Registering to vote on the electoral roll is the single most impactful free action you can take to improve your UK credit score. Yet millions of UK adults aren't registered, and many who are haven't updated their details when moving address.
Why Credit Reference Agencies Use the Electoral Roll
UK credit reference agencies — Experian, Equifax, and TransUnion — use the electoral register as a primary tool for identity and address verification. When a lender runs a credit check, matching your details against the electoral register confirms who you are and where you live. Being absent from the register creates uncertainty, which translates to a lower score.
- •CRAs cross-reference your application details with the electoral register
- •Being registered confirms your identity and address stability
- •Registered for 2+ years at same address: strongest positive signal
- •Recently moved: update registration immediately after moving
- •Not registered at all: significant negative factor for most lenders
How Much Difference Does It Make?
Being registered on the electoral roll can improve your credit score by up to 50 points on the Experian scale, according to the agency's own guidance. The difference is most significant for people with limited credit history (young adults, new UK residents, those who have recently moved). For established credit profiles, it's still a meaningful factor but not the only one.
- •Up to 50 Experian points for electoral roll registration
- •Most significant for: thin credit files, young adults, recent movers
- •Experian specifically cites electoral roll as a key factor
- •Not registered = significant gap in identity verification
- •New UK residents: electoral registration + CRA link is especially important
Does being on the electoral roll guarantee a better credit score?+
No — it's one factor among many. But it's the easiest free action to take, and being absent from the register is consistently cited by lenders as a flag. It's the foundation, not the whole building.
How to Register
Registering takes under 5 minutes at gov.uk/register-to-vote. You'll need your National Insurance number and passport (or other ID). You can also register via your local council's website.
- •Visit: gov.uk/register-to-vote
- •Need: National Insurance number and either passport or driving licence
- •Takes 3-5 minutes
- •Confirm registration via email or post
- •You can register even if you don't intend to vote — it's separate from actual voting
Keeping Your Registration Updated

- •Update via gov.uk/register-to-vote whenever you move
- •Also update your address with all banks and credit accounts
- •Annual canvass letter from your council: respond promptly
- •Check all three CRAs show your correct current address
