WORKING SAFELY NEAR HIGH PRESSURE PIPELINES
Safe working near to buried high pressure pipelines is critical to protect both people and the planet. Here we outline some good practice guidelines for those working near to high pressure pipelines when undertaking agricultural work such as fencing, clearing ditches or installing drains, as well as any other activity that could pose a risk to the pipeline’s integrity.
Britain has more than 27,000km of buried pipelines used to transport a range of products at pressures of up to 100 bar. This includes flammable and explosive products such as oil, natural gas, ethylene and petroleum as well as less obviously hazardous material such as water.
Damage to these pipelines can pose a significant risk to life as well as potentially serious environmental damage if product is released. It can also lead to prosecution by the HSE as under the Pipelines Safety Regulations Act; “No persons shall cause such damage to a pipeline as may give rise to dangers to persons.”
Prior to working in the vicinity of high pressure pipelines, other than routine agricultural activities up to 300mm deep such as ploughing, seeding or harvesting – landowners should contact the pipeline operator who will provide any guidance or advice required. Contractors and temporary staff working on the land also need to be informed of where the pipelines are to discuss and agree with them the precautions they need to take before they start work.
One area of agricultural activity that has been identified as posing a significant risk to pipelines is the installation of drainage pipes. Installing drainage often requires heavy machinery and excavating close to the pipeline’s nominal depth of 1m. To prevent risks, anyone planning works within 3 metres of a buried pipeline needs to obtain permission from the pipeline operator. This is not to prevent the works, but simply to ensure that they are undertaken safely.
The location of pipelines is normally indicated by marker posts at the edges of fields, however, be advised that marker posts can be accidentally moved or damaged and that pipelines may not run in a straight line between posts. The depth of the pipeline’s cover may also be reduced in parts, so contact the pipeline operator in advance of any works and they can visit your land to locate and mark out the pipeline and advise what activities can and cannot be done safely.
If physical contact is made with a pipeline, shut down all working machinery and remove all sources of ignition. Evacuate all people from the immediate area and if the pipeline is leaking dial 999 to inform the emergency services. Do not attempt to seal a leaking pipeline and do not attempt to extinguish the fire (if one is present).
When the area is secure, contact the pipeline operator’s emergency telephone number that can be found on a nearby pipeline marker post, or from the communications you will have had from the pipeline operator. The pipeline operator will advise of next steps and will make the area safe.
To prevent damage to buried high pressure pipelines, and any subsequent prosecutions, always contact the pipeline operator in advance of works so they can advise you of good practices, locate and mark out the pipeline and supervise works if required.

CLEARING DITCHES NEAR TO BURIED PIPELINES
With the unseasonably wet weather the UK has experienced this summer, BPA’s Landowner Services team is asking landowners to be aware of buried high pressure oil pipelines before clearing ditches.
Many farmers and landowners are taking the opportunity to clear ditches to help alleviate the potential for flooding or water damage. As part of BPA’s Know What’s Below campaign, the company regularly communicates with landowners to warn them of the risks to pipelines if the right procedures are not followed when clearing ditches along the company’s 1000km of buried oil pipelines.
Keeping watercourses well maintained benefits the community, particularly if an area experiences flooding as poorly maintained watercourses can be a nuisance, restrict access to property and can result in considerable expense and inconvenience for those that have been flooded.
Issues arise when landowners or contractors clear ditches with an excavator or other mechanical equipment as they have the potential to damage the buried high pressure oil pipelines. Farmers or other landowners looking to operate in the vicinity of buried pipelines should contact the pipeline operator in advance before starting any works.
To help ensure the best and safest outcomes for all, BPA’s lands team ask that those who are looking to undertake any works within three metres of a buried BPA pipeline:
Landowner’s responsibilities
It is also the landowner’s responsibility to ensure that contractors operating on their land comply with regulations. Working near pipelines without taking the correct precautions can have serious consequences.
BPA’s Landowner Services team is on hand and able to support landowners regarding any questions or queries that they may have. Our team is available 24/7 to offer advice and support landowners. Contact us via the website or call 0800 585 387
Know What’s Below 2023
As part if its annual ‘Know What’s Below’ campaign, each year BPA’s lands team write to more than 2000 landowners across the country asking them to confirm that their contact details are correct so the company can get in contact with them should any work need to be carried out on the buried high pressure oil pipelines that run under their land.
The communication also gives landowners the opportunity to update their contact details and acts as a reminder as to the best practice guidelines, should landowners need to work in the vicinity of the pipeline.
As part of BPA’s Know What’s Below campaign and to support the process, BPA’s lands team has developed several ways in which landowners can contact the company to ensure their contact details are correct. Not only is there a pre-paid envelope to respond to the letter but there is also an opportunity to respond via the website, via SMS or by calling the company’s freephone number.
Contacting landowners is also important as it reminds them of best practice and to contact BPA should they need to carry our works near to buried high pressure oil pipelines. Below is a list of typical activities that may require pre-notification and approval from the pipeline operator. This is not an exhaustive list of works so contact should always be made prior to works beginning.
Having improved communications channels helps ensure that both the landowner and the pipeline operator have the correct contact details should there be an emergency or if BPA’s team need to access the land to undertake emergency works.
Due to the good communications between BPA and its landowners, illegal infringements have been kept to a minimum. Pipelines in the UK are protected by The Pipelines Safety Regulations 1996 which makes it illegal to cause any damage to the pipeline intentionally or unintentionally. As such, anyone working within 3 meters either side of the pipeline should contact the pipeline operator as working near to the pipeline without contacting the pipeline operator is generally illegal. BPA advises that even if a landowner is aware of the pipeline, it is always best to contact the operator if planning works. The operator can then send someone to supervise the works at no expense to the landowner.
If you receive a letter from BPA as part of the Know What’s Below campaign, please respond even if your contact details are correct. That way we can be sure to have the correct contact information if needed. Equally if you are planning any works near to the pipeline, please remember to contact a member of the BPA team and we can help ensure all works are undertaken safely.
FACTS ABOUT BURIED PIPELINES IN THE UK
Buried underneath the UK run a network of pipelines safely and efficiently carrying a range of products (including fuel, gas and chemicals) to strategic points across the country.
BPA is responsible for managing more than 2000km of buried pipelines that carry fuel at high pressure from ports and refineries to storage and distribution points across the UK. Here we outline some fun facts about the UK’s buried pipeline network:
Did you know..?
If you have any questions about the location of a pipeline on your land or if you would like to contact a member of BPA’s team to discuss undertaking some works near to the buried pipelines, contact a member of BPA’s Lands Team on 0800 585 387.
BPA HAMPERS DELIVERED FOR CHRISTMAS
It’s that time of the year again when we draw five lucky winners to receive a Christmas BPA hamper for simply responding to our annual letter. It’s important to respond to our letters to ensure that our contact details for you are up to date so we can contact landowners in the event of an emergency or if we need to access the land to undertake essential maintenance work.
As an incentive for landowners to respond and to confirm whether they still own or have responsibility for the land under which our buried, high pressure oil pipelines run we enter all responders into a prize draw with the opportunity to win a hamper worth more than £100.
By responding, BPA can be sure to have up to date records and it also gives landowners an opportunity to inform BPA of any land changes, while also reminding them to contact BPA should they need to undertake any work in the vicinity of the buried high pressure pipeline.
There are more than 1000 km of pipelines that bisect the UK and, although designed to meet the internal pressures, are susceptible to potential damage from people inadvertently working in close proximity to them. Keeping landowners informed and aware of the pipeline also helps BPA to keep them safe from leaks caused by any unintentional damage to the pipeline.
BPA is proud to achieve market leading response rates from its landowners with nearly 75% of those landowners targeted sending their completed forms back to BPA. If there are any questions regarding keeping your details up to date or if you would like to speak to a member of BPA’s team, contact us on 0800 585 387 or email us at lands@bpa.co.uk.
Thanks again to everyone who responded and congratulations to this year’s hamper winners.
HELPING YOU TO WORK SAFELY NEAR TO BURIED OIL PIPELINES
The British Pipeline Agency Limited (BPA) manages more than 1000km of buried high pressure fuel pipelines across the UK that carry highly flammable petroleum or natural gas products at very high pressure.
The pipelines bisect the UK and, although designed to meet the internal pressures, are susceptible to potential damage from people inadvertently working in close proximity to them.
To prevent accidents the lands team at BPA works with landowners giving them advice and support should they need to carry out works in close proximity to the pipelines. In many cases the pipelines are less than one metre from the surface and this can inadvertently lead to accidents should the safety guidelines not be followed. Any damage caused to the pipeline could prove not only costly but also potentially fatal.
The buried oil pipelines bisect the country. BPA’s 1000km network includes buried oil pipelines that run from Cheshire, Staffordshire and down through Northamptonshire, Bedfordshire and Hertfordshire. BPA also manage the buried oil pipelines in around the London area and even across to East Anglia.
Every year, BPA writes to landowners to remind them of their obligations in relation to the buried oil pipelines. The team works to ensure that they have the correct contact details for landowners and tenants should they need to be contacted in the event of an emergency or if repair work needs to be undertaken.
Equally the team is also on hand to offer free advice over the phone or visit the site to help provide support and advice to those looking to operate near to the buried pipeline network. The team can identify the exact location of the buried oil pipeline and mark it out so that works can be safely carried out.
BPA is empowered to, and will, stop all works near the pipeline if it considers to be unsafe to the pipeline. Landowners are also legally required to follow the Pipeline Safety Regulations 1996 that state that no person shall cause such damage to a pipeline as may give rise to a danger to persons. Breaking these conditions can lead to prosecution.
As well as potential prosecution, damage to the pipeline could lead to environmental harm through serious pollution of soil, water and the atmosphere which is likely to lead to prosecution by the Environment Agency. The cost of repair and subsequent clean-up are typically in the region of £10m.
As such, BPA aims to work closely with landowners and tenants along its pipeline network and to offer advice and support. The team can also provide a presence on the ground and support landowners in ensuring any activities undertaken are done so in a safe manner.
If you have any questions or concerns relating to the buried oil pipeline under your land, please contact a member of the BPA team and let us assist you.
BE VIGILANT FOR SUSPICIOUS ACTIVITIES NEAR TO BURIED OIL PIPELINES
The UK has a complex network of more than 27,000Km of buried high pressure oil, gas and chemical pipelines that bisect the country safely and efficiently transporting critical supplies to key points across the country. If suspicious activities are observed near to these buried pipelines it is important to report the matter to the pipeline operator or emergency services.
Although fortunately rare, there are some instances where the buried oil or gas pipelines can attract interest from criminals who seek to tap into the supply lines to steal fuel. In addition, there are instances where unauthorised digging near to pipelines may occur.
In both instances, such activities pose a serious threat to those taking part as well as the potential for wider environmental or ecological damage. an
To help prevent against illegal tapping of pipelines or unauthorised digging, BPA works closely with its network of more than 2000 landowners asking them to keep vigilant and to report any suspicious activities seen near to BPA’s buried oil pipelines.
If they see any unusual activity or suspicious activities, simply call us on 01827 63708 and we will do the rest.
Suspicious activities can be hard to define, however we would ask landowners to contact us if they see suspicious vans parking close to the pipeline, non BPA staff or contractors taking interest in the pipeline route / marker posts or if there are signs of excavations or trenches around the pipeline. Please also inform us if you see hydraulic hoses or liquid storage containers in remote areas where they would not typically belong.
What information to provide
When contacting the lands team at BPA, it would be helpful if you could provide some of the following information:
Even if you’re unable to answer all of the above, please still contact BPA and let us know of any concerns.
To support landowners and members of the public, we have a dedicated helpline number 0800 585 387 that is operated 24/7, 365 days of the year. The team has a well-developed, regularly tested, emergency response process and is supported by specialist contractors that are in regular contact with the emergency services and regulatory bodies.
Thank you for remaining vigilant and please contact BPA’s Lands team on 0800 585 387 if you have any questions or would like to inform us of any suspicious or unusual activities along our pipeline network.
PLANTING TREES NEAR HIGH PRESSURE PIPELINES
The UK government has launched a £50 million scheme to help boost tree-planting rates as part of its fight against climate change. The new Woodland Carbon Guarantee, and other such initiatives, aim to encourage farmers and landowners to plant more trees and create new woodland to store and absorb carbon from the atmosphere in return for payments
Landowners looking to plant trees and shrubs in the vicinity of high-pressure pipelines for this, or other purposes, should be aware of best practice guidelines as plant and tree roots can cause damage to the coatings used to protect the high-pressure pipelines. This in turn could lead to damage of the pipeline itself.
Before planting any new trees or shrubs in the pipeline wayleave / easement, written permission should be obtained from the pipeline operator. Any approval granted by the pipeline operator shall be subject to retaining the rights to remove, at any point in the future, all trees, which in the opinion of a pipeline engineer, might become a risk to the pipeline and its integrity.
Guidance for planting trees near buried pipelines
The consent to plant trees will state what areas may be planted and also the type of tree. The following should act as general guidance for tree planting, based on the centre line of the pipeline:
If you are in any doubt about planting trees or if you are proposing to fell trees or remove shrubs in the vicinity of high-pressure pipelines, please contact a member of BPA’s lands team who will be able to provide further help.

MOLE PLOUGHS POSE RISK TO BURIED OIL PIPELINES
Did you know mole ploughing is one of the highest risk activities the farming community can undertake around buried pipelines?
This is because our buried high pressure oil pipelines are typically only 4ft (or just over a metre) deep, and in some cases can be shallower. To ensure safety, we advise that a minimum pipeline clearance depth of around 2ft/600mm should always be in place.
Mole ploughing is a method of installing small diameter polyethylene pipes in rural areas quickly and with minimal disruption or environmental impact. Mole ploughing allows small diameter mains and services pipes to be inserted without having to dig wide trenches by creating a narrow temporary trench for installing. The depth of the pipeline insertion can however potentially cause damage to buried high pressure oil pipelines.
So, if you are undertaking mole ploughing, make sure you contact BPA and, if necessary, the team can visit the site, check the pipeline depth and help to ensure your works are safe and there are no injuries caused. Remember that the pipeline operator needs to be contacted if you are planning to undertake works within a 80ft/25m zone around our pipelines.
Although field markers are a good indicator of pipelines under your land, remember that marker posts do not always run in straight lines and that there can be bends under the ground. To be sure, contact BPA and let us help determine the exact location of the pipeline so you or your contractors can operate safely and without risk to the public or environment.
ADVICE WHEN WORKING NEAR TO BPA’S BURIED OIL PIPELINES
Each year we write to the landowners and tenants along our network of more than 1000km of buried oil pipelines that transport fuel cross-country and at high pressure. This helps us ensure we have the correct contact details should we need to contact them in an emergency, and it also provides us with an opportunity to remind them of the support we offer and the best practice when operating near to the pipelines.
The buried pipelines are needed to supply fuel to distribution terminals and major airports across the country. Transporting fuel via buried pipelines remains the most environmentally friendly way of moving fuel, however they remain susceptible to damage if works are undertaken near them without adherence to our pipeline safety guidelines. Damage caused to the pipeline could prove not only costly but potentially fatal.
Landowners run the risk of damaging buried oil pipelines if they do not follow our advice and guidance. Pipelines don’t always run in straight lines between marker posts and so we ask landowners to contact the team if they are unsure of a pipeline’s location. We are happy to visit site and mark out the exact location of the pipeline.
The Pipeline Safety Regulations 1996 states that no person shall cause such damage to a pipeline as may give rise to a danger to persons. People are therefore asked to maintain a minimum distance of 3m from buried pipelines when installing fencing, clearing ditches or undertaking any works that may cause disruption to the ground above the pipeline.
Breaking these conditions can lead to prosecution, injury or even death. Should there be an incident, those commissioning the works (or their contractor) are responsible for any liability under the Health & Safety at Work Act 1974. Damaging a buried pipeline can also cause environmental damage whether to the soil, water and the atmosphere which is likely to lead to prosecution by the Environment Agency. The repair and subsequent clean-up costs of a pipeline incident are typically in the region of £10m.
BPA is empowered to stop all works near the pipeline if it is considered to be unsafe to the pipeline, however we recognise that works near our pipelines are often necessary and that is why our Lands Team is available to support landowners in undertaking those works safely.
Before starting any works near to pipelines, please contact BPA free 24/7 on 0800 585 387 to arrange for a free site meeting. Always Know What’s Below before starting any works in the vicinity of buried pipelines.
