What SASSEN ENGINEERING LTD. does
SASSEN ENGINEERING LTD. is a UK private limited company operating as a residential structural engineering consultancy. The company provides chartered structural engineering services — including beam calculations, foundation design, structural surveys, load-bearing wall removal assessments, loft conversion support, subsidence evaluation, new build structural design, and Building Control liaison — to UK homeowners undertaking renovations, builders requiring project documentation, property developers, and property buyers/sellers needing structural reports for transactions. Services are delivered through direct website quote requests, phone/email consultations, and on-site visits, with engineers always visiting site before quoting.
The underlying technical capability centers on 3D CAD structural modeling used to produce design drawings and calculations, with growing integration of sustainable material alternatives (recycled steel, engineered timber, hempcrete, insulated steel). The firm operates a sales-led GTM motion built around 40+ city-specific SEO landing pages covering major UK locations from Aberdeen to Plymouth, supported by educational content marketing targeting top-of-funnel search intent. Revenue is generated on a project-based professional services model with staged payment (deposit upfront, balance on delivery), with published pricing ranging from £250–£850 for smaller surveys and £800–£2,500 for full remodel calculations, climbing higher for complex basements and bespoke builds.
The company differentiates via chartered engineer credentials (IStructE, ICE membership), professional indemnity insurance coverage, regional Building Regulations expertise across diverse UK housing stock (Georgian, Victorian, post-war, modern), and a founder-led first-person customer communication style. Note: A firmographic short description refers to the company as a precision engineering / CNC machining / custom rifle barrel manufacturer founded in 1964; however, all operational data — products, pricing, GTM, locations, website content — describes a residential structural engineering consultancy, which is treated as the operational reality for this analysis.
