Capabilities

Tools 7

area_market

Use when someone asks about typical rents or house prices around a postcode in England. Returns the ONS average monthly private rent for the local authority (with bedroom breakdown and annual change) and the HM Land Registry median sale price and number of sales for the postcode district, from a dated snapshot. Each figure carries its source, release and obtained dates, period and the required attribution. Read-only. Area figures only, never a valuation of one home. Information, not financial advice.

Discovered
check_address

Use when someone asks what applies to a rented home at a postcode in England. Returns whether a council property licence is needed for the household type, the council's licensing schemes, the planned landlord register window, flood zone and conservation area, each with its source, and councilPage, Lettance's page for that council. Read-only. England only; a council we have not researched yet says so instead of guessing. Information, not legal advice.

Discovered
compare_addresses

Use when someone wants to compare 2 to 4 rented homes or areas in England by postcode. Returns each postcode's check_address answer and area market figures, plus a side-by-side table of licence need, landlord register window, flood zone, conservation areas, Article 4 directions, average local rent and median sale price. Every field names its source, licence and dates; anything the sources cannot settle is unknown, never no. Read-only. Each postcode counts as one request against the rate limit. Information, not legal advice.

Discovered
council_licensing

Use when someone asks about a council's licensing schemes in England. Returns every scheme for the council with its wards, dates, fees and council sources. Pass a slug such as 'southwark' or a name such as 'Birmingham'. Read-only. A council we have not researched yet returns researched: false with its region and landlord register window.

Discovered
get_rule

Use when you have a rule id from search_rules and need its full detail: the requirement, deadline, evidence to keep, penalty, legal basis and official guidance links. Read-only. Unknown ids return an error rather than a guess.

Discovered
plan_rental

Use when a landlord in England asks what is due for a rented home and when, or wants a plan or calendar for it. Give the postcode and whatever the landlord knows: every other argument is optional. Returns each duty with its status, date, plain explanation and cited rules for the next 12 months, the questions still worth asking (as argument names), and links to an interactive plan and a calendar file. Statuses rely on the landlord's own answers, not documents. Read-only. Nothing is stored. Information, not legal advice.

Discovered
search_rules

Use for general questions about what private landlords in England must do, such as gas safety, deposits, EPC ratings, smoke alarms or notices. Searches Lettance's catalogue of rules, each cited to legislation.gov.uk or GOV.UK, and returns matching rule ids with summaries. Use get_rule for one rule's full detail. Read-only.
