Runcorn's commercial property is concentrated in the Astmoor and Manor Park industrial areas, with science and office space at Sci-Tech Daresbury nearby. No two of those buildings are the same, which is why every quote starts with a survey of the roof space.
Older industrial buildings and mill conversions often have roof voids with little or no insulation, or insulation decades old that has slumped. We strip out what is there if it needs to come out, then refit to current standards.
Every job starts with a survey of the roof space, followed by a written quote per square metre that sets out what comes out, what goes in and to what depth. We plan the work around your opening hours and shift patterns, and on bigger buildings we work zone by zone so the business keeps running.
Industrial property around Astmoor, Manor Park and Sci-Tech Daresbury includes everything from older mill and brick buildings to modern units. Older buildings in particular often have roof voids with little insulation, or insulation that is decades old.
Workshops and industrial units are often heated for long hours, sometimes with high ceilings that let warm air gather where it does no good. Where there is a ceiling with a void above it, the insulation in that void decides how much of the heat escapes, and in older buildings it is often thin, slumped or missing altogether.
We plan the work around production, shifts and machinery, agree safe access with your site team, and keep the work areas below protected while we are in the void.
Commercial work is priced per square metre of roof void, typically between £3 and £12 per m². Where a job sits in that range depends on the depth of insulation, how easy the void is to reach and work in, and whether old insulation has to come out first. The examples below are worked out from that range, and the highlighted row is the type of building most typical of Runcorn's commercial areas.
| Building | Example roof void area | Typical price |
|---|---|---|
| Workshop or industrial unit | 600 m² | £1,800 to £7,200 |
| Shop or retail unit | 120 m² | £360 to £1,440 |
| Top floor of an office building | 400 m² | £1,200 to £4,800 |
| Warehouse office and welfare block | 250 m² | £750 to £3,000 |
| Larger office building or mill floor | 1,500 m² | £4,500 to £18,000 |
Examples only. Your written price comes after the survey.
The 0% VAT rate on insulation only covers homes and some charity buildings, so work on commercial premises is charged at the standard rate of 20%. If your business is VAT-registered, you can usually reclaim it in the normal way.
We offer 0% finance for qualifying businesses, so the upgrade can be paid for out of the energy savings rather than up front.
A good insulation job depends on what is already in the roof void and what else is up there. On every survey we check the following.
In England and Wales, landlords cannot continue to let most non-domestic property with an EPC rating of F or G unless a valid exemption is registered. Since 1 April 2023 that has applied to existing lettings as well as new ones, and it is enforced by local trading standards. Roof insulation is one of the measures an EPC assessor takes into account.
A commercial building needs an EPC when it is sold or let, and the certificate lasts 10 years. If yours is coming up for renewal, insulating the roof first can help the new rating.
Laying insulation in a roof void does not usually need approval on its own. If the insulation is part of renovating the roof, Part L of the Building Regulations can require the renovated part to meet a minimum standard, and the work may need signing off. In Runcorn that goes through Halton Borough Council building control or a registered building control approver. Our Part L guide explains more.
Insulating inside a roof void rarely needs planning permission, but listed building consent can apply to works inside a listed building. If yours is listed, speak to the conservation officer at Halton Borough Council before booking.

Common questions about upgrading business premises
Yes. Runcorn is about 21 miles from our base in Cheshire, and we also cover Widnes, Warrington and St Helens and the rest of Cheshire.
Roof spaces and ceiling voids in offices, warehouses, shops and industrial units, including around Astmoor, Manor Park and Sci-Tech Daresbury.
Not usually for straightforward roof-void insulation. If the insulation is part of renovating the roof, the work may need Building Regulations sign-off through Halton Borough Council building control or a registered building control approver, and listed buildings can need consent.
Many commercial buildings have insulation that is old and slumped, damaged, or too thin at 100mm or less. Upgrading to current standards of 270mm or more can save a further 20 to 30% on energy bills and is often needed to improve EPC ratings for leasing.
High-grade mineral wool such as Knauf Earthwool, which performs well thermally and is non-combustible, with a Euroclass A1 fire rating.
We don't lay insulation straight onto suspended ceiling tiles, because it adds weight and gets disturbed every time a tile is lifted. The survey looks at the best place for it instead, and we will tell you whether that is a job we can do.
Insulation makes the void above it colder, so ventilation matters. We keep the eaves and roof vents clear, check for existing damp on the survey and tell you about anything that needs fixing first.
Yes. When the work is finished we provide documentation confirming it meets Part L of the Building Regulations, for your property records, insurance, and any future sale or lease.
Roof insulation is one of the measures an EPC assessor takes into account, though how far it moves the rating depends on the building, its heating and its lighting. Landlords should note that most commercial property cannot be let with an EPC below E unless an exemption applies.
Energy audits are free for commercial properties over 5,000 sq ft. For smaller premises, send photos of the roof void and the rough floor area through the quote form and we will come back with a price.
We specialise in keeping disruption to a minimum. We offer out-of-hours installation in the evenings and at weekends, and can work in phased sections so your business keeps running during the project.
Yes. We offer 0% finance for qualifying businesses, so you can spread the cost and pay for the upgrade from the energy savings.
