OPS Chartered Surveyors is a friendly, professional and multi-disciplinary architectural design and property consultancy, helping homeowners and families unlock the full potential of their homes.

We help clients with architectural design, home extensions, loft conversions, garage conversions and planning applications, to create more space and improve the way their homes work for everyday family life. Whether you are planning a larger kitchen, extra bedroom, home office or full property refurbishment, we are here to guide you through the process from start to finish.

We also help with Party Wall matters, Planning Enforcement, Building Regulations and general property advice, giving clear and practical guidance without confusing technical jargon.

We understand that building works and council applications can often feel stressful or overwhelming, especially for busy families, so we pride ourselves on providing a personal, approachable and honest service tailored to each client’s individual needs.

Much of our work comes through recommendations and repeat clients, and we are committed to helping homeowners achieve practical, well-designed spaces while protecting and enhancing the value of their properties.

Sammy was extremely knowledgeable and guided us through the whole process. We went for two separate planning applications and both were approved with no issues both times. Having an architect that is also a structural engineer is extremely useful too and speeds up the whole process! Definitely recommend.

Sammy is a very knowledgeable and experienced surveyor. The quality of his work was outstanding. His responses were quick and practical. My home is in a conservation area, and his advice is particularly tailored and relevant. Therefore, I highly recommend Sammy for his excellent service.

We have engaged OPS for a level 3 survey report in June 2025. The survey was arranged in a few days. Sammy gave us a quick update by phone a few hours after completing the survey to inform us of his key findings regarding the property. The full survey report was out one week after the survey and Sammy provided a very detailed explanation of the report on the phone, with clear advice on which areas we need to pay attention for clarification with the lawyer and landlord, and listed out the items that we may claim compensation from the landlord when we proceed with the purchase. We had many subsequent calls with Sammy on advice regarding renovations and Sammy provided very helpful advice, and also referred different experts for services like asbestos examination, boiler installation, submitting application for building control etc. In our opinion, Sammy has a very high professional standard and also offers friendly advice for his clients, highly recommended!

I recently engaged OPS for advisory services regarding the extension project for my workshop. Sammy was professional, reliable, and highly knowledgeable throughout the process. We were very pleased with the service he provided and greatly appreciated his attention to detail. He took the time to patiently explain the reasoning behind what could and could not be done, helping us understand the options available for our ideas. I would highly recommend OPS, and Sammy is undoubtedly a trustworthy, responsive and dependable surveyor.

As a landlord and property owner, I have worked with many professionals over the years, and Sammy is one of the few I would confidently recommend without hesitation. He has assisted me with multiple projects, including HMO-related work and residential design projects. His technical knowledge, attention to detail and practical approach have been outstanding throughout. What I value most is his reliability. Whenever an issue arises, Sammy responds quickly, explains the options clearly and helps find a sensible solution. He understands not only the technical requirements but also the commercial realities that property owners face. His professionalism, honesty and commitment to client service make him a pleasure to work with. I genuinely feel that he cares about achieving the best outcome for his clients rather than simply completing a job. I look forward to working with him on future projects and would highly recommend OPS Chartered Surveyors to any homeowner, landlord or property investor.

Excellent experience from start to finish! The service was professional. I would highly recommend this business to anyone looking for a reliable and high-quality experience. I will definitely be returning in the future!

We recently worked with OPS on our HMO licence application. He visited the property the day after our initial enquiry and submitted the application within two weeks. Thanks to his dedicated work and expertise, our licence was successfully granted just one month later. We really appreciated his efficiency, professionalism, and support throughout the process, and would highly recommend his services.

I have used OPS for many years now and recommended them, they are very professional, keeping you up-to-date with any changes they are there to work with you with your design. I would recommend using this company.

Sammy is a highly professional, knowledgeable, friendly, and responsive surveyor. He supported me with the planning application and Building Control submissions for my porch, garage conversion, and new windows. Thanks to his diligent work, the entire process was smooth and well‑managed. He was proactive throughout the Building Control stage, providing practical solutions to address the inspector’s comments - even some of these comments were minor or not entirely aligned with the practical realities on site. He also liaised directly with the Building Control team and other professionals to discuss technical issues and agree on effective remedial actions for my builder to implement. Whenever I had questions about my property, Sammy consistently responded within one or two hours. His responsiveness has been invaluable. In short, if anyone asks me for a recommendation for surveying, planning applications, or Building Control consultation, I would not hesitate to recommend Sammy.

I recently worked with OPS on my home extension project, and the experience was outstanding from start to finish. Sammy is detail‑oriented, professional, and truly responsible in every aspect of their work. They provided practical advice that was not only technically sound but also genuinely useful for making informed decisions. What I appreciated most was their communication style — they always listened to my ideas first, then offered realistic and constructive counter‑suggestions based on their expertise. OPS is highly familiar with local regulations and council requirements, which made the entire process smooth and stress‑free. My extension was completed to a standard that exceeded my expectations. I am extremely satisfied with the result, and I sincerely recommend OPS to anyone looking for reliable and professional service.
