What a Building Warrant is
A Building Warrant is permission from your council's Building Standards service to carry out building work. It's issued under the Building (Scotland) Act 2003 and is entirely separate from planning permission.
Planning asks whether a home should be built. The warrant asks whether it will be safe, healthy, energy efficient and structurally sound.
Building Warrants are specific to Scotland. England and Wales have Building Regulations approval instead, with a different process, terminology, fee structure and completion process.
Building without a warrant
Under the Building (Scotland) Act 2003 it is an offence to carry out work that needs a warrant without one. A late warrant, applied for after work has started, costs 200% of the standard fee. A Completion Certificate submitted where no warrant was ever obtained costs 300%.
The seven sections of the Technical Handbooks
Your design is assessed against the Building Standards Technical Handbooks, which are split into seven sections.
| Section | What it covers |
|---|---|
| 1. Structure | Loads, wind, snow and ground movement |
| 2. Fire | Means of escape, fire detection and spread of fire between buildings |
| 3. Environment | Drainage, moisture, ventilation and heating |
| 4. Safety | Stairs, balustrades, glazing and electrical safety |
| 5. Noise | Sound insulation between homes |
| 6. Energy | Insulation, airtightness and carbon emissions |
| 7. Sustainability | The sustainability label and statement |
- 1Structure: foundations, frame, floors and roof.
- 2Fire: escape routes, separation and smoke alarms.
- 3Environment: ventilation, moisture and drainage, including MVHR where used.
- 4Safety: stairs, landings, guarding and glazing.
- 5Noise: sound insulation between rooms and separate dwellings.
- 6Energy: insulation, airtightness and heating, including the New Build Heat Standard.
- 7Sustainability: the sustainability label the home achieves.
The New Build Heat Standard
Scotland's New Build Heat Standard generally requires qualifying new buildings, where the Building Warrant was applied for on or after 1 April 2024, to use climate-friendly main heating systems instead of oil or gas boilers. Amendments effective from January 2025 allow certain bioenergy and peat-burning systems and clarify the treatment of secondary heating. The appropriate solution must be assessed against the Building Standards applicable to the project.
It's one reason heating, insulation and airtightness need to be decided early in design, not left to the warrant stage.

Questions
Do I need a Building Warrant for a new house in Scotland?
Yes. Every new house needs an approved Building Warrant before work starts, and will generally need planning permission too.
Can I put a gas boiler in a new house in Scotland?
Not as the main heating in a new home whose Building Warrant was applied for on or after 1 April 2024. The New Build Heat Standard requires climate-friendly main heating instead of oil or gas boilers; amendments from January 2025 allow certain bioenergy and peat-burning systems and clarify secondary heating. Check the solution against the standards that apply to your project.
What happens if I build without a warrant?
It's an offence, and putting it right costs more: a late warrant is 200% of the standard fee, and a Completion Certificate with no warrant is 300%.
