How steep can ramps be?

We advise that a ramp gradient should not be steeper than the maximum gradient and meet the minimum set by Part M of the Building Regulations. Preferably a shallow and practicable incline should be achieved.

A steep ramp slope produces difficulties for wheelchair users, especially those with a lack of upper body strength to propel themselves up. Similarly, a steep gradient will make it difficult for a caregiver to push a hospital bed or wheelchair user safely.

The Part M regulations state that a ramp must meet a minimum gradient.

The maximum gradient that your ramp can reach is determined by the change in rise (aka the height) to overcome.

If the maximum gradient has been reached, a resting platform must be provided to allow the user to pause, as they may become tired and out of breath.

?A dwelling ramp often can often accomplish a gradient of 1:12.

Public access ramps often can accomplish a minimum ramp gradient of 1:15 and 1:20 gradient is frequently specified.

Widths of ramps

A ramp’s width is just as crucial as the gradient. Buildings and spaces for public use must have a minimum ramp width of 1500mm, while this is 900mm for dwellings.

Other widths are available with our modular ramp system. A wider platform can accommodate footfall travelling in two directions and provide turning space for transportation beds and electrically operated wheelchairs/scooters.

Complete list of widths available:

900mm – the recommended width for dwellings under Document M, Section 6 of the Building Regulations.
1000mm – our standard modular wheelchair ramp for dwellings.
1200mm – our slightly wider modular ramp.
1500mm – the recommended width for modular ramps for public buildings.

Any of the above can be secured together to create almost any width.
