02033733588: Verify oneSource Calls and Your Options

MoneyNerd introduces enquiries to The Debt Advice Service and may receive a referral fee. For free, independent guidance and help finding a debt adviser, visit MoneyHelper.

This information and enquiry service is not a full financial assessment or a guarantee of suitability or debt write-off. Debt solutions are not suitable for everyone. Fees may apply, and your credit record and assets may be affected. Get advice on your circumstances before choosing a solution.

0203 373 3588 is published on the official oneSource Debt Resolution Services website. However, a number displayed on your phone cannot prove who is calling, because caller ID can be spoofed.

This guide explains how to verify a call, check the debt and ask for help before agreeing to payment.

If these calls are worrying you, you can ask for written information and seek free debt advice.

Your next step depends on the debt, the enforcement stage and what you can afford.

Who called?

oneSource provides local authority debt collection and enforcement services. Its official contact page lists 0203 373 3588. Check the notice and the instructing council as well as the caller’s identity.

Council Tax, business rates and traffic debts follow different recovery procedures. A call alone does not establish which powers or fees apply.

In the sections below, we will explain more about these calls and how you might be able to deal with them better. If you have received debt letters from the One Source Debt Collection already, you can discover ways to respond to these letters in our special One Source Debt Guide.

Start by checking the notice and the contact details independently.

Why was I contacted?

Bailiffs normally must send a Notice of Enforcement before taking control of goods. Under the rules applying from 1 May 2026, the usual minimum is 14 clear days, with a longer period in specified debt-advice circumstances; a court can shorten the notice period. Do not confuse this advance notice with a promise of the exact time of a later visit.

A verified call may concern payment, an affordable arrangement or information about your circumstances. Ask for the debt and enforcement reference in writing.

Ask oneSource and the instructing council for a breakdown of the debt, the authority for enforcement and any fees. Disputing the debt does not automatically suspend enforcement or a statutory deadline, so get urgent debt advice if a visit is threatened.

How the introduction works

The Debt Advice Service can discuss your circumstances and explain available options, including their benefits, costs and risks.

Options depend on your circumstances. You decide whether to proceed.

Can I ignore their calls?

You do not have to discuss a debt on an unexpected call. Contact oneSource through its official website or ask the instructing council to confirm the referral. Act promptly on genuine notices and ask about an affordable arrangement.

You should also know that bailiffs charge fees that get added to your debt. Trying to arrange a resolution faster could save you money.

Here are some of the fees bailiffs can charge during a debt collection process.

How do I stop them from contacting me?

You can ask oneSource to use a suitable contact method and explain any health, disability or language needs. Enforcement agents must not use threats or harassment. For council enforcement complaints, start with the service and instructing council; the Financial Ombudsman is not the usual route for council tax or traffic enforcement.

Vulnerability can require extra support and affect how enforcement is carried out. It does not automatically stop every call or visit, and being a single parent or not speaking English does not by itself cancel the debt.

Tell oneSource and the council what support you need and ask them to pause action while they consider it. Seek free debt advice urgently. Keep evidence of the request and any reply.
