The NHS tells people they don’t need identification or proof of address to register with a GP.
Recent mystery-shopping research shows what can happen when people actually ask.
There’s a sources section further down this article
For most of us, registering with a GP sounds simple. You contact a surgery, give some basic details and join the list. The NHS has even made the paperwork rules unusually clear.
You don’t need photo ID. You don’t need proof of address. You don’t need proof of immigration status. If you have no permanent address, you can still register.
Then people ring actual surgeries and ask the question the NHS has supposedly settled.
That is where the team here at ReplyResearch became interested, because the answer suddenly depends on who happens to pick up.
The latest warning came from Enfield
On 11 December 2025, Healthwatch Enfield published research after mystery-shopping all 39 active GP practices and interviewing homeless people about the barriers they faced trying to register.
Its conclusion was blunt: “Homeless individuals are wrongly turned away due to lack of ID or a fixed address,” despite NHS guidance allowing registration without either requirement.
Twenty-nine of the 39 practices said they would register homeless people. Others imposed barriers including postcode restrictions and online-only registration, while staff knowledge about homeless people’s registration rights varied considerably.
That matters because homelessness is exactly when neat paperwork falls apart. People sofa-surf, move between temporary addresses, lose documents and rely on services whose rules they may not know.
Then researchers tested ordinary GP registration
One month earlier, on 11 November 2025, The British Medical Journal’s BMJ Open published a peer-reviewed mystery-shopper study involving randomly selected GP practices in Birmingham, Solihull, Herefordshire and Worcestershire.
The researchers created a very ordinary problem. Their caller had recently arrived from Africa, his photo ID was with the Home Office, and he had moved in with his girlfriend.
He had no proof of address in his own name. He simply wanted to know whether he could register with the GP practice he had telephoned.
The study’s answer is extraordinary: “At 46 (54%) of 85 practices, the mystery shopper was refused registration” because he lacked photo ID or proof of address.
The NHS rule isn’t complicated
The NHS registration page, reviewed in July 2025, says adults registering with a GP don’t need ID, proof of address or proof of immigration status.
NHS England’s own primary medical services guidance goes further. It says there is no regulatory requirement to provide those documents and practices should accept people unable to produce them.
Practices can ask for documents for practical reasons, including matching records, but inability to provide them shouldn’t by itself shut the front door on a patient.
Yet in this study, more than half of the practices reached by telephone did exactly what the national rule was designed to prevent: they refused registration over missing paperwork.
The website could be right and the phone still wrong
The researchers didn’t only telephone practices. They checked the practices’ own websites first, which exposed another problem for anybody trying to work out what the rules actually are.
Across websites and telephone calls, 60 of the 85 practices, or 71 per cent, breached NHS guidance somewhere. Only 25 practices followed it consistently across both channels.
At 31 practices, representing 36 per cent of the sample, the information given by telephone contradicted what appeared on the practice website. The institution could disagree with itself.
That is a particularly nasty form of unresponsiveness. A person can read the published instructions, do exactly what they say, then phone the same organisation and be told something different.
Some practices couldn’t be reached at all
The researchers originally sampled 100 practices. After excluding those without usable website information, they attempted to telephone 93, but eight never answered despite repeated attempts.
They didn’t ring once and give up. Each practice was tried on three different days, with callers waiting up to five minutes each time before making a fourth attempt.
On that fourth attempt, researchers waited for as long as 20 minutes. Eight practices still couldn’t be reached, so their registration advice couldn’t even be tested.
For ReplyResearch, that detail matters. Before the researchers could discover whether the front door gave the wrong answer, they found some front doors that wouldn’t answer at all.
Then came the improvised paperwork
At some practices, staff tried to find a workaround. Three suggested the caller’s girlfriend could vouch for his address, while two suggested bringing proof carrying the girlfriend’s name.
Three practices suggested bringing an addressed parcel. Another said a letter showing an address in another country might do. Thirteen simply advised waiting until some suitable documentation arrived.
This is where the whole thing becomes absurd. The NHS rule exists precisely because people may legitimately lack conventional paperwork, yet some callers were sent hunting for substitute pieces of paper.
Four practices advised the caller to try another local surgery. One suggested phoning NHS 111 and another suggested urgent care instead of simply applying the registration rule correctly.
One caller got a very different kind of answer
The researchers used two mystery shoppers, one with a West Midlands English accent and another with a Nigerian accent. Their accents didn’t significantly affect whether documentation was requested.
But some comments about coming from another country were made only to the Nigerian-accented shopper. One practice justified its policy by saying “the system can be abused”.
At another practice, after the caller explained that his passport was with the Home Office, he was asked how he had entered the country in the first place.
The researchers were careful not to claim that this proved widespread racial discrimination. Their stronger finding needs no embellishment: ordinary registration enquiries were producing barriers that contradicted NHS guidance.
Barnet found much the same thing
Healthwatch Barnet had already tested all 48 GP surgeries in that borough, publishing its findings on 22 September 2025 after researchers posed as patients wishing to register.
When asked about proof of address, “55% incorrectly stated that proof was needed”. Only 37 per cent of receptionists clearly said patients could register without providing it.
The same exercise found 33 per cent incorrectly saying proof of immigration status was required, while 57 per cent said patients could only register online rather than in person.
These are separate local studies using different samples and methods, so they don’t prove that every GP surgery in England behaves this way. They do make dismissal considerably harder.
The people who need the rule most
The paperwork rule isn’t some obscure technical favour for people who forgot their wallet. It protects people whose lives don’t produce the tidy documents institutions like to request.
That includes homeless people, people in temporary accommodation, recent migrants and people moving suddenly between addresses. They are also less likely to know the exact NHS rule before making contact.
So the burden quietly shifts. Instead of the institution knowing its own entry rules, the individual may need enough knowledge and confidence to challenge the person refusing them.
If they don’t know the rule, an incorrect answer can simply become reality. They are told they can’t register, and many will have no reason to suspect otherwise.
The NHS has already written the correct answer
The maddening part is that there is no policy vacuum here. The NHS has already decided the question and published the answer in language almost anybody can understand.
Its current public guidance says: “You don’t need ID, proof of address or proof of immigration status.” A person without a permanent address can use a temporary address.
NHS England also tells practices that someone without personal identification, an NHS number or proof of address can still be registered, including by using the surgery’s own address.
The information exists. The problem exposed by these mystery shoppers is what happens when a real person actually approaches the institution and asks somebody to apply it.
This is what institutional unresponsiveness looks like
Unresponsiveness doesn’t always mean silence. Sometimes somebody answers promptly, listens to your question and gives you a confident answer that prevents you doing something you are entitled to do.
That can be worse than no reply because it closes the enquiry. A caller who trusts the surgery may never complain, never escalate and never discover that the answer was wrong.
The BMJ researchers called unnecessary administrative barriers like these “sludge”. That is the academic term. From the patient’s side, it is simpler: you asked to get in and were stopped.
And this is why the story matters beyond GP registration. Institutions increasingly publish polished rules online while the person contacting the institution encounters something quite different at the human front door.
The real scandal is at the front door
Nobody should pretend these studies establish a national refusal rate. The BMJ sample covered 85 successfully contacted West Midlands practices, Barnet covered 48 surgeries and Enfield covered 39.
But that limitation can’t rescue what actually happened. Researchers repeatedly made the sort of enquiry an ordinary person makes, and substantial numbers of surgeries gave answers contradicting NHS registration rules.
The NHS says you don’t need ID or proof of address to register. The person answering the telephone shouldn’t require the patient to arrive knowing that fact already.
Because once patients have to teach an institution its own rules before they can use its services, the institution has shifted its job onto the very people asking for help.

This Footnote Zone uses NokNok’s diagnostic toolkit to examine how the responsiveness failures and inaccessible service journeys described in this article can be identified, measured, and addressed.
- Email Finder: Identifies the friction of user requests existing simultaneously in form databases without accountable human contact options, and scans an organization’s website and related public-facing materials for published email addresses, then reports on structural deficiencies, discrepancies, missing contact routes, or other contactability gaps.
- Reply Radar: Targets the failure of service teams to meet response deadlines and manage human queues, such as the dyslexic claimant whose promised contact never came for fourteen months, and deploys targeted test emails and quantitatively measures reply rates, latency, response consistency, and related responsiveness benchmarks.
- Compliance Sniffer: Addresses the unreliability of current automation agents, including grounding errors and failures to meet legal service outcome expectations, and analyzes incoming responses for objective quality, clarity, relevance, escalation, and compliance benchmarks.
- Mystery Shopper: Audits the complete service journey from first contact through response, adaptation, action, and recovery to prevent systemic end-to-end contact failures, and executes a comprehensive end-to-end responsiveness UX audit, testing how a real user experiences the organization’s contact, response, and escalation pathways.
