HEATING HANDBOOK
Helpful pointers for planning your project, understanding pricing and choosing a good Heating Engineer.
HOW IT WORKS
If you smell gas, don't use any electrical switches, don't light a flame, turn off the gas supply at the meter if it's safe to reach, and call the National Gas Emergency Service on 0800 111 999 before calling a heating engineer. For no heat or hot water without a gas smell, check the boiler pressure and any error code before assuming a full breakdown.
THE PROCESS EXPLAINED
Solar thermal panels heat water directly (different from solar PV, which generates electricity) and work alongside a conventional boiler or immersion heater as backup for when there isn't enough sun. They need a compatible cylinder with an extra heating coil, so retrofitting to an existing system isn't always straightforward.
HOW IT WORKS
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.
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.
HOW IT WORKS
On a new build or extension, "first fix" is running pipework to radiator and boiler positions before walls are closed up; "second fix" is fitting radiators, thermostats and the boiler itself once decorating is done. Getting boiler flue routing agreed early avoids conflicts with other trades later.
SAFETY & COMPLIANCE
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
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.
SAFETY & COMPLIANCE
You should receive a Benchmark commissioning checklist and a Gas Safety/Building Regulations certificate — keep both with your household paperwork. You'll need them to register the manufacturer's warranty (if not done automatically) and when you sell the property.
LOCAL GUIDE
Leatherhead lies in Mole Valley, Surrey, about 17 miles south of central London and uses the KT22 postcode district; it is recorded here as a town with a population around 12,000. Historically the settlement formed beside a ford on the River Mole and expanded with turnpikes and later railways; in the 20th century manufacturing gave way to service‑sector employers and business parks. Local planning and building control fall to Mole Valley District Council, so permission routes and conservation policies follow that authority’s processes. For those sourcing trades, KT22 narrows searches to contractors covering Surrey commuter towns and business parks; Leatherhead’s mix of older riverside properties and converted industrial estates means you may need both conservation‑accredited specialists and firms experienced in modern commercial fit‑outs. Access for vans is generally good, but riverside sites can have specific drainage and damp considerations.
Leatherhead’s housing and business-park mix means heating work ranges from replacing boilers in older riverside houses to installing efficient systems for modern offices and new-build commuter homes. Older properties commonly need boiler replacement and powerflushing to remove sludge and improve circulation, especially where original radiators and pipe runs survive; engineers experienced in retrofitting modern plant into limited spaces are valuable. In commercial or converted industrial buildings, there is demand for larger plant, underfloor heating and heat-pump solutions that meet modern efficiency standards.
Gas-related work must be carried out by Gas Safe-registered engineers — confirm registration for boiler installations, servicing and any gas appliance changes. For low-carbon projects like heat pumps, choose installers who can assess building fabric and advise on likely performance given Leatherhead’s mixed stock. When choosing a heating engineer, ask for Gas Safe ID, examples of work in both period domestic properties and commercial conversions, and a plan for any required system cleans (powerflushing) before installing a new boiler.
