Why Choose Fixed-Price Fitting?
Many companies quote for the boiler only and then add labour separately — which can lead to unexpected bills. Here's why fixed-price fitting is the better choice:
- No surprises — you know exactly what you'll pay before we arrive
- All labour included — the engineer's time is part of the quoted price
- No upsells on the day — we don't add extras once we're in your home
- Easier to budget — especially important if you're using finance
Our fixed prices cover a standard installation. If your installation has unusual complications (e.g. very old pipework needing replacement, significant flue changes), we'll identify these during the survey and quote transparently before starting.
What's Included in Our Fitted Price?
Every boiler price fitted by Next Gen Boilers Ltd includes:
- New boiler (supply and installation)
- New room thermostat or smart thermostat (Hive available)
- Magnetic system filter (Fernox TF1 or Adey MagnaClean)
- Chemical flush with inhibitor
- Removal and disposal of your old boiler
- Gas Safe installation certificate
- Manufacturer warranty registration on the day
There are no additional charges for these items — they are all part of the standard fitted price.
