Factors affecting cost in the UK
- ·Whether existing pipework can be reused.
- ·Radiator type — standard panel vs designer / vertical.
- ·Access — solid concrete floors need chasing or surface boxing.
- ·Number of radiators in one visit — bulk install reduces per-rad cost.
- ·Region — London adds 25–35%.
Ways to reduce cost
- ·Bundle multiple radiator changes into one visit — saves on call-out and balancing time.
- ·Buy standard panel radiators from Screwfix, B&Q or Plumbase — same quality as merchants.
- ·Choose standard panel over designer in low-traffic rooms (bedrooms, hallways).
- ·Reuse existing pipework where it lines up with the new radiator size.
- ·Add TRVs to every radiator while the system is drained — cheap upgrade with long-term savings.
Frequently asked questions
- How long does a radiator install take?
- 1–3 hours for a like-for-like swap, half a day for new install on existing pipe, a full day for new pipework runs.
- Can I install a radiator myself?
- Like-for-like swaps can be DIY if you're confident draining the system. New pipework and gas-system connections should go to a qualified plumber.
- Do I need to balance the system after a new radiator?
- Yes — adding or moving radiators changes flow. A balance takes 30–60 minutes and is usually included in install labour.
- Are vertical radiators worth the extra?
- Yes in small rooms and hallways where wall height is more useful than width. Output per £ is lower than standard panels.
- What size radiator do I need?
- Calculate room heat loss in watts (about 50–70 W/m³ for a UK insulated home). A plumber will confirm before quoting.
- Will my warranty be affected by adding radiators?
- No, provided the system inhibitor is topped up and the new radiators are within the boiler's rated output.
