About KLT Construction

As the leading and largest utility contractors in Southern England, KLT Construction is the ultimate one-stop-shop utility provider.

Delivering in excess of 8,000 metres of gas mains replacement and over 700 services and associated works every week, KLT is committed to delivering projects safely, on time and within budget.

Predominantly specialising in gas renewal and infrastructure maintenance, KLT has gained a strong reputation as one of the leading providers in the utility industry. Customers choosing KLT know they are picking a gas utilities specialist that delivers a professional, safe cost-effective and time-efficient service.

We carry out repair and maintenance works, gas infill projects and new pipelines installations, the provision (or hire) of vacuum excavation services, specialist mains drilling, gas stopping services and governor installations.

With a combined workforce of over 1000 people, KLT is regarded as one of the largest industrial construction companies for its region. There are close to 200 gas teams specialising in above and in-ground works, comprised of NCO 1, service and main layers in various diameters.

Our 200 engineering teams carry out mains service repair, and replacement services for utility providers and main contractors including SGN, Cadent, tRIIO, Skanska, Morrison Utility Services Limited and Matrix Networks Limited.

The replacement of existing metallic gas mains with new plastic mains, is at the core of KLT’s work. The new plastic mains, which offer safe and reliable gas supply for at least the next 80 years, are installed, where possible, with live insertion to minimise excavations and ensure as little inconvenience and disruption as possible. Where these methods are not possible and the lengthier process of open cutting ground is the only available option, we use vacuum excavation and our in-house waste haulage and reinstatement teams to ensure we finish in the shortest possible timeframes and with the best finishes to affected surfaces. In most cases KLT helps clients complete work sites within a day of the engineering works being completed.

KLT Construction is part of the KLT Group, a private limited company, established in 1997, by the founder and current C.E.O, Robert Taylor. Operating from the Head office in Hemel Hempstead, there are subsidiary depots in Slough, Stanwell, Kings Langley, Godstone and Tilbury.

“Thanks for making my experience with the Gas company such a good one.”

G. Wood, Kent

“I was so happy with the service I received.”

Sue, Epsom

“We have found the guys in this gas repair team courteous and helpful. It must be a difficult job for them working in this heat and sometimes heavy rain. It has not always been easy for us to park in the road but the team have done their best to accommodate us.”

A. Totty, Shepperton

“Just a quick e-mail to say thanks to all the KLT team for their excellent work in Boughton Hall Avenue. The job has been executed to a very high standard, and considering the scale of the work, with minimal disruption to the residents. The team has been excellent – very happy to explain their work and to go into the technical aspects of the job. Our own newly paviour-blocked drive had to be excavated to secure a connection to the main for a neighbour and the re-instatement has been “invisible”. Similarly, all through the Avenue the team has used good quality turf for re-instatement in the grass verge, and the only excavation into the road surface itself has also “disappeared”.

A. Hutchinson, Woking

“I’m a resident in  Teddington were your workmen are doing the gasworks at the moment. I wanted to email you to say how impressed I’ve been by them. They are friendly, thoughtful and extremely tidy whilst carrying out these major works.”

Mrs King, Teddington

“Your company has been undertaking work in our road and I wanted to say that Aaron and Craig have been delightful. Friendly, polite, communicative – and event went to the trouble of trying to alert neighbours to the fact that our front door had been left wide open!! Impressive!”

R. Moore, Wimbledon

“I hope that you have an employee/s for the month award and would like to nominate Aaron and Craig who have been working in Wimbledon for the last few weeks. Always smiling they have been happy to answer questions and explain what was happening and what they were doing. I would also say that they have tried to sweep the area clean at the end of the day. A credit to your company.”

R. Earland, Wimbledon
