Firms are ranked by the number of answers that named them, then by how many different questions. The assistants do not give identical answers twice, so a difference of one or two mentions is noise; being named on questions a rival is absent from is not.

The questions we asked

  1. Do I need a plumber or can I fix a dripping tap myself?
  2. How much does it cost to hire a plumber near Guildford for a boiler service?
  3. Is it cheaper to get an annual maintenance contract or just call someone as and when things break?
  4. What's better for an emergency leak, a local independent plumber near Godalming or a big national callout firm?
  5. Should I choose a small independent plumbing firm in Guildford over one of the bigger chains for a bathroom refit?
  6. My boiler's making a banging noise and I live just off the A25 near Bramley, who should I call that isn't a national brand?
  7. We're moving into a new build in Ash and need someone local to check all the plumbing before we settle in, any recommendations?
  8. How do I check if a plumber is Gas Safe registered before letting them into my house near Farnham?
  9. What accreditations should an independent plumber in Surrey actually have to be trustworthy?
  10. Are online reviews for local plumbers around Cranleigh reliable or mostly fake?
  11. Which supplier or plumber should I use for a full central heating system replacement?
  12. Which local plumbing company should I contact for a burst pipe emergency near Guildford?
  13. Which independent plumber would you recommend between one based near Woking and one nearer Guildford for a bathroom installation?
  14. Which locally recommended plumber near Guildford has the best reputation for reliability and turning up on time?

Is your firm on this list?

Every firm above has a private report: which answers named it, which rivals were named instead, whether its website can be read by the assistants, and the three things that would change the result. We work with one plumber in Guildford, and this index is re-measured every month, so the change is visible here.
