Sewer connections: how to choose the best contractor

Sewer connections aren’t an insignificant part of your build budget, whether your development is a single property or a large estate, so it pays to make sure you use the best contractor, for best value.

But how do you go about finding the best contractor (sometimes also called a ‘self-lay organisation’ or ‘SLO’)? Well, the first piece of advice is to start looking as early as possible. No matter whether a development is big or small, it’s important to have sewer connections completed at an early stage, as this will save time, money and hassle on site.

Here’s a checklist of tips we think will help you find the best contractor, which will also help save you time, hassle and money:

Certified to connect to public sewers

First and foremost, any self-lay organisation must have the proper accreditations in order to make a public sewer connection, as this is a legal requirement. SLOs can either be accredited by individual water companies, or via the Water Industry Registration Scheme (WIRS), which is recognised by all the water companies (we work with Southern Water, Thames Water and Anglian Water, amongst others), and Water UK.

Lengthy experience in sewer connections

As any drainage errors are invasive and expensive to correct, getting it right first time is important. There’s no better way to ensure this than choosing the best contractor for the job, with the most experience.

End-to-end service

Look for an SLO that offers a service that begins with the initial enquiry to the water company, and continues through the application and design stages, takes care of the process through notification and installation, and ensures that the sewer adoption procedure is followed through to its conclusion.

Free initial advice

Receiving advice on your sewer connection, and the most efficient and economic way to achieve it, should just be a part of the process, before you commit to spending money with a particular contractor. We’re happy to provide free advice on projects large and small, simply get in touch.

ISO quality management accreditation

There’s no better mark of good management practices – and therefore the best service – as the ISO 9001 accreditation. This standard is based on exemplary quality management principles including a strong customer-first ethos, management proficiency, robust processes, and a focus on continual improvement.

High standards of training

Don’t be afraid to ask for proof of previous customer satisfaction – a self-lay organisation that provides a high quality of service and installation will have a healthy back catalogue of projects with satisfied developers and homeowners ready to put their name to that fact.
