Notes to editors

Derwent London plc

Derwent London plc owns 70 buildings in a commercial real estate portfolio predominantly in central London valued at £5.36 billion as at 31 December 2022, making it the largest London-focused real estate investment trust (REIT).

Our experienced team has a long track record of creating value throughout the property cycle by regenerating our buildings via development or refurbishment, effective asset management and capital recycling.

We typically acquire central London properties off-market with low capital values and modest rents in improving locations, most of which are either in the West End or the Tech Belt. We capitalise on the unique qualities of each of our properties - taking a fresh approach to the regeneration of every building with a focus on anticipating tenant requirements and an emphasis on design.

Reflecting and supporting our long-term success, the business has a strong balance sheet with modest leverage, a robust income stream and flexible financing.

As part of our commitment to lead the industry in mitigating climate change, Derwent London has committed to becoming a net zero carbon business by 2030, publishing its pathway to achieving this goal in July 2020. In 2019 the Group became the first UK REIT to sign a Revolving Credit Facility with a 'green' tranche. At the same time, we also launched our Green Finance Framework and signed the Better Buildings Partnership's climate change commitment. The Group is a member of the 'RE100' which recognises Derwent London as an influential company, committed to 100% renewable power by purchasing renewable energy, a key step in becoming a net zero carbon business. Derwent London is one of the property companies worldwide to have science-based carbon targets validated by the Science Based Targets initiative (SBTi).

Landmark buildings in our 5.5 million sq ft portfolio include 1 Soho Place W1, 80 Charlotte Street W1, Brunel Building W2, White Collar Factory EC1, Angel Building EC1, 1-2 Stephen Street W1, Horseferry House SW1 and Tea Building E1.

In January 2022 we were proud to announce that we had achieved the National Equality Standard - the UK's highest benchmark for equality, diversity and inclusion. In October 2022, 80 Charlotte Street won the BCO's Best National Commercial Workplace award 2022. In October 2021, the Group won EG's UK Company of the Year award and in January 2022 came top of the Property Sector and 38th position overall in Management Today's Britain's Most Admired Companies awards 2021. In 2013 the Company launched a voluntary Community Fund which has to date supported over 150 community projects in the West End and the Tech Belt.

The Company's share capital is comprised of a single class of 5p ordinary shares (ISIN: GB0002652740).

The Company is a public limited company, which is listed on the London Stock Exchange and incorporated and domiciled in the UK. The address of its registered office is 25 Savile Row, London, W1S 2ER.
