The UK Customer Satisfaction Index 2026 (July edition) puts banks and building societies at the top for the first time, with a sector score of 82.0 out of 100, while the national average edged up to 78.3. For contact centre leaders the message is plain: steady investment in training, technology and better support journeys is now beating retail’s long-held lead.

What follows is a short read of the results, why banking moved ahead, and what London’s contact centre and CX leaders can take from it before the next edition lands.

What did the UK Customer Satisfaction Index 2026 show?

The UK Customer Satisfaction Index (UKCSI) is published twice a year by the Institute of Customer Service. The July 2026 edition draws on more than 15,000 UK consumers and 59,500 customer experiences, scoring 277 organisations across 13 sectors.

• National score: 78.3 out of 100, up 1 point on July 2025 and 0.1 points on January 2026.
• Top sector: banks and building societies on 82.0, the first time the sector has led the index.
• Retail: non-food retail scored 81 and food retail 80.6. Retail had held the top spot since the index began in 2008, as Retail Gazette reported.
• Top organisations: Nationwide Building Society on 87.3, John Lewis on 87.1 and first direct on 86.0.
• Broad progress: six sectors improved by more than a point on a year earlier.

The Institute also found that customers now place more weight on good value, competitive pricing, product and service quality, and ease of doing business. In a tighter economy, people notice effort and they notice cost.

Why have banks overtaken retail for customer satisfaction?

The Institute of Customer Service credited banks’ gains to greater investment in training, technology and customer retention, and pointed to the Financial Conduct Authority’s Consumer Duty, which came into force in 2023. Its chief executive, Jo Causon, put it simply: “Regaining trust has been paramount.”

The Consumer Duty matters here because it pushed financial services firms to look hard at support journeys, not just sales. The FCA’s review of the consumer support outcome, last updated in July 2026, is a useful checklist for any contact centre. It praised firms that:

• used customer journey mapping to find and remove “sludge” from their processes
• routed bereavement queries from webchat straight to a human adviser
• flagged vulnerability keywords so those customers reached a priority queue

It was equally clear about weaknesses. Support after the sale was often weaker than before it, with longer waits for customers trying to cancel or downgrade. Some firms leaned on transactional measures such as contact rates and wait times, and 13% of firms surveyed carried out no quality assurance on their support channels at all.

Put together, the regulator asked banks to fix the parts of the journey customers find hardest, and the index suggests customers have noticed.

What does this mean for contact centre leaders outside financial services?

You do not need a regulator to borrow the playbook. Four lessons travel well to retail, utilities, travel, insurance and the public-facing side of almost any business.

Measure outcomes, not just speed

Average handle time and service levels still matter, but they say little about whether the customer’s problem went away. Pair them with measures of resolution, repeat contact and effort, and review a sample of real conversations every week.

Make leaving as easy as joining

The FCA’s test is that switching out of a product should be at least as easy as buying it. Walk your own cancellation, complaint and downgrade journeys. If they take longer than your sales journey, customers feel it and so will your score.

Train advisers to own difficult moments

Training was one of the drivers the Institute named. Bereavement, financial difficulty and complaints are where trust is won or lost, and they rarely fit a script. Advisers need the confidence and the authority to resolve them.

Decide where automation stops

Digital channels and AI can take a great deal of routine work, but the best-practice examples above route sensitive contacts to people quickly. Write down where that line sits in your operation, and test it with real journeys. Our earlier piece on AI governance in contact centres covers the oversight side.

Why does this matter for London’s contact centres?

LCCF research puts the number of contact centres in London and the South East at around 600, with roughly 78,000 seats between them.

That density is an advantage. The sector now leading the index and the sectors chasing it can sit a few streets apart, and many London leaders face the same pressures: rising costs, tougher customer expectations and the question of where AI fits. Our recent planning brief on the London Living Wage looks at the cost side.

The quickest way to learn what moved a bank’s score is to ask the people who did it.

How can London leaders learn from the sectors that are improving?

London Contact Centre Forum (LCCF), part of the Contact Centre Forum network, exists for exactly this kind of cross-sector conversation. The network was built by Jane Thomas through the South West, Northern and Scottish forums, and London now has a home of its own.

Members compare notes in a few practical ways:

• Forum on Tour: half-day visits to leading contact centres, with speakers and best practice you can see working.
• Friday Update: 30 minutes every Friday at 11am with colleagues across the network on whatever is topical that week.
• User groups: monthly virtual sessions for operations, training, planning, HR and team leaders.
• Roundtables and events: the next in-person dates are Making CX Work: Connecting People, Process and AI on 26 November 2026, the Operational Excellence 2027 Challenges Workshop on 10 December 2026, and Showcase UK Excellence on 25 February 2027.

Details of every event are on the London Contact Centre Forum page, and wider reading sits in our news and updates.

Frequently asked questions

What is the UK Customer Satisfaction Index?

The UK Customer Satisfaction Index, or UKCSI, is a national measure of customer satisfaction published twice a year by the Institute of Customer Service. The July 2026 edition surveyed more than 15,000 UK consumers about 59,500 experiences and scored 277 organisations across 13 sectors.

What was the UK Customer Satisfaction Index score in July 2026?

The national UKCSI score in July 2026 was 78.3 out of 100. That is 1 point higher than July 2025 and 0.1 points higher than January 2026. Banks and building societies led all sectors on 82.0, ahead of non-food retail on 81 and food retail on 80.6.

Which organisation topped the UKCSI in July 2026?

Nationwide Building Society was the highest-rated organisation, scoring 87.3 out of 100. John Lewis was the top retailer on 87.1, and first direct scored 86.0. It was the first time banks and building societies had overtaken retail as the leading sector since the index began in 2008.

How does the Consumer Duty affect contact centres?

The FCA’s Consumer Duty expects regulated firms to give customers support that meets their needs throughout the relationship, not just at the point of sale. For contact centres, that means fair access to help, no unnecessary barriers to cancelling or complaining, proper care for vulnerable customers and quality assurance that checks real outcomes.
