Compliance and Technical Sales (CATS)

Rather than waiting for costly issues to arise, plan Preventative Maintenance into your fuel storage budget. This gives you greater control over your annual fuel storage solution spend – and, let’s face it, no one wants to be surprised with costly remedial actions when systems fail. Arranging ‘Planned Preventative Maintenance’ (PPM) is easy with our experienced Compliance and Technical Sales (CATS) colleagues, who are on hand and ready to advise on the best course of action.

Our CATS team has a full understanding of the Oil Storage Regulations and can advise on all pollution control measures for your site.

FSS understands Emergency Power Supply System (EPSS) systems (which includes UPS – Uninterruptible Power Systems – and back-up generators) and the need for the consistent supply of clean fuel to back-up generators. We know that the majority of generator ‘fail to start’ or ‘shutdown’ issues are related to inconsistent clean fuel supply to the prime mover. The best way to save money and downtime is an annual check on your fuel tanks, pumps and filters by our registered OFTEC engineers. We also take fuel samples to check your fuel against the ISO 4406 cleanliness code. This will evaluate the risk of the filters becoming blocked during an engine run.  If there’s a risk, we can clean your fuel.

Contact our CATS team to initiate these checks safely and efficiently with minimal disruption to your day-to-day operations.

The CATS team doesn’t stop at PPM. Our experts are at the other end of the phone for all compliance and technical queries. They ensure that your fuelling installation functions as you need – when you want. In addition, they liaise with all FSS departments so your experience is thorough and efficient.

Got an emergency? They can arrange an emergency call out to get you back to work in the minimum of time.


Our Operations team is at the heart of our business.

They work with you to ensure that our engineers’ arrival on site runs smoothly, right down to timing and accessibility. They will liaise with your site personnel to arrange access, provide documentation and make sure that all H&S is covered. The team also ensure that services and products arrive at the correct time. Every detail is taken care of, resulting in the seamless delivery of your job.

Our engineers are not the only thing Operations looks after. They carry out route planning to ensure the minimal environmental impact of our vehicles on the road. Essentially, Operations takes care of the finer details, so you don’t have to.


Our onsite Engineering teams travel up and down the UK and Ireland fulfilling our clients’ fuel storage needs. Our experienced, highly trained engineers deal with all fuel storage-related activities. By choosing FSS qualified specialists, you will benefit from years of combined expertise in solving industry-relevant challenges. We are there for you, taking the necessary action to ensure your fuel storage installations are well-maintained and reliable.

Working with our engineers is easy and requires minimal invested time from you. Your job is managed by a CATS or Project team member. This initial point of contact, along with Operations, ensures that your engineer arrives on-site, equipped with the correct information, and ready to get to work. Our colleagues are highly trained in health and safety regulations, reporting, and how to liaise with your team and their CATS or Project counterparts. It’s all in a day’s work for the FSS engineering team. Our bespoke reporting app allows us to deliver your site report in minutes, rather than days.


For specialist projects that require detailed quotations, technical drawings, systems and designs, you can rely on the expertise of our Project team.

We understand that many projects start with a client concept that needs to be refined into a workable, cost-effective plan. We have decades of combined experience in realising such complex projects from our office and on-site. If you need a team that can carry out planning, design, surveying, and buying (and everything else in between) we can help.

We always offer the best solution based on your initial ideas and needs.  That isn’t always the most expensive option! Our knowledgeable team understands the art of collaboration and offer honest, innovative ideas to get your project off the ground in a safe and environmentally considerate way. We also aim to help you to save money whilst meeting legal requirements.

The Projects team can give you options from a basic solution through to gold standard.
