Key facts
- Mark Arnull has been Reform UK Leader of West Northamptonshire Council since 2025, chairing the cabinet and setting council policy.
- UK councils handle council tax, social housing, planning and licensing, adult and children's social care, waste and recycling collection, local roads, and (outside London) local schools. Reserved matters — benefits, immigration, tax, and the NHS's national policy — go to central government or your MP instead.
- Identify yourself as a resident: full name, home address, and postcode, so staff can confirm you live in the council's area. For a ward-specific issue, your own ward councillor (found via the council's website) will usually get a faster reply than the Leader.
- Post to a council leader is not free — a normal Royal Mail stamp applies.
- PostPal prints your letter and posts it via Royal Mail the next business day for £4 — no printer, envelope, or stamp needed.

Common questions
What is Mark Arnull's mailing address?
Councillor Mark Arnull, Leader of the Council, One Angel Square, 4 Angel Street, Northampton, NN1 1ED.
Should I write to the council Leader or my local councillor?
For a council-wide policy question, write to Arnull as Leader. For something specific to your street or estate (a pothole, a planning application next door, a bin collection issue), your own ward councillor is usually faster — find them via West Northamptonshire Council's website and post to the same civic address, marked for their attention.
Do I need a stamp to write to Arnull?
Yes — post to a council leader takes normal postage; there's no free-post rule for UK local government. If you'd rather skip the stamp and printer entirely, PostPal prints and posts your letter for £4 flat.
Do I have to live in West Northamptonshire's area to write to Arnull?
No, but casework is normally only taken up for residents. If you live outside the council's boundary, your own local council is the right first contact — or write to Arnull specifically about a policy that affects you as a visitor, worker, or business owner locally.
Will Mark Arnull actually read my letter?
Constituent post is logged by council office staff, and issues tied to an upcoming cabinet decision get flagged directly. Include your return address — PostPal prints yours automatically — so a reply has somewhere to go.
