Frequently Asked Questions — Cellnex Phone Mast Leases

Cellnex acquired On Tower UK Ltd (which was previously known as Arqiva Services' mobile infrastructure division) as part of its expansion into the UK market. Arqiva sold its mobile mast business in 2020. If you have a lease originally with Arqiva for mobile masts, your current landlord is likely Cellnex or On Tower (part of Cellnex). Arqiva itself now focuses solely on broadcast infrastructure.
Like all operators and infrastructure companies, Cellnex can seek rent reductions under the Electronic Communications Code's 'no-scheme' valuation model. Specialist independent advice is essential to challenge these proposals and protect your rental income.
Not necessarily under the current ECC framework, but this can be an important negotiating consideration. The sharing of infrastructure by multiple operators on your land may support arguments for higher consideration. We assess your specific situation and advise on what arguments are available.
Contact us immediately. Statutory notices under the Electronic Communications Code carry specific timeframes, and missing a deadline can damage your legal position. We offer a free initial review of all lease documents and notices.
On Tower UK Ltd is a subsidiary within the Cellnex group. It was formerly the mobile mast infrastructure division of Arqiva, which was sold in 2020. For practical and legal purposes, On Tower operates within the Cellnex corporate structure.
Cellnex mast rents vary by location, site type, and the number of operators using the site. As a neutral host infrastructure company, Cellnex may host multiple mobile networks on your land. We have comparable evidence from Cellnex and On Tower negotiations and can advise on what your site should be achieving.
Cellnex (or On Tower UK Ltd) will contact you about renewing or replacing your lease, typically proposing new Code terms. Given their commercial experience and the complexity of the ECC framework, independent specialist advice is essential before you respond to anything.
Do not engage with Cellnex or On Tower before taking specialist advice. Call us on 01691 791543 for a free initial consultation. We will review your documentation and advise on the best approach before any dialogue with the operator.
The ECC applies to Cellnex and On Tower in the same way as mobile network operators. The 'no-scheme' valuation approach can produce lower rents than pre-2017 market assessments. We advise on your specific position under both the ECC and any applicable LTA 1954 protections.
Cellnex leases often include broad multi-operator hosting provisions, extensive upgrade and access rights, and break clauses in the operator's favour. As a neutral host, Cellnex may seek to host multiple operators on your site — understanding the implications for your rent and lease terms is important. We review all proposed terms and advise accordingly.
