Nobody Budgets For A New Boiler. Then The Old One Makes The Decision For You.
It's rarely planned. A boiler that's been repaired twice this year finally isn't worth a third visit, and suddenly it's a bigger conversation than the one you called about.

A straight like-for-like swap is one job. Sizing a boiler correctly for a house with more radiators and bathrooms than it had when the old one went in, or converting from a system boiler to a combi, is a different one, and quoting them the same way is how people end up with a boiler that's technically new but still can't keep up with the house.
Willsway fits Worcester Bosch, Vaillant, Ideal, Baxi and Viessmann boilers, each carrying a manufacturer warranty of ten to twelve years when installed and registered properly, which only happens if the paperwork's done on the day, not chased up weeks later.
What Happens When You Call
A proper survey first
Radiators, hot water demand, flue route and existing pipework checked before anything's quoted, so the boiler recommended actually fits the house, not just the wall space.
Fitted, usually in a day
A straightforward like-for-like swap is typically a single day's work. Moving the boiler's location or converting system type takes longer, and you're told that upfront, not once the old one's already off the wall.
Controls explained, warranty registered
Benchmark paperwork completed and the manufacturer warranty registered before Sam leaves, so it's not something either of you has to remember to do later.
Real Reviews For This Job
“We have no hesitation to recommend Sam. We have called upon his services over a number of years to install a new boiler and radiators and for smaller bathroom issues. He is punctual, thorough and can be relied upon to do a good job.”
“Sam came and fitted us our new boiler in June last year, we wanted it also moved from the cupboard up to the loft, and I couldn't fault his work, he is friendly and professional, he also removed a radiator for us and we have just had him back to give the boiler it's annual service. I would recommend him to anyone. Thank you”

Boiler Installations & Replacements: The Questions People Ask
How long does fitting a new boiler actually take?+
A straightforward combi-for-combi swap is usually done in a day. Moving the boiler, converting from a system boiler, or adding an unvented cylinder takes longer, and you're given a realistic timeline at the survey, not on the day.
Combi or system boiler, which is actually right for my house?+
Depends on how many bathrooms are running hot water at once and whether there's room for a cylinder. Sam will recommend based on the house, not the boiler that happens to be easiest to fit.
What happens to the old boiler?+
Removed and disposed of properly as part of the job, not left for you to deal with.
Does the warranty registration happen automatically?+
No, and that's exactly the step that gets missed when it's rushed. It's registered with the manufacturer on the day of the install, before Sam leaves.
