Trade and professional memberships

Yes

Annual subscription fees for trade and professional bodies are deductible as business expenses: Gas Safe registration, NICEIC or NAPIT electrical certification, FMB membership, and similar. Regulatory registration fees required to legally carry out your trade are also fully deductible. One-off joining or admission fees are generally not deductible under HMRC guidance. Only annual renewal fees qualify.

Common questions

Yes. Electrical certification body fees are deductible as annual professional subscriptions required for your trade.
I just joined the FMB. Can I claim the joining fee?
The one-off joining or admission fee is generally not deductible under HMRC guidance. The annual renewal fee in subsequent years is deductible.
