Electoral Roll and Credit Scores: Why It Matters So Much

The electoral register — commonly referred to as the electoral roll — plays a significant but often misunderstood role in the UK credit system. Credit reference agencies (CRAs) are legally entitled to purchase copies of the full electoral register and use the data it contains for credit checking and identity verification purposes. This article explains how that process works, what the legal framework looks like, and where common confusion arises.

This guide covers the mechanisms by which electoral data reaches credit reference agencies, the timelines involved, the legal basis for the system, and the position of individuals who are not registered or who are not eligible to register.

• The three main consumer credit reference agencies in the UK — Experian, Equifax, and TransUnion (formerly Callcredit) — purchase copies of the full electoral register from local Electoral Registration Officers. They use this data to confirm identity, verify addresses, and assess address consistency when a lender requests a credit check. The legal authority for this sits primarily in Regulation 114 of the Representation of the People (England and Wales) Regulations 2001, with equivalent provisions covering Scotland and Northern Ireland.
• It is the full register that CRAs access — not the "open register" (formerly the edited register). Opting out of the open register does not prevent CRAs from seeing your electoral data. Being registered on the full electoral register at a UK address is one of the ways lenders verify who you are and where you live.
• The specific way each CRA uses electoral data within its proprietary scoring models is not publicly disclosed. What is publicly known is that CRAs treat electoral registration as a factor in their processes. The exact weighting or numerical impact on any individual credit score is not verifiable from official sources.

Electoral registers in the UK are compiled locally. Each local authority area has an Electoral Registration Officer (ERO) responsible for maintaining the register of eligible voters. Credit reference agencies must purchase the register separately from each local authority area.

Once purchased, CRAs use electoral register data for several documented purposes: confirming the identity and address of credit applicants, checking that addresses provided on applications are correct, assessing address consistency and assisting with identity matching through the length of registration at a current address, and assisting with anti-money laundering compliance obligations under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017.

When a person applies for credit — a mortgage, credit card, loan, or similar product — the lender will typically request information from one or more CRAs. The CRA's records will include, among other things, any electoral register data it holds for that person. This forms part of the information the lender uses to make a decision, alongside other data such as payment history and existing credit commitments.

CRAs are authorised for relevant activities by the Financial Conduct Authority (FCA) under the Financial Services and Markets Act 2000, while data protection compliance is overseen by the Information Commissioner's Office (ICO). CRAs must hold appropriate permissions under FSMA to operate as credit reference agencies. To be eligible to purchase the full electoral register, a CRA must also be registered under Part III of the Consumer Credit Act 1974 and must be carrying on the business of providing credit reference services. Electoral Registration Officers have the right to require evidence that an agency meets this definition before releasing register data.

The Annual Canvass and Register Publication

The annual canvass — the process by which EROs check and update their registers — runs from approximately July or August through to November each year. The revised register is published by 1 December. This deadline applies even if 1 December falls on a weekend or bank holiday. Publication can be delayed until up to 1 February the following year if an election is held between 1 July and 1 December.

Monthly Rolling Registration Updates

Outside the annual canvass period, the electoral register is updated monthly through rolling registration. These monthly updates are published on the first working day of each month, except during October and November when the annual canvass is underway. Cut-off dates for applications to appear in a given monthly update are typically three to four weeks before the publication date. For example, applications received by 11 December would typically appear in the 2 January update, and applications received by 23 January would typically appear in the 1 February update.

How Quickly CRAs Reflect Changes

According to published guidance, electoral details typically appear on credit reports within 30 days of the register being published. In practice, this may vary by CRA — some sources indicate updates can take anywhere from one week to several weeks after a register update is published. During the annual canvass period (August to November), electoral details may not appear on credit reports until the revised register is published on or around 1 December.

Statutory Fees for Register Purchases

The fees CRAs pay for electoral register data are set by statute. In England and Wales, the fee for a data-format copy is £20 plus £1.50 per 1,000 entries (or part thereof). For a printed-format copy, the fee is £10 plus £5 per 1,000 entries (or part thereof). These fees have not been changed since they were introduced in 2002. Equivalent fee structures exist in Scotland and Northern Ireland. EROs may also charge for postage and packing. The Association of Electoral Administrators has called for these fees to be reviewed, noting that they have remained unchanged for over two decades.

Consumer Access to Credit Files

Under Section 158 of the Consumer Credit Act 1974, consumers have a statutory right to access their credit reference file. While the Act historically referenced a £2 fee, current practice under UK GDPR means statutory credit reports are provided free of charge. Section 157 separately requires a creditor to disclose which CRA was consulted if a credit application is refused based on information obtained from that agency.

"I opted out of the open register, so CRAs can't see my data."

This is incorrect. The open register (formerly the edited register) is a separate product that anyone can purchase for general purposes such as marketing. Opting out of the open register is unrelated to CRA access. Credit reference agencies purchase the full electoral register under specific legal authority, and opting out of the open register does not affect this.

"Being on the electoral roll boosts my credit score by a specific number of points."

The exact numerical impact of electoral registration on any credit score is not publicly disclosed by CRAs. Each agency uses proprietary scoring models, and the specific weighting given to electoral data within those models is commercially confidential. Claims of specific point increases that appear in general financial commentary are not verifiable from official CRA sources.

"If I'm not on the electoral roll, I'll automatically be refused credit."

Lender policies vary. In most cases, lenders use electoral data as one element in verifying identity and address. Some lenders may accept alternative proof of address — such as a Council Tax bill, utility bill, tenancy agreement, mortgage details, or driving licence — if electoral registration data is not available. There is no universal rule requiring lenders to refuse credit solely on the basis of electoral roll absence.

"The electoral roll is just about voting — it has nothing to do with credit."

While the primary purpose of the electoral register is to facilitate elections, the full register is also a legally authorised source of identity and address data for credit reference purposes. This dual role is established in legislation.

Several groups of people interact with this system differently from the general population.

• Anonymous Registration: Individuals who are registered anonymously on the electoral register — for example, for safety reasons — will not have their electoral data visible to credit reference agencies. Anonymous registration entries are only accessible to registration officers and elections staff.
• Ineligible to Vote: Individuals who are not eligible to vote in the UK, such as certain foreign nationals, cannot register on the electoral roll. They therefore cannot have electoral data on their credit files. According to CRA guidance, such individuals can add a "Notice of Correction" to their credit file explaining their ineligibility to register. This notice is then visible to lenders when they request a credit check.
• Under 16s: Where voting age is 16 — as applies in Scotland and Wales for certain elections — individuals under 16 who have registered in advance of reaching voting age have their data protected and it is not disclosed to credit reference agencies.
• No Fixed Address: Individuals without a regular or permanent UK address may find that their electoral data is not processed automatically by CRAs. According to published CRA guidance, in most cases these individuals can contact a CRA to have electoral information added manually, provided they can supply proof of registration.
• Guernsey Residents: Residents of Guernsey are in a distinct position: CRAs cannot access Guernsey electoral data automatically. According to published guidance, Guernsey electoral information can usually be added manually if proof of registration is provided to the CRA.
• Name Changes: If an individual changes their name or address on the electoral register, there may be a temporary disruption in how electoral roll data matches on credit files. CRAs may still hold previous information for context, but automated matching may be affected until records are updated through the next register publication cycle.

The electoral register is one of the foundational data sources that CRAs use to build credit reference files. Registration on the full electoral register provides a data point that CRAs can use for identity confirmation and address verification. The length of time a person has been registered at their current address may also be visible to CRAs, and published guidance from agencies indicates that address consistency is used as part of address verification and fraud prevention rather than as a measure of personal reliability — though the precise weight given to it is not publicly known.

The system operates on a cycle: the annual canvass produces a revised register each December, with monthly rolling updates filling in the gaps throughout the rest of the year. CRAs purchase these registers and updates, and integrate the data into their systems. When someone applies for credit, the lender queries the CRA, and the CRA's response includes whatever electoral data it holds for that applicant.

The completeness of the electoral register varies. According to Electoral Commission analysis, register completeness was estimated at 86% in Great Britain (as of 2023) and 83% in Northern Ireland. Registration rates differ significantly by age group: estimates based on December 2022 registers suggest rates of approximately 60% among those aged 18–19, approximately 74% among those aged 25–34, and approximately 96% among those aged over 65. An estimated 8 million eligible voters in the UK are not registered. These figures are estimates and should be treated as indicative rather than precise. They are subject to margin of error and variation by local authority.

For individuals who are not on the electoral register — whether by choice, circumstance, or ineligibility — the practical effect is that CRAs will not hold electoral data for them. In most cases, lenders may request alternative documentation to verify identity and address, but lender policies on this point are not uniform.

• The full electoral register is a legally authorised data source used by the UK's three main credit reference agencies for identity verification, address checking, and anti-money laundering compliance.
• CRA access to the full register is entirely separate from the open register, and opting out of the open register does not affect it.
• Electoral data reaches CRAs through a combination of annual register publication (by 1 December each year) and monthly rolling updates.
• The specific role electoral data plays within proprietary credit scoring models is not publicly disclosed by any CRA.
• Individuals who cannot appear on the electoral register — due to ineligibility, anonymous registration, or other circumstances — may face additional steps in the credit-checking process, with lender responses varying on a case-by-case basis.
