Gary has totally wired our new house. We can't praise him or recommend him highly enough! He is very professional, hard working, great at getting back to us via message or phone calls, he arrives when he says he will and he is fantastic at his job.

The old switch box was removed and replaced with a new one which was also relocated to enable easier access with all excess wiring being removed. 100% happy with the completed work and would definitely recommend.

First class experience from initial assessment to completion of the work. Excellent advice on the most suitable choice of electrical storage heaters for my needs. Gary is excellent to deal with, very reliable and responsive. Competitively priced. I would highly recommend. Delighted with the work and entire level of service.

We booked Garry to carry out an EICR before going ahead with installation of a home charger for our EV by the car retailer’s subsidiary.
We were so impressed with his thoroughness and professionalism that we got Garry to fit a charger himself (Zappi 2.0). He and his apprentice arrived on time, lifted carpet, cut access hatch, connected cabling to meter with RCD, drilled walls, fitted charger, replaced carpet, vacuumed, explained operation of charger - all in less than 3 hours - and charged the same or less than other company (even with “discount”).
This young man deserves to succeed and we have no hesitation in recommending him.
Thank you Garry (and Braden).

Garry was completely professional from the initial contact to completion of a full house rewire. He was clear, transparent and offered positive advice on all aspects of the job. His outline of work involved and timescales were adhered to from the first minute.
A rewire can be a messy process so we opted to let the team work whilst we opted to vacate for a few days. We returned to all work completed to our satisfaction and all areas made good where there was any disruption. A truly five star review, well earned. We have no hesitation in using again or in recommending Garry and his team to others.

Garry was easy to contact, he arrived when he said he would, he had anticipated all the parts he would need and brought them with him, he carried out the required work efficiently and quickly, and cleared up leaving no mess. His reasonable invoice arrived in good time. Very satisfied.

Professional reliable and Ivenow had a few of the workers and each and everyone of them are just great.

Always willing to take the time to explain the job from start to finish along with explaining the workings once jobs are completed.

Always arrive on time when it's said and leave their working area clean and tidy too.

Personally I'd highly recommend this business.

Garry assessed prior work and claims of work which were paid for. His report identified thousands of pounds of work not completed. His reports will assist in pursing complaints.

Garry has now completed all works to building control pass standard and adapted to changing plans. This has included connecting electric cables and cutting out through 3 ft walls into an unused space and connecting kitchen appliances. Working with Corecut to have the extractor fan cored out. And he and his team have been adapting lighting to be dimmable. Other works include fitting lighting outside and there are other plans I being discussed.

Garry has always maintained professional boundaries as have his staff. I happily recommend his business.

We have a few rental properties and Garry’s company has always dealt with any electrical issues and/or required safety certification for us.

We’ve always found Garry and his staff to be very professional, friendly and trustworthy as well as being very reasonable with their prices, highly recommended.

Review Comments
We recently moved into a lovely old house (built c. 1888) and knew that there would be some investigative and general maintenance work required. We knew that the first two things we'd have to address would be the roof and the electrical condition. Tracking down a reliable and competent tradesperson was always our main concern, particularly as we were unfamiliar with the area.

The trusted trader site has been our go-to resource for added peace of mind. We contacted Garry Johnston and he was quick to respond, arranging a home visit to assess the work required. He came up with a recommended programme of works, dealing firstly with the relocation of electrical sockets from skirtings at floor level (common in older homes) to 300mm above FFL as per our initial request.

Garry followed this up with a thorough assessment (EICR - electrical installation condition report) conducted with a colleague. He issued the report in a timeous manner and the quality / level of detail was impressive. It identified that parts of the house were wired to current standard, but the lighting circuits were all unearthed VIR wiring.

We arranged for his team to attend for a full rewire. Yet again, he was able to schedule the works for a suitable time. The team arrived promptly on the date promised, and worked tirelessly for four full days, stopping only for lunch and to collect additional materials.

The anticipated physical intrusion to walls, floors, and ceilings was kept to a minimum, with all necessary work patched up to a high standard of finish. All sockets and switches were replaced with new back boxes and face plates.

The cost of the works was reasonable, and reflected the competency of the team, quality and completeness of the works.

We'll have Garry Johnston and his business back to the house next year for more work installing outdoor circuits and our garage building.

Highly recommend!
