What Szerelmey does

Szerelmey is a UK-based heritage restoration and new build specialist contractor founded in 1855, headquartered at 369 Kennington Lane, Vauxhall, London. The company operates through a group of eight wholly-owned UK private limited entities (including Szerelmey Limited, Szerelmey Restoration Limited, Szerelmey (GB) Limited, and Szerelmey (UK) Holdings Limited) and delivers four core service lines: specialist restoration (cleaning, repair, remodelling, retained facades), new build hard landscaping (facades, full wall build ups, interiors, hardscape), faience and terracotta design-supply-install, and an in-house design and consultation service. Its technical capabilities include DOFF cleaning, nebulous cleaning, stone repair and replacement, retained facade techniques (facade stretching, adaptive reuse, dismantling and reinstating), and sustainable stone sourcing through its Ethical Stone Register Verification status. The business model is project-based, operating as either Principal Contractor or Specialist Subcontractor, with individual project values ranging from £80K to £6.7M+, secured through competitive tenders and direct client engagement.

The company serves enterprise and institutional clients across heritage, cultural, commercial, banking, education, royal/government, residential, and transport sectors, with named projects including Battersea Power Station, National Gallery, Royal Opera House, Natural History Museum, Windsor Castle, Rothschild Bank New Court HQ, 100 Bishopsgate, Stanhope's Woolgate Exchange, and Almacantar's Marble Arch development. Revenue is generated through professional services contracts (construction project services and design/consultation) with no standardised pricing; engagement is tender-based. Marketing is conducted primarily through project portfolio showcasing, industry awards (RIBA, Natural Stone Awards, Building Awards), and sustainability credentials, with no direct sales force or digital channel-driven growth model. The company holds ISO 9001, ISO 14001, ISO 45001, Cyber Essentials, CHAS, Constructionline, and Living Wage Foundation certifications, and was the first contractor to join the Ethical Stone Register and first to achieve Verification level, with a Circularity in Practice pledge signed in March 2026.
