Boiler Installation Survey
A boiler installation survey is the first step to a safe, correct boiler replacement. It checks your existing heating and hot water setup, confirms what will and will not work in your property, and sets out a clear plan for the new boiler so you can proceed with confidence.
More information
What the boiler installation survey covers
A pre-installation survey reduces guesswork and helps avoid delays on installation day. It focuses on safety, suitability, and getting the specification right.
- Review of your current boiler and heating system layout
- Assessment of hot water demand and boiler sizing guidance
- Checks on flue route options, termination position, and condensate drain route
- Review of gas pipe sizing and whether upgrades may be required
- Location and access checks for installation, servicing, and future maintenance
- Review of controls, cylinder (if applicable), and options for improving efficiency
- Identification of any remedial work needed to meet current standards
- Clear explanation of next steps, timescales, and what the installation will involve
When this service is most useful
- You are replacing an older boiler and want to avoid unexpected extras.
- You are moving from regular to system or combi and need to confirm feasibility.
- You have issues such as low pressure, poor hot water performance, or uneven heating.
- You are a landlord or small commercial client who needs a documented, planned approach.
What happens during the visit
The survey is carried out on-site so the system, pipework routes, and practical constraints can be seen first-hand. You can expect straightforward questions about your hot water use, heating performance, and any future plans (for example, bathroom changes or extensions). The findings are then used to shape a compliant, workable installation plan.
After the survey
You will receive clear recommendations on the right boiler type and any necessary system work. If you decide to proceed, the survey information is used to plan the installation efficiently and support the required safety and compliance steps.

After a few days of an old boiler that needed replacing, we gave them a ring. The engineer who came out was polite and knew their stuff. It was dealt with quickly, which was a relief. Clear, professional service from start to finish. I'd happily book them again. Couldn’t fault it.

We'd been putting up with an old boiler that needed replacing and finally called. Mark turned up on time and was a pleasure to deal with. They explained the next steps clearly before turning up. We finally have peace of mind. Wouldn't hesitate to recommend them. 5/5.
