Headlight Restoration
Yellowed, hazy, or oxidised headlights reduce light output by up to 80% and risk MOT failure. Our 4-step restoration — wet sand, compound polish, UV sealant — restores optical clarity and compliance from £45 per headlight.
MOT advisory: Severely degraded headlights can fail an MOT on inadequate light output grounds. Restoration at £45–£75 is significantly cheaper than OEM replacement units (typically £150–£600+ per side).
Why Do Headlights Turn Yellow?
Modern headlights use polycarbonate lenses — lightweight and impact-resistant, but susceptible to UV degradation without proper protection.
UV Oxidation
Polycarbonate lenses absorb UV radiation over time. The outer protective coating degrades, causing the plastic to oxidise and turn yellow or milky.
Reduced Visibility
Yellowed lenses can reduce light output by up to 80%, significantly impairing night driving and increasing accident risk.
MOT Failure Risk
Severely degraded headlights can fail an MOT on the grounds of inadequate light output. Restoration is far cheaper than replacement.
Kerb Appeal
Yellowed headlights age a car's appearance dramatically. Restoration makes a vehicle look years younger and maintains resale value.
What to Expect
Most headlights we restore are returned to near-new optical clarity. The difference is immediately visible — and measurable. Light output typically improves by 60–80% after a full restoration.

Our 4-Step Restoration Process
Every restoration follows the same systematic process to guarantee consistent, professional results.
Lens Assessment
We inspect both headlights for oxidation depth, crazing, and internal condensation to determine whether restoration or replacement is the right call.
Wet Sanding
Progressive wet sanding (400–2000 grit) removes the oxidised outer layer and deep scratches that cause the milky, yellowed appearance.
Machine Polishing
A dual-action polisher with cutting and finishing compound restores optical clarity, eliminating haze and micro-scratches left by sanding.
UV Sealant Application
A professional-grade UV-resistant sealant is applied to protect the restored lens from re-oxidising. Results typically last 2–3 years.

Frequently Asked Questions
How long does headlight restoration take?
Most single-headlight restorations take 45–60 minutes. A pair takes around 90 minutes. We can often fit you in on the same day — call ahead to check availability.
How long will the results last?
With our UV sealant application, results typically last 2–3 years. Parking in shade and applying a UV protectant wax periodically will extend the life of the restoration.
Can all headlights be restored?
Most polycarbonate lenses can be restored. Severely crazed, cracked, or internally fogged lenses may require replacement instead. We assess this during the free initial inspection.
Will restoration fix internal condensation?
No — restoration addresses the external lens surface only. Internal fogging is caused by a failed seal or crack and requires the headlight unit to be resealed or replaced.
Is headlight restoration worth it vs replacement?
For most vehicles, yes. OEM headlight units typically cost £150–£600+ each. Restoration at £45–£75 delivers comparable clarity at a fraction of the cost, provided the lens is not cracked.
Do you offer headlight restoration as part of a service?
Yes — headlight restoration can be added to any vehicle service, vehicle inspection, or bodywork job. Ask our team when booking.
