Energy Performance Certificates, more commonly known as EPCs, are a legal requirement for most residential properties in Scotland.

If you are building, buying, selling, or developing a new build home in 2026, understanding EPC requirements is essential.

This guide explains whether new build homes in Scotland need an EPC, when it must be issued, how the process works, and how upcoming regulatory changes affect new developments.

What Is an EPC?

An Energy Performance Certificate (EPC) provides an assessment of a property’s energy efficiency and environmental impact. Properties are rated on a scale from A (most energy efficient) to G (least efficient). The certificate also includes estimated energy costs and recommended improvements to reduce energy use and carbon emissions.

In Scotland, EPCs are designed to help buyers, tenants, and owners understand how energy-efficient a home is and how costly it may be to heat and power over time.

Do New Build Homes in Scotland Need an EPC?

Yes. All new build homes in Scotland require an EPC once construction is complete. This requirement applies regardless of whether the property is being sold, rented, or retained by the developer.

An EPC must be produced for a new build property:

When the building work is finished
Before the property is sold or marketed
Before the property is let to tenants
Before the building completion certificate process is finalised

In practical terms, a new home cannot be legally marketed or transferred to an owner without a valid EPC in place.

When Is the EPC Issued for a New Build?

For new build homes, the EPC is issued after construction is completed, rather than during the build phase. The assessment is based on the as-built property, reflecting the actual materials, insulation levels, heating systems, and energy features installed.

Once the EPC assessment has been carried out, the certificate and property report must be made available to the new owner. Under updated Scottish regulations, this is expected to happen shortly after the completion certificate is submitted to the local authority verifier.

How Are EPCs for New Builds Different?

New build EPCs differ from those for older properties in several important ways:

They are based on detailed construction data rather than visual inspection alone
They reflect modern building standards, insulation, and low-carbon technologies
They often achieve higher ratings, commonly A or B
They are closely linked to Building Standards compliance

Because new homes are built to current Scottish Building Standards, they typically perform significantly better than older housing stock.

EPC Regulations in Scotland from 2026

From 31 October 2026, Scotland will introduce updated EPC regulations under the Energy Performance of Buildings (Scotland) Regulations 2025. These reforms modernise the EPC system and apply to both new and existing buildings.

Key changes relevant to new build homes include:

A redesigned EPC format with clearer information
Updated rating metrics that place greater emphasis on energy efficiency and emissions
A reduced EPC validity period, moving from 10 years to 5 years

Although new builds will still require an EPC at completion, developers and owners should be aware that certificates will expire sooner than under previous rules.

Transitional Arrangements for New Builds

There are transitional provisions for properties completed close to the regulatory changeover date.

If a new build home is completed shortly before 31 October 2026, it may be issued with an EPC under the previous regulations. These certificates can remain valid for a limited transitional period, typically up to 31 October 2027, for the purposes of sale or letting.

However, new build homes completed on or after 31 October 2026 are expected to comply fully with the new EPC framework.

Who Is Responsible for Obtaining the EPC?

For new build properties, responsibility usually lies with:

The developer or builder
The party submitting the building completion certificate

The EPC must be arranged using a registered and accredited energy assessor. Once completed, the certificate is lodged on the Scottish EPC Register and provided to the property owner.

What Happens If a New Build Does Not Have an EPC?

Failing to obtain or provide an EPC when required is a breach of Scottish regulations. Local authorities are responsible for enforcement and can issue penalties for non-compliance.

Consequences may include:

Financial penalties
Delays in property sales or handovers
Issues with legal compliance during conveyancing

For developers, missing EPC requirements can also affect reputational trust and slow down transactions.

Do Self-Build Homes Need an EPC?

Yes. Self-build homes in Scotland also require an EPC once construction is complete. Even if the property is not being sold or rented immediately, an EPC is still required as part of the completion process.

If the property is later sold or let, the EPC must still be valid at that time.

Summary

In summary:

All new build homes in Scotland require an EPC once construction is completed
The EPC must be in place before sale, marketing, or letting
Updated EPC regulations take effect from 31 October 2026
EPC validity periods are reducing, meaning renewals will be needed more frequently
Developers and self-builders are responsible for arranging the EPC

Whether you are developing multiple properties or completing a single self-build, ensuring EPC compliance is a vital part of meeting Scotland’s property and energy efficiency regulations in 2026 and beyond.

Frequently Asked Questions

Do newly built homes in Scotland require an EPC certificate?

Yes, new-build homes in Scotland normally require an Energy Performance Certificate before the property can be sold or occupied. The EPC provides information about the home’s energy efficiency and estimated running costs, helping buyers understand the property’s environmental performance.

How are EPC ratings calculated for new-build properties?

New-build homes are typically assessed using the SAP methodology rather than RdSAP. SAP calculations use detailed construction and design information, including insulation levels, heating systems, ventilation, glazing, and renewable energy features, to produce an EPC rating.

Do new-build homes usually achieve higher EPC ratings than older properties?

Many new-build homes achieve stronger EPC ratings because they are constructed to modern energy efficiency standards. Features such as improved insulation, energy efficient windows, low-carbon heating systems, and better airtightness can all contribute to higher EPC scores.

Can a new-build property receive a poor EPC rating?

While uncommon, a new-build home could receive a lower-than-expected EPC rating if certain energy efficiency features are limited or if the property’s heating and insulation performance do not score as highly as similar developments. The final EPC rating depends on the full SAP calculation.

Why is an EPC important when buying a new-build home in Scotland?

An EPC helps buyers compare the energy efficiency of different new-build properties and estimate future heating and electricity costs. A strong EPC rating may also make the property more attractive for resale and could indicate lower carbon emissions and improved overall energy performance.
