Our London FM team is SFG20-aligned, SafeContractor and CHAS accredited, ISO 9001 (quality), ISO 14001 (environmental) and ISO 45001 (health and safety) procedures-aligned, and ISO 41001:2018 (FM management systems) aware. 

TFM, IFM, Bundled, Single-Service, What’s the Difference?

The FM industry uses several terms for what is broadly the same idea one contractor delivering multiple FM services under one agreement. The terms are often used interchangeably, but the structural differences matter.

Total Facilities Management (TFM)

A single contractor delivers all hard and soft FM services under one master contract with a single annual contract price covering everything in scope. The simplest commercial model one invoice, one helpdesk, one accountability point. TFM contracts are typically priced on a fixed annual fee with limited variation. The contractor takes the risk of unforeseen reactive call-outs within an agreed envelope.

Integrated Facilities Management (IFM)

Similar to TFM but typically with a stronger management-system integration, common technology platforms, shared data, integrated reporting across services, and stronger outcome-based KPIs. IFM is often the right model for larger, more complex estates where consistent reporting and integrated data matter more than the simpler commercial structure of TFM.

In practice, J SONS & CO. and most contemporary FM providers blur the distinction we deliver under one master contract with integrated technology and reporting. The label matters less than the actual delivery structure.

Bundled Service Contract

Two or three FM services bundled under one contract  typically hard FM + cleaning, or hard FM + security. Cost-effective for clients who want to consolidate the most-coordinated services without committing to a full TFM agreement.

Single-Service Contract

One specific service under one contract typically HVAC PPM, building fabric maintenance, or cleaning. Common for clients who retain other FM services in-house or have existing contracts they don’t want to disturb.

Which Model Is Right for You

What’s Actually in an FM Contract

Hard FM Services (Technical and Engineering)

The technical scope that keeps the physical building functional, safe and compliant.

Soft FM Services (Support Services)

The day-to-day services that keep the building usable.

Helpdesk

The single point of contact for everything FM-related across the contract. Phone, email, web portal and mobile app intake. 24/7 for emergencies, working hours for non-urgent jobs. Every job logged, prioritised, dispatched, tracked, and closed out with photographic evidence. KPIs measured against SLA at every stage.

Reporting

Monthly client report covering:

• PPM visits completed vs scheduled
• Reactive call-outs by trade, priority and response time vs SLA
• Statutory compliance status what’s due, what’s overdue, what’s certified
• Asset condition flagging what’s degrading, what’s near end-of-life
• Energy and consumption data
• Recommendations for capital works or upgrade investments

Quarterly business review (face-to-face) and annual asset condition review and contract renewal proposal.

Mobilisation  How We Take Over an Existing Contract or Set Up a New One

The 30–60 days between contract signature and first day of steady-state operation. This is where most FM contracts succeed or fail.

Days 0–7: Asset Register and Survey

Every asset in scope surveyed and entered into our job-management platform. Manufacturer, model, age, condition, last-serviced date, refrigerant charge (where applicable), service history captured. Photographs of every major asset.

Days 7–14: PPM/AMC Schedule and Compliance Baseline

PPM/AMC schedule built against SFG20 (london).

Days 14–21: Helpdesk and Reporting Setup

Helpdesk number provisioned. Web portal and mobile app provisioned for the client. Monthly reporting template configured. Account manager and site team named and introduced.

Days 21–30: First Service Visits and Familiarisation

First PPM/AMC visits delivered, site teams familiarise with building, escalation routes confirmed, KPI baselines measured for the first month.

Days 30–60: Steady-State Transition

Contract operates at steady state. Daily and weekly KPIs measured. Any handover issues from previous contractor resolved. Monthly report issued. First quarterly business review scheduled.

Takeover from Existing Contractor

We’ve taken over FM contracts from every major UK. FM provider over the past decade. We carry out a documented takeover survey of every asset photographed, condition-rated, with pre-existing faults logged. From that baseline we mobilise the contract. This protects both sides: you get a documented starting record, we are not liable for pre-existing issues we didn’t cause.

Multi-Site Portfolio FM

The biggest single structural advantage we offer is integrated FM across London under one master contract.

Single Master Contract, Full London

International clients with operations in both cities run consolidated FM contracts with us. One master contract, regional account managers, aligned SLAs across both markets, consolidated monthly reporting, single quarterly business review covering both markets, volume pricing across both estates.

Aligned Specifications Across Sites

Portfolio clients hotel groups, restaurant chains, retail brands, financial services firms, get standardised FM specifications across every site, in both markets. Same SLA targets, same compliance documentation format, same reporting platform, same KPI structure. The benefit: portfolio-wide visibility instead of site-by-site reconciliation.

Sectors That Benefit Most

• Hedge funds and family offices with London 
• International law firms and professional services
• Hotel groups (London)
• Restaurant and retail chains with branches across the UK.
• Banks and financial services firms with London City presence
• Embassies and diplomatic premises
• Multi-country charities and NGOs

How It Works Commercially

One master service agreement, with regional schedules covering each city’s specific scope. One annual contract value broken down by market, by site, by service line. One consolidated invoice (or split invoicing if the client’s accounting structure requires it). Single account manager as the primary client interface, with regional FM managers in London delivering day-to-day operations.

Why Clients Choose J SONS & CO. for FM

Genuine under one master contract. No equivalent integrated provider operates this way at our scale. International clients with London operations get one contract instead of two.

Mid-market commercial focus. Most enterprise FM operators (Mitie, OCS,,) prefer £5m+ contracts. J SONS & CO is structured for mid-market £50k to £2m annual in London. The whitespace between domestic small businesses and enterprise-scale players.

Single contractor across fit-out and FM. The contractor that built or refurbished your space is the contractor that maintains it. No transition gap, no documentation loss, no warranty friction. Most FM operators don’t do fit-out; most fit-out contractors don’t do ongoing FM. We do both.

Hard FM and soft FM in-house. HVAC, MEP, building fabric, fire safety, statutory compliance, cleaning, waste, pest control all delivered by J SONS & CO. Specialist services (lifts, security, catering) sub-contracted under our main contract with KPIs flowing back through us.

Direct-employed engineers and operatives. Not agency labour. Quality, programme, accountability stay with us across both markets.

SFG20-aligned in London

 Documentation that satisfies regulators, insurers, auditors and dilapidations surveyors not boilerplate.

Transparent pricing. Per-property, per-sqft and per-line-item pricing published. Statutory compliance bundle priced separately and clearly. No mystery line items, no padded provisional sums.

Sensible technology, not vendor lock-in. Asset register, PPM scheduling, helpdesk, reporting on industry-standard platforms. If you leave us at the end of a contract, you take your data with you.

24/7 emergency response. Real 24/7 in London during summer (15 April – 15 October) for hospitality, healthcare, retail, cold chain and pharma. London after-hours response for PPM contract clients.

KPI- and SLA-driven, not effort-driven. Performance measured against outcomes. Persistent underperformance triggers root-cause analysis and corrective action not just more activity reporting.

Frequently Asked Questions

What is Total Facilities Management (TFM)?

TFM is a model where a single contractor delivers all hard and soft FM services under one master contract with a single annual fee. The simplest commercial structure for clients who want one invoice, one helpdesk, one accountability point. J SONS & CO. operates TFM as our default delivery model.

What’s the difference between TFM and IFM?

In practice the terms are used interchangeably. Both describe one contractor delivering integrated FM services under one contract. IFM typically implies stronger management-system integration (common technology platforms, integrated data, outcome-based KPIs). TFM typically implies a simpler bundled structure. J SONS & CO. operates with integrated technology and outcome KPIs regardless of label.

How much does an FM contract cost in London?

PPM-only contracts: small commercial (under 200m²) £2,400–5,500/year, mid-size (200–800m²) £6,500–18,000/year, large (800–3,000m²) £18,000–55,000/year. Full TFM (hard + soft): roughly 1.5–2.5× the equivalent PPM-only contract. Per sqft: £2–5.50/sqft for PPM-only, £5.50–18/sqft for TFM, £18–35/sqft for premium TFM. Full pricing in the London section.

How long does FM contract mobilisation take?

30–60 days typically. Days 0–7 asset register and survey. Days 7–14 PPM/AMC schedule and compliance baseline. Days 14–21 helpdesk and reporting setup. Days 21–30 first service visits and familiarisation. Days 30–60 steady-state transition. Larger contracts and multi-site portfolios may take 60–90 days.

What is the difference between FM and building maintenance?

Building maintenance is the trades and repair work fabric repair, joinery, plumbing repair, minor electrical, drain clearance. Facilities management is the broader operational contract coordinating building maintenance + HVAC + cleaning + fire safety + statutory compliance + helpdesk + reporting under one agreement. FM contracts include building maintenance scope plus a lot more.

How do you report performance?
