Ramps and platform lifts at a listed building entrance
Level access at a listed entrance is a balance between two statutory duties. Here is how to rank the options, detail them and present the case for consent.
Level access at a listed entrance needs listed building consent, and the Equality Act duty to make reasonable adjustments does not remove that requirement. What the duty does is change the weight of the argument. An applicant who can show that the proposed ramp or platform lift is the least damaging option capable of delivering access has a much stronger case than one who simply asserts that accessibility trumps conservation.
Most refusals in this area are not refusals of access. They are refusals of a particular detail at a particular position, usually because a less harmful alternative was never tested.
The duty to make reasonable adjustments
Under the Equality Act 2010 a service provider must take reasonable steps to avoid the substantial disadvantage a disabled person faces because of a physical feature. That includes removing the feature, altering it, avoiding it or providing a reasonable alternative means of access. Employers carry a parallel duty towards disabled employees, and public bodies carry the public sector equality duty when they take decisions.
The duty is anticipatory for service providers. It does not wait for a disabled person to arrive and ask. A church, a village hall, a solicitor's office in a Georgian terrace or a museum in a listed mill is expected to have thought about the step at the front door already.
What the Act does not do is tell you which adjustment to make. Reasonableness takes account of cost, practicality, the resources available and the effect of the change, and the Act recognises that an adjustment may require someone else's consent. Schedule 21 deals with that situation, and the upshot is familiar: where a statutory consent is needed, obtaining it is part of taking the reasonable step, and a refusal of consent is relevant to what is reasonable.
Why that duty does not override consent
Section 16 of the Planning (Listed Buildings and Conservation Areas) Act 1990 requires the decision-maker to have special regard to the desirability of preserving the building, its setting and any features of special architectural or historic interest it possesses. Section 66 applies the same special regard where planning permission would affect a listed building or its setting. National policy in the current edition of the NPPF, published on 17 August 2026, requires great weight to be given to the conservation of a designated heritage asset and clear and convincing justification for any harm.
The courts have treated that special regard as a strong presumption rather than one consideration among many. So the accessibility benefit is a public benefit to be weighed, and it can outweigh less than substantial harm, but it enters the balance rather than short-circuiting it.
Practically, that means the heritage case has to be made properly. A heritage statement that identifies what is special about the entrance, says exactly which fabric would be affected and explains why the chosen option harms least is the document that wins these applications.
Options ranked by how much they take away
Work down this list and record why each option above the one you choose was rejected. That record is the argument.
- Change the approach rather than the building. Regrading the path, resurfacing, or moving the level change away from the threshold into the garden or forecourt.
- Use an existing secondary opening that already has level or near-level access, with internal reconfiguration to reach the same spaces.
- A freestanding external ramp that touches the building only where it meets the threshold, demountable in principle, with a handrail detailed as a separate addition.
- A sunken or recessed ramp in the forecourt, which can be visually quieter but involves excavation and often archaeology.
- A platform lift externally, screened or recessed, where a ramp of compliant gradient cannot physically fit.
- A platform lift inside the entrance hall, which removes the external intervention and transfers the harm to internal plan form and often to a floor.
- Alteration of the threshold itself, lowering a step or cutting a stone.
The ordering shifts with the building. In a building whose entrance steps are its principal architectural event, a Palladian portico or a fine stone perron, the external options drop down the list and an internal solution rises. In a plain brick frontage with a single worn step, lowering the threshold may be the quietest answer available.
Gradient is what usually kills ramps on small forecourts. Approved Document M sets maximum gradients tied to the length of each flight, with 1 in 12 acceptable only over a short going and 1 in 20 required over longer runs, a maximum rise per flight, and landings at each end. Do the arithmetic before drawing anything. A 600mm rise at 1 in 20 needs 12m of ramp plus landings, which does not exist in front of most listed terraces.
Secondary entrances and where they stop being acceptable
Taking disabled visitors round the side used to be the standard answer and is now treated with suspicion, for good reason. An entrance that leads through a bin store, that is kept locked, that requires someone to be summoned, or that delivers the visitor into a back corridor rather than the main space is not an equivalent experience.
A secondary entrance can work where it is a real second front door, used by everyone, signposted, open during the same hours and arriving in the same place. The test to apply is whether a wheelchair user and a walking visitor arriving together would separate.
Where a secondary entrance is the only physically possible route, say so plainly and show the comparison you carried out. A conservation officer is far more likely to accept a side entrance that has been justified against the alternatives than one presented as the obvious solution.
Materials, reversibility and the detail that gets approved
Reversibility is the principle that unlocks most of these schemes. An addition that can be removed in fifty years without leaving significant loss is a different proposition from one that cuts historic fabric.
What tends to be accepted:
- A ramp structure that bears on new pads rather than on historic walls, with a tolerance gap and a flashing rather than a chased joint.
- Fixings into mortar joints rather than into stone or brick faces, recorded on the drawings.
- Handrails and balustrades in a plainly modern idiom, slender in section, rather than cast-iron pastiche that competes with the real thing.
- Surfaces that read as a contemporary layer, such as sawn stone, resin-bound gravel or metal grille, chosen for slip resistance and for honesty about their date.
- A platform lift finished in a dark recessive colour with the shaft kept below the cill line where the rise permits.
What tends to be refused: new render over historic brick to tidy the ramp junction, removal of railings to widen the approach, a ramp parapet of the same stone and profile as the original steps, and salvaged material used to fake an older detail. The argument for honest new work over imitation is the same one set out in salvaged materials and the honesty of repair.
Internal level changes behind the front door
Solving the threshold and then arriving at three steps into the main room achieves nothing. Internal level changes in historic buildings are often more constrained than external ones, because floors, staircases and plan form carry much of the significance.
A short internal platform lift in a secondary space, a ramped timber platform over an existing floor that leaves the historic surface intact beneath, or relocating the service being accessed to a ground-floor room are the three moves that most often work. The last is underused. If the first-floor committee room is the problem, moving committee meetings downstairs is a reasonable adjustment that needs no consent at all.
Record the whole route from the pavement to the service in the design and access statement, not just the bit at the door. Officers notice when an access statement stops at the threshold.
Presenting the balance to the conservation officer
The submission that works has five parts. A description of the significance of the entrance and the fabric affected. A statement of the access problem, framed as the substantial disadvantage a disabled visitor faces. The options appraisal with reasons for rejection. The detailed design of the preferred option, drawn at a scale that shows the junctions. And an assessment of harm, stated honestly as no harm, less than substantial harm or substantial harm, with the public benefit of access weighed against it.
Where the applicant is a public body, the public sector equality duty is itself part of the justification and belongs in the file. An equalities impact assessment is the usual vehicle for recording that thinking, and it reads much better alongside the heritage case than bolted on afterwards.
Pre-application discussion is worth more here than almost anywhere else in heritage work, because the conservation officer's view on which option harms least is the view the committee will hear. Go with three options drawn, not one.
This is general guidance, not legal advice. Check the position with your local planning authority and a suitably qualified heritage and access adviser before relying on it, and note that works to a listed building without consent are a criminal offence.

Frequently asked questions
Does the Equality Act override listed building consent?
No. The duty to make reasonable adjustments under the Equality Act 2010 does not remove the need for consent under the Planning (Listed Buildings and Conservation Areas) Act 1990. The Act recognises that an adjustment may require someone else's consent, and whether consent can be obtained is part of deciding what is reasonable in the first place.
Do I need listed building consent for a demountable ramp?
Usually yes, if the ramp is fixed to the building or alters its character, and often for a freestanding one within the curtilage where it affects the building or its setting. A fully temporary, unfixed ramp brought out when needed may fall outside consent, but confirm the position with the conservation officer before relying on it.
What gradient does an access ramp need?
Approved Document M ties the maximum gradient to the length of each flight, with 1 in 12 acceptable only over a short going and 1 in 20 required over longer runs, plus a maximum rise per flight and landings at each end. Calculate the total length before drawing, because many listed forecourts cannot accommodate it.
Is a side entrance an acceptable solution?
Only where it is a real second front door: unlocked during the same hours, signposted, and arriving in the same space as the main entrance. A route through a service yard or one that needs staff to be summoned is unlikely to satisfy the duty, and officers now treat it as a last resort rather than a default.
Which option do conservation officers usually prefer?
The one that touches the least historic fabric and can be reversed. Regrading the approach, using an existing level opening, or a freestanding ramp bearing on new pads tend to be preferred over cutting a threshold stone. Where the steps are the principal architectural feature, an internal platform lift often becomes the quieter answer.
