Last reviewed 6 August 2026.
Standard 4.14 used to be about ducting. It is now about connection, and the change has not been widely noticed.
On 1 January 2025 the Building (Scotland) Amendment Regulations 2024 substituted standard 4.14 in Schedule 5 of the Building (Scotland) Regulations 2004. That was the only thing those regulations did. The title changed from “In-building physical infrastructure for high-speed electronic communications network” to “Gigabit-ready physical infrastructure for electronic communications networks”, and the substance changed with it. Transitional relief expired on 1 July 2025. There is none left.
If your practice standard details or your specification notes were written before 2025, they cite a standard that no longer exists.
What the standard now requires
Every building and building unit must be designed and constructed so that:
- Gigabit-ready in-building physical infrastructure is provided, up to a network termination point.
- A common access point is provided in any building containing more than one building unit.
- So far as is reasonably practicable, gigabit-capable onsite physical infrastructure is provided, and each network termination point is actually connected to it.
The distinction that catches people out is scope. The first two apply to every building, domestic and non-domestic alike. The third, the onsite infrastructure and the duty to connect, applies to dwellings only.
“Gigabit-capable” means a service capable of delivering at least 1000 Mbps.
The Connectivity Plan
The duty to connect is evidenced, not assumed. A connectivity plan is submitted to the verifier with the building warrant application, prepared by the applicant and supported by evidence from at least two suitable network operators engaged for the development. A template is published at Annex 4.A of the Technical Handbook, in five parts: A development details, B a statement of connectivity, C confirmation of the network operator including the agreement reference, D the detail of the connectivity and infrastructure to be installed, and E the concession route where meeting 4.14(c) is not reasonably practicable.
The cap is £2,000 per dwelling, including VAT, and measured after any financial contribution from the network operator has been deducted. It covers the direct cost of providing the connection from the network distribution point to the network termination point. It expressly excludes the cost of installing the gigabit-ready infrastructure itself, whether in-building or onsite, the administrative costs of submitting the connectivity plan and the warrant fee, and the end-user’s own cost of taking a service.
Where gigabit cannot be delivered, the requirement steps down: gigabit first, then a high-speed connection above 30 Mbps, then a USO-standard connection at 10 Mbps, then no connection. Each step down has to be evidenced, and Part D is explicit about how: quotations from at least two suitable network operators showing that the better connection would exceed the cost cap or is simply not available at the site.
The practical consequence is a programme one, and it is why this belongs at RIBA Stage 2 rather than Stage 4. Engaging operators and obtaining quotations takes time. A warrant application assembled in the week it is due will not have them.
What the guidance adds, and what gets missed
The mandatory standard is short. The guidance under it is where the buildable detail sits, and four points are routinely missed:
- At least one network termination point should be provided in a suitable position within each dwelling.
- A fixed electrical supply must be provided close to the network termination point, for it and its associated distribution equipment, installed in accordance with Standard 4.5 Electrical safety and Standard 4.6 Electrical fixtures. This is the one most often forgotten, and it is a socket that has to appear on an electrical drawing at Stage 4.
- Horizontal ductwork through external walls should be angled downward from the network termination point to the access point, to prevent water ingress.
- Onsite physical infrastructure is required where a wired network can be provided within three years of building warrant approval. Where the distribution point is not yet in place, infrastructure should extend to the likely future location agreed with the operator.
A wireless connection, including fixed wireless access or satellite, is a recognised route where a wired one is not practicable. Where a wireless connection is provided, onsite physical infrastructure need not be. In-building gigabit-ready infrastructure is still required in every case, including where no connection at all can be delivered.
Exemptions
The standard does not apply to alterations or extensions that are not major renovation works, or to buildings under 30 m² that are ancillary to and within the curtilage of a dwelling.
Conversions are treated differently. They fall under Schedule 6, so the test becomes compliance in so far as is reasonably practicable, and in no case worse than before the conversion. A material change of use creating new dwellings is in scope.
Scotland is not England, and the difference costs money
England requires gigabit-ready infrastructure in dwellings under Approved Document R, requirements RA1 and RA2, in force since 26 December 2022, with the same £2,000 cap. Non-dwellings in England remain on the older high-speed standard under R1.
Scotland does not make that split for the first two duties. Gigabit-ready in-building infrastructure and, where relevant, a common access point are required in non-domestic buildings too.
A practice carrying English habits north will under-provide on a Scottish commercial project. It is a small paragraph in the regulations and an expensive one to miss.
The drawing note, corrected
The note in common circulation cites the superseded standard. Anyone still using it is specifying to a regulation replaced in January 2025. This is the corrected version:
CONTRACTOR TO ENSURE THAT GIGABIT-READY IN-BUILDING PHYSICAL INFRASTRUCTURE IS PROVIDED TO A NETWORK TERMINATION POINT WITHIN EACH DWELLING, AND THAT A COMMON ACCESS POINT IS PROVIDED WHERE THE BUILDING CONTAINS MORE THAN ONE BUILDING UNIT, IN ACCORDANCE WITH BUILDING (SCOTLAND) REGULATIONS 2004 SCHEDULE 5 STANDARD 4.14 AS SUBSTITUTED BY SSI 2024/247. WHERE THE BUILDING IS DOMESTIC, GIGABIT-CAPABLE ONSITE PHYSICAL INFRASTRUCTURE IS TO BE PROVIDED AND EACH NETWORK TERMINATION POINT CONNECTED, SO FAR AS IS REASONABLY PRACTICABLE. A CONNECTIVITY PLAN PER ANNEX 4.A OF THE BUILDING STANDARDS TECHNICAL HANDBOOK, PARTS A TO E AS APPLICABLE, IS TO ACCOMPANY THE BUILDING WARRANT APPLICATION. CONTRACTOR TO LIAISE WITH THE TECHNOLOGY DESIGNER AND NETWORK OPERATORS BEFORE COMMENCEMENT.
Copy it, amend it to suit the project, and check it against the current Technical Handbook before it goes on a drawing. It is offered as a starting point, not as advice on a particular building.
The minimum is a floor, not a specification
Standard 4.14 secures one connected network termination point in a dwelling. That is a regulatory floor and it was never intended as a design.
It says nothing about how the signal travels beyond that point: how it reaches the far bedroom, how many cabled positions a wireless network needs, where the equipment lives, how it is cooled, or how it is protected. A house built to 4.14 and nothing else is compliant and, in practice, poorly served.
The Technical Handbook says as much itself. Its guidance invites developers to consider how connectivity can be optimised within a dwelling through the provision of wired distribution between the network termination point and other locations within the dwelling, and points to the NHBC Foundation’s guidance on the connected home. That is the regulator acknowledging that the floor is a floor. The gap above it is where technology design sits.
Common questions
Did Scottish building standard 4.14 change?
Yes. On 1 January 2025 standard 4.14 was substituted by the Building (Scotland) Amendment Regulations 2024. It changed from a high-speed infrastructure standard to a gigabit-ready standard carrying a duty to connect. Transitional relief expired on 1 July 2025.
What is gigabit-ready physical infrastructure?
Physical infrastructure inside a building, such as ducts, containment and cabling routes, capable of carrying a connection delivering at least 1000 Mbps to a network termination point within the building unit.
What is a Connectivity Plan in a Scottish building warrant?
A document submitted to the verifier with the building warrant application, using the template at Annex 4.A of the Building Standards Technical Handbook. It has five parts: A development details, B a statement of connectivity, C confirmation of the network operator, D the detail of connectivity and infrastructure, and E a concession route where 4.14(c) cannot reasonably be met. It must be supported by evidence from at least two suitable network operators.
Does standard 4.14 apply to non-domestic buildings in Scotland?
Partly. The requirements for gigabit-ready in-building infrastructure and for a common access point apply to every building. The requirement to provide onsite infrastructure and connect each network termination point applies to dwellings only.
What happens if a gigabit connection costs more than £2,000 per dwelling?
The requirement steps down. Gigabit first, then a high-speed connection at 30 Mbps, then the Broadband Universal Service Obligation at 10 Mbps, then no connection, with the position evidenced at each stage.
Does standard 4.14 apply to conversions?
Conversions fall under Schedule 6, so the test is compliance in so far as is reasonably practicable and in no case worse than before the conversion. A material change of use creating new dwellings is in scope.
Where a project needs more than the regulatory floor, the technology strategy belongs in the Outline Specification at RIBA Stage 2, not in a variation at Stage 4. We set out how we work with architects and specifiers on our design and consultancy page.
