When you buy a property, one of the most important parts of the conveyancing process is property searches. These aren’t optional extras or bureaucratic boxes to tick. They’re essential checks that uncover critical information about the property, the land it sits on, and the local area — and missing them is one of the biggest risks a buyer can take.
The Three Core Searches
These three searches form the foundation of any property purchase, ordered together as the Full Search Pack on virtually every transaction.
1. Local Authority Search
Your window into local council records. Covers planning history, building control approvals, completion certificates, enforcement notices, road adoptions, listed building status, smoke control orders, and environmental notices affecting the property.
Why it matters: Protects you from inheriting planning problems. An extension built without permission could need to be removed at your cost. If access roads aren’t adopted by the council, you may be liable for maintenance. Listed building status means future renovations require planning approval.
Timeline: 2–3 weeks as part of the Full Search Pack
2. Environmental Search
Investigates historical and current environmental risks: contaminated land, former industrial uses, landfill sites, ground stability and subsidence risk, flood risk, and radon gas levels.
Why it matters: Environmental contamination can be invisible but hugely expensive. Remediating contaminated land, managing flooding, or dealing with subsidence can cost tens of thousands. Insurance claims for environmental issues are notoriously difficult. This search gives you hard data before you commit.

3. Water & Drainage Search
Confirms whether the property connects to mains water and public sewers, where pipes are located, and any known drainage issues in the area.
Why it matters: If the property has a private septic tank instead of mains drainage, maintenance is your responsibility — often £1,000–£3,000 every few years. If a water main runs under your garden, digging without knowing could leave you with a large bill. This search also reveals if the water company has recorded supply or sewerage problems in your area.

I’m a Cash Buyer — Do I Really Need Searches?
The short answer: yes, absolutely.
We hear this question often. If you’re not borrowing money, does it matter what the searches say? The answer is a firm yes — and in fact, cash buyers have even more to lose.
- No lender to do the legwork for you. When you have a mortgage, your lender requires searches and uses them to protect their security. As a cash buyer, you’re entirely responsible for due diligence. Skipping searches isn’t being efficient — it’s flying blind.
- You can’t shift liability. If the property has undisclosed planning issues, contamination, or drainage problems, you own the problem outright. There is no institutional protection.
- Resale complications. When you come to sell, your buyer’s lender will still require searches. If problems emerge then, they may refuse to lend, killing the sale — or you’ll be forced to reduce the price significantly.
- Hidden costs dwarf search fees. A Full Search Pack costs £150–£300. Remediating contamination or fixing planning breaches can cost £5,000–£50,000+. That’s a harsh lesson in false economy.
- Insurance won’t cover what you should have known. Many property issues aren’t insurable because they’re discoverable through searches. Skip them and claim later, and you’ll likely be rejected.
- Negotiation leverage. If searches reveal issues, you can ask the seller to fix them, reduce the price, or withdraw before exchange. Without searches, you have no warning and no leverage.
Specialist Searches: When You Might Need Them
Beyond the three core searches, certain properties or locations require additional checks. Your solicitor will advise if any apply to your purchase.
Chancel Repair Liability
An ancient obligation where, in some rural areas, property owners can be liable for repairing parts of a local church. Primarily relevant to older rural properties near parish churches.
Timeline: 3–5 days
Mining Search
Identifies whether the property is in an area with past or present mining activity — coal, tin, slate, lead. Mining can cause subsidence, sinkholes, and ground instability. Essential in South Wales, the Midlands, Lancashire, Yorkshire, and parts of the Southwest.
Timeline: 3–5 days
Coal Authority Search
A specific search for properties in designated coal mining areas. The Coal Authority keeps detailed records of past mining activity and subsidence risk. Usually required in Central and Northern England even when a general mining search has been done.
Timeline: 3–5 days
Japanese Knotweed Search
Japanese knotweed is an invasive plant that damages property structures and can be extremely costly to eradicate. Some lenders won’t mortgage properties with known knotweed. Often a specialist survey is needed alongside the search if knotweed is suspected.
Timeline: 3–5 days
Radon Gas Search
Radon is a naturally occurring radioactive gas that accumulates in some properties. Particularly relevant in Devon, Cornwall, and parts of Central England. The standard Environmental Search includes radon data, but a dedicated search provides more detailed risk assessment.
Timeline: 3–5 days
What Can Go Wrong Without Searches?
- Planning breach: A buyer discovered after completion that an extension was built without permission. The council ordered it removed — over £20,000 in demolition and rebuilding costs.
- Private drainage: A property had an undisclosed septic tank. When it failed, repairs cost £8,000. The buyer had no warning and no recourse against the seller.
- Subsidence: A property in a former mining area had a history of subsidence claims. Without a mining search, the buyer inherited the risk — £15,000 in repairs and £3,000 annual insurance premiums.
- Contaminated land: An old factory site was redeveloped into housing. Buyers who skipped the environmental search discovered contamination after completion. Resale value dropped 15% and specialist insurance became near-impossible to obtain.
The common myth: “The seller would have told me”
No, they wouldn’t — and they’re not legally required to. Seller disclosure is limited and often incomplete. Searches are your independent verification from official records. Relying on what a seller tells you is a risk; relying on official records is protection.
Why Searches Take Time
The Full Search Pack typically takes 3–4 weeks because local authorities and water companies process requests in batches and cross-reference multiple data sources. This is why we recommend ordering searches early — ideally as soon as your offer is accepted. Waiting until later risks delaying your exchange and completion date.
At Ethical Conveyancing we include a Full Search Pack as standard on every quote. If specialist searches are needed during your transaction we will let you know, explain what they cover, and arrange them for you.
