Before you book: heat pump radiator upgrades in Paisley
Homes around Paisley range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Radiator fitting in Paisley is scheduled with your heat pump installation so the system is drained only once. For period homes in Paisley and across Renfrewshire and Inverclyde, column radiators can keep the character of a room while giving enough heat at low temperatures.
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.
- Rooms with little wall space, where a fan-assisted radiator fits better
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Rooms that already feel slow to heat, such as bay-windowed living rooms
What's included
- Supply and fitting of new radiators, valves and brackets
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Room-by-room heat loss figures for every heated room
- A radiator schedule showing which radiators stay, which change and their outputs
- Balancing every radiator so each room heats evenly
We plan radiator upgrades in Paisley so floorboards are lifted only where pipework genuinely needs changing.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Paisley can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your Paisley property at survey.
Guide prices for heat pump radiator upgrades in Paisley
The ranges below are typical installed prices for homes in Renfrewshire and Inverclyde, including VAT. A survey sets the exact figure, because two similar-looking houses in Paisley can need quite different radiators and pipework.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £250–£450 |
| Upgrade of about 10 radiators | £2,000–£5,000 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,500–£3,500 |
Installed, inc VAT. The survey lists which radiators need changing.
Winter daylight and heating in Paisley
Paisley has about 6 hours 59 minutes of daylight at midwinter against 17 hours 35 minutes in midsummer. Heat pumps are designed to keep working well below freezing, but the design temperature for the survey is set for local conditions, not an average day.
What happens after you enquire in Paisley?
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Paisley home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat pump radiator upgrades in Paisley: questions
How long does installation take in Paisley?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Paisley home states the expected time.
How long does a heat pump survey take in Paisley?
A home survey in Paisley usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
What size heat pump does a Paisley home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Paisley home.
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.
Are fan-assisted radiators noisy?
Fan-assisted radiators make a low, steady fan sound when running at higher output, and many have quieter settings for bedrooms at night. They are useful where wall space is short, such as a kitchen with few clear walls. They need a small electrical supply, which we plan into the installation if you choose them.
