Identifying where admin burden, missed commercial recovery, WIP, invoice blockers and reporting drag are creating cost and capacity issues across the business.
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.
| Leakage category | Annual estimate | % of total | Severity |
|---|---|---|---|
| Missed commercial recovery | £620,000 | 33.2% | Critical |
| Aged WIP & CNI drag | £410,000 | 21.9% | Critical |
| Tender & bid admin burden | £340,000 | 18.2% | High |
| Invoice blockers & deductions | £235,000 | 12.6% | High |
| Reporting & governance overhead | £165,000 | 8.8% | Medium |
| SLA deductions & reactive penalties | £100,000 | 5.3% | Medium |
| Total estimated leakage | £1,870,000 | 100% |
How the £1.87m breaks down across each category of operational and commercial loss.
Detailed findings across each leakage category, including root causes, evidence sources and improvement indicators.
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.
| Finding | Detail | Impact |
|---|---|---|
| Late notice discipline | Average 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 narrative | Of 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 events | Photographs, 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 visibility | Commercial 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 |
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.
| Finding | Detail | Impact |
|---|---|---|
| Delayed application preparation | Monthly 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 process | Completion 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 valuations | 12 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 cost | Working 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 |
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.
| Finding | Detail | Impact |
|---|---|---|
| Manual scope extraction | Every 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 rework | Assumptions 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 opportunities | Estimating 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 checking | Pre-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 |
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.
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 type | Frequency | Hours / cycle | Annual cost | Status |
|---|---|---|---|---|
| Monthly contract reports | Monthly × 23 | 6.5 | £89,700 | Mostly manual |
| QBR packs | Quarterly × 8 | 14 | £26,880 | Manual assembly |
| Board summary | Monthly | 12 | £17,280 | Semi-structured |
| H&S / compliance returns | Monthly | 8 | £11,520 | Manual data pull |
| CAFM / KPI dashboards | Weekly | 3.5 | £19,620 | Spreadsheet-based |
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.
| Response-time failures | £62,000 |
| Repeat callout charges | £18,000 |
| Evidence & reporting gaps | £12,000 |
| Missed PPM completion | £8,000 |

Not all leakage is equally recoverable. This section assesses which categories offer the greatest improvement potential through structured AI workflow implementation.
| Category | Annual leakage | Estimated recovery | Recovery value | Confidence | Timeline |
|---|---|---|---|---|---|
| Missed commercial recovery | £620,000 | 40–55% | £248k–£341k | High | 6–9 months |
| Aged WIP & CNI drag | £410,000 | 35–50% | £144k–£205k | High | 3–6 months |
| Tender admin burden | £340,000 | 30–40% | £102k–£136k | High | 3–6 months |
| Invoice blockers | £235,000 | 45–60% | £106k–£141k | Medium | 6–9 months |
| Reporting overhead | £165,000 | 50–65% | £83k–£107k | High | 3–6 months |
| SLA deductions | £100,000 | 25–40% | £25k–£40k | Medium | 9–12 months |
| Total recoverable range | £1,870,000 | 38–52% | £708k–£970k | ||
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).
