Ofgem, Ofwat, and Ofcom are not doing enough to protect financially vulnerable customers, according to MPs who want regulators to coordinate more closely as household debt across essential services rises.
The House of Commons Public Accounts Committee said it lacks confidence that the regulators responsible for energy, water, and broadband are providing sufficient support to people struggling to pay their bills.
Consumer debt to energy and water companies totalled £7.2bn in March 2025, while regulators still lack a comprehensive view of an individual household’s debts across the three sectors.
The committee argues that this fragmentation limits the ability of companies and regulators to identify financial difficulty early enough to prevent arrears from becoming entrenched.
Its recommendations include greater data sharing, more proactive identification of customers requiring support, improved take-up of social tariffs, and a “tell us once” approach intended to stop people repeatedly providing the same sensitive information to different suppliers.
MPs also want discounted tariffs to become the default for the most financially vulnerable where practical and have proposed a central register covering communication, access, and other support needs.
Current take-up suggests a substantial gap between available schemes and the number of people who may qualify. Only 6% of water customers in England and Wales are on social tariffs, while fewer than 9% of eligible broadband customers receive equivalent support.
The committee also found that 13% of households have taken up energy and water assistance intended for people with additional communication, safety, or access requirements, although around half of households could potentially qualify.
The findings expose an operational weakness created by regulating essential services largely in separate vertical systems.
A household facing financial difficulty may have to deal independently with an energy supplier, water company, and broadband provider, each using different eligibility criteria, terminology, forms, digital systems, and evidence requirements.
Repeating personal and financial circumstances across several organisations can itself become a barrier to accessing help, particularly for customers dealing with illness, disability, bereavement, debt, or other difficult circumstances.
The committee also raised concerns about people becoming trapped in automated customer-service processes as suppliers make greater use of artificial-intelligence chatbots.
Automation can lower the cost of dealing with routine enquiries and provide support outside normal operating hours, but essential-service providers still need effective escalation where a customer’s circumstances cannot be handled through a standard digital pathway.
The regulatory issue therefore extends beyond whether a company technically offers a support scheme. Customers have to be able to identify the help, understand whether they qualify, communicate their needs, and complete the process before the protection has practical value.
Affordability pressure is also intersecting with a period of heavy infrastructure investment. Water, energy, and telecommunications networks require substantial capital to replace ageing assets, improve resilience, meet environmental requirements, and expand capacity.
Ofwat provisionally approved up to £3.4bn of additional investment across 13 water companies in August, including projects related to water quality, housing, and data-centre capacity.
Some of that expenditure can ultimately affect bills. The more essential-service costs rise, the more important it becomes for affordability systems to identify customers before serious debt accumulates.
The committee’s proposed central register would attempt to solve one part of that fragmentation by allowing relevant support needs to be recognised across sectors.
Such a system would bring its own governance requirements. Data relating to financial vulnerability, health, disability, and access needs can be highly sensitive, requiring clear rules around consent, accuracy, retention, security, and who is entitled to view or update information.
MPs also want the government to clarify plans for a statutory water ombudsman and for an organisation responsible for providing free advice to telecommunications customers.
Sir Geoffrey Clifton-Brown, chair of the committee, said consumers should not be allowed to drift into debt through poor communication and coordination between suppliers, regulators, and government.
The regulators and government will now be expected to respond to the committee’s recommendations. The central test will be whether separate sector protections can be converted into a more coherent system that identifies vulnerability earlier and makes support easier to access before arrears become severe.
