TRADING UPDATE                                 

Interserve, the international services, maintenance and building group, today
provides a trading update in advance of announcing half-year results on 10
August 2010.

Trading performance

Trading in the first half has been in line with the Board's expectations. As
detailed in our Interim Management Statement on 10 May 2010, we expect that the
second half weighting of profits will be more pronounced than usual.

The Group continues to benefit from its exposure to international markets. The
Middle East construction and services businesses are performing well and have
improved their future workload since the year end. Recent new awards include a
multi-year highways maintenance contract in Dubai, where we are the exclusive
provider of planned and reactive maintenance services to the Dubai Roads and
Transport Authority.

As previously highlighted, the equipment services operation in the Gulf is
performing behind last year's exceptionally strong level, as it returns to a
more balanced hire: sale mix. However, we are encouraged by our recent entry
into Saudi Arabia and remain excited about the pipeline of opportunities in
this market. Elsewhere, Australia continues to benefit from a buoyant mining
and infrastructure sector, mitigating the challenging trading conditions
currently being experienced in several of our other international markets.

In the UK, the public sector is in a period of transition following the
election of the new coalition government. Our construction business is on track
to have a strong year having entered this year with a record future workload,
giving it good revenue visibility for the remainder of 2010 and 2011. Our
facilities management businesses which face the public sector have continued to
grow revenues, benefiting from the contracts won over the past eighteen months.
As previously indicated, several of these contracts have impacted performance
to date due to significant mobilisation and transition costs. We are well
advanced in taking the actions necessary to achieve planned levels of
profitability on these contracts. Consequently, we would anticipate that this
will drive an improvement in performance as the year progresses.

Whilst we are encouraged by some attractive new contracts, the UK private
sector environment continues to be competitive, impacting trading particularly
in the former specialist services businesses, where performance has
deteriorated and additional restructuring measures are being taken.

Outlook

Given the uncertainties in our markets, 2010 is a challenging year. However, we
are confident that through an improvement in second half performance we will
achieve the Board's expectations.

Looking forward, we have a significant international exposure and a future
workload1 of approximately £6 billion, despite uncertainties regarding the
impact of planned cuts in UK public sector spending. This affords the Group
strong visibility of around 90 per cent and 60 per cent of 2010 and 2011
anticipated2 revenues respectively. We remain confident in the long-term
prospects of the Group.
