Local housing

Heat loss survey Grimsby: local homes and building types

Grimsby has dense terraces near the older urban core, twentieth-century estates around it and newer detached development towards the western and southern edges. Those neighbourhood labels are useful for planning a visit, but they do not establish the fabric. Extensions, filled cavities, altered floors and roof work still have to be recorded at the property.

Housing mix

Terraces are a defining part of the urban housing mix

North East Lincolnshire's 2016 Local Plan evidence put terraced homes at 33% of the area's stock, compared with 25% nationally, and described terraces as a particular feature of urban Grimsby and Cleethorpes. That dated comparison is useful context rather than a substitute for current site evidence.

Party walls can reduce exposed area, while solid masonry, rear returns, suspended floors and later insulation work can change the inputs from one street to the next.

Established areas

Older streets sit beside large twentieth-century estates

Central Grimsby, Holme Hill, Old Clee, Wellow, Scartho and Great Coates are all recognised conservation areas. Around and between them are inter-war and post-war semis, bungalows and detached houses where cavity construction may be likely but still needs supporting evidence.

Replacement windows, cavity fill, loft boarding and later ground-floor work can leave neighbouring houses with very different heat-loss inputs.

Growth areas

Western and southern development widens the brief

The Local Plan identifies strategic growth at Scartho Top, Grimsby West around Laceby Acres and Wybers Wood, and the Humberston Road area. These routes add newer detached and semi-detached homes, while Waltham, New Waltham, Humberston and Laceby bring a broader village-edge mix.

Local case study

A detached DN34 home with two additions and mixed heat emitters

This 1983-1990 house had ten surveyed rooms, twelve windows, seven radiators and four floor-plan captures. Wet underfloor heating served the kitchen and dining room, so those spaces could not be treated as if every room followed the same emitter route.

The front porch and rear kitchen addition were recorded separately from the main house. The kitchen's sloping ceiling, pitched roof and solid floor remained distinct, while the seven radiators and two underfloor-heated rooms were assigned to the spaces they actually served.

Main period: 1983-1990
Type: Detached

Survey scope

The original house, two additions and mixed emitters remain distinct

The main house was recorded as 1983-1990 construction. The front porch and rear kitchen addition were assessed separately because their roof, floor and ceiling details differed, while the radiator and underfloor-heating records remained tied to the rooms they served.

Room record

Four plans connect ten rooms across two floors

Ten rooms and twelve windows arranged over two floors
Seven radiators retained against the relevant room data
Wet underfloor heating recorded in the kitchen and dining room
Cavity-fill evidence kept with the main wall assumption

Alterations

The porch and kitchen addition keep their own construction record

The rear kitchen had a sloping ceiling, pitched insulated roof and solid floor. The front porch also had a pitched insulated roof. Recording those elements separately avoids applying the main-house fabric assumptions to later work without evidence.

Loft insulation was measured at 300 mm with around 75% coverage because part of the area was boarded.

Fabric evidence

Cavity and loft evidence stay separate from the additions

Cavity-fill evidence retained with the main wall entry
Loft insulation measured at 300 mm where accessible
Coverage recorded at around 75% because part was boarded
Addition roofs and floors kept outside the main-house assumption

Coverage

Planning survey visits across Grimsby and nearby DN postcodes

The A180, A16 and A1243 carry different parts of the local workload. A central Grimsby appointment, a Cleethorpes visit and work towards Immingham or the southern villages are planned as separate routes rather than interchangeable diary slots.

Main routes

The A180 carries the east-west workload

The A180 connects Grimsby and Cleethorpes with Immingham and the M180. The A16 runs south through the town, while the A1243 and Laceby Road carry western traffic. The council's 2023 business case found several key junctions already over capacity in peak periods.

Outer areas

Coastal, port and village work is grouped from the postcode

Cleethorpes and Humberston form an eastern route. Healing and Immingham sit west along the A180, while Scartho, Waltham and New Waltham draw work south towards the A16. That grouping keeps travel allowances realistic when several appointments share a day.

Installer market

Twenty-three MCS-listed firms sit within the regional radius

When checked on 16 July 2026, a directory using MCS data listed 23 certified air-source heat-pump installers within 30 miles of Grimsby, with 20 shown as Boiler Upgrade Scheme registered. These are radius figures, not 23 firms based inside the town boundary.

Before booking

Questions before booking

Included

What is included in a Grimsby heat loss survey?

The report records each heated room, its dimensions, exposed elements, windows, doors, ventilation, construction assumptions and existing emitters. Later additions and mixed emitter types remain separate where they change the calculation inputs.

Desktop route

Can a Grimsby property be calculated from drawings?

Yes, when the drawings include every heated room and reflect later alterations. A measured visit is more reliable for bay-fronted terraces, extended semis or properties where insulation and floor construction are uncertain.

Area

Which Grimsby areas does Vertex cover?

Coverage includes Grimsby, Cleethorpes, Great Coates, Scartho, Waltham, New Waltham, Humberston, Laceby, Healing, Immingham and surrounding DN postcodes. Vertex also supports installer projects throughout the UK.

Not sure which route the property needs? Read the wider survey questions or send Vertex the postcode with the plans and alteration history available.

Pricing

Confirm the evidence route before reserving a survey date

The quote reflects the heated floor area, the records already available and whether measurements must be collected on site. Travel is confirmed from the full DN postcode before the appointment is accepted.

Room calculation From £150

A standalone room-by-room report using a complete drawing and fabric pack, or a measured visit where those inputs are missing.

Combined ASHP evidence From £350

A single appointment for room data alongside proposed equipment positions, access, electrical details and installer evidence.
