Before you book: heat pump radiator upgrades in Sedgefield
The question for a Sedgefield home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
We plan radiator upgrades in Sedgefield so floorboards are lifted only where pipework genuinely needs changing. Extensions and kitchen-diners around Sedgefield with large glazed areas get their own radiator calculation.
We size each radiator to your room-by-room heat loss so a heat pump can heat your home at a low, efficient flow temperature.
- Extensions and loft conversions with large areas of glazing
- Homeowners who want the lowest practical flow temperature for efficiency
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Supply and fitting of new radiators, valves and brackets
- Balancing every radiator so each room heats evenly
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Room-by-room heat loss figures for every heated room
Many older houses in Sedgefield still have their original single-panel radiators, so the survey checks each one against the room it heats.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Sedgefield quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Heat pump radiator upgrades in Sedgefield: questions
How long does installation take in Sedgefield?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Sedgefield home states the expected time.
How soon can you survey a home in Sedgefield?
Survey dates depend on how busy installers are in County Durham. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Sedgefield that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Sedgefield, whoever fitted them. Tell us the make and model when you book.
How much does a heat pump radiator cost?
A replacement radiator sized for a heat pump has a guide price of £250–£450 each, installed and including VAT. Upgrading about ten radiators in a typical home has a guide price of £2,000–£5,000. The final price is fixed in your written quote after the survey, once the radiator schedule shows exactly which radiators change.
Can radiators be changed without draining the whole system?
Radiator changes normally mean draining the heating system, which is why they are usually done as part of the heat pump installation. The system is then refilled, flushed, treated with inhibitor and balanced. Doing the radiators at the same time avoids draining twice and means the new radiators are commissioned with the heat pump.
