About Slate Compliance
North Wales' trusted property compliance specialists — accredited, insured, and built around the needs of letting agents, HMO landlords, and holiday let operators.
More Than an EPC Provider
Slate Compliance was founded to give property owners, residential landlords, and estate agents across North Wales a single, reliable source for every compliance and energy assessment they need. What began as a focused EPC service has grown into a comprehensive property compliance hub — covering Energy Performance Certificates, PAS 2035 Retrofit Assessments, Legionella Risk Assessments, Electrical Equipment Testing (EET), professional 2D & 3D floor plans, launching January 2027 — BS 5839-6 Fire & Carbon Monoxide Compliance auditing.
We are deeply familiar with the North Wales property landscape — from the Victorian terraces of Bangor and the traditional stone cottages of rural Gwynedd to the mix of modern and period homes across Anglesey. That local knowledge, combined with our full suite of accredited compliance bundles, means you get accurate assessments, legally valid documentation, and a team that genuinely understands the properties it works with. This deep geographic expertise is backed by an official Elmhurst Level 3 Qualification in Traditional Buildings, ensuring historic and heritage properties receive elite technical accuracy.
Accuracy
Every assessment is conducted thoroughly and reported precisely. Correct documentation protects your legal position, your tenants, and your investment.
Speed
We know delays cost money. Certificates and reports are typically issued the same day or next working day after assessment — keeping your projects and listings on schedule.
Transparency
No hidden fees, no jargon. We tell you exactly what to expect before we arrive and deliver precisely what we promise — every time.
Our Accreditations
Our credentials are not just badges — they are your assurance that every report we issue is accurate, legally valid, and professionally delivered.

Traditional Buildings Certified
Elmhurst Level 3 — Traditional BuildingsOur assessors hold the specialist Elmhurst Level 3 Qualification in Traditional Buildings. This advanced certification provides letting agents and landlords with complete confidence that older, solid stone, and period property portfolios across North Wales are evaluated using proper heritage construction frameworks.
Deep Local Knowledge
North Wales has a diverse and distinctive property stock. We know it well.
From the Victorian and Edwardian terraces of Bangor city centre to the traditional Welsh stone cottages of rural Gwynedd, and the varied mix of modern and period properties across Anglesey — North Wales properties have their own characteristics. Solid stone walls, older heating systems, and traditional construction methods all require an assessor who understands what they are looking at. We do. That same local expertise underpins every compliance pack we offer, from energy assessments and water safety to electrical equipment testing and, from January 2027, comprehensive fire and carbon monoxide alarm auditing.
