Our landlords.

To achieve mobile connectivity in rural and urban areas, we need to place the right infrastructure in the right place. Our landlords are key in making this happen by allowing us to place our radio mobile apparatus on their land or rooftops. This has enabled us to acquire and manage over 20,000 sites that provide mobile connectivity around the UK.

Our landlords

“Working towards improving our digital economy is a key driver for Cornerstone and to help deliver this, we are committed to becoming a trusted partner of all our landlords and will make every effort to consider them in everything we do.”

Belinda Fawcett

Our commitment to enhance and deliver mobile services is practised through building our relationships with our landlords. Whether it’s for a new site install, equipment upgrades or general site maintenance, we engage with our landlords continuously.

Our landlord pledge.

Our Landlord Pledge introduced in 2016 is a promise to our landlords to always work and effectively communicate with them. We are committed to practising the landlord pledge and always welcome feedback to ensure we provide our landlords with best-in-class service.
