MTC Test Quick Guide – January 2021

Urgent MTC Test Information

We are now commencing the online MTC knowledge tests through GQA and I cannot stress enough the
importance of all having a general understanding of the Building Regulations.

As an aid to the main revision document (Jan21v3) summarised below are the Approved Documents
and some key information that must be revised before taking the test.

It is suggested that Installers are given at least 1 hour to prepare and make final revisions before
starting the test.

Urgent MTC Test Revision

Approved Document A - Structure

With regard to windows and doors, Approved Document A applies to bay windows and other
windows that are load bearing, e.g. where lintels have not been used. When replacing windows and
doors it is vital that the integrity of any existing structural support is not compromised.

Approved Document B – Fire Safety
A fire escape window should have an unobstructed openable area that is at least 0.33m² and at least
450mm high or 450mm wide. If one of the dimensions is at the 450mm minimum, then the other
dimension will need to be at least 734mm to achieve 0.33m². The route through the window may be
at an angle rather than straight through.
The bottom of the openable area should be no more than 1100mm above the floor.

Approved Document K Protection from falling, collision and impact specifies a minimum guarding height
of 800mm, except in the case of a window in a roof where the bottom of the opening may be 600mm
above the floor.

Approved Document C – Site Preparation and Resistance to
Contaminants & Moisture

Interface between walls, doors & windows. Resistance of joints between walls, doors & windows to
resist penetration of rain and prevent damage to the building & damp-proof courses to direct moisture
outside.
