Expert Witness FAQs for Seven Sisters

We provide expert evidence for building defect disputes, party wall disputes, construction disputes, professional negligence claims and dilapidations disputes in Seven Sisters and across London.
Are your expert reports court-compliant?
Yes. Our expert reports are prepared in accordance with CPR Part 35 and the RICS practice statement for surveyors acting as expert witnesses. We have experience of giving oral evidence in court and at tribunal.
Can you provide a single joint expert for a dispute in Seven Sisters?
Yes. Where parties agree or the court directs, we can act as single joint expert. We maintain strict impartiality in all expert witness instructions.
How long does an expert witness report take for a Seven Sisters property?
Timescales depend on the complexity of the case. For straightforward building defect disputes in Seven Sisters, we can typically deliver a report within three to four weeks of inspection.
How does your knowledge of Seven Sisters building defects help your expert opinion?
Properties in Seven Sisters are prone to damp in Victorian solid-wall terraces, structural cracking in post-war social housing on London clay, defective flat roofs on 1960s–70s estate blocks. Our familiarity with these local defect patterns means we can distinguish between pre-existing conditions and defects caused by a specific party's actions, which is often central to the case.
Does the conservation area context in Seven Sisters affect expert evidence?
Seven Sisters is within Haringey; the council has conservation area designations at Noel Park and applies Article 4 directions in residential areas; town centre regeneration is ongoing. Conservation area and listed building requirements affect what works were permissible and whether a contractor or professional complied with their obligations. Our expert reports address these planning constraints directly.
Is expert evidence proportionate for a smaller Seven Sisters claim?
Sometimes not - and we say so at scoping. For modest sums, a pre-action technical review or SJE appointment usually answers the question at a fraction of full party-expert cost. Spending the claim's value on proving it is not advice we give.
How do you handle conflicts of interest on local instructions?
By checking first and disclosing everything: buildings, parties, contractors and our own group relationships are screened before acceptance. In a market as interconnected as Seven Sisters', the expert who skips that check is a liability to their own client.
