Building Control Guide

Does Your Project Need Building Control?

Building control applies whenever your project needs to meet building regulations. For many conservatories that qualify as exempt, building control is not required, provided the structure stays within the specific exemption conditions. However, orangeries and extensions almost always fall within its scope because of their solid walls, larger roofs and permanent use as integrated living space.

Building control is also triggered when you replace a lightweight glazed roof with a solid tiled one, or when you remove the dividing doors between a conservatory and your home. In short, the more your project resembles a permanent extension of the house, the more likely building control will apply.

Glazed Roof vs Solid Tiled Roof: What You Need to Know

The difference between a glazed roof and a solid tiled roof is one of the most important factors in understanding building control for your project.

Glazed roofs are lighter and allow plenty of natural light into the space. When fitted as part of an exempt conservatory, they often do not trigger building regulations, provided all the other exemption conditions are met.

Solid tiled roofs offer better insulation and make a space feel more like a permanent room. Because of their additional weight, the existing structure and foundations must be checked to confirm they can safely carry the load. This usually means building regulations approval is required, including inspections to verify the work meets the necessary standards.

This is why it is so important to seek expert advice before replacing a roof for your Gloucestershire home. What seems like a simple upgrade can change the legal status of your whole structure.

From Foundations to Finish: What to Expect

The process usually begins with one of two routes. A full plans application means your drawings and specifications are approved before work starts, giving you certainty from the outset. A building notice is better suited to smaller projects and allows work to begin sooner, with inspections carried out as the build progresses.

During the build, a building control officer will inspect key stages such as the foundations, structural work, drainage and insulation. Once everything is complete and meets the required standards, you receive a completion certificate. This is an important document that proves your project was carried out correctly, and it is often requested when you come to sell your home.
