Scope and evidence

Built around planning, development and compliance decisions.

Use this page to understand when the service is usually needed, what evidence is reviewed and what information helps us quote accurately.

Planning and regulator context
Clear deliverables and next steps
Linked services considered early

EMF assessments consider electromagnetic field constraints where development, infrastructure or sensitive receptors require review.

When this service is used

Used where electromagnetic field exposure, infrastructure proximity or sensitive land uses require a planning or technical review.

Planning and project supportUsed where power infrastructure, substations, transmission equipment or other EMF sources are close enough to a proposed sensitive use to require technical review.

Risk and programme controlEarly screening can establish whether separation and source characteristics make detailed measurement unnecessary or whether site-specific evidence is justified.

What the report normally includes

EMF constraint review
Sensitive receptor context
Planning or infrastructure consideration
Measurement/survey route advice where needed
Clear recommendations for project teams

What we need from you

Providing the right information at the start helps us confirm the scope, quote accurately and avoid back-and-forth once the work is underway.

Site location and proposal
Nearby infrastructure information
Planning comments if available
Site layout
Reason for EMF concern

EMF assessment should start with the actual source and separation distance

Electromagnetic-field constraints depend on the type of electrical or communications infrastructure, its operating characteristics and the location of sensitive receptors within the development.

Consultant carrying out electromagnetic field measurements near electrical infrastructure. — Technical assessment supporting safe and well-informed infrastructure development.

What a robust scope should cover

Identification of relevant EMF sources and infrastructure
Development layout and nearest sensitive receptor locations
Available source, load or operating information
Screening against applicable exposure considerations
Site measurement where desk information is insufficient and measurement is appropriate
Design or separation recommendations where required

What the work should leave you with

A clear record of the source-receptor relationship
Evidence supporting whether detailed assessment is necessary
Measured field information where included in the scope
Practical recommendations for layout or design where needed

Why the detail mattersThe aim is a proportionate assessment based on the actual infrastructure and proposed use, rather than treating every nearby electrical asset as the same level of constraint.

Useful to know before you enquire

Accurate source locations helpPlans showing substations, cables, overhead lines or other infrastructure improve the initial screening.

The proposed receptor mattersResidential, education and other sensitive uses may require a different level of consideration from less sensitive development.

Operating conditions can affect measurementWhere field measurements are used, the source should be understood so the result can be interpreted in context.

Layout can be the simplest mitigationWhere practical, increasing separation can sometimes resolve the issue without complex engineering measures.

FAQ

Common questions

Do I always need an EMF site survey?

No. Some sites can be screened from source information, separation distances and the proposed use. Measurement is used where it is needed to resolve the project question.

What infrastructure can trigger an EMF review?

The relevant sources depend on the project but can include power lines, substations, cables and other electrical or communications infrastructure.

Can layout changes reduce EMF concerns?

Potentially. Increasing separation between the source and a sensitive receptor can be an effective design response where the site allows it.
