How UK fee estimates are made
A monthly range built from the services a business needs. These are launch assumptions, not a survey of quotes and not an HMRC rate.
The current assumption set is labelled model 1.0.0. Each estimate is a monthly range in pounds. It adds the services you select, then applies one adjustment if the work is more complex.
UK prices are never used to answer a US question, or the reverse.
We will describe a figure as quotes received through AccountantConnector only after a comparison has at least 30 quotes from at least 5 firms in that market, over 18 months. No comparison meets that bar, so every result is an indicative benchmark.
These ranges are maintained assumptions. They are not HMRC rates, IRS rates, or a published fee survey. Tax calculators stay unavailable until those official rules are verified.
