A Simpler Building Regulations Route for Certain Projects
A Building Notice is an alternative Building Regulations route for some types of building work in England.
Unlike a Full Plans application, detailed plans are not approved in advance. Instead, the project is notified to building control and compliance is checked as the work progresses, with additional information provided if requested.
This can make the process quicker to start, but it also means more technical responsibility sits with the project team during construction.
Tholos can help assess whether a Building Notice is appropriate, prepare the technical information needed for the work and support the project through the building control process.

What Is a Building Notice?
A Building Notice is a Building Regulations application route used for certain types of building work in England.
Instead of submitting a complete set of detailed plans for formal approval before construction, the relevant building control body is notified that the work is going to take place.
Building control then inspects the work as it progresses and may request drawings, structural calculations or other technical information where necessary.
This route is generally more suitable for simpler projects where the construction is straightforward and the technical issues are well understood.

Is a Building Notice the Same as Planning Permission?
No.
Planning permission and Building Regulations are completely separate.
A project may not need planning permission but still require Building Regulations approval.
Likewise, a project may have planning permission but still need to comply with Building Regulations.
A Building Notice only relates to the Building Regulations process.

Building Notice vs Full Plans
The main difference is the amount of information reviewed in advance.
With a Full Plans application, detailed drawings and technical information are submitted for assessment before or during the early stages of construction.
With a Building Notice, the project can proceed without formal plan approval in advance, and compliance is checked through inspections and any information requested during the work.
A Building Notice can therefore be faster to begin, but it provides less certainty before construction starts.

When Might a Building Notice Be Suitable?
A Building Notice may be appropriate for relatively straightforward work such as:
- simple internal alterations
- certain structural openings
- some small extensions
- straightforward drainage work
- uncomplicated domestic alterations
It is generally less suitable where the project involves significant complexity or where detailed coordination is needed before construction.
That can include projects with:
- complex structural design
- extensive fire safety requirements
- unusual construction
- major extensions
- complicated loft conversions
- significant drainage work
- listed buildings
- technically sensitive details
What Information Is Needed?
A Building Notice does not usually require the same complete drawing package as a Full Plans application at the outset.
However, that does not mean drawings or technical information are unnecessary.
Building control may still request:
- structural calculations
- construction details
- drainage layouts
- fire safety information
- insulation details
- ventilation information
- architectural drawings
- other technical information
The project still needs to comply with the Building Regulations whether or not the information was approved in advance.
Building Notice for Extensions
For a simple extension, a Building Notice may sometimes be considered.
However, an extension still needs to comply with requirements relating to:
- foundations
- structure
- insulation
- drainage
- ventilation
- fire safety
- glazing
- roof construction
- connection to the existing building
If those details are not resolved before work starts, decisions may have to be made during construction.
That can increase the risk of delays or changes on site.
Building Notice for Loft Conversions
Loft conversions are often technically complex.
They commonly involve:
- structural floor design
- steel beams
- stairs
- fire protection
- smoke detection
- dormer construction
- insulation
- ventilation
- roof alterations
Because these elements interact closely, a more detailed Full Plans approach is often easier to manage than relying on a Building Notice.
Building Notice for Structural Alterations
Some relatively simple structural alterations may be suitable for a Building Notice.
Examples can include:
- removing a load-bearing wall
- creating a new opening
- installing a beam
- altering a floor structure
Structural calculations are still normally required.
The fact that a Building Notice is being used does not remove the need for proper structural design.

Structural Design
Structural design should be developed properly even on projects using a Building Notice.
This may involve:
- beams
- columns
- foundations
- floor structures
- roof supports
- connections
- stability
Poorly resolved structural work can create both safety and compliance problems
Drainage Design
Drainage can still be a significant part of Building Regulations compliance.
Where drainage is being altered or new connections are required, the project may need information showing:
- foul drainage
- surface water drainage
- inspection chambers
- connection points
- rainwater disposal
This should be resolved before the relevant work is covered over.
Fire Safety Design
Fire safety remains important regardless of the application route.
The project may need to consider:
- escape routes
- fire doors
- smoke detection
- protected stairs
- fire separation
- structural fire protection
More complex fire safety requirements can make a Full Plans application more appropriate.

Can Work Start Quickly With a Building Notice?
Potentially, yes.
One of the main attractions of the Building Notice route is that there is no need to wait for detailed plans to be formally approved before construction starts.
However, this does not mean the project should begin without proper technical preparation.
If building control later identifies non-compliant work, changes may be required.
That can be much more expensive once construction is underway.
Building Control Inspections
Site inspections are central to the Building Notice process.
Building control may inspect stages such as:
- excavation
- foundations
- drainage
- structural work
- insulation
- roof construction
- fire protection
- completion
The exact inspection stages depend on the project.
Some work must be inspected before it is covered up.
What Happens If Building Control Asks for More Information?
That is normal.
The inspector may request:
- calculations
- additional drawings
- revised details
- product information
- clarification of construction methods
This information must then be provided so that the work can be assessed properly.
A Building Notice should not be treated as a way to avoid technical design.
It simply changes when that information is reviewed.

Risks of Using a Building Notice
The main risk is that there is less certainty before construction begins.
Potential issues include:
- technical problems being identified late
- redesign during construction
- additional cost
- delays
- work needing to be altered
- builders making assumptions
For very simple projects, this may be manageable.
For larger or more complicated work, the additional certainty of Full Plans is often valuable.
Building Notice and Builder Pricing
A Building Notice may be acceptable for regulatory purposes, but builders still need clear information to price the project properly.
If they are given only basic drawings, quotations may contain:
- assumptions
- exclusions
- provisional sums
- inconsistent interpretations
Technical drawings can therefore still be important even if the Building Notice route is used.
Technical Drawings Are Still Useful
Even if formal Full Plans approval is not required, technical drawings can help reduce uncertainty.
They may show:
- construction build-ups
- dimensions
- junctions
- structural coordination
- insulation
- drainage
- materials
This can help both the builder and building control understand the intended work.
building notice
Completion Certificate
Once the work is finished and building control is satisfied that it complies with the Building Regulations, a completion certificate can normally be issued.
This is important documentation and should be retained.
It may later be requested during:
- property sales
- remortgaging
- legal checks
- future alterations

Building Notice and Principal Designer Duties
The Building Regulations dutyholder requirements still apply regardless of whether the project uses Full Plans or Building Notice.
Design work needs to be properly coordinated, and where applicable a Principal Designer may need to manage Building Regulations design duties.
It may later be requested during:

When Is a Building Notice Not Appropriate?
A Building Notice is not suitable for every project.
The correct application route depends on the nature of the work and applicable regulations.
More complex, higher-risk or technically demanding projects may require a different route or substantially more detailed approval before work starts.
For domestic clients, the safest approach is to establish the regulatory route before construction begins rather than choosing Building Notice simply because it appears quicker.
Building Notice Applies to England
The Building Notice route described here relates to the Building Regulations system in England.
Scotland uses a different building standards system based on Building Warrants.
Other parts of the UK also have their own procedures.
The correct local process should therefore be confirmed before preparing the application.

Already Have a Builder Ready to Start?
If a builder is ready but the technical design is still incomplete, it is worth checking whether a Building Notice genuinely makes sense or whether the project would benefit from further design work first.
Starting quickly is not always the same as starting efficiently.
