For an LED upgrade in Greater London we start by counting fittings and running hours, because payback depends far more on how long lights are on than on the price of the fittings.

What's included

Like-for-like or re-planned layouts so light levels meet BS EN 12464-1

LED lighting upgrades FAQs for Greater London

What energy rules apply to new lighting in Greater London?

Approved Document L sets the efficiency that new lighting in Greater London must meet. We check fittings against it at design stage and keep the evidence for building control.

How are prices set in Greater London?

Our guide prices are adjusted for regional labour costs. After a survey you get a fixed price for the agreed scope.

Can the upgrade be claimed against tax?

Many businesses can claim capital allowances on lighting, for example through the Annual Investment Allowance. Lighting in a building is usually treated as an integral feature, so ask your accountant how it applies to you.

Is it worth replacing fluorescent tubes with LED?

Usually, yes. Common T8 fluorescent tubes were caught by GB ecodesign rules from September 2023 and the mercury exemptions for ordinary T5 and T8 lamps ended in February 2024, so replacements are getting harder to source. LED fittings typically use 30–60% less energy for the same light.
