From bulk liquid and powder disposal to tank cleaning, spill response, and confined space works, our trained teams deliver safe, compliant, and efficient solutions using specialist equipment.
Planned Preventative Maintenance
Regular maintenance of fuel storage and distribution systems is essential to ensure that they operate efficiently and without interruption. Our Service Inspections are designed to suit the specific needs of each site, and we offer annual, bi-annual, quarterly, or bi-monthly inspections depending on the requirements.
Addressing issues identified during a Service Inspection is essential to minimise unscheduled downtime and reactive callouts. In cases where issues are more complex, such as product change (uplift) for ex-gasoil tanks or new tank installation projects, we will refer clients to our Environmental Services or Design & Installation teams.
New PPM Referral Scheme
As part of our commitment to supporting long-term client relationships, OTS has launched a new PPM Referral Scheme. If you're an existing client and refer a new client who purchases a qualifying OTS fuel storage system, you’ll receive a discounted rate on your next Planned Preventative Maintenance visit.
It’s our way of saying thank you and helping you save while promoting best practices in tank service and compliance.
Qualifying purchases include new steel tanks for fuel, AdBlue, leachate or other bulk liquids designed, manufactured, and installed by OTS.
Reactive Call Outs
When it comes to fuel storage and dispensing equipment, even the slightest fault can lead to significant losses in time and money. Whether a client is in an existing service contract or not, we provide quick and efficient support to rectify any issues that may arise.
At OTS Group, we believe that reactive callouts are an opportunity to not only fix the problem but also to review the entire set up and discuss preventive measures with the Transport and Maintenance Managers on-site. This helps to minimise future faults, and as Emma Tilley, our Service and Logistics Manager, notes, "prevention is always better than a cure."
-
Transport & Maintenance Managers often call us seeking repairs such as nozzle or hose replacements, or when gauges, probes or Fuel Management Systems malfunction. We understand the importance of getting things right the first time and our First-Time Fix objective reflects this. In fact, we are proud to report that we achieve a 95% success rate in fixing issues in a single callout.
-
Our Service and Logistics Manager plays a crucial role in ensuring this success. They take detailed information over the phone about the fault and equip our service engineers with the parts that are likely to be required. If there are parts we don't have in stock, we are committed to doing "whatever it takes" to get them as quickly as possible, so we can get the job done on the first site visit. This approach not only minimises downtime but also avoids the need for diagnostic-only callouts, which can be frustrating for clients.
