Our business is the provision and maintenance of aids to navigation. Whether your requirement is for a rental buoy to mark an obstruction for a short or long-term period, upkeep of a varied mix of aids to navigation, condition survey and report on assets or redesign of a lighting system, Trinity House is your experienced partner of choice.

After consultation to better understand your needs and with the option of a site survey, our experts will deliver a cost-effective solution for your aid to navigation systems. A dedicated account manager will manage your project from conception to commissioning and acceptance through to commencement of our proposed life-cycle maintenance plan. We believe in carrying out the right maintenance at the right time, be it predictive, condition-based or reliability centred to extend the working life of your asset and reduce any downtime.

We are happy to maintain your own aids to navigation or provide a total turnkey operation that includes both provision and maintenance, providing safe and reliable operation of your aids to navigation ensuring compliance with statutory obligations for availability. Trinity House provides on-station cleaning, examination, maintenance and exchange plus shore-based repair, refurbishment and replacement. We take a flexible approach based on your requirements and our proposed life-cycle maintenance plan will deliver excellent value for money.

Whether you need one-off support or a service level agreement for examination and maintenance for your buoys, beacons and lights, Trinity House will ensure that your assets continue to function as specified.
