Border Control Post Location

The border control post would be located on land at Parc Cybi, Holyhead. The site lies to the south-east of the Roadking Truckstop off the existing service road used by a number of HGVs. The site provides convenient transport links with nearby access to/from the Port of Holyhead and the A55 linking with mainland Wales.

Community Updates


The Welsh Government Minister for Economy has appointed the contractor for the design stage of the proposed Border Control Post at Parc Cybi.

During this stage the contractor will work with Welsh Government to produce detailed designs for the facility, confirm a cost and timetable. For more information see here.

Construction work on the proposed site at Plot 9, Parc Cybi, Holyhead will not start until the build stage of the contract is agreed, expected in the summer 2022. The build stage is also subject to the granting of planning permission via a Special Development Order (SDO) – a decision is expected in May 2022.


The views of individuals and organisations on the proposals during a public consultation during March-April 2021 have been recorded in a consultation engagement report published here. All comments have been taken account of and used to inform the planning process.

Officials have drafted a more general update on the progress of the Parc Cybi Border Control Post here, and provided a concept plan for how the build will look – please be aware this plan is subject to change. Any changes will be within the Consenting Envelope, which limits the size and scope of the Border Control Post as explained in the progress update and the FAQs below.


The Department is currently working through all feedback received from the community and undertaking relevant surveys at the site. We are continuing to work with key stakeholders to develop our design, ahead of submitting any planning application to Welsh Ministers for review.


The Welsh Government is progressing plans for the use of land it owns at Parc Cybi, known as Plot 9, Holyhead as a border control post. Part of the site has already been developed using a temporary permission under Permitted Development Rights to facilitate an emergency HGV stacking facility required as a result of the end of transition period.

At Holyhead inspections would be required on goods such as animals, plants and products of animal origin entering Wales from the Republic of Ireland. These checks are the responsibility of the Welsh Government. There is currently insufficient space within the port to process the future checks required. 

A functioning border control post is vital in supporting the long-term operation of the port.

The Welsh Government’s proposed use of the site would require approval, which it is seeking under the requirements of a Special Development Order (SDO) under section 59(3) of the Town and Country Planning Act 1990.

The Welsh Government has reviewed the options for use of the site and based on current planning, expect to seek permanent use of the site under the SDO. The SDO application seeks a permanent consent for a border control post, setting out the development parameters of both the construction and operational stage of the facility. In the case that a border control post is no longer required at the site, any change of use or subsequent development of the site would require a Town and Country Planning Act application to the Local Planning Authority, Isle of Anglesey County Council.

Scheme details

  • On average, around 25-30 HGVs are expected at the site throughout every 24-hour period.
  • Employment opportunities would be created for local people.
  • Safe access would be provided for pedestrians and non-HGV vehicles at the site.
  • The Parc Cybi site is already allocated by the Local Planning Authority for commercial development.
  • The site would operate 24/7, with security marshals at the site at all times.
  • Approximately 75 employees expected at the site over a 24-hour period, including approximately 10 marshals required to safely manage vehicles and pedestrians within the facility.
  • Approximately 75 staff car parking spaces will be made available.
  • Separate inspection shelters would be provided for consumable and non-consumable produce, small animals, large animals and horses.
Indicative 3D Border Control Post


The border control post would consist of separate inspection facilities for plant produce, small animals, large animals and horses. Office buildings would be up to two stories tall and inspection buildings would be large enough to facilitate all HGV sizes.

Site staff would include fully trained security personnel and emergency response staff. Closed Circuit Television (CCTV) and Automatic Number Plate Recognition (ANPR) cameras would be positioned across the site to monitor site activities. Secure perimeter fencing would also be installed.

After entering the site, HGVs would visit the Vehicle Entry Check Point before being directed to a vacant HGV space. From there, the HGVs would undertake customs and transit checks as required. During processing, HGV drivers must remain at the site unless instructed otherwise. Once the checks have been completed, the HGVs would leave the site to continue on their journey.

Covid-19 readiness

To limit risks from Covid-19, there would be hot and cold running water, hand cleaning facilities and provision of drinking water. The site has been designed taking social distancing into consideration, and the latest Welsh Government guidelines on Covid-19 would be followed in all circumstances.

Traffic flow and access

Directing vehicles to the border control post

The site is located close to the Strategic Road Network and the Port of Holyhead and the site would be directly accessible from the A55. Signage would be in place to direct drivers to site from the Port. In the event of any closures of the A55, the A5 would be used to access the site.

Prominent road signage

There would be prominent bilingual road signage that directs HGV drivers to the border control post. There would also be signs outside the site entrance to advise hauliers about the use of site facilities and providing site contact details.

Entry and exit points at the facility

There would be one point of access and egress to the site. HGVs would be separated by the site design, whereby HGVs arriving would be directed into dedicated holding lanes and HGVs egressing would be directed out via the existing site egress.

Staff would access and egress the site via the existing site access / egress point but would be directed to a dedicated staff car park.

Measures would be implemented to discourage drivers from exiting the site and using the highway towards Trearddur Bay Country Park.

Access & vehicle movement plan

Environment and landscaping

As part of developing site-specific proposals for the border control post, environmental assessments continue to be carried out and relevant bodies, including Cadw, Natural Resources Wales and relevant officers within the Local Planning Authority, continue to be engaged about the environmental assessment and design of the site.

A landscape strategy would be developed at the site which would provide measures to minimise the potential for adverse environmental effects.

As part of the SDO process, an environmental report has been produced. This assessment takes into consideration air quality, cultural heritage, landscape and visual effects, biodiversity, road drainage and water, and noise. The report also considers geology and soils, material assets and waste, population and health, climate, and cumulative effects. A Habitats Regulations Assessment (HRA) has also been produced. Please see Planning Documents section on this webpage to access these reports.


Potential scheme impacts on biodiversity have been assessed through a number of ecological studies. The ecological studies undertaken include an analysis of any habitats on the site and assessment of the likelihood of protected species and important habitats. Where impacts to ecology are identified, appropriate mitigation would be implemented to minimise adverse effects on local biodiversity. In addition, biodiversity enhancements would be incorporated into the scheme.

Frequently asked questions

What is the role of the Border Control Post?

The site would be used as a location to inspect goods arriving into the UK via the Port of Holyhead. The plans include parking areas for HGVs and other vehicles as well as security measures and facilities to enable the checking of vehicles entering and exiting the site. There would also be office buildings, staff and driver welfare amenities. See here for background information on the Border Control Post.

Why this location?

The site is close to the Port of Holyhead and is in close proximity to the A55, a key HGV route for accessing mainland Wales from Anglesey. Additionally, the Parc Cybi site is already designated for commercial development by Isle of Anglesey County Council.

Can the size of the proposed BCP change?

The Special Development Order (SDO) application proposes establishing a ‘consenting envelope’. This sets a maximum limit for certain aspects of the development such as the height of the building and noise, with an expectation that the constructed scheme will be significantly within these limits. This approach has been adopted to enable the assessment of the scheme through the planning process, while allowing some flexibility to adapt to requests by third parties during the site designation process (the formal approval of the BCP being appropriate for the inspections required).

What is the construction timeline, and when would the site be fully operational?

The construction phase is due to begin in summer 2022 and is due to be completed in March 2023, with the site being fully operational in April 2023.

How would impacts be managed during construction?

There would be activity on site throughout the construction phase – expected to be between the summer 2022-March 2023. To manage the impact of this on local residents and ecologies there would be limitations on daily HGV movements, work would take place within standard construction hours and would follow best practice to limit disturbance of lighting and noise. Existing ecological habitats would be protected, and reinforcement and enhancement activities to encourage biodiversity would occur as outlined in the Environmental Management Plan. All work would be contained within the site boundaries.

What facilities are available for HGVs?

Temporary rest and sanitation facilities are currently available for hauliers at Plot 9, Parc Cybi. 

Until construction begins, Plot 9, Parc Cybi will continue to be used as a HGV parking facility, Provision of future parking facilities is under review – Welsh Government has completed initial surveys to gather traffic data to determine current and future use.

How busy would the BCP be once operational?

The site is currently used as a lorry park and has a hardstanding area with capacity for 129 HGVs. The proposed future use of the site would be significantly less intensive.

Only a proportion of HGVs arriving at the Port of Holyhead would need to attend the BCP facility. The estimated number is between 25 and 30 vehicles per day. The site would have capacity to manage up to 40 HGVs at any one time, including holding lanes on site to keep traffic away from the local road network. Approximately 40-50 staff are expected on site at any one time with 75 on site staff parking spaces currently planned.

How many staff are expected on site?

Approximately 40-50 staff are expected on site at any one time, including approximately 10 marshals required to safely manage vehicles and pedestrians within the facility.

How would traffic be managed?

Site access would be from Parc Cybi via the Parc Cybi / Lon Trefignath roundabout. Checked vehicles would travel from the Port of Holyhead on the A55 before exiting at junction 2 onto the A5153 before turning onto Parc Cybi. Most staff are expected to use the same route, some may access the site from the west.

Historical ferry movement data has been used to model the scenario for vehicles arriving and departing from the BCP. The busiest time period would be between 17:00 and 18:00 when around 25-30 light vehicles and one HGV would exit the site. The capacity of the BCP and the external highway network is considered sufficient to cater for these expected movements.

As part of the traffic management strategy, Welsh Government would ensure that HGVs leaving the site would not be permitted to turn right into Lon Towyn Capel towards Trearddur and other local villages and that suitable signage would support this intention.

Staff working on-site would work different shift patterns depending on their role, shift changeover periods would be planned to occur outside of the traditional high peak hours, therefore minimising the traffic impact on the surrounding highway network.

Traffic congestion on the local road would be mitigated in the design of the BCP. HGVs would not be queuing to enter the site but held in lanes on site where they are security and safety checked before moving forward for inspection.

The on-site capacity for HGVs exceeds the number of HGVs that would be anticipated at peak times, allowing space on site for overspill vehicles.

The arrival lane at the BCP entrance, before the security gate, would enable each vehicle to be stopped briefly to ensure that it is required to visit the site.

The entire length of the route from the A55 to the BCP is currently subject to a no waiting order which is denoted by the existing double yellow lines. The enforcement of this order will continue to be applied by Isle of Anglesey County Council.

What measures would be introduced to reduce noise once the site is operational?

Multiple mitigation measures would be put in place to reduce the impact of noise on local residents, heritage, landscape and local ecology.

The site layout would be optimised to ensure that noisy site activities are screened by the new buildings and face away from the residential area, with activity mainly facing the road and business park.

A noise barrier (of provisional height 5m and length 240m) would be positioned alongside the access road. The position intended to fully screen the lanes from the south-west and south-east. The height and positioning could be subject to modification as the detailed design of the scheme is undertaken to ensure the required amount of noise reduction is provided.

HGVs that access the site would not pass by residential properties and there would be a single point of entry and exit for day to day use. A secondary emergency access is provided to be used only in special cases or circumstances such as fire/accident.

Drivers of all HGVs attending the site would be instructed to turn off their engines whilst they are parked or being inspected, this would include any engines used for cooling refrigerated trailers.

Up to 18 refrigerated trailers requiring assistance to keep their cargo cold would be able to hook-up to an electrical supply, allowing the engine to be turned off and noise to be limited.

Idling in the lanes and temporary inspection zones would be limited to no more than five minutes per vehicle.

What measures would be introduced to reduce light pollution from the BCP at night?

The site is within a partially developed area of Parc Cybi, and the spine road is already partially lit. Nevertheless, lighting measures have been incorporated into the scheme design and have been set to ensure that lighting is directional, hooded and as low in height as is practicable – light spill will be contained to the Developable Area +1m only. Dark corridors around the perimeter of the site will be maintained.

What measures would be introduced to improve the visuals of the area?

Minimising the impact of buildings on adjacent sites to the residential area to the south west was a key consideration in determining the placement and height of the buildings. Buildings and hardstanding would be contained to the land identified as the “Developable Area”. Within this area building heights would be restricted.

A minimum of 10m landscape buffer of native mixed tree species would be planted between the existing bund of trees and the developable area to screen the development from West-South-West views of the site from those living in nearby residential properties. Towards to eastern part of the site the landscape buffer would be in two sections, one south of the main access road and another section parallel to the existing bund with trees. In total both elements combined, at any single point, would provide a minimum 10m landscape buffer. Maintenance and management of this landscape buffer will happen for the lifetime of the BCP, to include replacement of any failed planting.

A Landscape Visual Appraisal included an Environmental Colour Assessment which proposes a colour palette for buildings and structures to ensure they sit within the landscape in an appropriate fashion.

Would the BCP create local jobs?

As the scheme is to be a permanent development, long-term employment opportunities would be generated.

During construction, jobs will peak at around 160 operatives, mainly sub-contractors to Kier the construction contractor. A framework agreement with Kier is in place which guarantees that Kier will create ten new jobs (five apprentices and five previously unemployed) and will host 18 work placements.

Once the facility is operational, approximately 40-50 employees per shift with three shifts over each 24-hour period would be expected. These roles include; security, cleaning, marshals, stevedores, Local Authority staff undertaking document checks and inspections and Animal Plant Health Agency inspectors, as-well as specialists in environmental health, vets and inspectors.

What other benefits would the BCP bring to the local area?

The BCP supports the long-term viability of Holyhead Port and helps safeguard the benefits the Port brings to the local area. Establishing a BCP at Holyhead is of national and local significance to the region, Wales and the UK.

The BCP will create jobs, both during construction phase and during its operation.

During construction phase 40% of the subcontracted spend during construction phase will be with North Wales small-to-medium-sized enterprises, and £10million will be procured from existing North Wales supply chains.

Would there be any hazardous materials on site?

A plan will be developed by the appointed operator which will explain how the site would be managed and operated safely, including in relation to any hazardous materials.

Why was the Special Development Order consultation period 21 days?

There is no statutory requirement to consult before making a special development order (SDO). The Welsh Ministers have the power to do things which are conducive or incidental to their functions by virtue of the common law executive functions transferred to them via section 58A of the Government of Wales Act 2006.  This includes the power to carry out consultation.

This consultation departs from the Welsh Government policy of allowing a 12 week period for consultation. The consultation ran for a period of 21 days from 24 March 2021 until 13 April 2021. The reasons for this departure are to allow for early engagement with stakeholders and take account of the requirements for checks as set out under the UK Border Operating Model.
