How this list works
How we built it, and what we have not checked
- How we found the firms. Web searches, trade listings and firms’ own websites, from early October to 14 Oct 2026. We aim to list every firm that says it does this job, not a sample.
- What the labels mean. Confirmed comes from an official record such as Companies House. Stated is what the firm says on its own website. Not found means we looked and could not find it.
- What we have not checked. On 14 Oct 2026 we checked that each firm’s website loads and mentions this job, and checked any company number it publishes at Companies House; firms that failed are left out. Everything else is as each firm states it. We have not yet read every firm’s website in full, or confirmed anything with the firm.
- Order. A to Z. There are no scores, ratings or paid places.
- How we make money. Nobody pays to be listed or for where they appear. If firms ever pay us, it will be for enquiries, never for a place on the list.
- Something wrong? Firms can ask us to correct their facts through our contact page.
