Stage 2: Urgency Assessment
Each reported defect is assessed and categorised by urgency. Emergency repairs that pose an immediate risk to health, safety, or security are escalated for same-day attendance through our emergency repairs process. Urgent but non-emergency repairs, such as a partial heating failure or a contained leak, are targeted for resolution within one to three working days. Routine reactive repairs that do not present an immediate risk are scheduled within a reasonable timeframe, typically up to twenty-eight days depending on contractor availability and the nature of the work.
Stage 3: Approved Contractors
We instruct repairs through a vetted panel of approved contractors who cover all relevant trades including plumbing, electrical, glazing, roofing, joinery, and specialist lift engineering. Every contractor on our panel is fully insured, holds the appropriate trade qualifications, and has agreed to our response time standards and pricing framework. Using a panel of pre-approved contractors means we never waste time searching for a tradesperson when a reactive maintenance issue is reported, and leaseholders benefit from competitively negotiated rates established through our reactive maintenance contracts.
Stage 4: Cost Recovery
The cost of reactive maintenance is recovered through the mechanism most appropriate to the circumstances. Routine reactive repairs are funded from the annual service charge budget, which includes a contingency allowance for unplanned works. Where the repair cost is substantial, it may be funded from the building's reserve or sinking fund. If the damage is attributable to a specific leaseholder, the cost may be recharged directly to that individual under the terms of the lease. Where the damage results from an insured peril, we manage the insurance claim process from notification through to settlement.
Stage 5: Completion and Review
Once a reactive repair is completed, the work is inspected where appropriate, the contractor's invoice is checked against the agreed scope and price, and the job is closed on our system. We analyse reactive maintenance data regularly to identify recurring issues that may indicate a need for investment in planned maintenance or component replacement. This feedback loop between reactive maintenance and planned programmes is how well-managed buildings progressively reduce their reactive repair burden over time.
If your current managing agent does not operate a structured reactive maintenance service, or if you are experiencing slow response times and poor communication on repairs, it may be time to consider a change. A building without efficient reactive repair procedures is a building where small problems become expensive emergencies.

Frequently Asked Questions About Reactive Maintenance in Flats
What does reactive maintenance include?
Reactive maintenance includes any repair or remedial work carried out in response to an unexpected failure, fault, or defect that has already occurred. In a block of flats, reactive maintenance typically covers burst pipes, failed communal lighting, broken door entry systems, lift breakdowns, roof leaks following storm damage, vandalism to communal areas, blocked drains, faulty fire alarm panels, broken windows in shared areas, and emergency plumbing repairs. The defining characteristic of reactive maintenance is that the work is unplanned and triggered by an event rather than scheduled in advance. A professional managing agent will have systems in place to receive reports of defects from residents, assess the urgency of each issue, instruct approved contractors, and oversee the repair through to completion. Reactive maintenance costs are typically recovered through the annual service charge or, where the cost is significant, through the building's reserve fund or insurance policy.
What is a reactive approach to maintenance?
A reactive approach to maintenance means waiting until something breaks or fails before carrying out a repair. Rather than scheduling work in advance to prevent deterioration, the reactive approach responds to problems as they arise. In block management, a purely reactive approach means that the managing agent only arranges repairs when a resident reports a fault or a contractor identifies a failure during a visit. While reactive maintenance is unavoidable for genuinely unpredictable events such as storm damage, vandalism, or equipment failure, relying solely on a reactive approach is widely regarded as poor practice. Buildings managed on a purely reactive basis tend to suffer from higher overall repair costs, more frequent disruption to residents, accelerated deterioration of building elements, and lower property values. The recommended approach is a balanced maintenance strategy that combines a structured planned preventative maintenance programme with efficient reactive maintenance procedures for unexpected issues.
What is the difference between planned maintenance and reactive maintenance?
Planned maintenance is work that is scheduled in advance according to a programme, carried out at regular intervals to prevent deterioration and extend the life of building components. Examples include cyclical exterior redecoration, annual boiler servicing, gutter cleaning, and fire safety equipment testing. Reactive maintenance is work carried out in response to an unexpected failure or defect that has already occurred, such as a burst pipe, a broken entry system, or a roof leak after a storm. The key difference is timing and predictability. Planned maintenance is proactive and budgeted for in advance, while reactive maintenance is unplanned and often more expensive because the failure may have caused secondary damage. Both types of maintenance are essential in a block of flats. A well-managed building will have a comprehensive planned maintenance programme that reduces the frequency and severity of reactive repairs, but no programme can eliminate reactive maintenance entirely because some failures are genuinely unpredictable.
What is the 80 20 rule in maintenance?
The 80 20 rule in maintenance, sometimes called the Pareto principle applied to building management, suggests that approximately eighty per cent of maintenance problems come from twenty per cent of building components or systems. In practice, this means that a relatively small number of elements in a block of flats are responsible for the majority of reactive maintenance calls. Common culprits include ageing plumbing systems, door entry systems, communal lighting, and flat roof sections. Understanding the 80 20 rule allows a managing agent to focus planned maintenance investment on the elements that generate the most reactive repairs. By proactively maintaining or replacing the twenty per cent of components that cause eighty per cent of the problems, the overall volume and cost of reactive maintenance can be significantly reduced. This principle underpins the argument for a balanced approach that combines planned preventative maintenance with efficient reactive repair procedures.
What are the costs of reactive maintenance?
The costs of reactive maintenance are typically higher than the equivalent planned maintenance because emergency or urgent repairs attract premium labour rates, out-of-hours call-out charges, and expedited material costs. There is also the risk of secondary damage, for example a burst pipe that is not caught early can damage ceilings, electrics, and decorations in multiple flats, significantly increasing the total repair bill. In a block of flats, reactive maintenance costs are recovered through the service charge and shared between all leaseholders according to the proportions set out in the lease. Where the cost of a single reactive repair is substantial, it may be funded from the building's reserve or sinking fund. If the damage is caused by an insured peril such as storm, flood, or escape of water, the cost may be recoverable under the block's buildings insurance policy. Leaseholders have the right to request a summary of reactive maintenance expenditure as part of their annual service charge accounts.
What are the advantages of reactive maintenance?
The primary advantage of reactive maintenance is that no money is spent until a repair is actually needed, which avoids the cost of maintaining components that may still be in good working order. For genuinely unpredictable failures such as storm damage, vandalism, or sudden equipment malfunction, reactive maintenance is the only practical response. Reactive maintenance also allows managing agents to prioritise spending based on actual need rather than a theoretical schedule, which can be beneficial for buildings with limited budgets. However, these advantages are limited and do not outweigh the benefits of a structured planned maintenance programme. Buildings that rely too heavily on reactive maintenance typically spend more overall because emergency repairs cost more than planned works, failures cause secondary damage, and building elements deteriorate faster without proactive care. The most effective approach for any block of flats is a combination of planned preventative maintenance to reduce failures and a well-organised reactive maintenance process to handle issues that cannot be anticipated.
