Drainage and CCTV drain survey software: a UK guide

Last updated: August 2026

Half past seven on a Tuesday and the phone goes: sewage standing in a back garden, a terrace of six. You are there by nine, lift the cover in the alley, and it is the shared run rather than her own drain. In England that pipe has belonged to the water company since 2011, so the honest answer is that she owes you nothing and should ring them. Two hours of your morning, no invoice.

Meanwhile the homebuyer survey booked for ten has slipped to eleven, the conveyancer has an exchange date, and last Thursday’s footage is still on the card in the van because nobody has written the report.

Nobody knows who pays until someone lifts a cover

For a large share of domestic blockage callouts in England and Wales, your customer is not the payer. SI 2011/1566 came into force on 1 July 2011, and under the main scheme the transfer took effect on 1 October 2011, vesting private sewers and private lateral drains in the sewerage undertaker.

The qualifying test is narrow and almost nobody states it. A pipe transferred if, immediately before 1 July 2011, it communicated with a public sewer; anything connected later falls to a supplementary scheme. Two definitions decide the rest: a private sewer serves more than one property, and a private lateral drain is the length serving a single property that runs beyond its boundary. The drain inside the boundary serving only that house did not transfer. Private pumping stations transferred no later than 1 October 2016.

Thames Water states the customer’s half plainly: you remain responsible for the pipe between your building and the transferred sewer or lateral drain, and for internal plumbing. It also warns that a customer can be charged if the company investigates and the fault turns out to be theirs. Invoice a householder for a transferred lateral and you have billed for work the undertaker would have done free; send them away too quickly and you have given away a chargeable job.

It is not one national answer. In Scotland the older split survives: Citizens Advice Scotland puts the owner’s responsibility up to the point the pipe connects to the public sewer, normally at the boundary, and shared pipes are a title deeds matter. Northern Ireland has had no equivalent transfer at all: a shared run behind four terraced houses in Belfast is still the joint responsibility of the four owners it serves.

The house side of that boundary is a different guide: job management software for plumbers covers internal pipework and boilers.

The survey report is the product, not the paperwork

A CCTV survey is not a diagnostic step you throw in. It is a saleable deliverable, bought by homebuyers, conveyancers, insurers and property managers, and read weeks later by somebody who was never on site.

That deliverable has a defined shape. WRc created the first image coding structure in 1980 and the Manual of Sewer Condition Classification is now in its 5th edition. Compliant reporting software codes observations to MSCC5 and BS EN 13508-2, and assessment produces an SRM internal condition grade and operational grade for each pipe section on a scale of 1 to 5, where 5 is worst. Codes describe; grades score.

Two things are widely misunderstood. WRc Approved status sits on the reporting software, not on the contractor, so no firm is WRc Approved. And a CON29DW drainage and water enquiry is not a survey: it reports what the water company’s records say about connection and ownership, and never puts a camera in the pipe.

In practice a full report carries a cover page, a plain English summary, a pipe by pipe breakdown, MSCC5 defect codes, condition grades, annotated stills, a schematic or CAD drawing showing routes and manholes, and the video itself. WRc is blunt that the weak link is interpretation, and runs surveyor training at three levels for that reason.

For the business rather than the surveyor: on insurance and conveyancing work, no report means no payment, so turnaround is a cash flow metric rather than an admin one. A firm selling reports is also selling professional opinion, so a defect missed on a homebuyer survey is a claim against the report rather than the workmanship.

Two calendars competing for one van

A booked survey with an exchange deadline and a sewage emergency want the same van on the same morning. The emergency wins, and the customer whose goodwill you spend is a conveyancer, an insurer or an agent, which is to say a repeat referrer rather than a one off householder.

Three things make it harder than a normal reactive round. A CCTV survey has no reliable duration: a 25 metre domestic run and a 300 metre commercial network occupy the same line in a diary. Crew composition changes per job, because jetting needs a trained operator and a unit, entry needs a team, and a patch liner needs curing time standing still on site. And tanker and disposal capacity is a second invisible schedule: a full tanker cannot take the next job, and the tip has opening hours.

The practical answer is a diary that shows the whole week at once, on a phone, with the assignee and the site on each visit, and that lets you move a booking without losing the customer who was told. Work for managing agents brings its own access problem, since the caller is often neither the payer nor the keyholder; property maintenance for letting agents covers that arrangement.

Confined spaces, jetting and the waste that follows the van

The Confined Spaces Regulations 1997 name this trade’s workplace in the definition itself. Regulation 1 covers any chamber, pit, trench, pipe or sewer whose enclosed nature gives rise to a reasonably foreseeable specified risk, such as loss of consciousness from gas or lack of oxygen, or drowning from a rising liquid level. It is the risk that triggers the Regulations, not the depth or the label on the chamber, and a five minute job is not exempt.

HSE sets three duties: avoid entry where the work can be done from outside, follow a safe system of work where entry is unavoidable, and put adequate emergency arrangements in place before work starts. That last one is a rescue capability: people and equipment, not a form. It is also the strongest commercial argument for a camera and a jetting lance, which are the “do it from the outside” answer. Northern Ireland firms need SR 1999/13, not the Great Britain instrument, and jetting competence follows the Water Jetting Association’s codes, an industry standard rather than a statutory licence.

Waste is the second document trail. Carry other people’s waste in the course of business and you must be registered with the Environment Agency, normally upper tier for a contractor lifting gully sludge, renewed every three years, with an unlimited fine for not registering. Scotland and Northern Ireland set their own fees. The waste duty of care code of practice then requires a transfer note for each non hazardous load, kept two years, a consignment note for most hazardous movements, kept three, and a check that the next holder is authorised before you hand anything over. Sewage cleaning waste and septic tank sludge are non hazardous entries; interceptor and forecourt separator contents may not be, which changes the note, the retention and the route.

The pain is never raising the note; it is producing it two years later against a job number nobody remembers.

Pricing an unknown, then answering CIS job by job

Every other trade can see the work before quoting. You cannot, because the defect is underground and the difference between a rod and an excavation is invisible from the driveway. Published consumer guide prices, which are aggregator figures rather than survey data, put a callout at £50 to £100, rodding at £80 to £145, a CCTV survey at £90 to £350, and a collapsed drain repair at around £850. That spread is the whole business model in one row: sell the diagnosis first and the cure second. It is also why “no fix, no fee” is worth naming as a trap, since it moves the cost of an unsuccessful visit onto you.

Then there is the tax answer, which changes per job rather than per customer. HMRC treats sewers as works forming part of the land, so constructing, altering or repairing a sewer is a construction operation within CIS. A building’s own drainage is a building service system instead, and CISR14090 covers its installation only, so repairs to it fall outside CIS. The boundary is the point where the property’s drainage joins the main sewer, which is the same physical point that decided who pays in the first section of this guide.

The VAT domestic reverse charge then follows the CIS answer: it applies only to supplies reported within CIS, and not where the customer has confirmed in writing that they are an end user. Householder work is never in scope. Subcontracting an installation to a groundworker probably is. CIS invoicing for subcontractors covers the mechanics; the point here is that the same builder can need two treatments in one week. Check your position with your accountant.

How Dispatch helps

Dispatch runs the callout, the customer, the photographs and the money around your survey report, so the reporting software you already use keeps doing the coding and everything else stops being scattered.

One job record holds the customer, the site address, the priority, the booked visit, notes and photographs, with quotes and invoices raised from it. Send a private link and the customer describes the problem with photographs before you roll, or open a two way message thread where they can send more while you are en route. Book onto a week calendar where an emergency dropped into a booked day warns rather than blocks.

On site, a completion report captures the write up and up to twelve photographs before the job closes, so what you found is recorded while you are still standing over the chamber. Survey reports, quotes for the repair and any certificates attach to the job and are kept for its life.

Then quote the lining or the excavation, invoice from the phone, and take card payment into your own Stripe account. Overdue invoices chase themselves at 3, 10 and 21 days, which matters when the report is the product and payment waits on it.

Every feature is on every plan, everything runs in the UK, and there is a free plan to try on one callout.
