What Argyle Software does

Argyle Software is a UK-based specialist software development company headquartered in Bath, Somerset, that builds accredited calculation engines and data services for the UK energy performance certification market. The company's core products — iQ-Engine and ACE10 — are Government-approved calculation solutions for SAP (Standard Assessment Procedure) and RdSAP (Reduced Data Standard Assessment Procedure) assessments, listed on the BRE Group approved software lists and authorized to generate compliance and EPC calculations for domestic dwellings across England, Scotland, and Wales. On top of these calculation engines, Argyle offers two API products: OED, which provides standardized EPC dataset access by reverse-engineering Open communities data and recalculating through the accredited engine, and SNUG, a consumer-facing API that delivers postcode-based energy lookup with geo-spatial neighbour matching for properties without existing EPCs.

The company serves UK energy industry companies that require access to accredited energy performance calculation engines for regulatory compliance, property transactions, and building regulations. Its business model is API-first, distributing calculation engine capabilities and standardized data through direct API access (OED and SNUG) and licensing of the accredited software (ACE10/iQ-Engine), with revenue generated through licensing and API access fees (pricing not publicly disclosed). Argyle also provides bespoke application development and energy consultancy, positioning itself as both a software vendor and a domain expert advising on the future direction of UK SAP and RdSAP methodology. The company is privately held with no disclosed funding rounds, operates with 11-50 employees, and has no publicly disclosed revenue figures.

Core offering

Argyle Software develops and licenses UK government-approved SAP and RdSAP calculation engines (iQ-Engine and ACE10) used to generate Energy Performance Certificates (EPCs) for domestic dwellings in England, Scotland, and Wales. The company wraps these engines in two APIs — OED, which exposes a standardized EPC dataset recalculated through the approved engine, and SNUG, a consumer-facing energy lookup service that performs postcode-based EPC retrieval with geo-spatial neighbour matching.

Product overview

Argyle Software offers a suite of energy performance calculation products for the UK market. The core offering consists of iQ-Engine and ACE 10, which are accredited calculation engines for SAP (Standard Assessment Procedure) and RdSAP (Reduced Data Standard Assessment Procedure) assessments. On top of these calculation engines, the company provides two API products: OED API delivers standardized EPC dataset access, while SNUG API provides consumer-facing postcode lookup functionality that sits atop OED and delivers user-friendly energy performance information.

Direct peers

• Onsites Energy: BRE-listed UK software provider of accredited SAP and RdSAP calculation tools, targeting the same energy assessor and housing professional segment as Argyle Software.
• Elmhurst Energy: UK-based accreditation body and software provider listed on the BRE Group approved SAP and RdSAP software registers, offering accredited energy performance calculation engines and assessor services that directly compete with Argyle's iQ-Engine and ACE 10.
• Northgate Information Solutions: UK provider of approved SAP/RdSAP calculation software and property data systems for energy assessors and housing providers; overlaps directly with Argyle's calculation engine and EPC data offerings.
• Stroma Software: Approved UK provider of SAP and RdSAP calculation software, energy assessor accreditation, and EPC-related services; competes head-on with Argyle in supplying accredited engines to energy assessors.

Broad incumbents

• Landmark Information Group: UK property data, environmental risk, and energy performance information provider; competes in the broader EPC and property data market where Argyle's OED and SNUG APIs operate, though its portfolio extends well beyond EPCs.
• BRE Group: Building Research Establishment, which maintains the official approved SAP and RdSAP software registers on which Argyle is listed; a broader building science and standards body whose methodologies and accreditation gatekeeper role shape Argyle's market access.

Others

• Watershed Technology: Carbon accounting and climate disclosure platform, adjacent to Argyle's energy data expertise and a potential partner for expanding the OED/SNUG dataset into enterprise carbon reporting.
• Measurabl: Enterprise carbon accounting and ESG data platform; not a direct SAP/RdSAP peer but adjacent in the regulated energy and carbon data software category where Argyle could expand.

Regional players

• Dataloft (dataloft.co.uk): UK-focused property market intelligence and data provider that aggregates EPC and housing data, partially overlapping with OED's standardized dataset use case for portal and lender integrations.

Emerging players

• Sava Energy: UK supplier of accredited SAP and RdSAP calculation software alongside energy assessor training, comparable in scope to Argyle's accredited engine focus though typically positioned for the training-led channel.
