Bottom line:
What can be combined is test data; what cannot be combined is certificates and responsible entities. CE and UKCA technical standards for electrical and electronic products overlap heavily, and most test items under the three lines of LVD, EMC, and RED can share the same set of data. However, the certificates themselves cannot be mutually recognized: CE certificates are issued by EU notified bodies or under the manufacturer's self-declaration system, while UKCA certificates are issued by UK approved bodies, and the responsible entities and regulatory bases differ. In terms of reference ranges, combined testing can save approximately 20%–35% of testing costs compared with separate testing, and shorten the cycle by 5–10 working days.
Overlap and differences among the three product lines
Safety (LVD) — CE regulatory basis: Directive 2014/35/EU; Corresponding UKCA basis: Electrical Equipment (Safety) Regulations 2016; Test overlap: High; Items requiring supplementation: UK-specific clauses
Electromagnetic compatibility (EMC) — CE regulatory basis: Directive 2014/30/EU; Corresponding UKCA basis: EMC Regulations 2016; Test overlap: High; Items requiring supplementation: UK-specific clauses
Radio (RED) — CE regulatory basis: Directive 2014/53/EU; Corresponding UKCA basis: Radio Equipment Regulations 2017; Test overlap: Medium-high; Items requiring supplementation: UK requirements for frequency bands and power
The table above is based on publicly available regulatory comparisons; specific differing clauses are subject to the official original texts. High test overlap means that a single sample submission can cover most items under both sets of standards, but reports must be issued separately and certificates applied for separately.
Operating sequence for combined testing The first step is standards comparison. Engineers list the standard versions referenced by CE and UKCA respectively, marking version differences and UK-specific clauses. This step determines the feasibility of combination. The second step is a single sample submission. Samples need to cover all models to be tested, with the main model and variant models prepared separately. In terms of reference ranges, on the CE side, the LVD cycle is 5–10 working days at a cost of RMB 3,000–8,000, and the EMC cycle is 5–10 working days at a cost of RMB 3,500–9,000; on the UKCA side, supplementary items usually add 3–5 working days and increase costs by about 30%–50%. The third step is issuing certificates separately. Test reports are issued by partner laboratories; on the CE side, whether a notified body needs to be involved depends on the product risk level, and on the UKCA side, certificates are issued by UK approved bodies. The technical files for the two sets of certificates need to be archived separately and cannot replace each other.
Cost breakdown and common misconceptions What combined testing saves is mainly sample preparation, sample submission logistics, and some duplicate test items. What cannot be saved is the application fees for the two sets of certificates, technical file preparation fees, and annual maintenance costs. A common misconception is that a CE report can be directly exchanged for a UKCA certificate; in fact, UK approved bodies usually require reports to be issued by laboratories they recognize or assessed by them, and direct certificate exchange is not accepted. Another misconception is ignoring UK-specific clauses. Some products have additional labeling, instruction manual, or plug requirements under UK regulations; if these are not checked together during combined testing, subsequent rectification will add 3–7 working days. Testing is completed by partner laboratories with CNAS/CMA qualifications, and certificates are issued separately by EU notified bodies and UK approved bodies.

The takeaway:
What CE and UKCA combined testing saves is test data and sample costs; it cannot save certificates and responsible entities. Conducting standards comparison before sample submission is the key action for controlling total costs.
Our practice is to issue an applicability table first, so the testing scope is fixed before anything else is quoted.
