Picture this: you’ve just drawn up a shiny new proposal for an exciting project and sent the document over to the planning authorities for approval. But they say no. It’s a situation nobody wants to be in, and you can avoid it by getting a lighting impact assessment from DFL.

Lighting impact assessments explained

A lighting impact assessment (or LIA) is a survey of your intended installation site that picks up on the potential negative effects your lighting could have on nearby landscapes, wildlife and residents and explains how your lighting scheme can mitigate against them.

LIAs are an important part of every new exterior lighting design, but they’re especially important if you’re working on an ecologically sensitive area, like Specific Sites of Scientific Interest (SSSIs), Special Areas of Conservation (SACs) and Areas of Outstanding Natural Beauty (AONB). That’s because they’re usually required before you get started with your installation.

Our LIA service covers a lot of things. But typically, we’ll include:

  • Baseline light-level surveys.
  • Desktop studies of your installation site.
  • Drawings and 3D models that visualise lighting impact.
  • Lighting strategies.

Why you can trust DFL

We’re one of the UK’s largest independent lighting consultancies, and we do LIAs day in, day out (they’re kind of our thing!).

Without boring you with the technical details, our experts are clued up on all the latest Institution of Lighting Professionals (ILP) guidelines and industry standards required to get the planning authorities on your side, including:

  • PLG 04 — Guidance on Undertaking Environmental Lighting Impact Assessments.
  • GN 01/21 for the reduction of obtrusive light.
  • GN 08/23 — Bats and Artificial Lighting at Night (this one’s new for 2023!).

Not only this, but we’re also on the ILP committees and often have a say in what’s recommended for other lighting consultancies. Plus, we work very closely with environmental consultants. So, when you use our services, you know you’re in good hands.

Achieving your ideal lighting installation isn’t just about following the rules. It might be cliché, but we know that every project’s unique and will tailor our recommendations to your requirements.

We offer clear, easy-to-understand advice (no product jargon!) and ongoing support, with our team members acting as expert witnesses for planning appeals.

So, it’s up to you. We know it’s a big decision, but you can trust us to get your plans approved...
