Services

From a new fuse board to a full containment and data installation.

Consumer units

Is your fuse board due an upgrade?

A safer home starts with modern electrical protection. Upgrading an old fuse box is one of the most worthwhile safety improvements you can make, giving your family an important line of defence against electrical faults.

Signs it may be time

  • Rewireable fuses (wire in a ceramic holder) instead of switches
  • No RCD protection on your circuits
  • A plastic consumer unit, or a board with signs of heat or scorching
  • Frequent tripping, or adding new circuits for an extension or kitchen
  • An electrical report (EICR) that recommends replacement

Anthony PlantDomestic · Google review

We required ODO Building Services for a commercial installation. We needed a fuse board upgrade and required some armoured cabling installed for are workshop. Very impressed with the installation and the professional and speed of the installation.

Jack BakerCommercial · Google review

Really impressed with the electrical work carried out — professional from start to finish. Turned up on time, explained everything clearly, and the standard of work was excellent. Tidy, efficient, and clearly knows the trade inside out. Fair pricing too, no hidden surprises. Wouldn't hesitate to recommend or use again for future work.

FAQ

Common questions.

Do you provide free quotes?

Yes. Quotes are free and without obligation. For most jobs we’ll visit, look at the work and give you a clear written price before anything starts.

Can you upgrade my consumer unit (fuse board)?

Yes, it’s one of our main services. We replace old fuse boxes with a modern consumer unit with RCD/RCBO protection, test every circuit and give you the certificate. Consumer unit replacement is notifiable work, so it is registered with Building Control.

Do you take on commercial work?

Yes: distribution boards, SWA and power cabling, lighting, cable containment and data cabling. On larger projects we bring in additional qualified labour as the job requires.

Are you qualified and insured?

Yes. Work is carried out by an ECS Gold Card electrician qualified to NVQ Level 3, AM2 and the 18th Edition (BS 7671), and ODO Building Services holds public liability insurance.

What areas do you cover?

We’re based in South London and work across Greater London and surrounding areas. Commercial projects further afield are considered case by case. See areas covered.
