Length of ramp required to comply with UK Building Regulations

The following table shows the minimum ramp length required to comply with current UK Building Regulations from the Approved Document M: access to and use of buildings, volume 2: buildings other than dwellings

Note: 10m is the maximum length a ramp should be before including a level resting platform of 1.5m minimum length.

Also note: The inclusion of level resting platforms sometimes take up less room than a single ramp

For example a single ramp rising 500cm would be a maximum gradient of 1:20 and 10m long

By including a 1.5m level platform at the mid point 25cm high the 2 sections of ramp can have a 1:13.5 gradient which means a length of 3.5m

The total space required would be

3.5m ramp – 1.5m platform – 3.5m ramp = total 8.5m a saving of 1.5m

The below diagram demonstrates that including level platforms actually reduces the total length of ramping required.

By reducing the height the gradient (steepness) can be increased resulting in a reduced total length
