HEATING POINTERS
Worth knowing before you plan the work, set a budget and hire a Heating Engineer.
THE PROCESS EXPLAINED
A combi heats water on demand with no tank or cylinder, suits smaller properties with one bathroom. A system boiler uses a hot water cylinder but no cold water tank, better where several taps might run at once. A conventional (regular) boiler uses both a tank and cylinder, common in older or larger properties, or where mains pressure is poor.
THE PROCESS EXPLAINED
An annual service checks for gas leaks, correct combustion, and general safety, and most manufacturer warranties require it to stay valid. It's also when a heating engineer is most likely to catch a developing fault — a failing part or a a pressure issue — before it causes a breakdown, particularly in winter when boilers are used hardest.
REGULATIONS & SAFETY
Every Gas Safe registered engineer has an ID card with their registration number and the specific categories of gas work they're licensed for — ask to see it, and you can also check a registration number directly on the Gas Safe Register website before booking.
THE PROCESS EXPLAINED
A frozen condensate pipe (the small plastic pipe draining from a condensing boiler, often outside) is one of the most common winter boiler breakdowns — it causes the boiler to shut down as a safety measure. Pouring warm (not boiling) water over the pipe to thaw it, if safely accessible, sometimes fixes this without a call-out.
UNDERSTANDING THE JOB
Older properties often have narrower pipework, no cavity wall insulation, and sometimes a heating system not originally designed for full central heating throughout — all of which affect boiler sizing and radiator choice. A heating engineer working on a period property will usually assess the whole system, not just swap the boiler in isolation.
RULES & STANDARDS
A new boiler installation legally requires a certificate under the Gas Safety (Installation and Use) Regulations 1998, issued by the Gas Safe registered engineer who did the work. You'll need this when you sell the property, and some insurers ask for it if you make a claim involving the heating system.
REGULATIONS & SAFETY
Oil boilers are common in properties off the mains gas network, need an oil storage tank with its own maintenance and safety considerations, and are serviced by OFTEC-registered engineers rather than Gas Safe (which only covers gas). If you're off-grid, confirm your engineer's OFTEC registration specifically.
HOW IT WORKS
An oversized boiler costs more to buy and can run less efficiently; an undersized one struggles with demand, particularly hot water for multiple bathrooms. Sizing should be based on a heat loss calculation for the property and how many bathrooms/hot water outlets are used at once, not just the previous boiler's output copied across.
LOCAL AREA
Greenwich falls under Greater London and the London region with the SE10 postcode district, and is designated here as a large town. Although no population figure is supplied, SE10 identifies an inner‑London riverside area administered by the Greater London authority, signalling a mix of historic and modern development and tourist activity. For tradespeople, the SE10 postcode helps users find contractors experienced with riverside properties and central London access restrictions, including potential congestion zones and limited parking. Hiring in Greenwich typically requires trades comfortable working in conservation settings or on older buildings, as well as coordinating deliveries in busy urban streets; access for vans and scaffolding permits can be significant considerations. Buyers and landlords should look for contractors knowledgeable about working around high-footfall public spaces and the particular logistical challenges of inner-London projects.
Heating engineers in Greenwich must be comfortable working across a wide housing stock, from older period homes that need boiler replacement and powerflushing to modern riverside developments where heat pumps or communal systems may be present. Any gas boiler installation or servicing must be carried out by a Gas Safe registered engineer — essential for legal compliance and safety in densely built areas. Older properties in SE10 often collect sludge in radiators and pipework, making powerflushing a common preparatory step before fitting a new boiler or radiator; engineers will assess whether radiators and pipework need upgrading for efficient heat delivery.
Where mains gas is unavailable, engineers with experience of LPG, oil or electric systems are helpful, and in inner‑London projects logistics like access for plant, scaffold permits and timed deliveries are important to plan. When appointing a heating engineer in Greenwich, check Gas Safe registration, ask for a written service or commissioning record, and confirm how they will manage deliveries and equipment access in restricted central‑London streets.
