 I, Martin McDermott, certify  that: 

| 1.     | I have reviewed this annual report on Form        20-F, and all reports on Form 6-K containing distribution or servicing        reports filed in respect of periods included in the year covered by this        annual report, of HOLMESFINANCING (NO.4) PLC;                                                                                                                                  |

| 2.     | Based on my knowledge, the information in        these reports, taken as a whole, does not contain any untrue statement        of a material fact or omit to state a material fact necessary to make        the statements made, in light of the circumstances under which such statements        were made, not misleading as of the last day of the period covered by    this annual report; |
|   |                                                                                                                                                                                                                                                                                                                                                                                           |
| 3.     | Based on my knowledge, the distribution        or servicing information required to be provided to the trustee by the        servicer under the pooling and servicing, or similar, agreement, for    inclusion in these reports is included in these reports;                                                                                                                                  |
|   |                                                                                                                                                                                                                                                                                                                                                                                           |
| 4.     | Based on my knowledge and upon representations        made to me by the servicer, and except as disclosed in the reports, the        servicer has fulfilled its obligations under the servicing agreement;    and                                                                                                                                                                              |
|   |                                                                                                                                                                                                                                                                                                                                                                                           |
| 5.     | The reports disclose all significant deficiencies        relating to the servicer's compliance with the minimum servicing standards    based upon representations made to me by the servicer.                                                                                                                                                                                                  |
