We cover 11 towns and cities in Suffolk, including Ipswich, Lowestoft, Bury St Edmunds and Haverhill. Every installation is designed from a room-by-room heat loss calculation, so the heat pump, radiators and cylinder are sized for the house rather than guessed.

Grants and rules for heat pumps in England
Homes in Suffolk can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Questions
Do I need new radiators for a heat pump?
Whether you need new radiators depends on each room's heat loss: some homes need a few larger radiators, while others can keep most of their existing ones. Heat pumps run most efficiently at low flow temperatures, around 35–50°C, so a radiator gives out less heat than it did with a boiler. The room-by-room heat loss calculation shows which rooms need a bigger radiator. A replacement radiator sized for a heat pump is a guide price of £250–£450 each, installed and including VAT.
What warranty comes with a heat pump?
A new heat pump comes with a manufacturer warranty, which passes to you, and the length depends on the make and model. Our workmanship guarantee is set out in writing in your quote. Manufacturer warranties usually depend on the system being registered and serviced as the manufacturer requires, so keep your handover pack, MCS certificate and service records together. We explain the warranty conditions for your chosen unit before you accept the quote.
Do I need space for a hot water cylinder?
Yes, an air source heat pump needs a hot water cylinder, because there is no combi-style equivalent that heats water on demand. If you have a combi boiler now, we find a suitable place for a cylinder, such as an airing cupboard, utility room or garage. Slimline and compact cylinders can suit smaller homes. A cylinder is included in our full-system guide price, and we agree its position with you at survey.
How do I pay for my heat pump installation?
How and when you pay is set out in your written quote, so you know the full price and any payment stages before you agree to anything. Nothing is ordered until you accept the quote. Where a grant applies, such as the Boiler Upgrade Scheme in England and Wales, it is deducted from the price shown. If you have questions about payment, ask at the survey and we will explain how it works for your job.
