Maximus customer portal: an ND-friendly walkthrough

If you've been awarded Access to Work support, there's a good chance you've been pointed at the Maximus customer portal. It's the system Maximus, one of the providers contracted by the DWP, uses to handle claims, evidence and reporting.

It does the job. But it isn't always intuitive, the language is dense, and if you're already navigating ADHD, autism or executive dysfunction, the admin can quickly tip into overwhelm. This is a plain-English walkthrough of the bits that trip people up most.

What the Maximus portal is

The Maximus customer portal is the online system you use to manage the day-to-day admin of your Access to Work award - submitting invoices, uploading evidence of payment, and keeping a record of claims. If Maximus is your assigned provider, this is where most of your reporting will live.

New to the scheme entirely? Start with our overview of Access to Work, demystified first.

Logging in (the Maximus login bit)

Your login details are sent by Maximus after your award is set up. They usually arrive by email and include a username and a temporary password to reset on first sign-in.

If you can't find them:

• Check spam and promotions folders - the welcome email often lands there.
• Search your inbox for "Maximus", "Access to Work" and the email address of your contact at the provider.
• If you genuinely can't find anything, ring or email your Maximus contact and ask them to resend. This is a normal request - they deal with it constantly.

Save the login URL the moment you have it. Trying to find the right Maximus login page through a search engine later is one of the easiest ways to lose half an hour.

Uploading evidence and invoices

The portal expects two things for most claims: an invoice from your support provider, and proof that you've paid it. That's usually a bank statement screenshot or a remittance.

A few things that quietly cause rejections:

• Dates on the invoice and the payment don't match the claim period.
• The payee name on the bank statement doesn't match the invoice.
• Files are uploaded in the wrong slot (invoice in the "evidence of payment" field, or vice versa).
• PDFs that are password protected or larger than the portal's file size limit.

A simple folder per claim period, with the invoice and the payment proof named clearly, saves a lot of pain. "2026-06 invoice.pdf" and "2026-06 payment.pdf" is plenty.

Tracking claims and payments

Once a claim is submitted, the portal will show it as in progress, approved or queried. Two things worth knowing:

• "Approved" doesn't always mean "paid". Payment can take a further few weeks.
• Queries from Maximus often arrive by email rather than in the portal - keep an eye on both.

If something has been sitting for longer than feels reasonable, follow up. A short, polite chase by email referencing the claim reference number usually moves things along.

The honest bit

The portal is workable, not joyful. If admin is the part of your brain that absolutely refuses to engage, you have options. You don't have to do the Maximus side on your own - this is exactly the kind of work an Access to Work support worker can be funded to help with.

If you'd like a human in your corner for this, that's what our Access to Work support is for.
