How to Choose a Septic Tank Company in Greater London
With 15 registered companies to choose from in Greater London, here are the key things to check before booking:
- EA Registration: Confirm the company holds a current Upper Tier waste carrier registration. All companies listed above are verified, but you can also check the EA public register directly.
- Tank access: Ask about access requirements. Some companies need a clear route for the tanker within 30 metres of your tank. Mention any narrow lanes, gates, or soft ground.
- Tank size: Know your tank capacity (most domestic tanks are 2,700-4,500 litres). Larger tanks cost more to empty. If you're unsure, the company can assess on arrival.
- Disposal certificate: A reputable company will provide a waste transfer note after every emptying. Keep these as proof of compliance—you may need them when selling your property.
- Regular schedule: Many companies offer annual contracts at a discount. The Environment Agency recommends emptying at least once a year for most households.
What Does Septic Tank Emptying Cost in Greater London?
Typical septic tank emptying costs in Greater London range from £150 to £300 for a standard domestic tank (up to 4,500 litres). Larger tanks (9,000L+) cost £300-£450. Emergency or out-of-hours callouts may carry a premium of 50-100%. Cesspit emptying is more expensive due to higher volumes—expect £150-£400 per visit depending on capacity.
Prices vary between companies, so it's worth getting 2-3 quotes. Distance from the disposal site, ease of access, and tank condition all affect the final price.
When to Book an Emptying
Most septic tanks in Greater London should be emptied every 12-18 months, though households of five or more may need it annually. Cesspits require much more frequent emptying—typically every 4-6 weeks. Book early in autumn before the winter rush, when demand spikes due to wetter ground and higher indoor water usage.
Warning signs your tank is overdue: slow-draining sinks or toilets, foul odours near the tank or drainage field, soggy ground around the soakaway, or gurgling pipes. If you notice sewage surfacing, call one of the companies above immediately.
