Estimate what a boiler service or full replacement will cost you, and what financing a replacement would cost per month.
Typical range £80–£120 (Which? benchmark).
This tool gives you a realistic ballpark for either an annual service or a full boiler replacement, and — if you're replacing — what spreading the cost over a personal loan would actually add to your monthly outgoings versus paying upfront. Its main limitation is that boiler costs vary considerably by property type, boiler brand, access difficulty and region, so treat this as a planning figure rather than a quote, and always get at least two like-for-like quotes from Gas Safe registered engineers before committing.
