As a rough guide for Blackburn (BB1, BB2): 1–2 bed flat → 24–28kW combi; 2–3 bed terrace → 28–30kW combi (Worcester 4000, Baxi 800); 3–4 bed semi → 30–35kW combi or 18–24kW system + 180L cylinder; 4+ bed with two bathrooms → 28kW system + 210L+ Megaflo unvented cylinder. In Blackburn specifically: BB1 (Blackburn east): we still see a high proportion of old back-boilers and 1990s wall-mounted Potterton Profile boilers here, ripe for combi conversion. BB2 (Blackburn west): mostly second- or third… We always do an in-person heat-loss + flow-rate survey before quoting.

If your current system is older than 10 years or you have any sludge symptoms — cold spots on radiators, banging/kettling, frequent blockages, dirty water when bleeding rads — a powerflush is almost always worth doing before a new boiler goes in. Worcester Bosch requires a system clean for the extended warranty to be valid. In Blackburn, where older mid-terrace pipework is widespread, around 60% of our installs include a powerflush — typically £450–£950 added to the install quote.

Manufacturer warranty calls (Worcester, Baxi, Vaillant) go directly to the manufacturer's engineer network — call the number on the boiler casing or the warranty pack we hand over on install day.
