Service Overview
Owner-led by Pierre Codarin from Southend-on-Sea. Single point of contact from first call to final invoice.
What it is
A CP12 (Landlord Gas Safety Record) is a legally-required annual inspection of every gas appliance, flue and pipework in a rented property, signed off by a Gas Safe-registered engineer. Avanza books, attends, inspects, and emails the signed certificate the same day.
Who it's for
Private landlords, letting agents and HMO operators across Essex. From a single buy-to-let flat to a 40-property portfolio — we scale.
When you need it
Every 12 months, ahead of the expiry date on the current certificate. We diary the renewal so you don't have to remember. Also required before any new tenancy starts and within 28 days of any new gas appliance being installed.
Why hire a professional
Under the Gas Safety (Installation and Use) Regulations 1998, landlords are legally responsible for the safety of gas appliances in let properties. A missing or expired CP12 is a criminal offence with unlimited fines and, in the worst cases, imprisonment. It also voids landlord insurance.
The Real Cost Of Getting This Wrong
A missed CP12 is not a paperwork issue — it's a legal, financial and safety issue, and the consequences land squarely on the landlord.
Our Process
Call or email with property address, tenant contact details, and number of gas appliances. We confirm an inspection slot — often within 48 hours.
We coordinate access directly with the tenant where instructed — no toing-and-froing through you.
Typically 45–75 minutes per property. Every gas appliance, flue, pipework and emergency control inspected against current Gas Safety Regulations.
Signed CP12 emailed to landlord, letting agent and tenant on the day of inspection. Photographs of any defects included.
We diary the renewal date and email you 30 days before expiry. One less thing to track.
Benefits
Inspection completed and CP12 emailed the same day — no waiting for paperwork.
We talk to the tenant directly to book access — you don't have to be the middleman.
Block bookings for letting agents and portfolio landlords get priority scheduling.
Automatic 30-day reminder before expiry — never miss a renewal.
Anything that fails inspection gets a free written quote on the day, price-fixed for 14 days — no separate visit needed.
Gas Safe registered and fully insured. Certificates available on request.
Inside The Detail
These are the details cheaper installers skip — and the reason their work fails inside two years.

Full Service Area ListEvery gas appliance (boiler, hob, oven, gas fire) is checked for: tightness of the gas pipework, correct flue operation, satisfactory combustion (CO/CO₂ ratio), adequate ventilation, safe location, and effective operation of safety devices. Each appliance is recorded individually with a pass/fail and any defects noted. The certificate also notes the location of the emergency control valve.
Houses in Multiple Occupation (HMOs) require the same annual CP12 as single-let properties, plus additional checks where shared appliances are present in communal areas or shared bathrooms. We work with HMO operators across Essex and coordinate inspections to minimise tenant disruption — typically completing a 6-bed HMO in 90 minutes.
A copy of the current CP12 must be issued to a new tenant before they take occupation. If a new gas appliance is installed during a tenancy, a fresh inspection is required within 28 days. Failing either obligation invalidates any future Section 21 notice. We can fast-track a CP12 for pre-tenancy turnover — often within 24 hours.
If any appliance fails the inspection — typically due to combustion, ventilation or flue issues — we'll quote the repair in writing on site. Where the issue is dangerous (CO leak, gas leak, unsafe flue), the appliance is isolated and tagged immediately, and a follow-up repair visit booked within 24–48 hours. Re-inspection and a fresh certificate issued on successful repair.
Questions
Cost, timeline, guarantees, lifespan, emergency cover — answered without the sales speak.
Ask YoursEvery CP12 is priced from the property and appliance count after a quick free call — we don't list a 'from' figure because the right number depends on the gas appliances in the property and access. Quotes are free and price-fixed for 14 days; portfolio landlords get priority scheduling.
Single-appliance property 30–45 minutes. Boiler + hob property 45–75 minutes. HMOs 60–120 minutes depending on size. Certificate emailed the same day.
