Soakage test cost UK — BRE 365 prices explained

Homeowners comparing BRE 365 soakage test prices often see a headline figure that leaves out the digger, a second day on clay, or a deeper pit. Here is how Acorn’s Preston / Lancashire package is priced.

Standard package

From £850 + VAT — one trial pit about 1.2 m deep, machine-dug with our crew (our micro digger fits gates from 75 cm), three BRE Digest 365 fills using water from your outside tap, backfill and a tidy site, plus a branded Acorn PDF report (pit log, photos, readings, soakage rates and design soakage rate).

Most tests finish in a day. Slow ground such as clay may need a second day at £400 + VAT, so the most you pay for that standard one-pit (about 1.2 m) package is £1,250 + VAT.

Optional extras

• Deeper test pit (1.2–1.8 m) — from £150 + VAT extra
• Each extra pit on the same visit — from £350 + VAT
• Breaking out hardstanding — from £150 + VAT
• Deeper than 1.8 m — by quote only
• Reinstating turf, paving or surfaces — quoted separately

We test at the depth your soakaway will sit, up to 1.8 m, with readings from the surface.

What the price does not include

Soakaway sizing, drainage design, engineer sign-off or a competent person certificate. If you want us to install a soakaway or French drain afterwards, that is quoted separately on our garden drainage service.
