What does NASC cover?
NASC accreditation typically covers technical competence, ongoing CPD requirements, insurance cover (typically £2M+ public liability) and a published code of conduct. Each NASC member is required to renew or be reassessed periodically — the exact cadence depends on the membership tier. The body operates a complaints route for homeowners: if a registered member fails to honour their commitments, NASC can investigate, mediate, and in serious cases revoke membership.
Verifying a NASC-registered tradesperson
- NASC membership number — verify on the public register before signing any quote
- Current insurance certificate (£2M+ public liability typical) — NASC requires this for active members
- Written quote with payment milestones — NASC members commit to written contracts, not verbal agreements

NASC FAQ
What does NASC accreditation actually require?
Technical competence (typically a recognised qualification), evidence of trading history, current insurance, adherence to NASC's published code of conduct and a documented complaints procedure. Some tiers require independent audit; all require periodic reassessment.
How do I check if a tradesperson is NASC-registered?
Visit https://nasc.org.uk/ and use the public register search. Always check before signing a contract — registrations occasionally lapse, and the public register is the authoritative source.
Is NASC membership legally required?
For most trades, no — UK trade accreditation is voluntary. The big exceptions are Gas Safe (legally required for gas work) and some renewable-energy schemes (MCS required for grant claims). For other trades, NASC membership is a strong quality signal but not a legal mandate.
What if I have a problem with an NASC member?
Raise it directly with the trader first, in writing. If unresolved, escalate to NASC via their complaints procedure. NASC can investigate, mediate and ultimately remove members who fail to meet the code. On TradeMatch, escrow-protected payments mean disputes are mediated before any release of funds — a faster route in practice.
Why NASC verification matters before any deposit
Lapsed accreditations are the most common silent failure on UK trade hires — registrations expire annually and not every trader updates their listing. Always verify the NASC number on the public register on the day you sign, not at first meeting. On TradeMatch, every NASC-registered tradesperson is independently re-checked before they can quote on your job, and the registration link is shown on their profile so you can confirm yourself.
