What Star General does
Star General is a Southampton-based UK private limited company, founded in 2020, that delivers domestic energy assessment services to property owners and intermediaries in Hampshire and surrounding postcodes (SO, PO, RG, GU, BH, SP). Its core service offering comprises Energy Performance Certificates (EPCs) required for property sales and rentals in the UK, PAS 2035-compliant Retrofit Assessments that enable homeowners and landlords to access government-funded schemes (ECO4 and the Great British Insulation Scheme), and MEES compliance guidance for landlords facing Minimum Energy Efficiency Standards enforcement. Customers include individual homeowners, private landlords, letting agents, estate agents, property managers, and social housing providers.
Underlying the assessment services is a multi-tenant SaaS platform offered to other Domestic Energy Assessors on a Free tier (up to 5 bookings per month) and a Pro tier (unlimited), with booking management, Stripe-integrated invoicing and payments, Twilio SMS notifications, Gmail email delivery, ReadNotify tracking, a customer-facing self-serve portal, and batch invoicing targeted at estate agents. The platform is marketed as available UK-wide, even though physical assessments remain Hampshire-centric. The technology stack is composed of commodity third-party integrations rather than proprietary infrastructure.
The business operates on a bootstrapped basis with 1-10 employees, no disclosed external funding, and no documented M&A, partnerships, or leadership hires. Revenue is generated from unit-priced EPCs and Retrofit Assessments on a pay-per-engagement basis, supplemented by SaaS subscription fees from other DEAs. Go-to-market relies on a self-serve online booking portal supported by phone, email, and WhatsApp as direct outreach channels, with regional search presence in the Hampshire catchment.

Star General competitors and assessment
Company assessmentOthers
- RICS: Royal Institution of Chartered Surveyors — global professional body for property professionals including surveyors and estate agents. Comparable as an ecosystem participant because RICS-accredited surveyors and estate agents are part of Star General's customer base and referral network.
- ServiceM8: Field service management SaaS for trades and service SMBs with mobile job management, invoicing, and payments. Comparable to Star General's multi-tenant SaaS for DEAs on the SaaS-for-trades-service-businesses dimension, though broader in target verticals.
- TrustMark: UK government-endorsed quality scheme covering tradespeople and retrofit/property professionals. Relevant ecosystem participant because TrustMark-registered contractors are the audience for ECO4/GBIS retrofit work that flows downstream from Star General's PAS 2035 assessments.
- Jobber: Field service management SaaS serving small trades and service businesses (HVAC, plumbing, cleaning, property services). Comparable as an adjacent SaaS serving the same SMB customer profile with booking, invoicing, and payment workflows that Star General's DEA platform also delivers.
Direct peers
- Elmhurst Energy: UK's leading DEA accreditation scheme and one of the largest energy assessor networks, also offering software tools for assessors. Direct comparable because it operates in the same accredited DEA + software + EPC delivery space, serving landlords, homeowners, and property professionals across the UK.
Broad incumbents
- BRE Group: Building Research Establishment operates as a broader built-environment science and standards body, providing BREEAM, certification, and energy assessment services. Comparable as a much larger incumbent in the energy/building compliance space, though Star General focuses narrowly on residential EPCs while BRE spans the full property lifecycle.
