Rushworth Inspection Services and Auditing

Rushworth Inspection Services and Auditing (RISA) is the United Kingdom's foremost independent and impartial inspection and auditing body dedicated to the fenestration and construction industries. Established as a specialist subsidiary of the Glass and Glazing Federation (GGF) Group and headquartered at Newspaper House, 40 Rushworth Street, London SE1 0RB, RISA provides a comprehensive range of on-site inspection, auditing, and compliance verification services. The organisation serves a broad client base spanning private homeowners, glazing installers and contractors, housing developers and social landlords, and the legal and insurance sectors, delivering expert and impartial scrutiny of window, door, and rooflight installations throughout England, Scotland, Wales, and Northern Ireland.

RISA holds UKAS accreditation as a Type A Inspection Body (Accreditation No. 9888) under ISO/IEC 17020:2012, the internationally recognised standard governing the competence and impartiality of inspection bodies. This accreditation specifically covers the inspection of the installation of replacement windows, doors, and rooflights, incorporating the relevant requirements of the Building Regulations and the FENSA Competent Person Scheme requirements. Of particular significance, RISA is the sole approved provider of field inspection services for FENSA Ltd — a Government-endorsed, UKAS-accredited Competent Person Scheme Operator for the replacement window and door industry in England and Wales — a designation that underscores the organisation's unrivalled regulatory standing in the sector.

The core inspection and auditing services offered by RISA encompass domestic window and door installation inspections, building regulation compliance inspections, and technical assessments carried out in accordance with British Standard BS 8213-4 (Windows and Doors — Code of Practice for the Survey and Installation of Windows and External Doorsets). Assessors evaluate quality of workmanship, correct use of approved ancillary components such as flashings and sealants, compliance with thermal and acoustic performance specifications, and adherence to relevant planning and conservation area conditions. Inspection reports are detailed, evidence-based, and produced in real time using bespoke mobile assessment tools that transmit findings directly to RISA's administration team and to clients, enabling efficient turnaround and immediate access to results.

RISA also offers a specialised pulse-testing service for air permeability assessment of dwellings before and after window or door installation. This service — available to both installers and homeowners — provides certified proof that the airtightness of a property has not been adversely affected by a replacement glazing installation. Upon a satisfactory result, clients receive a formal test certificate recognised by Local Authority Building Control, competent person scheme inspectors, and conveyancing surveyors. This service has become particularly valuable following the updated Building Regulations that came into effect in June 2022, which introduced extended requirements around trickle vent installation, as pulse-test evidence can resolve specification disputes and spare installers from unnecessary and costly remedial works.

For the legal and insurance sectors, RISA provides expert witness reports and independent technical assessments for a wide range of disputes and proceedings. Services include reports for Section 75 credit card claims arising from glazing installations, court proceedings, insurance claims, and professional indemnity cases. RISA assessors are trained to produce clear, authoritative written reports meeting the requirements of civil court expert evidence, making the organisation a trusted technical partner for solicitors, loss adjusters, surveyors, and insurers handling fenestration-related litigation. The team also assists homeowners in pursuing remediation from installers where work falls below the required standard, and supports installers in defending complaints and workmanship disputes with independent evidence.

RISA's field team covers the entirety of the United Kingdom, comprising inspectors, auditors, and inspection managers who are recruited directly from the industries they assess. Collectively, the team brings more than 400 years of combined professional experience in glazing, fenestration, and building regulation compliance. Because assessors come from the trade itself, they carry practical, hands-on knowledge of correct installation methods, product specifications, and common failure modes that purely desk-based auditors cannot replicate. Field staff are equipped with purpose-built scheduling and mobile reporting tools that enable real-time data capture and efficient nationwide deployment, while an experienced administration team based in the London office coordinates all appointments to fit around clients' and occupants' schedules.

As a constituent of the wider GGF Group — the principal trade body representing the UK's glazing and fenestration industries — and a member of the National Home Improvement Council (NHIC), RISA has direct access to the full technical resources, policy expertise, and industry knowledge of the Glass and Glazing Federation. This affiliation enables the organisation to maintain inspection methodologies that are current with evolving Building Regulations, British Standards, and industry best practice. Whether acting for a private homeowner seeking independent reassurance about a recent installation, a social housing provider commissioning a compliance audit across a development, or a legal team requiring an authoritative technical opinion, RISA delivers a rigorous, impartial, and professionally supported inspection service backed by the highest industry accreditations available in the UK fenestration sector.
