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 Newquay? An independent guide to septic tank emptying in Newquay and across TR7 and TR8: 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.
Newquay (TR7, TR8) has a busy seasonal coast but a quiet, rural hinterland — and a lot of holiday lets and farmhouses across Quintrell Downs, St Columb, Crantock, Cubert, Mawgan Porth and Holywell Bay rely on private drainage.
Holiday-let owners around Newquay feel this most, because tank levels spike during high season and a backed-up tank in peak summer is the last thing anyone needs. Firms book up around peak-season changeover days, so give as much notice as you can, or get the tank emptied before the season starts.
Newquay's off-mains properties are disproportionately holiday lets and parks, and summer occupancy fills tanks two to three times faster than normal household use. The single most common call here is an owner discovering in July that a tank sized for a household is not sized for a full house of guests.
Because of that, most owners around Crantock, Cubert, St Mawgan and Colan book emptying against changeover days rather than on a calendar schedule. Peak-season slots go quickly — operators covering TR7 and TR8 are busiest exactly when you need them, so notice matters more here than almost anywhere else in Cornwall.
Sandy ground near the coast drains differently from the clay further inland. That's usually good news for soakaways, but it also means a failing drainage field can go unnoticed for longer because the symptoms are less obvious. If your tank is being emptied noticeably more often than it used to be, that's worth mentioning.
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.

Septic tank emptying in Newquay 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 Newquay 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 Newquay 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 Newquay and the surrounding villages and hamlets across TR7 and TR8, including Quintrell Downs, St Columb, Crantock, Cubert, Mawgan Porth, Holywell Bay and Goonhavern. 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.
Yes — it's the most common need for Newquay holiday-let owners. Summer occupancy fills tanks two to three times faster than normal household use, so firms book up quickly in peak season. Give as much notice as you can and ask for a slot that fits your changeover.
Almost always occupancy. A tank serving a household of four and the same tank serving a full holiday let are doing very different amounts of work. If occupancy hasn't changed, the other common cause is a drainage field that's no longer soaking away properly, which is worth having looked at.
Honestly, it's the hardest month of the year for it. Every holiday-let owner in TR7 and TR8 wants the same thing at the same time. If you can get on a scheduled arrangement before the season starts, you avoid the problem entirely.
