Condition ratings
The boiler looks old. Is its age, on its own, a condition rating?
No. A boiler that looks old has not, by its age alone, been given a condition rating. Age is a description. A rating is a judgement that something needs repair, or does not. The surveyor may still comment on leaks, corrosion, or a poor flue they could see. Those observations, not the year it looks, are what a number would rest on. Services were looked at, not safety-tested.

What is the fuller explanation?
Looking old is not one of the three definitions. Rating 1 means no repair is currently needed, only normal maintenance. Rating 2 means a repair or replacement is needed but it is not serious or urgent. Rating 3 means serious, urgent, or both, and written quotations before legal commitment. A surveyor can apply one of those to a boiler because of what they saw: a leak, heavy corrosion, a damaged case, or a flue that looks unsafe to the eye. They cannot apply one because a casing looks dated. If the report gives no number, age has not created one. Do not write rating 3 in the margin because you would prefer a new boiler.
Services are inspected visually. They are not safety-tested, so neither age nor a rating is a certificate that the boiler burns safely or that the controls work. The what to do now note advises you. It does not invoice the seller for a new boiler, and it does not turn a preference into rating 3. An R mark, if one appears beside a request for service papers, is a document prompt, not a condition rating. Ask what was actually seen, and whether any number was given. If you want the appliance tested, that is a separate instruction to a heating engineer, not a reading of the year it was made.
What should you ask your surveyor?
- Did you give the boiler a rating, or only note that it looks old?
- What visible defect, if any, sits behind that comment?
- Are you clear the boiler was not safety-tested?
What are the typical next steps?
- Do not turn the boiler's age into a condition rating.
- Ask which defects were seen, separate from age.
- Commission a heating check only if you want a test the survey did not do.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
Can an old boiler still be rating 1?
Yes, if nothing they saw needs repair now. Age does not forbid rating 1, and it does not require it.
If there is a leak under the boiler, is that the age?
No. A leak is a defect. Ask what rating they gave the leak, and keep age out of it.
