Hertfordshire goes to the polls on Thursday, May 2 – but only eligible, registered voters can take part in the elections.

Voters must also show an accepted form of photo ID if they want to have their say at the ballot box.

Polling stations will open throughout the county for the Hertfordshire Police and Crime Commissioner (PCC) election.

Some voters will also get to choose who represents them on district and borough councils, with 159 seats due for election across Broxbourne, North Herts, St Albans, Stevenage, Three Rivers, Watford and Welwyn Hatfield, plus any by-elections.

Voters who are already registered do not need to re-register, unless they have had a change of circumstances – such as a new house or a name change.

Residents yet to register have until 11.59pm on Tuesday, April 16 if they want to take part.

Who is eligible to vote in Hertfordshire?

You must be registered at an address in the area you want to vote in.

For the elections taking place on Thursday, May 2, you must be either:

• a British citizen,
• an Irish citizen,
• a citizen of another European Union (EU) country, or
• a "qualifying commonwealth" citizen – which includes people from the Channel Islands, the Isle of Man, British overseas territories, Australia, Bangladesh, Canada, Jamaica, Malaysia, New Zealand, Pakistan, Singapore, and others.

Eligible university students can vote in either or both their "home" and "university" areas for the polls on May 2, as long as their addresses are in different council areas for the local elections and different policing areas for the PCC election – so as not to vote in the same poll twice.

Do I need to show ID?

Yes, you will need to show a form of accepted photo ID when you go to vote.

You do not need to bring your poll card with you.

Accepted photo ID includes your passport, a driving licence from the British Isles or EU, blue badge, older person's or disabled person's bus pass, a London Freedom Pass or Oyster 60+ card, a Defence Identity Card (Ministry of Defence Form 90), or another photo ID bearing the PASS (National Proof of Age Standards Scheme) hologram.

The 18+ Student Oyster photocard is not an accepted photo ID.

If you don't have an accepted form of photo, you can apply for a Voter Authority Certificate.

You will need a recent, digital photo of yourself.

You will be asked for your National Insurance number, but you can still apply if you have other documents to prove your identity instead.
