Why Your Oil Tank Needs Cleaning

Over years of use, oil tanks accumulate sludge at the bottom — a mixture of water, dirt and degraded fuel that reduces efficiency and damages boilers. Left untreated, sludge causes blocked filters, pump failures and expensive boiler breakdowns.

MPD Tanks provides professional oil tank cleaning across Essex — from Colchester and Chelmsford to Braintree, Brentwood and beyond. We remove all contamination safely, leaving your tank clean, dry and refilled with fresh fuel.

How We Clean Your Oil Tank

Our tank cleaning service follows a thorough, safe process to ensure the best results:

01

Pump Out & Assess

We pump all existing oil from your tank into a temporary storage vessel, then assess the level of sludge and contamination inside.

02

Internal Clean

We tilt and agitate the tank to break up settled sludge, then vacuum out all contaminated material, leaving the interior clean.

03

Inspection & Report

While empty, we inspect the tank walls, seams and fittings for corrosion or damage, and provide a written condition report.

04

Refill & Test

We filter the removed oil back into your cleaned tank (if still serviceable), top up if required, and test the full system.

Does Your Tank Need Cleaning?

Watch out for these signs that your oil tank has a contamination problem:

  • Boiler cutting out or losing pressure unexpectedly
  • Black or cloudy oil in the fuel filter
  • Unusual smell from the boiler or tank area
  • Blocked fuel filters needing frequent replacement
  • Reduced boiler efficiency and higher fuel bills
  • Water in the fuel line or filter bowl
  • Tank is more than 5–7 years old and never been cleaned

⚠ Don’t Wait Until Your Boiler Fails

Sludge and water contamination is one of the leading causes of boiler breakdowns in oil-heated homes. A professional tank clean costs far less than an emergency boiler repair or replacement. If your boiler has failed and your tank has never been cleaned, the tank should be your first investigation.

Frequently Asked Questions

Do you clean oil tanks in Colchester, Chelmsford and Braintree?

Yes. We cover the whole of Essex, including Colchester, Chelmsford, Braintree, Witham, Halstead, Maldon and Saffron Walden, and the villages around them. Give us your postcode and we will confirm.

The filter keeps blocking and the oil looks dark. Is that contamination?

Very likely. Dark, cloudy or gritty oil in the filter bowl, or water you can see, means sludge or water has reached the tank outlet. Changing the filter treats the symptom; cleaning the tank removes the cause.

I am buying a house in Essex with an oil tank. Should I get it looked at?

Yes, before you complete if you can. A house survey rarely looks closely at the tank. We can tell you whether it is bunded, what condition it is in and whether it is likely to need cleaning or replacing soon, which is useful when you are agreeing a price. Ask the seller for the OFTEC installation certificate as well.

Do I need to be at home while you clean the tank?

We need access to the tank and its fittings, which are outside, so you do not have to stay in. The heating has to stay off while the tank is empty, and we will let you know when the oil is back in and it is safe to run the boiler again.
