How we chose
We built the candidate list from map listings across Telford, Companies House records and each firm's own website. Each business must first meet three basic checks: it is who it says it is, it is trading today and can be reached, and anything it claims by way of registration checks out. Eight firms met all three. We looked first at what customers say, then qualifications, then trading history and cover, with pricing clarity and website detail counting next. Every check in this round carries an early-September evidence date.
How to hire
Match the engineer to the symptom. A slow sink, bath or toilet alone usually needs drain clearance with rods or a jetter; sewage backing up through several fittings, repeated blockages or a collapsed gully points to a survey-first job with CCTV before anyone digs. Smells without blockage can mean a dry trap or failed valve rather than the drains, so describe every symptom when you call. Work on a septic tank or treatment plant needs a specialist in off-mains systems, not a general clearance van.
Check waste handling first, because your rubbish stays your legal responsibility even after it leaves your drive. Anyone taking waste, sludge or spoil away for payment must hold a waste carrier licence: open the Environment Agency public register, search the business name, and note the registration details before they load anything [1]. If the name is missing or the details do not match, say so and hold the job until it is settled. A firm with nothing to hide answers this question straight.
For work on supply pipework and internal plumbing that connects to the mains, look for WaterSafe approval as evidence of competence with the water fittings rules, and check the business name on the WaterSafe register [4]. Check limited companies on Companies House for active status and a matching trading name [7]. Ask to see public liability insurance and two recent local jobs like yours, with footage you can inspect.
Get the price structure agreed before the van moves. A proper quote separates the attendance fee, jetting or rodding labour, CCTV survey with footage and report, and any excavation or lining as a separate staged price, plus VAT [6][5]. Ask what run length the jetter handles, whether the survey recording is yours to keep, and what happens if the blockage cannot be cleared or the fault lies in the shared sewer. Agree access to chambers, lifting of covers, reinstatement of any dug ground, and a time window for emergency call-outs. Put the scope and the ceiling price in writing first.
Know where your responsibility ends. In most Telford streets you own the drain serving only your home up to your boundary, while Severn Trent owns shared and public sewers beyond it, so a blockage past that point is theirs to clear [2][3]. Check the water company's maps before paying for work on what may be their pipe. If a manhole in the street is overflowing, report it to the water company rather than paying a private firm to clear it.
After the job, keep the CCTV footage, the written report showing what was cleared and what defects remain, and the itemised receipt. A jetting visit that clears the symptom without reporting a cracked or displaced joint it passed is half a job [6]. If excavation crossed a neighbour's land or a pavement, confirm in writing who reinstates it and to what standard.
Telford and Wrekin adds its own layer. Eight conservation areas sit inside the borough, including the Severn Gorge, Wellington, Newport and Horsehay, where work that needs planning permission faces extra scrutiny and trees need six weeks' notice before any pruning or felling [8]. Alterations to drains fall under the building regulations, with foul and surface water kept separate and guidance in Approved Document H, so loop in the council's building control team before trenches are dug [12]. And any dig that breaks open a road, verge or footway needs a streetworks licence from the council as highway authority, with new sewer connections documented in the application [13].
A tidy job runs in the same order whatever the firm. First contact sets the symptoms, the postcode and the access picture: which fittings are affected, where the chambers sit, and whether cars or locked access block the run. The visit starts with lifting covers and tracing the run before any machine comes off the van, then clearance or survey, then the camera evidence on screen with the fault's position marked. Repairs follow as a separate staged price once the footage exists, and sign-off means the flow restored, the ground reinstated, and the footage, report and itemised receipt in your hands.
Judge the written quote on what it names. It should carry the firm's full name and contact details, each stage priced on its own with VAT shown, the start date and time window, payment terms including when the balance falls due, and what happens if the fault sits in the shared sewer or the blockage will not clear [6][5]. At the end, the paperwork that matters is the survey footage with the defect positions marked, the written report in plain terms, the itemised receipt, any guarantee on lining or excavation with its length and conditions, and a note of who reinstates dug ground and to what standard.
Pricing
As of autumn 2026, rough Telford guides look like this. Clearing a straightforward domestic blockage with rods or a jetter commonly falls between £90 and £200, while an emergency evening or weekend call-out often adds £80 to £150 to the attendance fee [6][5]. A recorded CCTV survey with a written report is frequently £150 to £350, and the recording is yours to keep.
Localised repairs such as patch lining often start around £400 to £800, while excavation and replacement starts in the high hundreds and climbs with depth, surface and length. Recurrence moves the price most: a one-off blockage costs little, while roots, displaced joints and bellied pipes need repair rather than another jetting visit. Access, depth, whether a chamber must be rebuilt, and disposal of spoil all shift the total. Get each stage priced on its own, so a dear repair cannot hide inside a low headline figure.
Jetting is the step up from rods for grease, scale and stubborn external runs. National guides put a jetting visit at around £120 to £250 on its own, moving with run length, how stubborn the build-up is and how awkward the access is [10]. A basic camera look without a report costs less than a full survey with footage and report, which the guides place higher [11]. Combination visits with rods and jetting together land higher still.
No-dig repairs trade digging for resin. Guides put relining at roughly £85 to £150 per metre of pipe, which suits a cracked or displaced section with sound ground around it [10]. Full excavation and replacement is a different scale of job, moving with depth, surface, length and reinstatement, and any break into the road or footway brings the council's streetworks paperwork into the price [13].
Off-mains homes pay for the tanker as well as the engineer. Emptying and disposal move with tank size, the length of the hose run from road to tank, and how full the tank is when the tanker arrives. Treatment plants add servicing and parts on top of emptying, so price the visit and the service plan as separate lines.
Get attendance, clearance, survey footage and any repair priced as separate written stages with VAT shown, since published guides exclude it, and treat pressure to authorise digging before the camera footage is shown as a reason to pause [6][1]. Confirm what happens if the blockage cannot be cleared or the fault lies in the shared sewer, whose repair sits with the water company [2]. Never pay the balance until the footage, the report and the itemised receipt are in your hands.
Red flags
Recommends excavation before running a camera, or quotes a dig from the doorstep without footage showing the fault and its position.
Cannot show a waste carrier licence number, or brushes off the question of where the spoil and sludge they remove ends up [1].
Clears the blockage but offers no recorded survey, no written report of defects passed along the way, and no itemised receipt.
Bills you for clearing a shared or public sewer that sits with Severn Trent, without checking the responsibility boundary first [2].
Uses chemical cleaners as the main fix, leaves chambers uncovered or ground unreinstated, or demands cash with no paperwork.
Quotes a repair or a dig without visiting, asking for photos, or lifting a chamber cover to see the run.
Will not put the scope, the staged prices and the start time in writing before lifting a tool.
Starts the job with no agreed ceiling price, then adds extra stages by phone once the chambers are open.
Leaves spoil, sludge or old pipework with you to get rid of, when disposal was always part of what you paid for.
