Standard criteria

If you are building near a public sewer and can meet the criteria below, then you can proceed with your project without having to notify us.

Meeting the criteria

You will need to meet all six of the listed criteria and it is important that you thoroughly review each point. The implication of proceeding on the basis of an inaccurate response can be significant and may make it more difficult to sell your house in the future.

Please note that the criteria does not apply if you are building over a public sewer. Find out what you need to do if you are building over a public sewer.

We have summarised the six criteria below, and there are helpful tips and diagrams to explain each one. We recommend that you discuss them with an architect or builder.

Important: You must meet all six of the following criteria.

I meet the criteria

If you have met all six of the criteria, a printable PDF of these conditions should be saved for your records. If your development requires Building Regulations approval, you can provide a copy to your local Building Control department or Private Inspector.

We also recommend you collate and store evidence (photos and drawings) that you have met the six criteria. This will provide you with peace of mind and protection in the unlikely event that something goes wrong in the future.

I don't meet the criteria

If you didn’t meet all six of the criteria, where possible, you should first consider changing your design until it does. If you still can’t meet the criteria, you will need to contact us to obtain formal consent for your proposal. The type of application that you need to make will vary depending on your site circumstances.

So that we can give you accurate advice, please email and provide as much detail as you can, preferably including design drawings or a sketch which clearly illustrates the details of your proposal.
