Am I entitled to a free supply pipe repair under the Leak Repair Scheme?

On our first visit we will make an assessment and decide if we can offer a free repair. If we find out from the assessment that there is a good chance of locating the pipe at the point where the leak is visible, we will dig down and try to find the leak and if possible we will try to repair it. In some cases this may only be temporary for example the pipe may already be in poor condition and the whole pipe should be replaced. A repair will only be effective if the leak is small, visible and the pipe is in good condition.

You are usually entitled to only one free repair, and the decision to repair the leak is at our discretion and we do not guarantee to repair a leak on your supply pipe. If we can make a permanent repair, you may be eligible for a second repair attempt, if needed, provided the pipe work is still in good enough condition.

If we try to dig and find we cannot locate the pipe or it is obstructed we have to abandon the work, make it safe and re-fill the hole unless you request otherwise. Then we will advise you on what to do next.

Please note in all cases where we work, we will refill the hole and make it safe, but we will not reinstate the area to match the existing finish, e.g. with matching materials, nor will planting be replaced or restored. You will be responsible for carrying out works needed to restore the area.

If you have been issued with a waste water notice then you will not qualify for a free repair, possibly for any of the following reasons:

  • The leak is not visible or we are unable to locate it.

  • There is a physical obstruction, e.g. a conservatory or outbuilding.

  • The age and condition of the pipe work means a replacement pipe is required.

  • We have already repaired the supply pipe on more than one occasion.

Should I repair or replace my supply pipe?

If the leak is serious or your supply pipe is old and in a bad condition, you’ll need to decide whether to repair or replace the pipework. A repair is usually the best option if the leak is small and your supply pipe is in good condition.

If the pipe is fairly old, it’ll probably need to be replaced – and may be eligible for a subsidy, to find out more please contact us.

If your property is on a shared supply with your neighbours, the decision to repair or replace will need to be agreed by all the responsible parties. All parties on a shared supply are eligible for a subsidy towards replacement provided that the whole pipe is renewed.

How do I deal with a leak if I am on a shared supply?

We recommend you talk to your neighbours to discuss the repair at an early stage. If you are considering replacing an old supply pipe, it may be worthwhile considering having an individual supply pipe installed. In general, replacing the shared pipe will be cheaper, but there are some potential problems that you need to be aware of:

  • If the stop tap on the street needs to be closed off, all properties connected to the pipe will be without water.

  • The water use in one property may have an adverse effect on the water pressure in another property (although good design can often help to avoid this situation).

  • It is not possible to add more properties to the existing shared supply.

Is there any help available?

If you are on a water meter, you usually have to pay for water lost from your leaking supply pipe. However, if you’ve done everything you can to repair a leak as quickly as possible – and you notify us before you carry out the work – we may amend your bill so that you don’t have to pay for the wasted water. We call this a Leak Allowance.

Please note that you won’t be eligible for a Leak Allowance if:

  • The leak was caused by your negligence

  • You took too long to repair it

  • You knew about the leak (because it was visible) but failed to repair it

  • You should have known about the leak and failed to repair it

  • We have made a previous allowance for leaks

  • We had previously recommended that you replace the pipe but you failed to do so

  • Your supply is commercial

  • The leak occurred as a result of faulty pipes or fittings in your property

We will not adjust your bill for leaks that have arisen from internal pipework and fittings unless, in some case, the leak was not visible and you were not aware of it, or if you have claimed for a Leak Allowance before. If you are concerned about further leaks on your supply pipe, or about losing water from internal pipes and fittings, you may wish to investigate taking out insurance to cover the cost of lost water.

How to claim a subsidy

To be eligible for a £100 contribution towards the cost of your repair, you must first inform us that you have found a leak on your supply pipe. Depending on your comments and findings we may not need to attend your property to confirm this. If you are uncertain about the leak we will visit the site and advise you.

To qualify for the payment you must complete the renewal of the entire supply pipe from the internal stop tap to the boundary of your property. You will need to do this within 21 days of the date on which you first informed us of the leakage. A claim form will be sent to you asking for your bank details. You must return this claim form within 21 days of notifying us that the supply pipe has been renewed.

Please note if you are on a shared supply then all the responsible owners have to renew their part of the supply pipe for everyone to qualify.

What happens if I don’t repair the leak?

It is our responsibility to prevent any loss of water and notify the property owners about any leaks we may detect. The person or company responsible should arrange and pay for the leak to be repaired.

If the leak is not repaired we may serve a legal notice under section 75 of the Water Industry Act 1991. The notice advises the property owners of their responsibility to repair the leak within a specified date. If the leak is not repaired by the date we will arrange a repair ourselves, if necessary we may get a warrant to get access to the property. We will choose a contractor to do the repair and all costs we incur will be charged to the property owner.

Please note: It is important repair your leak quickly to avoid any unnecessary costs and legal action.

Why have you sent me a notice?

We attempt to notify the property owner about any leaks we may detect, either by a phone call or in person from one of our community teams. If we cannot contact the owner by phone or in person we will send a leakage notification letter. If you received this letter of a Waste Water Notification then it is because we believe you are responsible for the leaking pipe work on the property.

If you are not responsible for repairing the leak, for example if you are a tenant who is not responsible for repairs, please contact us on 0345 3572409. We would be grateful if you can provide details of who is responsible for repairs, for example your landlord, council or managing agent.
