How UK fee estimates are made
Model 1.0.0 is a structured set of launch assumptions. It is not a survey and not a set of quotes collected through AccountantConnector.
Estimates are monthly ranges in pounds from benchmark model 1.0.0.
The model adds the services you select, then applies one complexity band. It does not use the other country's prices, and it does not ask a language model to invent a fee.
A sentence about quotes received through AccountantConnector is allowed only when a comparison cell has at least 30 quotes from at least 5 firms in that market, over 18 months. No cell meets that bar, so every result on the site is labelled a benchmark.
These launch ranges are assumptions maintained in the fee model. They are not HMRC rates, IRS rates, or a published fee survey. Tax calculators stay unavailable until those official rules are verified.
