| Item | Category | Quantity |
|---|---|---|
| 1 | Environmental services, Auditing services, Fuels, Petroleum products, fuel, electricity and other sources of energy, Public utilities, Services related to the oil and gas industry | Not published |
Benchmarked against retained Find a Tender procedures with CPV division 09. The category anchor is Petroleum products, fuel, electricity and other sources of energy (09000000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.
| Comparison set | Procedures | Reported bids per procedure | Named award suppliers | Price evidence |
|---|---|---|---|---|
| Market: CPV division 09 | 1,169 | 3 median · 38.7 average (428 of 1,169 with a bid count) | 5.7 average (484 of 1,169 with named award suppliers) | Not published |
| Same buyer | 1 | Not published | Not published | Not published |
| Delivery region: UK | 314 | 5 median · 105.1 average (109 of 314 with a bid count) | 10 average (126 of 314 with named award suppliers) | Not published |

“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.
Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.
No planning milestones published.

"description": "Auditors to be employed to carry out Engineering asset assurance surveys and inspections at gas and electricity sites. The scope of work, for a period would be typically as follows for electricity assets:\n* Primary assets (transformers, circuit breakers > 25 years old) at ~ 20 substations supplying strategically important demand (possibly generation), including those designated Critical National Infrastructure (CNI). Estimated Time – 3 months assumed reasonable. Sites to be agreed with National Grid Electricity Transmission (NGET). DESNZ want input to this too. \nThe auditor would provide their expert view on whether NGET’s asset management policies and procedures are fit for purpose and consistent with international best practice. Whether they are following these policies and procedures correctly, in terms of the monitoring, maintenance and repair/replacement of these assets. Whether they are accurately recording these activities and making appropriate/timely interventions where issues are identified. And whether they are reporting accurately to Ofgem through Network Asset Resilience Measures (NARMs). \n2. Expanding 1 to cover 30 substations (>10% of all NGET substations as a representative sample), 4-5 months. \n3. Expanding 1 to cover a wider set of substation assets (Protection & Control, Connections / Busbars, Civil Structures, Cables, Auxiliary Systems, disconnectors/earth switches etc), ~ 6 months. \n4. Expanding 3 to cover 30 substations, say 9 months. \n5. Expanding 3 to include 10% of Overhead Lines and Cables (~800km) on heavily loaded strategic transmission boundaries. 1-2 years at a guess. \nA similar programme would likely be developed for Gas. ",
