Pre-offer property report vs solicitor's conveyancing searches

Last updated: 2026-10-02

Quick answer

A pre-offer property report and a solicitor's conveyancing searches are not the same thing and do not substitute for each other. A pre-offer report (£9.99 Lite or £24.99 Complete) is a desk-based screen of public hazard and area records, run before you make an offer, to help you decide whether to proceed. Official conveyancing searches (Local Authority LLC1 and CON29, Drainage and Water, Environmental) are legal searches ordered by your solicitor after the offer is accepted. One is triage. The other is diligence. You almost always want both, in that order.

Dimension	Pre-offer HouseCheckup report	Solicitor's conveyancing searches
Stage	Before you make an offer	After the offer is accepted and the solicitor is instructed
Who orders it	You, directly, for one address	Your conveyancer, on your instructions
Status	Unofficial pre-purchase screen	Formal legal searches relied on by the lender
Typical cost	£9.99 Lite / £24.99 Complete	£250–£450 plus VAT and local-authority disbursements, varies by council
Turnaround	within 24 hours, usually faster, hand-prepared	10 working days to several weeks depending on the council
Flooding	National flood mapping and recorded flood extents where published	Not covered by the standard local search; an optional flood-specific search is sometimes added
Ground stability and coal	BGS screening and coal-mining proximity	Formal CON29M coal-mining search where the property is in a coal area
Contaminated land	Not covered: we do not issue a contaminated-land liability opinion	Environmental Search returns a formal liability opinion
Planning history	Available designations and nearby application history	CON29 returns the formal planning position on the title
Who relies on it	You, the buyer	Lender, conveyancer and (indirectly) your buildings insurer

Our verdict

Order a pre-offer report before you offer, and let your solicitor order the official searches once the offer is accepted. A pre-offer report runs 15+ public-source checks on the address and names what it could not answer. It will not replace the Local Authority, Drainage and Water, or Environmental Search, but it does tell you whether the property is worth spending £400 of legal fees to find out.

Why the two documents are at different stages of the purchase

The British purchase process puts legal diligence after an offer is accepted, not before. A conveyancer is instructed, searches are ordered, and ten working days to several weeks later a bundle of formal replies lands on your solicitor's desk. By that point you have agreed a price, you may have paid for a RICS survey, and the emotional weight of walking away is at its heaviest. That gap between offering and knowing is exactly where a pre-offer report earns its £9.99–£24.99 cover charge: it moves the flooding, ground-stability and planning questions to the point where you still have the option to not offer at all.

What the two documents can and cannot say about the same risk

A pre-offer report and a conveyancing search can both touch flooding, for instance, but they do so with different authority. A pre-offer report cites the Environment Agency's national flood map, Natural Resources Wales flood extents, and (in Scotland) SEPA mapping, and shows what the map says at the address. A conveyancer buying an optional environmental search gets a liability opinion that a lender and insurer treat as a legal input. Neither replaces the other. The map helps the buyer decide; the formal search protects the transaction.

When a pre-offer report is enough on its own

It never is, for a mortgaged purchase. Your lender will not release funds without the standard conveyancing search pack. The pre-offer report is complementary: it does the question-forming so that the conveyancing stage goes faster and so that you do not pay for legal searches on a property you were always going to walk away from once you saw the subsidence pattern on the street. If you are a cash buyer, the official searches are still strongly recommended, both to price your insurance correctly and to catch any Section 106 charge that follows the title.

Frequently asked questions

No. A HouseCheckup report is an unofficial pre-offer screen compiled from public records so a buyer can decide whether to proceed to offer. A solicitor's conveyancing search pack (the Local Authority Search, Drainage and Water Search, and Environmental Search at a minimum) is a later legal step that a lender and a conveyancer rely on, ordered after the offer is accepted and the solicitor is instructed. The two overlap in subject matter (flooding, mining, planning history) but they are ordered at different stages, serve different parties, and carry different legal weight. One helps you decide whether to make an offer. The other protects the transaction once you have.

No. Official conveyancing searches are ordered by the solicitor and are mandatory for most mortgaged purchases, and the lender's CML Handbook treats them as a condition of release. A pre-offer report has no legal standing in the transaction. Treat it as triage before you commit, not as a substitute for the official searches your solicitor arranges once your offer is accepted.

Three main things. First, timing: the report is run before you make an offer, which is when the information is most valuable to a buyer deciding whether to proceed. Second, scope: it brings together area context (crime, schools, transport, planning history), sold-price comparables, and energy data that sit outside the official conveyancing scope. Third, framing: it is written for a non-specialist buyer and names what it cannot answer at the address, rather than returning a legal yes/no.

Legally relevant answers from the local authority: Section 106 planning agreements and CIL charges on the title, pending planning enforcement, highway adoption status, radon affected area status under the HPA scheme, and the formal CON29O questions where your conveyancer thinks the property warrants them. The Drainage and Water Search returns the public sewer map and water company records. The Environmental Search returns a liability opinion on contaminated land. These are legal searches with professional sign-off; a desk-based report cannot replace them.

The pre-offer report, because it costs less and is useful before the money gets committed. Conveyancing searches cost £250–£450 plus VAT and disbursements, and they are ordered after your offer is accepted. A pre-offer report at £9.99 Lite or £24.99 Complete gives you the questions to ask before you ever sign a Memorandum of Sale. If the report flags something serious (recorded flooding, a coal shaft within 20m, a flood zone 3 designation), you can walk away or re-price without having paid any legal fees.

No. The LLC1 (Local Land Charges) and CON29 forms are documents ordered from the local authority or via HM Land Registry's Local Land Charges service by a conveyancer. The data a HouseCheckup report draws on overlaps with their subject matter (planning history, conservation area status, listed building status), but the formal LLC1 and CON29 are legal searches that only your solicitor can order and only they can rely on in the transaction.
