* Notes to Editors 
 
Costain is one of the UK's leading construction and engineering companies and is 
currently at the forefront of the drive to develop and improve the nation's 
infrastructure. 
 
In its targeted sectors, Costain is playing a major role in the provision of new 
facilities for a range of sectors ranging from waste to transport. The Company's 
strategy is entitled 'Choosing Costain'  and everyone in the organisation is 
committed to making Costain the automatic choice in terms of both business and 
technical excellence. 
 
Costain's origins date back to 1865. Since then the Company has featured in some 
of the world's major construction projects including the Channel Tunnel. Now the 
Company focuses on specific sectors within three divisions: Infrastructure - 
Highways, Rail, Airports and Nuclear sectors;  Environment - Water, Waste, 
Marine and Education sectors;  Energy & Process - Nuclear Process, Power and 
Hydrocarbons & Chemicals sectors. 
 
Costain has a strong order book. Significant contract awards include the GBP397 
million contract (design, construction and commissioning of 44 different 
facilities) for the Greater Manchester Waste Disposal Authority. In addition, 
Costain has won (as part of the 4D consortium) a GBP225 million contract with 
Southern Water to manage the design and build of a new waste water treatment 
works in the Brighton and Hove area. Costain is also heavily involved in the 
Nuclear sector and, in the Summer of 2009, announced the award of a GBP297 
million contract for full Engineering, Procurement, Construction and Inactive 
Commissioning of the Evaporator D project at Sellafield. 
 
The Company's status was underlined at the Construction News 2009 Quality Awards 
when Costain won the Supreme Award for best overall performance. More recently, 
the Company was named 'Contractor of the Decade' by New Civil Engineer at the 
magazine's annual awards in London in August 2010. 
 
 
Chairman's and Chief Executive's Statement 
 
Overview 
 
Costain has delivered a strong operational and financial performance in a 
continuing difficult economic environment. In the first half of the year, we 
have achieved growth in revenue, profit from operations and profit before tax. 
 
The Group's operations continue to benefit from its 'Choosing Costain' strategy 
to focus on targeted blue chip customers in chosen sectors whose major spending 
plans are underpinned to a degree by strategic national needs, regulatory 
commitments or essential maintenance requirements. Costain has a proven scale 
and capability to successfully deliver complex solutions in markets with 
significant potential including power, waste, rail and nuclear. We will continue 
to broaden our capability in providing a range of lifecycle solutions to our 
customers. 
 
The Company was named 'Contractor of the Decade' by New Civil Engineer at the 
magazine's annual awards in London in August 2010, underlining Costain's status 
as a leading player in the construction market. 
 
 
Results 
 
Revenue, including the Group's share of joint ventures and associates, for the 
half year ended 30 June 2010 was up 5% at GBP533.4 million (2009: GBP508.2 
million).  Profit from operations was GBP8.8 million (2009: GBP8.3 million), an 
increase of 6%.  Profit before tax increased by 19% to GBP8.2 million (2009: 
GBP6.9 million).  Basic earnings per share increased to 10.0 pence (2009: 8.7 
pence - restated following the 1 for 10 share consolidation in 2010). 
 
Net cash at 30 June 2010 stood at GBP133.9 million (2009: GBP119.2 million), 
while our average month end cash balance during the first six months of the year 
was GBP114.1 million (2009: GBP125.9 million) reflecting the variable timing of 
receipts and payments. 
 
As a result of a number of further significant contract awards since the 
beginning of the year, the order book at 30 June 2010 has been maintained at 
GBP2.5 billion (2009: GBP2.5 billion). Approximately GBP1.0 billion of work has 
been secured for 2010. We also had in excess of a further GBP500 million in 
preferred bidder positions (2009: over GBP700 million) and the Group has so far 
secured GBP570 million of revenue for 2011 (2009: GBP690 million for 2010). 
 
 
Dividend 
 
The Board has declared an increased interim dividend of 3.00 pence per share 
(2009: 2.75 pence - restated following the 1 for 10 share consolidation in 
2010).  The dividend will be paid on 29 October 2010 to those shareholders on 
the register as at the close of business on 24 September 2010. 
 
 
Pension 
 
The deficit in the Group's legacy defined benefit pension scheme as at 30 June 
2010 was GBP56.3 million net of deferred tax, a reduction of GBP19.1 million 
from the position as at 31 December 2009.  The assumptions and sensitivities 
used in the valuation of the pension scheme are set out in the notes to the 
interim financial statements. 
 
We are in the process of finalising the formal actuarial valuation of the scheme 
as at 31 March 2010, together with the associated recovery plan. 
 
 
 
 
 
 
Operational Review 
 
In line with Costain's strategy, we recently amalgamated the Environment and 
Community activities into a single enlarged Environment division which, together 
with the Infrastructure and Energy & Process divisions, form the core focus for 
the development of the Group's operations. 
 
Environment 
 
Revenue, including share of joint ventures and associates, during the period was 
GBP246.7 million (2009: GBP301.1 million), with a profit from operations of 
GBP1.2 million (2009: GBP2.6 million). 
 
In line with strategy, the enlarged Environment division will focus on new 
opportunities particularly in the water and waste markets and meeting the needs 
of existing long-term customers. 
 
The profit in the division has been impacted by costs associated with the 
amalgamation of the enlarged division, bidding activity particularly for waste 
PFI opportunities, and for a provision taken for anticipated additional costs on 
a marine project. 
 
The division had an order book of GBP1.3 billion at 30 June 2010. 
 
Costain is one of the UK's leading providers of water infrastructure solutions. 
During the period, the Group secured an AMP5 extension to its existing 
relationship with Dwr Cymru Welsh Water. This appointment is in addition to the 
AMP5 relationships previously secured with Severn Trent, Southern Water and 
United Utilities. 
 
Work has also continued, in joint venture, on the GBP225 million Brighton and 
Hove waste water treatment works contract for Southern Water. 
 
Since the period end, the Group has also been awarded a contract by Severn Trent 
to undertake work outside of the AMP5 framework on its Frankley facility. 
 
Good progress continues to be made in the delivery of the GBP397 million Greater 
Manchester Waste Authority contract, the largest waste services contract in 
Europe. Costain is actively engaged in submission of PFI proposals for major 
waste facilities and further opportunities in this growing sector. 
 
In order to continue to reduce costs and to focus resources in line with its 
strategy, the Group has closed and disposed of a facility at Erith, previously 
part of the marine sector activities.  The land and property sale generated a 
net profit of GBP1.3 million.  In addition, the Group closed a small regional 
office in Birmingham. 
 
Since the period end, Financial Close has been achieved on the Deptford Green 
PFI school contract, part of the Group's existing Lewisham Building Schools for 
the Future ('BSF') concession. The Lewisham programme is one of the BSF schemes 
that will continue. 
 
Infrastructure 
 
Revenue, including share of joint ventures and associates, during the period was 
GBP223.8 million (2009: GBP164.0 million), with a profit from operations of 
GBP8.0 million (2009: GBP6.8 million). 
 
Our Infrastructure division, which undertakes the Group's activities in the 
highways, rail and airports sectors, continues to perform well. 
 
The increase in revenue and profit reflects our focus on this activity and the 
market opportunities that are available for organisations with the scale, 
capability and track record to successfully deliver major complex projects for 
customers. 
 
The order book has been maintained at GBP1.0 billion and the level of tendering 
activity remains high. 
 
Costain, in joint venture, has been awarded a five-year GBP115 million Managing 
Agent Contractor ('MAC') contract by the Highways Agency to carry out routine 
operational and maintenance services in Area 14, which covers the North-East of 
England. This fourth MAC contract has helped establish Costain as a major player 
in the highways maintenance market. We are now pursuing a number of local 
authority highways maintenance opportunities. 
 
The Group has also been appointed, in joint venture, as one of the Delivery 
Partners to the Highways Agency's National Framework Contract involving the 
delivery, subject to budgetary review, of up to GBP2 billion early schemes in 
the Managed Motorway Programme. 
 
In rail, Costain, in joint venture, has been appointed to construct tunnel 
portals for Crossrail as part of the enabling works framework contract for this 
important infrastructure project. 
 
Since the period end, we have been appointed, in joint venture, by London 
Underground Limited preferred bidder for the redevelopment of Bond Street 
station. 
 
Good progress continues to be made on the delivery of the major 66MW waste to 
energy plant for AE&E at Belvedere. 
 
We continued work on the long-term contract for Manchester Airport Group and are 
also delivering a number of projects at Gatwick airport. 
 
 
Energy & Process 
 
Revenue, including share of joint ventures and associates, during the period was 
GBP62.4 million (2009: GBP42.5 million), with a profit from operations of GBP3.1 
million (2009: GBP2.7 million). 
 
The division, which comprises activities in hydrocarbons & chemicals, nuclear 
process and power, has delivered a good first half performance with growth in 
revenue and profit. The level of business development cost has been increased in 
the period and additional key resources have been added to the team in line with 
potential growth opportunities in this area. 
 
The order book was GBP0.15 billion. 
 
In nuclear process, progress continues to be made on the engineering and 
construction of the Evaporator D project at Sellafield, one of the UK's largest 
nuclear decommissioning projects. 
 
The Group continues to build its capability in the power sector and business 
development activities are progressing, including for the UK's nuclear new build 
programme which is gathering pace. 
 
Further orders have been received from E.ON for the gas plant for the 
underground storage facility being constructed at Holford in Cheshire.  In 
addition, the operation in Abu Dhabi continues to undertake a number of 
contracts on the Das Island oil and gas facility. 
 
Land Development 
 
Revenue for the period was GBP0.5 million (2009: GBP0.6 million) with a loss 
after tax of GBP0.5 million (2009: loss of GBP0.7 million). The loss in the 
period reflects running costs similar to those in the prior period. 
 
The Alcaidesa joint venture does not undertake direct residential development in 
Spain but has acquired over time a land bank for which it seeks to secure Master 
Plan approval and build infrastructure prior to selling on developable land to 
third parties. 
 
As previously announced, activity has been scaled back until the Spanish 
development market improves and maximum shareholder value can be secured for the 
assets. 
 
Work on the construction of the 600-berth yacht marina and associated commercial 
development at La Linea de la Concepcion is progressing well. The first phase of 
the project, which is immediately adjacent to the Spanish border with Gibraltar, 
opened on 2 August 2010 and the first berth sales and rentals have been 
achieved. 
 
 
Risks and uncertainties 
 
The Board continuously assesses and monitors the key risks of the business. 
Despite the current uncertainty in the global economy, the key risks that could 
affect the Group's medium term performance, and the factors which mitigate these 
risks, have not significantly changed from those set out on pages 40 to 42 of 
the Group's Annual Report for 2009, a copy of which is available from our 
website www.costain.com. 
 
The Business Review and the notes to these interim financial statements include 
consideration of uncertainties affecting the Group in the remaining six months 
of the year. 
 
 
Outlook 
 
Costain has again delivered a good result for the first half of the year. It is 
testimony to the Group's strategic focus and leading market positions that, in 
one of the most testing economic environments, Costain continues to deliver a 
strong operational and financial performance. 
 
We are successfully implementing the 'Choosing Costain' strategy, focusing on 
major customers with spending plans that are underpinned by strategic needs, 
regulatory commitments or essential maintenance requirements. 
 
As a consequence, the Group entered the second half of the year with a good 
order book, robust finances and a net cash balance in excess of GBP100 million. 
Whilst challenging market conditions are set to continue for the foreseeable 
future, the Board expects to report continued progress at the year-end in line 
with its expectations.

Notes to the interim financial statements 
 
1.       General information 
 
Costain Group PLC (the Company) is a public limited company incorporated in the 
United Kingdom.  The address of its registered office and principal place of 
business is Costain House, Vanwall Business Park, Maidenhead, Berkshire SL6 4UB. 
 
 
The condensed consolidated interim financial statements are presented in pounds 
sterling, rounded to the nearest hundred thousand. 
 
The comparative figures for the financial year ended 31 December 2009 are not 
the Company's full statutory accounts for that financial year. Those accounts 
have been reported on by the Company's auditors and delivered to the Registrar 
of Companies. The report of the auditors was (i) unqualified, (ii) did not 
include a reference to any matters to which the auditors drew attention by way 
of emphasis without qualifying their report, and (iii) did not contain a 
statement under section 498 (2) or (3) of the Companies Act 2006. 
 
After making enquiries and reviewing the latest forecasts, the directors believe 
that the Group has adequate resources to continue in operational existence for 
the foreseeable future. Accordingly, they continue to adopt the going concern 
basis in preparing the interim financial statements. 
          2.       Statement of compliance 
 
This interim financial information for the half-year ended 30 June 2010 has been 
prepared in accordance with IAS 34 Interim Financial Reporting as adopted by the 
European Union and with the Disclosure and Transparency Rules of the Financial 
Services Authority.  The interim financial information should be read in 
conjunction with the Annual Report for the year ended 31 December 2009. 
 
Except as described below, the accounting policies and presentation applied in 
this condensed set of financial statements are consistent with those described 
in the Annual Report for the year ended 31 December 2009. 
 
The Board approved the unaudited interim financial statements on 24 August 2010. 
 
The Group's principal risks and uncertainties are consistent with those noted in 
the Annual Report for the year ended 31 December 2009.  The Directors consider 
that the significant areas of judgement made by management that have significant 
effect on the Group's performance and estimates with a significant risk of 
material adjustment in the second half of the year are unchanged from those 
identified on page 111 of Annual Report for the year ended 31 December 2009. 
 
(i)      Change in accounting policy 
 
IFRIC12 applies to contractual arrangements whereby a private sector operator 
participates in the development, financing, operation and maintenance of 
infrastructure for public sector services, typically under PFI arrangements. The 
Group is a party to these arrangements through certain of its investments in 
joint ventures and associates. The adoption of IFRIC 12 has not resulted in any 
significant changes to the assets recorded within the Group's investments 
although there is a change in the timing of profit recognition over the lifetime 
of the contract.  Importantly, there is no change in the overall project cash 
flows arising, or on the directors' valuation.  IFRIC 12 has been adopted in the 
period with retrospective effect.  The effect of adoption on comparative amounts 
was immaterial and so comparative amounts have not been restated. 
 
(ii)     Change in operating segments 
During the period, the Group changed its internal management and reporting 
structure and combined the activities previously reported separately as its 
Environment and Community activities into a single enlarged Environment segment. 
Comparative segment information has been restated accordingly. 
 
 
          3.       Business segment information 
The Group now has four business segments: Environment, Infrastructure, Energy & 
Process and Land Development operations in Spain. As noted above, the activities 
previously reported separately as Community have been combined into a single 
enlarged Environment segment and comparative segment information has been 
restated accordingly. The segments are   strategic business units with separate 
management and have different core customers or offer different services.

          4.       Net finance (expense)/income 
Finance income includes the expected return on the assets of the pension scheme 
of GBP14.8 million (2009 half-year GBP11.7 million, 2009 year GBP23.4 million) 
and finance expense includes the expected increase in the present value of the 
pension scheme liabilities of GBP15.8 million (2009 half-year GBP14.2 million, 
2009 year GBP28.2 million). The expected return and the increase in present 
value are based on the value of assets and liabilities of the pension scheme at 
the start of the period.

+-------------------------------------+-----------+----------+-----------+----------+--------+ 
The effective corporation tax charged represents the estimate of the tax rate 
for the full year. No account has been taken in these interim financial 
statements of the reduction in corporation tax from 28% to 27% with effect from 
1 April 2011.  If that 1% change had been applied to the deferred tax asset at 
30 June 2010, a reduction of GBP1.0 million would have arisen (GBP1.4 million 
charged to reserves and GBP0.4 million credited to the interim tax expense 
above). 
A further reduction to reflect the proposed corporation tax rate of 24% from 1 
April 2014 would reduce the deferred tax asset by GBP3.0 million. 
 
          6.       Earnings per share 
            The calculation of earnings per share is based on profit for the 
period of GBP6.4 million (2009 half-year GBP5.5 million, 2009 year GBP14.6 
million) and the number of shares set out below:

The proposed interim dividend of 3.00 pence (2009: 2.75 pence - restated 
following the 1 for 10 share consolidation in 2010) has not been included as a 
liability in these interim financial statements because it had not been approved 
at the period end date.  The dividend totalling GBP1.9 million will be paid on 
29 October 2010 to shareholders on the register at the close of business on 24 
September 2010.  A scrip dividend alternative will be offered. 
 
          8.       Property, plant and equipment 
 
During the interim period, the Group spent GBP0.6 million on plant and equipment 
(2009 half-year GBP5.5 million, 2009 year GBP7.0 million), and GBPNil on 
leasehold property (2009 half-year GBPNil, 2009 year GBP0.2 million).  During 
the period, the Group closed one of its offices and sold the adjacent land for 
net proceeds of GBP2.5 million (2009 half-year GBPNil, 2009 year GBPNil). The 
Group also sold plant and equipment during the period for net proceeds of GBP1.1 
million (2009 half-year GBPNil, 2009 year GBP0.4 million).

Independent review report to Costain Group PLC 
 
 
Introduction 
We have been engaged by the company to review the condensed set of financial 
statements in the half-yearly financial report for the six months ended 30 June 
2010 which comprises the Condensed consolidated income statement, the Condensed 
consolidated statement of comprehensive income, the Condensed statement of 
changes in equity, the Condensed consolidated statement of financial position, 
the Condensed consolidated cash flow statement and the related explanatory 
notes. We have read the other information contained in the half-yearly financial 
report and considered whether it contains any apparent misstatements or material 
inconsistencies with the information in the condensed set of financial 
statements. 
 
This report is made solely to the company in accordance with the terms of our 
engagement to assist the company in meeting the requirements of the Disclosure 
and Transparency Rules ("the DTR") of the UK's Financial Services Authority 
("the UK FSA"). Our review has been undertaken so that we might state to the 
company those matters we are required to state to it in this report and for no 
other purpose. To the fullest extent permitted by law, we do not accept or 
assume responsibility to anyone other than the company for our review work, for 
this report, or for the conclusions we have reached. 
 
Directors' responsibilities 
The half-yearly financial report is the responsibility of, and has been approved 
by, the directors. The directors are responsible for preparing the half-yearly 
financial report in accordance with the DTR of the UK FSA. 
The annual financial statements of the company are prepared in accordance with 
IFRSs as adopted by the EU. The condensed set of financial statements included 
in this half-yearly financial report has been prepared in accordance with IAS 34 
Interim Financial Reporting as adopted by the EU. 
 
Our responsibility 
Our responsibility is to express to the company a conclusion on the condensed 
set of financial statements in the half-yearly financial report based on our 
review. 
 
Scope of review 
We conducted our review in accordance with International Standard on Review 
Engagements (UK and Ireland) 2410 Review of Interim Financial Information 
Performed by the Independent Auditor of the Entity issued by the Auditing 
Practices Board for use in the UK. A review of interim financial information 
consists of making enquiries, primarily of persons responsible for financial and 
accounting matters, and applying analytical and other review procedures. A 
review is substantially less in scope than an audit conducted in accordance with 
International Standards on Auditing (UK and Ireland) and consequently does not 
enable us to obtain assurance that we would become aware of all significant 
matters that might be identified in an audit. Accordingly, we do not express an 
audit opinion. 
 
Conclusion 
Based on our review, nothing has come to our attention that causes us to believe 
that the condensed set of financial statements in the half-yearly financial 
report for the six months ended  30 June 2010 is not prepared, in all material 
respects, in accordance with IAS 34 as adopted by the EU and the DTR of the UK 
FSA.
