Reading’s biggest drainage users are not shops. The Royal Berkshire Hospital has stood on the London Road since 1839 and runs a kitchen its own recruitment adverts describe as producing around 1,600 patient meals a day; south of the centre, Reading Gate Retail Park on the A33 and Brunel Retail Park on Rose Kiln Lane put around twenty units, fast-food outlets and coffee shops onto what are typically long private drainage runs; and the voco hotel beside the Select Car Leasing Stadium shares its site with a conference centre. A blocked drain at that scale is a blocked department, which is what TrueFlow’s commercial drain unblocking service is for; grease management and planned contracts are on the commercial drainage in Reading page.
What stops a large Reading site
Catering at institutional volume loads a drain as no restaurant does: a kitchen feeding wards or halls runs most of the day, so its fat never gets a quiet hour to flush through, and the deposit builds where the run slows, often well away from the sinks. Retail parks fail differently: one private run collects every unit’s waste before it meets the public sewer, so a coffee shop’s grease can close a furniture showroom’s toilets three doors down.
When the site cannot wait
The phone is answered at any time of the day or night, every day of the year. A blockage that is stopping a kitchen serving, a ward’s facilities working or a unit trading is an emergency: the engineer is dispatched against a 60-minute response target, and emergency attendance starts at £120 including VAT. A hospital kitchen does not close at six, and neither does the line that sends an engineer to it. A drain that is sluggish but still moving goes into the site’s quiet period, with the price settled before the booking.
Clearing it, and what it costs
Prices start at £80 for rodding an obstruction within reach of a chamber; £150 for high-pressure jetting, up to 4000psi, of grease, scale and anything well beyond it; £120 for a CCTV survey to show why the line blocked; and £220 for jetting and survey in one attendance. Each is a VAT-inclusive starting price; a long retail park run is quoted on sight.
The clearance itself is No Fix, No Fee. Where the camera shows the pipe behind the obstruction has collapsed, the invoice covers the survey and diagnosis alone, with nothing charged for the attempt. Whether the eventual cost lands with the occupier, the landlord or Thames Water depends on which section of pipe held the obstruction; the rules are in the guide to who is liable for a blocked drain.
The record and the next step
The site’s file gets the obstruction’s position, what it was made of, the method used and how the pipe was left, with photographs and any footage, and the invoice quotes the site’s purchase order number. Full insurance and a 6-month guarantee stand behind the work.
The record is the evidence an estates team needs to put the line on an interval, and a drainage maintenance contract matches that interval to how fast the run loads, so the next clearance is a diary entry rather than an emergency.
Reading commercial unblocking FAQs
What does the engineer need from the site contact on arrival?
Access to the affected fixtures and the external chambers, if their positions are known, plus the name of whoever is authorising the work. A porter or estates contact who knows where the covers are saves the most time; where nobody does, the engineer locates them.
Does a hospital or campus need to isolate anything before the engineer arrives?
No. The water supply stays on across the site and nothing is shut off in advance: the engineer works from the chambers and the affected fixtures, and the rest of the building carries on as normal. The one exception is a kitchen line, where the dishwashers are best held until the run is proved clear, so the backed-up section is not refilled while it is being worked on.
Can a purchase order be raised before the engineer attends?
Yes. The exact price is agreed by phone before the visit, giving the site a firm figure to raise an order against, and the invoice quotes that number. Where an emergency must be authorised before the purchasing team is in, the duty contact confirms the figure and the order number is added later.
Reading sites, cleared at any hour
An engineer can be on the way the moment 0808 175 7440 is answered, whatever the hour. If the blockage can wait for the quiet part of the week, send the site details through the contact form and the figure comes back before any booking is made. Domestic work is on the Reading plumbing page.
