Most people picture Gas Safety Certificates as a quick look at the boiler. Once an engineer's inside a Thamesmead property, it's a far bigger job: every gas appliance, every flue, the ventilation around them and the pipework joining it all gets tested and recorded.
In Short
- Why a CP12 covers every gas appliance, not the boiler alone
- Our own Gas Safe engineers, employed directly and based locally
- How a same-day inspection can often be fitted in
- The fixed order every visit follows, from ID check to record
- What happens next if an appliance fails the inspection
Heating Services Ltd is Gas Safe registered and has worked in the area since 2008, using our own engineers rather than subcontractors. The same local team also handles water leak detection in Thamesmead, so anything found during an inspection stays with people who already know the property.

Gas Safety Certificate Overview
A gas safety certificate is the record every landlord needs for a rented home with gas. It's usually called a CP12, or a Landlord Gas Safety Record. It shows a Gas Safe registered engineer has checked the appliances, the flues and the pipework. And it's valid for 12 months, then it needs doing again.
We've been in the trade since 2008. Heating Services Ltd issues certificates across Thamesmead for landlords, letting agents and business premises, hotels and hospitality sites included. You'll get a clear written record and a plain explanation of anything we found. No surprises.
It isn't only for landlords. Homeowners can book the same check when they're buying, selling or uneasy about an older boiler or gas fire. Same visit. Same standard.

Gas Safe Registered Engineers in Thamesmead
Every certificate we issue is signed off by one of our own Gas Safe registered engineers. They're employed by us, not subcontracted, and they're locally based. David heads the team and brings over 21 years in the trade. But he isn't the one who turns up to every job, and he doesn't need to be.
That ID card matters. The Gas Safe Register is the official list of businesses legally allowed to carry out gas work. Our engineers will show you theirs at the door, and you're welcome to check it.
When a reading looks wrong, we don't guess. Our engineers work through it by method: a tightness test on the pipework, a flue check, a combustion reading. It's slower than a glance, and it's the only way a certificate means anything.
We handle gas safety certificates in Thamesmead and unvented cylinders in Thamesmead too. So the boiler side and the hot water side stay with one team that's already seen your system.

Areas Covered and Response Times
Across Thamesmead
We cover the whole of Thamesmead, in areas like SE28 and SE2. If you're after a gas safe engineer close to home in Thamesmead, ring us and we'll book the inspection. Flat, maisonette or house, it's the same inspection: every appliance, every flue, the pipework between them.
Beyond the Town
Our engineers work across Surrey, London and the South East. That spread is what keeps response times short. Nobody's driving in from the far side of the county to reach you, so you won't be waiting on one person's diary.
Hotels and Business Premises
We've a specialism in hotels and hospitality premises. Kitchens with several gas appliances, plant rooms and guest areas all need checking without stopping the business. We'll plan the visit around your service times, so it's done with the least disruption.

Booking and Same-Day Availability
Booking's simple. Tell us the address, how many gas appliances there are and when the property's accessible. We'll confirm the visit, and the engineer arrives with what's needed to test and certify.
Has the certificate run out sooner than you'd planned? We can often fit the inspection in the same day, because our engineers are spread across the area. That's the benefit of a local team rather than one van.
Every visit runs in the same order, so you'll always know where it's up to:
- The engineer arrives, shows their Gas Safe ID and confirms which appliances are on the record.
- Each appliance is tested in turn: boiler, cooker, hob, gas fire.
- Flues and ventilation are checked, and combustion is measured where it's needed.
- The pipework gets a tightness test to confirm there's no gas escaping.
- The record is written up and talked through with you before the engineer leaves.
- If anything fails, you're given a clear written quote for the repair.
The engineer who inspects is the one who explains the result. If something needs fixing, the same team quotes it, does it and retests it. You won't be passed along, and you won't be left chasing a certificate.

Landlord Legal Requirements and What the Inspection Covers
Landlords must have every gas appliance, fitting and flue in a rented home checked every 12 months. Existing tenants need a copy of the record within 28 days of the check. New tenants need one before they move in. It's a legal duty, and it's one you can't let slide.
Our gas safety certificate services are built around that yearly cycle. So the renewal doesn't creep up on you, and the tenant handover's covered.
Appliances, Flues and Ventilation
Every gas appliance on the property goes on the record. We check that it's burning correctly, that the flue's clearing fumes safely and that there's enough ventilation. Each additional appliance is tested and listed in its own right, so nothing's missed.
Pipework and the Tightness Test
The pipework is tested as a whole. A tightness test shows whether the system's holding pressure or losing gas somewhere along the run. It's the part people don't see, and it's often where problems hide.
If Something Fails
If an appliance isn't safe, we'll tell you plainly and make it safe before we leave. You'll get a written quote for the repair. Where a boiler's beyond sensible repair, we'll quote a boiler replacement instead, with installations backed by a guarantee of up to 10 years. Once the work's done, we retest and issue the certificate. That's the whole job, start to finish, with one firm.
From gas safety certificates in Thamesmead to every other gas safe job, we cover the whole area. Get in touch, tell us how many appliances you've got, and we'll get an engineer booked in.
