About us · Est. 1994
Precision on every surface.
On-Line Roadmarking Ltd are specialists in every aspect of ground marking. We take an old-fashioned pride in the quality of our lines, because a marking is a safety device, and it has to be right first time.
No job is too large or too small. From a single disabled bay to a full logistics-yard scheme, we complete every project on time, on budget and to a standard we are happy to photograph, batch-record and hand over. Our materials are chosen for the surface and the weather it will face, not for the margin on the tin.
- NVQ Level 2 qualified operatives, CSCS-carded, SSSTS-supervised
- Markings dimensioned to TSRGD and performance-tested to BS EN 1436
- Night, weekend and term-time programming around your operation
- Photographic handover records and material batch data as standard
How we work · 4 steps
Measured. Specified. Marked. Proven.
Survey & measure
A site visit or desktop review, then a CAD layout with bay counts, dimensions and materials stated explicitly. You sign off the drawing before we quote final.
Specify & programme
Materials specified to BS EN 1436 against your traffic load. Night, weekend and term-time programming agreed around your operation, not ours.
Prepare & apply
Surface preparation first, always. Then screed, extrusion, spray or preform application by NVQ-qualified, CSCS-carded crews with SSSTS supervision.
Verify & hand over
Retroreflectivity and coverage checked on completion. Photographic records, batch data and maintenance guidance issued with every handover.

What clients say
They re-lined our entire distribution yard across four nights and we never lost a shift. The photographic handover pack alone was worth the fee, our insurers loved it.
The school council designed it, On-Line drew it, and by September the playground had a daily-mile track the children actually use. Three years on it still looks new.
Six hundred bays re-planned, re-lined and reopened before Monday trade, twice. They are the only marking contractor on our term framework for a reason.

Plain-English guidance
How often should road markings be repainted in the UK?
Traffic count, surface type and weather decide the answer, not the calendar. Here is the inspection-led approach we use on term contracts.

Thermoplastic vs paint: which line marking material actually lasts?
Upfront cost per metre is the wrong comparison. Whole-life cost per year of visible service is the right one, and it changes the answer.

Car park marking regulations in the UK: bays, disabled provision and EV charging
There is no single car park marking law, but there is a web of guidance, equality duties and planning conditions that a good layout must satisfy.
