5 Best PAT Testing Companies London (Prices & Reviews)
Whether you manage a single office or a portfolio of rental properties, finding reliable PAT testing companies London businesses and landlords actually trust can be harder than it should be. Prices vary wildly, turnaround times differ, and not every provider issues the compliance documentation you need to satisfy insurers or meet health and safety obligations.
We put this guide together because, as an electrical testing company ourselves, we know what separates a solid PAT testing service from a rushed one. At Electrical Testing London, our engineers carry out PAT testing across the capital every week, so we understand exactly what clients should expect in terms of pricing, certification, and professionalism. That first-hand experience informed every recommendation on this list.
Below, you'll find five of the best PAT testing companies operating in London right now, with real pricing details and reviews to help you compare. We've included ourselves where relevant, but this isn't a sales pitch, it's a practical breakdown designed to help you book the right provider for your situation, whether that's a one-off test or an ongoing contract.
1. Electrical Testing London
Electrical Testing London sits at the top of this list partly because we wrote it, but mainly because we back it up. Our engineers carry out PAT testing across London every week, each one holding a minimum of 10 years' experience and a thorough understanding of what landlords and commercial clients actually need from a compliance service.
Quick verdict
Among the pat testing companies London property managers and businesses can choose from, Electrical Testing London stands out for combining qualified engineers with same-day documentation and a broad range of compliance services under one roof.
Best for
Landlords, commercial property managers, and businesses in London and the South East who want PAT testing handled by a team that also understands the wider electrical compliance picture, rather than a company focused solely on PAT.

PAT testing sits alongside a full suite of services including EICRs, emergency lighting testing, consumer unit replacement, EV charger installation, and remedial electrical works. You can consolidate multiple compliance requirements with a single contractor, which reduces coordination time and keeps your documentation consistent.

Every tested appliance gets a pass or fail label applied on-site. You also receive a formal compliance certificate that satisfies insurer requirements and meets health and safety obligations under UK law.

Next steps
All five pat testing companies London businesses and landlords find on this list are capable of delivering compliant PAT testing, but the right choice depends on your specific situation. If you manage a single small office, a specialist provider focused on volume and speed may suit you fine. If you handle multiple properties or need several compliance services under one contractor, a company like Electrical Testing London gives you more flexibility without adding extra coordination overhead.
Before you book anyone, confirm that the engineer holds a recognised PAT testing qualification, that certificates are issued on the day, and that the quote covers all appliance classes relevant to your site. Those three checks alone will filter out most providers who cut corners.
