About Steering Developments
Over 40 years fitting driving adaptations that give people their independence back.
We're the team Motability, occupational therapists and drivers across the UK turn to for the simplest to the most complex driving control installations — based in Hemel Hempstead, working nationwide.

Who we are
Steering Developments Ltd (SDL) started in 1981, when seven engineers pooled their knowledge to set up the company now known across the industry for solving driving adaptation problems other installers can't.
Over four decades, that's grown into a specialist team fitting driving controls and adaptations — from a simple left-foot accelerator to a full Paravan SpaceDrive and Joysteer electronic driving systems — to vehicles that have already been converted for wheelchair access.
We don't convert vehicles or sell WAVs ourselves. We're the Stage 2 specialist that Motability, OTs and WAV converters trust and bring in once the vehicle is ready, to fit and calibrate the controls that let someone actually drive it.
The team behind SDL

Grant Harbour & Stuart Parker
SDL is run day-to-day by Grant and Stuart, who between them have decades of experience in vehicle adaptation and have shaped the company's approach to customer service and quality control. The team has grown to keep pace with demand, and continues to take on installations other specialists turn away.

Three things customers tell us matter most when they're trusting someone to adapt the vehicle they depend on.
Bespoke, not off-the-shelf
Every installation is built around the individual — how they move, what they can do unaided, and what they need help with. We won't rush a decision, and if something isn't right for you, we'll say so rather than sell it anyway.
Constant innovation
We take on adaptation challenges other installers won't, for private customers and through Motability. Our technicians keep testing new approaches — from lightweight power steering conversions to new control configurations — to widen what's possible.
A standard others measure against
We invest in ongoing training and stay current with industry best practice. It's why WAV converters and dealers across the country refer their customers to us for the driving control installations they can't do themselves.

The story behind Steering Developments
Four decades of experience
Steering Developments Ltd was established in 1981, when seven engineers grouped their resources and knowledge to start the company now known as SDL. That founding team's approach — solve the problem properly, or say you can't — is still how we operate today.
