We discuss your heating needs and survey your property to recommend the perfect boiler system tailored to your specific requirements.

You'll receive a comprehensive, no-obligation quote outlining all costs, boiler options, and potential energy savings.

Our Gas Safe engineers complete your installation efficiently, demonstrate the system, and provide all necessary documentation and warranties.

In some cases, yes. If your boiler is older, has an unknown service history, or shows signs of existing issues, we may need to conduct an initial inspection before your full cover begins. This helps us confirm the system is safe, working properly, and suitable for the plan.
If you're unsure, the best next step is to contact us with your boiler details so we can advise if a pre-check is needed.
A boiler care plan is designed to cover future servicing and breakdown support rather than faults that already exist when you sign up. If your boiler has a known issue, we would normally need to diagnose and repair that problem first.
Once your boiler is working properly, we can then advise on the most suitable plan for you.
Yes, you can often move to a higher level of cover if your needs change. This can be useful if you want broader protection, have upgraded your heating system, or simply want more support included over time.
The exact timing and start date for upgraded cover may vary, so it's worth checking with us before making the change.
You can arrange appointments directly with our team. Once you're on a plan, simply contact us when your service is due or if a problem develops, and we'll help organise a suitable visit.
For smoother booking, it helps to have your address, plan details, and a short description of the issue ready when you get in touch.
We can often cover older boilers, but suitability depends on their age, condition, and parts availability. If a boiler is heavily worn, unreliable, or no longer practical to maintain, care plan options may be more limited.
A quick assessment from our team can help confirm whether cover is realistic or if a replacement might be the better long-term option.
If you replace your boiler, your existing plan may need to be updated to match the new appliance and any warranty requirements. In some cases, your cover can continue with a few changes, while in others a different plan may be more suitable.
It's best to tell us as soon as you're planning a replacement so we can guide you on the right next step.
