Part I: Letter from the Chairman

22 March 2012

To the holders of ordinary shares

Dear Shareholder

Notice of Annual General Meeting

I am pleased to be writing to you with details of our Annual General Meeting, which we are holding at Aggreko UK Limited, Manufacturing, Lomondgate, Stirling Road, Dumbarton, G82 3RG on Wednesday 25 April at 10.30 a.m. The venue for the 2012 AGM is our new state-of-the-art manufacturing facility at Lomondgate in Dumbarton. The AGM will be held in the morning, before the official opening of the factory by HRH Princess Anne, the Princess Royal later in the day. Shareholders will be offered the opportunity for a tour of the new site after the AGM and before the official opening takes place. We anticipate that the day will conclude around 3.30pm. The formal notice of Annual General Meeting is set out in Part II of this circular.

If you would like to vote on the resolutions to be considered at the Annual General Meeting but cannot attend the meeting then you can appoint a proxy to exercise all or any of your rights to attend, speak and vote at the meeting by completing the proxy form sent to you with this circular and returning it to our Registrar at the address stated on the form. They must receive it by 10.30 a.m. on Monday 23 April 2012. Alternatively, you may appoint a proxy electronically by logging on to the Registrar's website, http://shares.aggreko.com provided that they receive details of your appointment by 10.30 a.m. on Monday 23 April 2012.

The Aggreko plc Annual Report and Accounts for the year ended 31 December 2011 and a copy of this circular have been published on the Company's website at www.aggreko.com, in the Investors section. To access these documents you will need to have Adobe Acrobat Reader installed on your computer. If you have elected to receive shareholder correspondence in hard copy form then a copy of the Annual Report and Accounts will accompany this circular. Should you wish to change your election at any time, or if you wish to request a hard copy of the Annual Report and Accounts, you can do so by contacting our Registrar, Capita Registrars, Shareholder Administration Support, 34 Beckenham Road, Beckenham, Kent BR3 9ZA or alternatively via http://shares.aggreko.com.

The following paragraphs provide an explanation of some of the resolutions to be considered at the Annual General Meeting.

Resolutions 1 to 16 will be proposed as ordinary resolutions. This means that for each of those resolutions to be passed, more than half of the votes cast must be in favour of the resolution. Resolutions 17 to 20 will be proposed as special resolutions. This means that for each of those resolutions to be passed, at least three-quarters of the votes cast must be in favour of the resolution.

Final dividend (Resolution 3)

Shareholders are being asked to approve a final dividend of 13.59 pence per ordinary share for the year ended 31 December 2011. If shareholders approve the recommended final dividend, it will be paid on 22 May 2012 to all ordinary shareholders who are on the register of members on 20 April 2012.

Re-election of Directors (Resolutions 4 to 12)

The Company's Articles of Association require that all Directors retire at least every three years and that all newly appointed Directors retire at the first AGM following their appointment. However, in accordance with the recommendations of the UK Corporate Governance Code, the Directors have agreed that they will all retire and, except for me, submit themselves for re-election by shareholders. At the Company's Annual General Meeting in 2011, I announced that I intended to step down as Chairman and also from the Board of Aggreko at the AGM in April 2012, at which point I will have served ten years as Chairman and fifteen years on the Board. My successor as Chairman will be Ken Hanna, who joined the Board in October 2010; Ken is Chairman of Inchcape plc and a Non-executive Director of Tesco plc.

Biographical information on each of the Directors seeking re-election is contained on pages 54 and 55 of the Annual Report and Accounts. The Board has confirmed that, following formal performance evaluation, all of the Directors standing for re-election continue to perform effectively and demonstrate commitment to their roles. The Board therefore unanimously recommends the re-election of the Directors proposed.

Authority to allot shares (Resolution 15)

Paragraph (a) of Resolution 15 will authorise the Directors to allot ordinary shares up to an aggregate nominal amount equal to £12,206,454 (representing 89,046,210 ordinary shares of 13$^{549}$/rnp each). This amount represents approximately one-third of the issued ordinary share capital of the Company as at 9 March 2012, being the latest practicable date prior to the publication of this circular. As at 9 March 2012 the Company held no treasury shares and there were no warrants over ordinary shares.

In line with guidance issued by the Association of British Insurers, paragraph (b) of Resolution 15 will authorise the Directors to allot additional ordinary shares in connection with a rights issue up to an aggregate nominal amount equal to £24,412,909 (representing 178,092,420 ordinary shares of 13$^{549}$/rnp each), as reduced by the nominal amount of any shares issued under paragraph (a). This amount (before any reductions) represents approximately two-thirds of the issued ordinary share capital of the Company as at 9 March 2012, being the latest practicable date prior to the publication of this circular.

Resolution 15 will be proposed as an ordinary resolution. The authorities sought under this resolution will expire on the earlier of 30 June 2013 (the latest date by which the Company must hold an Annual General Meeting in 2013) or the conclusion of the Annual General Meeting of the Company held in 2013.

The Directors have no present intention to issue new shares other than in relation to the issue of shares under the Company's executive and employee share schemes.

Directors' fees (Resolution 16)

The current Articles of Association limit the aggregate amount of fees that can be paid to Directors (other than Executive Directors' remuneration) to £500,000. Last year Directors' fees amounted to £430,999 in aggregate. In order to provide the Board with further flexibility it is proposed that the aggregate limit be increased to £750,000. The Articles of Association provide that this increase may be effected by an ordinary resolution of shareholders.

Disapplication of statutory pre-emption rights (Resolution 17)

Resolution 17 proposes, as a special resolution, to disapply the statutory pre-emption rights of shareholders on allotment of equity securities for cash up to an aggregate nominal value of £1,830,968 (representing 13,356,931 ordinary shares of 13$^{549}$/mp each), being approximately 5% of the current issued ordinary share capital of the Company. The Directors confirm that they do not intend to allot new shares on a non pre-emptive basis with a value of more than 7.5% of the current issued share capital over a three-year period.

This resolution also disapplies statutory pre-emption rights to the extent necessary to facilitate rights issues. The authority under this resolution will expire at the conclusion of the Annual General Meeting in 2013 or on 30 June 2013, whichever is the earlier. This resolution is on the same terms as approved last year and the Directors intend to seek renewal of this power at subsequent Annual General Meetings.

Purchase of own shares (Resolution 18)

The Directors recommend that shareholders renew the authority of the Company to purchase its own ordinary shares. Accordingly, Resolution 18 will be proposed as a special resolution seeking authority to make such purchases in the market. The Directors will only use this authority when they consider it to be in the best interests of shareholders generally and an improvement in earnings per share would result. Any ordinary shares purchased under this authority will either be cancelled (and the number of ordinary shares in issue reduced) or be held in treasury.

Resolution 18 specifies the maximum number of ordinary shares which may be purchased (representing approximately 10% of the Company's current issued ordinary share capital) and the minimum and maximum prices at which they may be bought, reflecting the requirements of the Companies Act 2006 and of the Financial Services Authority, as set out in the Listing Rules. The Directors intend to seek renewal of this power at subsequent Annual General Meetings.

As at 9 March 2012 there were options over 1,163,989 ordinary shares in the capital of the Company which represented 0.44% of the Company's issued share capital at that date. If the authority to purchase the Company's ordinary shares were exercised in full, these options would represent 0.44% of the Company's issued ordinary share capital.

Notice of general meetings (Resolution 19)

Under the Companies Act 2006 all general meetings of the Company must be held on 21 clear days' notice unless shareholders agree to a shorter notice period on an annual basis and certain other conditions are met. The Company is currently able to call general meetings (other than Annual General Meetings) on 14 clear days' notice. The Board is proposing Resolution 19 as a special resolution at the Annual General Meeting so that the Company can continue to be able to convene general meetings on 14 clear days' notice. The Board intends that this shorter notice period would not be used as a matter of routine, but would only be used where the flexibility was justified by the business of the meeting and it would be to the advantage of shareholders as a whole. If Resolution 19 is passed, the authority to convene general meetings on 14 clear days' notice will remain effective until the Company's next Annual General Meeting, when it is intended that a similar resolution will be proposed. The notice period for Annual General Meetings will remain 21 clear days.

Purchase of B shares (Resolution 20)

In March 2011 the Company announced a return of capital of around £150 million to shareholders by means of a B share structure. In July 2011 we returned around £148 million of this amount, but shareholders representing 6,663,731 shares elected to retain their B shares on the understanding that the Company would make a second offer to purchase them around the time of the Annual General Meeting in 2012. Resolution 20, which will be proposed on a special resolution, seeks authority for the Company to purchase further outstanding B shares for 55.5p per share (such price including the accrued B Share Continuing Dividend to which the holders of B shares are entitled under the Company's Articles of Association) to complete the return of capital. It is not intended that a further offer will be made by the Company for any B shares left outstanding following this second offer.

Recommendation

The Board considers that all the resolutions to be considered at the Annual General Meeting are in the best interests of the Company and its shareholders as a whole. Your Board will be voting in favour of them and unanimously recommends that you do so as well.

Yours sincerely,

Philip Rogerson
Chairman

Part II: Notice of Annual General Meeting continued

Notes

1. Attending the Annual General Meeting in person

If you wish to attend the Annual General Meeting in person, you should arrive at the venue for the Annual General Meeting in good time to allow your attendance to be registered. It is advisable to have some form of identification with you as you may be asked to provide evidence of your identity to the Company's Registrar prior to being admitted to the Annual General Meeting.

2. Appointment of proxies

Members are entitled to appoint one or more proxies to exercise all or any of their rights to attend, speak and vote at the Annual General Meeting. A proxy need not be a member of the Company but must attend the Annual General Meeting to represent a member. To be validly appointed a proxy must be appointed using the procedures set out in these notes and in the notes to the accompanying proxy form.

If members wish their proxy to speak on their behalf at the meeting, members will need to appoint their own choice of proxy (not the Chairman of the Annual General Meeting) and give their instructions directly to them.

Members can only appoint more than one proxy where each proxy is appointed to exercise rights attached to different shares. Members cannot appoint more than one proxy to exercise the rights attached to the same share(s). If a member wishes to appoint more than one proxy, they should contact the Company's Registrar, Capita Registrars, on Tel: 0871 664 0300 (calls cost 10 pence per minute plus network extras) (from outside the UK: +44 (0) 20 8639 3399). Lines are open Monday-Friday, 8.30 a.m.-5.30 p.m.

A member may instruct their proxy to abstain from voting on any of the resolutions to be considered at the meeting by marking the 'Withheld' option when appointing their proxy. It should be noted that an abstention is not a vote in law and will not be counted in the calculation of the proportion of votes 'for' or 'against' the relevant resolution.

The appointment of a proxy will not prevent a member from attending the Annual General Meeting and voting in person if he or she wishes.

A person who is not a member of the Company but who has been nominated by a member to enjoy information rights does not have a right to appoint any proxies under the procedures set out in these notes and should read note 9 below.

3. Appointment of a proxy online

As an alternative to appointing a proxy using the proxy form or CREST, members can appoint a proxy online at http://shares.aggreko.com. In order to appoint a proxy using this website, members will need their personal identification Investor Code. This information is printed in the top right hand corner of the proxy form. If for any reason a member does not have this information, they should contact the Registrar on Tel: 0871 664 0300 (calls cost 10 pence per minute plus network extras) (from outside the UK: +44 (0) 20 8639 3399). Lines are open Monday-Friday, 8.30 a.m.-5.30 p.m. Members may appoint a proxy using the website no later than 48 hours (excluding non-working days) before the time of the Annual General Meeting or any adjournment of that meeting.

4. Appointment of a proxy using a proxy form

A proxy form for use in connection with the Annual General Meeting is enclosed. To be valid any proxy form or other instrument appointing a proxy, together with any power of attorney or other authority under which it is signed or a certified copy thereof, must be received by post or (during normal business hours only) by hand by the Registrar at Capita Registrars, The Registry, 34 Beckenham Road, Beckenham, Kent BR3 4TU by no later than 48 hours (excluding non-working days) before the time of the Annual General Meeting or any adjournment of that meeting.

If you do not have a proxy form and believe that you should have one, or you require additional proxy forms, please contact the Registrar on Tel: 0871 664 0300 (calls cost 10 pence per minute plus network extras) (from outside the UK: +44 (0) 20 8639 3399). Lines are open Monday-Friday, 8.30 a.m.-5.30 p.m.

5. Appointment of a proxy through CREST

CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so by using the procedures described in the CREST Manual and by logging on to the following website: www.euroclear.com/CREST. CREST personal members or other CREST sponsored members, and those CREST members who have appointed (a) voting service provider(s), should refer to their CREST sponsor or voting service provider(s) who will be able to take the appropriate action on their behalf.

In order for a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (a 'CREST Proxy Instruction') must be properly authenticated in accordance with Euroclear UK & Ireland Limited's specifications, and must contain the information required for such instruction, as described in the CREST Manual. The message, regardless of whether it constitutes the appointment of a proxy or is an amendment to the instruction given to a previously appointed proxy, must in order to be valid, be transmitted so as to be received by the Registrar (ID RA10) no later than 48 hours (excluding non-working days) before the time of the Annual General Meeting or any adjournment of that meeting. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Application Host) from which the Registrar is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

CREST members and, where applicable, their CREST sponsors or voting service provider(s) should note that Euroclear UK & Ireland Limited does not make available special procedures in CREST for any particular message. Normal system timings and limitations will, therefore, apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member, or sponsored member, or has appointed (a) voting service provider(s), to procure that his CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting system providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.

The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.

1. Appointment of a proxy by joint holders

In the case of joint holders, where more than one of the joint holders purports to appoint one or more proxies, only the purported appointment submitted by the most senior holder will be accepted. Seniority is determined by the order in which the names of the joint holders appear in the Company's register of members in respect of the joint holding (the first named being the most senior).

1. Corporate representatives

Any corporation which is a member can appoint one or more corporate representatives. Members can only appoint more than one corporate representative where each corporate representative is appointed to exercise rights attached to different shares. Members cannot appoint more than one corporate representative to exercise the rights attached to the same share(s).

1. Entitlement to attend and vote

To be entitled to attend and vote at the Annual General Meeting (and for the purpose of determining the votes they may cast), members must be registered in the Company's register of members at 6.00 p.m. on Monday 23 April 2012 (or, if the Annual General Meeting is adjourned, at 6.00 p.m. on the day two days prior to the adjourned meeting). Changes to the register of members after the relevant deadline will be disregarded in determining the rights of any person to attend and vote at the Annual General Meeting.

1. Nominated persons

Any person to whom this notice is sent who is a person nominated under section 146 of the Companies Act 2006 (the '2006 Act') to enjoy information rights (a 'Nominated Person') may, under an agreement between him/her and the member by whom he/she was nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the Annual General Meeting. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he/she may, under any such agreement, have a right to give instructions to the member as to the exercise of voting rights.

1. Website giving information regarding the Annual General Meeting

Information regarding the Annual General Meeting, including information required by section 311A of the 2006 Act, and a copy of this notice of Annual General Meeting is available at www.aggreko.com in the Investors section.

1. Audit concerns

Members should note that it is possible that, pursuant to requests made by members of the Company under section 527 of the 2006 Act, the Company may be required to publish on a website a statement setting out any matter relating to: (a) the audit of the Company's accounts (including the auditor's report and the conduct of the audit) that are to be laid before the Annual General Meeting; or (b) any circumstance connected with an auditor of the Company ceasing to hold office since the previous meeting at which annual accounts and reports were laid in accordance with section 437 of the 2006 Act. The Company may not require the members requesting any such website publication to pay its expenses in complying with sections 527 or 528 of the 2006 Act. Where the Company is required to place a statement on a website under section 527 of the 2006 Act, it must forward the statement to the Company's auditor not later than the time when it makes the statement available on the website. The business which may be dealt with at the Annual General Meeting includes any statement that the Company has been required under section 527 of the 2006 Act to publish on a website.

1. Voting rights

As at 9 March 2012 (being the latest practicable date prior to the publication of this notice) the Company's issued share capital consisted of 267,138,630 ordinary shares, carrying one vote each; 6,663,731 B shares which do not carry voting rights except in limited circumstances, none of which are currently applicable; and 182,700,915 Deferred shares, which do not carry voting rights in any circumstances. Therefore, the total voting rights in the Company as at 9 March 2012 were 267,138,630 votes.

1. Notification of shareholdings
