New-Build House properties are a distinctive part of the Merthyr Tydfil housing mix — stone-built terraces in Heolgerrig and Cefn Coed, ex-council semis in Gurnos, and newer developments around Pant and Dowlais, particularly around Dowlais & Heolgerrig. We work on this stock weekly.
Focus on the utility room or garage, the consumer unit location, and the intended cable route. Usually 15–30 minutes on-site or a short photo set.
