Practice · PFI & long-term FM contracts Read the contract the way it is actually operated.

PFI is a 25-year contract in which specialist contract knowledge naturally concentrates with the operator. Authority teams turn over; operator commercial leads do not. Trellum sits with the authority team, reading the payment mechanism from first principles against recorded service events, so the authority sits in quarterly reviews with the same depth of understanding as the people across the table.

{/* THE PROBLEM PRECISELY */}
The condition

The contract was written in 2004. The team has turned over three times.

PM schedules run anywhere from 50–500 pages of defined terms, availability logic, and deduction calculations. Most estates teams inherited them.

The audit reads the schedule against the organisation's recorded service events — helpdesk logs, BMS availability data, PPM records — and returns a register of where contractual deduction entitlement and reported position diverge.

Practice · Residential block management BSA golden thread — built for the moment someone asks to see it.

The Building Safety Act introduced a statutory duty-holder regime over higher-risk residential blocks. Managing agents, RMCs and RTMs carrying HRBs now operate against an evidence standard most organisations were never asked to build. Trellum reads the information requirements against the records the organisation holds and produces the register, model and process that the Accountable Person carries into a safety-case review.

The regulatory step-change

The BSA raised the standard for the entire delivery chain. Everyone is operating against the same new regime.

Under the Building Safety Act 2022 and the Higher-Risk Buildings regulations, the Accountable Person is legally responsible for assessing and managing building-safety risks — and for demonstrating compliance, in evidence, to the Building Safety Regulator.

Most RMCs, RTMs and managing agents inherited the statutory duty-holder regime without the accompanying infrastructure. Existing management agreements were drafted for operational service delivery, before the BSA set the evidence standard that now applies to the same work.

Approach A practitioner advisory for organisations inside the built environment — not consulting to it.

Trellum is an expert practitioner. It is built on experience from a sequence of roles that together cover the built environment from the point of transaction to the point of digital operation.

Trellum is built on operational depth and commercial expertise — on having held the contract, the compliance duty, and the digital tooling requirements together, not as separate disciplines.

The four layers Four layers. Each built on the one before. The career history is not generalist. It is four compounding layers of expertise that almost no one in the built environment advisory market carries simultaneously. {[ ['01', 'Commercial', 'Sales, lettings, property management, leasehold block management, FM business development. Understanding built environment assets as commercial objects — valuation logic, yield, occupancy, stakeholder relationships. Critically: experience on the sell side of FM contracts. What procurement directors care about. What gets promised versus what gets delivered.'], ['02', 'Technical', 'Estate management within regulated industries, water treatment, civils and groundworks operations. Hard engineering in regulated, process-critical environments where failure has legal and environmental consequence. Operating plant under statutory permit. Understanding what compliance means when the stakes are material, not theoretical.'], ['03', 'Contractual', 'PFI FM, complex outsourced FM operations, multi-party contract and compliance management. Reading and operating against payment mechanisms, service standards, lifecycle obligations, and performance monitoring regimes. Managing contractors who are also reporting counterparts.'], ['04', 'Digital', 'AI tooling, software development, AI adoption programmes built for the people using them, and automation pipelines. Production capability — building working systems rather than specifying them. Led in a live environment.'], ].map(([n, t, b], i) => (
{n}
{t}
{b}
))}
What the combination produces A full-lifecycle view of the built environment — from transaction to digital operation. The career behind Trellum followed the built environment as a system across its lifecycle — from the point of transaction, through occupancy and compliance management, through hard engineering, to contract-governed operation — and the digital systems and frameworks Trellum has built sit on that arc. That full-lifecycle view is what lets Trellum see FM problems that specialists in any one layer cannot.
Method How every engagement runs. {[ ['01', 'Read the contract', 'The clause is the fact. Advisory without contract literacy is decoration.'], ['02', 'Evidence over assertion', 'Every claim is backed by document, schedule, register, or timestamp.

Not slide decks filed after the meeting.'], ['04', 'Role-specific', 'A helpdesk operator and an AP duty-holder do different jobs. Their tooling should too.'], ['05', 'Practitioner voice', "Senior FM people. Trellum has sat on the client's side of the table. The writing reflects it."], ['06', 'Teams kept capable', 'Leave the client able to maintain the framework after the engagement closes.
