[Request an Estimate](/contact-us) [07360 538643](tel:07360538643) Site survey arranged to suit you, written quote the same day, fully certified. 15+ years serving the CF postcode Years serving 7+ Postcodes covered 4-hour Response window 25 min Drive time Local relevance ## Why we know Cardiff properly Cardiff is the busiest patch on our books. We work daily across Cathays and Roath student HMOs, Cardiff Bay apartment blocks, the Pontcanna and Canton conversion market, and the commercial corridor running through the city centre and Capital Quarter. Most of our Cardiff work comes from licensing-driven HMO upgrades, post-purchase compliance audits for new landlords, and reactive servicing contracts for letting agents managing 20+ doors. Because we are 25 minutes up the A470 in Bargoed, our engineers are on site in Cardiff faster than most providers based in the West Country or Bristol, and we know which Cardiff Council licensing officer covers which ward, which speeds up sign-off considerably. ### Property types we cover The Cardiff stock we cover is mixed and we adjust grade and category accordingly. Victorian and Edwardian terraces in Cathays, Roath and Canton, typically 4–6 bedroom HMOs requiring Grade A LD2 or LD1 systems with sounders in every sleeping room. Newer apartment blocks in Cardiff Bay, Capital Quarter and the John Street/Tyndall Street corridor, addressable panels with interface to AOVs, sprinklers and door retainers. Commercial premises across the city centre, Splott and Leckwith industrial estates, conventional or addressable panels sized to fire risk assessment. We also handle plenty of HMO conversions in Heath, Adamsdown and Grangetown where the existing wiring needs a full rip-out rather than an extension. ### What Cardiff actually needs Three jobs dominate Cardiff: Grade A LD2 installs for licensable HMOs ahead of inspection, six-monthly servicing for portfolios already certified, and emergency call-outs for false-alarm-prone systems in student lets. We also see steady demand for emergency lighting upgrades on conversions where the original 1990s install no longer meets BS 5266, EICR certificates for landlord licence renewals, and PAT testing on furnished lets. Most enquiries arrive 2–6 weeks before a Cardiff Council HMO inspection, we work to that deadline, in writing, and we attend the inspection with the landlord if requested. ### Response into Cardiff Reactive call-outs in Cardiff are typically attended within 4 hours for contract clients and same-day for portfolio accounts. Our vans run a CF–NP–RCT circuit daily, so unless the engineer is mid-commission on another job, you are not waiting until tomorrow. Out-of-hours cover is available on annual maintenance contracts, sounders ringing at 2am in a 6-bed student let is the kind of thing we are set up to handle properly, not just silence and reset. ### Track record here 180+ Cardiff properties certified in the last 12 months. 15+ years serving the CF postcode. Postcodes CF10, CF11, CF14, CF23, CF24, CF3, CF5. 25 minutes from our Bargoed HQ via the A470.

View service ](/services/fire-extinguishers) Why us in Cardiff ## Concrete reasons, not slogans ### 180+ Cardiff properties last year From single HMOs in Cathays to 40-door portfolios across CF14 and CF23, we have a reference site within a postcode of yours. ### Same-day response inside the CF postcode Vans pass through Cardiff every working day. Contract clients get a 4-hour reactive SLA in writing, not a vague 'we will try'. ### Cardiff Council licensing fluent We know which evidence the HMO licensing team accepts on first submission and which formats trigger a re-inspection. ### Local supply chain Hochiki, Apollo and Aico parts on the van, most Cardiff faults fixed first visit, no two-day wait for a courier. Cardiff-specific challenges ## Problems we solve here that generic providers miss ### Victorian terrace cabling routes Cathays and Roath HMOs almost always need surface-clipped cable in lath-and-plaster ceilings. We use white LSF cable on PVC clips, never trunking, so the install passes both BS 5839 and a letting-agent visual check. ### False alarms in student lets Kitchens too close to detectors, vape near sounder bases, and old ionisation heads cause repeat call-outs. We re-zone, swap heads to multi-criteria, and add heat detection in kitchens to cut activations by 60–80%. ### Cardiff Bay leasehold complexity Apartment blocks need landlord-side panel work coordinated with the management company and AOV/sprinkler interfaces. We liaise directly with the block manager so leaseholders are not stuck in the middle. ### HMO licensing deadlines Cardiff's selective and additional licensing schemes don't wait. A 6-week lead time is realistic; anything tighter means we work weekends, and we say so in writing before you commit. Our process ## Same structured process on every Cardiff job 1. Step 1 ### Site Survey On-site survey at your Cardiff property to confirm grade, category and scope. 2.
