An outage history helps describe the problem but does not determine the answer alone. Identify what must remain supplied, what can stop and how long the interruption can be tolerated.
What the work can include
The work can include reviewing load requirements, assessing existing equipment, developing a connection and changeover scope, coordinating generator installation or replacement, and arranging maintenance and functional testing. Temporary provision needs its own connection, siting and removal plan.
The deliverables identify supported circuits, operating assumptions, the changeover arrangement and relevant inspection or test records. Fuel, exhaust, ventilation, access and controls are considered alongside electrical work. Where civil works, enclosures or associated services are needed, they form named parts of the package.
Important decisions
Selected loads or the whole property. Backing up selected circuits can be a different design from supporting every connected load. The assessment considers starting demand and the order in which equipment returns, not simply a total taken from equipment labels.
Generator or UPS. A generator-based arrangement has a starting and transfer sequence. Equipment that cannot tolerate that interruption may need a coordinated uninterruptible power supply. Compatibility must be assessed; Eaton explains generator and UPS interactions.
Manual or automatic operation. The choice affects controls, monitoring, the people needed on site and the test plan. These decisions must be explicit before equipment is selected.
Assessment and preparation
Tell us which property services or pieces of equipment you want to keep supplied, and what interruption you can accept. Send existing electrical records and generator details where available. An owner may need input from the occupier to establish actual equipment use and restart requirements.
Identify a possible equipment location, delivery access and the person responsible for fuel and operation. Exhaust, noise and maintenance space need assessment before siting is agreed. HSE explains generator hazards in its electrical safety guidance.
How the work proceeds
We turn the property's required outcome into a list of supported loads, assess the existing connection and identify the electrical and associated work. Where rented or shared areas are involved, we establish who can approve changes and where another party's permission is needed.
The work is arranged around access and the interruption to occupied areas. At handover, the owner receives the relevant test results, supported-circuit information, operating responsibilities and follow-up tasks. Controls and maintenance instructions need to be understood by the person who will manage the equipment after installation.
Cost, timing and disruption
The price depends on supported loads, generator location, connection distance, fuel arrangements and any enclosure, foundation or exhaust work. A property with limited outside space may need a different practical solution from one with an accessible service area.
Allow time for the assessment, equipment supply, permissions and a suitable testing window. Agree who will be present for access and handover, and which equipment or occupied areas will lose power during connection. Removal or reinstatement after temporary use should be included in the original brief.
Sector applications
For hospitality premises, refrigeration, business systems and customer areas have different needs. For managing agents, establish which shared services and parties are included. A property-level brief should identify the actual circuits needing support rather than describe every service as critical.
These applications sit within the full sector range, including FM companies, public and community premises, leisure, construction, veterinary premises, energy and utilities, social housing, laboratories and secure estates. The complete service and project offering is available across the sectors we serve; the technical brief follows the particular site.
Local coverage
Our North East coverage includes Northumberland, Tyne and Wear, County Durham and the Tees Valley: Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees and Middlesbrough, together with the areas in the full locations directory.
For an individual property, include the full address, access contact and any restriction affecting delivery or working hours.
Frequently asked questions
Will a generator keep equipment running without interruption?
Not by itself in every arrangement. Starting and changeover take time. Identify equipment that cannot tolerate interruption so an appropriate combined solution can be assessed.
Can we connect a generator to the existing building supply?
Only through a correctly assessed and designed arrangement. Supply separation, protection and operating interfaces need technical review; a generator is not connected by improvising a feed into a socket.
Is a successful engine start enough to prove the system?
No. The required tests should address the supported loads and changeover sequence. An engine can start while a separate distribution or control issue prevents useful backup.
Can I arrange backup power for a rented property?
Start with the landlord's permission and the equipment you need to support. Establish who owns the proposed connection and generator location, and who will operate and maintain the arrangement.
Knowledge and useful reading
Read what fixed-wire testing covers for the installation assessment and how maintenance frequencies are determined for ongoing care. These explain supporting tasks; the backup operating sequence also needs a system-specific test plan.
