Understanding which installed building services must meet Building Regulations helps explain why the boiler is the best example. A boiler is a fixed heating system that involves fuel combustion, a water circuit, and a vent or flue. Because it deals with flammable fuel, exhaust gases, and safe water and electrical connections, its installation must satisfy safety and performance standards set by Building Regulations. In many places this means using a suitably qualified installer, such as a Gas Safe professional, and ensuring the work complies with relevant parts of the regulations (for example, safety, energy efficiency, and electrical safety as applicable). That combination of being a fixed, safety‑critical service makes the boiler a controlled service.

Sofas and curtains are furnishings, not services installed as part of the building’s mechanical or electrical systems, so they don’t fall under the same installation requirements. A window is part of the building envelope and has its own regulatory considerations, but it isn’t classified in the same way as a controlled service that must comply with building regulations upon installation.
