The Competent Person Scheme (CPS) is a government-approved programme that empowers qualified tradespeople to self-certify their work as compliant with Building Regulations. In 2025, with stricter energy, safety, and accessibility standards, understanding CPS is more important than ever. This article delivers clear, authoritative answers to the most common questions about the scheme to help homeowners, installers, and businesses navigate compliance with confidence.
What Is the Competent Person Scheme?
The CPS was introduced to simplify compliance with Building Regulations in England and Wales. Instead of relying solely on Local Authority Building Control (LABC) inspections, registered installers can self-certify their work. This system is designed to:
- Reduce delays: Work can progress without waiting for third-party inspections.
- Lower costs: Homeowners and businesses save on inspection fees.
- Ensure quality: Only installers who meet rigorous standards can join a CPS.
- Provide legal assurance: Certificates issued by CPS members are recognised for property sales and insurance.
CPS membership is available for a range of trades, including electrical, gas, plumbing, and renewable energy installations. The scheme is overseen by government-approved bodies, ensuring ongoing compliance and consumer protection.
Why Is the Competent Person Scheme Important?
The Competent Person Scheme (CPS) is fundamental to maintaining high standards and legal compliance in the UK’s building and home improvement sectors.

How Does the Competent Person Scheme Work?
Understanding the mechanics of the Competent Person Scheme (CPS) is essential for both homeowners and trades professionals aiming to ensure building work meets legal and safety standards. The scheme is built on rigorous entry requirements, ongoing assessments, and transparent certification procedures.
Homeowners benefit from straightforward access to compliant professionals and receive official documentation confirming that work has been carried out to the latest standards. For installers, the CPS provides a pathway to professional recognition, allowing them to issue compliance certificates directly and maintain a competitive edge in the industry.
2026 Building Regulations: What’s important now?
The Building Regulations are continuing to evolve as the UK moves towards net zero, with a strong focus on energy efficiency, low‑carbon heating and safety in homes and non‑domestic buildings. For Competent Person Scheme (CPS) members, staying on top of these changes is essential, because your work is being self‑certified as compliant every time you notify an installation.
Future Homes and Building Standards on the horizon
The government’s Future Homes and Future Buildings Standards are aimed at cutting carbon emissions from new homes and non‑domestic buildings, with interim changes already in place via the latest updates to Parts L (Conservation of fuel and power) and F (Ventilation). Installers working under CPS schemes need to understand how improved fabric efficiency, airtightness and ventilation requirements affect their designs and product choices.
Low‑carbon heating and hot water
Policy direction is increasingly towards heat pumps, hybrid systems and high‑efficiency boilers, supported by updated guidance in Parts L and G (Sanitation, hot water safety and water efficiency). CPS‑registered gas, plumbing and heating installers must ensure new and replacement systems are correctly sized, efficiently controlled and documented to meet current performance targets.
Ventilation, indoor air quality and overheating
As buildings become more airtight, there is greater emphasis on delivering effective ventilation and preventing overheating, reflected in updates to Parts F and O. Electrical, mechanical and building services contractors working under CPS need to pay close attention to fan performance, ductwork design and control strategies, particularly in new‑build and major refurbishment projects.
Fire safety and electrical/gas safety interactions
Fire safety remains a major priority, with requirements in Part B continuing to influence how services are routed, protected and controlled, especially in multi‑occupancy and higher‑risk buildings. CPS‑registered electricians and gas engineers must make sure their work respects compartmentation, escape routes and fire detection/alarms, and that manufacturer instructions and relevant British Standards are followed in full.
Accessibility and usability of services
Requirements in Part M (Access to and use of buildings) have a growing impact on the positioning and usability of controls, switches, outlets and plant. For CPS members, this means thinking not only about technical compliance, but about how end users will safely operate heating, hot water and electrical systems throughout the life of the building.
Because CPS membership is based on trust and self‑certification, scheme operators expect members to keep pace with these developments through regular CPD, manufacturer training and, where appropriate, formal update courses.
