Every Treffynnon agent here comes with a fee, inclusive of VAT, settled before you speak to anyone. Some agents set their own. Where they haven't, AgentSeeker quotes the fee on your behalf. Either way it is what you would pay, and it cannot rise at contract stage.
Every Treffynnon agent is scored on four things we can actually see: their Google rating and how many people left one, how competitive the fee is, how many homes they currently have on the market in your postcode district, and how they rank against the other agents working it.
Achieved price against asking, and average time to sell. They are the two figures that matter most, so we are building them from Land Registry records rather than asking agents to report on themselves. Until then we leave them out, because a number we cannot stand behind is worse than no number.
We never share your contact with Treffynnon agents until you approve the shortlist. No spam calls, no brokered leads. You control when outreach starts.
