What Are Conveyancing Searches? Key Facts
Conveyancing searches are investigations your solicitor conducts during the property buying process to reveal hidden issues that could affect your purchase. Think of them as a comprehensive background check on the property itself. These searches uncover everything from flood risks and contamination to planning restrictions and building works planned for the area. Without them, you could inherit serious problems that destroy your investment’s value or even make the property unmortgageable.
The term “conveyancing searches” covers multiple distinct investigations, each targeting different types of risk. Environmental searches detect contamination or flooding risks, while local authority searches identify listings, conservation areas, or planned building works. Drainage searches examine the sewerage and water supply systems serving the property. Some searches are standard and essential for every purchase. Others are optional but highly recommended depending on the property type and location. Your solicitor will advise which searches apply to your specific situation.
The most important standard search is the local authority search, which consists of two main components. The LLC1 form records local land charges such as listed building status or conservation area designations that could restrict what you can do with the property. The CON 29 form contains general enquiries about planning permissions, road schemes, and environmental issues, plus optional questions you can ask about things like contamination history or flooding. Together, these documents protect you and your mortgage lender by exposing problems that could affect property value or use.
Searches typically take between 5 to 15 working days to complete, though this varies by local authority. You’ll pay somewhere between £100 and £400 for the standard bundle, depending on your location and which optional searches you add. London properties often trigger additional searches due to environmental concerns and historical land use. The cost might feel like an extra expense, but consider it insurance against buying a property with hidden defects that could cost thousands to remedy or, worse, prevent you from selling later.
Pro tip: Request copies of all search results to review before exchange of contracts, then discuss any findings flagged in red or amber with your solicitor to understand exactly what remedies or protections are needed.
Types Of Conveyancing Searches In The UK
Conveyancing searches aren’t one-size-fits-all. The UK conveyancing process involves multiple distinct investigations, each designed to uncover different categories of risk. Your solicitor will recommend a tailored package based on the property’s location, age, and type. Understanding what each search does helps you grasp why your solicitor is asking for these investigations and why they cost what they do.
The local authority search is the foundation of every conveyancing transaction. This comprises two main components: the LLC1 form, which records local land charges like tree protection orders and smoke control zones, and the CON 29 questionnaire subdivided into general and optional questions tailored to the transaction. The general questions cover planning applications, enforcement notices, and highways issues that affect the property. The optional section lets you ask specific questions about things like contamination history, flooding, or nearby developments. For London properties, the optional section becomes particularly valuable because older industrial areas carry higher contamination risks.
Beyond the local authority search, several other investigations serve specific purposes. Environmental searches check for issues like contaminated land or flooding risks, which is especially critical in London given its historical land use and proximity to the Thames. Drainage searches provide detailed information about sewerage and water supply infrastructure serving the property, ensuring the systems are adequate and not subject to shared rights that could cause future disputes. Radon gas risk searches assess exposure levels in certain regions where this naturally occurring radioactive gas poses a health concern. Mining searches become essential if the property sits above former mining areas, though this is less common in London itself.
For leasehold properties, you may encounter additional searches specific to flats and apartments. Conservation area searches flag if the property sits within a protected area where alterations face restrictions. Flood searches are increasingly standard in London, not optional, given the city’s exposure to surface water flooding and river flooding. Some solicitors also recommend search companies’ reports that bundle several investigations together, offering better value than purchasing each search separately. The difference between what’s essential and what’s optional depends partly on your mortgage lender’s requirements. Most lenders insist on environmental and drainage searches as a condition of lending.
- Local authority searches reveal planning restrictions and heritage designations
- Environmental searches detect contamination and flooding risks
- Drainage searches confirm water and sewerage infrastructure
- Radon and mining searches assess geological risks where relevant
- Conservation area searches identify protected designations
- Flood searches evaluate water damage exposure
The cost structure varies considerably. A standard search bundle for a London property typically costs between £250 and £500, depending on which optional searches you include. Specialist searches like mining or radon add £30 to £100 each. Your solicitor will provide a breakdown before proceeding, and most will bundle searches together to save money rather than ordering them individually. Many local authorities process searches within 10 to 15 working days, though some can take longer during peak periods. This timeline matters because searches must be completed before you exchange contracts.
Here’s a structured overview comparing the main types of conveyancing searches and their unique purposes:
| Search Type | Main Purpose | Typical Cost Range | Commonly Needed For |
|---|---|---|---|
| Local Authority | Planning, heritage, highway issues | £100–£150 | All purchases, especially London |
| Environmental | Flooding, contamination risks | £80–£150 | All purchases, higher risk in London |
| Drainage & Water | Water/sewer infrastructure | £60–£100 | All purchases |
| Flood | Surface, river flood risk | £40–£80 | London, riverside, lowland areas |
| Mining or Radon | Subsurface/geological risks | £30–£100 | Ex-mining regions, some rural |
| Conservation Area | Protected status & restrictions | £30–£60 | Historic or central locations |
| Leasehold-specific | Management/landlord issues | £50–£150 | Flats/apartments |
Pro tip: Ask your solicitor which searches are mandatory for your property and which are optional recommendations, then clarify whether your mortgage lender has imposed any additional search requirements before committing to the full package.
Who Conducts Searches And When They’re Needed
Your solicitor or conveyancer orders and manages all the searches on your behalf. These are licensed professionals who understand which investigations apply to your specific property and when to request them. You won’t be ordering searches directly or dealing with local authorities yourself. Your conveyancer acts as the intermediary, liaising with search companies, local councils, and environmental agencies to gather the information needed before you proceed to exchange of contracts. This coordination is one of the key reasons you need qualified legal representation during property purchase.
Licensed conveyancers and solicitors order searches early in the conveyancing process once the sale is agreed, to uncover any legal or environmental issues with the property. The timing is deliberate and strategic. Your conveyancer won’t delay ordering searches because the timeline works against you. Most local authorities take between 10 and 15 working days to return completed searches, and some take longer during busy periods. If searches are delayed, it pushes back your exchange date and completion date, potentially affecting your moving date and any dependent transactions like your mortgage completion.
The typical sequence works like this. Your offer on the property is accepted, and you instruct your solicitor or conveyancer. Within days, they begin the search process. They’ll order the standard local authority search first, along with environmental and drainage searches, and any additional searches your mortgage lender requires. Simultaneously, they’ll conduct other investigations like searches at HM Land Registry to check ownership and any registered charges against the property. Your conveyancer coordinates all these searches in parallel rather than waiting for one to complete before starting the next. This parallel approach saves precious time during the conveyancing timeline.
What happens if searches reveal problems depends on the severity. Minor issues like a tree protection order nearby might not affect your decision. More serious problems like flooding risk or contamination require further investigation. Your conveyancer will discuss findings with you in detail before you exchange contracts. This is why the timing of searches matters so much. If searches reveal a major issue late in the process, you could be forced to renegotiate the price or withdraw from the purchase entirely. Getting searches completed early protects you by giving time to investigate, negotiate, or walk away before you’ve committed legally through exchange of contracts.
For leasehold properties, the timeline becomes slightly different because your conveyancer must also obtain the landlord’s consent documents and management company information. Environmental searches still proceed in parallel, but additional time is needed for legal pack documents. Your conveyancer manages all these moving parts. They know which local authorities are slow and which are efficient, which search companies offer the best turnaround times, and which optional searches are genuinely useful versus which are unnecessary for your property type. This expertise protects you from unnecessary costs whilst ensuring you get genuinely important investigations completed.
You should expect your conveyancer to provide you with copies of all search results as they arrive. Don’t be surprised if you receive them in phases rather than all at once. Local authority searches typically arrive first, followed by environmental and drainage searches within a week or so. Your conveyancer will highlight any findings in red or amber that require attention and explain what each one means for your purchase. This transparency means you’re not kept in the dark whilst waiting for completion.
Pro tip: Ask your conveyancer on day one which searches they’ve ordered and request a realistic timeline for when results will arrive, so you can plan ahead and avoid unnecessary stress about delays.
Legal Requirements And Buyer Responsibilities
Conveyancing searches aren’t optional extras you can skip to save money. They’re a legal requirement in most property purchases, particularly when mortgage finance is involved. Your lender won’t release funds without evidence that searches have been completed and reviewed. This means you have a legal obligation to ensure searches happen, and more importantly, to understand what they reveal. This isn’t just about following rules. It’s about protecting yourself from buying a property that carries hidden problems you’ll regret for years.
Your core responsibility as a buyer is to instruct your solicitor or conveyancer to conduct comprehensive searches to reveal burdens or restrictions linked to a property. You’re also responsible for considering these reports carefully as part of your due diligence. This means you can’t simply ignore search results because they’re inconvenient or concerning. If a search reveals that the property sits in a flood risk zone or has contaminated land nearby, you need to decide whether to proceed, renegotiate the price, or withdraw. Ignoring the findings doesn’t make the problem disappear. It only means you’ve knowingly accepted a risk without full information.
Most mortgage lenders impose additional requirements beyond the basic legal standards. Your lender will specify which searches they require as a condition of lending. Typically, this includes local authority searches, environmental searches, and drainage searches. Some lenders demand additional investigations like flood searches or mining searches depending on the property location. If you don’t obtain the searches your lender requires, they can refuse to release your mortgage funds, leaving you unable to complete the purchase. This is why your conveyancer works directly with your lender from the outset to understand their specific requirements and ensure all necessary searches are ordered. Your lender isn’t being difficult. They’re protecting their own investment in the property, which indirectly protects yours.
The legal framework requires that searches such as local authority, environmental, and drainage are completed and reviewed before finalising the purchase. This means you must have search results in hand before you exchange contracts. Exchange of contracts is the point of legal commitment. Once you’ve exchanged, you’re legally bound to complete the purchase even if searches later reveal serious problems. This timeline creates significant pressure to review searches thoroughly and make informed decisions quickly. Your conveyancer manages this timeline carefully, ordering searches early enough that results arrive with sufficient time for investigation before exchange approaches.
What happens if you discover a problem in the searches depends on timing and severity. If you find an issue before exchange, you can renegotiate the price with the seller, ask the seller to remedy the problem, or withdraw from the purchase entirely. If you discover an issue after exchange, you’re bound to complete unless the problem is so severe it makes the property unmortgageable. This is why early review of search results matters so much. Your conveyancer will flag any concerning findings immediately and explain your options. This is where professional advice becomes invaluable. They know which issues are genuinely serious and which are minor technicalities that won’t affect your ability to live in or sell the property.
You also have a responsibility to disclose search findings to your mortgage lender and insurer. Your lender needs to know about any issues before approving the mortgage. Your home insurance provider needs to know about flood risk or previous contamination issues. Failing to disclose these matters could leave you uninsured if a problem occurs. Your conveyancer handles much of this communication on your behalf, but you remain ultimately responsible for ensuring your lender and insurer have complete information.
Pro tip: Don’t just tick boxes on search results your conveyancer sends you. Read the actual findings, ask questions about anything you don’t understand, and discuss the implications before exchange of contracts when you still have negotiating power.
Typical Costs, Risks, And Common Pitfalls
Search costs add up quickly, and many first-time buyers are surprised by the total bill. A standard search package for a London property typically ranges from £300 to £600, depending on which optional searches you include. The local authority search costs around £100 to £150. Environmental searches add £80 to £150. Drainage searches run £60 to £100. Flood searches, increasingly standard in London, cost £40 to £80. Mining and radon searches each add £30 to £60 if your property requires them. These aren’t inflated charges. They’re fees payable to local authorities and specialist search providers to access their databases and compile reports. Your conveyancer doesn’t profit from these costs. They’re genuine disbursements that must be paid regardless of whether your purchase completes.
The real cost of inadequate searches appears later, often too late to do anything about it. Risks include encountering unexpected restrictions, planning issues, or environmental hazards that can delay or jeopardise a purchase. Imagine discovering after completion that the property sits in a flood risk zone and your insurance premiums triple. Or learning that a neighbouring development has planning permission for a 10-storey office block directly overlooking your garden. Or finding out the ground is contaminated and remediation will cost thousands. These aren’t theoretical scenarios. They happen regularly to buyers who skipped optional searches to save money. The cost of not ordering an environmental search (roughly £80 to £150) seems trivial compared to discovering contamination that reduces your property value by £30,000 or makes it unmortgageable.
Common pitfalls often stem from timing and understanding. Insufficient search coverage, late commissioning of searches leading to delays, or misunderstanding search results can leave a buyer exposed to legal or financial problems. Many buyers commission searches too late, leaving insufficient time to investigate findings before exchange. This creates pressure to exchange contracts without fully understanding the implications of search results. Others rely on personal online research or searches conducted by the seller rather than commissioning professional searches. These informal approaches miss critical information that professional searches reveal. Your conveyancer has access to comprehensive databases and expertise to interpret findings. The seller’s information is biased by their desire to complete the sale. Online tools give you incomplete information because they’re based on publicly available data that often lags behind reality.
Another common pitfall involves misinterpreting search results. A property might appear in a contaminated land search because the site was previously industrial, even though remediation occurred decades ago and the land is now safe. Flood search results show risk zones based on historical data, not guarantees that flooding will occur. Conservation area designations mean certain alterations require permission, but they don’t prevent living in the property. Many buyers panic at red or amber flags in searches without understanding what the flags actually mean. Your conveyancer’s job is to explain these findings clearly and distinguish between serious problems and minor technicalities. This is where professional advice prevents unnecessary withdrawals from purchases or, conversely, protects you from proceeding with genuinely problematic properties.
Timing mistakes create cascading delays. If searches are ordered late, they arrive close to your planned exchange date. If findings require investigation, you’re forced to either exchange without understanding the implications or delay exchange, which affects your completion date and moving plans. Mortgage lenders have conditions attached to their offers. If completion is delayed because of search issues, your mortgage offer could expire and you’d need a new offer. Your property’s chain could collapse if the seller becomes frustrated with delays. These timing risks multiply when searches arrive late. Ordering searches immediately after your offer is accepted, not weeks later, prevents these problems.
This summary highlights common risks and pitfalls for buyers skipping or misunderstanding searches:
| Risk Type | Potential Impact | How to Avoid |
|---|---|---|
| Missed Contamination | Expensive remediation, lost value | Order comprehensive searches |
| Planning Surprise | Loss of privacy, unwanted development | Request full council searches |
| Flood Risk | High insurance, resale difficulties | Always include flood searches |
| Unclear Results | Unwise decisions, legal exposure | Seek solicitor’s explanation |
| Late Searches | Delayed exchange/completion | Order immediately after offer |
London buyers face specific search risks that other regions don’t. The city’s historical industrial use creates higher contamination risks, requiring thorough environmental searches. The Thames and network of smaller watercourses create genuine flooding risk that demands professional flood searches. Listed building status and conservation areas are common in London, restricting what you can do with the property. Underground infrastructure like the Tube system can affect land stability in certain areas. These aren’t scaremongering points. They’re genuine risks that London searches must specifically investigate.
Pro tip: Budget for the full range of searches upfront and order them immediately after your offer is accepted, then build in two weeks minimum to review findings and investigate any concerns before exchange of contracts.
