You’ll see “supply and fit” offers everywhere. The boiler is the shiny bit — but the cleaning, protection, controls and commissioning decide whether you forget about it for 10+ years or keep googling error codes at 7am.
If you’re considering a new boiler because it’s “always something”, it helps to separate urgent faults from problems that can wait — especially if the home has gone cold or you’ve noticed moisture near the unit.
We look at bathrooms, hot water demand, water pressure, pipework size and how the home is used. Then we recommend what fits — not “biggest boiler = safest”.
Helpful before any quote: boiler sizing guide.
London installs often depend on flue position and condensate routing — especially in flats, conversions and side returns. We plan this properly so it stays safe, compliant and reliable.
If you’re unsure: flue rules + condensate guidance.
A new boiler on a dirty system still suffers. We assess whether you need a chemical clean or power flush, then fit the right protection so the boiler isn’t being set up to fail.
We set sensible flow temps, check pressures, confirm safe operation, register warranties, and walk you through controls so you’re not heating the house like it’s 2003.

Boiler installs in London aren’t “harder” because the boiler is different — they’re harder because buildings are. Access, parking, stairs, shared flues, restricted routes for condensate, and cupboard conversions can all change the plan. If you’re trying to sanity-check budgeting, see boiler installation cost for a flat or house. And if you’ve ever wondered why boiler installation costs more in London, that guide breaks down the real reasons without sales fluff.
Many flats rely on specific flue routes and condensate options, and some buildings have restrictions that affect what can be installed and where. We check the route, the terminal position and the safest compliant option.

A true like-for-like swap is usually straightforward. Costs can change when pipework needs re-routing, controls need updating, a filter is missing, or a system clean is required.
If you’re comparing quotes, check: power flush guidance and filter + inhibitor.
Things that extend time are usually access related (parking/stairs), changing boiler type, flue/condensate complexity, or extra pipework and controls. We’ll always explain what’s essential vs optional.
Before you decide on warranty: warranty lengths explained.
If it’s a rental, the paperwork and safety checks matter as much as the install. We can advise on what’s needed, and keep everything documented properly.
If the boiler fails out of hours: night emergency boiler steps.
Pricing depends on boiler type, flue/condensate route, controls, cleaning requirements and access. Instead of trying to force a “from £X” number onto every home, we keep pricing detail inside our cost guides.

Not always, but a clean system matters. We assess whether a chemical clean or power flush is needed, then fit protection so the new boiler isn’t being set up to fail. Read: power flush with a new boiler.
