From our Christchurch base, we support individual premises and organisations with several sites. Our coverage directory explains the areas we serve; a location page describes our service area, rather than a separate branch.

UK employers and dutyholders must maintain electrical equipment so that it does not present danger. The Electricity at Work Regulations 1989 establish electrical safety duties, but they do not impose a universal requirement to PAT test every appliance annually. The appropriate inspection and testing programme depends on the equipment, how it is used and the risks of the environment.
The Health and Safety Executive’s PAT testing guidance explains how visual checks, inspections and testing can help manage these risks. Businesses should also consider any relevant insurer, contractual or sector-specific requirements.
AiO Pro PAT Testing can help businesses, schools, care homes and property managers arrange practical on-site testing with clear digital records. See our professional PAT testing services or request a quote.
Use our PAT testing calculator for a standard estimate, then tell us about anything that needs a tailored quotation. Our pricing page explains the minimum charge, item pricing and additional tests. Prices are shown excluding VAT.
London and sites inside the M25 need travel and access costs agreed in advance. Central London, large sites and specialist equipment require an individual quotation.
An itemised report helps you identify equipment, follow up failed items and plan future maintenance. Tell us about changes to your premises, new equipment or previous faults when arranging another visit.
See what you receive: reports and labels before you book.
Ask about experience with your equipment, the inspection and testing included, and how results and limitations will be recorded. Our PAT tester or electrician guide explains what matters when comparing providers.

** While performing testing our engineers will perform minor remedials to failed equipment if possible to ensure any disruptions to the business are minimised. Any minor appliance rewires and replacement of damaged plugs will be rectified and applied to the invoice. Any more extensive repairable issues will be reported to the responsible persons of the business and repair price agreed before a repair takes place. If an appliance is unrepairable on site it will be taken out of service.
