What your appointment day looks like
- Booking
Confirm your appointment window
Tell us your boiler's make and model and where it's located, so the right checklist and parts knowledge are ready.
- On site
Full checklist, not a shortcut
Internal components, flue, ventilation, combustion and safety devices — the same checklist every visit, every boiler.
- Wrap-up
Written record handed over
You get a written service record or certificate before the engineer leaves, not emailed days later.
- After the visit
Renewal reminder set
Your next service or CP12 renewal date is noted, so compliance doesn't depend on you remembering.
Before your engineer arrives
Have your boiler's details ready
Make and model, and roughly how old it is — this helps us bring the right parts knowledge to the visit.
Note anything unusual
Strange noises, pressure that keeps dropping, or rooms that heat unevenly — mention these when you book.
Find your last service record
If you have one, having it to hand helps the engineer see what's changed since the last visit.
Ask about combining visits
Landlords can often combine an annual service with a Gas Safety Certificate inspection in one call-out.
Built for compliance that can't slip
Fully Gas Safe registered
Every visit is carried out by a fully Gas Safe registered engineer — the legal minimum for any gas work, not an optional credential.
A written record every time
You leave every visit with a written service record or certificate — the paperwork your warranty and your tenants actually need.
Renewal reminders, not guesswork
Service and CP12 renewal dates are tracked so cover doesn't lapse by accident between one year and the next.
Quoted before we start
Boiler make, model and access all affect the price — we confirm it before booking, not after the visit.

tested every visit
A test that backs up the paperwork
We don't call a service done because the boiler switched on. Combustion analysis and safety device testing confirm it's actually running safely.
- Combustion analysis — Confirms the boiler is burning gas efficiently and safely, not just running.
- Safety device testing — The components that shut the boiler down if a fault develops are tested on every visit.
- Whole-appliance CP12 checks — Every gas appliance, fitting and flue covered by your landlord obligations, inspected and certified.
- System pressure & controls — Radiators, thermostats and system pressure checked as part of a wider health check.

Common questions about boiler servicing
How often should my boiler be serviced?
Once a year, in almost all cases — this is the standard manufacturer recommendation and the usual condition attached to a boiler warranty. Booking before the heating season starts avoids the autumn rush.
Do you offer landlord Gas Safety Certificates (CP12)?
Yes. We inspect every gas appliance covered by your landlord obligations and issue the certificate, with a reminder set ahead of the 12-month renewal.
Are your engineers Gas Safe registered?
Yes — fully Gas Safe registered, which is the legal requirement for anyone working on gas appliances in the UK. Ask to see an engineer's ID card on any visit, from us or anyone else.
Can I combine a boiler service with a Gas Safety Certificate?
Yes — many landlords combine both in a single visit, since the certificate inspection covers the boiler anyway. It saves arranging a second appointment.
What's included in a service plan?
Plans range from 'annual service only' to 'service plus call-out cover'. We explain exactly what each tier includes before you choose, so there's no ambiguity about what's covered.
How much does a boiler service cost?
It depends on the boiler's make, model and how accessible it is. We confirm a quote before booking rather than applying a flat rate to every home — see our pricing page for typical UK market ranges.
What areas of London do you cover?
We cover all London boroughs. Our network of engineers is positioned to reach any postcode in Greater London for scheduled servicing and compliance visits.
Do you service commercial boilers?
Yes — offices, restaurants and managed buildings, scheduled around business hours where possible, with compliance paperwork suited to a facilities management file.
