Section 01

Executive Summary

The total estimated margin leakage across Hartwell M&E Group is £1.87m per annum — equivalent to 4.2% of turnover being lost through operational inefficiency, missed commercial recovery, cashflow drag and administrative burden.

Key finding. The two largest leakage categories — missed commercial recovery and aged WIP — are both commercially addressable. They do not require systems investment or organisational restructuring. They require better capture, earlier notice and faster submission workflows. These are the primary targets for the Prioritised AI Opportunity Roadmap (Deliverable 03).

Category Analysis

Detailed findings across each leakage category, including root causes, evidence sources and improvement indicators.

CriticalCAT-01

Missed Commercial Recovery

£620,000 per annum · 33.2% of total leakage
£620k

Hartwell's variation log shows 142 change events recorded across 23 live contracts over the last 18 months. Of these, only 58 (41%) progressed to a formal submission. A further 47 events (33%) were noted but never formalised with a contractual notice or valuation. The remaining 37 events (26%) were logged after the commercial window had closed.

FindingDetailImpact
Late notice disciplineAverage time from change event to formal notice: 18 working days. Contractual window on 14 of 23 contracts: 10–14 days.37 events (£310k est.) time-barred or commercially weakened
Weak cause-and-effect narrativeOf 58 submitted variations, 22 (38%) were returned by the client with requests for further justification. Average resubmission cycle: 3.2 weeks.£145k in approved variations required two or more submissions
Evidence not linked to eventsPhotographs, emails and site records exist but are stored in personal folders, WhatsApp threads and email inboxes rather than indexed to the change event.Average evidence assembly time per variation: 4.5 hours
No pipeline visibilityCommercial team tracks variations in a spreadsheet updated monthly. No real-time view of pipeline value, ageing or submission status.Management unaware of £180k+ in uncommercialised events until QBR review
Root cause. The commercial team has the technical knowledge to recover these amounts. The constraint is time, structure and notice discipline — not capability. Change events are identified late because capture relies on contract managers raising them verbally, and the evidence assembly process is manual and fragmented.
CriticalCAT-02

Aged WIP & Completed-Not-Invoiced Drag

£410,000 per annum · 21.9% of total leakage
£410k

Sage 200 CVR extract shows £1.24m in WIP aged over 60 days across the contract portfolio, of which £680k has been aged over 90 days. Completed-not-invoiced (CNI) work — jobs signed off on site but not yet submitted for payment — totals £390k across 8 contracts.

FindingDetailImpact
Delayed application preparationMonthly applications are typically prepared in the final 3 days of the valuation period. Supporting documents are assembled retrospectively.Incomplete applications submitted late; deductions applied on 4 contracts
No CNI tracking processCompletion status is held in engineers' diaries and job sheets. No central log tracks the gap between practical completion and invoice submission.Average CNI-to-invoice cycle: 34 days (target: 7 days)
Disputed valuations12 valuations disputed in the last 12 months, averaging £38k each. Disputes primarily relate to missing photographic evidence or unsigned completion records.£456k in valuations delayed by an average of 6 weeks
Cashflow costWorking capital tied up in aged WIP and CNI creates an opportunity cost estimated at £32k–£48k per annum at current borrowing rates.Finance Director confirmed overdraft facility drawn specifically to cover WIP gap

Tender & Bid Admin Burden

£340,000 per annum · 18.2% of total leakage
£340k

Hartwell submitted 67 tenders in the last 12 months at a win rate of 22% (15 wins). The average tender cycle consumes 94 person-hours of estimating, commercial and technical resource. Of that, an estimated 38 hours (40%) is spent on repetitive structuring, reformatting, compliance checking and document assembly rather than value-adding commercial work.

Manual scope extractionEvery tender requires manual reading and extraction of scope items from PDFs, schedules and specification documents. No templated extraction process.8–12 hours per tender on initial scope structuring alone
Assumptions & exclusions reworkAssumptions schedules are drafted from scratch each time. The team has no maintained library of standard assumptions by contract type or client.Average 3 rework cycles per tender on the assumptions schedule
Declined opportunitiesEstimating Lead confirmed that 11 viable tenders were declined in the last 12 months due to capacity constraints during the bid production phase.Estimated pipeline value declined: £3.8m (at 22% win rate = £836k lost revenue)
QA and compliance checkingPre-submission QA is a manual checklist. Compliance responses are populated individually for each tender from the same underlying information.6–8 hours per tender on compliance and QA assembly
HighCAT-04

Invoice Blockers & Payment Deductions

£235,000 per annum · 12.6% of total leakage
£235k

Analysis of 12 months of payment certificates against submitted applications reveals £235k in deductions, disputed amounts and delayed payments attributable to incomplete evidence, missing documentation or administrative errors in the application process.

Top five blocker categories

Missing photographic evidence
£82k
Unsigned completion records
£58k
Incorrect PO references
£42k
Late application submission
£33k
Scope disputes (no spec ref)
£20k
Pattern. Four of the five blocker categories relate to evidence assembly and administrative process — not commercial disputes or scope disagreements. These are preventable with structured capture at the point of completion rather than retrospective assembly at application stage.
MediumCAT-05

Reporting & Governance Overhead

£165,000 per annum · 8.8% of total leakage
£165k

Monthly contract reports, QBR packs, board summaries and compliance submissions consume approximately 480 person-hours per month across the business. The majority of this time is spent collecting, formatting and reconciling information from multiple systems rather than analysing performance or making decisions.

Report typeFrequencyHours / cycleAnnual costStatus
Monthly contract reportsMonthly × 236.5£89,700Mostly manual
QBR packsQuarterly × 814£26,880Manual assembly
Board summaryMonthly12£17,280Semi-structured
H&S / compliance returnsMonthly8£11,520Manual data pull
CAFM / KPI dashboardsWeekly3.5£19,620Spreadsheet-based
Observation. The reporting workload is not disproportionate for a business of this size. The issue is the ratio of assembly time to analysis time. Stakeholders estimated that 70–80% of reporting effort is data gathering, formatting and reconciliation — leaving only 20–30% for actual insight, action-setting and decision-making.
MediumCAT-06

SLA Deductions & Reactive Penalties

£100,000 per annum · 5.3% of total leakage
£100k

Across 6 FM maintenance contracts, Hartwell incurred £100k in SLA deductions and client-applied penalties in the last 12 months. CAFM ticket analysis shows that 62% of deductions related to response-time failures rather than resolution failures — meaning the work was completed satisfactorily but the response or attendance evidence was missing or late.

Deduction breakdown

Response-time failures£62,000
Repeat callout charges£18,000
Evidence & reporting gaps£12,000
Missed PPM completion£8,000

Root causes identified

Attendance times not logged in CAFM at point of arrival
Response evidence relies on engineer self-reporting
Priority classification inconsistencies between helpdesk and contract

Recoverable Value Assessment

Not all leakage is equally recoverable. This section assesses which categories offer the greatest improvement potential through structured AI workflow implementation.

£708k–£970k
Estimated annual recoverable value

This represents a 38–52% reduction in current leakage through structured workflow implementation across commercial capture, tender production, reporting and invoice readiness.

Recovery estimates are conservative and assume Phase 1 implementation across 2–3 priority workflows over 12 months. These figures feed directly into the KPI Framework (Deliverable 05) and the Phase 1 Implementation Proposal (Deliverable 07).
