Questions we get asked
The American site answers American questions — CAGE codes, DFARS, federal registrations. None of those are what gets asked here, so these are the British ones.
Buying from Intepro in Britain
- Who am I actually contracting with?
- Intepro UK Limited, company number 05766149, registered in England and Wales since April 2006, with its registered office in Sandhurst. It is a British company, not a branch office, so a British purchase order, British contract law and a British bank account all apply normally.
- Do you sell Delta Elektronika, Cinergia or EA Elektro-Automatik?
- Not in Britain. Intepro is the North American distributor for those manufacturers; here, Delta is held by Telonic Instruments and Cinergia and EA by Caltest Instruments. We design and build test systems around that equipment, and we say so on every page that mentions it. If you want the instrument itself, those firms will serve you better and we would rather tell you than take the enquiry. More on this.
- Are you VAT registered?
- Ask and you will get it. We publish identifiers we can evidence — the company number and the procurement organisation number are on this site precisely because you can check them against Companies House and Find a Tender. Anything you need for your purchase ledger, including the VAT number, comes back the same working day.
- Can you quote in pounds?
- Yes. A quotation from Intepro UK Limited is a sterling quotation from a British company. Where a system is built in California the exchange exposure is ours to manage, not something passed to you mid-project.
Standards and conformity
- Do I need UKCA marking, or is CE still accepted?
- CE marking is accepted in Great Britain with no end date. The 2024 amending regulations made that permanent, and the 31 December 2027 date most people worry about governs where the UKCA mark may be placed, not whether CE is recognised. Northern Ireland is a separate market and takes CE. More on this.
- What does G99 Issue 2 actually require of my test bench?
- More specifically than most standards. Annex A.7.1.2.2 describes operating the module against a variable AC test supply, stepping voltage in increments of 0.5% or less, holding past the trip delay, then jumping in one step so trip time can be measured. The storage requirements came into force on 1 March 2026. More on this.
- Where is the G98 threshold?
- 16 A per phase. A product that sits just above it falls into G99 and a materially heavier type-test programme, which makes it a design decision rather than a paperwork one. More on this.
- Is IEEE 1547 relevant to me?
- Not for a British grid connection. IEEE 1547 with UL 1741 is the American interconnection regime; G98 and G99 are the British ones, and they are different tests with different settings. Equipment sold into both markets needs both.
Defence and security
- Can you meet DEFCON 658?
- DEFCON 658 flows down through the supply chain, which means a test system delivered into a defence programme is in scope, not only the prime. The controls land mostly on the test executive and the delivered software rather than on the power hardware. Tell us the risk profile the contract carries and we will tell you what it means for the system. More on this.
- Do you hold a CAGE code?
- Two different things get called the same thing. The group holds a US CAGE code, which belongs to the Californian facility and is a US federal registration — not something this entity can present as its own. The British counterpart is an NCAGE code, issued through the UK National Codification Bureau, and UK suppliers do hold them. Ask for ours and you will get the current position rather than an assumption. For UK public procurement the identifier that actually appears against us on a contract notice is our procurement organisation number, PRBY-9745-QRDP.
- Which Def Stans do you work to?
- Most often Def Stan 61-005 for vehicle and platform DC supplies, and Def Stan 59-411 for EMC. Both are cited on this site rather than quoted, because they sit behind the Defence Gateway. More on this.
Delivery and support
- Who supports the system once it is installed?
- Sandhurst is the entity you contract with and the first point of contact. Engineering sits at the group head office in California, where the systems are designed and built, and Limerick covers European service. On a delivered system that usually means the support conversation starts here and the engineering answer comes from the people who built it. More on this.
- Is calibration included?
- Ask, because it depends on the system and on what your assessor requires. We will tell you what a delivered system arrives with and what it needs annually, rather than describe an accreditation we do not hold ourselves.
- What happens when an instrument inside the rack goes end-of-life?
- This is the argument for open architecture and it is the main reason to buy an integrated system rather than assemble one. The test executive talks to instruments through interfaces rather than to specific model numbers, so a replacement supply is a configuration change and not a rewritten test programme. More on this.
Not the question you had
Tell us the standard you are assessed against and the device under test. That is enough for an engineer to give a real answer instead of a brochure.
