Ryedale Testing is a family-run building compliance specialist headquartered at Cedar Studio, 42 Town Street, Old Malton, North Yorkshire, United Kingdom. Established in 2007 and drawing on more than 35 years of combined experience in the building industry, the company delivers every service in-house without outsourcing, ensuring continuity of expertise and tighter project co-ordination from first instruction through to final sign-off. Operating nationwide across the UK, Ryedale Testing serves major volume housebuilders, tier-one main contractors, and smaller regional developers who need reliable, schedule-sensitive compliance testing on new-build and conversion projects.

The company's flagship discipline is air tightness testing, conducted for both domestic dwellings and commercial buildings in strict accordance with ATTMA (Air Tightness Testing and Measurement Association) technical standards. Ryedale Testing is an accredited ATTMA member and uses only high-quality UKAS-calibrated instruments to measure air permeability. For new domestic dwellings, the regulatory threshold under Building Regulations Part L is typically 10 m³/(h·m²) at 50 Pascals, and the team provides pre-test advice and guidance to identify and seal air leakage paths before formal testing commences, significantly reducing the risk of failures and re-tests. A two-tier service model is offered: a standard programme with a 14-day lead time and an emergency service for projects where construction programme has slipped and handover deadlines are at risk.

Acoustic testing constitutes the second major pillar of Ryedale Testing's portfolio. The company performs Pre-Completion Sound Testing to demonstrate compliance with Building Regulations Schedule 1 Part E and Approved Document E, covering both airborne and impact sound insulation of separating walls and floors in new-build residential and mixed-use schemes. All results are assessed against the minimum weighted sound reduction index values required for handover. Where project schedules allow, acoustic and air tightness visits can be co-ordinated on the same site visit, delivering programme and cost efficiencies for the site team. Broader noise assessments to address wider acoustic environment requirements are also available.

Extract fan testing is offered both as a standalone service and as an add-on to air tightness visits. Mechanical ventilation extract systems installed in kitchens, bathrooms, and utility spaces must meet minimum flow rates under Building Regulations Part F, and Ryedale Testing provides independent measured verification of installed fan performance against those benchmarks. The company also delivers Standard Assessment Procedure (SAP) calculations and Energy Performance Certificates (EPCs) for new-build homes and residential conversions. SAP is the UK government's approved methodology for rating the energy and environmental performance of dwellings, and accurate SAP outputs are a prerequisite for Building Regulations approval and, in many cases, for planning discharge. Supplementary heat loss calculations for properties with high glazing ratios are likewise offered, helping design teams demonstrate thermal compliance where standard elemental approaches are insufficient.

Ryedale Testing operates an in-house architectural services division spanning initial and detailed design, planning applications, building regulations submissions, specification writing, tendering support, and inspection of works in progress. This breadth of capability means clients can engage the company at concept stage and retain the same multidisciplinary team through construction and final compliance certification, reducing consultant hand-offs and programme risk. The integration of architectural services alongside compliance testing is a distinctive feature that sets Ryedale apart from single-discipline testing providers.

The company's client roster features some of the most prominent names in UK volume housebuilding and contracting, including Keepmoat, Wates, Tolent, Wilmott Dixon, and Barratt Homes. Published testimonials from project directors and site managers at these organisations consistently praise Ryedale Testing's commitment to meeting handover deadlines — including working through the night and developing alternative testing programmes when standard approaches are insufficient — as well as their practice of resolving compliance issues and re-tests without imposing additional charges. This client-first culture, combined with a zero-outsourcing policy, distinguishes Ryedale from larger, more transactional competitors.

With nearly two decades of operational history, ATTMA accreditation, UKAS-calibrated testing equipment, and a comprehensive in-house service offering spanning air permeability, acoustics, ventilation performance, energy rating, and architectural design, Ryedale Testing is a well-credentialled building compliance partner for any developer or main contractor operating under UK Building Regulations. Its base in Ryedale, North Yorkshire, and its established nationwide coverage across the UK make it readily accessible to projects throughout England and beyond.
