HEATING TIPS
Useful guidance to help you prepare, understand pricing and find a trustworthy Heating Engineer.
RULES & STANDARDS
Electric boilers avoid combustion entirely (no flue, no CO risk, no Gas Safe requirement) but electricity typically costs more per unit than gas, so running costs can be higher for the same heat output. They suit smaller properties or as a backup rather than being the default choice for most UK homes.
WORKMANSHIP STANDARDS
A proper quote should specify the boiler make and model (not just "a combi boiler"), whether a powerflush is included, the warranty length, and what certificate you'll receive on completion. If a quote is missing the boiler model, ask before agreeing.
SAFETY & COMPLIANCE
Installing or servicing a gas fire, gas stove, or gas oven/hob is gas work under the same legal framework as a boiler — it must be done by a Gas Safe registered engineer qualified in that specific appliance category, not just any gas-qualified engineer, since categories are appliance-specific.
SAFETY & COMPLIANCE
Manufacturer warranties on new boilers commonly run 5-10 years, but usually require annual servicing by a registered engineer to stay valid — check whether it has to be the same installer or any Gas Safe engineer. This is separate from any workmanship guarantee the engineer offers on their own installation work.
REGULATIONS & SAFETY
A quote well below others is worth questioning — check it specifies a named boiler make and model (not just "combi boiler"), includes a powerflush if the system is older, and states the warranty length. No Gas Safe registration number offered unprompted is a clear red flag.
UNDERSTANDING THE JOB
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.
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.
UNDERSTANDING THE JOB
The boiler itself is often the largest single cost, but labour, flue work, and any additional pipework or radiator changes add up. If a quote looks cheap, check it specifies the same boiler tier (entry-level vs mid-range) as a competing quote, not just a lower labour charge.
LOCAL GUIDE
Catford is a district in south‑east London and the administrative centre of the London Borough of Lewisham, mostly within the SE6 postcode district; the 2011 population for Catford including Bellingham was 44,905. The area is identified in the London Plan as one of 35 major centres in Greater London. As the borough administrative centre, planning, building control and public services for Catford are managed by Lewisham Council. For trades and homeowners, SE6 indicates an established urban area where contractors commonly undertake internal refurbishments, structural works and external repairs; being a major centre also means a range of specialist contractors are readily available. When sourcing trades, check whether any works fall within conservation zones or require council permits for scaffolding and temporary roadspace, and discuss logistics for deliveries in busy shopping or civic streets.
Catford’s SE6 urban context, with a high proportion of older Victorian and early 20th‑century housing, means heating engineers frequently replace ageing boilers and perform powerflushing to clear sludge from radiators and pipework. Many properties are on mains gas, but engineers should still assess each property’s fuel type and distribution system to recommend the right solution, including potential upgrades to more efficient systems like heat pumps where appropriate.
Gas work must be carried out by a Gas Safe registered engineer and homeowners should insist on the registration number before any work begins. Urban projects also demand clear planning for access and parking for delivery of boilers or radiators, and engineers should include servicing and commissioning paperwork to satisfy warranty and insurance requirements. Ask for proof of Gas Safe registration, examples of similar installs in SE6 homes, and a clear plan for how they will manage equipment delivery in busy streets.
