Keep your boiler running safely, efficiently, and under warranty with an annual service by Gas Safe registered engineers. Covering Medway and all of Kent — landlord CP12 certificates also available.

Comprehensive inspection, cleaning, and testing of all key boiler components. We check everything from the burner and heat exchanger to the flue, seals, and condensate trap.
All major boiler manufacturers — Worcester Bosch, Vaillant, Baxi — require annual servicing by a Gas Safe engineer to maintain the warranty. We provide service documentation.
A dirty or poorly set-up boiler can consume 10–15% more gas. A service optimises combustion settings and cleans key components to restore peak efficiency.
A service catches worn parts, early-stage faults, and safety issues before they become expensive breakdowns — saving you money and preventing winter boiler failures.
We issue Gas Safety Certificates (CP12) for landlords in Medway and Kent. A legal requirement every 12 months — book in advance to ensure you're always compliant.
All our service engineers are fully Gas Safe registered. We carry our Gas Safe ID on every visit — ask to see it.
Your boiler works hard every day through autumn and winter. Like any mechanical system, it needs regular maintenance to stay safe, efficient, and reliable. An annual service is the single best thing you can do to protect your investment and avoid an inconvenient breakdown at the worst possible time.
Carbon monoxide is produced by a poorly maintained or faulty boiler. It is odourless and colourless — which makes annual safety checks critical. Our service includes a full combustion analysis to verify your boiler is burning gas cleanly and efficiently.
For homeowners who have a manufacturer warranty, annual servicing is not optional — it is required. Missing a year of servicing typically voids the warranty entirely. Our engineers provide full service documentation to keep your warranty records up to date.
UK law requires every landlord to have a Gas Safety check (CP12) carried out annually by a Gas Safe registered engineer on all gas appliances in rented properties. Failure to comply can result in significant fines and criminal prosecution.
Plumbing Boss provides CP12 Gas Safety Certificates to landlords across Medway and Kent. We can service multiple properties on the same day, issue certificates promptly, and set up annual reminders so you never let compliance lapse.
