SI Property Consultants Ltd

Since 2002, we have operated as a dynamic and progressive Building Surveying firm with a singular focus: providing unambiguous, professional advice that stands up to the highest scrutiny. Whether you are a homeowner planning an extension, a solicitor seeking an expert witness, or a commercial landlord managing a portfolio, we bring over two decades of RICS-regulated expertise to your project.

Expert Evidence Trusted by the Courts

What sets us apart is the weight our evidence carries. We are frequently called upon to provide independent advice and formal expert reports for court proceedings. Our work has been specifically commended by the judiciary for its clarity and technical depth:

"I unambiguously and firmly prefer the evidence of Si Property Consultants... it is entirely consistent." — Judge Saggerson

"I was particularly impressed by evidence when asked in cross-examination about thermal efficiency." — Judge Monty KC

Over 1,500 Party Wall and Boundary Matters Resolved

Navigating the Party Wall etc. Act 1996 can be a minefield for both building owners and neighbours. We have acted in over 1,500 Party Wall and boundary dispute matters, ranging from residential extensions to high-profile cases for Members of Parliament and Cabinet Ministers.

We don't just tick boxes; we advise on construction schemes and their likely impact on neighbouring structures to prevent disputes before they arise. If a dispute has already begun, we provide the technical evidence needed to reach a resolution, as seen in our work on landmark cases like Brown v Shepherd Bush Housing Assoc and Raja v Charles.
