Expert Glazing, Done Right

We're not a national call centre. We're local glaziers who take pride in every job.

U-Value ≤ 1.6 W/m²K

Scotland currently requires replacement windows to achieve a maximum U-value of 1.6 W/m²K — slightly less stringent than England's 1.4 requirement.

Building Warrant

In Scotland, a Building Warrant may be required for window replacement depending on the scope of work. This replaces the Building Control/FENSA system used in England.

CERTASS Scotland

CERTASS operates in Scotland as a Competent Person Scheme, allowing registered installers to self-certify window installations without a Building Warrant.

Section 6 Compliance

Section 6 of the Scottish Technical Handbook covers energy performance. Requirements are updated periodically — always check the latest version for current U-value targets.

Expert Knowledge

Scottish Building Standards for Glazing

Scotland has its own building standards system, separate from the Building Regulations that apply in England and Wales. The relevant standard for glazing thermal performance is Section 6 (Energy) of the Scottish Building Standards Technical Handbook.

The current requirement for replacement windows in Scotland is a maximum U-value of 1.6 W/m²K for the complete window assembly. This is slightly less stringent than England's 1.4 W/m²K requirement, though future updates may align the standards more closely.

Pane Relief delivers to Scotland:

All our sealed units comfortably exceed Scottish requirements. Our standard double glazed units with Low-E glass and argon fill achieve centre-pane U-values well below 1.6 W/m²K, and our triple glazed units provide even greater thermal performance for Scotland's colder climate.

We deliver nationwide via tracked courier, with specialist glass packaging designed to survive transit. Scottish customers typically receive their units within 5-7 working days of order.

Scotland's colder climate means the energy savings from high-performance glazing are even greater. Upgrading to triple glazing with krypton fill can reduce heat loss by up to 50% compared to standard double glazing — particularly worthwhile for exposed or north-facing windows.

Common Questions

Frequently Asked Questions

Everything you need to know about our double glazing repair and replacement services across the South West.

  • It depends on the scope. Replacing sealed units only (not frames) generally doesn't require a warrant. Replacing entire windows may require one unless done through a Competent Person Scheme like CERTASS Scotland. Check with your local authority for guidance specific to your project.

  • FENSA operates in England and Wales only. In Scotland, the equivalent Competent Person Schemes are CERTASS Scotland and others approved by the Scottish Government. If you're having windows installed, ensure your installer is registered with a Scottish-approved scheme.

  • Yes. We deliver to all UK mainland addresses including Scotland. Units are packaged in specialist glass transit packaging and sent via tracked courier. Delivery typically takes 5-7 working days for Scottish addresses.

  • Triple glazing is particularly beneficial in Scotland due to colder average temperatures and longer heating seasons. The additional upfront cost is offset by greater energy savings. We recommend triple glazing for exposed, north-facing, and higher-altitude properties.
