Same day solution for Ring Main fault
Customer Service
I called about my downstairs ring main tripping even when nothing was plugged in. Graham offered to call in on his way home from another job to do an initial inspection. He called me to confirm his arrival time and on arrival checked the circuit breaker. He then decided to proceed to complete the fault finding process. One located he fixed the fault and tested everything before leaving. Friendly efficient service providing good quality work. Really pleased and would use again.

Professional, trustworthy and reliable
Customer Service
Work carried out - New fuse board, repair oven and install isolated switches for oven and hob. I liked Graham immediately. He is very personable. He took me through my various options, explaining everything clearly to me. He arrived on site exactly when he said he would and the work was completed in a day. Everything was left neat and tidy with all rubbish cleared away. The cost of the work was as quoted and I was very happy with the cost. I find getting traders in somewhat nerve-wracking and you are never sure what sort of service you will get but I cannot recommend this company highly enough. I will definitely use them again.

Trustworthy and reliable
Customer Service
When you know that you are in a safe pair of hands when come to electrical issues, that makes a staggering difference to your quality of life in the immediate future. We were inundated with dozens of dangerous and urgent findings from a recent electrical survey carried out by a different electrician. Needless to say this created lots of stress and panic. What followed from the survey was an astronomical figures of price quoted to rectify those issues. Graham and Dave were called in as a second opinion. They are friendly, respectful, highly competent and reliable. They provided a much more pragmatic assessment and holistic solutions to our electrical problems. Their work is of high quality and kept the workplace neat and tidy. They completed their work ahead of schedule and under budget ( Yes, under budget !). You don't always get these things in this day and age. A highly commendable team and company. I will definitely become a repeat customer in the future.

EICR plus electrical works - excellent work
Customer Service
Graham at Spectrum was prompt, efficient, kept to specified times and was professional throughout, as was his colleague. I have already recommended them to others. All works were pointed out to me and advise given which was much appreciated.

Installing a time switch for the bathroom towel rail
Customer Service
This was a slightly unusual request which was fulfilled with only a minor hiccup when the installer found the switch he intended to supply was faulty. This was rectified quickly and the job finished in a tidy fashion.

Highly professional, flexible and friendly service
Customer Service
I required several small jobs to be completed at my home which equated to a morning's work. Graham and his team provided an itemised quotation following a short assessment of the works to be done which was reasonably priced. On agreement to proceed, Graham scheduled the works around my home-working commitments which was hugely helpful. The work performed was to a very high standard with helpful advice offered along the way. They even managed to find time to add an additional plug point which was not in scope of the original work. I would highly recommend this company and will be using Spectrum Electrical Services again.

Reliable, friendly, quality service
Customer Service
As a single lady, I worry about being fobbed off and overcharged. From the outset, my queries about the work I needed completing were met with professional courtesy and replies sent in a timely manner. I was up against a tight deadline but this was not an issue. On the day the inspection work was thorough and attention to detail impressive. Necessary remedial work was fully explained and completed immediately at a very reasonable cost. I have no hesitation in recommending Graham and his team and will be relying on them for all my electrical work in the future.

Good workmanship and reliable
Customer Service
Graham was communicative and trustworthy. He and his team did a great job and gave us peace of mind that the consumer board and the house electrics were all sound. Thorough, tidy, workmanship. Came up with a good solution to a challenge we had with a kitchen under-unit and island lights. I would highly recommend.

Basement lights reviewed and new switches installed to resolve loading problem. Old fixtures in child's room removed and made safe. outdoor lights - one repaired and one replaced. Great service. Solved all of our issues and a quality finish on everything.
