Planning and design evidence

Planning energy and sustainability statements

Connect the site’s planning requirements to a clear energy strategy, calculations and deliverable design commitments.

When you need this work

A useful energy statement is more than standard wording. It should show which policies apply, what has been tested and how the proposed design responds.

We review the planning context and agree the evidence needed for the application or condition. The statement can draw together demand reduction, fabric, services, low-carbon technologies and relevant calculation outputs. Local policy varies and can change, so the scope is based on the site and submission date rather than a generic template.

What we check

Policy-led scope

We identify the adopted policy, guidance and validation requirements relevant to the site. Where interpretation is uncertain, the project team can seek confirmation from the planning authority.

Evidence behind the narrative

Claims are linked to drawings, specifications or calculations. Options that were not selected are not presented as commitments.

A strategy the team can carry forward

The final statement distinguishes firm design measures from matters that still need development, helping later teams avoid drifting away from the consented approach.

Common coordination issue

Planning evidence and Building Regulations reporting serve different purposes. Keep the policy baseline, targets and committed measures visible so later specification changes can be checked against the consented strategy.

What you receive

Energy statement

A structured report addressing the agreed policy and project requirements.

Calculation evidence

Relevant modelling summaries or schedules where included in the scope.

Action list

Outstanding evidence or design commitments that must be resolved before submission or condition discharge.

Getting started

What we need

Planning context

Site address, authority, application stage, relevant policy correspondence and planning requirements.

Design information

Drawings, area schedule, fabric and services strategy, energy models and sustainability information.

Options and constraints

Technologies considered, site limitations, viability information supplied by the project team and any client targets.

Discuss an energy statement

Before commissioning

Can you use the same statement for any local authority?

No. Policy, evidence and terminology vary by location and project type.

Is an energy statement a Part L calculation?

No. It may use Part L modelling as evidence, but planning policy and Building Regulations are separate controls.

When should the statement start?

Early enough to influence the architecture and services strategy, not after the design has been fixed.

Sources and further reading

Use the edition, jurisdiction and assessment route that apply to the project. Publication of newer guidance does not automatically change an existing project’s requirements.

Scope the statement around the actual site

Send the site address, planning stage, policy comments and current design information.
