How We Install
NO SHORTCUTS
We know that a new boiler or full central heating system is a large investment. It is a false economy to fit a substandard boiler or to take short cuts with inadequate gas supply pipe or by fitting to a dirty system. Fitting this way will at best lessen the efficiency of your boiler and at worst will cause repeated brake downs.
We will ensure your new boiler is installed by using the most up to date modern practice. We will always carry out a full Powerflush to your system , fit a magnetic filter, fit limescale reducer to Protect Your New Boiler and fit digital carbon monoxide detector to Protect You!

Frequently Asked Questions
The size of your home and the number of radiators you have will determine the cost of a new combi boiler. A new combi boiler for a small one-bedroom flat with only five radiators will cost much less than a new combi boiler for a large detached house with lots of bedrooms, bathrooms and radiators.
For Combi Swap Installations in the same place, we charge £650
It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system.
Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.
Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed.
Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.
No, you cannot legally install your own gas boiler unless you have appropriate certification. Only Gas Safe registered engineers can install gas boilers, while Oil Firing Technical Association (OFTEC) registration is required for anyone installing oil boilers.
A plumber cannot install a boiler unless they’re Gas Safe or OFTEC registered. Whilst a plumber can service plenty of other components of your heating and hot water system, they can’t legally install a boiler without the appropriate certification, which only heating engineers usually have.
