Test Centre or In-House System? How to Know Which One Is Right for Your Business
Let's start with something you might not expect a pressure testing equipment manufacturer to say:
For many companies, using a test centre is absolutely the right call.
The decision between sending your products to an external test facility and investing in your own in-house system is one that depends entirely on your situation, your volumes, your development stage, your budget, your timelines, and how central pressure testing is to what you do. There's no universal right answer, and anyone who tells you otherwise is trying to sell you something.
What we can do is lay out the honest pros and cons of each approach, so you can make a genuinely informed decision. And if that decision is "test centre for now," that’s okay because we will still be here when the time is right.
So let's get into it…
Option 1: Using an External Test Centre
Facilities like Balmoral Comtec in Aberdeen or the Tyne Pressure Testing in the Tyne & Wear offer access to high-specification hyperbaric and pressure testing equipment on a day-rate or project basis. You bring your product, they run the test, you get your results.
The Pros
Low upfront cost You're not buying anything. You pay for what you use, when you use it. For a company that needs one or two tests a year, this can make excellent financial sense.
Access to high-end capability Test centres often have equipment that would be prohibitively expensive to own outright, very large chambers, extreme pressure ratings, specialist ancillaries. If you occasionally need something outside the ordinary, a test centre gives you access.
Someone else maintains it Calibration, maintenance, certification, Written Scheme of Examination, compliance… that's all the test centre's problem. You show up, you test, you leave.
Useful for early-stage development If you're still working out what you're building and how often you'll need to test it, using a test centre while you find your feet is a perfectly sensible approach. Committing to a capital purchase before you understand your testing needs can be a frustrating mistake.
The Cons
You're on their schedule, not yours Test centres are busy. Getting a slot at short notice, especially at peak times can be difficult. If you're working to a tight development timeline, waiting two weeks for a test slot is genuinely painful. And if the test reveals a problem and you need to retest after a design change, that's another wait, not to mention your busy time is often everyone else’s too and we are all fighting for the same resource.
Travel, logistics, and downtime Getting your product to a test centre, particularly if it's at an early prototype stage, fragile, or large — takes time and money. And while it's being tested elsewhere, it's not at your facility. That sounds obvious, but the cumulative impact on project timelines is often underestimated.
Day rates add up faster than people expect A single day at a test facility might seem manageable. But by the time you've factored in mobilisation time, setup, the test itself, any repeat runs, and demobilisation, a "day's testing" has a habit of becoming two or three days. Do that several times across a development programme and the costs start to look rather different.
Limited flexibility for iterative testing If your development process involves lots of test-adjust-retest cycles, which in our opinion the best engineering usually does, the logistics of using an external facility can slow that process to a crawl. Every iteration means another booking, another trip, another delay.
Confidentiality considerations This one doesn't apply to everyone, but it's worth thinking about. If you're testing something commercially sensitive or proprietary, you're taking it to someone else's facility, potentially alongside other companies' work. Most test centres take confidentiality seriously, but you cant help being in the same room as your competitors so it's a consideration.
Option 2: Investing in Your Own In-House System
At the other end of the spectrum, you invest in your own pressure testing equipment, whether that's a benchtop hyperbaric chamber, a full hydrostatic pressure test system, or something bespoke to your application and bring the capability in-house permanently.
The Pros
Test whenever you want This is the big one. When the test equipment is in your facility, you test on your timeline. Tuesday at 7am before a client call? Fine. Three times in one day because you're iterating quickly? No problem. No booking forms, no waiting for availability, no travelling.
Faster development cycles The ability to test, review results, make changes, and retest — all within the same facility, potentially the same day — can dramatically accelerate product development. For companies where time-to-market matters, this is where in-house testing really earns its keep.
The economics improve with volume A bespoke system from J Pope Solutions is a capital investment, but it's one that pays back over time. The more you test, the better the economics look relative to day-rate facility costs. Many of our customers find that their system has effectively paid for itself within a year, sometimes faster.
Your IP stays in your building Everything about your product, your test parameters, and your results stays within your four walls. No third-party involvement, no confidentiality concerns.
Tailored exactly to your needs An off-the-shelf chamber from a test centre is designed to cover as many use cases as possible. A bespoke system from us is designed around your products, your test requirements, and your workflow. That means it fits better, works better, and is easier for your team to use.
Build internal expertise Running your own testing programme builds knowledge within your team. Your engineers develop an intuitive understanding of how your products behave under pressure, which feeds back into better designs. That's hard to quantify but genuinely valuable.
100% product testing Give your customers supreme confidence by letting them know every single product is tested before it leaves you, what’s more reassuring than knowing a product has seen the harshest conditions it will ever endure and functionally tested before it even arrives.
The Cons
Upfront capital cost There's no getting around this one. Even a benchtop system represents a meaningful capital investment. For businesses at an early stage, or where testing volumes are low, that upfront cost can be hard to justify.
You own the maintenance Calibration, servicing, certification, compliance, that's now your responsibility. For most companies this isn't a major burden, but it's worth factoring in and of course J Pope Solutions can handle this for you.
You need the space Obvious, but worth saying: a pressure testing system needs somewhere to live. If your facility is already bursting at the seams, that's a real constraint.
It's a commitment Buying a system means committing to a particular set of requirements. If your product or testing needs change significantly, your system may need modification. Bespoke systems can usually be adapted, but it's not the same flexibility as just booking a different test centre.
So How Do You Decide?
Here are the questions worth asking yourself honestly:
How often do you test? If it's fewer than a handful of times a year, a test centre probably makes more sense for now. If you're testing regularly, monthly, weekly, or more, the economics of in-house start to look compelling.
How important is speed of iteration to your development process? If you're in a fast-moving development programme where you need to test and retest frequently, the logistics of external testing will cost you time you can't afford. In-house wins here.
Are you at an early or mature stage of product development? Early stage, uncertain requirements, low volumes: test centre. Mature, established product line, predictable testing needs: in-house.
Is your product commercially sensitive? If yes, in-house is worth serious consideration.
What does your three-to-five year picture look like? Even if a system is hard to justify today, if your testing volumes are growing, it's worth doing the maths on when the crossover point arrives, especially to keep in mind that while a small 300mm vessel can be ready in around 8-12weeks, a 1000mm diameter x 3000mm deep vessel may take 30-50 weeks… that’s right it could take almost an entire year to get delivered, so its worth thinking ahead.
The Honest Answer
Many of our best customers spent time at test centres before coming to us — and that's completely fine. It's often exactly the right sequence. External facilities let you validate your testing needs before committing to a capital purchase, and the experience of using them usually gives you a very clear picture of what you'd want from an in-house system.
If you're at the point where you're asking the question — "should we be doing this ourselves?" — it's probably worth a conversation. Not because the answer is definitely yes, but because talking it through with someone who understands the options is usually the fastest way to get to the right decision.
We're happy to have that conversation with no agenda other than helping you work it out.
