“I found Charles Tellerman to be extremely knowledgeable, thorough and professional. As importantly I found his hands on approach and his attention to detail essential in deciding whether to proceed with my purchases of short leases over the last ten years.”
– Mike Penn, Mansfield Street, Marylebone W1

We value and negotiate lease extensions anywhere in central London, but we specialise in the more complex valuation issues on the Great Estates
"I have used Charles on a number of occasions and have always received a most efficient service but more importantly a terrifically effective outcome well ahead of my expectations. I have no hesitation in recommending him most highly.” Alasdair Locke, Lower Sloane Street SW1
“Charles Tellerman carried out a valuation for me for a lease extension on my flat in Westminster. I found Charles to be extremely professional and courteous. He was always quick to respond to any calls or queries and he put together a very thorough and clear report, demonstrating his knowledge, experience and dedication to delivering a high quality service to his clients. He then recommended and worked closely with a solicitor to achieve a very successful outcome. I am grateful to Charles for his support and would not hesitate to recommend him to others seeking a lease extension.” Lucy Bennett, Causton Street SW1
“I decided to hire Charles after interviewing a number of surveyors. I was immediately impressed by his no nonsense approach and total command of the law and its application to the negotiation of my lease extension. His extensive experience with Grosvenor was evident throughout. Charles accepted a success based fee structure which I viewed as superior in alligning interests. He was highly competent, efficient, and an aggressive advocate for my interests until successful conclusion. I recommend him without reservation.” KAM, Eaton Square, Belgravia SW1
“Charles Tellerman gave me excellent advice in this niche sector. He is very efficient and gives excellent service. Money well spent.” Yousuf Bux, Hallam Street, Marylebone W1
“I contacted Charles Tellerman of Tellerman & Co to negotiate my lease extension, having been recommended by a neighbour. I had been disappointed by a larger firm specializing in lease extensions: they were slow to respond to my queries and had suggested an offer price higher than I thought reasonable. Charles Tellerman replied to my enquiry immediately, and he prepared a detailed valuation report with far more evidence than the larger firm. With his in-depth knowledge of my local area he successfully negotiated a final price considerably lower than even the lowest range indicated by the larger firm. Although the larger firm talked about "economies of scale" this was a false economy. Charles Tellerman was able to consider my particular case individually and everything moved fast as we did not need to wait for other flats in a consortium. My lease extension was successfully completed and Charles Tellerman was excellent from start to finish.” Edward Benson, Burwood Place W2
“I have used Charles Tellerman on two separate occasions for lease extensions. In both cases the relevant freeholder was institutional and considered difficult to deal with and it was clear from the start that I would need professional advice. On both occasions the final price Charles agreed with the freeholders valuers was the price he had advised as being the likely premium. His understanding of the Lease Reform Act is forensic and his knowledge of the local (South Kensington) property market is huge. He is also, it would appear, a very tough negotiator. Although not cheap, Charles Tellerman's overall service package from taking on a valuation on behalf of a client and then negotiating with the freeholder's valuer is excellent and I would thoroughly recommend his services for anyone embarking on lease extension, especially when the relevant freeholders are institutional bodies.” Henry Buckmaster, Cranley Gardens, South Kensington SW7
