A letter from Sigma Financial Group typically lands long after you last heard from the original lender. That’s because Sigma is a UK debt purchaser — they buy portfolios of written-off consumer-credit accounts from banks, telecoms providers, utility suppliers and short-term lenders, and pursue you for the balance.
This guide covers who Sigma are, what they are legally allowed to do under the FCA’s CONC rules, the settlement-leverage point most people miss when dealing with a debt purchaser, and how an IVA can legally stop them and write off what you owe.
Who Sigma Financial Group are#
Sigma Financial Group is a UK debt-purchase business — bulk buyers of consumer-credit portfolios that the original lender has classified as bad debt. The portfolios they buy typically include credit-card accounts, personal loans, catalogue balances, mobile-phone contracts, utility arrears and short-term loans.
Sigma is regulated by the Financial Conduct Authority for consumer-credit collection activity. UK consumer-credit collectors are typically members of the Credit Services Association, and Sigma must follow the FCA’s Consumer Credit Sourcebook (CONC), the Consumer Credit Act 1974, and the terms of the original credit agreement.
The debt-purchaser business model has one feature that matters to you as a consumer: portfolios are bought at a deep discount to face value. Industry pricing for old, written-off consumer-credit portfolios is commonly in the 5-15% range — sometimes much less for very old debt. That means even a 60% settlement still represents a healthy multiple of what Sigma paid for the account. Settlement discounts of 30-60% are routine.
What Sigma can and cannot legally do#
Sigma are debt collectors, not bailiffs. They can:
- Write to you and call you on numbers held in the file
- Apply for a County Court Judgment if they believe the debt is enforceable
- After a CCJ, apply for an attachment of earnings, charging order on a property, or instruct High Court Enforcement Officers
- Sell the debt on to another debt purchaser
They cannot force entry, take goods without enforcement officers, threaten arrest (it’s a civil matter), continue contacting you after a written request that they stop, or add fees beyond what the original credit agreement allowed.
If Sigma isn't the only debt, an IVA combines every unsecured balance into one affordable monthly payment from £70. Interest stops, contact stops, and the unpaid balance is written off at the end.
Check if an IVA fits your situationStep 1 — confirm the debt is yours and is enforceable#
Before paying anything, send Sigma a CCA request under sections 77/78 of the Consumer Credit Act 1974. You have a statutory right to a copy of the original signed credit agreement, the statement of account, and proof of assignment from the original lender to Sigma. Enclose the £1 statutory fee.
Sigma have 12 working days plus a further 30 calendar days to comply. Until they do, the debt is legally unenforceable — they cannot lawfully use court action against you. Many bulk-purchased debts cannot be backed by the original signed agreement.
Step 2 — check whether the debt is statute-barred#
Most consumer debts in England and Wales become statute-barred under the Limitation Act 1980 once six years have passed since you last made a payment or acknowledged the debt in writing — provided no court action has started in that window. In Scotland the rule is similar but the period is five years, and a “prescribed” debt ceases to exist legally.
If the dates fit, write to Sigma stating that you consider the debt statute-barred. Do not pay anything, even a small “goodwill” amount, before checking dates — a single payment can reset the clock.
Step 3 — choose the route out#
If the debt is yours and enforceable:
- Discounted settlement — counter their first offer in writing. 30-60% off is normal; 70%+ off is achievable on very old or poorly documented debts.
- Affordable instalment plan based on the Standard Financial Statement.
- IVA if total unsecured debt is £5,000 or more across two or more creditors. The IVA legally stops Sigma and writes off the unpaid balance at the end of the 5-6 year term.
- Debt Relief Order if total debt is under £50,000 with very low spare income.
- Bankruptcy for severe situations.
Always confirm any agreement reached in writing with a clear “full and final” clause for settled accounts.
An IVA is often the cleanest answer to a Sigma debt when there's more than one creditor in the picture. The free 2-minute eligibility check is private and has no impact on your credit file.
Run the free IVA checkHow Sigma tend to pursue accounts#
- First letters often include a settlement-discount offer of 20-40% off the balance. Their pricing assumes negotiation — counter in writing.
- They use county-court bulk processing for litigation on accounts that are within the limitation period and have a clear paper trail.
- For homeowners, post-CCJ they often pursue a charging order rather than escalating to High Court Enforcement.
- Material decisions on settlement and litigation are made centrally — keep correspondence in writing and ask for everything to be confirmed by letter or email.
Common pitfalls when dealing with Sigma#
- Don’t ignore CCJ paperwork. A claim form sent to your address starts a 14-day acknowledgement-of-service timer; missing it produces a default judgment.
- Don’t accept the first settlement offer as their best price — the room is usually substantial.
- Don’t make a “goodwill” part-payment before checking statute-barred dates.
- Don’t share bank details over the phone without verifying the line through Sigma’s official channels.
Frequently asked questions#
Are Sigma bailiffs? No. Sigma are debt purchasers and collectors. They can write, call and instruct field agents, but cannot force entry or take goods.
How much will Sigma settle for? Discounts of 30-60% off the balance are common; 70%+ is achievable on older, poorly documented portfolios. Always counter-offer in writing.
Will an IVA include this debt? Yes — Sigma debt is unsecured and goes into an IVA like any other unsecured debt. Once approved, Sigma must stop contact on the included balance.
Is the debt statute-barred? If the last payment or written acknowledgement was more than six years ago in England and Wales (five in Scotland), and no court action has started, yes.
