Our online quote tool asks a few simple questions about your property and heating system. Based on your answers, we generate a fixed-price boiler installation quote in under 60 seconds.
All quotes generated online are fixed-price based on the details provided. If anything needs adjusting after a survey, we’ll explain it clearly before any work goes ahead.
A typical installation includes, the boiler, flue, magnetic filter, Limescale reducer (for combi’s), standard pipework, system flush, commissioning, and a free wireless thermostat with selected boilers.
In many cases, we can offer next-day boiler installation or the day after, depending on availability and the type of job. We always aim to get your heating up and running as quickly as possible.
Your old boiler is safely removed and disposed of as part of the installation, and we leave the work area clean and tidy once the job is complete.
