Where Building Regs Fit Alongside Planning
Planning permission and building regulations are two separate systems answering two different questions: planning asks whether a structure is acceptable in its setting, while building regulations ask whether it is built safely and soundly. A veranda can be entirely exempt from planning permission and still need its structural fixing done properly to a sound standard.
Many open-sided verandas sit outside full building regs
A genuinely open-sided structure, without walls or full glazing enclosing it, is often treated differently from an enclosed glass room, which is more likely to trigger building regulations for matters like glazing safety, ventilation and structural calculations.
Structural fixing still needs to be sound regardless
Even where full building regulations sign-off is not required, the wall fixing, post foundation and beam connections still need to be engineered correctly to safely carry wind and snow loading, since a structure that fails is a genuine safety issue rather than a paperwork one.
Enclosed glass rooms are a different case
Fully enclosed, heated glass room extensions are more likely to fall under building regulations because they function more like a habitable room, bringing in requirements around glazing, insulation and ventilation that an open veranda would not typically face.
Ask for the structural reasoning, not just a certificate
Whether or not formal sign-off applies to your project, a competent installer should be able to explain how post sizing, base fixing and wall brackets were determined for your specific wind zone and span, not simply state that the frame is strong.

Common questions
Are verandas exempt from building regulations?
Many open-sided verandas fall outside full building regulations, but this depends on size, enclosure and specific design, so it should be confirmed for your project rather than assumed.
Does an exempt structure still need to be structurally sound?
Yes, exemption from formal sign-off does not remove the need for safe, properly engineered fixing and foundations, since safety obligations exist independently of the regulatory process.
Do glass rooms always need building regulations approval?
Fully enclosed, heated glass rooms are more likely to require it than open verandas, though the exact position depends on the specific design and should be confirmed for your project.
Who checks the structural fixing has been done properly?
Where building regulations apply, a building control body inspects and signs off the work; where they do not, it relies on the installer's own engineering competence and any structural calculations provided.
In short
Planning and building regulations are separate systems, and while many open verandas sit outside full building regs, sound structural fixing still matters regardless.
