One of the many factors to account when calculating a house renovation cost is if you are doing any structural alterations to your property if so, you will need to add to your budget the structural engineer fees. Perhaps you believe that engineers are only hired for extensions when renovating a house, but the truth is you may have to hire one for other projects, too, such as demolishing a wall, replacing the roof, and other new structural work.
Most engineers charge about £150 per hour on average. The total costs can vary from £400 to £5,000, on average, depending on the project complexity. Engineers are also responsible for carrying out structural surveys this could help to spot any issues with your property and they are also responsible to produce structural drawings, these will be used by the builders when carry out the work. Again, the prices can vary, but a full structural survey can cost about £485-£500.
|Engineer costs||Costs range averages|
|Basic residential project||£350 - £450|
|Complex residential project||£1,500 - £9,000|
|Structural report||£500 - £2,000|
|RSJ calculation||£250 - £950|

If you are not sure if you need planning application for your project visit the planning portal were you can find lots of information regarding building regulations in your area or ask your architect he will be able to advise you if your project is a permitted development or not.

If you live in an older home, an electrical upgrade is one of the first things to include in your house renovation costs. The average cost of replacing an old fashioned fuse box is £1,075, but you might also have to pay for additional work, including:
The figures above, generally include labour costs; however, if you have to carry out other electrical work, you’ll have to calculate labour costs separately. For instance, to replace broken light switches, you can expect to pay around £35-£55 for each broken switch plus the electrician fee of about £45 per hour.
Central heating is one of the most important investments, whether you’re renovating a house for yourself or to sell it. A new heating system for a 3-bed house with nine radiators and a 28 kW boiler, you can expect to pay anything between £2,300–£5,500, depending on fuel source and boiler location. This cost doesn’t include new pipework, which can cost up to £1,000 for an average size home.

A solid roof structure is essential to keep you safe and protected from the elements but also important to maintain you property in good condition. Replacing a roof will cost you about £5,500 on average, but this will depend on the size of the roof and the location of the property, with most homeowners spending between £3,000 and £16,300, depending on the type of roof and project complexity.
Insulating the house’s external walls can help you save on energy and heating bills; however, insulating the walls can cost a small fortune, depending on the type of walls and size of your property.External wall insulation costs around £100 per sq. m., meaning that you can expect to spend about £8,000 for a small flat and over £20,000 for a larger detached house. These figures include scaffolding, but you may have to pay more if more than two storeys a scaffolding are required.
Adding an extra bedroom can raise the value of your property by about 10%, but this is one of the most expensive renovation plans. The size of your extension plans is one of the main factors affecting the cost, but not the only one. You may pay more if you want extra features, such as an en-suite bath. On average, a bedroom extension costs about £16,000 for a small extension, one-storey, ground floor project and can go up to £100,500 for a 6 by 8 two-storey extension. If you wish to add an en-suite, add about £6,500 to the whole room extension costs, on average. If you want to add more than a bedroom, the price will go up depending on how many extra bedrooms you want to add.
Adding more living space to a home is sometimes necessary. For instance, you may want to add new bedrooms for your growing family or incorporate a home office facility. House extension costs can vary widely, based on the location of your home (building an extension in London is much more expensive than building one in Lancashire, for example), extension, size, ease of access, permission, and other additional costs, such as hiring an architect.

Installing a new bathroom can increase the value of older properties. Provided you have already extended the house, the project will cost about £4,500 on average, including materials and labour.
Renovating a main bedroom, including changing the furniture, costs about £3,000 on average for standard quality. Smaller refurbishments of your sleeping space or small improvements – such as painting the walls or the ceiling to enhance the original ceiling value – are more cost effective, though, most homeowners spending £1,000 on average; a great way to save money while still enhancing your home.
The costs go sky-high if you aim for premium finishes and bespoke solutions. A complete revamp of your master bedroom can cost £40,000 on average, including custom-made fittings and finishes and professional interior design.
