About us

Bristol

An independent

Bristol drainage company

Not a franchise, not a call centre, and not a national brand routing your job to whoever answers. Flow Sure Drains is a small Bristol firm run by Anthony Lord, and the person who quotes you is generally the person who turns up.

How this started

Why the prices are on the website

Most drainage companies won’t tell you what anything costs until an engineer is standing in your garden. We publish the lot, and that decision explains most of how this business works.

The reason is straightforward. Drains block at bad times — a Sunday evening, the morning of a party, the week you exchange contracts. People ring in a mild panic, and an industry that prices opaquely does very well out of that panic. Call-out fees that appear on the invoice but not the quote. Hourly rates that stretch. Weekend surcharges of fifty per cent on a job that isn’t harder for being on a Saturday.

None of that is illegal and plenty of firms do it. It just isn’t the business we wanted to run, largely because we’d have to keep doing it to the same few thousand households for years.

“If I’ve quoted you a price and then the invoice is bigger, I haven’t earned anything. I’ve just borrowed a customer from whoever gets them next.”

— Anthony Lord, Flow Sure Drains

What that means in practice

Every price we charge is on the cost guide. There’s no call-out fee, no distance charge, and the same figure applies at 8pm on a Sunday as at 10am on a Tuesday. The price is fixed on site before anything starts, and if you’d rather not go ahead once you’ve heard it, there’s nothing to pay and we leave.

And the part that costs us work

The advice section exists because the same questions come up on doorsteps every week — usually after someone has already been quoted for work that was never theirs to pay for.

So we wrote it down. That a slow kitchen sink will probably clear with hot water and a plunger. That if your neighbours have the same problem at the same time, the drain is likely shared and Wessex Water’s responsibility rather than yours. That a survey isn’t worth paying for on a first-time blockage that cleared easily.

 Each of those loses us a job. It also means that when you do need someone, you already know what you’re getting — and we’d rather have that than one more invoice.

What we're often asked to do

Anthony Lord

Owner, Flow Sure Drains

Anthony has been working on Bristol’s drains for years, and has run Flow Sure Drains since 2010. He still does the work — on most jobs, the person who gave you the price is the person who arrives.

He writes the advice guides on this site, including who’s responsible for a blocked drain and what drain unblocking actually costs. All of it comes from jobs rather than from research.

He knows Bristol’s pipework specifically, which matters more than it sounds. Victorian clay in Redland fails differently from Georgian runs under Clifton, which behave nothing like the interwar semis and soakaways out in Fishponds. Knowing which you’ve got before lifting a cover saves a great deal of everyone’s time.

How we work

Four things we don't budge on

These aren’t marketing lines. They’re the rules the business runs on, and they’re the reason the pricing looks the way it does.

ONE

The price is agreed before we start

One fixed figure, on site, before any work begins. Not an estimate, not a starting point, and not something that grows once the van is unpacked.

If you’d rather not proceed, there’s nothing to pay and we leave. That has to be a real option or the promise means nothing.

TWO

We find the fault before we clear it

Rodding blind pushes a blockage further down the pipe and calls it fixed. It works for about a fortnight.

We establish where the problem actually is first, then clear it, then flow test while we’re still there. A blockage moved is not a blockage cleared.

THREE

We'll tell you if it isn't your bill

If a drain serves more than one property it’s very likely a shared lateral, and since 2011 that’s generally the water company’s responsibility rather than yours. They attend free.

We check what the run serves before anyone pays for anything. It costs us jobs and it’s the right way round.

FOUR

We don't sell surveys nobody needs

A camera survey is genuinely valuable when a drain keeps blocking, or before you buy a house. On a one-off blockage that cleared easily, it usually isn’t.

We’ll say so. A survey recommended on every job is a sales process, not a diagnosis.

Straight about the limits

What we don't do

A shorter list than the services page, and more useful. Knowing what a company won’t take on tells you more than knowing what it will.

If it's not us you need

We’ll usually know someone local who does that work, and we’d rather point you at them than take a job we can’t finish properly.

Ring and describe it. Working out whose problem it is takes about two minutes and costs nothing.

Tony at Flow Shure is fast to act on a drain issue and came to my support to fix a problem not just once but a second time at no extra expense 6 months later at short notice. He has provided the best service I've ever had from a tradesmen.

About the company

What people ask us

Are you a franchise or a national company?

Neither. Flow Sure Drains is an independent Bristol firm. When you ring, you’re speaking to us rather than to a national call centre that sells the job on to whoever is nearest.

That’s why the person who quotes you is generally the person who turns up.

One of our team. It’s small enough that you’ll recognise whoever arrives if you’ve used us before, and small enough that a bad job would be traced straight back to us.

Yes — INSURANCE public liability, and we’ll send the certificate on request before any work starts.

Worth asking any drainage company for this. One that has it will send it within the hour.

Flow Sure Drains has run since 2010, and has been listed on Checkatrade for 10 years with reviews you can read in full. There are also 126 reviews on Google, unedited — we don’t get to choose which ones show.

Because you shouldn’t have to ring three companies to find out what a job costs, and because an industry that prices opaquely does well out of people who are panicking.

Every figure is on the cost guide. The price is fixed on site before work starts, and there’s nothing to pay if you decide against it.

Regularly. A slow kitchen sink will often clear with very hot water and a plunger. A drain shared with your neighbours is usually Wessex Water’s responsibility and they attend free. A survey isn’t worth paying for on a first-time blockage that cleared easily.

Each of those costs us a job. It’s still the right answer, and it’s why the advice section exists.

Yes — we invoice, work to purchase orders, attend outside trading hours at no premium, and provide a written report after every visit. Commercial drainage covers how that works.

Ring us. We flow test or re-survey before leaving specifically so that doesn’t happen, but if the same fault returns we’d rather hear about it than read about it in a review.

Give us a ring

Tell us your postcode and what the drain is doing. We’ll tell you what it sounds like, roughly what it’ll cost, and when we can be there — and if the answer is that you don’t need us, that’s what you’ll get.
