Building Construction and Renewable Energy Installers in Dudley

Dudley is twenty minutes from us and we are on sites across the borough most weeks. We do three things here and we do them with our own staff: building construction, solar and heat pumps. Extensions and renovations across DY1 to DY9, MCS certified solar on some of the highest ground in the West Midlands, and air source heat pumps sized from a heat loss calculation. Insulation sits alongside all three. One project manager, from the first survey to the final certificate.

Building, Solar, Heat Pumps and Insulation in Dudley

Every service below is delivered by our own in-house team rather than subcontracted out. Building work runs through one project manager with planning and Building Control handled by us, solar and heat pump installations are MCS certified, and insulation is specified after a survey rather than off a price list.

Areas We Cover Across Dudley Borough

The same in-house team works across the whole borough, from Dudley town and Netherton up to Sedgley and Gornal, out through Brierley Hill, Kingswinford and Wordsley, and down into Stourbridge, Lye and Halesowen. Nearly all of it is inside half an hour of us, which is why a mid-project site visit here is never a problem.

A Borough Built on Coal, and What That Means for Your House

Most of the country does not have to think about what is underneath a house before building on it. Dudley does. The borough sits on the South Staffordshire coalfield, the seam was shallow and it was worked for centuries, and the limestone under Wren's Nest and Castle Hill was mined out until the hillsides were honeycombed. None of that is history for a builder. It is the first thing that decides what the foundations have to do.

In practice it means a Coal Authority mining report before the drawings are finalised, and on some plots a ground investigation after it. That applies to anything touching the ground, so single storey extensions, loft conversions with new structural support, and full home renovations all start there rather than at the design stage. A report costs a few hundred pounds and a week. Redesigning foundations after the digger has turned up costs considerably more than that.

Dudley Housing, Street by Street

The borough is not one kind of house and it cannot be quoted as though it were. Netherton, Lye, Quarry Bank and the older parts of Brierley Hill are mostly pre-1920 terraces with solid nine-inch brick walls and no cavity at all. Gornal, Coseley, Kingswinford, Wall Heath and Wordsley are largely interwar and post-war semis, usually with a narrow cavity that was never filled. Pedmore, Oldswinford, Wollaston and Norton run to bigger Edwardian and interwar detached houses, with suspended timber floors, bay windows and large cold roof voids.

Those three groups need three different answers. The semis take cavity fill and a proper loft insulation job. The solid wall terraces cannot be injected at all and need external wall insulation instead, finished in render. The larger older houses usually lose most of their heat through the roof and the floor before the walls are even worth discussing, and often need a heating system upgrade sized for the house rather than inherited from whatever was there before. Which group yours falls into is decided at survey, not on a price list.

What to Do First, and in What Order

The most expensive mistake we see in this borough is putting generation and heating onto a cold house. A heat pump on an uninsulated solid wall terrace has to be bigger, costs more to buy, costs more to run and still struggles in February. The order that works is fabric first: loft, then walls, then the generation, then the heating sized for the warmer house you now have rather than the colder one you started with.

That is why our survey covers the whole property even when you only asked about one thing. If the house is already in good order, solar PV with battery storage or an air source heat pump can go straight in and we will say so. If it is not, we will tell you that too, and tell you what to do first. Nobody has ever thanked us for selling them a system their house was not ready for.

Working on Dudley Sites

The ridge through Sedgley, Gornal and Turner's Hill is some of the highest ground in the West Midlands, which means scaffold has to be tied and braced for real wind loading up there rather than signed off out of habit. Down in the older terraced streets the problem is the opposite: rear entries, shared drives and no off-street parking, so skips, scaffold and deliveries have to be planned before week one, not discovered during it. Planning and Building Control go through Dudley Metropolitan Borough Council, and the conservation areas at Stourbridge, Oldswinford, Wollaston, Amblecote, Wordsley and Sedgley change what is permitted on a frontage.

We work for homeowners, for landlords with single properties and portfolios, and for commercial sites on planned maintenance contracts. The same team that fits a kitchen renovation or reworks a living room also carries out the energy work, which is the whole reason it can be sequenced properly. One project manager stays on the job from the first survey to handover.

  • Builders, electricians, heating engineers and insulation fitters all in-house
  • Mining report and ground conditions checked before design, not after
  • Planning, Building Control and party wall notices handled by us
  • MCS certified for solar PV and air source heat pumps
  • Free survey at the property, never a price quoted down the phone
  • Written workmanship warranty on every completed job

Dudley is one of six areas we work in, and the same team, the same certification and the same warranty apply wherever the job is.

If you would rather spread the cost of a larger job, the terms are set out on our finance page.

We required an urgent new boiler installation due to the old one breaking down and being unrepairable. Greentek Energy supplied and fitted a new one at very short notice so our tenants could have heating and hot water again. We are very grateful to Greentek Energy and would recommend them highly.

Frequently asked questions

Which parts of Dudley do you cover?+
We cover the whole borough: DY1 to DY9 and the Halesowen B62 and B63 postcodes. That takes in Dudley town, Netherton, Sedgley, Gornal, Coseley, Brierley Hill, Quarry Bank, Pensnett, Kingswinford, Wordsley, Stourbridge, Lye, Amblecote and Wall Heath. Tipton and Bilston are covered too.
Do you take on extensions and structural work, or only energy jobs?+
Both. Building work is what the company does most of. Single storey extensions, loft conversions, knock-throughs, kitchens and full renovations all run through our own team, with planning, Building Control, party wall notices and structural calculations handled by us rather than left to you.
Do I need a mining report before building in Dudley?+
Often, yes. The borough sits on the South Staffordshire coalfield with historic shallow coal and limestone workings beneath parts of it. A Coal Authority mining report, and sometimes a ground investigation after it, tells us what the foundations have to do. We check this before design, not after.
Which should I do first, insulation or a heat pump?+
Insulation, almost always. A heat pump on a cold house has to be bigger, costs more to buy and more to run, and still struggles in February. Loft first, then walls, then generation, then the heating sized for the warmer house. We survey the whole property before advising.
Do I need planning permission for work in Dudley?+
It depends on the job. Most roof solar and many rear extensions fall under permitted development. Conservation areas change that, and Dudley borough has several, including Stourbridge, Oldswinford, Wollaston, Amblecote, Wordsley and Sedgley. Listed buildings always need consent. We check with Dudley Council before quoting.
Do you work for landlords and commercial sites in Dudley?+
Yes, both. For landlords, lifting an EPC rating before a letting is the most common job, and we phase work around tenancy changes so voids stay short. For commercial sites we run planned preventative maintenance contracts, with scheduled visits and a written record after every call.
Can I spread the cost of work in Dudley?+
Yes. Finance is available on most of our installation and building work in Dudley, so a larger job can be spread over a term rather than paid in one go. The options, the terms and how to apply are all set out on our finance page.
