Common questions
What is a Major Service?
A Major Service is the most comprehensive annual service, following your car's manufacturer schedule. It includes everything in a Full Service plus spark plugs, brake fluid flush, coolant change, and a full road test — typically due every 2 years or 24,000 miles.
How is it different from a Full Service?
A Full Service covers the standard 12-month checks. A Major Service adds component replacements that are due on a longer cycle — spark plugs, fluids that degrade over time, and a manufacturer-schedule compliance check.
Does this protect my manufacturer warranty?
Yes. UK Block Exemption Regulation law means using a qualified independent garage with correct spec parts and oils keeps your warranty fully valid.
How long does a Major Service take?
Typically 3–4 hours depending on the vehicle. We will always confirm timing when you book and text you when the car is ready.
Can I combine it with an MOT?
Absolutely — many customers book both together. It saves a separate trip and we can usually fit both in one visit.
