How to Track Accreditation Renewal Deadlines Without Losing a Contract

Most subcontractors treat accreditation renewal deadlines as one date a year: the day the invoice lands. That is the single most expensive assumption in construction pre-qualification admin, because every major scheme actually runs two or three separate clocks — a payment clock, an assessment clock, and a set of document-level expiry dates buried inside your profile. Miss the wrong one and your status flips on a client portal on a Tuesday morning, which is usually the same morning a main contractor's supply chain team runs its monthly compliance report.

TL;DR

Almost every UK construction accreditation runs on a 12-month cycle, but the 12 months does not start on the same day for each of them. CHAS states plainly that membership expiry is your annual payment date while compliance expiry is your annual assessment renewal — two different dates on the same account (CHAS FAQ). SSIP mutual recognition does not reset the clock: a Deem to Satisfy certificate expires when the original full assessment behind it expires, not 12 months after you took it out (Smas Worksafe, SafeContractor). And a certificate that is technically "valid for a year" can still be undermined mid-year — Build UK's Common Assessment Standard certificate runs for one year provided time-critical documents are kept updated when they expire. The fix is a single dated list of five things: your parent assessment date, each scheme's payment date, every child DTS certificate, your insurance renewals, and your training certificates.

Why do accreditation renewal deadlines catch subcontractors out?

Because the schemes are selling you two different things at once, and the two things expire independently. The subscription is a commercial contract with a payment date. The certificate is an assessment outcome with an assessment date. CHAS spells this out for contractors: membership expiry is the annual payment date, compliance expiry is the annual assessment renewal (CHAS FAQ). Alcumus SafeContractor's contractor terms make the same distinction from the other direction, noting that the annual review date of the accreditation may not coincide with the membership renewal date (SafeContractor contractor terms, January 2022 version — re-check the current version before relying on the detail).

The practical consequence is that you can be fully paid up and still non-compliant, or fully assessed and still suspended for non-payment. Neither state is any use to you when a client's portal is checking whether you're green.

The second trap is document-level expiry. Constructionline's own membership guides explain that once your requirements are verified they each carry individual expiry dates, visible per requirement in the Requirements app, with an email reminder and an 'Action Required' flag 30 days before expiry (Constructionline Gold & Platinum membership guide, February 2026). Your employers' liability policy renewing in November has nothing to do with your membership renewing in September — but it can knock a hole in your verified status all the same.

What actually expires, and when?

The two notice periods are worth pinning to the wall. SafeContractor states that all memberships auto-renew and that you need to tell them at least 14 days before the renewal date if you don't want to continue (SafeContractor certification FAQs). The CHAS contractor/supplier terms published in 2023 refer to 14 working days' written notice prior to the start of the next renewal (CHAS contractor/supplier terms v3.0). If you're planning to switch schemes to save money, those two windows decide whether you pay for a year you didn't want.

Does SSIP mutual recognition reset your renewal date?

No — and this is the single most useful thing on this page. Deem to Satisfy lets you passport an existing, valid SSIP certificate across to another member scheme cheaply, but the passported certificate inherits the original expiry date. Smas Worksafe states it directly: DTS lasts only as long as your current SSIP certificate, so six months left on your SSIP means six months on your DTS (Smas Worksafe SSIP certification). SafeContractor describes the same mechanism from its side — a certification obtained this way is issued for a year but is suspended when the original SSIP member certification expires (SafeContractor SSIP).

So your accreditation estate has a parent and one or more children. The parent is the full assessment you actually sat. The children are the DTS certificates hanging off it. Renew the parent late and every child goes down with it — including ones you took out months later and mentally filed under a different date. That is precisely the residual admin pain that mutual recognition does not remove, and it's covered in more depth in what SSIP mutual recognition does not cover.

What is the Common Assessment Standard renewal cycle?

Build UK, which owns the Common Assessment Standard question set, states that companies holding the standard are certified once a year by a Recognised Assessment Body (Build UK, Common Assessment Standard). The question set itself adds an important condition: the certificate is valid for one year from the date of issue provided that any 'time-critical' documents are updated when they expire (Common Assessment Standard question set, version 5, 1 July 2025).

Read that clause properly, because it changes how you should think about the whole year. A CAS certificate is not a twelve-month holiday from paperwork. It's a twelve-month permission that is conditional on your insurance certificates, licences and time-limited evidence staying in date underneath it. If your public liability policy lapses in month seven, the underlying condition of the certificate has gone even if the PDF on your wall still says next March. More on the standard itself in the Common Assessment Standard explained guide.

A worked example: five dates for a 12-engineer M&E firm

Say a 12-engineer electrical and mechanical firm holds a full Smas Worksafe SSIP assessment, took a DTS across to SafeContractor in June because a facilities management client insisted on it, and holds Constructionline Gold for public-sector framework work. Here is what the year actually looks like.

The firm's owner is carrying "March" and "September" in his head. What he isn't carrying is that the June DTS certificate dies in March, and that the November insurance renewal needs re-uploading to the Constructionline profile within days, not whenever he next logs in. Two invisible dates out of five — and both of them are the type that turn a green tick amber right before a tender submission.

Note also the shape of the money. The parent assessment is the expensive one; the DTS is the cheap one. If the parent lapses, you don't just re-buy the cheap certificate — you're back to a full assessment. The cheapest SSIP scheme comparison is only cheap if you keep the parent alive.

How do you build a renewal tracker that actually works?

1. 1
   Log into every portal once and write down both dates. Not the date you think it is — the date the portal says. For CHAS that means recording membership expiry and compliance expiry separately. For Constructionline it means the membership expiry plus each requirement's individual expiry date.
2. 2
   Mark the parent and the children. Identify the one full assessment that other certificates were deemed to satisfy against, and note next to each DTS certificate: "expires with parent, DD/MM/YYYY".
3. 3
   Add the time-critical documents. Employers' liability, public liability, professional indemnity, any trade licences, and the training certificates that carry an expiry (site supervisor and manager cards being the usual culprits). These are what the Common Assessment Standard means by documents that must be updated when they expire.
4. 4
   Work backwards, don't wait to be told. Set your own reminders at 90, 60 and 30 days before each date. Scheme reminders exist — SafeContractor emails 60 days before expiry, Constructionline flags 30 days before — but they land in the same inbox as everything else, and 30 days is not much runway if an assessor comes back asking for a reworded policy.
5. 5
   Book the work, not just the date. A reminder that says "CHAS due" is a nag. A reminder that says "CHAS due 14/03 — pull H&S policy, last 12 months of accident records, updated training matrix" is a job you can actually do at 5am with a brew.

If you'd rather not maintain this by hand, TradeComply is building a renewal and evidence tracker for exactly this problem: one place for the parent assessment date, the child DTS certificates, the payment dates and the document expiries, with the re-upload reminders attached. It isn't live yet — the waitlist is open.

What happens if you miss a renewal date?

In commercial terms, the damage is rarely the fee — it's the gap. Your entry on a client portal changes state, and a main contractor running a monthly supply chain report sees the change before you've noticed the email. For recurring commercial maintenance work, that's how a modest annual contract quietly goes to whoever was green that week.

On the scheme side, the consequences differ and are worth checking in your own terms rather than assumed. The CHAS FAQ notes, for example, that an application closed for less than 14 days can be reopened for a fee, but only once (CHAS FAQ). Alcumus SafeContractor's terms reserve the right to suspend visibility and place a contractor into an 'at risk' status on the client portal where charges aren't paid by the membership renewal date. This is informational only — for anything specific to your account, ask the scheme directly.

Frequently Asked Questions

How long does an SSIP certificate last?

SSIP member scheme certificates typically run for 12 months from the date of issue or assessment. Smas Worksafe, SafeContractor and CHAS all publish a 12-month validity period for their contractor certification, after which a renewal assessment is required.

Does a Deem to Satisfy certificate last 12 months?

No. A Deem to Satisfy certificate expires when the original full SSIP assessment behind it expires, however long is left to run. Smas Worksafe states that six months remaining on your SSIP means six months on your DTS, and SafeContractor says a DTS-based certification is suspended when the original SSIP member certification expires.

Is my accreditation renewal date the same as my payment date?

Often not. CHAS explicitly separates membership expiry, which is the annual payment date, from compliance expiry, which is the annual assessment renewal. Alcumus SafeContractor's contractor terms similarly note that the accreditation review date may not coincide with the membership renewal date, so check both in your portal.

How much notice do I have to give to cancel an accreditation?

SafeContractor states that memberships auto-renew and that you must give at least 14 days' notice before the renewal date to stop it. The CHAS contractor/supplier terms published in 2023 refer to 14 working days' written notice before the next renewal. Notice periods change, so confirm the current wording in your own agreement before relying on it.

Do I need to re-upload the same documents to every scheme each year?

In practice, yes. Mutual recognition covers the health and safety assessment itself, but each scheme holds its own copy of your insurance certificates, policies and training evidence with its own expiry dates. That duplication is the part of the admin that SSIP does not remove — see do I need more than one accreditation for when a second scheme is genuinely unavoidable.
