Received a Parking Charge Notice from GroupNexus? You are not automatically liable just because a notice arrived — private parking charges are invoices, not government fines, and they are challenged successfully every day. You normally have 28 days to lodge a challenge, so act early. This guide covers the official appeal route, the grounds that actually work, and the evidence to attach. When you are ready, the free Parksy fine appeal letter generator reads a photo of your notice and drafts the letter for you — no sign-up needed to start.
⏱ Deadline: 28 days from the date of the notice

Grounds to appeal a GroupNexus Parking Charge Notice
Appeals built on one specific, evidenced ground beat generic complaint letters. The strongest grounds are:
- The signage was missing, unclear, or did not form a proper contract (entrance signs unreadable from a moving vehicle)
- You were within a grace period — BPA members must allow at least 10 minutes after a paid/permitted period ends
- The Notice to Keeper did not meet POFA 2012 Schedule 4 requirements (wrong timing, missing wording), so keeper liability fails
- The machine or app was out of order and no alternative payment method was available
- You were a genuine patron and the operator can verify it (receipts, witness) — mitigating circumstances
- The ANPR record is wrong: double visits read as one long stay, or plate misread
- You had a valid permit, Blue Badge, or authorisation that was displayed or registered
- The charge is disproportionate and does not reflect a genuine pre-estimate of loss for the alleged breach
How the GroupNexus appeal process works
GroupNexus is the trading name of CP Plus Limited, formed in 2018 from the merger of CP Plus, Ranger Services and Highview Parking. It manages more than 1,200 parking sites across the UK for landowners including NHS hospitals, retail parks, universities and railway stations, relying heavily on ANPR camera enforcement. Tickets can arrive branded GroupNexus, CP Plus or Highview Parking — all lead back to the same company. It is a BPA Approved Operator (listed as 'CP Plus Limited t/as Group Nexus'), so second-stage appeals go to POPLA.
Appeal within 28 days of the Parking Charge Notice via the online portal at nexusplatform.co.uk/pcn — GroupNexus requires appeals in writing and will not take them by phone — or by post to Jack Straws Castle, 12 North End Way, London, NW3 7ES. Include the PCN number, vehicle registration, your grounds (payment proof, unclear signage, hospital-visit circumstances, POFA non-compliance) and supporting evidence. Do not pay first, as payment ends the dispute. GroupNexus says a response can take up to 28 days.
If the appeal is rejected, the rejection letter gives you a POPLA code valid for 28 days; POPLA is free and its decision binds the operator but not you. Under the BPA code a rejected first appeal made within 14 days normally triggers a re-offer of the discounted rate. Unpaid charges are passed to debt-recovery agents and can end in County Court claims.
Evidence to include
- Photos of the signage as you saw it — position, height, legibility (wide shots and close-ups)
- Your ticket, permit, receipt, or app payment confirmation
- Photos of the location, bay markings, and any machines (including error screens)
- The notice itself, both sides
- Witness statements if someone was with you
- Breakdown/recovery or medical documentation where relevant
Unsure what the signs at the site actually permit? Photograph them and run them through the free Parksy parking sign scanner — it decodes the restrictions in plain English, which often reveals the exact defect your appeal should lead with.
What if GroupNexus rejects your appeal?
A first-stage rejection is not the end of the road. You can escalate to POPLA, which is independent of GroupNexus and free for motorists to use. Escalation deadlines are stated in the rejection letter — diarise them the day it arrives, and reuse your original evidence with any gaps the rejection pointed out now fixed.
The law behind it
Frequently asked questions
Who are GroupNexus and why have they sent me a Parking Charge Notice?
GroupNexus is the trading name of CP Plus Limited, one of the UK's largest private parking operators, created in 2018 when CP Plus, Ranger Services and Highview Parking merged. It manages over 1,200 sites for landowners in healthcare, retail, education and rail — NHS hospital car parks and retail parks are particularly common. Most of its enforcement is by ANPR cameras that record your vehicle entering and leaving; a Parking Charge Notice is then posted to the registered keeper alleging an overstay, non-payment or keying error. This is a private contractual charge, not a council penalty. You have 28 days to either pay or appeal, and because GroupNexus is a BPA Approved Operator you get access to the free independent appeals service POPLA if your first appeal is rejected. Appeals must be in writing — GroupNexus does not accept challenges by telephone.
How do I appeal a GroupNexus parking charge?
Appeal within 28 days of the notice date. The quickest route is the official portal at nexusplatform.co.uk/pcn, where you enter the PCN reference and vehicle registration and submit your grounds with evidence attached. Alternatively write to GroupNexus at Jack Straws Castle, 12 North End Way, London, NW3 7ES, quoting the PCN number and registration. Strong grounds include proof you paid (bank statement or payment-app record), a keying error where you paid but mistyped the registration, inadequate or unreadable signage, a Notice to Keeper that fails the Protection of Freedoms Act 2012 requirements, or medical emergencies — especially relevant at the NHS hospital sites GroupNexus manages. Do not pay before appealing, because payment closes the case and removes your right to challenge. GroupNexus states its appeals team can take up to 28 days to respond, during which the charge is on hold.
My ticket says Highview Parking or CP Plus — is that the same as GroupNexus?
Yes. CP Plus Limited (company number 2595379) trades as GroupNexus, and Highview Parking and Ranger Services were folded into the same group in the 2018 merger. Highview Parking Limited still appears separately on the BPA Approved Operator list and some sites still issue tickets under the Highview or CP Plus branding, but the back office, appeals handling and postal address are shared, and Highview appeals are directed through the GroupNexus platform. Whichever brand appears on your notice, the process is the same: appeal in writing within 28 days via nexusplatform.co.uk/pcn or by post to the London NW3 address, quoting the exact reference on your notice. Because all these brands operate under BPA membership, a rejected first appeal comes with a POPLA code for a free, independent second-stage appeal within 28 days.
What happens if GroupNexus rejects my appeal?
The rejection letter must include a 10-digit POPLA verification code and explain that you have 28 days to lodge a free appeal at popla.co.uk. POPLA (Parking on Private Land Appeals) is independent of the operator: it reviews evidence from both sides and its decision is binding on GroupNexus but not on you, so even if you lose at POPLA you can still refuse to pay and defend any subsequent County Court claim. Under the BPA code, if your first appeal was made within 14 days of the notice, GroupNexus should normally re-offer the discounted rate (typically 40% off) for a further 14 days after rejection, so appealing early carries little financial risk. If you neither pay nor escalate, expect debt-recovery letters with added 'costs' and, potentially, a court claim — respond to any claim form within the court deadlines.
I got a GroupNexus ticket at a hospital — do I still have to deal with it?
Yes, but hospital tickets are often the most winnable. GroupNexus manages many NHS hospital car parks, and both the BPA code and NHS guidance require operators to show leniency toward patients and visitors delayed by treatment, emergencies or discharge waits. In your appeal, explain the medical circumstances and attach whatever you can: appointment letters, discharge paperwork, a ward or department confirmation, or proof you paid for part of the stay. Keying errors at hospital payment machines (entering one wrong character of your registration) are another common and frequently successful ground. Appeal within 28 days through nexusplatform.co.uk/pcn rather than ignoring the notice, because unpaid hospital-site charges are pursued the same way as any other — debt collectors, then possible court action. If GroupNexus still rejects a reasonable hospital appeal, escalate to POPLA, which regularly allows appeals where operators failed to consider mitigation required by their own code.
