“We Know Who’s Competent, We Just Can’t Prove It”: The Most Dangerous Sentence in Construction

Most construction firms in the UK can name their best workers without a second thought. Far fewer can hand over a file that proves it. That shortfall has become one of the biggest compliance risks in the sector. Under the current rules, a main contractor, an auditor, or a regulator will not accept skill on trust. 

They expect records, and firms without them lose out no matter how capable their workforce is. In short, proving competence in construction now carries the same weight as the competence itself. 

The sections below explain where the demand for proof comes from, what the law requires, and how any firm can build a record system that stands up to scrutiny.

Why Word of Mouth Fails at the Pre-Qual Stage

When a principal contractor vets a subcontractor, one question sits at the heart of it. Can you show us that your workforce is competent? Trust inside the firm counts for nothing here. The compliance team wants records. They expect skills matrices, test results, tickets and review dates that match the scope of work.

If those records do not exist, the spoken word fills the gap. And the spoken word fails. It will not pass a pre-qual form, the Common Assessment Standard or a duty holder’s checks. The result is blunt. The package goes to the firm whose paperwork stands up.

What the Building Safety Act Asks of You

For decades, the trade policed its own skills. A worker was competent because the boss said so, and that was usually enough. The Grenfell Tower fire in 2017 ended that era. The public inquiry that followed asked a hard question: how did unfit work pass through so many hands unchecked? Dame Judith Hackitt’s review answered. 

The trade’s approach to competence was fragmented. Different bodies used different frameworks. There was no sound way to check skills across trades, and no one owned the problem. Her findings led straight to the Building Safety Act 2022. 

The Act replaced informal trust with clear legal duties and placed the burden of proof on the people doing and managing the work.

The rules now place these demands on the supply chain:

• Individual competence: anyone undertaking building or design work in England must possess the right skills, knowledge, experience, and behaviours for the task. The trade calls this SKEB.
• Organisational capability: firms must run a system that tracks competence across the whole workforce, subbies included.
• Duty holder checks: clients, principal designers and principal contractors must check the competence of those they appoint before work starts.
• Regulator oversight: on higher-risk buildings, the Building Safety Regulator can inspect competence records. Building control bodies check them on other jobs.
• Long-tail liability: the Act stretched the time limits for claims over defective work. Records you keep today may be needed as proof long after handover.

The End of Grandfather Rights

Nothing showed the shift more clearly than the loss of Industry Accreditation from the CSCS scheme. These cards, often called grandfather rights, were issued on an employer’s say-so rather than a formal ticket.

That route has closed. Renewals stopped, and the remaining cards expired. To stay carded, workers now need a recognised qualification or membership of an approved professional body. Skilled workers with years on the tools found their proof had lapsed, even though their skill had not changed. 

The Construction Leadership Council drove this change. It requires all card schemes carrying the CSCS logo to sit on recognised qualifications. The message is the same one the Act sends to firms. Skill without proof no longer opens the gate.

Building a Simple Competence System

Meeting these duties does not need a compliance team. Guidance from BESA and the BS 8670 family of standards backs a scaled approach. For an SME, a well-kept record system with clear role profiles is an accepted starting point. A sound system tends to include these parts:

• Role profiles: for each high-risk task, write down the skills, knowledge, experience and behaviours a competent worker needs.
• Skills matrix: map your workforce against those profiles. Gaps then show up before work is handed out, not during an audit.
• Supporting proof: keep tickets, records of finished work, RAMS the worker has written, toolbox talk registers and supervisor sign-offs.
• Experienced worker routes: workers without formal tickets can gain one through an on-site assessment. No one has to go back to college.
• Allocation and review: hand out work based on what the matrix shows. Review it at set points and record how gaps are closed.

Run this way, and competence management becomes part of normal site admin. It stops being a panic job before a tender or an audit.

Making Competence Visible On Every Project

A competence system does not replace sound judgement. It makes that judgement plain to the regulator, the insurer and the duty holder who appoints you. Firms that treat proving competence in construction as daily practice gain ground at pre-qual, pass gateways with less friction and cut their exposure to claims. 

If your firm still sees itself in the sentence at the top of this page, the fix starts small. Pick one trade. Write the role profile. Build the matrix and gather the proof. Once the records match the skill, the most dangerous sentence in construction no longer applies to you.
