Follow Approved Document M and BS 8300-2:2018 for every non-domestic building, and treat the Equality Act 2010 as the legal backbone that makes tactile signage a duty, not an option. Mount tactile and Braille signs at a centreline of 1500mm (±100mm), and specify Braille dimensions to BS EN ISO 17049. Get that one measurement right and prioritise the accessible toilet, the lift, and the refuge point first.
TL;DR:
- Signage must be mounted at a centreline height of 1500mm ±100mm, with relief and Braille dimensions specified precisely according to BS EN ISO 17049.
- Braille is only required at high-priority points like accessible toilets, lift controls, and refuge points, not on every sign throughout the building.
- Specifications should include numeric tolerances, physical sample approval, and measurements taken on site to prevent compliance disputes.
- Responsibility for non-compliance rests with the organization, which must conduct audits, train staff, and embed QA checks in contracts to ensure proper signage standards.
- Using in-house manufacturing and detailed procurement clauses reduces errors caused by vague specifications and third-party misinterpretations.

What are the braille signage requirements UK law actually sets out?
There isn’t a single “braille law” in the UK. Compliance rests on three documents working together, and facilities teams who only check one of them usually get caught out.
Approved Document M is the building-regulations baseline for access to and use of buildings other than dwellings, and it has applied to non-domestic buildings since 1 October 2015. It sets the principle that people with sensory impairments need tactile and visual information, then points designers straight to BS 8300-2 for the technical detail. It won’t tell you the exact height or dot spacing. It tells you where to look.
That’s where BS 8300-2:2018 comes in. This is the working document for anyone specifying, ordering, or accepting signage. It gives the mounting heights, tactile relief tolerances, and contrast benchmarks that turn a vague duty into a measurable spec.
Underpinning both is the Equality Act 2010. Service providers must make reasonable adjustments for disabled people, and the Act’s accompanying code of practice names signage replacement or provision as an auxiliary aid. That’s the legal teeth behind the technical standard.
- Approved Document M: statutory baseline, points to BS 8300-2 for detail
- BS 8300-2:2018: the practical specification document for tactile and Braille signs
- Equality Act 2010: creates the duty to act, with signage as a named remedy
Where does tactile and braille signage actually need to go?
Not every door needs a Braille plate. Raised tactile lettering has the wider requirement across a building; Braille is expected at a smaller set of high-priority points where someone with sight loss needs to identify a space independently.
- Accessible toilets — door signs identifying the facility and any specific features
- Lift landings and controls — floor identification and control panel labelling
- Refuge points — clear identification for fire evacuation strategy
- Stair identification — floor level signs at half-landings and stair cores
- Main wayfinding junctions — key decision points in a building’s circulation route
Listed buildings and temporary structures need judgement rather than a blanket rule. A Grade II listed hotel may need alternative fixing methods that avoid damaging historic fabric, while an exhibition stand or pop-up unit still needs to meet the same tactile principles wherever it functions as permanent wayfinding for the duration of the event. Guidance on integrating this into a wider wayfinding signage design strategy is worth reading before you commission anything.
Braille sign standards UK teams should specify to the millimetre
This is where most disputes start, because “compliant” and “close enough” are not the same thing. Get these numbers into the tender document and there’s very little room for a supplier to argue later.
Pro Tip: Write the tolerance into the purchase order, not just the drawing. “1500mm ±100mm centreline” on an invoice gives you grounds to reject a delivery that a verbal brief never would.
- Mounting height: centreline at 1500mm ±100mm for tactile and Braille signage, sitting within the broader 1400 to 1700mm range used for general signage
- Braille dimensions: dot spacing, cell spacing and dot height set by BS EN ISO 17049
- Braille grade: use Grade 2 (contracted) Braille as standard, reserving uncontracted Grade 1 for very short single-word messages, per RNIB guidance
- Contrast: aim for a Light Reflectance Value difference of roughly 70/30 between text and background, checked under real site lighting rather than a lightbox
- Exclusion zone: keep a 6mm clear margin around Braille cells so fingers can locate the dots without interference from surrounding text or borders
The relief figure matters more than most specifiers realise. Anything under 0.8mm and the tactile lettering becomes nearly impossible to distinguish by touch, which is one of the most common reasons a sign gets rejected at handover.
Getting installation and testing right first time
A perfectly specified sign fixed in the wrong place is still a non-compliant sign. Installation and acceptance testing catch the errors a drawing can’t.
- Mount on the latch or handle side of the door, roughly 100mm from the frame, so a visitor’s hand naturally lands on the sign while reaching for the handle
- Avoid mounting on the moving leaf of a door, since an open door hides the sign exactly when someone needs it
- Test tactile legibility by touch, not just by eye, ideally with a colleague or access consultant who can confirm the relief is readable
- Check contrast under actual site lighting, since LED colour temperature and daylight glare both shift how a sign reads compared with how it looked on a lightbox in the workshop
- Record acceptance measurements at handover: centreline height, tactile relief depth, Braille cell dimensions, and a contrast reading taken on site
Pro Tip: Keep a small tactile relief gauge and a tape measure in the facilities toolkit. A five-minute spot check on delivery catches a batch error before it’s fixed to fifty doors.
Testing contrast on site rather than in a factory lightbox is a small step that avoids one of the more expensive mistakes in signage procurement: a full reprint after a batch fails on-site inspection.
A procurement checklist for tenders and handover
Building the right clauses into a tender document does more to prevent disputes than any amount of chasing after installation. A3M’s own Braille signage procurement checklist sets out the fuller version of this, but the essentials are:
- Reference BS 8300-2:2018 and BS EN ISO 17049 by name in the specification, not just “compliant Braille”
- State tolerances explicitly (centreline, relief depth, dot dimensions) and name the test method for each
- Require a signed-off physical sample before bulk production begins
- Photograph the approved sample and keep it on file against the delivered batch
- Require documented acceptance checks and measurements at handover, not a verbal sign-off
| Checklist stage | What to require |
|---|---|
| Specification | Named standards, numeric tolerances, test methods |
| Sample approval | Physical sample signed off before production |
| Handover | Measured centreline, relief depth, cell dimensions, contrast reading |
Skipping the sample-approval step is the single biggest cause of reprints on multi-site rollouts, where one factory error can end up on forty doors before anyone spots it.
Who’s responsible when signage falls short?
Responsibility sits with the service provider, not the sign manufacturer, though a poor supplier can certainly cause the failure. Under the Equality Act, it’s the organisation running the building or service that carries the duty to make reasonable adjustments, and that duty doesn’t disappear because a contractor delivered the wrong spec.
- Commission a documented access audit rather than relying on informal judgement
- Train front-of-house and facilities staff to recognise when a sign is missing, damaged, or wrongly positioned
- Keep a written accessibility policy that references the standards you work to
- Build QA obligations into supplier contracts so acceptance testing is contractual, not optional
Regulatory guidance around Approved Document M and BS 8300 explicitly recommends audits and records as evidence of reasonable adjustments, which matters if a complaint ever reaches a tribunal. It’s also worth reviewing wider accessibility practices across an organisation’s communications, since a joined-up policy on physical and digital access tends to hold up better under scrutiny than signage treated in isolation.
Where procurement usually goes wrong
Most non-compliant signage doesn’t come from ignorance of the standards. It comes from vague specification and no sample sign-off. A brief that says “Braille signage to BS 8300” without numbers gives a supplier room to interpret tolerances however suits their production line, and flattened or uneven Braille dots are consistently the most common quality failure reported once signs reach site.
The fix is almost boringly simple: write the numbers down, ask for a physical sample, and check it against the standard before a single door gets fitted. In-house manufacturing helps here too, because there’s no third-party production run to chase when a tolerance is wrong. Fewer handoffs mean fewer places for a spec to get lost between drawing and delivery.

Specifying and installing compliant signage without the guesswork
A supplier offering tactile and Braille signage services can streamline the process for facilities teams who prefer not to coordinate separate designers, manufacturers, and installers across different contracts. In-house manufacturing allows sample approval, production, and quality checks to occur in one place, with a consistent team managing the process from specification to handover.
The engagement path is straightforward: a site survey to confirm mounting locations and existing conditions, a signed-off physical sample against your BS 8300-2 and BS EN ISO 17049 specification, then production and installation with documented acceptance checks at handover. That structure removes the two biggest risks in signage procurement: vague specifications and unapproved samples reaching site.
If you’re planning a refresh across accessible toilets, lifts, refuge points, or main wayfinding junctions, get in touch through the signage services page to scope a survey and request a sample for your next project.

FAQ
What are the requirements for Braille signage in the UK?
Braille signage requirements UK-wide combine Approved Document M’s statutory baseline with the detailed technical specification in BS 8300-2:2018, covering mounting height, tactile relief, and Braille dimensions under BS EN ISO 17049. The Equality Act 2010 makes providing these signs part of a service provider’s duty to make reasonable adjustments.
Is Braille required on every sign?
No. Raised tactile lettering is the wider requirement across a building, while Braille is expected specifically at high-priority points such as accessible toilets, lift controls, and refuge points. Specifying Braille only where BS 8300-2 recommends it keeps costs proportionate without breaching the standard.
What height does a Braille sign need to be at?
The centreline for tactile and Braille signage should sit at 1500mm ±100mm, per BS 8300-2:2018. This tolerance allows for practical variation across a building while keeping signs within reach and eye level for most users.
How much do Braille signs cost?
Cost depends on quantity, material, and finish, so there’s no single figure that applies across every project. A3M provides signage pricing on request once a survey and specification are confirmed, which you can arrange through the signage services page.
