Utilities and energy customer service outsourcing

Bills explained. Complaints resolved. Customers kept.

ATM Group provides outsourced customer service, billing support, complaints handling and retention for utilities, energy, home services and infrastructure businesses in the UK and Europe. We run inbound and outbound customer care, billing and payment queries, complaints and escalations, engineer appointment booking, save and retention activity and peak-period support as one accountable operation, backed by analytics, quality monitoring and AI-assisted optimisation across our delivery centres in the UK, the Netherlands and South Africa. Our approach is proven in the closest comparable environment: on a telecoms retention programme, retention improved by 10% while customer satisfaction rose from 7.2 to 8.2.

What does ATM handle for utilities and energy suppliers?

The parts of the customer operation that decide whether a supplier is trusted or complained about:

• Inbound and outbound customer service: account queries, moves, meter and tariff questions, proactive contact around changes.
• Billing and payment support: bill explanations, direct debit reviews, payment plans and arrears conversations handled with care.
• Complaints handling and escalations: complaints resolved to your regulatory timelines, with the records you need if a case goes to the ombudsman.
• Engineer and appointment booking: scheduling, rescheduling and confirmation for field and home visits.
• Retention and save activity: proactive and reactive journeys that keep customers who were about to leave.
• Peak and surge support: planned capacity for price cap changes, cold snaps, outages and campaign spikes.
• Back-office operations and data insight: the processing behind the contact, plus the analysis of why customers call.

Each programme starts with your customer journey. We map contact drivers, agree workflows and KPIs, then add knowledge, coaching and testing before we scale.

How do you handle billing queries and complaints at volume without service dropping?

By treating volume as a design problem rather than a headcount problem. Advisors are multi-skilled across account support, billing and complaints, so a customer is helped once rather than transferred. Contact-driver analysis tells us which bill formats, letters and journeys are generating avoidable calls, and that insight goes back to you as a monthly change list. Quality monitoring, calibrated with your team, checks the conversations that matter most: vulnerability, disputed charges and anything inside the eight-week ombudsman window. Reporting ties operational measures such as first-contact resolution and repeat contact to the outcomes you answer for, including complaint volumes and customer satisfaction.

Can you help us reduce churn and win customers back?

Yes. Retention conversations usually start inside service conversations: a bill that looks wrong, a missed appointment, a complaint that dragged on. Our retention and save teams work alongside the service team, using speech and text analytics to find the real drivers of churn and feeding frontline insight back into offers, timing and journey changes. On a telecoms retention programme, that model handled more than 100,000 peak-period interactions with 250 multi-skilled advisors while lifting both retention and satisfaction. On a large-scale migration and upgrade programme for another telecommunications provider, the same evidence-led approach reduced churn by 15% across more than 250,000 customer migrations, with 6,500+ upgrades delivered.

Do you support home services and infrastructure businesses too?

Yes. Engineer booking, account and billing support, parts and technical queries and retention are the same operating problem whether the customer is an energy account holder, a boiler-care customer or a trade partner. On an after-sales operation for a global appliance brand, our team handled engineer appointment booking, parts ordering, technical support and closure validation for both trade partners and end customers. On a three-month inbound proof of concept for an appointment-based service brand, we tested offering appointment bookings during live inbound contacts without adding handling time.

What proof can you show?

Two recent programmes for large telecommunications providers, the sector closest to utilities in volume, billing complexity and churn risk:

• Retention programme: retention up 10%, customer satisfaction up from 7.2 to 8.2, more than 100,000 peak-period interactions, 250 advisors multi-skilled for flexible resourcing.
• Transformation and migration at scale: churn down 15%, more than 250,000 migrations supported, 1,300+ customers retained, 6,500+ upgrades delivered, 100+ trials run to refine journeys.

In 2026 ATM Group was named a finalist in three categories at the UK National Contact Centre Awards, run by the CCMA, and took Silver for Best Apprenticeship Programme. More client successes, awards and accreditations are on our proof page.

How do you use technology without losing the human touch?

Where it improves the outcome, and never as a substitute for a trained advisor on a difficult call. Our Digital DX service and ATM One interaction intelligence platform add agent assist and next-best-action prompts inside the conversation, automated quality monitoring across every contact rather than a sample, and speech and text analytics that surface the root causes behind billing and complaint volumes. Virtual agents take the simple, repeatable contacts such as meter readings and appointment confirmations, so people are free for the conversations that need judgement.

Where do you deliver from, and how quickly can you start?

Across the UK (Leicester, Coventry and Stockport), the Netherlands (Sittard and Heerlen) and South Africa (Cape Town), with partner coverage in Turkey, and multilingual delivery in 10+ languages where programmes need it. With 20+ years’ experience and 1,000+ active advisors, we can stand up trained capacity for a known date such as a price cap change and flex it across sites afterwards. Where appropriate we start with a pilot or a “prove to move” programme: a defined scope, agreed KPIs and the evidence to expand only once the uplift is demonstrated.
