What VECTOR LEAK CONSULTANTS LTD does

Vector Leak Consultants Ltd is a UK-based independent technical consultancy specializing in roof leak detection, waterproofing design review, and permanent moisture monitoring for complex roof assemblies including landscape roofs, green roofs, buried waterproofing systems, and CLT/mass timber structures. The firm was founded by Andrew Flood (Managing Director, 25+ years of roofing and leak detection experience) and is led alongside Technical Director Ben Hickman, who holds an MSt in Interdisciplinary Design from Cambridge, is an appointed court expert witness in waterproofing disputes, and served as Key Technical Author of CIRIA C817 (Blue Roofs) and contributing committee member on BS 8102:2022. Vector is headquartered at Wrest Park, Silsoe (Bedford) and serves clients across the United Kingdom.

The company's core technology rests on exclusive UK rights to two European sources: Norwegian battery-powered leak detection sensors (20+ year battery life, no mains penetration) and Dutch Electrical Field Mapping (EFT/EFM) technology from Texplor for locating membrane breaches in buried waterproofing to within approximately one metre, calibrated to SIKB 6700/67001/67002 Dutch standards. The service portfolio includes Buried Leak Location, Permanent Leak Detection & Sensor Monitoring, Waterproofing Design Review, Quality Assurance during installation, Roof Condition Surveys, Geomembrane Leak Detection, CLT Moisture Monitoring, and a flagship Complete Roof Assurance integrated platform covering the roof lifecycle from RIBA Stage 3 design review through to planned preventative maintenance. Services are sold to Tier 1 contractors, institutional developers, housing associations, asset managers, and architects, with customers including Balfour Beatty, Argent, Quintain, and McLaughlin & Harvey.

The business operates a hybrid revenue model combining subscription recurring revenue from permanent monitoring contracts (monthly billing, no minimum contract beyond the first year) with project-based professional services for investigations, design reviews, and QA inspections. Pricing is quote-based and not publicly disclosed; design review is provided free of charge for standard schemes, functioning as a top-of-funnel acquisition channel. GTM is sales-led B2B, with most engagements originating through professional networks, contractor referrals, expert witness appointments, and repeat business rather than broad digital marketing. The company is privately held and founder-owned, with no disclosed external investors or funding.

Products and services

• Buried Leak Location Non-destructive electrical field mapping service that locates membrane breaches to within approximately one metre without removing overburden. Uses Texplor EFT technology from the Netherlands, held under exclusive UK rights by Vector. Includes site inspection, electrical field survey, contour map, written report, and optional post-repair verification. Targeted at building owners, contractors, and asset managers dealing with landscape roofs, green roofs, podium decks, and buried waterproofing systems where the leak symptom and entry point are not in the same location.
• Permanent Leak Detection & Sensor Monitoring Subscription-based continuous monitoring service covering complex roof assemblies, CLT structures, green roofs, landscape podium decks, and inverted/buried waterproofing systems. Vector installs and commissions embedded sensors (exclusive UK access to Norwegian Sensor Innovation battery-powered sensors), provides automated real-time alerts on moisture change, quarterly performance reports, biannual physical inspections to BS 6229 Clause 8.2, an annual condition review, and manufacturer warranty compliance maintenance. Predictable monthly cost with no minimum contract beyond the first year. Designed for institutional asset owners, developers, and asset managers needing a continuous independent record of roof performance.

Partnerships

Two partnerships are on record, tiered core.

• TexplorcoreTechnology or IntegrationVector holds exclusive rights to use Texplor's Electrical Field Mapping (EFM/EFT) technology in the UK. Texplor is a specialist in geophysical measurement based in the Netherlands providing buried leak location technology for geomembrane verification. The partnership delivers to UK clients the highest standard of global best practice, including SIKB 6700, 67001, and 67002 (Dutch standards) which meet or exceed LGG 113 and ASTM D7953/D7002 requirements. Vector has worked closely with Texplor for years, training together and refining techniques. This technology is not available from any other UK provider.
• Norwegian Sensor InnovationcoreTechnology or IntegrationVector is the exclusive UK partner for Norwegian Sensor Innovation — providing battery-powered leak detection sensors for permanent monitoring applications. Sensors are approximately the dimensions of an ice hockey puck with ~40mm depth and battery life exceeding 20 years. Critically, sensors are battery-powered rather than mains-powered, avoiding cable runs that would create new penetration leak risks. These sensors are used in CLT and mass timber monitoring, green roofs, landscape podium decks, and inverted/buried waterproofing systems.

Scale indicators2 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Arup: Global engineering consultancy with deep UK building services and structural waterproofing capabilities. Regularly engaged by major developers and asset owners on complex roof and below-grade waterproofing — adjacent rather than direct competition to Vector.
• Stantec UK (formerly MLM Group): International engineering consultancy with a UK building consultancy practice covering building envelope, waterproofing advisory and asset management. Overlaps with Vector on waterproofing review and inspection but operates at much larger scale and broader service portfolio.
• Ramboll: Global engineering, design and consultancy company with significant UK presence, including structural waterproofing and building envelope advisory teams. Competes for the same institutional and developer clients but as one service line inside a much broader portfolio.
• WSP: Global professional services consultancy with UK building and asset management practices that overlap Vector's waterproofing and building safety work. Differs in scale, breadth of services and integrated delivery model.
• Mott MacDonald: Global engineering consultancy providing building and infrastructure services in the UK, including waterproofing and asset management advisory. Operates at significantly larger scale than Vector with a broader project portfolio.

Direct peers

• Sandberg LLP: UK construction consultancy providing independent building and structural inspection, materials testing and expert witness services. Closest UK comparable in terms of independent consultancy model serving contractors and developers on complex building envelope and structural matters.

Regional players

• Waterman Group: UK-based engineering and environmental consultancy with structural and building services capabilities. Provides overlapping technical advisory to UK commercial property clients but with a much broader service mix and limited specialist focus on buried-membrane leak location.

Emerging players

• Newton Waterproofing: UK specialist in structural waterproofing products and systems that also provides design and on-site support services. Operates in the same waterproofing value chain but combines a product manufacturer role with consultancy, unlike Vector's pure independent model.
