Inspection services across the UK's most demanding industries
The most costly failures in oil and gas infrastructure rarely come from damage you can see. Corrosion developing beneath pipe supports, behind insulation, or within weld heat-affected zones can go undetected for years under standard inspection regimes — until it causes an unplanned outage, or worse.
At Sutro Group, we provide integrated oil and gas inspection services for assets across the UK and Europe. Our capability is built around finding what standard inspection misses — combining UAV surveys, rope access, advanced NDT, and robotic inspection to give operators a complete and accurate picture of asset condition.
Oil & Gas
Specialist inspection services for onshore and offshore pipeline integrity, refineries, and processing facilities. We support planned maintenance shutdowns, statutory inspection programmes, and integrity assessments across upstream, midstream, and downstream assets.
Power Generation
Inspection and access solutions for gas-fired power stations, combined cycle plants, and energy from waste facilities. Our teams work within the tight outage windows and safety protocols that power generation assets demand, delivering reliable data without unnecessary downtime.
Chemical Processing
Safe, accredited inspection for petrochemical plants, chemical manufacturing sites, and storage terminals. We operate in hazardous and restricted environments where compliance, method statement rigour, and zero-incident performance are non-negotiable.
Water & Utilities
Inspection services for water treatment works, pumping stations, and distribution infrastructure. As water utilities face increasing pressure on asset condition and regulatory compliance, our integrated approach helps maintenance teams get more from every planned inspection visit.
Managing inspection across complex industrial assets means coordinating access, testing, and reporting — often under tight maintenance windows and strict compliance requirements. Sutro Group delivers UAV inspection, rope access, NDT, and robotic inspection through one experienced team, reducing programme risk and simplifying the audit trail for asset owners across oil and gas, water utilities, power generation, and chemical processing.
Sourcing separate contractors for access and inspection creates gaps — in scheduling, in accountability, and in documentation. When one team holds the IRATA, BINDT, and CAA accreditations needed to complete the full scope, there’s a single point of contact, a single RAMS pack, and a single chain of responsibility from survey to report. For asset owners managing complex maintenance programmes, that consistency reduces the administrative burden and the risk of things falling between contractors.
In industries where asset downtime has a direct operational cost, inspection efficiency matters. Because our rope access, drone, and NDT capabilities are coordinated internally, we can sequence work across a shutdown without waiting on third-party availability — reducing total time on site without compromising inspection quality. The result is a leaner programme that makes better use of your maintenance window, with less time lost to contractor coordination.
No two assets are identical, and no single inspection method suits every situation. We assess each job on its own terms — deploying UAV where access is restricted, rope access where precision work is needed at height, robotic systems where human entry isn’t appropriate, and advanced NDT where subsurface data is required. The result is an inspection programme built around the asset, not around what a single-service provider can offer.
Asset owners in water utilities, oil and gas, and power generation operate under strict inspection and maintenance regimes. Our reporting is structured to support your compliance requirements — with full traceability, accredited sign-off, and documentation that holds up to regulatory and insurance scrutiny. Every report is produced by accredited personnel and formatted to support both internal sign-off and external audit processes.
