1. What is a Mining Search?
A Mining Search is a concise report which assesses the likelihood of a property being affected by mining subsidence.
2. Why do I need one?
A Mining Search is required by mortgage lenders when a property changes hands or by the Local Planning Authority when land is to be developed in former mining areas.
3. What is involved?
A Mining Search is a desk top study prepared with reference to our extensive archive of plans, maps, manuscripts and digitised data. Thanks to our local knowledge and expert interpretation, the majority of our Searches are able to discount the subsidence risk to a property, even in heavily mined areas. If any potentially adverse features are highlighted, the report will illustrate the nature of the hazard and recommend the next steps.
4. How long does it take?
The Standard Mining Search report will take approximately 7 to 8 days to complete and issue electronically. An Expedited Mining Search service is available with a target turnaround of 48-hours.
5. How much does it cost?
  • Typical property (<1 acre):
    • Standard Search – £59.99 including VAT
    • Expedited Search – £89.99 including VAT
  • Larger site (1 – 5 acres):
    • Standard Search – £86.40 including VAT
    • Expedited Search – £129.60 including VAT
  • >5 acres – Contact us for a quote
  • An additional fee of £6 including VAT applies if we source a boundary plan on your behalf.
  • If you would like to talk about a quote, please Contact us
6. How do I order one?

You can order and pay for a Mining Search online by completing the information in a short series of steps. To complete the Search, we will need a plan highlighting the boundaries of the property. You can upload one if you have it, or we’ll order one (at additional cost).

If you prefer, you can contact us and pay over the phone, or send a request by email or post. We will still need a plan of the property. You can email or post this to us.

1. What is a Mining Investigation and why do I need one?
A Mining Investigation usually involves drilling boreholes or excavating trenches in order to provide detailed information on ground conditions, where a risk from hidden mine workings has been highlighted. This may be as a result of an adverse Mining Search, following a subsidence or prior to building development.
2. How much does it cost?

A typical Investigation of a single development plot starts from £702 (including VAT) when an excavator is sourced by the client. A two-day drilling investigation of a typical residential property costs around £3000 (including VAT). The cost, extent and type of investigation carried out depends on the nature of the suspected mining hazard, the layout of the property and the needs of the client. Please contact us for a customised quotation.

3. How long does it take?

For a typical residential property or development site a Mining Investigation can be completed and documented within two weeks of instruction. We will always work hard to meet your deadline, so please ask.

4. How do I instruct one?
Just call our Mining Investigations department and we will be pleased to take instruction over the phone. We will visit the property free of charge to discuss the remit of the investigation, answer any questions you might have and provide a customised quotation.
1. What is contaminated land?
Generally, contaminated land is a term used to describe land polluted by a range of potentially hazardous substances, including heavy metals. Heavy metals occur naturally in the rocks and soil of Cornwall and west Devon and may have become concentrated by former mining activity.
2. Why would I need a Land Contamination Assessment?

In former metal mining areas, the Local Planning Authority may require that the risk of contaminated land is assessed as a Condition of planning permission. So if you are building or developing or just extending property in the South West you are likely to need an assessment.

3. Where do I go for advice?

If you are thinking of buying land in the South West, or have reason to suspect that you may require a Land Contamination Assessment, please feel free to contact us for free, no obligation guidance.

4. What is involved?

A Contaminated Land risk assessment is a staged process.

 

 

 

The completion of each phase gives the opportunity to discount, mitigate against or further evaluate any risk. Phases range from an initial screen (non-interpretative report), to a desk study (Phase 1), soil sampling (Phase 2) and remediation strategies (Phases 3 – 5).

5. What type of assessment do I need?

You may not need all the stages of a Land Contamination Assessment.

See our Services page for more information or contact us if you are not sure what you need.

6. How much will it cost?

Prices from:

  • Metallic Contamination Search – £41.99 (including VAT)
  • Phase I Land Contamination Desk Study – £685 (including VAT)
  • Phase II Land Contamination Intrusive Investigation – POA
  • Phase III Remediation Method Statement – POA
  • Phase IV Remediation Verification Report – POA
7. How long does it take?

Phase I Desk Studies can be completed within 5 working days. The scope of Phase II, III and IV reports dictate how long they will take to prepare. Please Contact us for more information.

8. How do I instruct an assessment?

You can now instruct a Phase I assessment online by following the link below. This is currently available for small sites that meet certain criteria. For all other sites it is best to Contact us first and we can confirm what is needed, how much it will cost and how long it is likely to take.

1. What is mundic?

Mundic is a term unique to the South West. It refers to concrete that is sub-standard or prone to degrading because reactive materials, like mine waste, were used to make it.

2. How does it affect me?

The Council of Mortgage Lenders and Royal Institution of Chartered Surveyors (RICS) recognise that buildings constructed prior to 1950 in Cornwall and 1960 in West Devon may contain mundic concrete. Buildings that meet this criteria require a mundic test as part of the conveyancing process. It is usually the mortgage valuation surveyor who will determine if this is needed.

3. What is involved?

We will arrange a visit to the property to take cores of the concrete under the guidance of an RICS Surveyor. We then coordinate the laboratory testing and report, classifying the concrete into one of three possible grades. If the concrete does not pass, then further testing may be required to classify it. The end report is designed to be acceptable to all major mortgage lenders.

4. How much does it cost?

Stage 1 tests start from £370 (excluding VAT) for a typical residential property; however, this varies with property size, location, test history and nature of construction. Please Contact us for a customised quotation.

5. How long will it take?

Samples can normally be taken within 10 days of instruction. A verbal indication of the results can be requested within 2 to 3 working days. The final surveyor’s report is typically produced within 5 days of sampling.

MINESCANNER
1. What is MineScanner?
MineScanner is our bespoke interactive database of all known historic metallic mine workings in Cornwall, Devon and Somerset.
2. How does it work?
Just enter the postcode and MineScanner will perform an automated search of our extensive records to confirm whether the property lies within an area where mining subsidence may be a risk.
3. What does it mean if it says ‘Yes’, I need a Mining Search?
This does not mean there is definitely a mining threat to your property; however, MineScanner has identified a threat somewhere within a 2000m radius and that a Mining Search report is needed to discount or clarify any risks further.
4. What does it mean if it says ‘No’?

This means that our records do not indicate any historic mining activity has taken place within 2000m of the property. (See our Terms & Conditions for the limitations of this process).

5. What do I do next?

If MineScanner says ‘Yes’ – Click here to Order Mining Search. If MineScanner says ‘No’ and you require written confirmation that a Mining Search is not required, please contact us.
