At SPEC we aim to excel.
Below are some comments from our clients.

Please pass on my grateful thanks to the team that attended site in September 2017. This was a big ask, to inspect and service nine transformers, HV switchgear and main LV switches in a four and a half hour window, and although I had reassured my senior team that this would be completed on time, I was worried about the scale of the task. My previous experiences with SPEC Ltd were some comfort in that I had only enjoyed good service. In the event, the teams all turned on time, quickly deployed to their respective locations and the task was carried out with military precision. The power went off at 08:00 as planned and was reinstated at 12:30, with all tasks completed and tested.

Thanks again for a challenging job well done.

Mr Laidler | Project Manager

I want to once again thank SPEC for their efforts last week which were superb. Everything went to plan and there were no hiccups at all.

Firstly – the response to the problem on Sunday the 8th in getting us an emergency generator to site and running within 4 hours, was a stretch but your team did a great job in stifling temperatures.

Secondly – Dave pulled out all the stops (once again) to organise labour for various efforts including the air box replacement on Thursday, making the final push on Saturday a relaxed affair in comparison.

Thirdly – you used sub-contractors on 2 of the days, which ordinarily would be a worry, but both parties were excellent and safety was at the front of their minds throughout.

Please pass on our thanks to your guys, the sub-contractors and also pass on my comments to your directors for another first class operation by SPEC Ltd.

Facilities Manager | Stelrad.


Could you pass on my compliments to your engineers for a great job today! The guys were a credit to SPEC in how they conducted themselves on site. Great customer service.

Having worked with SPEC Ltd on a number of occasions for installation, maintenance and break down situations, I can confirm that a high level of service has been provided at all times. SPEC Ltd has been able to react to the needs of our business in a timely and effective manner and is completely reliable.

T5 transformer move

SPEC were tasked with re-locating the transformer over the Easter weekend 2019 with work to be completed by 17:00 on the third day. 

Scope included re-location of T5 transformer and associated LV panel board, install a new 400A supply to the pumphouse and install 2 off 95mm DB supply cables. 

Project manager Paul Williams organised all works related to the project including the civils work. 

All necessary preparation work was completed with minimum disruption to site. 

I would like to thank Matthew Waltham (supervisor), Scott McQuaide, Mike Freeman, Tom Parkes-Brown & Tom Flavell for completing the work within the time permitted and for their level of professionalism.

Audits were carried out regularly while they were on site and we could see they had a positive attitude to safety.

 I have attached some photos of the work being undertaken.


Mark D, Electrical Engineer 

Thanks very much for providing a swift response to Thornhill CHP’s emergency issue last week and the technical support SPEC Ltd have provided has been vital to resolving the issue.

Richard Smith, Business Heat & Power Solutions | E.ON UK

I would like to highly commend you and your team for the excellent way in which the Polyflor High Voltage equipment replacement project was carried out.

This project was a total site replacement involving 15 Schneider switches across 2 substations and 15 1000kva transformers. I am happy to say everything about the project was managed professionally and always calmly with all issues being carefully controlled and actioned on time or in advance of requirement.

Planning was excellent and the attitude and helpfulness of Brian and the team was noted across the company including up to the director and board level. The project was finished three days earlier than expected, which gave the company bonus time to prepare post shutdown preparations.

The price, quality of workmanship and the high standard on documentation was also notable.

I would also like to say that in my experience it is rare to find a team that displayed such individual conscientiousness and attention to detail and safely along with obvious strong camaraderie, so they should be personally congratulated on that.

In summary Polyflor were more than happy with the project and would recommend SPEC Ltd to associates and personally I would look to work with you in the future if the opportunity arises.

Well done.

Project Manager, Polyflor

We have now reached the final snagging stages of our recent Transformer and Substation replacement project. At this point, I want to take this opportunity to thank all those involved at SPEC Ltd for their efforts in making sure this project was brought in on schedule and with the minimum of business disruption. Without exception, the guys on site conducted themselves with a level of commitment that deserves commendation. Even when things did not go to plan, they remained professional and did not allow the project timetable to slip.

XPO Logistics, Engineering Technician

SPEC is a well organised and reliable specialist High Voltage jointing, commissioning and protection organisation. We have successfully completed a number of projects in conjunction with SPEC Ltd in various locations throughout the UK and overseas.

Dave Friar, The Boulting Group Ltd

We commissioned SPEC for a specialist 33 kV jointing job. I found SPEC to be a very proactive company in establishing material supply and jointer knowledge to enable a speedy repair. I would highly recommend SPEC and their jointers for any future projects or substation failures.

Simon Rollason, BP

I just wanted to once again thank you and your team for their assistance over this weekend, which was pretty full on for everyone. Every one of the SPEC guys were professional, hard working and skilled in what they were doing. As on the previous shutdown we encountered a problem which had the capacity to sink our start up plans, but your team rallied round and sorted it again – I never doubted they would. I’d also like to thank your guys for the way in which they tidied up after themselves and left the substations very tidy.

Finally, I’d like to thank you most of all for the meticulous planning you put into this job, which we added to at the last minute with the additional oil changes – when I use contractors, I always check their paperwork and details and once again for this job, it was thorough, detailed and flawless.


As last time, can you please forward this on to your top management as a very satisfied customer and also pass on to all your guys my thanks for their professionalism.
