The Building Safety Act is part of the building safety legislation produced in the wake of the 2017 Grenfell Tower disaster.

It’s aim is to;

  • Enhance safety standards
  • Ensure accountability
  • Maintain thorough documentation throughout a building’s lifecycle

The Building Safety Act for Homeowners – Does the Building Safety Act apply to you and your project?

If you are undertaking works that requires Building Regulations approval – Yes absolutely!

There is a misconception that the Building Safety Act only applies to high rise buildings – this is not the case. It applies to ALL construction projects where you have to apply for Building Regulations approval.

The Building Safety Act will change the way buildings are designed, constructed, and managed.

The Act enables the introduction of new regulations covering the competence of all those who undertake building work with new statutory roles for Designers and Contractors on all projects.

Who are duty holders?

  • clients (homeowners, developers, employers)
  • designers
  • principal designers
  • contractors and
  • principal contractors

What does it mean for you as a homeowner?

As a client (dutyholder), you are legally responsible for:

  • Appointing competent professionals to design and build your project.
  • Sharing relevant information related to your project.

What you need to do

When a building regulations application is submitted, you (the client and homeowner) have to declare who is taking on the principal designer duties – you have to be confident they are a competent designer.

Similarly, when you appoint a builder as principal contractor then you need to be confident they are a competent builder.

Both need to deliver your project such that it complies with the Building Regulations..


Typically, your designer will serve as the Principal Designer, and your builder will act as the Principal Contractor.


The changing role of Building Control

Building Control will no longer be able to advise how to comply with Building Regulations – it will be a simple

  • yes it’s compliant or 
  • No it’s not compliant– this applies at plan checking stage and on site

It is up to the competent designer to produce a compliant design and the competent builder to build to the approved design.

Enforcement and Penalties

A breach of duties by any dutyholder is a criminal offence. Failure of a duty holder to carry out their duties will be addressed via fines and a custodial sentence up to 2 years.

Once building work is complete

The dutyholders (Client, Principal Designer and Principal Contractor) are to provide a signed compliance declaration within five days of completion of the work confirming:

  • To the best of your (the client’s) knowledge the work complies with the Building Regulations.
  • The Principal Designer and Contractor both have to sign to say they have fulfilled their duties.

Potential pitfall: When a builder wants to make a change to the approved design

If there are design changes from the information declared as compliant by the Principal Designer (and approved by Building Control in their checking role) a competent designer needs to confirm that the design remains compliant.

You (the client) would be responsible for providing the relevant information or seeking assistance (from the Principal Designer) with the design element. 

Alternatively if you felt your builder was a competent designer you would need to declare a change of dutyholder and assign your builder as the new Principal Designer.

What happens once the build is finished?

Before Building control will carry out a final completion inspection, the client, the Principal designer and Principal contractor have to sign a “declaration of compliance” to say they are happy that they have carried out their duties under the act and the build is compliant with building regulations.

What happens if I can’t do this?

Building Control will not be able to issue a completion certificate, which may be an issue when you come to sell your property.

Today I’m talking to Andrew Wiggett, one of our latest Structural Engineers to pass his Chartered exams.

Why Did You Choose To Study Structural Engineering?

When I was a school I didn’t really know what I wanted to do.

I chose the A levels that were interesting and “do-able” – Maths, further maths and physics and chemistry AS

I didn’t know what engineering was, or that you could do a degree in it

I thought I was going to do a Physics degree, or I looked at Medicine – but that was an idea that died out pretty quick!

In lower 6th form someone suggested looking at Engineering, I thought that’s a good idea – this is what I pictured physics to be like.


I did a general engineering degree at Cambridge University – 4 year Masters

My best module in first year was structures and materials – my two favourite subjects. I tried to avoid pure Maths, but there was a lot of this.


What Do You Like About Being An Engineer?

It’s a varied job, with lots of projects on the go at the same time.

I’m glad that none of my projects take too long, I wouldn’t like to be working on a project that had a two year deadline .. I wouldn’t know where to begin with that. Whereas twenty things to do in the next month is a lot more interesting.

Any Downsides To Structural Engineering?

Lack of protection of the name “Engineer” A friend said once they did a two day course installing BT infinity and now they were an “Engineer”

People come up to me and say “you’re an engineer, why can’t you do this task” it’s usually sawing a bit of wood in a straight line!

What Skills And Qualities Do You Think Are Important To Become A Structural Engineer?

Maths, but not someone who gets bogged down in the exact details.

Rejecting the negative answer out of hand and explicitly state it, it would drive pure mathematicians bonkers.

The ability to visualise things. That why I always struggled with the electronics side of things at university because it was something that I couldn’t picture. Whereas building structures I can picture as well as the mechanics and materials.

Communication skills There’s no point knowing the answer if you can’t tell someone what it is and there is no point designing something that a Contractor can’t build.

What Was The Exam Preparation Like?

I’d advise you doing the January exam, if you are like me and don’t like Christmas!

A big chunk of my revision was based around past papers, but I didn’t actually sit down and do a whole paper for 7.5 hours.

I started by working on basic scheme design. Coming up with two distinct schemes for a question. Choosing questions that I wouldn’t necessarily pick in the exam. Then I’d move on to the sketch drawings.

Any Tips?

I did prepare a folder of how to do calculations by hand – the sorts of calculations that would come up and set up so I could copy them out – much faster than just having the formula or procedure to hand.

The scheme design was what I concentrated on as that was the part I failed the first time.

I also worked on the end of the afternoon – the method statement. As this was something that I rushed badly last year, but you pick up some good marks here. There are 10 marks out of 50 available in part B – 40/45 minutes. I stopped what I was doing in the exam when I had 45 minutes to go and concentrated on the method statement.

You find out if you fail or pass.

If you fail you get a mark and feedback, but no mark if you pass. However there is a “best solution prize” – it’s across all the papers, across the world.


What Does Becoming Chartered Mean to you?

 It’s sort of the next step in my career.

I remember doing the first graduate interviews for my first job after University and they’d always say “where do you see yourself in 5 years” … Annoyingly it’s taken me 5.5 years – but I got there!


Do You Have A Favourite Building Structure?

 I’m a big fan of timber.

From a sustainability point of view, timber structures are the way things are going especially in this country.

Design lives of buildings are much more suited to timber, rather than putting up concrete and brick monstrosities to be then torn down in 40 years.

It’s like electric cars, we can’t all switch to timber overnight, there’s not enough of it. I think we need to push things in that direction, it’s slightly better.
