Hydrant Licence


If you need to draw water from a hydrant within our area you will need to apply for a licence.

You may only draw from our network if you have an Affinity Water issued licence. It is an offence under section 174 of the Water Industry Act 1991 to draw water without permission and we may take legal proceedings against unauthorised users. Unauthorised use increases the risk of contamination to the public water supply on our network, possible reduction in pressure, or even a mains failure.

Apply for a licence

We can offer an Annual Hydrant licence or a Short Term Hydrant licence. You will need a licence for each standpipe you wish to use.

We need between 7 to 10 days for your licence to be processed. We cannot fast-track applications, so please apply in good time.


Annual licence

  • Access to over 280 pre-selected approved points throughout the Affinity Water network. (if you are licensed to use these points, you must closely follow the Approved Washout List)

  • Licences run from 1 April – 31 March and you can apply at any time.

  • This option allows companies to fill up and transport water over short distances to the required site.

Short-term licence

  • You can specify which particular hydrant you want to access to for a period shorter than a year.

  • This option is more suited to companies who are working on a specific site

Please note it is against our Terms and Conditions to access any hydrant point other than those listed on the licence. If you use any other hydrant points, you may be charged for any unauthorised use and legal proceedings may be taken.



What happens after you apply

You will receive confirmation of charges and an inspection of the hydrant will be arranged.

Your licence will be issued subject to:

  • Satisfactory inspection of your equipment

  • Payment

  • Usage training
