Cavity Wall Insulation Extraction Finance

    Finance your Cavity Wall Insulation Extraction in 3 easy steps


    Reportedly there are over 3 million homes that have been identified along the West coast alone as stated in the British Research Establishment report dated 18th March 2015/303-500.1.

    Of course, this figure will be much greater on a UK wide basis, houses that suffer from damp, mould and other related issues attributed solely to failed Cavity Wall Insulation. This is caused by either incorrectly installed Cavity Wall Insulation either by incompetent, non-accredited installers or unscrupulous companies taking advantage of the previous lack of technical monitoring and installing CWI in properties not in a suitable condition.


    Fully extract all of the insulation and reinstate the cavities back to where they should have been before any insulation was introduced, and at the same time remove any other obstructions within the cavity wall void. This means clearing the cavity of rubble and debris and any other materials that should not be there because they could contribute to damp issues within the property.


    The process of Cavity Wall Insulation Extraction is straightforward albeit labour intensive, taking on average 1 or 2 days with two technicians, it requires specialist machinery fit for this purpose and should only be carried out by Oscar Onsite accredited technicians who are able to adhere to the established Method Statement which outlines the procedures.

    Property Technical Surveys are carried out by specially trained Surveyors who have completed and passed the Oscar Onsite CWI Extraction Course which will fully equip them to identify the issues which are then placed into a formal technical report. This report will form the basis of the remedial works required to be carried out by the Approved Oscar Onsite Extractor company. All evidence from the extraction is uploaded by the Technicians and uses data such as photographs, borescope and/or thermal images as required as evidence.

    Upon completion, a final Oscar Onsite inspection is carried out to confirm and stating the property is fully reinstated with clear unobstructed cavities. This ensures that a fully compliant and robust procedure is in place therefore reducing the risk of any future liabilities.

    Extraction Companies who wish to embark on the Oscar Onsite Cavity Extraction Accreditation will be required to have all technicians assessed by Oscar Onsite and approved through a mix of theory and onsite assessments which will determine the technician’s competence along with the Extraction companies Quality Management processes and insurance cover.

    Importantly clients such as Homeowners have expressed their concerns that the incompetent, non-accredited companies who put it in the now failed insulation should not be allowed to come back to take it out! as a result they welcome the Oscar Onsite Scheme as it provides them with added security.

    What is Buy Now Pay Later (BNPL)?

    Buy Now Pay Later or BNPL is a convenient way to pay for purchases through credit. The customer enters into a credit agreement with Duologi whereby they have an initial payment free period (or deferred period) followed by a monthly repayment period in which to pay off the loan as per the loan agreement.

    Does the customer have to pay interest during the payment free period?

    No, as long as the customer pays off the entire credit amount before the end of the last day of the payment free period, they will only have to pay the original loan amount with zero interest.

    Are there any monthly payments to be made during the payment free period?

    There are no monthly payments to be made during the payment free period by the customer.

    What happens if a customer does not pay off the loan by the last day of the payment free period?

    If the customer wishes to rollover the loan beyond the payment free period, they will need to start making monthly payments starting one month after the last day of the payment-free period. The number of monthly payments will be stated in the terms of the agreement.

    Will the customer have to pay interest if they have rolled over the loan after the payment free period?

    Yes, if the customer rolls over the loan after the payment free period, they will have to pay interest as per the terms of the loan agreement and as quoted to them before the agreement is formally signed by them.

    From when is the interest applicable?

    Once the customer rolls over the loan after the payment free period, interest will be payable by them at the quoted APR from the date of the original loan.

    Please refer to the following example:

    Original loan date: 1/1/2018
    Loan Term: 48 month term
    Deferred (i.e. payment free) term: 12 months
    Therefore, payment term: 36 months
    APR: 19.5%
    Rollover date: 1/1/2019
    Interest payable after rollover: At APR 19.5% from original loan date, i.e. 1/1/2018

    The interest and capital repayment amount will have been quoted to the customer as part of the customer journey before they sign the agreement.

    Can a customer settle part of the loan?

    Yes, the customer can settle part or the full amount outstanding of the loan at any time by calling our Customer Services team on the number provided.

    Will Duologi notify the customer with a reminder when they are approaching the end of the payment free period?

    Yes, as a responsible lender, Duologi will send a written reminder to the customer at least 4 weeks in advance of them approaching the end of the payment free period to enable them to make a decision whether to settle the loan in full before the end of the payment free term or to rollover.

    Is there a minimum purchase amount for BNPL to be available to the customer?

    Yes, like our other credit products, BNPL purchases are subject to minimum and maximum loan amounts. Please refer to the rate card agreed as part of the RTA for details.
