If your radiators are not heating properly, you’re not alone. Inefficient or faulty radiators can increase energy bills, reduce comfort, and put extra strain on your boiler.
At BDS Services Limited, we specialise in radiator repairs, upgrades, and full heating system improvements across the West Midlands — helping you achieve reliable, energy-efficient heating all year round.
Common Radiator Problems We Fix
1️⃣ Radiator Cold at the Top, Warm at the Bottom
This usually indicates air trapped inside the radiator. Bleeding may temporarily help, but if the issue keeps returning, it could point to circulation or system pressure problems.
2️⃣ Radiator Warm at the Top, Cold at the Bottom
This is often caused by sludge and debris buildup inside the system. A powerflush or system clean may be required to restore efficiency.
3️⃣ Radiator Not Heating at All
Possible causes include:
Faulty thermostatic radiator valves (TRVs)
Blocked pipework
Pump issues
Incorrect installation
We diagnose and repair the root cause quickly and professionally.
4️⃣ Radiators Not Sized Correctly for the Room
If a radiator is too small, your room will never heat efficiently — meaning higher energy bills and poor comfort. We calculate the correct BTU output required for your space and recommend the right upgrade.

Radiator Upgrades – Type 11, Type 21 & Type 22 Explained
Upgrading your radiator can dramatically improve heat output without increasing running costs.
- Type 11 (Single Panel + 1 Convector) – Slim profile, moderate heat output
- Type 21 (Double Panel + 1 Convector) – Higher heat performance
Type 22 (Double Panel + 2 Convectors) – Maximum efficiency for larger rooms
If your current radiator isn’t delivering enough heat, upgrading from Type 11 to Type 22 can significantly improve warmth and efficiency.
Improve Efficiency by Upgrading Pipe Sizes
Many older systems use 8mm or 10mm microbore pipework, which can restrict water flow.
We can:
Upgrade pipework to 15mm copper
Improve circulation and heat distribution
Reduce cold spots
Enhance overall system efficiency
Better flow = better heating performance.
Full Heating System Upgrades Available
If your entire heating system struggles to keep up, we can:
Upgrade radiators throughout your property
