There often seems to be a bit of confusion surrounding replacement doors so we thought we would try and clarify the details in case you are looking to replace the doors in your house.
Since the government extended Building Regulations to cover all replacement glazing in April 2002, as with replacement double glazed windows, replacement doors with at least 50% glazing need certification. Doors with less than 50% glazing do not require certification.
However if the doors are in conservatories, porches, commercial premises or new build properties or extensions they do not come under the FENSA remit, so they would have to be assessed by the local authority building control process. A FENSA certificate would not be issued in this instance.
Another consideration is where is the door located?
Both windows and doors in critical locations need special attention. A critical location is somewhere a person could have an accident and fall through. To protect everybody and prevent this happening, there are specific regulations to be followed.
If the glass in the door comes within 1500mm of the floor level to the start of the glass, it must be safety glass. This is glass that has been toughened or laminated and will include the relevant safety mark. This safety mark should be clearly visible.
What about single glazed doors? Again this is a safety issue and the simple answer is that single glazed doors will not pass building regulations.
There is some great information on external windows and doors on the government’s online Planning Portal website.
To ensure all the measures are met it is wise to use a registered installer such as a FENSA Fitter who has been approved to carry out the work to comply with Building Regulations. Once the work is completed a FENSA certificate will be issued so you can rest assured the door has been fitted safely and with the correct specifications. You also do not have to have an inspection from your local building control as your certificate acts as proof your new door complies with building regulations.
