Maple House Case: Summary & Key Learnings

Case Name: Cornerstone Telecommunications Infrastructure Limited v London & Quadrant Housing Trust

Citation: [2020] UKUT 282 (LC)

Date: 14 October 2020

Key Issues:

This case centred around the terms of a Code agreement for new telecommunications apparatus on the rooftop of Maple House, a building of offices and flats in Peckham, South London, owned by London & Quadrant Housing Trust. The landowner accepted that an agreement should be imposed. The primary issues were the operator’s rights to install, upgrade and share equipment, the rent (known as consideration) and compensation.

Tribunal Decision:

The Tribunal was tasked with determining appropriate terms for a new ten-year agreement, including the rent and the operator’s upgrading and sharing rights.

Key Findings:

Rent Determination:

The Tribunal assessed the rent on the Code’s no-network assumption, using evidence of comparable agreements for residential rooftop sites.

The annual consideration was set at £5,000, reflecting a nominal site value plus allowances for the landowner’s building maintenance and insurance, the burden of managing access, and the operator’s sharing and upgrading rights. The Tribunal said it would not expect rooftop sites on other residential buildings to be worth much more or less than this.

Lease Terms:

Most terms were agreed between the parties, including a ten-year term which the operator can end on six months’ notice. The Tribunal rejected the landowner’s request for an equipment cap, allowed upgrading without limit, and allowed sharing with up to two operators, with any further sharing only within the Code’s paragraph 17 conditions.

Compensation:

The only compensation awarded was £3,068 for the landowner’s reasonable legal expenses in advising on and completing the agreement.

Implications for Landlords:

Fair Rent Established:

The Tribunal’s decision provides a benchmark for setting rent levels. However, landlords might feel that the rent, while fair under the New Code, does not always reflect the property’s potential revenue. Under the New Code, there is no statutory cap on rent, but the no-network assumption in paragraph 24 tends to produce rents significantly lower than the telecoms market used to pay. The annual rent for rooftop and standalone (greenfield) sites can vary considerably.  To ensure that you are receiving the correct rent it is crucial to instruct a specialist agent to assist in negotiating and determining the highest possible rent for your specific site. 

Clear Lease Terms:

The Tribunal’s ruling offers clear guidelines on lease terms, which can aid landlords in future negotiations. However, it also means that landlords have less room to negotiate for higher rents, potentially feeling constrained by the precedent set in these rulings.

Precedent for Compensation:

The case confirms that, where an agreement is imposed, landlords are entitled to compensation for the reasonable legal expenses they actually incur, rather than a conventional contribution, as well as consideration for the use of their property.

Summary:

The Maple House case sets a critical precedent for telecommunications leases in the UK. While it provides clear guidelines and ensures fair compensation for landlords, it also imposes obligations that might limit flexibility. Landlords might feel that the established rents do not fully reflect the market value of their properties. This case highlights the need for balanced negotiations and careful market consideration in lease agreements, with an understanding that the Tribunal’s decisions can set a restrictive benchmark for rents under the New Code.
