Commercial lighting design FAQs for Dyfed
What energy rules apply to new lighting in Dyfed?
The Welsh Approved Document L sets the efficiency that new lighting in Dyfed must meet. We check fittings against it at design stage and keep the evidence for building control.
How are prices set in Dyfed?
Our guide prices are adjusted for regional labour costs. After a survey you get a fixed price for the agreed scope.
Do I need a lighting design for an LED upgrade?
For a like-for-like swap in a simple office, a survey is often enough. For new layouts, warehouses, sports areas or where light levels are disputed, a calculated design avoids getting it wrong.
Can you design and install?
Yes. Most clients ask us to design and install so one team is responsible for the result.
