BEFORE YOU BOOK

Check before you book

No register applies

No licence or register applies to drainage contractors in any UK nation, so anyone may offer drain unblocking. The checks that matter are whose drain it is, the contractor's insurance and a written record of what was found.

Ask for the business name, the insurer and a written report or invoice for the drain unblocking.

Whose drain it is

In England, council guidance explains that from 1 October 2011 sewer pipes outside property boundaries, and pipes shared with a neighbour, passed to the sewerage company; you remain responsible for pipes that serve only your home and sit inside your boundary. That can decide who pays for the drain unblocking.

Before paying for the drain unblocking, ask the contractor whether the fault is in a drain serving only you, or a shared or public one. hinckley-bosworth.gov.uk →

Urgent call-outs and cancellation

An urgent call-out you asked for to clear a blocked drain is excluded from the 14-day cancellation right by regulation 28 of the Consumer Contracts Regulations 2013; a booked, non-urgent visit agreed by phone or online normally keeps it.

Agree the price for the drain unblocking in a message before the visit. legislation.gov.uk →

VAT

Unblocking a drain is standard-rated at 20%, including jetting and any camera check afterwards. Over the £90,000 registration threshold a trader must charge it and show it separately; under it there is no VAT and no VAT number.

Ask whether the fixed drain unblocking price is with VAT or plus VAT, and for the VAT number. gov.uk →

“Is the drain unblocking a fixed price or by the hour?”

A good answer: A stated basis, before the van arrives.

“What does an evening or weekend drain call-out cost?”

A good answer: A stated uplift.

“Is the blocked drain section mine or shared?”

A good answer: Their view, and advice to call the sewerage company if it is shared or public.

“Will you clear the drain with rods or jetting?”

A good answer: Rods for a simple blockage; jetting for grease and roots.

“Will you check the drain flow afterwards?”

A good answer: Yes, by running water through.

“Do you recommend a camera survey?”

A good answer: Only if the blockage keeps returning or there are signs of damage.

Leave the reviewReviews on Locufy are tied to a booking, so yours about the drain unblocking carries weight. If something is not right, the make-it-right step gives the drain unblocker the first chance to fix it before it is published.

STEP 1Complain to the drain unblocker firstSay what is wrong with the drain unblocking and what you want done about it. Under section 49 of the Consumer Rights Act 2015 the drain unblocking had to be carried out with reasonable care and skill; if it was not, you can ask the drain unblocker to put it right at their own cost (section 55) or for money off (section 56).
STEP 2Use the make-it-right stepRate the drain unblocking below four stars and you are asked whether the drain unblocker should see the complaint first; we keep it moving until it is answered, then you review.
STEP 3Trading Standards, through the helplinesA drain unblocker who will not engage can be reported through the consumer helplines, which pass cases to Trading Standards — Citizens Advice (0808 223 1133) in England and Wales, Advice Direct Scotland (0808 800 9060), Consumerline (0300 123 6262) in Northern Ireland.
STEP 4Small claims, if money is owedAn unpaid refund or repair bill from the drain unblocking goes to small claims: £10,000 is the limit in England and Wales, £5,000 in Scotland using simple procedure, and £5,000 in Northern Ireland — all designed to be used without a solicitor.

Hiring a drain unblocker: questions people ask

No. No register applies to drainage contractors.

In England, since 1 October 2011, shared drains and those outside your boundary are the sewerage company's responsibility.

An urgent call-out you asked for is excluded from the 14-day cancellation right. For a booked non-urgent visit agreed by phone or online, you normally have 14 days, but you pay for work done if you asked it to start straight away.

£80–£250 per job in normal hours, with £180 typical. The drain unblocking price guide explains the range; your town in the search box above shows drain unblockers who cover it.

When blockages keep coming back or there are signs of damage.

Under an hour for a simple blockage, one to two hours for jetting.
