Compatibility, fitting & aftercare
Why prices are quoted for your vehicle
Modern cars differ a lot — steering systems, electronics, airbags, dashboards and mounting points. What fits one model may need different parts, programming or labour on another. The figures on this page are a starting point for supplied & fitted work; we confirm a firm price once we know your make, model and year, and have checked compatibility.
Workshop fitting vs mobile
Most adaptations are fitted at our Heathrow or Ferndown workshops, where we have the tools, lifts and diagnostic equipment to do the job properly. Some simpler fittings can still be done at your home or a dealership when the product and vehicle allow — we'll say so when we quote. We never force a mobile fit where workshop conditions are safer or required by the manufacturer.
Area we cover
We focus on local service from our two workshops — roughly within about 30 miles of Heathrow (West Drayton) and about 60 miles of Ferndown (Wimborne). Collection and return of your vehicle, home visits and mobile work (where suitable) sit inside those bands. Outside the area you can usually still bring the vehicle to us, or ask about options when you request a quote.
