If you’re searching for boiler installation in Twickenham, you’re probably looking for one of three things: a reliable upgrade to reduce breakdowns, a more efficient heating system, or a safe replacement after your current boiler has failed. Twickenham (TW1 / TW2) has a mix of flats, period properties and family homes, so the “right” boiler and setup depends on your hot water demand, heating layout and the condition of your existing pipework and radiators.
A new boiler can make a big difference to comfort and running costs — especially if your current boiler is old, unreliable, or struggling to heat the home evenly.
You may want to consider a replacement if you’re dealing with:
Frequent breakdowns or repeated repair bills
Noisy operation (banging, kettling, whistling)
Low pressure issues or ongoing leaks
Heating that takes a long time to warm up
Hot water that runs out quickly (or fluctuates)
Outdated controls and poor efficiency
Age UK also notes that if your boiler is over 12 years old, it may be worth thinking about replacement, and strongly advises using a Gas Safe registered installer for gas heating work.
We fit and replace boilers for homes and properties in Twickenham and nearby areas (including St Margarets, Strawberry Hill, Whitton, Richmond, Teddington and Isleworth).
Typical installation services include:

Advice on radiator performance and system condition
Any work on a gas boiler must be done by a Gas Safe registered engineer. HSE guidance explains that while a non-registered person may do some “wet work” (like installing water pipes/radiators), work on the gas boiler itself and final connection to the boiler must be completed by a Gas Safe registered engineer.

A professional install starts with understanding:
Property size and number of bathrooms
Hot water demand (how many taps/showers may run together)
Existing heating layout and pipework condition
Boiler location and flue route options
Any recurring issues (cold radiators, pressure loss, noise)
This is where you choose the correct boiler type and output — not too small (poor performance), not oversized (inefficient cycling).
A quick guide:
Combi boiler: Great for many flats and smaller/mid homes; hot water on demand, no cylinder.
System boiler: Better for higher hot water demand; works with a cylinder and can support multiple bathrooms more easily.
Regular boiler: Often used in older systems; usually replaces like-for-like where a traditional setup already exists.
On installation day, the engineer removes the old boiler (where applicable), fits the new unit, checks the system, and commissions it in line with manufacturer instructions.
Industry documentation also highlights that installers should be competent to install/commission and “notify (where appropriate)” the work, and customers should receive evidence the boiler has been installed correctly. Heating and Hotwater Industry Council
A quality installation includes:
Explaining how to use the heating controls properly
Basic guidance on pressure/top-ups (where relevant)
A completed commissioning record
The Benchmark commissioning checklist is widely used as a record that commissioning has been completed and is intended to be handed to the customer for future reference.

How do I know which boiler type I need?
It depends on your property size and hot water demand (e.g., number of bathrooms and how many outlets may run at once). A site assessment is the best way to choose correctly.
Is there guidance about efficiency requirements?
Yes. Approved Document L provides statutory guidance for conserving fuel and power (energy performance standards).
