Oil Tank Installation and Replacement

No matter what size your tank is or the location it is in we can help. All work will be carried out to the highest standards and will comply with current legislation.

Our heating oil tank and base installation procedure starts with a free no-obligation site survey to assess your requirements where we’ll be able to advise on whether a full or partial installation is necessary and whether any existing elements may need to be modified to meet current OFTEC Regulations.

  We're ready for anything from moving your current oil tank to a new location, upgrading your old tank and using the same place, or making base adjustments so your new oil tank is fully OFTEC compliant, our team will ensure you get the most cost effective solution for your specific needs.

If you have an old steel oil tank that is showing signs of age, rusting or even starting to leak, or may be have an old plastic oil tank, it is always best to regularly keep a check on them.


Make sure that there is no whitening, cracking or splits appearing as this could in time lead to it leaking, or when checking you may also find there is a bulging or deformation of the tank.

Once we've assessed your situation and selected the tank we'll book in your installation, here's what to expect:

  We'll notify you 48 hours in advance with the time we'll arrive.

  Once we're on site we'll assess the condition of your tank and oil, the replacement process begins with emptying your old tank.

  Usable heating oil will be pumped into our holding tank, contaminated oil and water will be removed for disposal.

  We can then disconnect and remove the tank for decommissioning, we offer the option for us to take away and dispose of your old oil tank.

  If required, a paving slab base, a concrete base or block piers can be installed to accommodate the replacement tank.

  We can also supply and install fire protection for the tank, should it be required to meet the current regulations.

  Your new tank will then be positioned, connected up and clean fuel pumped into it. 

  The fuel system will be primed and we will make sure that your boiler is running again.  


The earliest you should need to replace your old oil tank is about 5 years after installation. Often it is quite a lot longer than this, much of it depends on the initial investment in the tank and how much it's used. 


This depends on the current situation, type of tank being removed and installed, whether the oil feed line needs replacing what legal requirements the task entails. A guide price for installation fees is anything from £250 to £2,000. You individual situation can be assessed for a FREE, no obligation quote.


There is a huge variety of domestic oil tanks on the market ranging from around £400 to £2,500. If you let us know your requirements and budget we can help you find the most cost-effective tank for your needs. 


We dispose of everything you no longer wish to keep. Sludge and waste water are collected from our depot. Steel tanks are taken to scrap metal recycling centres and plastic tanks to plastic recycling centres.

What our customers say...

We used CT to install a new oil tank to replace our old one. They went along on a Sunday to take a look and let us know what was required.

They quoted us the cost for the installation, which was cheaper than we were able to find elsewhere and was the price we paid. Throughout the process we were kept informed every step of the way and in the end the installation was finished to a high standard of workmanship.

I would happily recommend them to anyone needing a new oil tank. Excellent service.

The service we received from Clark (CT Tanks) when removing our old heating oil tank and advising, sourcing, and installing the replacement one has been first class and could not be faulted.

He provided thoughtful and informed advice on what replacement tank would best suit our needs and where it would need to be sited in order to conform to regulations.

All tasks were dealt with in a calm, efficient manner and the site left clean & clear. The costs involved were all very reasonable and within the quote.

I would not hesitate to recommend Clark & CT Tanks to anyone looking for a tradesman to undertake work on a heating oil tank installation.

Clark quoted super quickly (very clear and easy to understand quote and very competitive), arranged a day the following week to install our replacement 1200 litre Oil tank with extension to the plinth.

The actual installation took about 3 hours - there was no mess and he took all the old materials and tank away. Super quick and clean, I would recommend Clark to anyone for this service.

Clark fitted a new heating oil tank for me and absolutely went the extra mile to make sure I was happy with it and the location.

Such a friendly, kind and professional chap who I highly recommend. Did a brilliant job, many thanks Clark.

A very efficient and reliable service to replace and install new domestic oil tank.

Within 24hrs of contacting them a site visit had been arranged and followed up the same day with their quotation. Installation completed quickly and efficiently a few days later. I would highly recommend this company.

Pat Graham, Google Reviews

I cannot fault CT Tanks. From the quick response to a quote to the final extra mile they went. From someone who has never had to choose or think about a new oil tank before, I was put at ease by the professional way that CT Tanks advised me about the best options, dealt with all the paperwork for me and had the job done quickly and efficiently. Would recommend this company for everyone.
