Car park line marking: bay sizes, paint or thermoplastic, and costs
A common UK parking bay is 2.4 m by 4.8 m. Accessible bays add a hatched access zone, typically 1.2 m along the side and rear, following BS 8300-1 guidance. New-layout bay marking costs about £45–£120 per bay excluding VAT.

Bay sizes
Standard bays are commonly 2.4 m wide and 4.8 m long, with wider aisles where cars reverse out. Accessible bays and parent-and-child bays need extra space for doors and wheelchairs; your designer or BS 8300-1 guidance sets the details.
Paint or thermoplastic?
Thermoplastic is laid hot and lasts longer under traffic. Paint is cheaper for lightly used car parks or temporary layouts.
Costs
As a 2026 guide, about £45–£120 per bay on a new layout and £2–£10 per metre for lines, excluding VAT. Small jobs often have a minimum charge of around £500.
Speed humps
Asphalt speed humps with chevron markings typically cost about £800–£3,000 each excluding VAT, depending on width and profile.
Questions
How long does line marking last?
Paint a few years; thermoplastic often several years longer, depending on traffic.
Can you re-line our existing layout?
Yes, or redesign it to fit more bays or add accessible spaces.
