Garden office electrical installation in Merthyr Tydfil
Garden office electrics in Merthyr Tydfil: SWA supply, sub-board, sockets, lighting and heating. Fully certified to BS 7671.
If you are weighing up at a Merthyr Tydfil address, the useful detail is below rather than in a brochure. We work to the current edition of BS 7671 and note where an older installation departs from it and why that matters. It is one reason we quote after the survey rather than over the phone. Merthyr Tydfil County Borough Council is the authority for Merthyr Tydfil, so where the work is notifiable the registration goes through them. That is checked with instruments, not by eye. Merthyr Tydfil property owners generally want to know two things about outdoor electrics: is it necessary, and what will it involve.
- Sub-board with own RCD protection It is checked before anything is signed.
- Sockets, lighting, heating, data Checked at first fix and again at test.
- Where sockets, lighting, heating, data shows up, we test the neighbouring circuits too.
- Outdoor lighting & security spurs — cheap to confirm with instruments, expensive to assume.
- Fully certified + Part P notified — common enough locally that we carry the parts for it.

Damp ingress and age combine, and most Merthyr Tydfil gardens need 10–25m of SWA buried is the outcome.
Many Merthyr terraces still carry mid-century VIR rubber cabling: visible on inspection, confirmable with a meter.
