Problems found after you bought · Contaminated land
When I bought this property, I didn’t know Contaminated land could hold up a sale or a remortgage. Now I’m stuck.
Would you have bought the property if you had known?
If you had known what the environmental search would show before you committed, and understood the problems it could cause when you later came to sell or remortgage, would it have changed your decision?
- Would you have paid the same price?
- Would you have wanted it investigated first?
- Would you have walked away?
If knowing about the problem might have changed what you did, the next question is obvious.
Did you receive the right advice when you bought?
You may not know the answer yet. But if nobody explained the problem, or you are now questioning what you were told at the time, that is worth looking at.
You don’t need to know whether anyone was at fault. Tell us what happened and when you bought. We’ll talk it through with you.
Why contaminated land can hold up a sale or remortgage
Contamination risk commonly enters a transaction through the contaminated-land element of an environmental search. This is a desktop screening report rather than a site investigation or determination that the land is contaminated. It compares the property against records including historical land use, landfill and industrial activity. The provider then gives an outcome under its own methodology, commonly “Passed” or “Further Action”, although terminology varies. A Further Action result is sometimes described informally as a failed environmental search.
What the outcome means is often misunderstood in both directions. A result recommending “Further Action”, sometimes described informally as a failed environmental search, does not establish that the land is contaminated. It means the provider could not screen out the identified risk and has recommended another step, which may involve further records, enquiries, specialist review or investigation. Equally, a “Passed” result is not a clean bill of health: the report may still identify historical land uses that become relevant if the land is developed or disturbed.
What holds up the sale or remortgage is that the result must be understood and addressed. Depending on the reason for it, the response may involve clarification from the search provider, further records, specialist assessment or investigation, evidence of previous remediation, or an indemnity policy where the proposed lender’s, buyer’s and insurer’s requirements permit it. Requirements differ between lenders and providers.
How the problem usually surfaces
The search recommends further action
The provider does not issue a “Passed” result and recommends specified enquiries, review or investigation. This is often described informally as a failed environmental search, but it is not proof of contamination.
A landfill or former industrial use nearby
The search identifies a landfill site or historical industrial activity nearby and, applying the provider’s methodology, recommends further action. Proximity is a screening indicator rather than proof of contamination.
A Passed result that still flags past land use
The outcome is a pass, but the report notes historical use that could matter if the land were ever developed or disturbed.
You are asked to pay for the policy
The buyer wants a contaminated land indemnity policy in place at your expense before exchange.
The policy protects the lender
A policy exists from an earlier purchase, but it was written to protect the lender’s security rather than the owner.
You want to extend or redevelop
Plans for an extension or other work change the question, because disturbing the ground is treated differently from leaving it alone.
What you can do about it now
Read the actual result rather than the rating. Ask your conveyancer for the report itself and establish which rating was given, on what basis, what sites or past uses were identified and what the report itself recommends. The pages the report refers you to usually matter more than the summary on the front.
Then establish what already exists. The seller may have commissioned their own report, there may be an indemnity policy from a previous purchase, and there may be disclosure in the property information form. An existing policy is worth finding before anyone pays for another, and its schedule will show whose benefit it was written for.
Take advice before commissioning intrusive investigation, contacting the local authority or arranging insurance. Intrusive investigation or contact with the authority may affect the availability of some policies, but preserving insurance should not displace appropriate investigation where there may be an actual risk to health, the environment or a proposed development. An indemnity policy responds only to the losses and remediation liabilities defined in it; it does not establish that the land is clean or safe. Its insured parties, exclusions, limits and treatment of future development must be checked.
If you are selling, your conveyancer can ask the buyer’s solicitor what remains unresolved and whether it arises from the buyer’s lender’s requirements. If you are remortgaging, your conveyancer can check your proposed lender’s requirements directly.
What happened when you bought?
An environmental search is commonly obtained on a purchase, so there may be a result on your historical file. A desktop search would not normally, by itself, establish the presence, absence or extent of contamination, although it may report an existing formal determination or site-specific evidence. Further assessment or investigation may therefore have been recommended. The questions are whether a search was obtained, what it showed, whether any further investigation was recommended and carried out, whether a policy was taken and for whose benefit, and what you were told about building on the land in future.
Several records from the time may matter, and some may survive. The environmental search shows the rating given and the sites or uses identified. There may be a report commissioned by the seller, and an indemnity policy whose schedule shows who was insured and against what. The replies your conveyancer received may show what was asked. The completion statement may show who paid for the policy. The lender’s historical written instructions may also be difficult to recover, because they are revised regularly and superseded versions disappear from public view.
Was this property really mortgageable when you bought?
Getting a mortgage when you bought does not necessarily tell you how readily mortgageable the property was across the wider market. There are two historical questions worth asking.
What did your own lender’s written requirements say about contaminated land when you bought? And what express requirements did other lenders have recorded at the same time?
Lenders’ written requirements were not necessarily uniform, and their wording changed over time. That means both which lender you used and when you bought can matter.
Lenders set out in writing what they expect a conveyancer to do about particular features of a property. Those instructions are revised regularly, and superseded versions drop out of public view, which can make a question as simple as what was my conveyancer told about contaminated land in the year I bought? surprisingly difficult to answer from the sources available today. Lexsure has retained historical lender-specific conveyancing requirements since April 2007, so where the records permit they can help reconstruct what your lender’s requirements said at the time and how that compared with the wider lending market.
Across that period, 14 lenders in our covered archive population have had express requirements about contaminated land on record, addressed across 2 separate places in their instructions. The earliest express appearance we can identify in the material we hold dates from 2008; the most recent recorded change of wording is 2026.
Two points of precision, because they matter. “Earliest identified” means the earliest express appearance in the material we hold, not the date any requirement began. And where our material for a particular lender and period is incomplete, that lender is left out of these figures rather than counted as having said nothing. We do not treat an incomplete record as showing that the lender had no requirement.
So, when did you buy?
Changing the year here doesn’t send us an enquiry or tell us who you are.
An example of the kind of wording in force 2007 to 2011
One lender’s requirements, not named, by way of illustration. Requirements were not uniform and this is not the wording that applied to your purchase — that depends on your lender and your completion date.
No lender handbook Part-2 (specific) requirements were published prior to . But professionals were still under a duty of care on this topic. It is still worth speaking to us even if the purchase predates .
If we find no express requirement for your lender
Where our material for your lender and period is complete, the answer may simply be that no express wording about contaminated land appears in it. Where our material is incomplete, we treat that as a gap in what we hold, not as evidence that your lender said nothing.
Either way, the lender’s instructions are only one part of the record from the time.
The wider picture
Historical lender requirements can help us understand how mortgageable the property was when you bought. The conveyancing file and the advice given to you also matter.
Lexsure holds historical Report on Title material: the reports conveyancers sent to homebuyers, going back years. That material shows the kinds of contaminated land issues that were being addressed when firms reported to buyers, and it is a second and separate record from what lenders required.
What the search showed
Were you told what rating the environmental search gave, on what basis, and what the report itself said the rating meant?
Whether further investigation was advised
Where the report recommended further enquiries or testing, were you advised to obtain them, and was anything obtained?
The policy, and whose benefit it served
If an indemnity policy was arranged, were you told what it covered, who paid for it and whether it protected you or only your lender?
Whether the limits on developing were explained
Were you told that a rating dealt with the land as it stood, and that building on or disturbing it could raise the question again?
Whether the effect on selling was explained
Were you told the search result would be raised again on a future sale or remortgage, and could matter to a buyer’s lender?
These are examples of issues addressed in historical conveyancing material, not a checklist of what every purchaser should have been told. What mattered in an individual purchase depended on the circumstances and on what was known at the time.
So even if your mortgage completed, or there is nothing unusual in your lender’s historical requirements, it can still be worth talking to us about what happened.
Could this problem have been seen coming?
The relevant starting point is what was known, or could reasonably have been identified, when you bought.
What did the environmental search show? What further investigation was advised? What was in the conveyancing file? What were mortgage lenders requiring at the time? What kinds of contaminated land issues were conveyancing firms addressing with homebuyers? And what were you actually told?
Taken together, that can help build a picture of whether the problem you are facing today was already something that should have been considered when you bought.
Did you receive the right advice?
What the historical evidence can tell us
Where the relevant lender and period are covered, we may be able to establish what that lender’s conveyancing requirements said when you bought, and how that compared with the wider record at the time.
- That does not by itself establish that anyone was negligent, or that you have a claim. Those questions need the original file and legal advice.
- The absence of express wording does not establish that the lender accepted the issue.
- What your conveyancer had to tell your lender and what they had to tell you are different questions, and the second depends on the retainer and the circumstances.
Time limits apply, and in some cases the date on which you first knew enough about the problem matters as well as the date you bought, which is why we ask about both. Our full methodology, including how we treat gaps in the record, is set out in the archive and its limits. Where a solicitor later needs formal historical evidence, Lexsure can provide source-evidenced historical lender information.
Sources and review
This page is about contamination risk reported on an environmental search. The same search commonly also reports flood risk, radon and ground stability; for flooding, see flood risk. Where a development or a planning condition dealing with contamination is involved, see missing planning permission. Guidance here about the present problem is general information. It is not legal advice about your property, and questions about the condition of the land itself are for a suitably qualified specialist.
The statutory regime governing contaminated land, and who may be required to remediate it, is set by the Environmental Protection Act 1990 and associated statutory guidance. Separate statutory guidance applies in England and Wales, and the relevant jurisdiction must be identified. This page describes how contamination risk is reported in a conveyancing transaction rather than setting out that regime, and it states no thresholds or liability rules; the current position must be verified at each review. Environmental search ratings are the product of the search provider’s own methodology, which differs between providers and changes. This page states no lender requirement as a general rule, because requirements differ between lenders and change.
Historical lender information is drawn from Lexsure’s archive of lender-specific conveyancing requirements, maintained since April 2007. Figures on this page state the population they are drawn from.

Counts cover substantive changes to lender requirements relevant to this topic in Lexsure’s records. That requirements changed is a fact about the market, not about your purchase.
