Septic Tank Emptying
Regular emptying of domestic and commercial septic tanks across Cornwall. Whoever does it must be a registered waste carrier. Most standard tanks take under an hour.
From £150Full tank in St Ives? An independent guide to septic tank emptying in St Ives and across TR26: what it involves, what it typically costs, and how to check a firm is a registered waste carrier. We’re not a septic tank company.
St Ives (TR26) and its surrounding villages — Carbis Bay, Lelant, Halsetown, Towednack and Zennor — sit on the north Cornish coast with conservation-area restrictions, steep cliffside properties and a lot of holiday-let activity. Many homes here rely on septic tanks or treatment plants rather than mains drainage.
Owners here need firms that can handle awkward access, tight lanes and cliff-edge installations — and, when tanks need replacing rather than just emptying, installers who understand the conservation-area constraints. Zennor and Towednack in particular sit on terrain that not every tanker can reach, so check the vehicle suits the property before you book.
St Ives town centre is one of the hardest places in Cornwall to get a tanker into — steep gradients, narrow one-way streets and heavy pedestrian traffic through the season. Most work here is done from the nearest accessible point with a long hose run, and timing outside peak hours makes a genuine difference.
The bulk of septic work in TR26 sits in the surrounding area — Halsetown, Towednack, Zennor and out along the north coast. These are exposed moorland and clifftop properties on narrow lanes, often with tanks a long way from the nearest hardstanding.
Like Newquay, St Ives runs heavily on short-term lets, and the same peak-season loading problem applies. Owners who empty on a schedule rather than on demand tend to avoid the August emergency callout entirely — and August is precisely when operators are hardest to get hold of.
We’re an independent guide, not a septic tank company. These are the honest options; pick whichever suits you.
Anyone who takes septic tank waste away must be a registered waste carrier. Whichever local firm you find, look it up on the Environment Agency’s public register before you book.
Ask for the firm’s waste carrier registration and check it, get a written price that says what’s included (disposal, hose length, access), and ask for a waste transfer note once the job is done.
Leave your details and we’ll try to introduce you to one local septic tank firm covering your postcode. We’re still looking for local firms to work with, so we may not have one for your area yet. We’ll tell you who before sharing anything, and septic tank firms may pay us for introductions.
Whatever’s going on below ground at your St Ives property, here’s what each job involves and what it typically costs.
Regular emptying of domestic and commercial septic tanks across Cornwall. Whoever does it must be a registered waste carrier. Most standard tanks take under an hour.
From £150Full cesspit pump-outs for sealed systems. Cesspits need emptying far more often than septic tanks, so the running cost adds up.
From £120New septic tank or treatment plant installation, fully compliant with the General Binding Rules 2020. Survey, install, commission: what a full job includes.
From £3,000Tank backing up, soakaway saturated, weird smells in the garden? Diagnosis via CCTV, then repair or replace: how to decide.
From £150 (survey)Blocked or slow-running drains cleared fast using high-pressure jetting. From kitchen sinks to main sewer lines.
From £80Camera inspections to diagnose blockages, root ingress, collapsed pipes, and drainage issues before they become expensive problems. A written report should be part of it.
From £150Prices depend on tank size, access, and your exact location. These are guides, not quotes: always get a written price before work starts.

Septic tank emptying in St Ives typically costs between £150 and £300, depending on tank size, access, and how far the specialist needs to travel. Cesspits usually cost more due to larger volumes. Emergency or out-of-hours callouts may incur an additional charge — always get a written quote up front.
Most domestic septic tanks in the St Ives area should be emptied every 6 to 12 months. A family of four with a 2,700-litre tank typically needs annual emptying. Smaller tanks, larger households, or heavy holiday-let use can mean more frequent service. Slow drains or odours usually mean it's overdue.
Some local firms can empty a tank the same day when their schedule allows, but it isn’t guaranteed, especially in peak season. Ring two or three firms that work around St Ives and say how urgent it is; calling early in the day helps.
You don't need a permit to have your tank emptied, but the waste must be disposed of by a licensed waste carrier registered with the Environment Agency. You can check any firm on the Environment Agency’s public register of waste carriers. Under the General Binding Rules (2020), your tank must also discharge to a drainage field — not directly to a watercourse.
This guide covers St Ives and the surrounding villages and hamlets across TR26, including Carbis Bay, Lelant, Halsetown, Towednack, Zennor, Nancledra and Hayle. We’re an independent guide, so we don’t send anyone out ourselves; look for a firm that works your patch and check it on the waste carrier register, or ask us for an introduction.
All waste is transported by licensed tanker to an approved treatment facility or sewage works. Whoever empties your tank must be a registered waste carrier with the Environment Agency, and you can ask for a waste transfer note as proof of legal disposal.
Routine emptying is unaffected — no permissions needed. Where the conservation area and coastal setting matter is replacement and installation work, which may face extra planning constraints, particularly on clifftop plots around Zennor and Towednack. Ask any installer how they'll handle those constraints before you commit.
With difficulty, and rarely right to the door. The streets are steep, narrow and busy. Most town-centre work is done with a long hose run from the nearest point a vehicle can safely stop, and doing it outside peak hours makes it substantially easier.
Usually, but ask when you ring. Zennor, Towednack, Halsetown and the clifftop properties along that stretch are exposed. They're exposed, often down long tracks, and worth booking with some notice rather than at the last minute.
