Local knowledge
Boilers in Birmingham: what we see
Birmingham is the biggest patch we cover and it has just about every type of heating system going — B1 and B15 city-centre apartments on communal systems, the Victorian and Edwardian terraces of Sparkhill, Balsall Heath and Handsworth, 1930s semis right across Hall Green, Kings Heath and Erdington, and the larger detached housing out towards Edgbaston and Sutton.
That variety is exactly why so many Birmingham boiler quotes go wrong. A 24kW combi that suits a Selly Oak terrace will leave a four-bed in Moseley with a weak shower, and dropping a 35kW combi into a property with poor mains flow just wastes money — it can only heat water as fast as the mains delivers it. We measure flow rate and count radiator output on the day rather than quoting from a photo.
The older Birmingham housing stock also means we still remove a lot of back boilers behind fireplaces and gravity-fed systems with a cylinder in the airing cupboard. Those are two-day jobs done properly: old system stripped out, new combi sized and fitted, system flushed, magnetic filter added and the whole lot notified to Gas Safe and Building Control.
Birmingham water is moderately hard, so sludged radiators and scaled plate heat exchangers are the two faults we see week in, week out. Every install includes a full flush, fresh inhibitor and a magnetic filter as standard — and we'll tell you honestly whether a powerflush is genuinely needed before you pay for one.
Most requested jobs in Birmingham
Same-day boiler repairs
No heat or hot water anywhere in B postcodes? Call before midday and we aim to be with you the same afternoon with the common Worcester and Viessmann spares on board.
Back boiler removals
Still everywhere in Birmingham's older terraces and semis. Back boiler and cylinder stripped out, combi fitted, fireplace made good — normally two days.
Combi swaps
Straight like-for-like replacements across the city, usually completed in a single day with the heating back on that evening.
Landlord CP12s
Birmingham has a huge rental market. Gas safety certificates with same-week slots, tenants contacted directly and certificates emailed the same day.
Powerflushing
We own all the equipment and do it in-house from £495 inc VAT — the usual fix for radiators that are hot at the top and cold at the bottom.
Apartment & communal work
City-centre flats often have restricted flue routes and tight cupboards. We survey properly before quoting rather than turning up and finding it won't fit.

Birmingham boiler questions
Do you cover the whole of Birmingham?
Yes — all B postcodes, from the city centre out to Sutton Coldfield, Northfield, Erdington and Quinton. We're based in Halesowen, so the south and west of the city are on our doorstep.
How quickly can you get to a boiler breakdown in Birmingham?
Most breakdowns reported in the morning are attended the same day. South and west Birmingham — Harborne, Selly Oak, Northfield, Quinton, Edgbaston — are typically within 20 minutes of our base.
How much does a new boiler cost in Birmingham?
Our fitted prices start from £2,195 inc VAT for a Worcester Greenstar combi swap, including flue, fittings, full system flush, magnetic filter, controls and the Gas Safe building notice. The quote is fixed after a free survey.
What size boiler do I need for a Birmingham semi?
Most three-bed semis with one bathroom suit a 25–30kW combi. Two bathrooms or ten-plus radiators usually means 32–35kW, or a system boiler with an unvented cylinder if the mains flow can't support a big combi.
Can you replace a back boiler in a Birmingham terrace?
Yes, it's one of the most common jobs we do in the city. We remove the back boiler and cylinder, fit a correctly sized combi in the kitchen or a cupboard, and make the fireplace good.
Is Birmingham water hard enough to damage a boiler?
It's moderately hard — enough to scale a plate heat exchanger over time and cause lukewarm hot water. We fit a magnetic filter on every install and can add a scale reducer where it's worth doing.
