What’s the Difference Between Regulated and Unregulated?
- Regulated sectors, such as gas, electricity, ventilation, and specific structural work, are governed by law. Tradespeople must be registered, qualified, and assessed through formal Competent Person Schemes.
Examples of regulated activities include:
-
- Electrical work (Part P of the Building Regulations)
- Gas installations (Gas Safe Register)
- Asbestos removal
- Some domestic ventilation works (Approved Document F)
- Some fire safety and structural works
- Unregulated sectors, such as general building, decorating, and home maintenance, do not require formal qualifications or legal oversight. But that doesn’t mean they’re without standards. Much of this work involves building regulations approval unless it is carried out by an installer who can self-certify under a Competent Persons Scheme.
Competence in Unregulated Areas
Professionals in unregulated sectors often choose to evidence their competence voluntarily by joining recognised trade bodies and certification schemes managed by NHIC members, including:
- Federation of Master Builders (FMB)
- Chartered Institute of Building (CIOB)
- FENSA – for replacement windows and doors
- Certass, DGCOS, HIES, GGF, QANW, and others
These organisations uphold high standards by requiring:
- Verified technical knowledge and experience
- Clear codes of conduct
- Ongoing training and CPD
- Consumer redress and dispute resolution processes
Competence in Regulated Sectors – Including Ventilation
In regulated sectors, demonstrating competence is a legal requirement. NHIC members play a leading role in these areas—for example:
- EnviroVent, a specialist in mechanical ventilation systems, offers solutions that comply with Approved Document F standards for domestic ventilation. Their work supports healthier homes and ensures compliance with building regulations.
Why It Matters – Especially Now
As more homes are improved and upgraded to meet modern energy, water and safety standards, projects often involve a mix of work—some regulated, some not. From insulation and ventilation to windows and general repairs, success depends on competent people delivering high-quality outcomes.
When regulation doesn’t apply, voluntary accreditation through trusted NHIC member organisations helps fill the gap, providing consumers with confidence and tradespeople with recognition.
Homeowners are responsible under the Building Safety Act 2022 for ensuring that they only employ suitably competent and experienced designers and contractors
Why Competence Counts – What to Look for When Hiring a Home Improvement Professional
| Competent, Accredited Professional | Unverified Tradesperson | |
| Training & Qualifications | Demonstrates formal training, up-to-date knowledge, and often CPD | Unknown skill level or outdated knowledge |
| Membership | Member of a recognised trade body (e.g. FMB, FENSA, CIOB, Certass) | Not part of any professional scheme or body |
| Consumer Protection | Covered by guarantees, codes of conduct, and dispute resolution schemes | No consumer protections or independent complaints process |
| Compliance | Understands and works within current building regulations and standards | May not comply with safety, energy, or legal standards |
| Peace of Mind | Trusted reputation, transparent reviews, and accountability through membership organisations | Harder to verify experience or performance |
| Value for Money | High-quality work that lasts, adding long-term value to your home | May result in hidden costs, poor finish, or future remedial work |
| Insurance Coverage | Holds appropriate public liability and employer insurance | May not be insured — leaving homeowners exposed |
| Contracts & Paperwork | Provides written quotes, contracts, and receipts | Often informal, with limited documentation or guarantees |
| Sustainability Awareness | Understands low-carbon options and sustainable materials; supports greener home improvements | May not offer or understand energy-efficient or compliant solutions |
| Verified Identity | Listed on public registers (e.g. TrustMark, LABC Front Door, FENSA) | Difficult to trace or verify identity |

A Note to Tradespeople
If you’re a tradesperson working in an unregulated sector, joining a professional organisation is one of the best ways to showcase your commitment to quality. NHIC and its members offer access to accreditation, training, consumer assurance, and ongoing professional development, supporting your business and fostering customer trust.
Well-being Matters Too
At NHIC, we also recognise that professionalism includes well-being. A thriving home improvement industry is one where mental health, safety, and respect are valued across every trade and every site.
Final Word: It’s Not Just About Regulation – It’s About Competence
While regulation provides legal safeguards, competence builds lasting trust.
What matters is:
- Can the person prove their skills and training?
- Are they part of a professional community?
- Do they work to high standards, regardless of legal obligation?
At NHIC, we believe that competence, professionalism, and accountability are the cornerstones of a quality-built environment, whether your trade is regulated or not.
