Westmark Protected Premises Mark

Find out where you stand before the duty bites

An independent, on-site assessment for responsible persons under the Terrorism (Protection of Premises) Act 2025. It records what was in place, scores it against a published standard built on the Home Office statutory guidance, and puts the outcome on a public register.

Assessments open October 2026. Enquiries and scoping are open now.

Protective bollards, Horse Guards Road, London.

Is this for you

The Act received Royal Assent on 3 April 2025 and commencement is expected in spring 2027. The Home Office statutory guidance tells you what the duty requires, and the Security Industry Authority will regulate compliance. The Act leaves it to you to show that your arrangements were in place. Section 27(5) says that proof of having acted in accordance with the guidance may be relied on as tending to establish that no contravention occurred, and a dated, independent record of what was in place is how you show it.

The mark is for you if

  • You are the responsible person for premises or an event that the Act will reach, and you want to know where you stand before the duty commences
  • You want a dated, independent record that the procedures work
  • You want front-line staff, the lockdown and the communications tested by somebody outside the organisation
  • You hold several premises. Councils and multi-site operators can licence the assessment tool for the whole portfolio. Licence the assessment tool

Which tier you fall in

  • Standard200 to 799 people expected. Public protection procedures: evacuation, invacuation, lockdown and communication
  • Enhanced800 or more. The procedures above, plus public protection measures, a designated senior individual and a documented statement
  • EventsA qualifying event is assessed across the document stage, build, show and close-out

Westmark claims no special standing under the Act. An outcome is a dated, independent record and Westmark's own judgement.

Three products

One for each tier and one for events. The product is fixed at scoping from the tier the premises falls in, and every product scores the same twenty controls.

  • Enhanced premises assessment

    For enhanced duty premises. A site visit set by the assessor, with direct verification: the lockdown timed with the staff actually on duty, the public address and radio channels tested live, and front-line workers asked to describe their own part in their own words.

    Reaches the Mark, Conditional or Not Confirmed, with a confidence level.

  • Qualifying event assessment

    For a qualifying event. Assessed across the document stage, the build, the show and the close-out, so the record reflects the event as it actually ran.

    Reaches the Mark, Conditional or Not Confirmed, with a confidence level.

  • Standard premises declaration

    For standard duty premises. A desk review with a remote interview. It confirms the four procedures exist and that workers have been briefed on them, and it is carried out entirely at the desk, so it reaches an outcome without a score or a confidence level.

    Reaches Declared or Not Declared. Wherever Declared is claimed, the holder must state that no site visit was made.

What is examined

Twenty controls in five sections, published in advance in the Control Set. Sections P1 to P3 apply to every assessment. P4 and P5 apply to enhanced duty premises and qualifying events only.

  1. P1Scope and registration4 controls. What the premises are, which tier, who is responsible, what the SIA needs to be told
  2. P2Public protection procedures6 controls. The four procedures, whether the set is appropriate, and workforce readiness
  3. P3Governance2 controls. The designated senior individual and, where they arise, structural conditions
  4. P4Public protection measures5 controls. Four measure categories and the vulnerability assessment they derive from. Enhanced and events
  5. P5Documentation and records3 controls. The statement, the machinery that keeps it current, and the record set. Enhanced and events

How the evidence is judged

  • Every control cites the section of the Act or the paragraph of the section 27 guidance it rests on, so the record is useful under section 27(5)
  • At the enhanced tier the lockdown is timed and the communications are tested live, on the day, with the people on duty
  • Front-line workers are interviewed on their own, unless the worker asks otherwise
  • Full marks on any control need evidence from more than one independent source
  • Nine disqualifying conditions apply. Any one of them stops a positive outcome regardless of the score

Read the criteria before you commit

The standard is issued for use at version 0.9. Four items are held open until the Security Industry Authority publishes its guidance under section 12, expected in autumn 2026. Version 1.0 follows when it does, and every assessment states the version it was carried out against.

How it runs

The same seven steps under both schemes. Every one happens in the Westmark hub, and every screen says whose turn it is and what is waiting. From agreement to outcome we plan on four to eight weeks, set with you at scoping.

  1. Westmark and you

    Scope

    What premises you hold, the expected attendance, and which tier and product fit.

  2. Westmark, then you

    Quotation and agreement

    Issued in the hub and accepted on screen. Nothing is signed until both are in writing.

  3. Westmark

    Assessor assigned

    Authorised for the scheme and the tier, and independent of any advice you have had.

  4. You

    Self-assessment

    Plain questions in the hub, one for each control. It tells the assessor where to spend the time.

  5. Your assessor

    The assessment

    On site for enhanced premises and events, remote for a standard declaration. Anything adverse is put to you before it settles.

  6. A second assessor

    Technical review

    Somebody independent of the assessment confirms the record or returns it with reasons.

  7. Westmark

    Outcome and register

    Documents issued in the hub, the entry published, and the claim wording sent to you.

How assessment works, in full

The outcomes

Enhanced premises and qualifying events reach one of three scored outcomes, each with a confidence level. A standard premises declaration reaches one of two.

  • Protected Premises Mark

    Overall 80 per cent or above, no section below 50, no disqualifying condition, procedures consistent across the operating pattern.

    On the register for twenty-four months, with an annual declaration at twelve.

  • Protected Premises Conditional

    Overall 60 to 79 per cent, or the Mark thresholds met but for a section floor or an inconsistency. Improvement actions attached, completable within three to six months.

    A positive outcome, published on the register with the actions shown.

  • Not Confirmed

    Below 60 per cent, or a disqualifying condition met.

    Nothing appears on the register.

  • Declared

    Standard premises declaration only. Every assessed control scores 1 or above and no disqualifying condition is met.

    Rests on a desk review and a remote interview, with no score or confidence level, and the claim must say that no site visit was made.

  • Not Declared

    Any assessed control scores 0, or a disqualifying condition is met.

    Not published. You may submit again after three months.

What it costs

Fees follow the product and the expected attendance recorded at scoping. The full fee is quoted in writing before the Assessment Agreement is accepted, and it is the same whatever the outcome.

Standard premises declaration
Half an assessor day, carried out remotely
Enhanced premises, under 5,000 expected
One day on site, half a day at the desk
Enhanced premises, larger or several buildings
Two to three days on site, with desk time to match
Qualifying event
Two days across document stage, build, show and close-out
A portfolio
Charged per premises. Councils and multi-site operators can licence the tool for the whole portfolio

Getting ready

Most responsible persons find gaps on a first read of the Control Set, and scoping, which is where they surface, costs nothing. Where you want help, Westmark introduces you to a Licensed Partner: a consultancy Westmark has approved, whose consultants work with your people so the procedures, training and briefing records are written around this premises and belong to you.

What a partner does

  • Goes through the published Control Set with you and says plainly what is missing, before anything is booked
  • Advises on what each control is really asking, then works with your people so the procedures, training and briefing records are yours
  • Stays with you between assessments, so the arrangements move when the premises, the operating pattern or the people change

Kept apart from the judgement

  • During the assessment you speak for yourself, and the partner stands aside
  • Your assessor is always independent of your partner. The hub enforces that automatically at assignment
