7 Best Plumbers in Blackburn for 2026

Blackburn's housing stock is a real mix. You've got rows of Victorian and Edwardian terraces across areas like Bastwell and Billinge, semi-detached post-war builds spreading out towards Lammack and Revidge, and newer estates further out near Shadsworth. Older properties often come with original cast-iron soil pipes, gravity-fed hot water cylinders, and pipework that hasn't been touched in decades. Combination boilers have replaced most of those old systems now, but plenty of homes still run on conventional boiler setups with a separate tank in the loft, and those need a plumber who knows what they're doing. Hard water is a genuine issue across Lancashire, and limescale build-up in pipes, hot water cylinders, and shower units is something local plumbers deal with constantly. You'll also find that properties in the lower-lying parts of town occasionally have drainage issues when heavy rainfall hits, so it's worth finding someone familiar with the area rather than a tradesperson who's never worked this side of the M65.

The businesses on this page are drawn from third-party public business listings and ranked by review rating and review count, with a small lift given to those that have a working website and a listed phone number. Before any business appears, we check its homepage to confirm that plumbing is what it primarily offers. That step is what keeps unrelated trades off the page. Listings flagged as permanently closed are removed automatically, so you won't find businesses that have shut down. Where you see a Trust Verified badge next to a business, it's passed our full verification process, which covers trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. Visit our How We Verify page for the full list of checks involved. Businesses without that badge have not been independently verified by us, and you'll want to carry out those checks yourself before committing to a booking.

Before you pick up the phone, get at least two or three quotes. Prices for a standard boiler service in Blackburn typically run between £60 and £100, while a new combination boiler installation with labour usually sits somewhere between £1,500 and £2,800 depending on the make and complexity of the job. Always ask whether a plumber is Gas Safe registered before any gas work is carried out, and ask for the Gas Safe ID card number so you can verify it directly on the Gas Safe Register website. For any new boiler installation or gas appliance, you're legally entitled to a Building Regulations Completion Certificate. Check the plumber carries public liability insurance, and ask for it in writing if you're having anything significant done. For older homes, it's worth asking whether they've worked with lead or iron pipework before, since not everyone has.
