Gas Safety Certificate (CP12) in Hertford
From enquiry to certificate: Gas Safety Certificate (CP12) for landlords in Hertford, handled by professionals holding the registration the law requires, with pricing confirmed before you commit.
Straight answer
If you let a property with gas appliances in Hertford, the law requires a gas safety check every 12 months, carried out by a Gas Safe registered engineer. The record it produces — the CP12 — goes to your current tenants within 28 days, and to new tenants before they move in.
Booking
From enquiry to certificate
We're building coverage in Hertford through our national onboarding programme, and we won't pretend otherwise with a fake availability calendar. Send the property details and we'll confirm by email whether we can cover the job, and the price, before anything is committed.
Pricing
What a CP12 costs
Two identical adverts can hide very different jobs — one boiler versus four appliances, ground-floor flat versus awkward loft access. That's why we show a guidance range rather than a headline teaser price, and confirm the real figure for your property before you commit. Bundling the annual boiler service into the same visit typically works out cheaper than booking it separately.
The law
Your legal duty, in plain English
Legally, three things are required of you: a check of every appliance and flue at intervals of no more than 12 months, carried out by a Gas Safe registered engineer; a record of that check retained for at least two years; and copies to tenants — within 28 days for existing tenants, before move-in for new ones. The regulations apply UK-wide, and the HSE treats non-compliance as a criminal matter with unlimited fines available.
Landlords must have every gas appliance and flue they provide checked by a Gas Safe registered engineer at least every 12 months, keep the record for two years, give tenants a copy within 28 days of the check, and give new tenants a copy before they move in.
Equivalent annual duty applies in Northern Ireland; engineers must be Gas Safe registered.
Penalties stated are statutory maximums or court-set; East Herts Council is the local housing authority for Hertford.
Credentials
Who you're letting in
Gas work is one of the few trades where the register isn't optional: an engineer who isn't Gas Safe registered can't legally sign your record, full stop. We check registration and insurance before confirming any booking, and you can verify any engineer yourself on the public Gas Safe Register — ask to see the ID card, and check the back for the work categories it covers.

Letting in Hertford: the practical points
For landlords in Hertford, the practical points are the universal ones: annual check, Gas Safe engineer, tenant copies on time. Keep the record where you can produce it quickly — for your agent, your insurer, or East Herts Council if the property is licensed or ever inspected. Certificates that can't be found cause almost as much trouble as certificates that were never done.
The inspection
What the engineer actually checks
Expect the visit to run appliance by appliance. Tightness testing at the meter comes first, ruling out leaks anywhere in the pipework. Each appliance is then fired up and tested — burner pressure or heat input, safety devices, stability, ventilation to the room — and each flue is checked for pull and termination. Defects are graded by how dangerous they are, and only a Gas Safe registered engineer's signature makes the resulting record valid.
FAQ
Before you book: quick answers
Do the same gas rules apply in Scotland, Wales and Northern Ireland?
Yes — the Gas Safety (Installation and Use) Regulations 1998 apply UK-wide (Northern Ireland has parallel regulations to the same effect). The annual check, the 28-day tenant copy rule and Gas Safe registration requirements are consistent across all four nations.
What does the gas safety record actually include?
It lists each appliance and flue checked, the checks performed, defects found and action taken, the engineer's name, registration number and signature, the property and landlord details, and the date of the check.
Is a gas safety check the same as a boiler service?
No. The safety check confirms appliances are safe to use; a service is a maintenance clean and inspection of the boiler itself. Many landlords in Hertford book both together because the engineer is already on site, but only the safety check is a legal requirement.
Do I have to give tenants a copy of the gas safety record?
Yes. Existing tenants must receive a copy within 28 days of the check, and new tenants must get one before they move in. For rental periods under 28 days, displaying a copy in the property is acceptable.
What if an appliance fails the gas safety check?
The engineer records the defect and classifies how dangerous it is. Immediately dangerous appliances may be disconnected with your permission. You must have faults fixed by a Gas Safe engineer before the appliance is used again; the record itself lists the defects found.
