If you’ve spent even ten minutes searching for a door supervisor course in London, you’ve probably noticed something strange. One provider quotes £150. Another quotes £350. A third throws around numbers like £550 for something they call a “premium package.” Same qualification. Same regulator. Wildly different prices.
So what’s going on? Is the cheap course a scam? Is the expensive one just better marketing? Or is there something in the fine print that explains the gap?
This guide breaks down exactly what you’re paying for when you book a door supervisor course, what’s usually bundled into the headline price, what almost always costs extra, and how to avoid paying twice for something that should have been included the first time. By the end, you’ll be able to look at any quote and know within seconds whether it’s a fair deal or a trap.
What Is a Door Supervisor Course, Exactly?
Before we talk about money, it helps to be clear on what you’re actually buying.
A Door Supervisor course is the mandatory training you need before you can apply for an SIA (Security Industry Authority) Door Supervisor licence. Without this licence, you cannot legally work on a door, at a nightclub, bar, event, retail site, or anywhere else that requires door supervision in the UK.
The course itself is a nationally recognised qualification, usually delivered over several days, and typically covers:
- The role and responsibilities of a door supervisor
- Health, safety, and welfare in the workplace
- The private security industry and its legal framework
- Licensing law relevant to licensed premises
- Recognising and reducing conflict
- Physical intervention skills
- Emergency procedures and first aid basics (in many course structures)
At the end of the course, you sit a set of assessments — usually multiple-choice exams plus a practical assessment — and if you pass, you receive a certificate that lets you apply to the SIA for your licence.
That part is the same everywhere. What varies wildly is everything wrapped around it — and that’s where the price differences come from.
The Real Price Range for a Door Supervisor Course in London
Across London training providers, you’ll typically see door supervisor course fees land somewhere between roughly £150 and £350, with some providers pricing slightly higher when extras are bundled in. A small number of “premium” providers charge more, usually justified by smaller class sizes, evening or weekend flexibility, or add-ons like guaranteed job referrals.
There is no single “correct” price. But there is a correct question to ask before you book: what does this number actually include?
Because a £150 course that excludes First Aid, excludes exam resits, and excludes your registration paperwork can end up costing more than a £280 course that includes all three. The headline number means very little on its own.
What’s Usually Included in the Course Fee
Here’s a breakdown of what a typical door supervisor course fee should cover, assuming you’re booking with a legitimate, SIA-approved training provider.
1. The Core Training Days
This is the non-negotiable part. Most Door Supervisor courses run across multiple days (commonly around six days of contact time, sometimes compressed into an intensive schedule). This is the actual classroom or virtual-classroom teaching: conflict management, physical intervention, licensing law, and the rest of the syllabus. This is always included in the base fee — no provider can legally sell you a “training course” without the training itself.
2. Course Materials
Workbooks, handouts, and reference materials used during the sessions are typically part of the package. Some providers now deliver these digitally rather than as printed booklets, which slightly lowers their costs — one reason online-supported providers can sometimes price a little lower than fully in-person ones.
3. The Exams
At the end of the course, you’ll sit a series of multiple-choice tests plus a practical assessment. The first attempt at these exams is included in your course fee at almost every reputable provider. This is standard — you shouldn’t be paying extra just to sit the assessment for the first time.
4. Your Certificate on Completion
If you pass, you’ll be issued a certificate confirming you’ve completed the qualification. This certificate is what allows you to apply to the SIA for your licence. It’s part of the course fee — but be aware that turnaround time for receiving it varies by provider, and delays here can hold up your licence application.
5. First Aid Training (Sometimes)
This is one of the biggest variables between providers. Some Door Supervisor course structures require you to hold a valid Level 3 Emergency First Aid at Work certificate before you even start the security training — and if you don’t already have one, some providers include a day of First Aid training within the course package, while others expect you to arrange and pay for it separately.
This single difference can explain £50–£100 of the gap between two otherwise similar-looking quotes. Always ask directly: “Is First Aid included, or do I need to source it myself?”
6. Trainer-Led Support During the Course
A properly accredited course includes access to a qualified trainer throughout — someone who can answer questions, run through practical scenarios, and prepare you for the assessment. This is baked into the price and isn’t usually itemised separately, but it’s worth remembering that the quality of this support is one of the biggest differences between a “cheap” course and a “cheap and rushed” course.
What’s Almost Never Included (Read This Before You Book)
This is the part most people miss — and the part that causes the most frustration after the fact. The course fee gets you trained and certified. It does not, in most cases, get you licensed. Those are two separate steps with two separate costs.
1. The SIA Licence Application Fee
Once you’ve passed your course, you still need to apply to the SIA directly for your licence. This application has its own non-refundable fee, paid straight to the SIA (not to your training provider), and it currently sits at £204. No training provider fee — however expensive — includes this, because it’s a separate government-regulator charge, not a course cost. Budget for it separately from day one.
2. Identity and Right-to-Work Documentation
You’ll need to prove your identity and your right to work in the UK as part of your licence application. If you need to obtain or renew any documents to do this (passport, visa evidence, etc.), that’s on you, not the training provider.
3. Criminal Record Checks
Part of your SIA application involves background checks. These are handled through the application process itself, but it’s worth knowing this step exists and can occasionally introduce delays if your history needs extra verification.
4. First Aid (If Not Bundled)
As mentioned above — if your chosen course doesn’t include this, you’ll need to book and pay for a separate First Aid qualification before your training can begin or before your licence application will be accepted, depending on the structure.
5. Exam Resits
If you don’t pass one of the assessments on your first attempt, most providers charge an additional fee for a resit. This varies by provider — some charge a flat resit fee, others charge per module. Ask about this upfront, especially if you’re nervous about exams, because it can turn a “cheap” course into an expensive one if you need to retake something.
6. Uniform, ID Badge Holders, or Job-Readiness Extras
Some providers upsell add-ons like CV support, interview prep, or “guaranteed job placement” packages. These aren’t part of the statutory course and are entirely optional — useful for some people, unnecessary for others, but always worth knowing they’re an add-on and not a requirement.
Why Prices Vary So Much Between Providers
Now that you know what’s typically in and out of the base fee, here’s why the same qualification can be priced so differently across London providers.
Location and venue costs. A course delivered in Central London or Canary Wharf often costs more to run than one delivered in an outer borough, simply because of venue hire. This gets reflected in the price.
Class size. Smaller groups mean more individual attention from the trainer, which usually means a higher price. Larger groups keep costs down but can mean less hands-on support during practical sessions.
Delivery format. Fully in-person courses tend to cost more than blended or virtual-classroom formats, where some theory is delivered online and practical sessions happen in person.
What’s bundled in. As covered above, First Aid inclusion, materials, resits, and support services all shift the final number.
Provider reputation and pass-rate support. Some providers invest more in trainer quality and exam preparation, which shows up in both price and pass rates. This doesn’t mean the most expensive option is automatically the best one — but it does mean a rock-bottom price sometimes correlates with a rock-bottom level of support.
Accreditation overhead. Legitimate providers pay ongoing fees to maintain their SIA-approved training status and awarding body accreditation. This is a fixed cost of doing business properly, and it’s baked into every legitimate quote you’ll see.
Red Flags to Watch For When Comparing Quotes
Because the price gap is so wide, it’s worth knowing what to be cautious of:
- A price that seems too low with no explanation. If a course is priced dramatically below the local market average, ask what’s excluded. Sometimes it’s a genuine introductory offer. Sometimes it’s a stripped-down package with resits, materials, or First Aid all charged separately later.
- No mention of SIA approval or accreditation. Any legitimate Door Supervisor course must be delivered by an SIA-approved training provider. If this isn’t clearly stated, ask directly before paying anything.
- Vague answers about what’s included. A provider that can’t clearly tell you whether First Aid, materials, and a first exam attempt are included is a provider you should be cautious about.
- Pressure to pay a large deposit immediately. Reputable providers are usually happy to answer questions and let you compare before committing.
- No clear cancellation or rescheduling policy. Life happens. A provider without a clear, written policy on this can leave you out of pocket if you need to move your dates.
A Simple Way to Compare Two Quotes Side-by-Side
When you’re looking at two different course prices, run them through this checklist:
- Does the price include the full training days, or is it a partial/introductory rate?
- Is First Aid included, and if so, is it a recognised Level 3 Emergency First Aid at Work qualification?
- Is the first attempt at all exams included?
- What does a resit cost, if needed?
- Is course certification and support with the SIA application process included?
- Is the provider clearly listed as SIA-approved?
- What’s the cancellation/rescheduling policy?
- Are there hidden admin or registration fees on top of the headline price?
Once you answer these eight questions for two competing quotes, the “cheaper” option often stops looking cheaper — or the “expensive” one starts looking like much better value.
This is exactly the kind of transparency worth looking for before you book. Training providers who lay out their inclusions clearly — for example, BeTrain’s Door Supervisor course page — make it much easier to see what you’re paying for before you hand over a deposit, rather than discovering the gaps after you’ve already started.
A Realistic Cost Breakdown for London
To put real numbers around this, here’s a rough picture of what a Door Supervisor journey typically costs from start to finish in London, based on common provider structures:
| Item | Typical Cost |
|---|---|
| Door Supervisor course fee | Roughly £150–£350 |
| First Aid (if not bundled in the course) | Roughly £50–£100 |
| SIA licence application fee (paid to SIA directly) | £204 |
| Exam resit (if needed) | Varies by provider, ask before booking |
| Estimated total to become licensed | Roughly £400–£650 |
These figures are general industry ranges, not fixed prices — always confirm the current fee directly with your chosen provider and check the SIA’s own site for the latest licence application cost, since regulatory fees can be updated.
Why the “Cheapest Course” Isn’t Always the Cheapest Route to a Licence
Here’s the practical takeaway: the number on the homepage is not the number that matters. What matters is the total cost of getting from “unlicensed” to “working legally as a door supervisor” — training, First Aid, exams, resits if needed, and the SIA application fee.
A course priced at £180 that excludes First Aid and charges £60 for a resit could easily end up costing more than a £280 course that includes both. Read the inclusions list before you compare prices, not after.
Is It Worth Choosing a Slightly More Expensive Provider?
Sometimes, yes. If a more expensive provider offers:
- Smaller class sizes with more individual attention
- Guaranteed inclusion of First Aid and materials
- A free first resit
- Genuine support navigating your SIA application
- Flexible scheduling that fits around your current job
…then the extra cost can easily pay for itself in time saved, stress avoided, and a better chance of passing first time. Security work is a career where being properly prepared for the practical and conflict-management assessments genuinely matters — not just for passing the exam, but for the job itself.
Final Thoughts
Searching for a door supervisor course in London shouldn’t feel like decoding a puzzle. The training itself is standardised, but how providers package, price, and communicate their fees is not — and that’s exactly where confusion (and unexpected costs) creep in.
Before you book anywhere, get a clear, written answer to these three questions:
- What exactly is included in this price?
- What will I need to pay separately, and when?
- What happens if I need a resit or need to reschedule?
Get those three answers in writing, and you’ll know precisely what you’re paying for — and you’ll avoid the single most common complaint people have after booking a door supervisor course: discovering, too late, that the cheap option wasn’t actually cheap at all.
Frequently Asked Questions
1. How much does a door supervisor course cost in London?
Door supervisor course fees in London typically range from around £150 to £350, depending on the provider, class size, location, and what’s included (such as First Aid training and exam resits). Always confirm the full inclusions list before comparing prices between providers.
2. Does the door supervisor course fee include the SIA licence?
No. The course fee only covers your training and certification. The SIA licence application is a separate, non-refundable fee paid directly to the SIA, currently set at £204, and is not included in any training provider’s course price.
3. Is First Aid training included in the door supervisor course price?
It depends on the provider. Some Door Supervisor courses bundle in a First Aid qualification as part of the package, while others require you to arrange and pay for it separately before you can complete your licence application. Always ask this question before booking.
4. What happens if I fail the door supervisor exam?
Most providers include your first attempt at the exams within the course fee, but charge an additional fee if you need a resit. Resit costs and policies vary by provider, so it’s worth confirming this detail before you book.
5. How many days is a door supervisor course in London?
Most Door Supervisor courses run across multiple days, with six days of training being a common structure, combining classroom learning, practical conflict management and physical intervention training, and final assessments.
6. Can I get a door supervisor course cheaper if I book online?
Some providers offer slightly lower prices for courses delivered in a blended or virtual-classroom format, since this can reduce venue and printing costs. However, cheaper isn’t always better — check that First Aid, materials, and exam attempts are still included before choosing a lower-priced option.
7. What documents do I need before starting a door supervisor course?
You’ll generally need proof of identity, proof of your right to work in the UK, and in some cases a valid Level 3 Emergency First Aid at Work certificate before starting your training, depending on the provider’s course structure.
8. Why do door supervisor course prices vary so much between providers?
Prices vary based on venue location, class size, delivery format (in-person vs. blended), what’s bundled into the fee (First Aid, materials, resits), and the level of trainer support offered. It’s important to compare what’s included, not just the headline price.
9. Is the SIA licence application fee included in any door supervisor course?
No provider includes this fee within their course price, because it’s paid directly to the SIA as the industry regulator, not to the training provider. Budget for this separately, in addition to your course fee.
10. What is the total cost of becoming a licensed door supervisor in London?
Once you add the course fee, any separate First Aid cost, and the SIA licence application fee, the realistic total to become a fully licensed door supervisor in London typically falls somewhere between roughly £400 and £650, depending on the provider and whether any extras (like resits) are needed.
