Our diesel services
Four services, one point of contact
Choose the service that matches the problem, or enquire above and we will work out the right one with you. Each page covers how the visit works, what you get and the questions we hear most.
Fuel testing
Diesel fuel testing & sampling
On site checks and laboratory analysis that show what is in your tank today: water, sediment, microbial growth and fuel condition, before they turn into a breakdown.
Best forStandby generators, annual compliance checks and any fuel you have not tested in a while.
Fuel testing service
Diesel bugDiesel bug treatment
Microbial contamination clogs filters, corrodes tanks and stops engines. We confirm it, clear it and treat the fuel so it does not return.
Best forRepeat filter blockages, slime or dark sludge in samples, and fuel that has sat for a year or more.
Diesel bug service
Fuel servicingFuel servicing & polishing
Mobile filtration circulates the fuel through staged filters and water separation, so a contaminated tank returns to a clean, usable spec without draining it.
Best forWater, particulates and sludge in bulk, day and generator tanks, as a one off or a scheduled contract.
Fuel servicing page
DecommissioningFuel tank decommissioning
When a tank is redundant, we empty it, clean it and make it safe, then remove it or leave it properly sealed, with the paperwork you need for your records.
Best forSite closures, tank replacements, fuel changeovers and tanks that no longer meet regulations.

Which service do I need?
Start with what you are seeing
Most calls begin with a symptom, not a service name. This is where we usually point people.
What you are seeing
Where to start
Fuel has not been checked for a year or moreStandby generator, boiler or vehicle tank
Fuel testing
Filters keep blocking, or there is slime in the sampleOften a sign of microbial growth
Diesel bug treatment

Fuel polishing

Tank decommissioning
On every visit
What you can expect from any diesel service
Whichever service you book, the same standards apply on site and in the paperwork you are left with.
Minimal downtime
We plan the work around your site, and most visits keep the tank in service for as long as it is safe to do so.
Waste handled properly
Contaminated fuel, water and sludge leave site with the correct documentation, so nothing is left for you to dispose of.
Common questions
Before you enquire
If your question is not here, put it in the enquiry form and we will answer it when we call.
Do you cover the whole of the UK and Ireland?
Yes. Tell us the site postcode in your enquiry and we will confirm the earliest visit date for your area.
Can I combine services in one visit?
Often, yes. Testing alongside polishing or bug treatment is common, because the sample tells us how the fuel needs to be treated and shows the result afterwards.
Do you work on HVO and gas oil as well as diesel?
We do. Mention the fuel type and tank size in your enquiry so the engineer arrives with the right equipment.
Is this a one off or can it be scheduled?
Both. Many customers book a one off clean up first, then move to a regular testing and polishing schedule for standby tanks.
