Schools data included from Starter
Every Starter plan and above includes full access to ~27,000 schools across England — with Ofsted ratings, phase, age range, pupil numbers, and straight-line distance. Data sourced directly from the DfE's GIAS register. Most competitors charge this as a bolt-on or per-lookup fee. We include it.
Explore — property intelligence dashboard
Search any UK area and see every listing event — new instructions, price reductions, sales agreed. Explore uses its own credit system, completely separate from API calls.
API calls ≠ Explore credits. Using the API never consumes Explore credits, and using Explore never consumes API calls. Different products, different billing.
Credit packs
Four modules. All included on every paid plan.
Every paid plan (Starter through Scale) gets access to all four modules — Core Property, Risk & Environment, Market & Pricing, and Planning & Land. Tiers differ only on monthly call quota and rate limit. Most endpoints cost 1 call — premium endpoints use call weights that reflect their real infrastructure cost.
Core Property
All plans
The foundation. Address autocomplete, property records (60+ fields), EPC ratings, council tax band, sold price history.
Endpoints: address/find · address/retrieve · properties · epc-checker · council_tax_band · property_sales
Risk & Environment
All paid plans
All 7 environmental risk types (flood, radon, coal mining, landfill, noise, air quality, invasive plants), deprivation index (IMD 2019), and crime data.
~27,000 schools with Ofsted ratings
Nearby schools by postcode or lat/lng — phase, age range, pupil numbers, distance. Direct from DfE GIAS.
Endpoints: risks/{type} · deprivation · crime · schools/nearby
Market & Pricing
All paid plans
Comparable properties 10 calls, price trends and distributions by outcode, live property listings from Home.co.uk's 30-year dataset, estate agent market share statistics.
Endpoints: comparables · price_trends · price_distributions · live-listings · agent_stats
Planning & Land
All paid plans
National planning applications search, Land Registry title data, geographic boundary lookup, and solar assessment 5 calls (external MCS API). The complete development and land research toolkit.
Endpoints: planning · property_lr_titles · boundaries/autocomplete · solar-assessment
Four call weights — not 65
Most endpoints cost 1 call. Premium endpoints use weighted billing that reflects their real infrastructure cost: address find/postcode 2 calls, address retrieve 5 calls (Royal Mail PAF licensing), Land Registry confirmed sales 5 calls (HMLR licensing), solar assessment 5 calls (external MCS API), comparables 10 calls (PostGIS spatial query). Every response includes an X-Call-Weight header so you always know.

Frequently asked questions
What are API modules?
Modules are groups of related endpoints — a way to describe what the API covers. Every paid plan (Starter through Scale) gets access to all four modules: Core Property, Risk & Environment, Market & Pricing, and Planning & Land. The Free tier gets Core Property only (100 calls/month). Paid tiers differ on monthly call quota and rate limit, not on which endpoints are accessible.
What happens if I exceed my monthly call quota?
API access pauses for the remainder of the billing period. You can upgrade to a higher tier at any time — changes take effect immediately and billing is prorated. Usage warnings fire at 80% and 95% of your quota.
How does call weighting work?
Most endpoints cost 1 call. Five endpoint groups cost more because of real infrastructure costs: address find & postcode (2 calls — search licensing), address retrieve (5 calls — Royal Mail PAF + OS licensing), Land Registry confirmed sales /lr_sales/ (5 calls — HMLR licensing), solar assessment (5 calls — external MCS API), and comparables (10 calls — PostGIS spatial queries). Every response includes an X-Call-Weight header so you always know the cost.
What happens if I exceed my monthly limit?
API access pauses for the remainder of the billing period. You can upgrade to a higher tier at any time — changes take effect immediately. We send warnings at 80% and 95% usage.
How do address lookups work?
Address find (autocomplete) and postcode lookup each cost 2 calls (search licensing). Address retrieve returns the full enriched property record and costs 5 calls (Royal Mail PAF + OS licensing). A typical find-then-retrieve workflow costs 7 calls total — still far cheaper than competitors who charge 2–5p per lookup.
Can I change plans at any time?
Yes. Upgrades take effect immediately — your new call quota and rate limit apply right away, and billing is prorated. Downgrades take effect at the start of your next billing period.
Do you cover Scotland?
Currently England and Wales only — 29 million properties. Scotland is on the roadmap but not yet available.
Are Explore credits the same as API calls?
No. Explore credits and API calls are completely separate systems. Your API subscription gives you monthly call quotas for programmatic access. Explore credits are one-time purchases for the browser-based property intelligence dashboard. Using one never affects the other.
How fresh is the transaction data?
Built by the HM Haus Group — a property technology company with deep UK property data. Live listing feeds, Land Registry records, EPC, and environmental datasets in a single API.
What schools data is included?
From Starter (£49/month) upward, you get access to ~27,000 schools across England via the schools/nearby endpoint. Each result includes Ofsted rating, school phase, age range, pupil numbers, capacity, free school meals percentage, head teacher, and straight-line distance. Data sourced directly from the DfE's GIAS register — look up by postcode or lat/lng with a configurable radius up to 10km.
