Does a modern mid-terrace (1980–2010) qualify for the Boiler Upgrade Scheme?

Yes — the £7,500 BUS grant applies to any owner-occupied or privately rented property in England or Wales with a valid EPC. Smallest pre-install scope of any pre-2010 archetype — fabric is usually already band C or close to it.

What size heat pump do I need for a modern mid-terrace (1980–2010)?

4–7 kW thermal output is typical, with 6 kW being the median. The exact size depends on a heat-loss calculation per BS EN 12831, which your MCS-certified installer performs on a site visit.

What pre-install work is typically needed?

Usually nothing on fabric — EPC band C is already common. Hot water cylinder install (~£1,500–£2,500) is the main scope item. An MCS-certified installer will confirm the exact scope on a site visit and price it into the quote.

Heat pump for a Modern mid-terrace (1980–2010): 2026 cost + sizing guide

What makes a modern mid-terrace (1980–2010) different

Late-20th-century purpose-built terrace with cavity walls and double-glazing, typical 70–95 m² floorplate.

From a heat-pump-sizing perspective, a modern mid-terrace (1980–2010) has a design heat loss of 40–65 W/m² at the UK standard −2°C external design temperature (per PAS 2035). That translates to an annual space-heat demand of around 6,500–11,000 kWh and a recommended air-source heat pump capacity of 4–7 kW thermal. Smaller than gas-boiler sizing typically lands at — heat pumps run 24/7 at lower flow temperatures rather than cycling at 70°C.

Parameter	Typical range	Notes
Floor area	70–95 m²	BEIS English Housing Survey median.
Design heat loss	40–65 W/m²	At −2°C external (UK design temp).
Annual heat demand	6,500–11,000 kWh	Space heating only, not DHW.
Recommended ASHP size	4–7 kW	Per BS EN 12831 sizing.
Pre-grant install cost	£9300–£14000	Including pump, cylinder, 1–3 radiator upgrades.
After BUS grant	£1800–£6500	£7,500 deducted by installer at invoice.
Common EPC band	Band C	Before retrofit work.
Typical install time	2–3 days	Whole-house including cylinder + radiator swaps.

BUS grant eligibility specifics for this property type

Smallest pre-install scope of any pre-2010 archetype — fabric is usually already band C or close to it.
Mid-terrace = no side-passage access; outdoor unit MUST go in the rear garden or on the rear wall, which restricts placement options.
Typically gas-combi heated; the cylinder install is the biggest single line item in the BUS-grant scope.

Pre-install upgrades typically needed

Most modern mid-terrace (1980–2010)s need some fabric or radiator work before the heat pump can be commissioned. The most common scope:

Usually nothing on fabric — EPC band C is already common.
Hot water cylinder install (~£1,500–£2,500) is the main scope item.
Radiator upgrade in 1–2 rooms — modern terrace radiators are often already adequate for 50°C flow.
Outdoor unit access through the house to rear garden — most installers handle this but adds half a day.

The full scope is set by your MCS-certified installer’s heat-loss calculation. Most installers absorb the radiator swap and cylinder install within the BUS-grant pricing — you don’t have to coordinate them separately.

Is this archetype right for you?

Owner-occupiers of post-1980 mid-terraces who want a clean, cheap-as-it-gets BUS install with minimal fabric work. Often the lowest net-cost archetype.
