mirrored to R2). 11 of the 49 named sources that could be read published a usable figure; 38 published none and are recorded as not published, never filled in; 6 could not be read (blocked, dead or unreachable) and count nowhere. The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in GBP (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 229 candidate sentence(s) were refused by a reviewer with the reason recorded. Derivation as chartered: the median, minimum and maximum published price for (a) a one-off annual boiler service, (b) a landlord gas safety certificate for one appliance, (c) each additional appliance and (d) the combined service-plus-certificate visit, across every firm that publishes a figure on its own site; cut by region (London, South East, Midlands, North, Scotland, Wales, Northern Ireland), by fuel (mains gas, LPG, oil) and by commercial model (one-off visit, monthly cover plan, letting-agent package). Two derivations are the ones nobody publishes: the London premium measured from firms' own pages rather than asserted from a cost guide, and the SPREAD between the cheapest advertised 'from' price and the price a two-appliance flat actually attracts on the same firm's price table - £35 to £85 on the reads already taken.
