You’re not just being asked to BE competent — you’re being asked to prove it.
Most installers don’t think about fire safety competence like that — and most Responsible Persons don’t realise they’re expected to.
As an installer, you train.
You gain experience.
You do the work properly.
That is competence.
But that’s not what gets tested if something goes wrong.
Fire Safety Competence Requirements (UK Law Explained)
In practice, the system works like this:
- The Building Safety Act 2022 set the wheels in motion and the competence duty now sits in Regulation 11F of the Building Regulations 2010 (introduced via Part 2A in 2023). It requires individuals to have the necessary skills, knowledge, experience and behaviours (often referred to as SKEB) — and Regulation 11F(4) specifies those behaviours include refusing to carry out work beyond their skills, knowledge or experience. Where the appointee is a company, organisational capability is required
- The Regulatory Reform (Fire Safety) Order 2005, Article 18 requires the Responsible Person to appoint one or more competent persons to assist with the preventive and protective measures
But neither of these tells anyone:
how that competence should be proven
So when something is challenged later — by an insurer, an investigator or a court — the question isn’t:
“Were they competent?”
It becomes:
“Can the Responsible Person prove they were competent?”
From the Other Side of the Decision
The reality for the Responsible Person is this:
In most cases, they aren’t a fire safety expert.
But under Article 18 of the Fire Safety Order, they are still expected to make decisions about competence.
Which often means relying on:
- what they’re told
- how confident it sounds
- and what looks credible on the surface
So when a contractor says:
“We’re competent”
“We’re compliant”
There’s a natural tendency to accept that.
Where the Risk Really Sits
This isn’t tested at the point of decision.
It’s tested later.
When something is reviewed, investigated or challenged, the focus shifts to:
“What evidence was there that this was the right choice?”
Not how confident it sounded.
But:
what was actually relied on
How to Prove Competence in Fire Safety (The Evidence Stack)
Competence is built from layers of evidence.
1. Third-party certification (company level)
Shows:
- independent assessment
- systems and processes
- some level of audit
Valuable from a decision-making point of view.
But it doesn’t prove:
the individual engineer doing the work was competent for that job
2. Individual qualifications (person level)
Shows:
- training
- knowledge at a point in time
But not:
consistent real-world competence
3. Skills, Knowledge, Experience and Behaviours (SKEB)
- Skills → can they do it?
- Knowledge → do they understand it?
- Experience → have they done it enough?
- Behaviours → do they act within their limits?
This is the legal benchmark set in Regulation 11F of the Building Regulations 2010.
Regulation 11F(4) is specific about what the “behaviours” element actually means — it includes refusing to carry out non-compliant work, cooperating with others and refusing work that is beyond a person’s skills, knowledge or experience.
4. The Missing Layer — Evidence of the Decision (Responsible Person)
This is what most people overlook.
It’s not just:
- what the contractor has
It’s:
- what was checked
- how they were selected
- why that decision was reasonable
Because if something goes wrong, the question becomes:
“What did you rely on to decide they were competent?”
This is where Article 33 of the Fire Safety Order comes in — primarily for the Responsible Person.
It allows a defence of due diligence — but only if the Responsible Person can show they:
- took all reasonable precautions
- exercised all due diligence
Which means:
It’s not enough for a contractor to claim competence. It’s not even enough for them to BE competent.
The Responsible Person must show how they satisfied themselves of it.
That’s what gets tested — and only evidence will pass the test.
Why This Still Feels Inconsistent
As an experienced installer, you might be thinking:
“We’ve never been asked for any of this.”
Or as a Responsible Person, you might be thinking:
“I’ve never had to ask for this before.”
Both are often true.
Because day-to-day, nothing forces the question. It’s only when something goes wrong — a fire, an investigation, a claim — that anyone starts asking who was competent and how it was proven.
By then, the answer either exists or it doesn’t.
Where Third-Party Certification Helps — And Where It Doesn’t
Certification gives:
independent evidence that someone has been assessed
Third-party certification doesn’t exist in isolation. It sits on top of British Standards (which define what good looks like), schemes like BAFE or NSI (which turn those standards into requirements installers can be assessed against) and membership bodies like the FIA or BSIA (which add another layer of professional assurance). When a contractor says they’re “third-party certified,” that’s the chain you’re relying on.
From a Responsible Person’s perspective, that helps answer:
“Did I rely on something reasonable?”
But it does not guarantee:
- every individual engineer is competent
- the task is within scope
- the work is correct in that instance
So:
It supports a decision — it doesn’t replace it
Training vs Proving Competence
Training shows learning.
Competence requires:
- understanding
- application
- consistency
- independent verification
When training and assessment sit too close together, the line between:
- “has learned”
- “can do”
becomes blurred.
Turning SKEB into Real Questions
For the Responsible Person:
- Skills → “Can you show examples of this exact work?”
- Knowledge → “What standards are you working to?”
- Experience → “How often do you do this?”
- Behaviours → “What do you do if something is outside your competence?” (this question maps directly to Regulation 11F(4) — refusing work beyond your competence is a legal behaviour, not just good practice)
These are not technical questions.
They are decision questions.
What This Means for Installers
Those questions shape how you need to respond.
It’s no longer enough to say:
- “We’re accredited”
- “We’re trained”
- “We’ve been doing this for years”
You need to show:
- who will do the work
- how their experience applies
- what standards you follow
- how you operate in practice
- where your limits are
Because your customer is buying:
confidence they can defend their decision to choose you
This is the angle we cover in more depth in marketing your SKEB — turning the same competence evidence the law expects into the marketing that wins work.
What Happens When You Can’t Prove It
The issue doesn’t show up immediately.
It appears later:
- after a fire
- during an investigation
- during an insurance claim
Then the focus becomes:
“Who did the work — and how was their competence established?”
If that trail is unclear, the party who can’t evidence their part is the one left holding the risk.
What Good Looks Like in Practice
Good decisions are built on:
- multiple forms of evidence
- aligned to the actual work
- documented at the time
For the Responsible Person (Article 18 + Article 33)
- what you relied on
- what you checked
- why the decision made sense
For the installer (Regulation 11F)
- evidence your competence clearly — not just state it
- refuse work that falls outside your skills, knowledge or experience
The Shift That’s Happening
From:
“Getting the job done”
To:
“Being able to prove the job was done properly — and that the right person was chosen”
The Question That Really Matters
So, for installers, instead of leading with:
- “We’re accredited”
- “We’re qualified”
- “We’re competent”
The stronger question is:
“Can we help our customer prove they made the right choice by choosing us?”

Final Thought
You’re not just being asked to be competent in fire safety — you’re being asked to prove it.
FAQs
Do you need third-party certification to prove competence in fire safety?
No — it is not a direct legal requirement under the Fire Safety Order or Regulation 11F of the Building Regulations 2010. But it is one of the most recognised forms of independent evidence and is often relied upon to help demonstrate competence if a decision is challenged.
What is SKEB in fire safety?
Skills, Knowledge, Experience and Behaviours — the four factors used to assess competence, defined in Regulation 11F of the Building Regulations 2010.
Who is responsible for proving competence?
Both the contractor and the Responsible Person. Under Regulation 11F, the contractor must evidence competence. Under Article 18 of the Fire Safety Order, the Responsible Person must appoint competent people — and if challenged, Article 33 provides a defence — but only where they can show how they satisfied themselves that those people were competent.
Is training enough to prove competence?
No. Training shows learning. Competence under Regulation 11F requires application, consistency and the behaviours that go with it — including refusing work that is outside your skills, knowledge or experience.
Why does evidence matter?
Because competence is usually tested only when something goes wrong — a fire, an investigation, an insurance claim. That’s when decisions must be justified with clear evidence, particularly where Article 33 of the Fire Safety Order is being relied on as a defence.
This article is for general information about how UK fire safety competence requirements work in practice. It is not legal advice. Where competence, due diligence or specific legal duties are in question — particularly in the context of an investigation, prosecution or insurance claim — readers should seek advice from a qualified solicitor or fire safety specialist.
