A scaffold gang can be ready to erect, the lorry can be loaded and the programme can be tight, but none of that helps if the site manager will not let you through the gate. Insurance evidence for site access is often a non-negotiable part of pre-start checks, particularly on commercial, public-sector and main-contractor sites.
Getting the right paperwork over early is not just an admin job. It protects your start date, your relationship with the contractor and your cash flow. A missing certificate can leave a crew standing down while another contractor gets the work.
What is insurance evidence for site access?
Insurance evidence is the documentation a client, principal contractor, site manager or local authority asks for to show that your scaffolding business holds the cover required for the work. Usually, they want a current certificate of insurance. Depending on the contract, they may also ask for a policy schedule, a broker confirmation letter or evidence of a specific indemnity limit.
The request is not simply a box-ticking exercise. Scaffolding affects people working above and below the structure, nearby properties, passing vehicles and members of the public. Where a scaffold sits on a pavement or highway, the exposure extends beyond the site boundary too.
A certificate proves cover was in force when it was issued. It does not always set out every policy term, exclusion or condition. That is why larger projects sometimes ask for more detail. If they do, do not assume a generic certificate will settle it. Check exactly what they need and when they need it.
The documents sites commonly request
For most scaffolding contractors, public liability evidence is the first document a site will ask for. It confirms the insurer, policyholder name, policy dates and indemnity limit. Many construction sites set a minimum limit of £5 million, while higher-value, city-centre or infrastructure work may require £10 million or more.
If you employ staff, including labourers or apprentices, you will normally also need employers’ liability insurance. The certificate should be available for inspection, and site teams commonly request a copy during onboarding. Employers’ liability is a legal requirement for most businesses with employees, although limited exceptions can apply.
You may also be asked for evidence of the following where the job calls for it:
- motor fleet or commercial vehicle cover for vehicles entering or operating around the site;
- hired-in plant cover if you are using hired equipment and your hire agreement makes you responsible for it;
- contract works cover where your contract requires protection for work in progress or materials on site;
- professional indemnity cover where you have design responsibility or provide drawings and specifications; and
- personal accident cover, which is not usually a site-access requirement but can help protect income following a serious injury.
Not every policy is relevant to every job. Sending a full bundle of unrelated documents can create more questions, not fewer. Start with the contractor’s insurance schedule or pre-qualification request, then provide the evidence that matches it.
Public liability: the document that usually opens the gate
Public liability cover is central for scaffolders because it responds to claims alleging injury to a third party or damage to their property arising from your work, subject to the policy terms. A falling fitting, damaged window, blocked access route or a pedestrian injury near a pavement scaffold can all lead to expensive allegations.
The key point is the limit. A £2 million public liability policy may be suitable for some smaller private jobs, but it will not meet a contract that demands £5 million or £10 million. You cannot talk a site manager into accepting a lower limit just because the scaffold is only up for a week. Their requirement will usually be tied to the principal contractor’s own risk rules.
Check whether the limit is required per claim, in the aggregate, or subject to any specific wording. It is also sensible to confirm that the nature of your work is accurately declared. If you undertake high-rise, complex or unrestricted-height scaffolding, your cover needs to reflect that reality.
Why a certificate is not always enough
A site may ask for an “insurance certificate” but reject what you send because the company name is wrong, the policy has expired or the indemnity limit is not visible. These are common, avoidable hold-ups.
Your trading name, legal entity and address should match the contract or onboarding form. This matters for sole traders who have changed trading names, limited companies with several brands, and groups where vehicles or employees sit under a different entity. If the insured name does not match, ask your broker whether a confirmation letter is appropriate rather than altering paperwork yourself.
Some contractors also request confirmation of specific extensions, such as work at height, work away from your premises, use of heat, highway work or the height limit applicable to your scaffold operations. Do not promise that a policy includes these features until they have been checked against your actual arrangement.
A practical way to avoid site delays
Treat insurance evidence like an essential part of the job pack, alongside RAMS, training records, inspection arrangements and permits. As soon as a job is awarded, ask for the client’s insurance requirements in writing. Do not wait until the crew is due on site.
First, compare the requested limits and policy types against your current cover. Second, make sure the policy dates cover the whole working period, including any likely extension. Finally, send clean, current PDFs with a clear file name, such as “ABC Scaffolding Public Liability Certificate 2026”. A site administrator should be able to identify the document in seconds.
Keep a controlled folder for certificates and schedules, with old versions archived separately. This avoids the classic mistake of forwarding last year’s certificate from a phone while standing at the gate. If your policy renews mid-project, send the replacement evidence before the old policy ends.
For regular work with principal contractors, it can help to maintain a one-page insurance summary. This should state your legal business name, the policy classes held, indemnity limits, renewal dates and broker contact details. It is a useful sign that you are organised, but it should support rather than replace the formal certificate where one is requested.
Pavement licences, highway permits and local authority requests
Scaffolds on public pavements and highways bring another layer of checks. The council or highways authority may require proof of public liability cover before issuing a licence, often at a stated minimum limit. Your client may also ask for evidence before allowing a pavement application to proceed.
Requirements vary by authority. One council may accept a certificate showing the required limit, while another may ask for wording linked to the licence application. Allow time for this. A licence cannot usually be treated as an afterthought once materials have arrived.
Remember that insurance evidence is only one part of the process. You may still need a scaffold licence, traffic management arrangements, lighting, pedestrian protection and compliance with the conditions imposed by the authority. The certificate does not replace safe planning on a busy street.
When the contract asks for more than your policy provides
Do not ignore a higher limit or unusual wording in the hope it will not be checked. If a contract requires £10 million public liability and you hold £5 million, raise it with your broker before signing or starting the work. In some cases, an increased limit or project-specific arrangement may be available. In others, the risk, insurer appetite or contract wording may mean it is not suitable.
The same applies to requests to name a principal contractor, waive rights of recovery or accept contractual liabilities beyond normal trading terms. These are technical points with real consequences. A quick conversation early is far easier than discovering a gap after an incident.
Scaff Cover can help scaffolding businesses check whether their insurance evidence matches a contractor’s request and arrange practical documents where appropriate. The aim is straightforward: less time chasing paperwork, more time focusing on the job.
Before the next mobilisation, take five minutes to check your certificates, renewal dates and indemnity limits. A tidy insurance pack will not erect the scaffold for you, but it can make sure your team is allowed on site to do exactly that.
