Interceptor Maintenance
CSG provides interceptor maintenance services for commercial and industrial organisations across the UK, supporting businesses with planned servicing, inspections, fault identification and ongoing preventative maintenance.
Fuel and oil interceptors, need regular inspection and servicing to maintain effective operation. Keeping your interceptor system properly maintained is one of the simplest ways to reduce pollution risk, avoid operational disruption and help prevent more costly problems further down the line.
Planned maintenance helps keep interceptors operating effectively while reducing the risk of drainage failures and environmental incidents.

How Does Our Interceptor Maintenance Service Work?
Tell us about your interceptor system, site location and any faults or servicing requirements. We’ll discuss access arrangements and agree a suitable maintenance scope, which may include system inspections, functional checks, alarm testing and planned servicing.
We’ll then arrange an interceptor maintenance visit around your site’s requirements. Our team will assess the system, carry out the agreed work and explain any findings. Where further attention is needed, we’ll recommend suitable repairs, replacement parts or follow-up work.
Interceptor emptying and cleaning can be arranged alongside maintenance where required. Let us know if you need both so we can include the appropriate services in your quotation.

Frequently Asked Questions About Our Interceptor Maintenance Services
What does interceptor maintenance include?
While the exact scope will depend on the type of interceptor you have and site requirements, our maintenance plans can include:
- System inspections
- Functional checks
- Alarm testing
- Servicing visits
- Identifying faults or defects
- Planned preventative maintenance support
- Recommendations for repairs or further works where required
Is interceptor maintenance the same as interceptor emptying?
No. Interceptor emptying and cleaning focuses on removing waste, sludge and contaminated water from the system.
Maintenance is more focused on checking the condition and operation of the interceptor itself, including alarms, components and overall system performance. Need both? We can help with both! Get in touch with our team if you’d like to arrange interceptor services tailored to your site.
Do you remove the interceptor contents as part of maintenance?
Not always. Maintenance visits may involve inspection and servicing work only. Where required, interceptor emptying and cleaning can be arranged alongside maintenance works as part of a combined service visit. Let us know if that’s something you’re interested in and we can provide you with a quote.
What problems can maintenance help resolve?
Regular maintenance can help identify issues and reduce the likelihood of them becoming larger (and more costly) operational issues over time. Here are some of the most common issues we see:
- Faulty alarms
- Build-up affecting performance
- Mechanical defects
- Electrical issues
- Poor system operation
- Early signs of blockage or overflow risk
Do you offer planned preventative maintenance schedules?
Yes – we can create a planned preventative maintenance (PPM) programme around your site’s needs.
My interceptor alarm is sounding - what should I do?
An activated alarm needs prompt assessment. Follow your site procedures and contact CSG so the cause can be investigated and any necessary emptying, servicing or repairs arranged.
Environment Agency guidance identifies alarm activation as a trigger for emptying and servicing your interceptor – Find out more
Can maintenance reduce how often we need cleaning or emptying?
Maintenance helps identify defects and establish when emptying is needed. Inspection and servicing do not remove accumulated waste, so cleaning and emptying must still follow site conditions, waste levels and manufacturer guidance.
Can you provide RAMS or site paperwork before attendance?
Yes. Where required, we can provide RAMS and supporting site documentation ahead of planned maintenance visits.
Do you carry replacement parts or source components?
Our engineers may carry certain commonly required components depending on the nature of the visit.
Where specialist parts or replacements are needed, we’ll advise on sourcing the components and next steps following inspection.
How often should an interceptor be inspected and serviced?
Routine inspections should be scheduled at least every six months, in line with British Standards guidance. Higher-risk sites may need more frequent checks, and the programme should also reflect the manufacturer’s instructions and site conditions. A separate integrity test is recommended at least every five years.
Emptying and cleaning may be needed between visits if oil or silt builds up, an alarm activates or a spill occurs. We can help agree a suitable inspection and servicing schedule for your site.
Will I receive an interceptor maintenance report?
We’ll confirm the maintenance records and reporting included when preparing your quotation. If you need a written inspection report, service record or specific audit documentation, please tell us before the visit so we can agree your requirements.
Our team will explain the findings and any recommendations for repairs or further work.
