Walk into any facilities management conversation and you’ll hear CAFM mentioned within minutes. It shows up in software brochures, tender requirements, procurement briefs, and job descriptions, sometimes in the same sentence as CMMS, IWMS, EAM, or BMS, with nobody stopping to explain what any of them actually mean or why the differences matter.
The facilities management software market is worth nearly $3 billion globally and growing at over 13% a year, according to Mordor Intelligence. That growth is being driven by real pressure: more assets to manage, tighter compliance obligations, the Building Safety Act’s golden thread requirements, and clients who increasingly expect digital proof of everything. For facilities teams and the contractors who service buildings on their behalf, the software they use to manage all of this isn’t a back-office detail. It’s the difference between staying on top of compliance and scrambling when an auditor arrives.
So what actually is a CAFM system? What does it do day-to-day? How does it differ from a CMMS or an IWMS? And at what point does a field service business actually need one?
That’s what this guide covers.

What does CAFM stand for?
CAFM stands for Computer-Aided Facility Management.
At its simplest, a CAFM system is software that brings the day-to-day management of a building or estate into one place. Asset tracking, maintenance scheduling, work order management, compliance records, contractor oversight. Rather than sitting scattered across spreadsheets, email threads, and paper files, a CAFM system centralises all of it.
The RIBA Smart Building Overlay 2024 describes CAFM software as enabling “asset management teams to plan, execute and monitor all activities involved in reactive and planned preventative maintenance, space and move management, asset management, operational facility services, room reservations and other customer service.”
Facilities management software tools were first developed in the late 1980s, according to Designing Buildings, initially gaining traction in healthcare, government, education, and commercial property. What has changed is what these systems can now do, and the regulatory environment that makes them necessary.

What does a CAFM system actually do?
A CAFM system is a central platform for managing the physical operation of a building or portfolio of buildings. The core functions cover:
- Work order management. Maintenance requests are raised, assigned, tracked, and closed within the system. Rather than phoning through jobs or managing requests via email, every task has a record: who raised it, when, who it was assigned to, what was done, and when it was completed. This creates an audit trail that is increasingly required for compliance purposes.
- Planned preventive maintenance (PPM). One of the highest-value functions of any CAFM system is the ability to schedule maintenance before things fail rather than after. Assets are logged with service intervals, and the system generates work orders automatically when those intervals are due. The shift from reactive to proactive maintenance reduces emergency callouts, extends asset life, and makes compliance evidence easy to produce.
- Asset management. A CAFM maintains a register of every asset under management: its location, specification, service history, warranty status, and condition. Rather than hunting through filing cabinets when an inspection is due or a contractor needs to know the make and model of a piece of kit, the information is available immediately.
- Compliance and certification tracking. Gas safety certificates, EICRs, fire risk assessments, asbestos management records, legionella checks: a CAFM system stores these documents and alerts responsible parties when renewals are due. For facilities managers with statutory compliance obligations, this function alone justifies the investment.
- Contractor management. CAFM platforms provide a framework for managing external contractors: scheduling their visits, logging the work they complete, storing their certifications and insurance documents, and tracking their performance against SLAs.
- Space and occupancy management. More advanced CAFM systems include floor plan visualisation, room booking, and occupancy tracking. This helps organisations understand how space is actually being used and make evidence-based decisions about layout, consolidation, or expansion.
- Reporting and dashboards. Real-time visibility across the estate (open work orders, upcoming PPM tasks, compliance status, contractor performance, cost per asset) without manually pulling data from multiple sources.
CAFM vs CMMS vs IWMS: what’s the difference?
The terminology here trips up a lot of people, and it’s worth clearing up plainly.
CAFM vs CMMS
CMMS stands for Computerised Maintenance Management System. In the UK, the terms CAFM and CMMS are often used interchangeably, and the distinction can be blurry. The cleaner way to think about it: CMMS is primarily focused on maintenance: work orders, preventive maintenance schedules, asset history, parts inventory. CAFM is broader, covering maintenance alongside space management, contractor oversight, compliance documentation, and strategic reporting.
As MRI Software’s UK facilities guide puts it: “A CMMS is more tactical, ensuring equipment and assets remain functional through timely maintenance. A CAFM solution is more strategic, providing insight into how facilities are used, how costs can be reduced and how sustainability goals can be achieved.”
For a maintenance team focused entirely on keeping equipment running, a CMMS may be sufficient. For a facilities manager responsible for the broader operational picture of a building or estate, CAFM is the more appropriate tool.
CAFM vs IWMS
IWMS stands for Integrated Workplace Management System. An IWMS incorporates everything a CAFM does and extends it further to cover real estate portfolio management, lease administration, capital project management, sustainability reporting, and enterprise-level financial analytics.
IWMS is an enterprise tool, designed for large organisations managing complex multi-site or multi-country estates. For most facilities management operations (a single site, a portfolio of managed properties, or a field service team maintaining third-party buildings) CAFM provides everything required without the cost and complexity of a full IWMS implementation.
Planon’s facilities management glossary summarises it neatly: “CAFM has a narrower focus for managing facilities and their physical spaces, primarily aimed at medium to small organisations.”
The short version: CMMS manages maintenance. CAFM manages facilities. IWMS manages real estate at an enterprise level.
Why CAFM adoption is accelerating in the UK
The CAFM market is growing consistently. The global CAFM market was valued at approximately $1.15 billion in 2024 and is projected to reach $1.82 billion by 2029 at a CAGR of 9.6%, according to Research and Markets. The broader facility management software market is growing faster still, at 13.3% annually, according to Mordor Intelligence.
In the UK specifically, several factors are accelerating adoption beyond simple operational efficiency.
The Building Safety Act 2022 and the golden thread
The Building Safety Act has fundamentally changed the compliance landscape for facilities managers working on or around higher-risk buildings. At its centre is the concept of the “golden thread”: a continuous digital record of building safety information that must be maintained and made available to the Building Safety Regulator throughout the life of a building.
As the Building Engineering Services Association (BESA) explains, the golden thread includes maintenance records, inspection reports, modification history, and evidence of dutyholder competence. Paper-based systems cannot meet this requirement reliably. A CAFM system that stores, structures, and retrieves asset and compliance data is now the practical mechanism for meeting the golden thread obligation.
The HSE’s guidance on storing building information and the Gov.uk golden thread guidance both make clear that accountable persons must keep this information in a structured, accessible format. For FM directors and compliance managers, “FM software platforms are now expected to support the golden thread: a continuous digital record of building information that must be maintained, updated and made available to the Building Safety Regulator throughout the life of a building,” according to Baachu Rain’s 2026 FM Software Matrix.
Statutory compliance obligations multiplying
Beyond the Building Safety Act, facilities managers in 2026 are navigating an increasingly dense compliance environment: EICRs every five years (with the rental sector EICR renewal wave now under way), fire risk assessments, asbestos management plans, legionella risk assessments, gas safety certificates, and Martyn’s Law requirements for venues above certain capacity thresholds. Each of these requires scheduling, evidence, and renewal tracking.
Managing this manually becomes untenable as the number of assets, buildings, and certificates under management grows. The right software turns compliance from a reactive scramble before audits into a continuous, automated process.
Shift from reactive to preventive maintenance
Emergency callouts cost far more than planned visits. Equipment failure disrupts operations and can create liability. Asset lifespans extend when they receive timely attention rather than crisis intervention. The numbers make preventive maintenance hard to argue against.
That shift from reactive to proactive maintenance is what planned preventive maintenance actually delivers at scale. Without the right tools, maintenance schedules exist on spreadsheets or in someone’s head and they slip. With them, the system generates work orders, assigns them to engineers or contractors, and tracks completion automatically.
Do you actually need a CAFM system?
CAFM is often associated with large corporate estates or facilities management companies managing dozens of buildings. But the operational problems it solves apply at much smaller scale.
If you manage maintenance across a portfolio of properties, employ or contract engineers to carry out that maintenance, hold compliance certificates that require renewal, and need to demonstrate compliance to clients, regulators, or insurers, you’re looking at a practical operational tool rather than an enterprise luxury.
Field service businesses carrying out planned and reactive maintenance on behalf of clients face the same logic. The ability to log assets at client sites, schedule return visits automatically, store certificates, and provide clients with compliance reports is what separates a professionally run operation from one dependent on manual processes.
As SFG20 notes in their CAFM guide: “By centralising all of the important physical aspects of facility management on one unified platform, a CAFM can provide you with the tools and insights you need to make data-driven decisions, strengthen communication and boost productivity.”
Signs you might need one:
Your engineers spend time chasing paperwork rather than completing jobs. Compliance certificate renewals are tracked via calendar reminders or spreadsheets. You find out an asset needs attention when it fails rather than before it fails. Clients ask for compliance evidence and producing it takes hours. Your team can’t tell you at any given moment which assets are due for service.
Signs you probably don’t need a full CAFM:
You manage a single site with a small number of assets and a tight team. Your compliance obligations are simple and easily handled manually. You do primarily reactive, one-off work rather than ongoing planned maintenance.
CAFM and field service management
For field service businesses in heating and HVAC, electrical, pest control, and fire and security, the functional overlap between CAFM and field service management software is real and worth understanding.
The operational functions are nearly identical: asset tracking at customer sites, scheduling of planned and reactive jobs, engineer assignment and completion records, compliance certificate storage and reporting. The difference is perspective. CAFM is typically used by the facilities manager receiving the service; field service management software is used by the contractor delivering it.
For a field service business, a job management platform with planned maintenance scheduling, asset tracking, mobile forms for on-site certification, and customer-facing compliance reporting does much of what a CAFM system does, from the contractor’s side of the relationship.
Fieldmotion’s planned maintenance module automates recurring job scheduling across a client base. The asset management feature maintains a full service history against each asset. Mobile forms capture compliance certificates on site. And reports and dashboards give both your team and your clients visibility of compliance status across their estate.

FAQs
What does CAFM stand for?
CAFM stands for Computer-Aided Facility Management. It refers to software that centralises the management of a building or estate — covering asset tracking, maintenance scheduling, compliance documentation, contractor management, and reporting in a single platform.
What is the difference between CAFM and CMMS?
CMMS (Computerised Maintenance Management System) focuses specifically on maintenance — work orders, preventive maintenance schedules, asset repair history, and parts inventory. CAFM is broader, covering maintenance alongside space management, compliance tracking, contractor oversight, and strategic reporting. In the UK, the two terms are sometimes used interchangeably, but CAFM typically implies a wider operational scope. For teams whose primary concern is keeping equipment running, a CMMS may be sufficient. For facilities managers responsible for the broader operational picture of a building, CAFM is the more complete tool.
What is the difference between CAFM and IWMS?
An IWMS (Integrated Workplace Management System) incorporates everything a CAFM does and extends it to cover real estate portfolio management, lease administration, capital project management, and enterprise-level financial analytics. IWMS is designed for large organisations managing complex multi-site or multi-country estates. For most facilities management operations — a single site, a managed property portfolio, or a field service team — CAFM provides sufficient functionality without the cost and implementation complexity of a full IWMS.
Is CAFM software only for large organisations?
No. CAFM is often associated with large corporate estates, but the problems it solves apply at smaller scale too. Any organisation that manages maintenance across multiple assets or properties, holds compliance certificates that require renewal, employs or contracts engineers to carry out maintenance, and needs to demonstrate compliance to clients or regulators can benefit from CAFM software. Smaller, cloud-based CAFM and field service management platforms have made this kind of functionality accessible to businesses that couldn’t have justified the cost of legacy enterprise systems.
What does a CAFM system cost?
Costs vary significantly by system complexity, user count, and deployment model. Entry-level cloud-based systems start from a few hundred pounds per month. More comprehensive enterprise platforms can cost thousands of pounds monthly, with additional implementation and training costs. On-premises deployments involve larger upfront investments in software licences and hardware. Most organisations implementing CAFM report a positive return on investment within 12–18 months, primarily through reduced emergency maintenance costs, better asset lifecycle management, and time saved on compliance administration.
How does the Building Safety Act affect the need for CAFM?
The Building Safety Act 2022 introduced the concept of the “golden thread” — a continuous digital record of building safety information that must be maintained and accessible throughout a building’s life. For facilities managers working on higher-risk buildings, this makes a structured digital system for storing and retrieving asset data, maintenance records, inspection reports, and compliance certificates a legal requirement rather than a best-practice recommendation. Even for facilities managers not directly in scope of the Act, the golden thread principle is increasingly expected by clients and insurers as a standard of professional practice.
What is planned preventive maintenance and why does it matter?
Planned preventive maintenance (PPM) is the practice of carrying out maintenance tasks on a scheduled basis — before assets fail — rather than responding to breakdowns after the fact. PPM reduces emergency callout costs, extends asset lifespans, improves safety, and makes compliance evidence easy to produce. A CAFM system delivers PPM by automatically generating work orders when service intervals are due, assigning them to engineers or contractors, and tracking completion. Without a system to automate this, maintenance schedules tend to slip as reactive demands take priority.
What is the difference between CAFM and field service management software?
CAFM is typically used by facilities managers to manage the buildings and assets they are responsible for. Field service management software is used by the contractors and engineers who carry out maintenance work on behalf of clients. The functional overlap is significant: both track assets, schedule planned and reactive jobs, manage engineers, and store compliance records. For a field service business delivering planned maintenance across a client base, a job management platform with asset tracking, PPM scheduling, mobile forms, and compliance reporting fulfils a similar purpose to a CAFM system — from the contractor’s side of the relationship.
