Our Heating & Boiler Services in London
We cover the full range of domestic heating work a London homeowner or landlord is likely to need, from a one-off repair to a full system installation.
Boiler Repair London
A faulty boiler is usually fixable the same day. Our engineers diagnose the fault on-site, quote the repair cost upfront, and carry common parts on the van to avoid a second visit wherever possible. Typical issues include no heat, no hot water, error codes, leaks, and loss of pressure.
Emergency Boiler Engineer London
If your boiler has broken down completely, we offer 24/7 emergency callouts, including evenings and weekends. Priority is given to households with no heating or hot water, especially where vulnerable occupants are affected.
Boiler Servicing London
An annual boiler service checks for gas safety, efficiency, and early signs of wear, and keeps your manufacturer warranty valid. It takes most engineers 30–45 minutes and should be done every 12 months regardless of how the boiler is performing.
Boiler Installation & Replacement London
New combi boiler installation starts from £1,399, fixed price, fully fitted in a single day for most standard swaps. We supply and install Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Viessmann, Alpha, Grant, and Potterton boilers, all backed by manufacturer warranties.
Combi Boiler Engineer London
Combi boilers are the most common choice for London flats and smaller households because they don’t need a separate hot water tank. Our engineers assess your property size, number of bathrooms, and water pressure to recommend the right kW output before you buy.

Boiler Fault Finding & Diagnosis
Recurring faults, unexplained pressure loss, or repeated error codes usually point to an underlying issue rather than a one-off fault. Our engineers carry out full diagnostic checks to identify the root cause, rather than only treating the symptom.
Power Flush London
A power flush clears sludge, rust, and limescale from radiators and pipework, restoring even heat distribution and protecting a new or existing boiler from damage caused by circulating debris.
Landlord Boiler Services & Gas Safety Certificates
Landlords are legally required to have gas appliances checked annually by a Gas Safe registered engineer and issued a CP12 gas safety certificate. We offer combined servicing and certification visits to minimise disruption to tenants.
