NDT inspection cost in London: Radiographic Testing rates
Field-anchored pricing guide for RT (Radiographic Testing) and the other five common NDT methods in London, GB. Rates are quoted in USD per hour and reflect the Tier-4 labour band that applies across northeast markets.
London-based supermajor HQs run global inspection programs — a single quarterly audit reaches across UKCS, Gulf of Mexico and West African asset NDT records simultaneously.

Film or digital RT for new construction and in-service welds per ASME Section V and API 1104.
RT costs include source rental (Ir-192 or Co-60), film/DDA, processing, exclusion-zone setup, and radiation safety officer overhead. Night-shift premiums are common because exclusion zones can't coexist with other site work.
London's industrial substrate — Energy HQs, Engineering and consulting, Insurance / class HQs — pulls NDT scopes onto recurring sites including Shell plc HQ and BP plc HQ. The local contractor pool prices against HSE PSSR / PSR acceptance criteria, which requires Level II / III certified personnel and traceable instrument calibration. That floor — not raw wage data — is what sets the band.
The Tier-4 multiplier (×0.85 applied to the national RT base band) accounts for local cost of living, procurement competition, and the documentary overhead that HSE PSSR / PSR imposes. RT programmes in London have historically clustered around the typical rate of $595 per hour, with turnaround and outage premiums pushing toward the high band.
Recurring industries pricing against this band:
Named operators / sites: Shell plc HQ, BP plc HQ, Lloyd's Register Group HQ.
Crew rotation length
Multi-day mobilisations in London amortise travel and per-diem across more billable hours, lowering the per-hour rate. Single-day call-outs sit at the high band.
Access and rigging
Rope access, scaffold, or confined-space entry add 15–35% to the base rate. Energy HQs sites in London often require all three.
Shift premium
Night shift, weekend, and turnaround windows in London typically carry a 25–40% premium on the base hourly rate.
Acceptance criteria
HSE PSSR / PSR acceptance criteria require Level II / III sign-off, which prices above structural-weld AWS D1.1 work.
Equipment specification
Source licensing, exclusion-zone management, and night-shift premiums are the primary cost levers.
Programme volume
Multi-asset programmes at sites like Shell plc HQ typically negotiate volume discounts of 8–15% off the typical rate.
Mobilisation distance
Remote northeast sites add a per-trip mobilisation charge ($350–$1,500 depending on travel distance from London).
Documentation depth
Full digital scan packages with audit-grade traceability cost 10–20% more than basic written report deliverables, and are required at HSE PSSR / PSR sites.
- 1.Plan RT scopes against the northeast turnaround calendar to avoid rush premiums.
- 2.Batch multiple assets at the same site (e.g. Shell plc HQ) to amortise mobilisation across more billable hours.
- 3.Provide detailed component specs and accessibility info up-front — vague RFPs price high to absorb uncertainty.
- 4.Standardise on a single contractor for programme work; spot-buys carry a 10–20% premium.
- 5.Where RT is interchangeable with another method (RT ↔ PAUT, MT ↔ PT), price both before committing.
- 6.Verify Level II / III currency before quote — re-mobilisation for an expired cert is unbillable to the asset.
- •Pipeline girth welds per API 1104
- •Pressure vessel welds per ASME Section VIII
- •Casting volumetric inspection
