  • Upgrade fusebox and do a complete electric safety check

    Hired Benchmark to install a new fusebox, complete safety checks, and do other electric work for a property I recently purchased before moving in. Tom and his colleagues were very responsive and reliable throughout the process. The work was completed on time and to a very high standard at a good price. I would definitely hire Benchmark again in the future and highly recommend them.

  • 4 power sockets need adding/moving on partition walls

    Great comms and fair quoted price

  • Heating system needs wiring

    Big thanks to benchmark electrical for the fantastic job they did for me in Oxford, wiring up a massive 6 zone heating system. The wiring was very neat and tidy and everything was labelled up so it’s easy for my client to see what valves operate which circuits.
    Brilliant thanks again guys!
