Property searches are the investigative core of any UK conveyancing transaction. They typically cost £280-£420 in total, take 3-6 weeks to come back, and surface the issues that no survey or estate agent description ever will — enforcement notices, contaminated land, flood risk, planned road widenings, mining subsidence, chancel obligations. This guide walks through each search, what it reveals, the typical cost, what to do when something flags, and how to keep the search stage from delaying your purchase.

Why your conveyancer runs searches

Searches protect you from buying a property that turns out to have hidden legal, environmental or geological issues. They also protect the mortgage lender — every UK lender requires at least the local and drainage/water searches before releasing funds. Even cash buyers benefit because the cost of a missed issue (an enforcement notice, a flood zone, a decommissioned coal shaft three metres under the garden) can run to tens of thousands of pounds.

Searches are paid for by you, the buyer. Your conveyancer instructs them in the first week and the cost comes out of the upfront payment requested at instruction. See the conveyancing quotes guide for how searches sit inside the wider quote.

The local authority search

What it covers

The local authority search has two parts. The LLC1 (Local Land Charges Register) returns financial charges registered against the property — outstanding council debts, road adoption charges, conservation area listings, tree preservation orders. The CON29 returns planning history, building control records, enforcement notices, road status, contaminated land assessments, and any local council notices served on or near the property.

Cost and timing

Cost in 2026: £150-£250. London boroughs are the most expensive (Westminster ~£280, Tower Hamlets ~£250, Camden ~£235). Rural councils are cheapest — many West Country and Midlands authorities charge £150-£180.

Timing: 2-4 weeks is the modern average. The fastest councils (Bracknell Forest, Wokingham, Kingston) return inside 5 working days. The slowest (Hackney, Lambeth, Birmingham) can take 6-10 weeks. If your purchase is in a slow borough, expect the local search to be the gating factor on the timeline.

What it reveals

• Planning permissions and refusals over the past 10 years
• Building regulations completions and outstanding notices
• Enforcement notices and breach of condition notices
• Adoption status of the road and footpath
• Planned road widenings or new road schemes within 200m
• Conservation area, listed building, Article 4 direction
• Tree preservation orders
• Contaminated land entries
• Compulsory purchase orders
• Smoke control zone status

What to do when it flags

Enforcement notices and unresolved breaches are the most serious red flags. Many can be cleared with retrospective applications or indemnity policies; some require the seller to put the work right before completion. Planning refusals are informational; if you'd planned an extension, the refusal history is a useful early signal. Conservation area and Article 4 designation mean tighter planning controls — informational, not blocking.

The drainage and water search (CON29DW)

What it covers

Issued by your local water company, the CON29DW confirms whether the property is connected to the public foul and surface water drains, the location of the main public sewer (often shown on a small plan), water supply connection details, sewerage rateable value, and any near-property drainage easements.

Cost and timing

Cost: £50-£80. Timing: typically 5-10 working days. The water companies are reliably fast.

What to do when it flags

Common issues: a public sewer running under the property (means the water company can dig up your garden for repairs without permission — usually accepted), surface-water-only drainage to a soakaway not the public drain (means the seller has been charged a reduced sewerage bill — fine), or non-mains drainage (cesspit or septic tank — means you take over responsibility for maintenance). Rare blockers: property not connected at all to public supply (rural areas, private boreholes — adds survey and indemnity work).

The environmental search

What it covers

A desk-based assessment of contaminated land risk, flood risk, ground stability, radon level, energy infrastructure proximity, and historic land use (old industrial, landfill, petroleum). Performed by specialist providers (Landmark, Groundsure, Future Climate Info).

Cost and timing

Cost: £55-£75. Timing: 1-3 working days. Fast and cheap.

What to do when it flags

Flood risk is the most frequent issue. If the property is in flood zone 2 or 3, your mortgage lender will want flood insurance evidence (Flood Re scheme exists to provide it), and the survey may comment further. Contaminated land flags usually trigger an indemnity policy. Radon flags usually mean a £30-£100 radon test post-completion, and possible mitigation later.

Mining searches

When required

Required where the property sits over historic mining activity. Your conveyancer determines this from postcode against Coal Authority maps and BGS mining records. Common mining-search areas include South Wales, the North East, West Yorkshire, Nottinghamshire, Lancashire, Staffordshire, Derbyshire, Devon (tin), Cornwall (tin and china clay), Cheshire (brine and salt), and Lincolnshire (limestone).

What it covers

Coal Authority searches reveal whether the property sits above recorded coal workings, shafts within 20m, planned future mining, current subsidence claims, and any reported mining damage. Other mining searches (tin, brine, limestone) cover similar ground for those specific activities.

Cost and timing

Cost: £35-£90 depending on type. Timing: 3-7 working days.

What to do when it flags

Workings under the property usually require an indemnity policy (£25-£100) and the property is mortgageable. Active subsidence claims block most lenders — walk away or renegotiate hard. Shafts within 20m generally need a survey assessment by a chartered structural engineer.

Chancel repair search

What it is

A historic legal obligation derived from medieval church tithes. Some landowners are still legally responsible for contributing to repairs of the chancel of the local parish church. The 2003 Aston Cantlow case (Wallbank vs PCC of Aston Cantlow) confirmed the liability was enforceable — and triggered the modern chancel search.

What it covers

The search checks the Church of England Land Registry records and parish registers to identify whether the property has chancel liability.

Cost and timing

Cost: £15-£25. Timing: 1-2 working days. Usually run as part of the standard pack.

What to do when it flags

Standard practice: take out a chancel repair indemnity policy (£20-£80). Settles the matter for all future owners. Since 2013 chancel liability is meant to be registered against title but the indemnity is still standard belt-and- braces protection.

Optional and supplementary searches

Flood risk report (detailed)

Where the environmental search shows flood risk, a £75-£150 detailed flood report from the Environment Agency or a specialist provider gives proper resolution. Insurance providers may insist on this for properties in zones 2 and 3.

Plansearch / planning history

Goes beyond the standard 10-year planning history in the CON29 to a full lifetime planning record. £30-£60. Useful for older properties.

HS2 / energy infrastructure

If the property is near a planned major project (HS2, Sizewell C, new pylon route), a specific search confirms exact distance and compensation eligibility. £30-£80.

Highways search

Confirms whether the road serving the property is publicly adopted (maintained by the highway authority) or private (maintained at owner cost). The CON29 covers this but a standalone highways search adds precision for properties on private estates. £35-£60.

Search regulation and indemnity policies

When a search throws up an unresolved issue — missing planning, chancel liability, ground contamination — indemnity policies are the standard fix. They are one-time premium policies that pay out if a third party enforces against the issue. Premiums sit between £20 and £400 depending on type. Important: indemnity policies become void if you alert the relevant authority to the issue, so don't apply for retrospective planning after taking out a planning indemnity policy.

Timing the search stage

The local authority search is almost always the timeline pacing factor. Two practical levers:

• Personal local search — third-party provider produces a faster version (3-5 working days) at similar cost. Most lenders now accept these for residential purchases. Check with your conveyancer.
• Order at instruction — your conveyancer should instruct searches in the first 1-3 working days of instruction. If they wait for ID checks or contract receipt first, push them.

For wider timeline management see the how to speed up conveyancing guide and the house purchase timeline calculator.

What searches don't cover

Searches are legal and environmental investigations — not condition surveys. They don't tell you about:

• Structural condition of the property
• Damp, rot, infestation
• Roof state
• Boiler and electrics
• The lease terms (if leasehold — that's the LPE1)
• Neighbour disputes (covered by the seller's TA6)

For those, you need a survey. See the house survey guide.

Search costs in your overall budget

Searches are a small but visible line in the buying budget. Combine with SDLT (from our SDLT calculator), conveyancing legal fees (from the conveyancing fees calculator), Land Registry fee, and survey to get the full picture. The moving costs calculator aggregates them. Total typical cost-to- complete on a £350k purchase: £14,000-£18,000 depending on buyer type — the search pack is roughly 2-3% of that.

Frequently asked questions

What property searches are needed when buying a house?

Local authority, drainage and water, environmental, and chancel repair as standard. Mining where the property is over mining workings. Mortgage lenders require at least the local and drainage searches.

How much do property searches cost?

£280-£420 total in 2026. Local £150-£250, drainage £50-£80, environmental £55-£75, chancel £15-£25, mining £35-£90 where required.

How long do property searches take?

Most return in 3-7 working days; local authority typically 2-4 weeks, sometimes 6+ in busy London boroughs. Personal local searches are faster but not all lenders accept them.

What does a local authority search reveal?

Planning history, building control, enforcement notices, road status, conservation listing, tree preservation orders, contaminated land flags, smoke control status, council notices.

What's an environmental search for?

Checks contaminated land, flood risk, ground stability, radon, energy infrastructure proximity. Flood risk is the most common issue surfaced.

Do I need a mining search?

Yes if the property is in a coal, tin, brine, china clay or limestone-mining area. Your conveyancer determines this from postcode against Coal Authority and BGS records.

What's chancel repair liability?

A historic obligation requiring some landowners to contribute to parish church chancel repairs. A £15-£25 search reveals it; if found, a £20-£80 indemnity policy is standard.

Can I waive property searches?

Cash buyers technically can. No mortgage lender will accept it. The £300-£400 saving isn't worth the legal and environmental risk.
