Gas Safe Register Website Data Extraction

Web scraping job: complete England list from the Gas Safe Register "Find an engineer" search

We need every Gas Safe registered business in England from the public "Find an engineer" search on the Gas Safe Register website, delivered as one clean, de-duplicated CSV.

We already have about half of England (54 postcode areas, ~29,800 businesses). We need the remaining ~45 postcode areas, mainly London, the South East, South West, East Anglia and the Home Counties (SE, SW, W, WC, KT, CR, GU, RG, OX, MK, BS, EX, PL, SO, PO, CB, CM, CO, IP, NR, ME, TN and others). Re-running the whole of England is also fine.

Known issue: the search caps results at 50 per search, so dense areas get cut off. You'll need to search at a finer level (postcode sector, or several points per district) so nothing is missed.

Fields per business:
- Gas Safe registration number (unique key, de-duplicate on this)
- Business name
- Full address and postcode
- Phone
- Email (where shown)
- Number of engineers
- Sole trader or Ltd
- Region

Deliverables:
1. One CSV covering England, no duplicates
2. A short summary of businesses found per postcode area, so we can check coverage
3. Your script, so we can re-run it later

Please tell us: how you'll handle the 50-result cap, a fixed price, and your timescale. We'll start with a paid test on one dense area (e.g. GU) before awarding the full job.
