What to expect

Inevitably, the scale of KLT’s essential gas utilities work and infrastructure maintenance means some disruption to the immediate environment is inevitable. Here’s what to expect when we send in our teams.

Ground Excavation

KLT, (in conjunction with utility drawings and visual aids,) uses sophisticated locating equipment to scan the ground and identify gas utilities that are already present, before using a water-based degradable spray to mark the identified cables and pipes. The spray’s markings will wear away within a few weeks of KLT leaving a site.

To minimise disruption, before using any of our excavation methods,we use internal cameras to inspect the condition of the carrier main and pinpoint the location of the services.

Large excavations, known as connection holes are usually in the road and left open throughout the infrastructure maintenance and gas renewal works. They are essential as the point we introduce gas into the new pipework.

Access to Property

Once the pipes are installed in the ground, KLT will need access to your property to connect your internal pipework to your new supply. This will involve a skilled team member and a Gas Safe engineer to assess the condition of your existing pipes and appliances and, if everything meets the requirements, carry out the final connection of the pipes. The engineer will complete this gas utilities work within four hours of the interruption of the supply. Please note: this process applies to domestic property but doesn’t cover multiple occupancy premises, such as flats, maisonettes and workplaces.

Recycling & Reusing Waste

Because we recycle and reuse as much excavated waste as possible, all KLT works use compound shipping containers. These are placed in a designated work space by the Local Authority (LA); please note KLT has no control of the location. We are also legally required to have a self-contained mobile welfare unit.

Completing The Job – Reinstatement

Within a day or two of the engineering works completion, we will backfill the lower ground to the pre-works surface level (this and all public reinstatement is done in line with the LA/HAUC specification) before following up with the final surfacing work.

As one of the largest construction companies in the building and construction and gas renewal industries, KLT prides itself on completing work – and associated disruption – in minimal amount of time, above the industry standard. We typically complete our reinstatement within two to three days of the final interruption of gas supply – and in most cases we aim to conduct these works within one day.

Please note, low level concrete needs to cure before we can carry out final surfacing works, and will affect how quickly we can complete on these projects.

The final stage of our work is to clear the site of our barrier system, signage and associated equipment, leaving the work area as it was before works began.


Our reinstators and management carry I.D cards for the gas network that they are working on, it is your prerogative to ask to see this, please do not let anyone access your property unless they can show you an in date, relevant I.D card and then call the number on the card to verify the user.


To ensure we consistently offer the best service possible, we, at KLT, rely on your feedback. It’s possible you may be contacted by OFGEM to fill in a survey. Please do and help us to be one of the best industrial construction companies.

At any stage of KLT works, if you have any questions or enquiries please don’t hesitate to ask the various site personnel as outlined in your advance notification documentation. You can also call our customer service team to discuss anything you need help, support or clarification on. Please see our Customer Care page.

“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
