3-phase 22kW EV charger installation in Merthyr Tydfil
22kW 3-phase EV charger installation in Merthyr Tydfil for homes with 3-phase supply and small businesses. DNO liaison, fixed price.
If a previous certificate exists, ev chargers usually starts by checking whether it still reflects reality. Age alone does not condemn an installation. Plenty of older Merthyr Tydfil wiring tests perfectly well; some newer work does not. Around CF47–CF48 it is the single most common reason a job runs long. The practical question on this job is confirm 3-phase is present (or quote for upgrade), and it is answered by testing rather than by opinion. In Merthyr Tydfil that usually decides both the scope and the sequence of the visit. For stone-built valley terraces in Heolgerrig and Cefn Coed that detail matters more than it does elsewhere. Ev chargers is one of the more commonly misquoted jobs, largely because nobody tests before pricing it.

What's different about Merthyr Tydfil
Many Merthyr terraces still carry mid-century VIR rubber cabling that fails an EICR on inspection and needs full rewire — relevant because 3-phase installs land heavier loads on the earthing arrangement and the CU often gets upgraded at the same time. It affects timing more than cost.
In most Merthyr Tydfil cases: most homes in stone-built terraces in Heolgerrig and Cefn Coed, ex-council semis in Gurnos, and newer developments around Pant and Dowlais are single-phase — we verify the supply on the survey before quoting. A 3-phase upgrade from the DNO is possible but costs and timelines vary.
Most homes in stone-built terraces in Heolgerrig and Cefn is straightforward to correct once it has been identified properly.

Common questions
Worth it for one car?
Usually no. Worth it for fleet, two cars or genuine fast-turnaround needs.
How do I know the price will not change?
Because it is set after testing, not before. Extra work is only ever agreed with you first.
Is older wiring automatically a problem?
No. Plenty of older Merthyr Tydfil installations test well. Age is a reason to check, not a verdict.

Always. DNO G99 notification handled for you is easier to understand when you can see it, so we photograph anything hidden.
