Independent Accountant's Report on Applying Asset Agreed Upon Procedures

The Board of Directors of<br> **Holmes Master Issuer PLC**<br> 2 Triton Square<br> Regent's Place<br> London<br> NW1 3AN<br> United Kingdom<br> (the "**Issuer**")

The Board of Directors of<br> **Santander UK PLC** <br> 2 Triton Square<br> Regent's Place<br> London<br> NW1 3AN<br> United Kingdom<br> (the "**Seller**")

**Banco Santander, S.A.**<br> Ciudad Grupo Santander<br> Edificio Encinar<br> Avenida de Cantabria s/n<br> 28660 Boadilla del Monte<br> Madrid<br> Spain<br> (the "**Arranger**")

4 April 2026

Dear Sirs/Madams,

**Agreed-upon procedures engagement relating to the 2026 annual update (the "Update") of the Holmes Master Issuer plc residential mortgage-backed note programme (the "Programme")**

We have performed the procedures enumerated below on certain residential mortgage loans (the "Loan Pool"), which were agreed to by the Issuer, the Seller and the Arranger (as defined in the Engagement Letter). The procedures were performed to assist you in evaluating the validity of certain characteristics of the Loan Pool. This agreed upon procedures engagement was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants. The appropriateness of these procedures is solely the responsibility of the Issuer, the Seller and the Arranger. Consequently, we make no representation regarding the appropriateness of the procedures described below either for the purpose for which this report has been requested or for any other purpose.

This report (the "Asset Agreed Upon Procedures Report") is addressed to the Board of Directors of the Issuer, the Board of Directors of the Seller and the Arranger identified in the Engagement Letter who have agreed to participate in the proposed Update.

Deloitte LLP is a limited liability partnership registered in England and Wales with registered number OC303675 and its registered office at 1 New Street Square, London, EC4A 3HQ, United Kingdom.

Deloitte LLP is the United Kingdom affiliate of Deloitte NSE LLP, a member firm of Deloitte Touche Tohmatsu Limited, a UK private company limited by guarantee ("DTTL"). DTTL and each of its member firms are legally separate and independent entities. DTTL and Deloitte NSE LLP do not provide services to clients. Please see www.deloitte.com/about to learn more about our global network of member firms.© 2026 Deloitte LLP. All rights reserved.

![](duediligence001.jpg)

These procedures were established with the Issuer and the Seller and the appropriateness of the procedures is solely the responsibility of the Issuer, the Seller and the Arranger as discussed above. The Issuer and the Seller shall be solely responsible for providing accurate and complete information requested by Deloitte necessary to perform the procedures. Deloitte has no responsibility for the accuracy or completeness of the information provided by or on behalf of the Issuer and the Seller, even if Deloitte had reason to know or should have known of such inaccuracy or incompleteness.

The procedures that we performed and our findings are as follows:

**1. Scope of our work and factual findings**

The procedures performed were as defined in Appendix 2 of the Engagement Letter (the "Agreed Upon Procedures").

The Seller provided us with a data file 'Holmes_AUP_List.xlsx' (the "First Pool Run") containing a loan identifier for each of the 50,449 loans with greater than zero current balance in the Loan Pool.

A random sample of 458 loans was selected from the First Pool Run (the "Sample") using the sampling approach below.

The Seller then provided the data file 'HT_AUD_FEB26_Data_Tape.xlsx' (the "Sample Pool") containing information for each loan in the Sample as at 31 January 2026 (the "Cut-off Date").

We have carried out the Agreed Upon Procedures on the Sample Pool during the period 17 February to 20 March 2026.

**The sampling approach**

Sampling confidence is the probability that the actual errors, within a total population, are contained within the range of an estimate. Precision is the range of that estimate. The precision limit is the estimated maximum predicted number of errors within the total population. Sampling confidence and precision are stated in percentages.

Attribute sampling is a method of assessing the rate of occurrences of a specified attribute in a population and requires agreed upon procedures in relation to certain characteristics of a random sample of individual loans. In this case the Agreed Upon Procedures related to the documentation and procedures that support the Sample Pool contained in the First Pool Run.

Our method of calculating attribute sample sizes is based on the binomial probability distribution.

Statistical tests can only provide estimates of the error.

The procedures we have undertaken, set out in paragraphs 2.1 to 2.24 under the pool agreed upon procedures section below, has been limited to confirming that the selected attribute from the Sample Pool information relating to the First Pool Run agreed to the original loan documentation or copies thereof provided to us in the loan file. We are entitled to assume that the loan documentation is correct and we have not sought to independently verify this information. The loan documentation used in these Agreed upon Procedures was the offer letter, additional borrowing offer letter, credit limit review, Certificate of Title ("CoT"), the completion letter, Official Copy of Register Entries, original or latest valuation report (the "valuation report") or subsequent valuer's letter, the personal identification documentation, the ANMF system (the "System") and the data file 'HT_AUD_FEB26_Back_ups.xlsx' (the "System extract").

**Objectives**

On the assumption that the information in the First Pool Run is a complete and accurate representation of the Loan Pool, the sample sizes chosen were designed with the objective of us being able to state that there is a 99% confidence that not more than 1% of the population of the First Pool Run contained an error in the relevant attribute. Where errors were found in the Sample Pool, we have re-calculated the percentage errors that there might be in the First Pool Run and noted the revised percentage below. It is for you to ensure you understand this basis of reporting and to determine whether the errors are acceptable to you and for the purposes of the Update.

![](duediligence001.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Pool agreed upon procedures** 

<br> For each loan in the Sample Pool, we carried out the following agreed upon procedures and have given a confidence and precision percentage for each procedure.

For the purposes of this report, the failure of a single attribute is termed an error.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.1 Borrower Name

In cases where the surname of one borrower changed to the surname of a joint borrower, we were informed by the Seller that such changes are as a result of changes in the marital status of the borrowers. For the avoidance of doubt, we did not agree that any change in the surname of the borrower was due to a change in their marital status, as no evidence of changes to the marital status was available in the mortgage files.

In relation to procedures 2.1.1-2.1.2 below, substantially agreed is defined as being able to identify the borrower's name where minor spelling errors or reversals of initials had occurred.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.1.1. For each loan in the Sample Pool, we
 confirmed whether the borrower name(s) shown on the Sample Pool substantially agreed to that
 shown on the offer letter, additional borrowing offer letter or credit limit review. We found
 that the borrower name(s) shown on the Sample Pool substantially agreed to the offer letter,
 additional borrowing offer letter or credit limit review, except for 1 case.

As a result of the procedure performed there is a 99% confidence that not more than 2% of the First Pool Run contained errors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.1.2. For each loan in the
 Sample Pool, we confirmed whether the borrower name(s) shown on the Sample Pool substantially
 agreed with that shown on the CoT or Official Copy of Register Entries. We found that the
 borrower name(s) shown on the Sample Pool substantially agreed to the CoT or Official Copy
 of Register Entries, except for 1 case.

---

As a result of the procedure performed there is a 99% confidence that not more than 2% of the First Pool Run contained errors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2 Property Address

We were instructed by the management of the Seller that this procedure should not include agreeing the postcode if other segments of the property address were sufficient to identify the property. In addition, for new build properties, we were instructed by the management of the Seller that, where the original plot address and final full postal address differ, these differences are expected as a mortgage progresses from application to completion and thus these should not be considered to be errors if the property address was not substantially changed. For the avoidance of doubt, if the postcode was missing, incomplete or incorrect, or if the original plot address and final full postal address did not substantially differ, they were not considered to be an error.

In relation to procedures 2.2.1-2.2.3 below, substantially agreed is defined as being able to identify the property address where minor spelling errors has occurred.

![](duediligence001.jpg)

2.2.1. For each loan in the Sample Pool, we confirmed
 whether the property address shown on the Sample Pool substantially agreed with that shown
 on the offer letter, additional borrowing offer letter or credit limit review. We found that
 the property address shown on the Sample Pool substantially agreed to the offer letter, additional
 borrowing offer letter or credit limit review, with no exception.

As a result of the procedure performed there is a 99% confidence that not more than 1% of the First Pool Run contained errors.

2.2.2. For each loan in the Sample Pool, we confirmed
 whether the property address shown on the Sample Pool substantially agreed with that shown
 on the valuation report. We found that the property address shown on the Sample Pool substantially
 agreed to the valuation report, except for 5 cases.
