Sourcing electric boilers from China
Electric central heating boilers and their parts from China carry UK duty ranging from 0% to 2%: complete boilers pay 2% and parts 0%. Before selling in Great Britain, check electrical conformity, applicable ecodesign requirements and energy labelling for the exact model. Cambridge China Bridge sources electric central heating boilers.
2% on complete boilers, 0% on boiler parts
Heading 8403 covers central heating boilers other than those of heading 8402. This guide focuses on electric boilers that heat water for a central heating circuit. Confirm the function and construction rather than classifying from the supplier's product name. See the wider central heating boiler guide.
Read from the UK Trade Tariff on 1 October 2026, complete boilers of cast iron or other materials carried 2% duty on goods from China; boiler parts carried 0%. The supplied tariff record lists no anti-dumping or countervailing duties, suspensions or attached import controls for these lines.
Confirm the commodity code using the heating circuit, materials and whether the shipment contains complete boilers or separately supplied parts. Do not assume that every replacement electrical component belongs under the boiler-parts code.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Cast-iron central heating boilers | 8403 10 10 00 | 2% | None |
| Other central heating boilers, including electric models | 8403 10 90 00 | 2% | None |
| Cast-iron central heating boiler parts | 8403 90 10 00 | 0% | None |
| Other central heating boiler parts | 8403 90 90 00 | 0% | None |
Electrical supply, heating circuit and model evidence
Specify the electrical supply and phase arrangement, rated input, heating stages, water temperature range, operating pressure, connection positions and mounting method. State whether the pump, expansion vessel, pressure relief valve and external thermostat interface are included. Agree the heating-element material, water-treatment instructions and access for replacing elements and control boards.
For Great Britain, electrical equipment needs the relevant conformity assessment, technical documentation, declaration of conformity and conformity marking. Importers must ensure that instructions are in easily understandable English. Match the declaration and supporting test reports to the finished boiler, including its controller and supplied accessories.
Confirm with the relevant authority the applicable ecodesign and energy labelling requirements for the exact electric boiler model and its rated output. Obtain the applicable efficiency evidence and energy-label documents for the exact electric model. A claim about conversion of electricity into heat does not replace model-specific compliance evidence.
Worked duty example
Illustrative example, not a quote: Illustrative shipment of 40 electric central heating boilers under 8403 10 90 00, invoiced at £28,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £32,000. Duty at 2% is £640. Import VAT at 20% is charged on the customs value plus duty, £32,640, so it is £6,528. Import taxes total £7,168; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £640 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Electrical assembly: compare terminal layout, cable entries, earthing connections and heating elements with the approved sample; have electrical safety results recorded against the agreed test plan.
Water circuit: inspect joints and seals, run the agreed leak and pressure tests, and check pump operation, air venting and pressure relief arrangements.
Controls: run heating demand, thermostat response and staged heating; test overtemperature and loss-of-flow protection against the agreed design.
Documents and arrival condition: match model identifiers, conformity documents, energy-label information and English manuals; inspect casing damage, mounting brackets and water connections after unpacking. Use a product-specific inspection brief.

What goes wrong
A boiler can match the catalogue photograph while having a different electrical supply, controller or hydraulic assembly. Treat loose terminals, leaking joints, unreliable temperature sensing and protection that fails to stop heating as inspection risks. Compare the shipment with the approved sample and retain the test records.
Replacement elements or control boards can also differ between production batches. Agree component identification, replacement access and spare-part compatibility before ordering. Ask for testing and certification support when the supplier's documents do not clearly cover the supplied configuration.

Frequently asked questions
What is the UK import duty on electric central heating boilers from China?
The supplied tariff record shows 2% on complete boilers and 0% on boiler parts, with no anti-dumping or countervailing duty, suspension or attached import control.
Can an electric boiler use CE marking in Great Britain?
Yes. Electrical equipment can use CE or UKCA marking under the applicable conformity route. Check the declaration, technical documents and finished model rather than accepting the mark alone.
Do electric central heating boilers need an energy label?
Confirm with the relevant authority whether the exact space-heating boiler model needs an energy label. Obtain the applicable label and supporting efficiency evidence for the exact model.
What should I specify before asking a Chinese factory for a quote?
Specify electrical supply, heating output, water temperature and pressure, included hydraulic components, thermostat interface, mounting, safety protections and replacement-part compatibility.
