Why Accreditation Matters

An Accredited, Registered & Pre-Approved Contractor

For organisations procuring building works across East London and London, accreditation is the clearest proof that a contractor is safe, competent and compliant. RS Construction & Property Services Ltd holds and maintains the construction industry’s principal accreditations — including CHAS, Constructionline, SafeContractor and SSIP — so housing providers, local authorities, schools and commercial clients can appoint us as a pre-qualified, approved contractor without auditing our credentials from scratch.

Our Constructionline and CHAS registrations, SSIP-aligned health and safety assessment, and ISO 9001, 14001 and 45001 certified management systems mean we are routinely accepted onto approved-contractor lists and procurement frameworks. Combined with Gas Safe registration, NICEIC electrical certification and Cyber Essentials, this gives clients a single, fully accredited principal contractor for compliant project delivery across the capital.
