Expert Care
For Every
Journey

Regular professional servicing is vital to maintaining your vehicle’s resale value, reliability, and performance while preventing costly mechanical issues. Our thorough service includes changing the engine oil and filters with the correct grade, cleaning and greasing brakes, and checking fluids, lights, tyres, pressures, and suspension.

We use only high-quality parts equivalent to original equipment. Modern engines require manufacturer-specific oils due to advanced systems and emissions regulations, so we ensure the correct oil is always used. Plus, servicing with us won’t affect your manufacturer’s warranty, you’re free to choose trusted professionals for your vehicle’s care.

Ensure your vehicle is safe, legal, and roadworthy with a professional MOT at G & L Marshall. Our licensed engineers carry out MOT tests for vehicles in Classes 4, 5, and 7, including cars, motorhomes, ambulances, taxis, and goods vehicles.

MOTs check that your vehicle meets road safety and environmental standards, helping you avoid costly issues and stay compliant with UK law. Our team inspects everything thoroughly, giving you confidence that your vehicle performs safely on the road.

With clear pricing and expert service, we make MOT testing simple, reliable, and convenient for every vehicle type.

Correct wheel alignment ensures your vehicle handles safely and stops typos wearing unevenly. Using advanced 3D wheel alignment technology, we measure your vehicle’s wheel angles with precision, adjusting them to manufacturer specifications improving fuel efficiency, handling, and tyre life.

Misaligned wheels can be caused by potting holes, kerbing, or worn suspension components. If your car pulls to one side or the steering wheel isn’t straight, our expert alignment service will get you back on track.

Keep your tyres safe and legal with expert checks from G&L Marshall. We ensure your vehicle has the correct size and type of tyre and advise on the best course of action. Our workshop stocks a wide range of regular and winter tyres and can source others on request.

UK law requires tyres to have a minimum tread depth of 1.6mm, though many manufacturers recommend replacement at 3mm for safety.

Winter tyres provide superior grip in cold or damp conditions, enhancing safety beyond snow and ice.

Stay cool in summer and demisted in winter with our air conditioning services. Over time, AC systems lose refrigerant gas, reducing efficiency. We offer regassing and leak testing for both R134a and R1234yf systems.

We also clean and sanitize your system to remove bacteria and bad odours.
