Can I Mortgage a Contaminated Land Investment?

Contaminated land can be a challenging mortgage prospect. A lender needs to ensure you have budgeted for the clean-up operation to bring disused land back into good condition. Read on for all the facts about contaminated land investments and the applicable mortgage rates.

About your mortgage

Error: Yearly income income must be between £1 and £10,000,000.

Error: Regular bonus must be between £1 and £10,000,000.

Based on your yearly income, you may be able to borrow:


Most lenders will let you borrow 4.5 times your annual salary so, as long as you have a standard 10% deposit, you should be able to borrow this much.


Depending on your personal circumstances, some lenders may let you borrow 5 times your salary.


Lenders usually cap the amount they lend at 5.5 times your salary, so it’s unlikely you’ll be able to borrow more than this.

This calculator is an estimation of how much you could borrow. If you’re ready to take out a mortgage, speak to a Revolution brokers to see what options are available.

Can I Mortgage a Contaminated Land Investment?

Buying land that is contaminated, or property on contaminated land, can be a significant challenge when it comes to securing a competitive mortgage.

A lot depends on the type of contamination, the anticipated cost of remedial works, and how likely it is that the lender could resell the land or property in a repossession scenario.

Lenders will conduct a risk assessment and decide whether the loan is viable depending on these factors.

In this guide, the Revolution Brokers team summarises how mortgages are impacted by the land being contaminated and what questions to expect from a lender. For more advice and help with finding a mortgage for a home on contaminated land, give us a call on 0330 304 3040.

What Constitutes Contaminated Land?

Contaminated land includes any property or land parcel where there are pollution factors, such as chemicals, asbestos, gases, oils, solvents or heavy metals.

Your likelihood of mortgage approval will depend on how severe the contamination issue is and what health risks it poses to people and animals, as well as environmental pollution risks.

Land can become contaminated for many reasons, often due to commercial activities, mines, factories or mills nearby releasing by-products and harmful waste materials. Contaminations can also occur when old buildings have been demolished and may remain present for many years.

For most mortgage applicants, the first thing to do is run an Environmental Search to clarify precisely what the risks are, covering factors such as:

  • Flooding
  • Stability
  • Radon
  • Contaminants

If the Search returns a low-risk result or identifies that there are no dangerous contaminants, you should be able to apply for a mortgage as usual.

Where properties are considered contaminated, a risk status will be assigned, from low to high.

Should you already own the property, you might be required to cover the costs of remediation or cleaning and removing the contamination, as set out by the Environmental Protection Act.

You can also request a Warranty Certificate for the property from the seller. This cover note will provide insurance for the cost of managing or cleaning contaminated land provided it is dated after 1st April 1999.

How Can I Get a Mortgage on Contaminated Land?

There are a few options available:

  • Residential contaminated land indemnity insurance protects you from a remediation notice's cost implications and can reduce the risk factor.
  • Search for a lender with flexible criteria around contaminated land that will consider the application provided there are safeguards in place.
  • Source a specialist mortgage provider who may consider land mortgages with oversight of the remediation plan.

Another option could be to look at a bridging loan for the land purchase, including financing for remediation work costs. When the contamination is removed, it should then be possible to remortgage on a long-term product at regular rates.

Independent Advice on Contaminated Land Mortgages

The critical factor is to assess exactly the situation, how serious the contamination is, and what can be done to rectify the potential risks and remove the contamination from the land or property.

By working with an independent, whole-of-market broker, you have the best chance of finding mortgage lending, or another suitable borrowing product, to carry out remedial works on contaminated land and improve the saleable value of the property.
