Checking a Portsmouth contractor before you book
Every contractor on this page was on the BESA Vent Hygiene Register when it was read on 20 September 2026. Membership lapses, and the register also records firms that have been suspended for non-compliance or removed altogether, so it is worth checking the register itself before you sign anything. Our national ranking of the sixteen dual-accredited contractors explains what the accreditations mean and what a verification report should contain.
Questions about duct cleaning in Portsmouth
How many accredited duct cleaning companies serve Portsmouth?
46 contractors on the BESA Vent Hygiene Register are registered within 100 miles of Portsmouth, and 5 of those hold accreditation in both TR19 categories. A further 11 accredited contractors say on their own websites that they work nationwide. The register was read on 20 September 2026.
Does a contractor have to be local to clean ventilation in Portsmouth?
No. Ventilation hygiene is planned compliance work on a schedule, not an emergency call-out, so contractors routinely travel for it and many of the larger firms work across the country. Distance matters for the cost of getting a team to site and for how quickly remedial work can be scheduled, which is why every distance on this page is shown.
What should a Portsmouth contractor give me when the work is finished?
A post-clean verification report with before and after evidence for each section of the system, the method used, and a certificate confirming the system was cleaned to the relevant TR19 specification. That document is what an insurer or a fire risk assessor asks to see. Photographs on their own are not evidence.
