Our drainage services
FS Group provides drainage services in London for homes, businesses, and the maintenance companies that keep them running.
If any of these sound familiar, our drainage engineers have seen it before and know how to sort it.
Blocked external drains
Outside drains back up fast once leaves, grease, or debris start collecting at the gully. We clear the blockage, flush the system, and check for anything further down the line that could cause a repeat.
If your drain keeps blocking in the same spot, something deeper is usually causing it. We run a CCTV survey to find the root cause, then fix it properly so you stop paying for the same job twice.
Bad smells from drains, gullies, or manholes usually point to a trapped blockage, a dry trap, or a damaged pipe. We track down the source, clear what needs clearing, and stop the smell coming back.
Water taking too long to drain points to a build-up in the pipework, usually grease, hair, or soap scum. We clear the pipe quickly and check the rest of the run so the problem doesn't spread to other fittings.
A collapsed pipe means the system has failed completely and needs proper repair. We locate the damage with CCTV, then fix it using relining where possible or excavation if the pipe is too far gone.
Our team are on hand to assist with external drain blockages 24/7. If you have an outside blocked drain or an overflowing external drain then get in touch, our team of expert drainage engineers have the tools to clear external drain blockages quickly and efficiently. We are experts in restoring flow and getting you back up and running

How quickly can you get a drainage engineer out to me?

How much does it cost to clear a blocked drain?
Most blocked drains in London cost between £55 and £190 to clear, depending on the method and severity. Simple rodding sits at the lower end, high-pressure jetting at the higher end. Out-of-hours call-outs add a premium. Call us for an accurate quote over the phone.
How long does it take to clear a blocked drain?
Most blockages are cleared within one to two hours. Stubborn blockages, root ingress, or jobs needing a CCTV survey can take longer. Our engineers diagnose on arrival and give you a realistic timeframe before starting any work, so there are no surprises.
Will I get the same price quoted over the phone?
In most cases, yes. We give honest quotes over the phone based on the problem you describe. If our engineer arrives and finds something different on-site, like a collapsed pipe instead of a blockage, we'll talk through any price change before starting.
Do you charge a call-out fee for drainage services in London?
No, we don't charge a separate call-out fee for standard appointments. Our quote covers the visit, diagnosis, and the work. For emergency or out-of-hours call-outs, the rate is higher, but you'll always know the cost before we start. No hidden fees, ever.
Can you clear a blocked drain without digging up the garden?
Yes, in most cases. High-pressure jetting, rodding, and drain relining all work without excavation. We only dig if the pipe is fully collapsed or unreachable any other way, which is rare. CCTV surveys help us confirm the right method before any work starts.
Do you handle drainage work for commercial contracts?
Yes. We work with facilities managers, property managers, housing associations, and national maintenance contracts. Priority Account holders get same-day response, dedicated points of contact, and full compliance paperwork handled in-house. Multi-site coverage is standard across London and the South East.
What happens if the blockage comes back after you've cleared it?
Our drainage work is backed by a 6-month workmanship guarantee. If the same blockage returns within that window, we come back and sort it. If a CCTV survey reveals a deeper structural problem, like root ingress or pipe damage, we'll quote separately for that fix.
Do you work weekends and bank holidays?
Yes, we operate 24/7, every day of the year, including weekends and bank holidays. The two-hour emergency response applies at any time of day or night. Out-of-hours call-outs do carry a slightly higher rate, which we'll confirm with you on the call before dispatching.
What areas do you cover for drainage services in London?
We cover all of London, including all boroughs, plus Essex, Kent, and Hertfordshire. That includes North, South, East, and West London, the City, and surrounding commuter towns. If you're unsure whether you're in our coverage area, just give us a call and we'll confirm.
