Who we've worked with

Clients

See what they have to say...

“From RX London, Frankie and Dan, joined the team to help conclude the leasing programme on our Ropemaker development. They did so, having given balanced but honest feedback as part of the pitch process. We set about fine-tuning our approach, both in terms of emphasis and collateral. We were delighted to see them concluding a letting of 65,000 sq ft to Pension Insurance Corporation Plc, being all the remaining offices. A great result all round.”

James Cooksey, CEO, Old Park Lane Management

“May I take this opportunity to say that we are grateful for the high-quality advice that Charles and Paul have been giving us to date on our potential lease restructure/office relocation project and in relation to the rent review negotiations with our sub-tenants in 50 Berkeley Street. We hold Charles in high regard, and it has been very good to also benefit from Paul’s insights and wise counsel in recent months.”

Robert Farrer-Brown, General Counsel, Lazard

“Highly commended! Navigating our office relocation was not without challenge with many potential pitfalls identified by RX London through the negotiation and due diligence phases of the search. Frankie and Sophie addressed these issues head on, making the process as smooth as possible whilst protecting our position every step of the way.”

Justin Fahy, Managing Director, StructureTone

“We set RX London a tough task of finding good-quality office space in a central, highly accessible location within our budget. They ran a comprehensive, city-wide search and Stewart House was identified as an off-market opportunity which was perfectly positioned for us, as London’s growth agency, to be located in a high-profile location right by Russell Square. The acquisition was not straightforward and required a change of use. RX negotiated a great deal for us and supported us through the entire process with a service that was tailored, fast and efficient. They were responsive to changes in requirements and search parameters to help us build a case to present at multiple stakeholder levels. We couldn’t be more pleased with the outcome.”

James Morgan, London & Partners

“Frankie and Helie’s expertise were invaluable in securing our new headquarters at 20 Water Street. Their deep understanding of our needs as a rapidly growing digital bank, combined with their market knowledge, ensured we found a space that not only meets our current requirements but also supports our future ambitions. The team’s ability to negotiate branded signage at the top of the building was a particular coup, reinforcing our position as a challenger in the banking sector. We couldn’t have done it without them!”.

Emily Dickens, Head of People Experience, Zopa

“We chose to work with RX London because they were more creative and presented us with more interesting ideas than the other mainstream agencies we were considering. Frankie was very proactive and supportive, she led the project and worked with us every step of the way, attending all viewings, fronting all negotiations and running all the analysis. She challenged some of our preconceptions and provided real tangible advice which was invaluable in leading the Partnership to make a unanimous decision on a preferred option. I would not hesitate to recommend her.”

Justin Phillips, London MD, Buro Happold

“Many thanks to the RX Team for finding us the perfect office for our needs, in a fast, friendly, and efficient way. We were grateful to find a newly refurbished office space before it went to market and for your help with the negotiations.”

Robert Brown, ICEN Risk

”An excellent result on this review which has gone down very positively internally.”

Steven Mew, Property Director, GPE

“The RX London team have enhanced our market reach; we are no longer just talking to the traditional agency market. The team have strong relationships with brokers, resulting in enquiries and offers, and a good understanding of the negotiating approach in this field. They have opened our eyes to listing our product on broker – led platforms. Subsequently this has reduced voids, driven rents and reduced incentives across our leasing transactions.”

Isabel Thomas, Head of Offices, Shaftesbury Capital PLC

“Charles, just a short note to thank you for all the assistance you have provided in securing the acquisition of land from Westminster. As you know this was a critical part of the site assembly to allow the development of Bowater House and your help was much appreciated.”

Christian Candy, Candy & Candy

“RX have a deep understanding of our investment strategy, which they demonstrated by identifying an asset off – market with a willing seller which perfectly suited our flex requirement. They have a close relationship with both GPE and Orchard Street IM, which meant they were able to help us navigate any issues as they arose during due diligence, resulting in a seamless and quick transaction. We have now completed the development to an exceptional standard, and are delighted with the levels of interest we’ve received in the space. We look forward to working with RX on future acquisitions!”

Alexa Baden – Powell, Senior Investment Manager, GPE

“We have been really impressed with Frankie and the team at RX London. They provided us with a highly personalised level of service, taking time to really understand us a business and this shone through in the options presented and the advice provided. Frankie was heavily involved through the whole process and negotiated a great deal for us exceeding our expectations. Delighted to recommend RX London and their acquisition advisory services.”

Sham Jagpal, Financial Director, Zopa

“Our decision to enlist the services of Charles Cowley at RX London is one I consider to have been one of our best. We use Charles for his lease advisory services on all our office properties in London.”

Adam Goldin, Head of UK, CC Land

“Frankie has been an invaluable partner to Beltane Asset Management for many years. What sets her apart is her understanding of occupiers as well as her deep knowledge of the London commercial market. This has been particularly evident on our One Millennium Bridge project, a 250,000 sq ft redevelopment where she led on the Alix Partners deal, securing a great result and getting it over the line within 6 weeks of agreeing terms.”

Jonathan Chenery, Beltane Asset Management

“Jordan was outstanding in delivering real value at 45 Pall Mall. His strategic thinking and hands-on approach to leasing and lease restructuring helped us secure stronger terms and drive additional upside for our investors. His market insight, deal-making instinct, and ability to navigate complex negotiations made all the difference. A top operator and a pleasure to work with.”

Paul Harris, Executive Director, JP Morgan Asset Management

“Well done all – fantastic settlement and really appreciate your efforts to get it over the line in time for our mid-year valuations / reporting.”

Isabel Turner, Asset Manager, British Land

“We have been delighted with RX London’s advice through the initial acquisition and subsequently as they have helped us move on the rental tone in the building. They are always responsive and give imaginative and well – considered advice.”

David Bell, Chief Executive, Darin Partners
