The CAFM Buyer's Guide 2026 — UK edition

Most CAFM buyer’s guides are content marketing produced by one of the vendors being compared. This one is written by the founder of one of the platforms in the category, but with the explicit aim of giving you the framework to evaluate the category honestly, including the parts where Zerix isn’t the right answer.

It is structured for an FM director or estates lead who needs to defend their recommendation to a board, a Trust executive or a property owner. If you only have ten minutes, jump to The eight questions.

What CAFM is, and what it isn’t

CAFM (Computer-Aided Facilities Management) is the broad category for software that manages the operational lifecycle of buildings: helpdesk, work orders, planned preventative maintenance, asset registers, contractor governance, audits, and increasingly statutory compliance.

Two adjacent categories overlap with CAFM in the buyer’s mind:

• CMMS (Computerised Maintenance Management System): the maintenance-and-asset core. CMMS is a subset of CAFM in most modern usage.
• IWMS (Integrated Workplace Management System): CAFM plus space management, lease administration, sustainability and capital project management. IWMS is what large enterprises buy when they want one suite for everything; the trade-off is configurability and price.

For most UK estates the right answer is a focused CAFM with strong compliance, not an IWMS. The IWMS implementations we see go over budget and behind schedule with depressing regularity.

The market in 2026

UK CAFM in 2026 is segmented by deployment cost, target estate size, and stack modernity. A simplified map:

• Large enterprise / IWMS: established global vendors with broad IWMS scope. £50k–£200k+ per year, 6–24 month implementations, multi-vendor stacks, deep configurability.
• Mid-market established: UK and international CAFM vendors with long-standing market presence. £30k–£80k typical annual, 6–12 month onboarding, generally older database stacks.
• SME / point solutions: smaller UK and European vendors offering focused compliance, audit or PPM tools. Affordable, quick to deploy, narrower scope.
• Modern AI-native challenger: Zerix. Built on a modern database engine with engine-level Row-Level Security. £20k–£50k typical annual, weeks to deploy, compliance-led rather than work-order-led.

The eight questions

These are the questions we’d want a buyer to ask before signing any CAFM contract, including ours. Where we have a strong answer, we say so; where we don’t, we say so too.

1. Is the database AI-safe?

Specifically: does the database engine enforce tenant isolation through Row-Level Security policies, applied before any query reaches the application layer? If the vendor cannot describe the policies in place, every AI feature is a procurement risk. We covered why in detail in Why AI in CAFM is unsafe without RLS.

2. Is compliance a first-class module or an afterthought?

Many CAFM platforms grew out of work-order management and bolted compliance on as a custom-form module. The tell: ask whether compliance status is binary (compliant / due / expired / missing) at the data model level, or whether it’s derived from work-order completion. The first is defensible; the second is not.

3. How fast can it actually be deployed?

Vendors will quote 12 weeks. Buyers consistently land at 24+. The question to ask is which artefacts the platform supports for bulk import: CSV asset register, document ingest with AI OCR, configurable compliance categories. If the answer is “our implementation team will configure this for you”, expect months.

4. What’s the contract length and unit economics?

Three-year contracts are standard. Be wary of multi-tier per-user pricing where the headline price applies to a tier most estates outgrow within a year. Per- building pricing tends to be more honest because it scales with actual use.

5. Mobile-first, or mobile-as-an-afterthought?

If your technicians and contractors will use the platform on their phones, download the actual mobile app and try to log a job, attach a photo and sign off. The gap between “has a mobile app” and “has a mobile app engineers will use” is enormous.

6. Where does AI fit?

Three real applications of AI in CAFM in 2026 are: document ingestion (AI OCR plus natural language analysis on certificates and inspection reports), risk prioritisation (which buildings are most likely to fail next audit), and conversational data access (natural language queries on compliance state).

Marketing-AI categories to discount: “AI-generated PPM schedules” (this is a rules engine), “AI-powered dashboards” (these are SQL queries), “AI assistants for FAQs” (these are help bots).

7. How is the audit trail constructed?

Every state change, by every user, with timestamp and IP, in a tamper-evident log. The Building Safety Act regime depends on this. If the vendor describes their audit log as an opt-in feature or a reporting query, that’s a no.

8. Who built it?

Generic software vendors versus FM specialists. There is no objectively right answer (both can ship great software) but it shapes the data model and the product instincts. If the founders have not personally been responsible for compliance failures, the platform tends to be elegant and operationally naive.

The architectural traps

The shortlist heuristic

For most UK FM and estates teams in 2026, three platforms in the shortlist tells a board you’ve done the work. We’d normally suggest:

• One large enterprise / IWMSas the “in case we go big” option.
• One mid-market established as the conservative pick. Older stack, but proven in your sector.
• One modern AI-nativeas the “new architecture” option. Zerix sits here, along with others depending on scope.

Run a structured demo with each, against the same set of compliance scope questions. Score on the eight questions above. The right answer for your estate will be obvious.

Where Zerix fits: the honest version

• Strong fit: UK estates with multi-site compliance load across healthcare, education, nuclear, utilities, logistics, hospitality, property management and corporate occupier portfolios. Buyers who want AI now and are uncomfortable with legacy stacks.
• Less of a fit: very large global IWMS scope (10,000+ buildings, multiple currencies, deep CRE / lease administration). Pure construction project management. We’ll tell you to look elsewhere if you fall here.
