How to Choose a Car Park Management Supplier: 10 Questions to Ask
3 proposals sit on the desk, each with a camera specification stapled behind the cover. The site walk is booked for Thursday. Someone on the team has already sketched a shortlist from the hardware and the headline price, because that is the easy part to compare. The harder part sits underneath it. In the UK and Ireland the written rules place duties on the site and on the landowner, not only on the company running the barrier. So the questions that decide how well the next 5 years go are rarely about equipment. They are about who holds the accreditation, who signed the landowner authority, who controls the data and what happens on the way out. Here are 10 to work through before anyone signs.

The 10 questions in one place
These are the 10 questions to put to any car park management supplier before appointing one. They cover accreditation, the 31 December 2026 compliance deadline, landowner authority, data control, appeals, how charges are set, signage, the Irish parking controller duty, what you own on exit, and the commercial model.
None of the 10 concern camera resolution or how many bays fit on the plan. They sit closer to the diligence you would run on any contractor taking on a legal duty alongside you, because that is what appointing a parking access control supplier really is.
A shortlist built on price alone skips all of it. Ask the questions in this order, get the answers in writing, and compare suppliers on the substance of what comes back.
The suppliers worth shortlisting tend to have these documents ready rather than promised. Where an answer needs checking, a second meeting before a first signature costs nothing and settles a lot.
| The question | Why it matters | What a straight answer sounds like |
|---|---|---|
| Which accredited trade association are you a member of, and what is your membership number | Membership decides whether DVLA will release keeper data at all | A checkable membership number held with one of the 2 accredited trade associations |
| How will this site meet the Single Code of Practice by 31 December 2026 | All sites must comply by that date, not only new ones | A written plan tied to specific clauses, not a general reassurance |
| Who holds the written landowner authority, and what does it cover | Charges cannot be issued without it | Names the landowner, the boundary, any byelaws, the duration and the tariffs |
| Who is the data controller for the plate reads, and where is the written data contract | UK GDPR requires a binding written contract with any processor | A contract naming the controller, retention terms and deletion rights, ready to show |
| Which independent appeals service handles a challenge, and who answers it | The appeals route follows the trade association the supplier belongs to | Names POPLA or the Independent Appeals Service, with a named contact |
| How are charges set at this site, and what is the reduction for early payment | The code caps the charge and sets a minimum early payment reduction | A figure inside the cap, with the reduction stated in plain terms |
| What signage goes up, who maintains it, and who pays to change it | Signage is a duty on the site, not only a supplier extra | A maintenance schedule and a clear line on who covers updates |
| If we operate in Ireland, who is the parking controller and who answers appeals in 21 days | The parking controller carries the appeals duty even where clamping is subcontracted | Names the controller and confirms the 21 day turnaround |
| What do we own if we leave, the data, the history and the hardware | Exit terms decide what stays with you and what does not | A written answer covering data export, transaction history and hardware ownership |
| What is the commercial model, and what does the exit look like | The payment structure and the notice period should be settled before signing | A plain description of the model and a stated notice period |
Why accreditation decides what a supplier can actually do
The DVLA will not release keeper data to a parking company outside the 2 accredited trade associations behind the Single Code of Practice, namely the British Parking Association, along with the International Parking Community. Without that membership a supplier cannot trace a vehicle to an address, so plate based charging does not work.
Membership is checkable. Ask for the number and look it up, the same way you would check any other credential before handing over a site.
Membership also brings oversight. Each accredited trade association audits its operators at least once a year, and random site inspections and intelligence led checks can happen outside that annual cycle. A useful follow up: when was your last audit, and what came out of it?
A supplier comfortable naming its association and walking you through its audit history is usually comfortable with the rest of the paperwork, which tends to make the other 9 questions quick work.
What the 31 December 2026 deadline means at site level
The Single Code of Practice sets 31 December 2026 as the date by which all aspects apply to all sites. Parking charges must not exceed £100, a reduction of at least 40% must be offered for payment within 14 days, only 1 charge may be issued per parking event per day, and an entrance sign must be displayed and maintained.
Those terms reach existing sites, not only new ones, once the transition period closes. Where a charge relates to an unpaid tariff rather than a breach of the terms, up to an additional £60 may be added to that tariff, so how a charge is categorised at the point of issue is worth understanding early.
The entrance sign is a small physical thing to check on a site walk and it carries real weight. It has to be there and it has to stay legible, which makes it a maintenance job as much as an installation one. Clear signage is part of being compliant, not only part of looking the part.
A statutory code is also on the way. In a written answer on 20 May 2026 the Ministry of Housing, Communities and Local Government said the government is committed to publishing its new Private Parking Code of Practice in Autumn 2026, which is worth allowing for in any contract signed this year.
Who holds the landowner authority
Before an operator issues a single charge, the code requires written confirmation from the landowner. It covers the identity of the landowner, a boundary map of the land to be managed, any byelaws that apply, the permission granted and its duration, and the parking terms, including how long free parking runs and the tariffs after that.
A boundary map is easy to produce and easy to get wrong. Walk the line against the plan before anyone signs, because a car park that has gained a bay or lost a corner over the years rarely matches the drawing in the file.
The same document should say plainly how long a visitor can stay before anything is payable, and what applies after that. Loose wording at this stage causes more disputes on a site than any camera fault ever will.
References help too. Ask for a site the supplier already runs and speak to whoever manages it, because a landowner living with the arrangement day to day will tell you things a proposal never will.
Walk the site with us
Parka will walk the boundary with you, check it against the landowner authority, and confirm what the signage and access setup need to cover before anything is signed.

Who controls the data, and what happens to it
UK GDPR requires a binding written contract wherever a processor handles personal data for a controller, covering the purpose, the data types, security, sub processors, deletion or return at the end of the service, and audit access. Parking charge records are kept for 36 months, with a unique identifier, date, time, location, reason and status.
Ask which party is the controller and which is the processor, and get the split written down rather than assumed. It decides who answers a request from an individual about their own information, and who carries the duty for how that information is stored and removed.
None of this is about watching drivers. The value sits in the aggregate: occupancy by hour, how long visits actually last, how many charges are challenged and why. Good reporting and data turns a car park from a guess into something you can plan staffing and pricing around.
Ask what happens at the end of the contract as well as during it. A supplier should be able to say plainly whether records are deleted, returned to you, or passed to whoever takes over, and how long that handover takes.
Appeals, and the second jurisdiction
In the UK an appeal goes to Parking on Private Land Appeals, known as POPLA, for British Parking Association members, and to the Independent Appeals Service for International Parking Community members. In Ireland an appeal may be lodged in writing within 60 days, with a determination due within 21 calendar days of lodgement.
The Irish code puts that appeals duty on the parking controller, and it holds irrespective of a clamping operator's involvement. That is why it recommends a formal documented agreement between the two, setting out the precise boundaries of the clamping place and the specific activities the clamping operator will carry out.
Signage sits in the same place. The parking controller has a fundamental legal responsibility to install sufficient, legible clamping information signage throughout each clamping place, and to keep it that way. Where the clamping place is not a statutory one, the charge for removing a clamp and nothing more is capped at 125 euro.
So before appointing anyone, ask the plain questions. Who is the parking controller here? Who puts the signs up? Who answers the appeal, and inside what window? The pattern repeats across both jurisdictions: the duty sits with the site, and a supplier's job is to help you meet it rather than to carry it away.
The commercial model, and the exit
Parka fits the commercial model to the site rather than the other way round: rent the hardware and software, buy the hardware outright, a per transaction revenue share, or a flat fee. Most operators pay little to nothing out of pocket, because we aim to earn only when your car park earns. Ask every supplier the same question.
Talk to our team about which model offsets the setup, whether the site needs ANPR cameras and barriers and access control working together at the entrance, kiosks for visitors who prefer to pay at a machine, or digital signs on the approach. Parka supplies and supports the whole suite, so the answer can be shaped around the site rather than around one product.
Buying and running all of it yourself is a serious undertaking. The cameras, the barrier, the payment equipment, the signs and the software behind them each carry their own cost and their own maintenance, which is why the commercial model matters more than the sticker on any single item. Money a car park earns then goes back into the ground it came from: resurfacing, lighting, better signs, security and EV charging the site could not otherwise fund.
The exit deserves the same attention as the start. Ask for the notice period, what happens to the hardware, and how the transaction history is handed back, in writing, before anything is signed.
Bring the 10 questions to the first proper conversation and most of this is settled in one sitting. Let the answers pick the shortlist, and the site inherits a supplier it can still work with in year 5.
Common questions
How long do we have to comply with the Single Code of Practice?
All aspects of the code must be complied with, for all sites, by 31 December 2026. That date comes from the code's own transition table and it applies whether the site is new or has been running for years. A supplier worth shortlisting will already have a written plan for reaching it.
Why does trade association membership matter when choosing a supplier?
The DVLA will not release vehicle keeper data to a parking company outside the 2 accredited trade associations. Membership of either the British Parking Association or of the International Parking Community is a practical requirement rather than a badge, because without keeper data a plate based charge cannot be followed up. Ask for the number and check it.
Who is responsible if a clamping decision in Ireland is appealed?
The parking controller is primarily liable for compliance with the appeals procedures, even where a separate clamping operator does the day to day work. An appeal may be lodged in writing within 60 days, and a determination must be given within 21 calendar days of lodgement. That duty stays with the site.
What should an exit clause in a car park management contract cover?
The notice period, what happens to the hardware on site, and how the transaction history and records are exported or handed back. None of it is an unusual thing to ask for. A supplier confident in its own service can put clear exit terms in writing before the contract is signed.
