How We Verify Converters
The UK conversion market is largely unregulated — anyone can call themselves a converter. This page explains what we check, what the Verified and Accredited badges mean, and how the Trust Score is calculated. No business can pay to change its Trust Score or to mark a check we have not completed.
What we check
Companies House registrationre-checked monthly
We match each business to its Companies House record and check its status and incorporation date. Dissolved or liquidated companies are flagged for review.
Public liability insurance
We record whether a converter declares public liability cover and, where provided, the level of cover. Shown on the profile when verified.
Gas Safe registration
Any converter fitting gas systems should hold Gas Safe registration with the LPG modules. Where a registration number is verified it appears on the profile with a link to the official register.
Industry accreditations
NCC approval, VCA type approval and similar industry schemes, checked against the relevant scheme where records are public.
Trading history and address
Business address, trading name consistency, and years in business.
Website and portfolio reviewre-checked monthly
We check the business website is live (re-checked automatically) and review the portfolio for genuine, recent work.
The three vetting tiers
Listed
In the directory with whatever checks we have on file. No Verified or Accredited badge. Unclaimed and Free listings stay here.
Verified
Claimed listing on Pro, including the 30-day trial. Companies House registration and insurance declarations checked, and contact details confirmed with the owner. Shown as a gold badge.
Accredited
Claimed listing on Premium, including the 30-day trial. Everything in Verified, plus industry accreditations (NCC, Gas Safe and similar), a portfolio review, and ongoing checks. Shown as a green badge.
A Verified or Accredited badge appears next to the name only when the listing is claimed and on the matching plan. The verification panel lists each check on its own — including the ones we have not confirmed yet. We never show a tick for something we have not checked.
How the Trust Score works
Every converter gets a Trust Score out of 100, computed automatically from seven weighted factors. The weights are published here in full:
| Factor | Weight |
|---|---|
| Customer reviews (rating and volume) | 30% |
| Vetting tier | 20% |
| Profile completeness | 15% |
| Responsiveness to enquiries | 10% |
| Years in business | 10% |
| Accreditations held | 10% |
| Portfolio size | 5% |
The vetting-tier weight is a score input. It is not the public Verified or Accredited badge, and paying for a plan does not change the score. Scores update as reviews arrive, profiles are completed, and checks run. The same score drives our best conversion companies ranking — it is not editorial opinion.
What verification is not
Verification confirms a business is legitimate and accredited as claimed — it is not a guarantee of workmanship, price, or delivery. Before commissioning a build: view completed conversions in person, speak to recent customers, confirm gas and electrical sign-off arrangements, and get everything in writing. If information on a profile looks wrong, use the “report” link on that profile and we'll re-check it.
Frequently asked questions
Can converters pay for a higher Trust Score or ranking?
No. The Trust Score is computed from the weighted factors published on this page and no business can pay to change it. Pro and Premium unlock the Verified and Accredited badges plus profile features such as photos, analytics and featuring. Those badges are separate from the score.
How often is verification repeated?
Companies House status and website liveness are re-checked automatically every month, and each profile shows a "last verified" date. Accreditation and insurance details are re-checked when a profile is claimed or updated, and whenever an issue is reported.
Does verification guarantee the quality of a conversion?
No — verification confirms a business is legitimate, insured and accredited as claimed. It is not an endorsement or a guarantee of workmanship. Always view previous builds, speak to recent customers, and get a written contract before paying a deposit.

Each profile shows the checks on this page individually. A missing check is marked not verified — it is not implied to have passed.
