In Great Britain, common T8 fluorescent tubes were caught by ecodesign rules from 1 September 2023 and the mercury exemptions for ordinary T5 and T8 lamps ended on 1 February 2024.
Privately rented commercial property in Wales generally needs an EPC of E or better, or a registered exemption, and lighting is one of the cheaper ways to improve a rating.
Dolwyddelan FAQs
Who does the work in Dolwyddelan?
Work is carried out by vetted electricians working under S&K Property Investments and Improvement Ltd, which is responsible for the job and invoices you directly.
Is the price fixed?
Yes. After the survey you get a fixed price for the scope agreed. If you add to the scope later, we price the extra before doing it.
How quickly can you survey in Dolwyddelan?
Most surveys in Dolwyddelan can be booked within a few working days. Tell us about any deadlines, such as a lease end or a fire risk assessment action, and we will try to fit around them.
Do you just change the tubes?
We recommend replacing the whole luminaire. Retrofit LED tubes leave old ballasts and holders in place, which can fail and complicate future maintenance. A complete fitting is cleaner, more efficient and simpler to certify.
