How to compare electrician quotes
Before comparing the totals, check that each electrician is pricing the same work. The number and position of fittings, cable routes, access, testing and finishing arrangements can all change what is included.
This guide is for homeowners planning electrical work in Liverpool, Birkenhead and the Wirral. It helps you ask useful questions before booking, whether you need extra sockets, lighting, a consumer unit replacement or a larger project.
Start with the same brief
Give each electrician the same list of work. For a room refurbishment, mark the proposed socket and light positions on a simple plan and say which fittings you already own. Explain whether rooms will be occupied and whether other trades will be working at the same time.
For work beyond a minor job, Electrical Safety First recommends obtaining at least three written quotations. Ask each contractor to identify assumptions and exclusions so you can compare the proposals fairly.
If you are still deciding what the project needs, start with our guide to planning electrical work.
Check the work and equipment included
A description such as “new sockets” leaves important details open. Ask for the quantity, location, finish and any agreed features. For equipment such as an EV charger or consumer unit, ask which product or specification has been allowed for and what installation work is included.
Are the fittings supplied by the electrician or by you?
Are cable routes and any visible surface containment agreed?
Does the price include removing the fittings being replaced and taking away the resulting electrical waste?
Are optional upgrades shown separately from the agreed work?
If you change your preferred fittings or their positions, ask for the price to be updated before ordering or starting. A quotation based on one specification cannot reliably be compared with a proposal for different equipment.
Separate installation from fault investigation
When the cause of a fault is unknown, an electrician may need to investigate before a repair can be priced. Ask what the initial charge covers, how further time is charged and when you will receive an update. An investigation allowance does not necessarily include the eventual repair.
For a known installation job, ask whether the price is a quotation for the stated scope or an estimate that may change. Have any conditions explained in writing. See our electrical fault finding service for help with an unresolved fault.
Agree access and making good
Concealed wiring may require access below floors or openings in walls. Discuss the likely route, furniture that needs moving and who will arrange access. Tell the electrician about tiled floors, fitted furniture, recently decorated rooms or other restrictions before the price is agreed.
Ask what condition the area will be left in and who will handle any repairs to finishes. Lifting a floorboard, cutting a cable chase, filling a wall and decorating it are different tasks. Do not assume a quotation includes all of them.
Dan’s electrical work does not include plastering or decorating. Arrange those trades separately where needed and allow for them in your overall project budget. Agree access and any other finishing responsibilities for your particular job before work starts.
Ask about testing and completion documents
Ask which inspection, testing and completion documents apply to the quoted work. The document depends on the job: an Electrical Installation Certificate or a Minor Electrical Installation Works Certificate may be appropriate. An EICR is a report on the condition of an installation, rather than the completion certificate for new installation work.
For work in England that requires Building Regulations notification, confirm who will handle it and how you will receive the compliance documentation. The electrical certificate and the Building Regulations compliance certificate serve different purposes. Ask the electrician to explain what you should expect and when.
Compare the full price and terms
Read the payment terms alongside the scope. Check whether VAT applies and whether it is included in the total, any deposit requested, when the balance is due and how long the quotation remains valid. Ask about the expected working period and any planned interruptions to the power supply.
Also check how additional work will be agreed. For example, access might reveal a problem that could not be confirmed during the initial visit. Ask for an explanation, the proposed remedy and any price change before authorising additional work. Agree a contact arrangement if you will be away from the property.
An example of two different proposals
Imagine two quotations for four additional sockets. One allows for white fittings and visible surface cable routes, with clear access. The other allows for a different finish and concealed routes that require openings in the walls, with plastering arranged separately. The totals cover different work. Ask both electricians to price the same agreed layout, finish and access arrangements before deciding.
This is an illustrative comparison, not a quotation or a description of a completed customer job. It shows why a lower total alone does not establish which proposal suits your project.
Check the contractor as well as the quotation
Verify registration directly with the relevant scheme, ask about insurance and look for references for similar work. Confirm who will carry out the job and who you should contact with questions. If a builder is arranging the electrician, establish the same details before work begins.
You should have time to understand the proposal. If something is unclear, request a written explanation or a revised quotation before accepting it. Keep the agreed scope, any later changes, the invoice and completion documents together.
Questions before you accept
Does the quotation describe the quantities, positions, products and cable routes we agreed?
Are access, waste removal and finishing responsibilities clear?
Are testing, relevant certificates and any required notification accounted for?
Is the total clear, including VAT where applicable, with payment dates and validity stated?
Do I know how changes will be approved and who will be carrying out the work?
Common questions
Should I always choose the cheapest electrician quote
Compare the scope, equipment, exclusions and contractor details first. A lower price may reflect a simpler installation or fewer tasks. Ask about any unexplained difference rather than assuming what it means.
Can photographs replace a visit
Photographs may help an electrician understand the request, but access or the existing installation may still need checking before a firm price is possible. Only send photographs you can take safely with covers closed. Never remove covers or approach damaged equipment to obtain a picture.
Does electrical work include plastering and decorating
Only if that work is expressly included in the agreed scope. Dan does not include plastering or decorating. Allow for these separately and agree who is responsible for any other making good.
What if I want to change the work after accepting
Tell the electrician before the affected work starts. Ask for the change, any price difference and any effect on timing to be confirmed in writing, then agree the revised scope.
Discuss your electrical project
