Why Our E-Liquid Is Manufactured in Wales
Celtic Vapours has manufactured e-liquid in Swansea since 2011. This page explains why Welsh manufacturing matters for quality, traceability and what it means for every bottle you buy.
Quick answer: Celtic Vapours manufactures in Swansea, Wales because it gives the brand complete control over ingredient quality, production standards and batch traceability without relying on external contract manufacturers. Manufacturing in Wales under UK TRPR regulations ensures that every product meets the MHRA's requirements for ingredient purity, emissions testing and labelling before going on sale. It also means shorter supply chains, faster response to quality concerns and the ability to maintain consistent flavour profiles across every production run.
The Case for In-House Welsh Manufacturing
When Celtic Vapours was established in Swansea in 2011, a significant proportion of e-liquid sold in the UK was either imported from overseas or produced by contract manufacturers with limited traceability. The decision to manufacture in-house in Wales from the outset was driven by a desire to control quality at every stage of production rather than accepting whatever a third-party blender delivered.
In the years since, UK TRPR regulations have formalised many of the standards that Celtic Vapours adopted voluntarily from the beginning. MHRA registration, pharmaceutical-grade ingredients, clean room production, emissions testing and full batch traceability are now legal requirements for all UK e-liquid manufacturers. For Celtic Vapours, these requirements aligned with practices already in place rather than requiring a fundamental change in approach.
Five Reasons Welsh Manufacturing Makes a Difference
Full Ingredient Traceability
Manufacturing in-house in Wales means Celtic Vapours knows exactly where every ingredient in every bottle comes from. PG, VG, nicotine and flavour concentrates are sourced from certified UK and European suppliers. Full batch records are maintained from raw material delivery through mixing, quality testing and bottling. This traceability is a legal requirement under TRPR and also gives Celtic Vapours the ability to identify and investigate any quality concern quickly without involving an external manufacturer.
Consistent Flavour Across Batches
When a brand manufactures in-house, the same team, the same equipment and the same processes are used for every production run. There is no variation introduced by switching contract manufacturers or by a third-party blender changing its ingredient suppliers. Vapers who find a Celtic Vapours flavour they enjoy can reorder with confidence that the next bottle will taste the same as the last. This consistency is one of the most valued attributes in an e-liquid brand and it requires direct control of the manufacturing process.
UK Regulatory Compliance from the Start
Every product manufactured by Celtic Vapours for UK sale is registered with the MHRA under the TRPR notification system. This registration requires submission of full ingredient details, emissions testing data and production information for each individual flavour and nicotine strength variant. Manufacturing in Wales under UK law means Celtic Vapours operates under the same regulatory framework as its customers expect, with no ambiguity about which country's rules apply and no dependence on overseas manufacturers interpreting UK regulations correctly.
Shorter Supply Chain
Producing in Swansea rather than importing finished product from overseas manufacturers means the supply chain from production to customer is considerably shorter. This reduces the transit time during which products are exposed to temperature variation and other storage risks. It also allows Celtic Vapours to respond more quickly to demand changes without holding large quantities of stock that has been in transit for weeks. Shorter supply chains also mean a lower environmental footprint compared to importing finished e-liquid from international manufacturers.
UK Manufacturing vs Overseas E-Liquid
Not all e-liquid sold in UK vape shops is manufactured in the UK. A significant proportion of the market is imported, particularly from manufacturers in China and other Asian markets where production costs are lower. The e-liquid may be sold under UK brand names and carry UK-compliant labelling. The underlying production and ingredient sourcing standards may differ from those applied in a UK or European facility.
Under UK TRPR, all e-liquids sold in the UK must be registered with the MHRA regardless of where they are manufactured. However, the quality of that registration depends on the accuracy of the information submitted by the manufacturer. A UK-based manufacturer producing under MHRA oversight is subject to the same regulatory environment as the finished product. An overseas manufacturer submitting MHRA registration documentation is operating under a different regulatory system domestically and the MHRA has less direct oversight of their day-to-day production.
For vapers who prioritise ingredient traceability and manufacturer accountability, choosing a brand that manufactures in the UK specifically and has been doing so consistently since before TRPR regulations were introduced, provides a meaningful additional level of confidence in the product.
| Factor | UK In-House Manufacturing | Overseas Contract Manufacturing |
|---|---|---|
| Ingredient traceability | Full traceability to certified UK and EU suppliers | Depends on overseas supplier transparency |
| Production standards | UK clean room and TRPR requirements enforced directly | Compliance depends on overseas facility standards |
| MHRA registration | In-house submission with direct knowledge of production | Submission accuracy depends on overseas manufacturer |
| Batch consistency | Same team and equipment for every run | Consistency depends on contract manufacturer controls |
| Supply chain length | Short, domestic | Long, international with transit risk |
| Response to quality concerns | Direct and fast | Slower due to distance and third-party involvement |
