A Gas Safe registered engineer inspects and tests each appliance, the pipework and the flues, records the results, and issues the record for the landlord to keep and to give to tenants. ### Who it is for Private landlords with a single property, landlords with portfolios, letting and managing agents arranging compliance across multiple addresses, and HMO operators who need every appliance in the building recorded. ### When you need it Every twelve months, and before the start of any new tenancy. Existing tenants must be given a copy within 28 days of the inspection, and new tenants at the start of the tenancy, so it pays to schedule ahead of expiry rather than on the day. ### Why it needs a registered engineer This is a legal duty with criminal liability attached, and the appliances in a tenanted property are the ones you personally see least often. Tenants rarely report a gas fire that is sooting or a boiler making an unusual noise until it stops working. The annual inspection is how those conditions are found, and the record is how you demonstrate you met your obligations.

Our process ## How We Carry Out the Work, Step by Step - 1 ### Step 1: Booking around the tenant We arrange appointment slots that suit the tenant, coordinate with the agent where there is one, and confirm access arrangements before the day so visits are not wasted. - 2 ### Step 2: Full appliance inspection Every gas appliance in the property inspected: boiler, fire, cooker, hob: along with pipework, flues, ventilation and clearances. - 3 ### Step 3: Testing and analysis Tightness testing on the installation, working pressure and gas rate at each appliance, flue integrity checks and flue gas analysis with readings recorded. - 4 ### Step 4: Classification of any defects Anything found is classified as Immediately Dangerous, At Risk or Not to Current Standards, explained plainly, and quoted at a fixed price so you can authorise the repair immediately. - 5 ### Step 5: Records issued and diarised The CP12 is completed and emailed to landlord and agent the same day wherever possible, and we set an annual reminder so next year's inspection is booked before it lapses. What you get ## The Difference It Makes ### Compliance without chasing Annual reminders and pre-booked slots mean the record is renewed before expiry rather than after a prompt from an agent. ### Tenant-friendly access Appointment slots arranged around tenants, which is what actually determines whether an inspection happens on the first visit. ### Same-day digital records Digital copies emailed to landlord and agent wherever possible, so the compliance file is complete immediately. ### One visit for the whole property Every gas appliance inspected together, and servicing or repairs carried out in the same appointment where possible. ### Repairs quoted on the spot Any defect comes with a fixed price so you can authorise the fix without arranging another engineer. ### Portfolio scheduling Multiple properties grouped into planned visits, with consistent documentation across the portfolio. In detail ## CP12 Inspections, Portfolios and HMOs The landlord's duty covers appliances and flues the landlord owns and provides. Where a tenant has brought their own gas appliance, the appliance itself is not the landlord's, but the installation and the flue serving it remain within scope, and in practice it is worth having the whole picture recorded so there is no ambiguity later. We identify every gas appliance on site at the inspection and record what was and was not within scope, so the file is unambiguous. HMOs and multi-occupancy buildings need more care. There may be a communal boiler plus individual appliances, several kitchens with separate cookers and hobs, and access to arrange with multiple occupants. We plan those inspections as a single coordinated visit wherever access allows, and record each appliance individually so the documentation shows exactly what was inspected in which part of the building. Timing and record-keeping are where landlords most often come unstuck. The record lasts twelve months from inspection. Existing tenants must receive a copy within 28 days, and new tenants at the start of the tenancy. Where an inspection is done slightly early, the renewal date can be maintained rather than drifting forward each year. We keep your inspection dates and prompt you ahead of expiry, which removes the single most common cause of an accidental breach. Where a defect is found, speed matters more than in an owner-occupied property, because a tenant is living with it. We classify the fault, explain it to you and to the tenant in plain terms, and give you a fixed repair price straight away. Where an appliance has to be turned off, we make sure the tenant understands what is affected and what happens next, and we prioritise getting them back to normal, including immediate boiler installation from £1,299 fully fitted where the appliance is beyond repair. ### Residential and commercial properties Our landlord work covers houses, flats, HMOs and mixed portfolios across Liverpool, Knowsley, Halton and St Helens. Where a property has commercial catering or plant appliances, tell us at booking so we can confirm scope before attending. ### Variations of this service - Single property CP12 Annual inspection and record for one rented property, with copies for tenant and agent. - Portfolio and agent scheduling Grouped visits across multiple addresses with consistent digital documentation and renewal tracking. - HMO and multi-occupancy inspections Communal and individual appliances recorded separately, with coordinated access across occupants. - CP12 plus service in one visit Inspection and annual boiler service combined, so a single access arrangement covers both. ### Materials, parts and equipment - Calibrated flue gas analyser and manometer - Gas tightness testing equipment - Digital CP12 records emailed to landlord, tenant and agent - Warning and labelling materials for at-risk appliances - Annual renewal reminders tied to your inspection dates - Gas Safe registration no. 576059, licence no. 3715984 Questions ## Landlord Certificate: Frequently Asked Questions How much does a landlord gas safety certificate cost?We give you a fixed price when you ring, based on the number of gas appliances in the property. Portfolios are quoted as a scheduled programme, which usually works out better than booking properties one at a time. How long does a CP12 inspection take?Usually between half an hour and an hour depending on how many appliances there are. Combining it with a boiler service in the same visit adds time but saves a second access arrangement. How often is a CP12 legally required?Every twelve months, and before the start of a new tenancy. Existing tenants must get a copy within 28 days of the inspection and new tenants at the start of the tenancy. How quickly do I get the paperwork?Same day wherever possible, emailed as a digital record to you and your managing agent. We also diarise the renewal and prompt you before it expires. What if an appliance fails?We classify the defect, explain it to you and the tenant, and quote a fixed price to repair it immediately. Where an appliance is beyond repair, new boilers start from £1,299 fully fitted with immediate installation available. Who arranges access with the tenant?We do, or your agent does: whichever you prefer. We offer slots that suit tenants because that is what makes the first visit successful rather than a wasted trip. Do tenants' own gas appliances need certifying?A tenant's own appliance is not the landlord's responsibility, but the installation and flue serving it are within scope. We record clearly what was inspected and what was not, so your file is unambiguous. Do you cover HMOs and portfolios across Merseyside?Yes: single lets, HMOs and portfolios across Liverpool, Knowsley, Halton and St Helens. We answer the phone seven days a week, 8:30am to 5:30pm, and we tell you the same day whether we can get to you. Still not sure? Send us the details or ring 07523 738285.
