Boiler Installation in Colchester
Replacing a boiler is the biggest heating decision most homeowners make. We size the system properly, fit it cleanly and register the warranty for you — across Colchester and North Essex.
The right boiler for your home
We survey your property, radiators and water pressure before recommending anything. That means you get a boiler matched to how many bathrooms and radiators you actually run, rather than an oversized unit that costs more to buy and to run.
Installed by Gas Safe engineers
Every installation is completed and certified by a Gas Safe registered engineer, with the system flushed, filters fitted and controls commissioned. We register the manufacturer warranty on your behalf and leave the paperwork with you.
Clean, tidy, on schedule
Most straightforward swaps are completed in a single day. We use dust sheets, take the old unit away and leave your home exactly as we found it. Where a full system upgrade is needed, we agree the timeline with you up front.
- What's included
- Combi, system & conventional boilers
- Worcester Bosch, Vaillant, Ideal & Baxi
- Up to 10-year manufacturer warranty

Boiler Installation: common questions
- How much does a new boiler cost in Colchester?
- A straightforward combi boiler swap typically starts around the mid-£2,000s including the boiler, fitting and certification. A full system conversion or a relocation costs more. We give a fixed written quote after a survey, so the price you agree is the price you pay.
- How long does an installation take?
- A like-for-like combi replacement is usually one day. Moving the boiler, converting from a conventional system to a combi, or adding a cylinder usually takes two to three days.
- What warranty do I get?
- Depending on the manufacturer and model, warranties run from 5 to 12 years. We register it for you at handover and service the boiler annually to keep it valid.
