What a building warrant is
A building warrant is the council’s approval of building work before it starts. In Scotland the council acts as the verifier under the Building (Scotland) Act 2003. It checks that the proposed work, as drawn and specified, will meet the building regulations. It is separate from planning permission, which asks a different question about whether the work is acceptable on the site.
Section 8 of the Act says a warrant is needed to construct or demolish a building, to provide services, fittings or equipment in or in connection with a building that the regulations apply to, and for any conversion. The Act itself is short and worth reading once.
Which work needs one
The Scottish Government’s homeowner guidance lists the common cases: building a new home, an extension, building or removing load-bearing walls, changing roofs, external walls or other structural elements, converting a loft or garage into a room, and demolition.
West Lothian Council’s own page on the question lists load-bearing walls (timber ones included), attic conversions and garage conversions.
Our pages on loft conversions, garage conversions, home extensions and structural alterations cover the building side of each.
Work that does not need a warrant still has to comply
Schedule 3 of the Building (Scotland) Regulations 2004 lists work that does not need a warrant. The Scottish Government’s procedural handbook is clear that this work must still meet the building regulations.
Some of those exceptions are written for houses and do not extend to flats. If your home is a flat, do not assume a rule you have read about a house applies to it. Ask City of Edinburgh Council, and see the building warrant checker for the questions to take with you.
The order things happen in
- The owner, or an agent acting for them, applies to the council through the national eBuilding Standards portal with drawings, a specification and the fee. Your architect or structural engineer can prepare and submit it for you.
- The council assesses the application and may ask for more information.
- The warrant is granted. Building work starts after this, not before.
- The work is built to the approved drawings. Changes during the build can need an amendment to the warrant.
- When the work is finished, the person responsible, usually the owner, submits a completion certificate. See completion certificates.
Starting work that needs a warrant before it is granted is an offence under section 8 of the Act. If that has already happened, see work done without a warrant.
Your council
- City of Edinburgh Council: route, fees, published timescales and what it checks.
- West Lothian Council: the same, with its own wording on appointments and pre-application advice.
- What building warrants cost in 2026: the national fee scale both councils use.
How Sweet Homes can help
The warrant is an application to the council, usually made by your architect or engineer, and we do not arrange it for you. Around it, we help in four places.
- Before you apply. We ask the warrant question in our first reply to any enquiry that touches structure, layout or change of use, because it changes what we can price and when work can begin. On the call we can recommend architects and structural engineers.
- While the council assesses. We will not start work that needs a warrant until it has been granted, and we do not give a start date before then.
- Once it is granted. We price and build from the approved drawings. If something on site means the drawings need to change, we tell your architect or engineer, because that can need an amendment.
- At completion. Our project contract identifies the inspection records, photographs and certificates the scope needs and who supplies them, so they line up with what your professional team submits for the completion certificate.
