Thinking about a new boiler?

If your current boiler is over 10 years old, breaking down regularly, or your bills are creeping up for no obvious reason, it might be time to replace. A new A-rated condensing boiler can cut your gas bill by 20·30% · that's £250-£400 per year back in your pocket for an average 3-bedroom home.

The brands I fit

Worcester Bosch

The UK's most popular boiler brand for good reason · rock solid reliability, great warranty, widely available parts. The Greenstar 4000 is my go-to for most homes. 10-year warranty when I fit it. Expect £2,000·£3,200 fitted depending on system.

Vaillant

German engineering, beautifully built, quieter than most. ecoTEC Plus is the workhorse model. 10-year warranty available. Slightly pricier than Worcester but worth it if you're keeping the property long-term. Expect £2,200·£3,500 fitted.

Baxi

Solid British brand, competitive pricing. Baxi 600 is a great mid-range combi with a 10-year warranty. Best value for money in my experience. Expect £1,800·£2,800 fitted.

Ideal

Ideal Logic Max is the one I recommend · simple, reliable, easy to service, and the cheapest route to a new A-rated boiler without compromising on build quality. 10-year warranty. Expect £1,700·£2,600 fitted.

How the process works

1. Free in-home survey (30-45 minutes)

I come out at a time that suits you, look at your current boiler, measure up the space, check the gas supply, flue route and hot water demand. No obligation, no pressure.

2. Fixed written quote within 24 hours

I email you a detailed quote listing the recommended boiler (usually 2·3 options at different price points), all the parts needed, the labour breakdown, timescale, and warranty details. The price is fixed · no "ah actually we found extra work" on install day.

3. Installation day

Most standard combi swap-outs take 1 day. System and conventional boiler conversions or moves take 2·3 days. I'll give you an exact timeline in the quote. On the day I arrive when I said I would, lay down dust sheets, protect your floors, and work cleanly. You'll have hot water and heating back by evening on a same-day install.

4. Commissioning & handover

Once installed, I run the full commissioning checklist: gas tightness test, combustion analysis, flue check, controls test, radiator balancing, and a full run-through with you on the new controls. You get all the paperwork · Benchmark certificate, gas safety record, warranty registration, and manufacturer manuals.

5. Warranty registration

I register the warranty with the manufacturer on the day. You get the full 10-year cover as long as you keep up with the annual boiler service · which I'll automatically remind you about 11 months later.

Power flushing

If I'm fitting a new boiler to an older central heating system, I'll usually recommend a power flush to clear out any sludge that could damage the new boiler. Kamco power flush trained · it's a one-time job that protects your new boiler investment. Quoted separately in the survey.

Financing

I don't offer direct finance, but if you're looking to spread the cost I can point you at reputable 0% finance options through the manufacturer. Worcester, Vaillant and Baxi all have partner finance schemes. We can chat through it during the survey.

FAQ

Boiler installation questions

How much does a new boiler cost in Croydon?

Most installs in Croydon range from £1,700 to £3,500 fitted, depending on the boiler brand, type (combi vs system), whether we're relocating it, and the condition of existing pipework. I do free in-home surveys and give you a fixed written quote within 24 hours · no surprises.

How long does a boiler installation take?

A standard combi swap-out (new boiler in the same spot as the old one) takes 1 day. Conversions from system to combi, or relocations, take 2·3 days. I'll tell you exactly in the quote and stick to it.

Which boiler brand do you recommend?

Depends on your budget, how long you're staying in the property, and the demand on hot water. Worcester Bosch is my go-to for reliability. Vaillant if you want the best build quality. Baxi and Ideal if you're looking for best value without compromising warranty. I'll talk you through the options in the survey.

Do you offer warranty on new installations?

Yes · all my installs come with the full manufacturer warranty (typically 10 years), which I register on the day. The warranty is valid as long as you keep up with the annual boiler service.

Do I need a power flush?

If the existing central heating system is more than 10 years old and has never been flushed, then yes · sludge and debris in old pipes can damage a new boiler's heat exchanger and void the warranty. Kamco power flush trained. Quoted separately.
