Tank Cleaning Tenders and Contracts

Tank cleaning tenders are contracts to clean, disinfect or maintain tanks such as septic tanks, fuel tanks, water storage tanks and swimming pool balance tanks. Work covers routine cleaning and legionella control, and one-off emergency clean-outs.

Stotles brings together tank cleaning tenders and contracts from 100+ portals into one search, so you do not have to check each portal separately, and you can set alerts for new opportunities across the UK and Ireland.

If you want to search the government portals directly, Find a Tender carries higher-value contracts across the UK and Contracts Finder carries lower-value contracts in England. Public Contracts Scotland, Sell2Wales and eTendersNI cover Scotland, Wales and Northern Ireland, Ireland's eTenders covers Irish public bodies, and many councils, NHS bodies and housing associations publish on their own e-tendering portals such as ProContract. Tank cleaning is often one element of water hygiene, legionella or fuel infrastructure contracts, while water companies let reservoir cleaning frameworks of their own.

Tank entry is confined space work under the Confined Spaces Regulations 1997, potable water work needs National Water Hygiene cards, and tank waste must go through licensed carriers under waste duty of care. Tenders usually set minimum insurance cover, check financial standing and ask for evidence of similar services at selection stage. Under the Procurement Act 2023, suppliers can be excluded for certain criminal convictions, insolvency or failure to pay tax.

Tank cleaning is bought both ways. Some buyers run a standalone tank cleaning contract, while others include it inside a wider water hygiene, legionella control or facilities management contract.

NHS trusts, councils, housing associations and universities are regular buyers. Contracts are also let by facilities management providers acting on behalf of public bodies.

Read water hygiene and legionella risk programmes, fuel infrastructure maintenance plans, estates planned maintenance schedules and expiry dates for existing cleaning contracts, which show work coming due ahead of a notice. On Stotles you can track those signals and the buyers behind them, then follow a notice from pre-tender through to award.
