What does installation cost in Sunderland?

Between £8,000 and £14,000 before funding; knock off the £7,500 grant and most Wearside households finish somewhere between £1,500 and £6,500.

How many days does the work take?

Three to five on most houses, with hot water down for only part of one of them. Heavy radiator programmes extend that.

What capacity will my house need?

Commonly 5kW to 7kW on an interwar semi, rising to 10kW or 12kW on a large terrace. The measured calculation decides, and oversizing hurts price and efficiency alike.

Does the gas boiler have to be removed?

On a full conversion, yes; the gas gets capped or kept for a hob. A hybrid keeps the boiler on purpose.

Air source heat pump installation in Sunderland

Budget £8,000 to £14,000 for a Sunderland air source installation in 2026, before the installer claims the £7,500 Boiler Upgrade Scheme payment and deducts it from your bill. That figure buys the outdoor unit, hot water cylinder, radiator work, pipework, electrics, commissioning and certification.

The components of a Sunderland installation

A full job is a complete heating system. It typically brings a 5kW to 12kW monobloc unit, an unvented hot water cylinder sized between 180 and 250 litres, upsized emitters wherever the measured design calls for them, new 22mm or 28mm primaries where the existing pipework is undersized microbore, a dedicated electrical circuit, controls, commissioning and MCS certification. Sizing is calculated, not guessed: a Fulwell semi of around 90 square metres usually computes to 5kW to 7kW, while a tall Ashbrooke terrace over three floors can reach 10kW to 12kW.

What moves the price within the range

Radiator work: the biggest lever. Two or three swaps is routine; a full emitter programme with lifted floors is a different job.
Cylinder position: an airing cupboard reuse is simple; a loft cylinder with new insulated pipework adds cost.
Electrics: older terraces occasionally need the consumer unit brought up to scratch first.
Coastal siting: at Roker, Seaburn and other exposed streets the unit position and corrosion protection get extra design attention.
Capacity: bigger machines cost more; a 12kW unit carries a clear premium over a 5kW one, ahead of any brand choice.

From survey to switch-on

The measured survey and design come first, then a written price with the flow temperature stated. Installation runs three to five days on most Sunderland houses: base and unit, cylinder and emitters, commissioning and handover, with hot water off for part of one day. Certification and the £7,500 grant claim follow commissioning, and the grant is already reflected in your quoted figure.

When we advise against it

A solid-wall terrace that cannot hold warmth below 55 degrees wants its insulation seen to first. A flat without a permitted outdoor position is ruled out. A house with a young boiler and a tight budget can be better served by a hybrid. Those calls are made at the survey, while the survey fee is still the only money spent. The numbers behind every option are in the cost guide.
