Conveyancing searches explained: what your solicitor checks (and the gaps you should fill yourself)

Local authority, drainage and water, environmental, flood, coal and chancel searches: what each one actually reveals, what it costs, how long it takes — and the things searches deliberately do not cover that you should check before you offer, not after.


TL;DR


Conveyancing searches are the legal checks your solicitor commissions after your offer is accepted, before you exchange contracts. They are designed to answer a narrow set of questions: is the title clean, who is responsible for the road and drains, is the land contaminated, has it flooded, was it mined. They are thorough on what they cover and silent on everything else.


SearchWhat it revealsTypical costTypical timing
Local Authority (LLC1 + CON29)Planning history, enforcement, building regs, road adoption, conservation/listing, tree orders, nearby road schemes£90–£2502 days–6+ weeks
Drainage & Water (CON29DW)Whether the property connects to mains water and public sewer, water mains crossing the land£40–£905–15 working days
EnvironmentalContaminated-land risk, landfill, flooding, ground stability, energy/infrastructure£40–£701–5 working days
Flood (detailed)Property-level river, surface, coastal and groundwater flood modelling£20–£701–5 working days
Coal Mining (CON29M)Past/present/future mining, shafts, subsidence claims£30–£601–5 working days
Chancel repairLiability to contribute to parish church chancel repairs£10–£30 (often via indemnity)Instant–few days

Searches usually cost £250–£500 in total and are the slowest non-mortgage part of a purchase. Critically, they happen after you have offered and instructed a solicitor — by which point you are emotionally and financially committed. The questions that should shape *whether and how much you offer* — broadband speed, crime patterns, real school catchments, day-to-day flood context, what nearby homes actually sold for — are mostly not in the legal searches at all. That is the gap this guide is about. You can pull most of them in one £14.95 report before you offer.


What searches are for — and when they happen


The purpose of a search is legal protection, not buyer education. Your solicitor (and your mortgage lender) needs to know that the title is good, that the property has the legal rights it needs to function — access, drainage, water — and that there is no known liability or hazard that would make the lender's security worthless. Most lenders will not release funds without a satisfactory local authority and drainage search.


Searches protect the transaction, and protect the lender. They are not designed to tell you whether you'll like living there, whether the broadband is usable, or whether you're paying £30,000 over the odds. Those are your problems to solve, ideally before you commit.


The Local Authority search (LLC1 + CON29)


This is the big one, and the slowest. LLC1 (the Local Land Charges register) lists charges and restrictions registered against the property: financial charges, planning conditions, tree preservation orders, conservation-area status, listed-building status. CON29 is a set of standard questions answered by the council, covering planning permissions and refusals affecting the property, building regulations completion certificates, whether the road fronting the property is publicly maintained (adopted), enforcement notices, and proposals for new roads within 200 metres.


Timing is the headache. Some councils return CON29 results in 48 hours; others, chronically under-resourced, take six weeks or more. This single search is the most common reason a "ready to exchange" purchase stalls.


Drainage and water (CON29DW)


Commissioned from the regional water company, this confirms whether the property is connected to the public water main, whether foul water is connected to the public sewer, and whether any public sewers or water mains cross the land. A public sewer running under the back garden can block where you're allowed to build an extension.


The environmental search


A desktop report compiled from public datasets that pulls together contaminated-land risk — historic industrial use, old landfill, petrol stations — alongside flood screening, ground stability and radon potential. Under Part 2A of the Environmental Protection Act 1990, a current owner can in principle inherit liability for remediating contaminated land, so a "further action" result triggers a follow-up assessment or an indemnity. The flood screen here is area-level; the underlying data largely comes from the Environment Agency, DEFRA and the British Geological Survey.


The optional searches: flood, coal, chancel


Flood (detailed). Where the environmental screen flags risk, solicitors order a dedicated property-level flood report built on Environment Agency modelling. It matters for insurability and price — properties in higher flood-risk bands can face steep premiums, partly mitigated by Flood Re for eligible homes built before 2009.


Coal mining (CON29M). Ordered automatically when the postcode falls within a former coalfield. Relevant across large parts of the Midlands, the North, South Wales and central Scotland — and easy to forget where you wouldn't expect it.


Chancel repair. A medieval liability, usually dealt with by a cheap one-off indemnity policy rather than a full search.


What searches do NOT cover


Here is the honest part. There's a large category of things that materially affect whether a home is right for you — and what it's worth — that legal searches simply do not address.


Question that matters to a buyerIn the legal searches?Where it actually lives
Will my broadband / mobile signal be usable?NoOfcom Connected Nations data
What's the crime pattern on this street?NoPolice.uk street-level crime
Which schools can I realistically get into?No (planning only)Ofsted / GIAS + admissions data
Did this street flood last winter, day to day?Partly (area screen)Environment Agency maps, local context
What did nearby homes actually sell for?NoHM Land Registry Price Paid
Is the EPC poor and the bills high?NoEPC Register (MHCLG)
What's the radon risk here?Sometimes (env. screen)UKHSA radon indicative atlas
How deprived / what's the area trajectory?NoONS Census 2021, IMD 2025
Council tax band and likely billSometimes (CON29 partial)VOA council tax bands
Heavy-traffic or accident hotspot nearby?NoDfT STATS19 road safety data

The problem is timing. By the time searches run, you've offered, paid for a survey, instructed a solicitor and told everyone you're moving. If the broadband turns out to be 8 Mbps, or three near-identical homes sold for £25k less last quarter, you find out too late to act cleanly on it.


Do this before you offer, not after


The fix is to front-load the questions searches won't answer. Almost all of it is public and free at source:


+Broadband and mobile — Ofcom's Connected Nations dataset gives real available speeds.
+Crime — Police.uk street-level crime by month; look at the pattern over a year.
+Schools — Ofsted ratings via GIAS, cross-checked against last year's *actual* admission distances.
+Flooding in plain terms — the Environment Agency's long-term flood-risk service.
+Recent sales — HM Land Registry Price Paid; your strongest negotiating evidence, and it predates any search.
+EPC and likely bills — the EPC Register (MHCLG).
+Radon — the UKHSA indicative atlas.
+Deprivation and area context — ONS Census 2021 and the IMD 2025.
+Council tax — the VOA band list, which feeds your cost-of-living picture.

Pulling these together by hand means seven or eight government portals and a spreadsheet. That's what our £14.95 property report automates: one PDF, every source cited with a retrieval date, for any English or Welsh address before you offer. It's a one-off £14.95 — no subscription — and it is explicitly not a replacement for legal searches or a survey. You can also start free: search an area to see the postcode picture, then pay only when you're serious about a specific address.


Honest caveats


+Coverage is England and Wales for the title, Land Registry Price Paid and the EPC Register. Scotland runs on the Home Report and a different conveyancing process; Northern Ireland is separate.
+Searches still matter. Nothing here replaces the local authority, drainage and environmental searches your solicitor runs, or the lender's requirement for them.
+Public data has lag. Police.uk crime is reported monthly with a delay; an EPC can be up to ten years stale. Read the dates.
+A search result is not a guarantee. It only reports what the council holds. Your solicitor's enquiries and your own eyes still matter.

The pattern to remember is sequence: desk due-diligence before you offer, survey and legal searches after the offer is agreed.
