Fire Alarm Installation & Servicing in Penwith

Overview

A working fire alarm is one of the most basic safety requirements in any property — and one that's frequently underestimated until something goes wrong. For landlords and holiday let owners, it's also a legal compliance issue. I install mains-wired interlinked smoke, heat, and carbon monoxide detection systems across Penwith to BS 5839-6, issue the necessary certification, and carry out annual servicing where required. Whether it's a straightforward domestic install, a full landlord-compliance package, or a system that needs upgrading from standalone battery units to an interlinked mains system, I can handle it.

What's involved

Assessment and system design

Every property is different. I'll work out the right number and type of detectors for the layout — smoke alarms in hallways and landing areas, heat detectors in kitchens, CO detectors where gas appliances are present. For larger properties or HMOs the system design matters more; I'll walk through BS 5839-6 recommendations with you before quoting.

Installation and wiring

Mains-wired interlinked alarms are wired from the consumer unit to a dedicated circuit. Each detector communicates with the others so that one alarm triggers all of them simultaneously — the critical requirement for any rented or let property. Battery-only standalone alarms don't meet this standard for most landlord situations. I handle all cable runs, detector positioning, and consumer unit connections.

Testing, certification, and handover

Once installed, the full system is tested and I issue a BS 5839-6 installation certificate. For landlord and holiday let situations, this is the documentation your insurer and letting agent will want to see. I'll also walk you through the testing procedure so you can carry out the weekly alarm test yourself between annual service visits.

Typical Costs

from £200From £200 (2-detector mains-wired system if full re-wire)

Price depends on the number of detectors, cable runs required, and whether a new consumer unit circuit is needed. Larger properties, HMOs, and holiday lets with more complex layouts are quoted individually. Annual servicing recommended.

Common Questions

What grade of fire alarm system do I need for a rental property?

For most domestic rental properties in England, the minimum requirement under the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 is a smoke alarm on every floor and a CO detector in any room with a solid fuel appliance. In practice, mains-wired interlinked Grade D alarms (to BS 5839-6) are the accepted standard for demonstrating compliance. HMOs (houses in multiple occupation) have stricter requirements and usually need a more comprehensive system — the exact specification depends on the property and the number of occupants. If you're unsure what your property needs, I'll work through it with you before quoting.

Do you offer free quotes?

Yes, quotes are free with no obligation. Call or WhatsApp and we can discuss the job - for anything straightforward I can usually give a price over the phone, and for larger jobs I'll arrange a site visit.

Do holiday lets in Cornwall need a fire alarm system?

Yes. Holiday let properties are treated differently from standard residential lets — insurers and booking platforms increasingly require evidence of a working, compliant fire detection system. Most holiday let insurers will ask for a mains-wired interlinked system rather than battery-only standalone alarms. For properties listed on Airbnb, Sykes Cottages, or through a local letting agent, a BS 5839-6 installation certificate from a registered electrician is the cleanest way to demonstrate compliance. Annual servicing produces a service record that also helps at insurance renewal.

What area do you cover?

I cover Penzance, St Ives, Hayle, Marazion, Newlyn, St Just, Camborne, and the wider Penwith peninsula. If you're unsure whether you're in range, just call and ask - I'm happy to travel for the right job.

What is the difference between a smoke alarm and a heat detector, and do I need both?

Smoke alarms detect airborne particles produced by a fire and are the right choice for hallways, landings, living rooms, and bedrooms. They're the primary life-safety device. Heat detectors respond to a rise in temperature rather than smoke, and are the correct choice for kitchens — where cooking fumes would cause frequent false alarms from a standard smoke alarm. For a typical domestic property, the right setup is smoke alarms on each floor and a heat detector in the kitchen. I'll confirm the exact combination for your layout during the assessment.

Are you NAPIT registered?

Yes, I'm NAPIT registered - member number 66376. You can verify this on the NAPIT website by searching for Cornovii Electrical. NAPIT registration means I'm assessed annually against industry standards and can self-certify notifiable electrical work, including consumer unit upgrades and new circuits.

How often should fire alarms be serviced?

Mains-wired interlinked systems should be serviced annually by a qualified electrician. The service involves testing each detector individually, checking the interconnect function (so all alarms sound when one is triggered), inspecting wiring connections, and issuing a service record. In between annual visits, you should test the system yourself weekly using the test button on the main alarm — this takes about 30 seconds and confirms the battery backup is working. I'll walk you through this at installation. Weekly testing is a requirement under most landlord and holiday let insurance policies.

Are you VAT registered?

Not currently, which means there's no VAT to add on top of my prices. This may change in the future, but any change would be communicated clearly before work is quoted or carried out.

Can I upgrade my existing battery alarms to a mains-wired interlinked system?

Yes, and it's a straightforward upgrade for most properties. The existing battery-only alarms are removed and replaced with mains-wired detectors connected back to the consumer unit on a dedicated circuit. The wiring is surface-run where possible to minimise disruption, though on older properties we can discuss concealed runs. Most upgrades in a standard three-bedroom house can be completed in a day. You'll receive a BS 5839-6 installation certificate on completion.
