Why homeowners and landlords in Beckenham choose Prestige Engineers
A new combi boiler is one of the most impactful upgrades you can make to a London property. Modern condensing combis run at over 90% efficiency — compared to 60–70% for a boiler more than 15 years old. For homeowners in Beckenham heating a typical three-bed semi, the annual saving can exceed £400 on gas bills alone.
Prestige Engineers are Gas Safe registered heating engineers based in London. We install all major brands — Worcester Bosch, Viessmann, Vaillant, Baxi, and Ideal — and we stock the most popular models so we can often complete a straight replacement in a single day. Our engineers carry out a full system power flush before fitting, protecting the new boiler from sludge damage and keeping the 10-year warranty valid.
We handle every type of installation scenario. Replacing a like-for-like combi is the simplest job, but we regularly convert back boilers and system boilers to combis — reclaiming airing cupboard space, removing the cold water tank from the loft, and simplifying the pipework throughout the property.
For landlords in Beckenham with HMOs or rental portfolios, we offer bulk installation pricing and can coordinate works between tenancies. All installations are fully documented with a Building Regulations completion certificate and a Gas Safe commissioning record — essential if you ever sell or remortgage the property.
Choosing the right boiler brand matters. Worcester Bosch and Viessmann consistently top Which? reliability surveys and carry the longest manufacturer warranties — up to 10 years when installed by an accredited engineer and fitted with a magnetic filter. Vaillant ecoTEC models are a popular mid-range choice with excellent spare parts availability. For budget-conscious installs where longevity is less critical, Baxi and Ideal offer solid performance at lower upfront cost.
Every installation we carry out in Beckenham includes: removal and disposal of the old boiler, power flush of the existing system, supply and fit of the new boiler and flue, Magnaclean magnetic filter, dosing with corrosion inhibitor, wireless thermostat connection, and full commissioning and pressure test. We register the boiler with the manufacturer on your behalf and leave you with all warranty documentation.
New build or first-time heating system? We work from architectural drawings, design the pipework layout, and install the full system from scratch — compliant with Part L building regulations and ready for Building Control sign-off. We are experienced working alongside other trades on renovation and extension projects across Beckenham.

Combi boiler replacement
Old combi failing or beyond economic repair? We supply and install a new high-efficiency combi boiler from all major brands. Full system flush and commissioning included.

Magnetic filter fitting
A Magnaclean or equivalent magnetic filter removes sludge and protects your new boiler from corrosion damage. Most manufacturers require a filter for the 10-year warranty to apply.

Pair your new boiler with smart thermostatic radiator valves (TRVs) and a wireless thermostat or Hive / Nest system. Cuts fuel bills by up to 30% versus manual controls.
