Facade refurbishment will give your building a visual uplift, with smart lines, cleaner finishes and improved thermal performance. But behind the fresh cladding or renewed render is something more technical.
Working on a building’s external facade, you have to deal with access at height, structural interfaces, hidden defects, fire performance considerations, weather exposure and public risk. It’s a far cry from a tidy-up job.
The work might look minor on paper, replacing a few panels, repairing flashing, and patching damaged cladding. But in reality, even small facade interventions are construction work, and in the UK, it’s governed by a strict legal framework.
Compliance isn’t just about paperwork for the sake of it. Getting the basics right under CDM 2015 helps you plan properly, reduce risk, and avoid the kind of site incidents that turn a refurbishment into a headline.
Understanding what CDM regulations are and how they apply specifically to facade refurbishments keeps your project on the right side of the law. It lays the foundation for a safer, smoother job from day one.
What are CDM regulations?
When people ask, “What are CDM regulations?”, they’re referring to the UK’s main legal requirements for managing health and safety on construction projects.
What does CDM stand for?
CDM stands for the Construction (Design and Management) Regulations 2015, often shortened to CDM 2025. These regulations apply across the UK and cover most construction work, from small repair jobs through to large-scale developments.
What are CDM regulations designed to do?
CDM 2015 are a set of rules that manage health, safety and welfare across construction projects in the UK. The regulations are designed to ensure that safety is at the forefront, and not treated as an afterthought once scaffolding is up and work has begun.
CDM regulations help to make sure that:
- Risks are identified early
- The right people are appointed at the right time
- Everyone understands their responsibilities
- Site work is planned and managed in a coordinated way.
Do CDM regulations apply to facade refurbishment?
The short answer: Yes.
CDM 2015 applies to all construction work, including maintenance, repair, refurbishment, and redecoration, not just big builds. If your facade project includes planning, specialist access, design decisions, or contractor-led works, it will almost always fall under CDM.
This matters because facade work often appears to be straightforward replacement or repair. Still, it brings high-risk activities into play: working at height, lifting operations, temporary works, falling object risk, and public interface. Under CDM, these risks must be managed properly from the start.
Facade-specific tasks that CDM covers
Facade refurbishment is firmly within CDM’s scope. Some examples of facade-related works that are covered include:
- Unitised curtain wall replacement
- Rainscreen cladding inspections
- Glass replacement (including high-level glazing, spandrels, and curtain wall panels)
- Cladding panel repairs and re-fixing programmes
- Sealant replacement, gasket renewals, and facade weatherproofing
- Remedial bracketry/fixings, subframe works, and corroded component replacement
- Fire-stopping remediation
- Balcony edge, soffit, and facade interface repairs
Notifiable projects: When the HSE must be told
Not every facade refurbishment is notifiable, but some are. A project becomes notifiable to the Health and Safety Executive (HSE) when it meets either of these thresholds:
- Lasts longer than 30 working days and has more than 20 workers working simultaneously at any point; or
- Exceeds 500 person-days of construction work (for example, 10 workers over 50 working days).
Key roles and responsibilities in facade projects
Facade refurbishments often involve a mix of survey work, design decisions, specialist access, sequencing constraints, and materials with performance implications. CDM clarifies who is responsible for what, which is especially useful on envelope projects where multiple parties overlap.
Here’s a breakdown of the key roles:
| Role | Primary responsibilities for façade refurbishments | What this looks like in practice |
| The Client (building owner, landlord, managing agent, or whoever commissions the work) | Sets the project up properly: appoints the right people, ensures competence, provides pre-construction info, and allows adequate time and resources. | Appointing a Principal Designer and Principal Contractor (where required), ensuring surveys/asbestos info are shared, not pushing unrealistic timelines that increase risk. |
| Principal Designer (PD) | Manages health and safety during the design and planning phase. Coordinates designers, identifies and mitigates foreseeable risks, and ensures key information is communicated. | Considering safe access for installation and future maintenance, designing out fragile zones, coordinating details around interfaces, and assessing cladding/material choices with safety in mind. |
| Principal Contractor (PC) | Manages health and safety on-site and coordinates construction activities. Plans the works, controls site risks, and manages contractors. | Scaffold and hoist plans, exclusion zones, dropping-object controls, lifting plans, permits, RAMS coordination, public protection, and sequencing works to reduce exposure at height. |
| Designers (architects, façade consultants, engineers, specialist subcontract designers) | Eliminate, reduce, or control risks through design and provide design risk information. | Selecting systems that can be installed safely, reducing manual handling where possible, designing robust fixing strategies, and ensuring interfaces don’t create new hazards. |
| Contractors (trade contractors, façade installers, access providers, glaziers) | Plan and carry out work safely, follow the construction phase plan, provide RAMS, and manage workforce competence and supervision. | Method statements for panel removal/replacement, glass handling plans, controlled waste removal, tool tethering, edge protection, training and supervision for high-risk tasks. |
Facade-specific risks to manage under CDM
CDM is a framework designed to ensure that any real-world risks are identified early and can be controlled on-site. Facade refurbishments carry a risk profile, as they combine height, complex interfaces, temporary works, and public exposure.
Working at height
Whether you’re using scaffolding, MEWPs, or cradle/suspended access, the hazards are predictable, which means they’re also preventable.
Structural integrity
Facade elements might be non-loadbearing, but they can contribute to stability, weather tightness, and the behaviour of interfaces. When you remove old cladding, curtain wall bays, or stick systems, you can expose weaknesses you didn’t know were there.
Public safety
Facade work often occurs on buildings that are still occupied. That raises the bar because the public is not trained, not supervised and not wearing PPE.
Fire safety
Material choice, cavity detailing, and interfaces can affect fire performance. CDM connects safety decisions throughout the facade lifecycle: design, installation, and future maintenance.
Choosing a competent partner
CDM compliance is more than just a tick-box; it’s a practical system that protects people, occupants, and your investment. Facade refurbishment carries predictable hazards, such as height, lifting, etc., and the CDM simply demands that these hazards are planned, coordinated and controlled from the start.
Choosing the right partner makes that difference visible on site, with clearer planning, safer sequencing, tighter control of changes and better documentation at handover.
