Delivering for customers
in a changing climate
Our teams work around the clock delivering a
brilliant service for our customers to keep
clean water flowing into homes and
businesses, and take away and recycle waste
water. Quite rightly, our customers expect this
service to continue 24/7, and I’m proud of the
work we’ve achieved to minimise the impact of
climate change experienced by our customers
this year.
We’ve hit or exceeded our targets on c.80% of
our performance commitments, earning an
outperformance reward of £53 million, despite
the weather challenges faced this year which
have impacted a number of measures. As we
look ahead to AMP8, when our comparative
position will be even more important, our whole
business is focused on pushing our
performance even further.
Keeping clean water flowing
We have invested a significant amount of time
and resource into strengthening the resilience
of our water networks over the past few years.
We’ve brought more assets online to
strengthen our network, improved flexibility to
enable us to get water to the right places at the
right time, and created an in-house Network
Response Team – 135 people and 42 tankers
dedicated to getting our customers back on
supply as quickly as possible. All of which
really paid off this year.
The summer of 2022 was one of the hottest and
driest since records began. At its peak, we
were producing an extra 450 million litres of
clean water a day. The resilience ofour
network, combined with the incredible support
from our customers in response to our
extensive demand management campaigns,
meant we were able to keep the water flowing,
navigating the summer conditions with no
enforced Temporary Usage Bans (‘TUBs’, also
known as hosepipe bans).
In common with many other companies, we’re
also feeling the effects of climate change in
winter. In December 2022, our region
experienced a sharp cold snap followed by a
rapid thaw. These temperature swings can
have a severe impact on our pipes, causing a
higher number of bursts. The last time we
experienced such an event was the Beast from
the East in 2018 and I’m really pleased that the
work we’ve done since then meant that the
interruption to our customers’ supply was
reduced by 93%.
Never has it been clearer that water is a
precious resource and one that we all need to
take care of, and I’m delighted with the
sustained progress on our leakage journey,
hitting our target for the eleventh year out of
the last twelve, despite the significantly higher
number of bursts we’ve faced following a
challenging winter. We’re fixing over 3,000
leaks a month and we’ve reduced the time it
takes for us to reach a leak by 30% since 2020.
We’ve also accelerated our meter roll-out,
installing over 100,000 meters this year alone,
taking our metering coverage on household
customers to 61%. Alongside reducing bills for
many of our customers, this also gives us
much greater visibility and insight into our
network. This is especially the case for smart
meters, which we’re rolling out in Coventry and
Warwickshire and through which we have
already been able to collect valuable data on
consumption and other trends. Given the
success of our smart meter campaign, I was
particularly pleased to receive approval from
Ofwat to accelerate the roll-out of an additional
250,000 meters ahead of AMP8.
Our leakage rate is better than the average for
Europe, but we know that we can, and must, go
further. We have committed to reducing
leakage by 50% by 2045 (from a three-year
rolling average baseline set in 2019/20) and the
work we’re doing now places us firmly on track
to achieve that goal.
Focused on waste to create
abetterenvironment
We have once again met 100% of our environmental
measures and are highly confident that we
will achieve the highest-possible 4* rating
in our annual Environmental Performance
Assessment (‘EPA’) for 2022 by the EA, making
it four consecutive years – something no other
company has ever achieved.
We are proud of our total pollutions
performance, which has seen a year-on-year
improvement of 5.4%, resulting in our best ever
year on serious pollutions. While we’re proud of
our continued improvements in this space, we
recognise that any pollution is unacceptable and
we are striving to halve our total pollutions by
2025. As part of this ambition, we are focused
on reducing asset failure through a rigorous
maintenance programme and improved event
response times, supported by the ongoing
installation of 40,000 sewer sensors and the
establishment of our new in-house Waste
Network Response Team, inspired by learnings
in our water business.
One cause of pollutions is blockages in our
network, and we’ve been successful in driving
these down by 20% compared with the end of
AMP6 through a relentless focus on data,
sewer cleansing and customer education on
the causes and impact of sewer misuse.
While we have met a number of our key waste
measures, we have incurred a penalty this year
on external sewer flooding, where we missed
astretching target that reflects our historical
sector-leading performance. The extreme
fluctuations in rainfall we’ve experienced this
year have been a key driver of our
performance, with our region experiencing
only 14% less rainfall than average despite the
prolonged dry summer. We have also
experienced a deterioration in some of our key
performance drivers and are reviewing our
delivery model on our waste infrastructure,
including the insourcing of critical teams, such
as planning and scheduling. We expect to
continue to be a strong performer on this
measure compared with the sector, but our
customers rightly expect more of us and we
are working hard to drive the required
improvements to meet our target.
There for our customers when they
need us most
We have delivered c.90% of our customer
performance commitments, and I am
particularly pleased to see a 16% reduction in
customer complaints compared with last year
as we continue to improve our service offering.
We continue to take steps forward in our
Customer Measure of Experience (‘C-MeX’)
and Developer Measure of Experience
(‘D-MeX’) journeys to ensure we can answer
our customers’ queries at point of contact, and
keep customers informed.
This year we launched anew ‘Intelligent
Kickouts’ process, which usescustomers’
historical consumption data to track
andidentify changes in their water usage and
proactively engage with them, before their bill
is issued. We have designed 30 different
communication journeys to ensure customers
receive the right information, at the right time,
in the right way. In the six months since we
launched our new process, we have proactively
engaged with almost 10,000 customers,
helping them to manage their consumption,
reducing contacts from customers and
identifying an additional 14,000 litres of
private-side leakage a day, with zero
complaints from customers.
Of course, alongside delivering the best
service possible, we want to be there for our
customers when they need us most, and right
now many are struggling with overwhelming
pressures associated with the increased cost
of living. Last year, we announced a package of
financial support worth £30 million to allow us
to support 315,000 customers – the biggest
support scheme any company in our sector
hasever offered.
We’re proud to continue to offer one of the
lowest bills in the country, at an average of
£1.15 per day, and we’ve committed to growing
our bill by less than inflation for 2023/24, as we
don’t want anybody to fear their water bill.
Through our affordability schemes, we can
offer any customer who needs it up to 90%
discount off their bill, taking the water bill off
their worry list. We are financially supporting
over 237,000 customers and are on track to
help 315,000 customers by 2025. While we
don’t wish to see anybody in a situation where
they need our help, we take comfort in knowing
that we still have the capacity to support many
more should they need it.
But financial support is a short-term solution,
and we want to go much further, to make a
genuine difference in the communities we live
and work in. That’s why we announced our
Societal Strategy in November 2022 our
commitment to help support 100,000 people
out of poverty by 2032. This is a huge
commitment and one we don’t take lightly, and
we have robust plans in place to deliver this
support. You can read more about our plans
