market analysis.

Property
Identity
address / postcode / uprn
Full UK address, Royal Mail postcode (e.g. W11 2EF), and
UPRN (Unique Property Reference Number) from Ordnance Survey — the definitive UK property identifier
used by Land Registry, local authorities, and mortgage lenders for every property in England, Scotland,
Wales, and Northern Ireland.
"postcode": "W11 2EF", "uprn": "10023492817"
Property
Identity
property_type / listing_type
Property type using UK taxonomy (Detached,
Semi-Detached, Terraced, Flat/Apartment, Maisonette, Bungalow, Cottage, Studio, HMO) and listing type

portals.
"type": "Terraced", "listing": "For Sale"
Property
Identity
tenure / lease_years_remaining
Freehold or Leasehold tenure — a uniquely UK property
data field with profound valuation implications. For leasehold properties, years remaining on the lease
is captured, as sub-80-year leases trigger significant valuation discounts and mortgage lending
restrictions under UK law.
"tenure": "Leasehold", "lease_remaining": 74
Property
Identity
geo_coordinates / local_authority
Verified lat/lng with sub-50m accuracy plus local
authority / council name for the property. Local authority determines planning rules, council tax rates,
and permitted development rights — essential for development appraisals and planning intelligence
applications.

Property
Identity
images[] / floorplan_url / virtual_tour
All listing photo URLs, floorplan image URL, and virtual
tour link where available. Floorplan availability is a particularly significant UK listing quality
signal — properties with floorplans sell faster and at higher prices, making this field valuable for
listing quality scoring models.
"has_floorplan": true, "image_count": 22
Pricing
price_gbp / price_per_sqft_gbp
Current asking price and price per square foot in GBP —
the core fields of every UK real estate data intelligence workflow. Tracked across Rightmove, Zoopla,
and OnTheMarket simultaneously, timestamped to the minute, and cross-referenced against Land Registry
sold price evidence for the same postcode sector.
"price_gbp": 2850000, "per_sqft": 1347
Pricing
price_history_gbp / price_reduced
Full GBP price change history with timestamps and the
original asking price, plus a boolean reduction flag. UK price reduction signals are particularly
actionable — a property reducing price after 30+ days on market is a motivated seller signal that drives
offer timing in buy-to-let, auction, and residential investment strategies.
[{"date":"2025-04-10","price_gbp":2995000}]
Pricing
stamp_duty_gbp / stamp_duty_breakdown
Calculated stamp duty land tax (SDLT) for England &
Wales or Land & Buildings Transaction Tax (LBTT) for Scotland, including first-time buyer relief,
additional dwelling surcharge (3%), and non-UK resident surcharge (2%) where applicable — a UK-specific
cost field critical for buyer affordability calculations.
"stamp_duty_gbp": 228750, "add_surcharge": true
Pricing
land_registry_sold_price / sold_date
Most recent Land Registry recorded sale price and
transaction date from HM Land Registry Title Register data. The definitive UK property transaction
record — cross-referenced against current asking prices to calculate the seller's equity position and
capital gain since purchase.

Pricing
days_on_market / first_listed_date

correctness and seller motivation.
"dom": 8, "first_listed": "2025-05-27"
Property
Features
bedrooms / bathrooms / reception_rooms
Bedroom count, bathroom count, and number of reception
rooms — a UK-specific field (living room, dining room, study counted separately) not used in US property
data. All three fields are primary comp-filtering dimensions in UK residential valuation and rental
assessment.
"beds": 4, "baths": 3, "reception": 2
Property
Features
floor_area_sqft / floor_area_sqm
Floor area in both square feet and square metres as
measured to RICS standards where disclosed. UK property floor areas are increasingly disclosed on
Rightmove and Zoopla following industry pressure — essential for price-per-square-foot comparisons and
rental value benchmarking.

Property
Features
garden / parking / garage / outbuildings
Garden type (rear, front, both, roof terrace, communal),
parking (off-street, allocated, permit zone, garage), and outbuilding presence. Garden and private
parking are premium value drivers in dense UK urban markets — a property with private parking in Zone 2
London commands a 5–10% premium in any automated valuation model.
{"garden": "rear", "parking": "off-street"}
Property
Features
service_charge_annual / ground_rent_annual
Annual service charge and ground rent for leasehold
properties — UK-specific recurring costs that can materially affect investment returns and mortgage
eligibility. The Leasehold Reform Act 2022 capped ground rent at zero for new leases, making historical
vs. post-2022 ground rent data a compliance intelligence field.
"service_charge": 4200, "ground_rent": 0
Compliance
& Regulatory
epc_rating / epc_score / epc_expiry
Energy Performance Certificate rating (A–G), numeric EPC
score (1–100), and certificate expiry date from the MHCLG EPC Open Data register. EPC ratings are
mandatory for all UK sales and lettings — and from 2025 properties rated below E cannot be let, making
EPC data a critical compliance and investment risk field.
"epc_rating": "C", "epc_score": 72, "expires":
"2034-03-15"
Compliance
& Regulatory
council_tax_band / council_tax_annual_gbp
Council tax band (A–H in England, A–I in Wales) and
estimated annual council tax bill in GBP. Council tax is a recurring ownership cost ranging from £800 to

total cost of ownership calculations.
"band": "H", "annual_gbp": 3847
Compliance
& Regulatory
planning_use_class / listed_building_grade
UK planning use class (C3 Residential, C4 HMO, E
Commercial, etc.) and listed building designation (Grade I, II*, II). Listed building status restricts
permitted development rights and requires listed building consent for alterations — a critical valuation
and development appraisal risk field unique to UK property data.
"use_class": "C3", "listed_grade": "II"

Market
Intelligence
inventory_count_postcode / avg_dom_sector
Active listing count and average days on market for the
property's postcode sector and property type. Sub-30 DOM in a postcode sector signals a strong seller's

requires live scraping to generate.
"active_listings": 42, "avg_dom": 28
Market
Intelligence
asking_to_sold_ratio / sstc_rate
Ratio of Land Registry achieved prices to current asking
prices for comparable sold properties in the same postcode district. SSTC (Sold Subject to Contract)

Rental
Intelligence
rent_estimate_pcm / gross_rental_yield
Market rent estimate in GBP per calendar month (PCM)
derived from comparable active rental listings on Rightmove and Zoopla, and our proprietary rental comp

Net rental yield after estimated management fees
(10–15%), maintenance reserves, void periods, and service charge costs. Buy-to-let ROI estimate
incorporating stamp duty surcharge, mortgage interest relief cap (Section 24), and letting agent fees.

Intelligence
rental_comps_pcm / local_vacancy_rate
Array of comparable active rental listings within 0.25

Brokerage
listing_agent / branch / contact
Listing agent name, estate agency branch name and
address, phone number, and email. This agent contact data is the primary lead intelligence field for UK
mortgage brokers, conveyancers, survey firms, and removal companies targeting active listing agents by
postcode and property type.
"agent": "James Whitfield", "agency": "Strutt &
Parker"
Agent &
Brokerage
agent_active_listings / agent_sstc_rate
Count of the listing agent's currently active UK
listings and their SSTC conversion rate — the percentage of their listings going Sold Subject to
Contract within 60 days. Agent performance metrics enable ranking and scoring of agents by market
effectiveness across every UK postcode district.

Ownership
& Title Intelligence
title_number / title_type
HM Land Registry title number and title
type (Freehold, Leasehold, Commonhold, Flying Freehold). Title data provides the legally
registered ownership structure of the property and is fundamental to conveyancing, lending,

Ownership
& Title Intelligence
owner_occupier_probability /
corporate_owner
Probabilistic classification of whether
the property is owner-occupied, buy-to-let, or institutionally owned, plus identification
of corporate ownership structures where applicable. Corporate ownership intelligence is
particularly valuable for acquisition targeting, portfolio analysis, off-market sourcing,
and landlord concentration studies.
"owner_occ_prob": 0.82,
"corporate_owner": false
Development/Planning Intelligence
nearby_planning_applications /
development_pipeline
Recent planning applications and approved
developments within a defined radius of the property, including residential units,
