Firth costs 90% more than Northgate on identical boiler jobs
Across 214 matched no-heat call-outs: £118 materials and 126 min on site versus £62 and 74 min. Same fault codes, same stock archetype - Firth fit a full valve kit where Northgate replaces a cartridge.
Replace the Worcester 28i at 12/3 Elm Court
Four repairs in six months totalling £614 against a £2,050 replacement. Failure curve says two more call-outs before March.
Excess materials pattern on damp jobs
Anti-mould paint is being booked at 2.5 litres per job against a 1.2 litre average use. 38 jobs affected this month.
Move Leith routine slots to afternoons
11 no-access events in three weeks, all before 11:00. Re-slotting removes the repeat travel and the second visit entirely.
Recognise Aileen Ferguson this month
96% first-time fix across 142 jobs and the highest savings contribution in the fleet. Her cluster-batching pattern is worth rolling out to EH14.
Wisebound removed £1,014,890 of cost from the repairs operation over the last 12 months - 18% below what the same workload would have cost on the legacy system - while returning 21,180 hours to frontline delivery and avoiding 1,298 SLA breaches.
