Who obtains all of the approvals?

We can do this on your behalf, including the application to your local water authority (e.g. Thames Water) for consent, to the local council for any permits/licences; and obtaining sign-off from the local water authority. The administration in making any applications is included in our service. We can make allowance in the quotation for the council fees.

Are all works signed off by Thames Water?

Yes, we will arrange the sign off from Thames Water and provide you with the Completion Certificate once works are complete. We hold all of the necessary insurances and qualifications, and can liaise with Thames Water on your behalf.

How long does it take to get a quotation?

We aim to provide a quotation within one working day of carrying out a site visit/survey.

How long does the whole process take?

Refer to the process diagram above for how long each stage can take.
 
Once our quotation is accepted and depending on the type of project and works required, NG Tunnelling will make the application for any permit(s)/licence(s) to the council. Note that each council varies in their lead time to grant/approve these.
 
If council permits/licences and traffic management are not required, you already have the required drainage drawing(s)/plans(s), and consent has already been granted by your local water authority, there is potential for NG Tunnelling to start work on site with even just a few days’ notice.

How long do the works take to carry out?

The average sewer connection for a new build development can be carried out within a week’s duration and is determined by the depth of and distance to the main sewer.

How much do the council fees costs?

The cost of the fee and deposit for any necessary permit(s)/licence(s) vary by council but we can determine these exact costs on your behalf.

How do I ensure the works are guaranteed?

NG Tunnelling hold £10 Million Public, Products and Employer’s Liability insurances. All works are certified by Thames Water on completion, ensuring the works will be adopted and maintained by Thames Water.

‘We were very happy with the service and workmanship carried out by NG Tunnelling and have no hesitation in recommending them. Very happy with the professional and knowledgeable staff/workers.’
