What our customers say

★★★★★

Faced with daunting problems with our septic tank, and refusal by the insurance company to honour the claim, we turned to UKDP. Rob Brindley and the team took up our case and throughout a protracted period, due to insurance prevarication and very poor treatment and attitude by the insurers, Rob was totally professional, communicative, and tenacious on our behalf. It was a very long fight to get the insurance claim settled, but we won, thanks to Rob and UKDP. They moved heaven and earth (literally) to get a new sewage treatment plant installed before Christmas. Gareth and his team worked tirelessly and efficiently on the installation with minimum disruption. We can't thank Rob and everyone enough for their hard work.

We are in the middle of a full home renovation and have had literally hundreds of tradesmen and workmen at the house and none of them have been as lovely to have around as these guys. An absolute pleasure to have working here, always friendly and polite, answered any questions, gave as much time as was needed and went above and beyond to help with my endless questions and asks! Thank you so much.

Really respectful staff, very efficient and caused as little damage as possible. They left the site in excellent state and we could not be more grateful.

How often should a septic tank be emptied in Portsmouth?

Empty it at least once a year, or as often as the manufacturer recommends. On the chalk around Portsdown Hill, don't leave it longer: an overfull tank clogs the soakaway, and sewage can travel quickly through chalk.

Does home insurance cover septic tank replacement in Portsmouth?

Often, yes. Many buildings insurance policies cover sudden damage to septic tanks and drains, but not wear and tear. We check your policy and can help with the claim.

What are the General Binding Rules for septic tanks in Portsmouth?

Under the general binding rules, a septic tank must not drain straight into a river, stream or ditch. If yours does, you need to upgrade it: connect to the mains sewer, switch to a drainage field or fit a sewage treatment plant. You may also need a permit near drinking-water sources or protected wildlife sites, and we'll tell you which applies.

Who deals with off-mains drainage problems in Portsmouth?

If your home isn't on the mains, the septic tank or treatment plant is yours to look after. Southern Water only looks after the public sewers. UKDP handles emptying, repairs, surveys and replacements for private systems around Portsmouth.

What are the signs of septic tank failure?

Slow drains, bad smells, gurgling pipes, sewage backing up and boggy ground over the drainage field. Near the coast, a high tide or flood can cause the same signs, so get the system checked once the water has gone.

Can I get emergency septic tank repair near me in Portsmouth?

Yes. Our depot at Ford, near Arundel, is about 22 miles from Portsmouth. Call us on 0800 028 9903.

How much does a septic tank inspection cost near me?

A septic tank inspection costs £399 including VAT. Emptying, where needed, is charged separately.
