The 10 Best Electricians in Merthyr Tydfil 2026

Ranked by real customer reviews, listing activity and Companies House registration, from public sources.

How this ranking is calculated

Composite score from public signals:

  • Google Business Profile star rating (when 3+ reviews)
  • Google Business Profile review count (log-scaled)
  • How many public profile links the listing carries: Companies House number, Google Business Profile, other directory profiles the business has supplied, its own website
  • Whether the listing has been claimed by its owner

No business can pay to be listed, and no reviews are fabricated. Placement is influenced by an optional paid Premium subscription, which puts a business ahead of equally-scored rivals here. Premium businesses carry a Premium badge on their own profile page and in our directory listings, but this list does not mark them.
