When you buy a home in England or Wales, your solicitor will order a bundle of enquiries from the local council before you exchange contracts. This is the local authority search, and it is one of the standard checks that make up pre-exchange due diligence, the background work done to confirm what you are actually buying. It pulls together information the council holds about the property itself and, to a limited extent, the land immediately around it: planning history, building regulations sign-offs, the adopted status of nearby roads, entries on the local land charges register, and similar matters of public record.
This guide is written for buyers, sellers who want to understand what their buyer's solicitor is doing, and anyone remortgaging where the new lender requires searches. It covers the two core documents that make up a full local authority search in England and Wales: the LLC1, which lists local land charges registered against the property, and the CON29, which answers a set of standard enquiries about planning, roads, and building control history.
One point worth flagging early: turnaround times and even the format of the results vary considerably between councils, and later in this article Lauren Basger explains why.
The Two Core Documents: LLC1 and CON29 Explained
When your conveyancer orders local authority searches UK buyers routinely rely on, two forms sit at the heart of the report: the LLC1 and the CON29.
The LLC1 is a copy of entries held on the Local Land Charges Register. It flags anything legally binding on the property itself, regardless of who owns it. That includes financial charges (money owed to the council, for example unpaid works), conservation area designations, listed building status (which restricts what you can alter), tree preservation orders (TPOs, meaning you cannot lop or fell protected trees without consent), and smoke control zones (which limit what fuels you can burn). If something appears here, it travels with the property.
The CON29 is broader and asks the council direct questions about the area around the home. You will see a planning history, permissions granted, refusals, and pending applications, plus building regulations completion certificates confirming past works were signed off. It also covers enforcement notices (formal action against unauthorised development), whether the road serving the property is adopted (maintained at public expense) or unadopted, the status of public highways, nearby road schemes and traffic proposals, contaminated land entries under Part IIA of the Environmental Protection Act 1990, and whether the property sits in a radon affected area.
Beyond that sits the optional CON29O, a menu of extra enquiries you pay for only when relevant. Lauren Basger, solicitor, notes these are worth raising selectively rather than by default: common land or town green registration for rural plots, pipeline notices where a major utility runs nearby, and houses in multiple occupation (HMO) records if you are buying a let property or a converted flat. Ordering the right optional enquiries early avoids a second round of questions later.
When the Search Is Ordered, Who Pays and How Much It Costs
Your solicitor usually orders local authority searches UK buyers rely on shortly after the draft contract pack arrives from the seller's side, and once you've paid searches on account (a small upfront payment that covers third-party fees). Sending funds early matters. Nothing goes to the council until that money clears, so any delay in paying pushes everything else back.
The buyer pays for searches, not the seller. That reflects the wider principle in a purchase in England and Wales: it's the buyer who needs to understand what they're taking on, from planning history to road status and building regulations records held on the CON29 form.
Fees vary between councils, and there's also a difference between an official search (ordered directly from the local authority) and a personal search (carried out by a private company using council data). Prices shift over time and differ by area, so your solicitor will confirm the current cost before ordering.
One point worth flagging early: most lenders require searches to be less than six months old at exchange of contracts. If a transaction drags on, results can go stale and need reordering. Lauren Basger notes that turnaround times swing widely by council, which is why building in time from the start helps.
Official Council Searches vs Personal and Regulated Searches
An official local authority search is submitted directly to the council, which pulls the answers from its own records and returns the results on headed paper. A personal or regulated search is carried out by a private search company that accesses the same underlying public data, planning registers, building control records, highways information, and compiles the report in the same CON29 format.
The results should, in theory, match. In practice, solicitors sometimes recommend a regulated search because it can come back faster when a council's own turnaround is slow, and because reputable providers back their reports with professional indemnity insurance. If something is missed or misreported, the buyer has a route to recover losses from the insurer rather than being left without recourse.
Whether a lender will accept a regulated search depends on its entry in the UK Finance Mortgage Lenders' Handbook (previously the CML Handbook) Part 2. Part 2 sets out each lender's specific requirements, and preferences vary, some accept regulated searches without issue, others insist on an official council search, and a few impose conditions on the provider or the search's age. Your solicitor will check the relevant Part 2 entry before instructing either type.
Lauren Basger, solicitor, notes that local authority search turnaround times vary widely by area because councils differ in staffing, digitisation of records, and how planning and highways data is stored, which is often what drives the choice between official and regulated in the first place.
Solicitor Insight: Why Turnaround Times Vary So Much by Area
One of the most common frustrations in a conveyancing transaction is the unpredictability of local authority searches UK-wide. A buyer down the road might get their results in under a week, while yours takes over a month. The reason usually has nothing to do with your file, it's structural.
Lauren Basger, solicitor, points out that the biggest single factor is whether the council has digitised its Local Land Charges Register (the official record of restrictions and financial charges affecting a property). Councils that still hold paper or partially scanned records simply take longer to search. Related to this is the phased migration to HM Land Registry's centralised Local Land Charges service, a national programme rolling out council by council. Areas already migrated tend to return the LLC1 (the official certificate of land charges) almost instantly; those still waiting sit in a queue managed locally.
Staffing matters too. Many councils are still working through backlogs that built up during and after the pandemic, and search teams are often small. Dense urban boroughs with decades of layered planning history, extensions, changes of use, enforcement notices, take longer to compile than a rural district with less recorded activity. It's also worth noting that the CON29 (which covers planning decisions, adopted roads, and building regulations history) is frequently handled by a different department to the LLC1, so one part of your search can move quickly while the other stalls.
Regulated search providers can sometimes bypass council delays for the LLC1 by producing a personal search, but the CON29 replies still come from the council itself.
Lauren advises against relying on quoted turnaround figures for named councils, as they shift week to week. Your solicitor can check the current position with the relevant authority when your search is ordered.
Reading the Results: Red Flags and When to Raise Further Enquiries
Once your local authority searches UK results land, the job is to spot entries that need explaining before you exchange contracts.
An unresolved enforcement notice (a formal council order requiring works or the removal of unauthorised building) is a serious one, it stays with the property, not the seller. Missing building regulations completion certificates for extensions or loft conversions are common and often fixable, but they mean nobody has confirmed the work meets safety standards. If the property fronts an unadopted road (a road the council does not maintain), check whether a maintenance agreement exists between the frontagers; without one, future repair costs could fall on you.
Contaminated land entries, planning applications on neighbouring land that could affect light or outlook, and tree preservation orders (TPOs, which restrict pruning or felling) sitting over trees you intended to remove for an extension all deserve close reading.
Lauren Basger, solicitor, notes that turnaround times vary widely because some councils still work from part-digitised registers while others have fully searchable systems, and staffing levels differ across authorities. That is why a result arriving quickly in one district may take considerably longer in the next.
Ask your solicitor to raise additional enquiries with the seller where an entry is ambiguous or documents are missing. Indemnity insurance can be appropriate for a missing building regs sign-off on older works, provided no one approaches the council for a retrospective inspection. Where the finding is material, active enforcement, significant contamination, or a TPO blocking your plans, it may justify renegotiating the price or, in some cases, withdrawing from the purchase.
Common Pitfalls Buyers and Sellers Should Avoid
One of the most common mistakes is relying on a search the seller obtained months, or even years, earlier. Lenders generally expect local authority searches UK-wide to be recent, and circumstances shift: a neighbour's planning application, a new road scheme, or an enforcement notice can appear between the old search date and your purchase. If in doubt, order a fresh one.
Another trap is assuming that a clear result means there is nothing to worry about. Searches only reveal what the council itself records. They will not pick up private disputes, boundary disagreements, or issues affecting neighbouring properties beyond the specific questions asked on the CON29. A "no entry" answer is narrower than many buyers assume.
Indemnity insurance also gets misused. It can help where a historic risk is dormant and unlikely to surface, but it is not a replacement for proper investigation where a live problem exists. Lauren Basger notes that insurance is often reached for too quickly, when a targeted enquiry to the council would give a clearer answer.
Finally, planning entries are easy to misread. Permitted development rights, which normally allow certain works without a full application, may have been withdrawn locally by an Article 4 direction. Always check whether such a direction applies before assuming an extension or change of use is straightforward.
Next Step: Speak to a Conveyancing Solicitor
Local authority searches uk buyers rely on are not a tick-box exercise. They are a core part of a safe purchase in England and Wales, flagging planning history, road status, and building regulations records that can materially affect what you are buying. The raw result is only half the story. Interpretation is what turns a stack of entries into a clear view of risk, and that is where a conveyancing solicitor earns their fee.
Instructing a solicitor early matters. Searches can only be ordered once you are formally on board, and some councils process requests far more quickly than others. When you make first contact, ask upfront about typical turnaround in the specific local authority area, so your expectations are grounded in reality rather than hope.
Lauren Basger notes that turnaround times vary widely by council, driven by staffing, systems, and local demand.
