Verified Premium · Methodology

Reviews are gameable.
Verification isn’t.

Eight independent checks. Every Verified Premium builder passes them all. Annual re-verification keeps it honest. Every status change is publicly auditable.

01

The thesis

Trust mechanics in our category fall into two camps: pay-to-list directories that filter by money, and review marketplaces that filter by who's loudest. Both are gameable. Verification is the third option — checks against external sources of truth that builders can't manipulate.

What this is

A repeatable, evidenced, time-stamped accreditation that links to external authorities — Companies House, the insurer, the trade body, HMRC. Each check resolves to a status backed by a document or call.

What this isn’t

A subjective rating. We don’t score builders out of five stars. We don’t accept self-attestation. We don’t charge to skip checks. Verification is binary: pass or don’t.

02

Eight stages

Every Verified Premium builder passes all eight. Failure on any one stage prevents accreditation.

  1. 01

    Companies House

    We confirm the company exists, is active, isn't subject to a recent dissolution or strike-off, and that no director carries a current disqualification.

    Evidence
    Companies House public record · auto-checked daily for the active set
    Re-checked
    Annually + on every status change
  2. 02

    Public liability insurance

    Minimum £2m cover. We verify the certificate directly with the insurer rather than accepting the document at face value. Expiry date tracked; suspension auto-fires on lapse.

    Evidence
    Direct verification with the insurer · expiry-tracked
    Re-checked
    On expiry · grace window 14 days
  3. 03

    Trade body membership

    Where the builder claims membership of FMB, NHBC, TrustMark, Gas Safe, NICEIC or FENSA, we cross-reference against the body's published member list. Claims that don't reconcile are rejected.

    Evidence
    Member-list cross-check · Firecrawl-watched where APIs unavailable
    Re-checked
    Quarterly
  4. 04

    VAT registration

    VAT-registered status confirmed with HMRC. Builders below the threshold may declare exemption, recorded with the declaration version.

    Evidence
    HMRC VAT lookup · declaration document for exempted
    Re-checked
    Annually
  5. 05

    Photo-verified portfolio

    Minimum five completed projects, with photographs and a short summary of each. New applicants receive a site visit from the verification team to confirm the work was done by them.

    Evidence
    Photographs + summaries · site visit for new applicants
    Re-checked
    Annually with new evidence
  6. 06

    Two written references

    Two prior customers contacted directly by our verification team. Each reference call follows the same script and is captured as an audio note. Two passes from two distinct customers required.

    Evidence
    Script-led calls · audio notes retained
    Re-checked
    Re-collected at annual re-verification
  7. 07

    DBS check (principal)

    Where work is in occupied homes, the principal completes a DBS check via our certificated provider. The result is captured against the verification record, never published.

    Evidence
    Disclosure & Barring Service · certificated provider
    Re-checked
    Five-yearly + on principal change
  8. 08

    Annual re-verification

    Every check repeats annually. Documents nearing expiry trigger reminders at 30, 7 and 0 days. Stale documents trigger automatic suspension; suspension lifts when the document is refreshed.

    Evidence
    Cron-driven scheduler · automatic suspension on lapse
    Re-checked
    Always

03

Annual re-verification

Accreditation isn’t a one-off. Every check repeats every year, and document expiry is tracked continuously between cycles.

30 days out

First reminder

Email to the builder principal flagging the upcoming re-verification window. Documents that expire in the same window are listed.

7 days out

Second reminder

Email + dashboard banner. The verification team is alerted to begin gathering re-checked evidence.

0 days

Suspension

Status flips to suspended. Builder no longer receives auction invites. Suspension lifts immediately on refreshed evidence; otherwise archived after 14 days.

04

Public verification page

Every Verified Premium builder gets a public profile at /verify/CB-XXXXX. Indexable by search engines, no consumer data, status backed by the audit trail.

What lives there

  • Status banner — Active, Suspended, or Not recognised.
  • Identity — registered name, trading name, Companies House number.
  • Trades and service areas covered.
  • Insurance provider, cover, expiry.
  • Trade-body memberships.
  • Eight-stage accreditation checklist with verified-on dates.
  • Verification history — every status change, time-stamped.
  • Report-an-issue route.

What disqualifies

Honest list. These are the patterns we will not accredit, and the patterns that get a Verified Premium builder suspended.

  • Director disqualifications, recent dissolutions, or strike-off proceedings.
  • Public liability cover below £2m, or cover that has been allowed to lapse without renewal.
  • Claimed trade-body memberships that don't reconcile with the published member list.
  • Patterns of complaints across more than one homeowner that resolve against the builder.
  • Failed reference calls — two passes from two distinct customers required.
  • Failure to provide DBS evidence for occupied-home work.
  • Repeated failure to respond to invited auctions, leading to a sustained low response score.
  • Misrepresentation on the application — even if discovered after approval.
